Whitepaper

Management Summary — the ten most important statements
  1. According to the prevailing view, transferable and independently assessable crypto assets are generally eligible for contribution in kind; the property classification as defined in Section 90 of the German Civil Code (BGB) is not required. The Federal Fiscal Court (BFH) classified them as assets with measurable value and marketability (February 14, 2023, IX R 3/22) – however, this ruling pertains to tax law; a supreme court decision regarding contributions in kind to limited liability companies (GmbHs) is lacking.
  2. There isn't one, but six ways Incorporating capital into a GmbH (limited liability company) involves significant differences in effort, tax consequences, and liability. Capital increases in kind are the most well-known, but rarely the most cost-effective.
  3. The critical point is not the admissibility, but the Value retention. The registry court will reject the application if the contribution in kind is not insignificantly overvalued (§ 9c para. 1 sentence 2 GmbHG) — a real risk given that the value fluctuates by double digits within 48 hours.
  4. The decisive factor is the value in Time of registration in the commercial register; The expert opinion deadline may differ and must be updated by the registration date. There are often weeks between the decision and registration.
  5. A conscious Safety margin Under company law, this is permissible and even required—the prohibition is directed against overvaluation, not undervaluation. However, undervaluation is not without tax consequences (Chapter 7).
  6. The open contribution in kind against shares is tax-deductible. exchange-like process = Sale. If acquired within one year, a taxable profit arises in private assets according to § 23 EStG — without any inflow of liquidity.
  7. OPEN LEGAL QUESTION: According to Section 23 Paragraph 1 Sentence 5 of the German Income Tax Act (EStG), there is much to suggest that the hidden contribution to the capital reserve This does not trigger any legal transaction (the legal fiction only applies to real estate). There is no definitive ruling from the highest court regarding crypto assets.
  8. The Proof of ownership This is the most frequently underestimated point. A screenshot is not proof — reliable evidence consists of cryptographic signatures, test transactions, and complete documentation of origin.
  9. The mere management of one's own assets does not require a license. However, repeated OTC transactions, prior agreements, or procurement for third parties may constitute crypto asset services; Section 46 of the German Crypto Asset Management Act (KMAG) criminalizes violations.
  10. The Time required This is underestimated: realistically, from decision to registration takes eight to fourteen weeks, and even longer if the registry court is inexperienced with crypto.

From the private key to the balance sheet. Volatility, proof of control, and choosing the right path are challenging.

1 Introduction: Why invest crypto assets in a corporation

For real estate, machinery, and company shares, well-established procedures have existed for decades: the value can be verified by expert appraisals, the transfer of ownership can be documented, and registry courts routinely review such transactions. With crypto assets, however, entrepreneurs, notaries, and registry courts are largely entering uncharted territory—with an asset whose value can change by double digits within 48 hours and whose ownership depends not on a document but on a private key.

This leads to the fundamental problem: Corporate law rules regarding contributions in kind are designed for stable, appraised assets. They also apply to crypto assets—they just don't fit directly. Anyone who overlooks this risks liability for the difference in cash, a tax burden without any inflow of liquidity, or a registration process lasting months.

The question of whether crypto assets should be held as personal wealth or in a corporation is being raised by a growing number of entrepreneurs, family offices, and high-net-worth individuals. The trigger is rarely a single motive, but rather a combination of five key reasons.

1.1 Asset protection and separation of liability

Cryptocurrency assets held as private property are directly subject to the claims of private creditors. A limited liability company (GmbH) creates a separation of liability: the company's assets are liable for the company's debts, not those of the shareholders. While the shareholding is subject to seizure, the underlying cryptocurrencies are not directly subject to seizure—provided the contribution is not made during a crisis or with the intent to defraud creditors. Sections 129 et seq. of the German Insolvency Code (InsO) and the German Act on Contestation of Legal Transactions (Anfechtungsgesetz) set clear limits; a contribution made at the last minute is contestable and may have criminal implications.

1.2 Professional Trading and Retained Earnings

Those who actively trade their assets lose the tax exemption after one year and risk being classified as commercial traders. In a limited liability company (GmbH), trading activities are systematically considered business assets. The tax rate on retained earnings, including corporate income tax, solidarity surcharge, and trade tax, is around 30 percent, depending on the local tax multiplier—significantly below the top income tax rate. The price: The tax exemption after a one-year holding period is completely lost, and a second level of taxation is added upon distribution.

1.3 Succession planning

Shares in a company can be linked to voting rights, usufruct, restrictions on disposal, pre-emption rights, and succession provisions in the articles of association. Crypto assets are technically almost infinitely divisible, but on their own do not offer comparable control and binding options. Furthermore, access to private keys poses the greatest operational risk in the event of inheritance. A company with documented key management, a four-eyes principle, and regulated representation solves a problem that regularly causes private estates to fail.

1.4 Financing and creditworthiness

Cryptocurrency assets held privately do not appear on any company balance sheet. Contributed as share capital or capital reserves, they increase the equity ratio and can improve creditworthiness. However, practice is more sobering than theory: many credit institutions assess crypto holdings conservatively or not at all in their ratings. The effect does occur, but should not be overestimated.

1.5 Professionalization and Documentation

The most practically significant reason: The legal form of the company enforces order. The obligation to keep accounts, prepare annual financial statements, and comply with the record-keeping requirements of the German Federal Ministry of Finance's letter of March 6, 2025, ensures that transaction history, proof of origin, and valuations are systematically maintained. Once this structure is established, companies are significantly better positioned for tax audits, bank inquiries, and inheritance matters.

When investing is not worthwhile

Typical arguments against contributing assets include: a pure buy-and-hold portfolio that could be sold tax-free after the one-year holding period anyway; holdings below a size that doesn't cover the company's ongoing costs; and the intention to access the assets privately in the short term—every distribution triggers a second level of taxation. As a rough guideline: below a mid-six-figure sum, the structure is often not viable. This isn't a hard and fast rule, but rather a reason to recalculate.

Key messages
  • Holding crypto assets in a GmbH (limited liability company) is legally permissible; the question is not whether, but how and at what price.
  • The five typical motives are asset protection, professional trading, succession planning, financing, and documentation quality.
  • The advantage of retained earnings is offset by the loss of the one-year holding period exemption and the second level of taxation upon distribution.
  • The contribution must not serve to disadvantage creditors; Sections 129 et seq. of the Insolvency Code and the Avoidance Act set clear limits.
  • In pure buy-and-hold strategies and with smaller portfolios, the company structure is often not economically viable.

2. An overview of the six contribution methods

In consulting practice, the question is usually narrowed down to capital increases in kind. In reality, six options are available, which differ significantly in terms of effort, tax consequences, and liability risk.

1. Sale to the GmbH. The shareholder sells coins at market price; the purchase price is either paid in full or left as a loan. The simplest way: no notary, no commercial register, no formal incorporation report. The price must be at arm's length. For the shareholder, this constitutes a sale; after a one-year holding period, it is tax-free as private assets.

2. Contribution in kind upon incorporation. Coins are contributed to the share capital upon incorporation. This requires: a stipulation in the articles of association, a report on in-kind contributions (§ 5 para. 4 GmbHG), and full payment before registration. They are considered business assets from the outset; however, the report is complex due to volatile values, and the standard articles of association are not permitted.

3. Contribution in kind during a capital increase. In the case of an existing company, the share capital is increased. The object of the company and the nominal amount must be clearly defined in the resolution to increase the share capital (Section 56 Paragraph 1 of the German Limited Liability Companies Act (GmbHG)). A report on contributions in kind is not required; the commercial register court examines the value of the contributions pursuant to Section 57a in conjunction with Section 9c Paragraph 1 of the GmbHG — inquiries are to be expected in the case of crypto assets.

4. Shareholder loans. Coins are provided as a loan (loan in kind, repayment in the same type and quantity). Flexible and informal, but it does not create equity capital, is subordinated in insolvency proceedings (§ 39 para. 1 no. 5 InsO), and raises the question of appropriate interest rates. More of an interim solution.

5. Contribution to the capital reserve. Transfer without consideration; booking to the capital reserve (Section 272 Paragraph 2 No. 4 of the German Commercial Code). From a company law perspective, this is the simplest way: no capital measure, no notary, no registration, no valuation test. For tax purposes, it is a hidden contribution—with significant consequences (Chapter 6). Prerequisite: sole shareholder or unanimity.

6 · Trust models. A trustee holds the coins on behalf of the company. From a regulatory and tax perspective, this is the most complex structure: the economic attribution (§ 39 para. 2 no. 1 AO) must be verifiable, and depending on the specific arrangement, the trustee provides a custody service requiring a license. It is strongly discouraged without specialized advice.

Practical opinion of Finanz Forensik GmbH — The most common misconception in consulting practice

Many clients come to us with the firm belief that a capital increase in kind is essential—because it appears "official" and "clean." In the vast majority of cases, this is the most complex and expensive way to achieve a result that could have been reached just as easily through capital reserves or a simple sale. A capital increase in kind only makes sense if the increased share capital itself is desired: as a signal to banks, to adjust shareholding ratios, or because a specific share capital figure is contractually required.

Key messages
  • Six options are available; the increase in equity capital is the best known, but rarely the most economical.
  • The sale and contribution to the capital reserve do not require a notary, registry court, or valuation check.
  • The choice of method determines the tax consequences for the shareholder — not the amount contributed.
  • Shareholder loans do not create equity capital and are subordinated in the event of insolvency.
  • Trust models are risky from a regulatory perspective and are not recommended without specialized advice.

3 Company Law: Requirements for contributions in kind

3.1 Eligibility for contribution in kind

Prevailing opinion no supreme court ruling specifically on the contribution of crypto assets in kind

Any asset whose economic value can be determined and which can be transferred to the company is eligible for contribution. A tangible asset as defined in Section 90 of the German Civil Code (BGB) is not required—otherwise, receivables, licenses, and software would not be eligible for contribution. What is required is marketability, independent valuation, and the ability to grant the management unrestricted control over the asset.

These requirements are met for crypto assets. In its ruling of February 14, 2023 (IX R 3/22), the Federal Fiscal Court (BFH) decided that currency tokens are digital assets with measurable value and marketability (confirmed in paragraph 31 of the Federal Ministry of Finance's letter of March 6, 2025). This decision pertains to tax law and does not directly address the corporate law question, but it does provide the crucial building blocks: independent valuation and marketability. There is currently no explicit ruling from the highest court regarding contributions in kind to a limited liability company (GmbH).

3.2 Report on the contribution in kind and registration review

1ApplicationNotarial certification andRegistration forCommercial Register2TestThe registry court is reviewing this.Value (§ 9c GmbHG)3InquiryIf applicable, evidence orCertificate of Value4registrationEntry — or rejectionovervaluation

In the case of contributions in kind, Section 5 Paragraph 4 of the German Limited Liability Companies Act (GmbHG) requires a contribution in kind report in which all shareholders explain the circumstances relevant to the appropriateness of the valuation. Such a report is not required for capital increases—the valuation assessment then rests solely with the registrar. Pursuant to Section 57a in conjunction with Section 9c Paragraph 1 Sentence 2 of the GmbHG, registration must be rejected if contributions in kind have been significantly overvalued. Submitting a well-prepared application significantly shortens the process.

3.3 What belongs in the report on in-kind contributions

  • Exact description of the deposited item by type and quantity — not „Bitcoin worth X“, but „n,nnnnnnnn BTC“ along with the company's receiving address;
  • Origin of the crypto assets: time of acquisition, type of acquisition, purchase price, trading venue;
  • Evaluation method including trading venues, time period and weighting;
  • Valuation date and justification for the choice of valuation date;
  • Volatility during the observation period and justification for the safety margin;
  • Proof of the depositor's power of disposal prior to transfer;
  • Proof of transfer to an address controlled by management (transaction hash);
  • Description of the custody structure (cold storage, multi-signature, access control).

3.4 Liability for differences and hidden contributions in kind

If the value of the contribution in kind does not reach the nominal amount assumed at the time of registration, the shareholder is liable in cash for the shortfall pursuant to Section 9 Paragraph 1 of the German Limited Liability Companies Act (GmbHG). Liability for differences The central economic risk with volatile stocks is this: if the price falls between the decision and registration, a margin call in cash is required.

A second risk lies in the hidden contribution in kind According to Section 19 Paragraph 4 of the German Limited Liability Companies Act (GmbHG), this applies when a cash contribution is formally agreed upon, but an in-kind contribution is economically intended—for example, when a shareholder pays in money and the company directly acquires their coins with it. The contribution obligation is then not fulfilled; the value is merely credited, and the burden of proof lies with the shareholder.

Practical tip — tight scheduling

Notarization, transfer of the coins, precise valuation, and registration should all take place within one week. Only schedule the notary appointment once the custody structure, valuation documents, and proof of ownership are complete—not the other way around. The notary can usually register the transaction the day after notarization, provided all documents are complete. This is precisely where most problems arise.

Time trap. The decisive factor for the asset's value is its registration in the commercial register. Days to weeks pass between the resolution and registration, and further weeks between registration and entry. With a value that can fall by 20 to 30 percent, the safety margin is not a precautionary measure, but a necessity—the alternative is liability for the difference in cash.

3.5 What does each document do — and who signs it?

documentContent and functionWho signs — with what responsibility?
Report on in-kind contributionsExplanation of the circumstances relevant for the valuation (§ 5 para. 4 GmbHG)All shareholders; liability for the accuracy of the information
Insurance § 8 para. 2 GmbHGConfirmation that the deposit has been made and is available for useManagement; criminally liable under Section 82 of the German Limited Liability Companies Act (GmbHG).
Technical Assessment FacilityPrice sources, methodology, volatility, derivation of the discountTechnical service provider; data basis, no expert responsibility.
Certificate of ValueConfirmation that the value has reached its nominal valueAuditor / Expert; professional liability
Expert opinionIndependent valuation with justification of methodologyExpert; liability for the expert opinion result
Blockchain proofSignature protocol, test transaction, transaction hashes, custody confirmationtechnical service provider; factual report, independently verifiable

For a limited liability company (GmbH), only the contribution in kind report (at the time of incorporation) and the managing director's declaration are legally required. All other documents are voluntary—however, their submission determines whether the commercial register will have any further inquiries. A technical valuation system does not replace a valuation certificate: it provides the data, not the professionally responsible statement regarding the value.

Key messages
  • According to the prevailing opinion, crypto assets can be contributed as assets in kind; the property-like quality required under Section 90 of the German Civil Code (BGB) is not necessary. A ruling from the highest court is lacking.
  • A report on contributions in kind is mandatory when a company is founded; in the case of a capital increase, the registry court reviews the case independently.
  • The relevant valuation date is the registration in the commercial register, not the resolution.
  • If the value does not reach the nominal amount, the liability for the difference applies in cash according to § 9 GmbHG.
  • The detour via cash capital increase and purchase can constitute a hidden contribution in kind (§ 19 para. 4 GmbHG).

4. Valuation of Crypto Assets

4.1 The principle: fair market value

The benchmark is the value that could be obtained in ordinary business transactions upon sale. For established cryptocurrencies with deep, liquid markets, this is the market price. The difficulty lies not in the benchmark itself, but in defining it: there is no officially fixed price, quotes differ between trading platforms, and the price changes every second.

4.2 Four evaluation methods

Prevailing opinion There is no explicit regulation for the valuation of volatile contributions in kind.
methodProceedfitness
Key date pricePrice of a defined trading venue at a defined timeOnly for very short periods of time; susceptible to criticism
Daily averageVolume-weighted average of a trading day across multiple exchangesA practical standard for smaller contributions
Weighted average (period)Volume-weighted over 3–6 months, analogous to Section 33a Paragraph 1 No. 1 of the German Stock Corporation Act (AktG).Justifiable for volatile values, based on a familiar regulation.
Expert opinionValuation by auditors or expertsFor larger volumes, illiquid tokens, and foreseeable queries

The reliance on Section 33a Paragraph 1 No. 1 of the German Stock Corporation Act (AktG) is methodologically sound: This provision permits the valuation of securities using the weighted average price of the last three months, thus addressing precisely the problem – short-term fluctuations should not distort the valuation. Anyone who discloses and justifies this analogy in the report on incorporation in kind is arguing on familiar ground, even for a registry court without experience with cryptocurrencies. However, a historical average does not replace the examination of the current market value on the registration date.

4.3 Dealing with volatility

  • Temporal smoothing: Averaging over a longer period instead of a fixed-date price.
  • Safety margin: deliberate approach below the determined value — the required buffer (Chapter 7).
  • Time-saving measures: Reducing the time between valuation, notarization, transfer, and registration. The most effective and most frequently neglected measure.

4.4 The valuation date

1Valuation dateday which thedetailed reviewturns off2Deposit amountTransfer of coins tothe company's address3RegistrationValuable and freeDisposition — relevanttime4Register checkmay several weeks laterlay

This sequence does not imply that the valuation report must be dated to the filing date. A two-stage documentation approach is appropriate: a detailed valuation as of a defined date, supplemented by a brief confirmation of its relevance and value as of the filing date. A valuation based solely on a distant date without any updates is open to challenge.

Typical mistake

An appraisal is prepared four weeks before notarization and submitted unchanged. However, the registry court assesses the value as of the filing date—thus, the appraisal answers the wrong question. Remedy: a detailed appraisal as of the relevant date plus a unilateral, date-specific confirmation of the continued value as of the filing date.

Key messages
  • The benchmark is the fair market value; for liquid crypto assets, the market price.
  • The recommended standard is the volume-weighted average price over 3–6 months (analogous to Section 33a Paragraph 1 No. 1 of the German Stock Corporation Act).
  • Use multiple trading venues and justify your selection — single price sources are vulnerable to challenge.
  • An expert opinion is considered for larger volumes and illiquid tokens.
  • The value must be valid on the filing date; a date-specific confirmation must be part of the documentation.

5. Proof of ownership and disposal

This chapter addresses the most frequently underestimated point. Notaries, registry courts, auditors, and banks are increasingly asking how it can be proven that the contributor had the right to dispose of the assets before the transfer and that the company subsequently gained unrestricted access. A screenshot of the wallet balance does not answer this question.

5.1 What proof must provide

1Power of disposalof the person who is putting the pickle before thetransmission2transmissionEnforcement on theCompany address3Free disposalthe management afterwards4Middle OriginSource of Funds —Money laundering prevention

5.2 Cryptographic signature (Proof of Ownership)

The most reliable instrument. The owner signs a message with pre-defined, individual text—such as company name, date, and deed register—using the private key of the originating address. Whoever can generate the valid signature controls the key. The signature can be independently verified by any third party and requires no physical movement of the coins. The individual text links the proof to this specific deposit transaction.

5.3 Test transaction

Additionally or alternatively, a small amount is sent from the originating address to the destination address. This is publicly traceable and practically proves the transferor's control. The disadvantage is network fees, and the attribution is only possible based on the proximity in time. In UTXO chains, the amount can end up in a change output, complicating the attribution process.

5.4 Blockchain proof of transfer

The transfer is documented via the transaction hash. The documentation includes the complete hash, sender and recipient addresses, amount, block timestamp (UTC), block height, and number of confirmations. This information can be independently verified using any block explorer—an advantage over any other deposit method that participants rarely utilize.

5.5 Custody by the company

form of safekeepingDescriptionAssessment for the contribution
Hardware wallet (cold storage)Offline storage of the keys, company safeSuitable; put access and representation rules in writing.
Multisignature walletMultiple keys required, e.g., 2 of 3Recommended for transactions of six figures or more; reflects the four-eyes principle.
Approved Provider (CASP)Custody by a CASP with MiCAR approvalSuitable; check the registration status in the ESMA register
Shareholder's walletCoins remain at the previous addressUnsuitable; free disposal by management not verifiable.
Account on trading platformThe holdings remain in a stock exchange account.Only to a limited extent; the account must be in the company's name.
Practical tip — Signature at the notary's office

Draft the signature text together with the notary and include the deed entry, e.g.: "Contribution to the 'Company', Notary File No. '...', 'Date'". Sign in the presence of the notary or have the process recorded – this ensures that the signature is not only technically verifiable but also linked to a specific time and person.

5.6 Proof of Source of Funds

Regardless of corporate law, notaries, credit institutions, and auditors are increasingly demanding proof of the origin of funds. A forensic analysis of the origin of funds—tracing inflows, checking for connections to sanctioned entities, mixing services, or reported entities—provides clarity before third parties raise the question. If assets become suspicious after being contributed, the consequences affect the company: frozen stock market accounts, terminated bank accounts, and, in extreme cases, an investigation against the management.

Practical opinion of Finanz Forensik GmbH — Our approach to the evidence package

A proven method is to submit a complete package of documents jointly to the notary and the registry court: a signed certificate of ownership referencing the deed register; a record of the test transaction; valuation documentation with price sources; proof of transaction with a complete hash; confirmation of the custody structure; and an analysis of the origin of the contributed assets. Submitting this complete package significantly reduces processing time and avoids the ensuing rounds of queries that disrupt the schedule and create additional valuation risk in a volatile market.

Key messages
  • A screenshot of the wallet balance is not proof of ownership.
  • Cryptographic signatures relating to the specific transaction, supplemented by a test transaction, are considered reliable.
  • The target address must be controlled by the company; otherwise, the management lacks the necessary freedom to dispose of it.
  • Multisignature technically replicates the four-eyes principle and is recommended for transactions of six figures or more.
  • A forensic analysis of origins before submission prevents irregularities from affecting society in the first place.

6. Tax treatment

The most expensive cognitive error

The notion that contributing assets to one's own GmbH (limited liability company) is tax-neutral because no money changes hands is incorrect. An open contribution in kind in exchange for shares is a transaction similar to an exchange – a sale. If the acquisition takes place within one year, a taxable gain arises according to Section 23 of the German Income Tax Act (EStG) – taxed at the individual's personal income tax rate, without any cash flow.

6.1 Crypto assets as economic goods

In its ruling of February 14, 2023 (IX R 3/22), the Federal Fiscal Court (BFH) confirmed that currency tokens are "other assets" within the meaning of Section 23 of the German Income Tax Act (EStG). The Federal Ministry of Finance (BMF) letter of March 6, 2025, which replaces the version of May 10, 2022, follows this line of reasoning, consistently uses the umbrella term "crypto asset," and contains, for the first time, detailed regulations regarding recording and cooperation obligations.

6.2 Open contribution in kind against shares

When crypto assets are contributed in exchange for company shares, this constitutes an exchange: coins for shares. At the shareholder level, this is a sale at fair market value. The consequences depend solely on the holding period.

  • Purchase within one year: Taxable private sale transaction (§ 22 No. 2 in conjunction with § 23 para. 1 sentence 1 No. 2 EStG). Profit = fair market value minus acquisition costs, personal tax rate.
  • Purchase over one year: For currency/payment tokens held as private assets, the profit falls outside the scope of Section 23 of the German Income Tax Act (EStG), provided no other income tax provision applies. The company receives acquisition costs equal to the fair market value (Section 6, Paragraph 6 EStG).
  • No extension to ten years For currency/payment tokens (para. 63 of the German Federal Ministry of Finance letter): Lending or passive staking does not trigger a ten-year holding period for Bitcoin/Ether. For utility/security tokens, a case-by-case assessment is required.
  • New deadline after exchange (Paragraph 55): The holding period begins anew after each exchange — recalculate for each tranche.

The second scenario is the most attractive starting point: The shareholder transfers the assets tax-free, and the company begins with a depreciation and disposal base raised to the current value. A subsequent sale by the company only triggers tax on the increase in value that has occurred since the contribution.

6.3 Hidden contribution to the capital reserve

Open legal question Working hypothesis derived from the wording of the law; to be secured before implementation.

If a shareholder transfers the coins without consideration, this constitutes a hidden contribution. A crucial point is a frequently misinterpreted provision: Section 23 Paragraph 1 Sentence 5 of the German Income Tax Act (EStG) treats the hidden contribution as a sale—but explicitly only "within the meaning of Sentence 1 Number 1." Sentence 1 Number 1 covers real estate. Crypto assets fall under Number 2 ("other assets") and are not, according to the wording, covered by this legal fiction.

According to the wording of the law, there is strong support for the view that the hidden contribution of crypto assets by the shareholder does not trigger a taxable event – even within the one-year holding period. A supreme court ruling specifically on crypto assets is lacking; this arrangement should not be implemented without tax review and, in case of doubt, without obtaining a binding ruling. At the company level, the contribution is valued according to Section 6 Paragraph 1 No. 5 of the German Income Tax Act (EStG): generally at its partial value, but at most at its acquisition cost if the asset was acquired within the three years preceding the contribution.

Practical opinion of Finanz Forensik GmbH — The three-year limit — the most important design parameter

The interplay between Section 23 of the German Income Tax Act (EStG) and Section 6 Paragraph 1 No. 5 of the German Income Tax Act (EStG) results in a little-known system: Deposit within three years of purchase → The valuation is limited to acquisition costs; the hidden reserves are transferred to the company and are fully taxed there upon sale. Deposit more than three years after purchase → A valuation based on partial value may be possible (potential step-up). Whether and to what extent this is possible remains unclear due to a lack of case law. This scenario can be significantly more advantageous than an open contribution in kind for longer-term holdings—however, it is not a proven strategy, but rather a hypothesis. Tax implications should be reviewed before implementation and secured in accordance with Section 89 Paragraph 2 of the German Fiscal Code (AO).

Five sizes that need to be distinguished: (1) the value of the contributed crypto assets (fair market value or partial value); (2) the tax treatment for the GmbH (Section 6 Paragraph 6 or Section 6 Paragraph 1 No. 5 of the German Income Tax Act); (3) the acquisition costs of the investment; (4) the addition to the tax equity account (Section 27 of the German Corporation Tax Act); (5) the commercial law acquisition value. The deemed disposal applies only to (1) and (3) — the remaining consequences must be assessed separately, particularly in the case of multiple shareholders.

6.4 Sale to the company

A sale at market price constitutes a disposal; the tax consequences are the same as for a capital contribution and depend on the one-year holding period. The arm's length principle must be observed: an excessive purchase price leads to a hidden profit distribution, an excessively low one to a hidden capital contribution. The valuation must be documented just as carefully as for a capital contribution.

6.5 Ongoing taxation in society

In a limited liability company (GmbH), crypto assets are considered business assets; the one-year holding period does not apply, and any capital gain is taxable. The tax burden from corporate income tax (15% %), solidarity surcharge, and trade tax amounts to approximately 30% %, depending on the local tax rate. The exemption under Section 8b of the German Corporate Income Tax Act (KStG) does not apply—crypto assets are not considered shares in corporations. Upon distribution, a second tax bracket is added (capital gains tax 25% % plus solidarity surcharge; in cases of substantial shareholding, the partial income inclusion method is optional). The advantage of this structure lies in the reinvestment of profits, not in their distribution.

6.6 Value Added Tax

The exchange of conventional currencies for cryptocurrencies and vice versa is exempt from VAT according to the ECJ ruling Hedqvist (C-264/14). No VAT is levied on contributions in kind, provided the contributor is not acting as a business. Contributions from business assets require separate assessment.

6.7 Documentation obligations

The German Federal Ministry of Finance (BMF) letter of March 6, 2025, significantly tightened the documentation and record-keeping requirements and largely assigns the burden of processing to the taxpayer. It is binding for tax years from 2025 onwards. If software is used, process documentation must be created (GoBD). This includes, among other things:

  • Complete transaction history of all addresses and accounts;
  • Acquisition dates, costs and sequence of use; maintain the same method for each wallet (paras. 61 et seq.);
  • Price sources including trading venue and time; uniform valuation (para. 91);
  • Wallet and address directory with assignment to company;
  • Procedural documentation of the software (para. 98 in conjunction with GoBD);
  • Valuation and contribution documents including transaction hashes.

Paragraph 104: The tax authorities may request information on the source of funds, wallet balances on key dates, addresses used, and transaction hash values. Section 147a AO: If the total positive surplus income exceeds €500,000 (from January 1, 2027: €750,000), the documents must be retained for six years (paragraph 105).

Key messages
  • The open contribution in kind is a transaction similar to an exchange = sale — taxable within the one-year period without any inflow of liquidity.
  • After the one-year period has expired, the contribution is tax-free; the company receives acquisition costs equal to the fair market value.
  • According to the wording of Section 23 Paragraph 1 Sentence 5 of the German Income Tax Act (EStG), a hidden contribution does not trigger a taxable event in the case of crypto assets (fiction only applies to real estate).
  • The three-year limit of Section 6 Paragraph 1 No. 5 of the German Income Tax Act (EStG) determines whether the contribution is to be valued at its partial value or at most at acquisition costs.
  • The holding period exemption does not apply to the company; the advantage lies in the retention of profits, not in the distribution.

7 Special Chapters: Undervaluation as a Risk Buffer

This chapter lies at the intersection where corporate law and tax law diverge. With real estate and machinery, the conflict of objectives is manageable because their values hardly change. With crypto assets, it is structural.

7.1 The conflict of objectives

From a corporate law perspective, the direction is clear: The law protects creditors from overvaluation (§ 9c para. 1 sentence 2 GmbHG). The law does not specify a lower limit. Someone who contributes 10 Bitcoins and acquires shares with a nominal value of €100,000, even though the market value is €900,000, does not violate any provision of GmbH law—the excess amount flows into the capital reserve. For tax purposes, the perspective is reversed: Tax law is concerned with the fair market value, not the nominal value. A deliberately low valuation can be considered a partially disguised capital contribution.

7.2 How much of a discount is acceptable?

Open legal question Neither a standard of evaluation nor case law; the following values are a calculation example.

There is no legal limit. A reasonable approach is to derive a value based on four factors: the historical volatility of the specific cryptocurrency, its liquidity, the expected time until registration, and the desired level of security—for example, using a Value-at-Risk approach. The following table is solely a model calculation example, not an industry standard or recommendation:

Period until registrationBitcoin / EtherEstablished altcoinsremark
up to 1 week10 – 15 %20 – 25 %Tight schedule, lowest risk
2-4 weeks20 – 25 %30 – 40 %Typical practice case
over 4 weeks30 – 40 %higher in individual casesShortening the processing time usually has a stronger effect.

A model-based approach without empirical or legal foundation—the values must be derived on a case-by-case basis. The key factor is generally not the size of the discount, but rather shortening the period until registration. Furthermore, a very high discount can raise questions as to why the parties involved are not following their own assessment—the crucial factor is the comprehensibility of the reasoning behind it.

7.3 When does a conservative valuation become a hidden contribution?

The line is crossed where the difference in value is no longer a matter of sound business practice, but rather a gratuitous transfer. Four criteria: Justifiability (derived from measurable volatility and process duration?), consistency (the same standard for all shareholders?), documentation (in writing at the time of assessment?), Proportionality (A figure that a third party would also have estimated?). If the limit is exceeded, the excess amount is a hidden contribution, increases the acquisition costs of the investment, and is recorded in the capital contribution account (Section 27 of the German Corporation Tax Act). Problems only arise if the transaction is not documented.

7.4 How do registry courts handle volatile assets?

There is no uniform picture; reliable data is lacking. Three patterns are reported: Courts with experience in cryptocurrencies examine the traceability of price sources and the power of disposal. Courts without experience often request a valuation certificate, even if the legal situation does not strictly require it. Some courts ask questions from real estate law ("market value appraisal," "freedom from encumbrances") that are not applicable to cryptocurrencies.

Practical advice

The review process runs more smoothly if the valuation method is based on a provision familiar to the court and this is explicitly stated. An analogy to Section 33a Paragraph 1 No. 1 of the German Stock Corporation Act (AktG) is more effective than any technical explanation of blockchain technology. Equally helpful is a one-page summary at the beginning of the documents—what is being contributed, how it was valued, what discount has been applied, and how the power of disposal is proven.

7.5 Which documentation reduces follow-up questions?

  • written derivation of the discount using volatility indicators for the period under review;
  • at least three trading venues with a justification for the selection;
  • Comparison of market value, discount and assessed value in tabular form;
  • Confirmation of the value on the exact date of registration;
  • Explanation of the evaluation method in easily understandable language;
  • Complete evidence package for the power of disposal according to Chapter 5.

7.6 The role of appraisers and auditors

A certificate of value is not legally required for a GmbH (limited liability company) — unlike for an AG (stock corporation) (§ 33 para. 2 AktG). The commercial register can request it. For transactions with a mid-seven-figure volume, less liquid tokens, and if the commercial register lacks experience with cryptocurrencies, it makes economic sense to obtain it from the outset: The costs are significantly less than the risk of a delay of several weeks in a volatile market.

Practical opinion of Finanz Forensik GmbH — Position on the safety margin

A high discount solves the corporate law problem but creates a tax one. A low discount is tax-compliant but risks liability for the difference. There is no value that optimally fulfills both objectives. Anyone who quotes a figure without knowing the duration of the proceedings is working with a rule of thumb instead of an analysis. The only structure that truly resolves the conflict is to forgo the capital measure altogether: Those who contribute the coins to the capital reserve or sell them to the company avoid both a registry court and liability for the difference—and do not have to justify a safety discount.

Key messages
  • Limited liability company law prohibits overvaluation, not undervaluation — a safety margin is permissible.
  • For tax purposes, the fair market value is what counts; the excess amount is a hidden contribution (contribution account § 27 KStG).
  • The most effective lever is not the amount of the discount, but the reduction of the duration of the proceedings.
  • The crucial factor is a verifiable derivation from measured volatility, liquidity, and time risk.
  • Those who want to avoid the conflict of objectives choose the capital reserve or the sale instead of the capital measure.

8 Supervisory law: MiCAR, KMAG and the BaFin license

Regulation (EU) 2023/1114 (MiCAR) for crypto-asset services has been in effect since December 30, 2024. In Germany, it is supplemented by the Financial Market Digitalization Act and the Crypto Markets Supervision Act (KMAG). The national transitional provisions for existing institutions expired on December 31, 2025.

8.1 The crucial distinction: own assets or services for third parties

Legal situation secure As a starting point; the classification in individual cases remains a matter of economic considerations.

The authorization requirement is not based on volume or trading frequency, but rather on whether a service is provided to third parties. A company that exclusively buys, holds, custodys, and sells its own crypto assets does not provide a crypto asset service within the meaning of Article 3(1)(16) MiCAR and therefore does not require authorization under Article 59 MiCAR. The decisive factor is the economic structure—prior agreements, commission models, procurement on behalf of third parties, or the custody of third-party holdings can alter the assessment.

TaskPermit?Classification according to Article 3(1)(16) MiCAR
Buying, holding, and selling your own crypto assetsGenerally, no.No service provision exists as long as there is no customer connection.
Safekeeping of own holdingsGenerally, no.no safekeeping „for customers“ (lit. a)
Custody for third partiesYesCustody and administration for customers (lit. a)
Exchange for customersYesExchange for money / other crypto assets (lit. e, f)
Execution / brokering of customer ordersYesExecution, acceptance and transmission (lit. g, h)
Operation of a trading platform for third partiesYesOperation of a trading platform (lit. d)
Investment advice / Portfolio managementYesConsulting or portfolio management (lit. i, j)
Third-party data transfer servicesYesTransfer services for customers (lit. c)

8.2 The grey area: OTC transactions and repeated brokering

It becomes risky when the company starts trading on behalf of related parties—family members, business associates, or co-shareholders. As soon as third-party crypto assets are held in custody or third-party orders are executed, the offense is committed, regardless of remuneration or designation. The assessment is based on the actual activity, not its name.

Criminal liability without a permit

Providing cryptocurrency services without the required authorization is not merely an administrative offense. Section 46 of the German Banking Act (KMAG) criminalizes violations; the penalty can be up to five years imprisonment or a fine. The German Federal Financial Supervisory Authority (BaFin) can also order the immediate cessation of business operations and liquidation. Anyone even considering working for third parties should have the authorization requirement reviewed in advance by a specialized law firm—self-assessment is not sufficient.

8.3 Family Offices and Pool Structures

If a company pools crypto assets belonging to several family branches or investors, the German Investment Code (Kapitalanlagegesetzbuch) may also apply in addition to the MiCAR authorization requirement, provided that an investment fund is involved. The distinction is complex and must be clarified on a case-by-case basis.

8.4 Money Laundering Law Aspects

A company that exclusively manages its own assets is generally not subject to the German Money Laundering Act (GwG). However, it is subject to the due diligence obligations of others: credit institutions, notaries, and trading platforms require proof of the origin of funds. Prepared documentation of the origin of funds in accordance with Chapter 5 is therefore a practical prerequisite for ensuring that bank accounts and trading accounts remain usable in the long term.

Key messages
  • The licensing requirement is linked to the activity on behalf of third parties, not to volume or trading frequency.
  • Managing only one's own crypto assets is permitted without a license — even with active trading.
  • Authorization is required as soon as third-party crypto assets are held in custody or their orders are executed.
  • Section 46 of the KMAG (German Act on the Promotion of the Sale of Crypto Assets) criminalizes the provision of crypto asset services without authorization.
  • When pooling third-party assets, the German Investment Code must also be examined.

9 Accounting according to German Commercial Code (HGB) and International Financial Reporting Standards (IFRS)

Scope of this chapter

The above statements refer to fungible currency and payment tokens without additional legal positions (Bitcoin, Ether, comparable crypto assets). Different principles apply to utility, security, hybrid, and tokenized securities (Federal Ministry of Finance letter, para. 77); NFTs are expressly excluded (para. 5). Individual case assessment is required in these cases.

9.1 Approach

Prevailing opinion The classification under commercial law is not uncontroversial.

Crypto assets meet the recognition criteria for an asset under Section 246 of the German Commercial Code (HGB): independently marketable, economic benefit. The prohibition on recognition under Section 248 Paragraph 2 Sentence 2 HGB does not apply because they were acquired for consideration. The classification as an intangible asset is the prevailing view under commercial law; the tax authorities take a different approach (paragraph 41: non-depreciable tangible assets). The classification has little impact on disclosure, valuation, and depreciation, but should be explained in the notes to the financial statements.

9.2 Classification as fixed or current assets

The decisive factor is the intended purpose (§ 247 para. 2 HGB): long-term retention → fixed assets, short-term trading/disposal intention → current assets. Paragraph 41 of the Federal Ministry of Finance (BMF) letter: Fixed assets are to be reported under financial assets (§ 266 para. 2 A. III. HGB), current assets under other assets (§ 266 para. 2 B. II. 4. HGB). The reporting under financial assets requires explanation and must be clarified in the notes to the financial statements. The classification must be justified, documented, and consistently maintained.

9.3 rating

Value recoveryReclassification requirement up to acquisition costs (§ 253 para. 5 HGB)Attribution requirement up to acquisition costs

On the balance sheet date, it is recommended to use an average value from several major stock exchanges and to consistently maintain the same methodology. The acquisition cost represents the upper limit of the valuation; a valuation above this amount is not permitted under the German Commercial Code (HGB). Section 256a of the HGB (currency translation) does not apply – crypto assets are not considered foreign currency.

9.4 Comparison of IFRS and US GAAP

Under IFRS, these are predominantly intangible assets (IAS 38); for traders, inventories (IAS 2). IAS 38 introduces the revaluation model (fair value in an active market, recognized in other comprehensive income). US accounting recognizes changes in the value of certain crypto assets in profit or loss at fair value—relevant for German companies primarily in a group context.

The balance sheet volatility effect

The strict lower of cost or market principle and the upper limit on acquisition costs lead to an asymmetrical picture: price losses immediately impact the result, while price gains remain invisible until realized. A price decline on the balance sheet date can trigger a balance sheet loss, even though the assets have grown over the entire period. Anyone working with banks or investors should explain this effect in the notes to the financial statements.

Key messages
  • Fungible currency/payment tokens must be accounted for as assets; their classification as intangible is the prevailing view. This chapter does not apply to NFTs, security tokens, utility tokens, or hybrid tokens.
  • The classification as fixed or current assets depends on the intended holding period and must be documented.
  • There is no scheduled depreciation (no determinable useful life).
  • Current assets are subject to the strict lower of cost or market principle, while fixed assets are subject to a more lenient lower of cost or market principle; acquisition costs are the upper limit.
  • The valuation method for the cut-off date rate must be defined once and maintained consistently.

10 practical examples

Note regarding the examples

The examples are illustrative, not based on specific mandates, and amounts are rounded. They assume: crypto assets held as private property, no commercial activity, no other source of income, and correctly calculated holding periods for each tranche. Where they are based on the identified open legal questions, the following reservation applies. Every real-world scenario requires individual review by a lawyer and tax advisor.

Example 1: €250,000 in Bitcoin, holding period four years. A master craftsman holds BTC worth approximately €250,000 (acquired four years ago for €60,000) and wants to remove the assets from his personal liability sphere. Recommendation: Contribution to the capital reserve. One-year holding period has expired; according to Section 6 Paragraph 1 No. 5 of the German Income Tax Act (EStG), if the holding period exceeds three years, valuation at partial value is possible (book value €250,000 instead of €60,000). Whether this is accepted must be verified for tax purposes beforehand (consider obtaining a binding ruling). No notary, no commercial register, no liability for differences. Effort: minimal.

Example 2 · €1 million, share capital increase desired. An entrepreneur invests €1 million in Ether and increases the share capital to €1,025,000 because a business partner requires minimum capital (acquisition two years ago). Recommendation: Capital increase in kind — the increased share capital is the purpose here. The one-year holding period has expired; the contribution is tax-free. A safety margin should be applied under company law; with a processing time of approximately three weeks, the nominal amount should be significantly below €1 million. Tight scheduling is recommended; consider a valuation certificate. Cost: high.

Example 3 · €10 million, mixed portfolio. Bitcoin, Ether and several illiquid tokens, partly via trading platform, partly in own custody; acquisition period between 6 months and 6 years. Recommendation: Division into tranches. Include holdings outside the one-year period; exclude holdings within the period initially. Expert valuation for illiquid tokens; start with zero for individual positions. Prior forensic analysis of the portfolio's origin. Effort: very high; lead time at least one quarter.

Example 4 · Family office with multiple stakeholders. Three siblings contribute their assets to a joint holding company, with shares later passed on to their children. Recommendation: Capital reserves are not an option (value shift in favor of the other shareholders). Appropriate solutions: capital increase in kind with proportional share allocation or a new company formation with a contribution in kind. Additional costs: gift tax on the subsequent transfer, pooling agreement, key management, and representation. Expenditure: high.

Example 5 · Trading GmbH. An active trader (several hundred transactions/year) establishes a GmbH (limited liability company) to professionalize and retain profits. Recommendation: Sale of the portfolio to the company at market price, with the purchase price held as a shareholder loan. Streamlined, clear acquisition cost basis, later repayment without distribution tax. Prerequisite: meticulous purchase price documentation (arm's length comparison). Additionally: accounting integration and process documentation in accordance with the German Generally Accepted Accounting Principles (GoBD).

Key messages
  • The right approach depends on three factors: duration of the holding period, desired external impact, and number of participants.
  • For holdings exceeding the three-year limit, the capital reserve is regularly the most economical solution.
  • Increasing capital in kind is worthwhile if the increased share capital itself is the purpose.
  • Mixed portfolios should be introduced in tranches according to holding period and liquidity.
  • In the case of multiple shareholders, a contribution without the granting of shares is not possible due to the shift in value.

11 Typical Mistakes

No.MistakeConsequence and avoidance
1Valuation based on a date that is too far in the pastThe value must be valid on the registration date. Remedy: confirmation accurate to the date of registration in addition to a detailed evaluation.
2Price source only from one trading venueVulnerable. Remedy: at least three major trading venues, volume-weighted.
3No safety marginIf the share price falls between the resolution and the registration, there is a risk of liability for the difference (§ 9 GmbHG) in cash.
4Screenshot instead of proof of ownershipNo reliable proof. Remedy: cryptographic signature referencing the transaction plus a test transaction.
5Transfer to an address of the shareholderUnrestricted access cannot be proven. Remedy: newly generated company address with access control.
6Contribution within one year in exchange for sharesTaxable profit (§ 23 EStG) without liquidity. Remedy: Review holding period, change or postpone the investment.
7Open contribution in kind and hidden contribution confusedThe tax consequences are fundamentally different. Remedy: Define the structure in writing beforehand.
8Cash capital increase followed by the purchase of own coinsRisk of hidden contribution in kind (§ 19 para. 4 GmbHG); contribution is deemed not to have been made.
9Trading for family/acquaintances through the companyLicensing requirement; Section 46 of the KMAG (German Commercial Code) criminalizes violations.
10No documentation of originCancelled bank accounts, blocked accounts, inquiries. Remedy: forensic origin analysis beforehand.
11Too long a period between notarization and registrationIncreases valuation risk. Remedy: Schedule appointments in advance and keep them close together.
12No regulations regarding key managementIf the managing director is incapacitated, the company is unable to act. Remedies: multi-signature system, representation arrangements, emergency plan.

Key messages
  • The most common errors do not concern company law, but rather valuation, evidence, and time management.
  • A valuation date that is too far in the past is a classic reason for registry queries.
  • Contribution within the one-year period generates tax without liquidity.
  • The detour via a cash capital increase can be considered a disguised contribution in kind.
  • The lack of documentation of origin only has an impact after the property has been brought into the country — but then it affects society.

Phase 1 · Preliminary examination (weeks 1–2). Inventory (which crypto assets, quantities, acquisition dates/costs); holding period per tranche (one-year period § 23 EStG, three-year limit § 6 para. 1 no. 5 EStG); review exchange transactions (period restarts after each exchange, para. 55); clarify objective; profitability calculation; involve tax advisor and lawyer, obtain binding ruling if necessary.

Phase 2 · Preparation (Weeks 3–5). Define and justify the method of contribution; select the valuation method and trading venues; commission a forensic analysis of origin; set up a custody structure (addresses, access, representation); prepare proof of ownership (signature text, test transaction); coordinate a notary appointment for capital measures; commission a certificate of value for larger volumes.

Phase 3 · Implementation (Weeks 6–7). Document the valuation, derive the discount; provide proof of ownership (sign, test transaction, record); notarize in the case of a capital measure; transfer to the company address (hash, timestamp, confirmations); provide a date-accurate confirmation of value; hand over the complete documentation package to the notary.

Phase 4 · Registration and enrollment (weeks 8–14). Registration with complete documents; prompt response to inquiries; documentation of course development; booking and allocation after registration; procedural documentation (GoBD); updating the deposit account (§ 27 KStG).

Key messages
  • Realistic time required from decision to registration: eight to fourteen weeks.
  • The preliminary review determines the path forward — it is the most important, but most frequently skipped step.
  • Custody arrangements and proof of ownership must be prepared before notarization, not afterwards.
  • There should be as few days as possible between notarization and registration.
  • After registration, the real work begins: ongoing documentation and continuous evaluation.

13 Special Technical Cases

The preceding chapters assume a well-organized portfolio: a personal wallet, complete purchase data, and a liquid market. In practice, this is the exception.

constellationproblemProceed
Stocks on central trading platformsNo private key; authority cannot be proven by signatureBank statements/withdrawal confirmations; transfer to company address before registration; alternatively, re-register the account.
Multiple wallets and UTXO structuresChange outputs make it difficult to assign acquisition data.Wallet-related considerations, continuation of acquisition data for change outputs (para. 56); address directory

Wrapped Token and BridgingEach exchange restarts the time period; allocation requires explanation.Document bridge processes completely, recalculate deadlines for each tranche
Missing/lost acquisition dataAcquisition costs and holding period not verifiableReconstruction from on-chain data and exports; uncovering gaps — tax authorities estimate (§ 162 AO)
Mixed wallets (private + public)Free disposal not verifiableSeparate before contribution: new addresses exclusively controlled by the company.
Multisignature with external signatoriesSociety does not have sole controlSet thresholds so that management can make decisions without third parties; define the circle of signatories.
Tokens with transfer restrictionsMarketability and suitability for contribution in kind are questionable.Check transferability in the protocol and emission conditions; if in doubt, not as a contribution in kind.
Illiquid / manipulation-prone marketsNo reliable market price can be derived.Expert opinion; if no market price is available, start with zero.
Practical opinion of Finanz Forensik GmbH — The timeline depends on the specific cases.

In our experience, the timeline for a contribution is usually determined by these special circumstances, not by the corporate structure. Those who only discover them after the notary appointment lose weeks—and, in the volatile market, valuation certainty. We recommend taking a technical inventory of the portfolio before choosing a course of action: addresses, custody methods, restrictions, exchange transactions, and data gaps. Only then can a realistic approach be assessed.

Key messages
  • Holdings on trading platforms cannot be verified by signature — they must be registered to a company address before registration.
  • Stashed or locked crypto assets are not freely available to management and are unsuitable as contributions in kind.
  • Every exchange — including wrapping and bridging — restarts the disposal period.
  • Mixed wallets must be separated before contribution; the destination address must be solely assigned to the company.
  • Data gaps are revealed, not bridged — otherwise the tax authorities will make an estimate according to § 162 AO.
