Whitepaper
From the private key to the balance sheet. Volatility, proof of control, and choosing the right path are challenging.
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.
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.
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.
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.
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.
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.
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.
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.
| Away | Notary / Registry | Valuation | Tax consequences for shareholders | Typical use |
|---|---|---|---|---|
| Sale to the GmbH | no | no (comparison with other countries) | Sale; tax-free after 1 year | Standard procedure for a liquid company |
| Contribution in kind upon incorporation | Yes | Yes (report) | Sale (exchange-like) | Restructuring from the very beginning |
| Contribution in kind during capital increase | Yes | yes (register) | Sale (exchange-like) | Strengthening of share capital, external impact |
| Loan to the GmbH | no | no | no sale | Interim solution, short-term |
| Deposit into the reserve fund | no | no | Deposit, usually not a sale | Tax-optimized transfer after holding period |
| trust model | no | no | depending on the design | Special cases, high need for consultation |
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.
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).
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.
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.
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.
| document | Content and function | Who signs — with what responsibility? |
|---|---|---|
| Report on in-kind contributions | Explanation of the circumstances relevant for the valuation (§ 5 para. 4 GmbHG) | All shareholders; liability for the accuracy of the information |
| Insurance § 8 para. 2 GmbHG | Confirmation that the deposit has been made and is available for use | Management; criminally liable under Section 82 of the German Limited Liability Companies Act (GmbHG). |
| Technical Assessment Facility | Price sources, methodology, volatility, derivation of the discount | Technical service provider; data basis, no expert responsibility. |
| Certificate of Value | Confirmation that the value has reached its nominal value | Auditor / Expert; professional liability |
| Expert opinion | Independent valuation with justification of methodology | Expert; liability for the expert opinion result |
| Blockchain proof | Signature protocol, test transaction, transaction hashes, custody confirmation | technical 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.
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.
| method | Proceed | fitness |
|---|---|---|
| Key date price | Price of a defined trading venue at a defined time | Only for very short periods of time; susceptible to criticism |
| Daily average | Volume-weighted average of a trading day across multiple exchanges | A 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 opinion | Valuation by auditors or experts | For 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.
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.
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.
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.
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.
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.
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.
| form of safekeeping | Description | Assessment for the contribution |
|---|---|---|
| Hardware wallet (cold storage) | Offline storage of the keys, company safe | Suitable; put access and representation rules in writing. |
| Multisignature wallet | Multiple keys required, e.g., 2 of 3 | Recommended for transactions of six figures or more; reflects the four-eyes principle. |
| Approved Provider (CASP) | Custody by a CASP with MiCAR approval | Suitable; check the registration status in the ESMA register |
| Shareholder's wallet | Coins remain at the previous address | Unsuitable; free disposal by management not verifiable. |
| Account on trading platform | The holdings remain in a stock exchange account. | Only to a limited extent; the account must be in the company's name. |
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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:
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).
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.
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.
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 registration | Bitcoin / Ether | Established altcoins | remark |
|---|---|---|---|
| up to 1 week | 10 – 15 % | 20 – 25 % | Tight schedule, lowest risk |
| 2-4 weeks | 20 – 25 % | 30 – 40 % | Typical practice case |
| over 4 weeks | 30 – 40 % | higher in individual cases | Shortening 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.
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.
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.
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.
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.
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.
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.
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.
| Task | Permit? | Classification according to Article 3(1)(16) MiCAR |
|---|---|---|
| Buying, holding, and selling your own crypto assets | Generally, no. | No service provision exists as long as there is no customer connection. |
| Safekeeping of own holdings | Generally, no. | no safekeeping „for customers“ (lit. a) |
| Custody for third parties | Yes | Custody and administration for customers (lit. a) |
| Exchange for customers | Yes | Exchange for money / other crypto assets (lit. e, f) |
| Execution / brokering of customer orders | Yes | Execution, acceptance and transmission (lit. g, h) |
| Operation of a trading platform for third parties | Yes | Operation of a trading platform (lit. d) |
| Investment advice / Portfolio management | Yes | Consulting or portfolio management (lit. i, j) |
| Third-party data transfer services | Yes | Transfer services for customers (lit. c) |
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.
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.
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.
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.
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.
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.
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.
| Fixed assets | Current assets | |
|---|---|---|
| Access assessment | Acquisition costs | Acquisition costs |
| When depositing | Value according to § 6 para. 1 no. 5 EStG or fair market value | accordingly |
| Scheduled depreciation | No — no determinable service life | no |
| Follow-up assessment | modified lower of cost or market principle (§ 253 para. 3 sentence 5 HGB) | strict lower of cost or market principle (§ 253 para. 4 HGB) |
| Value recovery | Reclassification 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.
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 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.
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).
| No. | Mistake | Consequence and avoidance |
|---|---|---|
| 1 | Valuation based on a date that is too far in the past | The value must be valid on the registration date. Remedy: confirmation accurate to the date of registration in addition to a detailed evaluation. |
| 2 | Price source only from one trading venue | Vulnerable. Remedy: at least three major trading venues, volume-weighted. |
| 3 | No safety margin | If the share price falls between the resolution and the registration, there is a risk of liability for the difference (§ 9 GmbHG) in cash. |
| 4 | Screenshot instead of proof of ownership | No reliable proof. Remedy: cryptographic signature referencing the transaction plus a test transaction. |
| 5 | Transfer to an address of the shareholder | Unrestricted access cannot be proven. Remedy: newly generated company address with access control. |
| 6 | Contribution within one year in exchange for shares | Taxable profit (§ 23 EStG) without liquidity. Remedy: Review holding period, change or postpone the investment. |
| 7 | Open contribution in kind and hidden contribution confused | The tax consequences are fundamentally different. Remedy: Define the structure in writing beforehand. |
| 8 | Cash capital increase followed by the purchase of own coins | Risk of hidden contribution in kind (§ 19 para. 4 GmbHG); contribution is deemed not to have been made. |
| 9 | Trading for family/acquaintances through the company | Licensing requirement; Section 46 of the KMAG (German Commercial Code) criminalizes violations. |
| 10 | No documentation of origin | Cancelled bank accounts, blocked accounts, inquiries. Remedy: forensic origin analysis beforehand. |
| 11 | Too long a period between notarization and registration | Increases valuation risk. Remedy: Schedule appointments in advance and keep them close together. |
| 12 | No regulations regarding key management | If the managing director is incapacitated, the company is unable to act. Remedies: multi-signature system, representation arrangements, emergency plan. |
| risk | Probability. | impact | Countermeasure | Responsible |
|---|---|---|---|---|
| Price collapse decision → Registration | high | Liability for differences in cash (§ 9 GmbHG) | Time-based tightening, derived discount, value confirmation | Partner, Attorney |
| Unclear proof of ownership/disposition | medium | Inquiry, delay | Signature with documentary reference, test transaction, custody confirmation | technical service provider |
| Entry within the holding period | medium | Tax without liquidity | Check holding periods for each tranche, tranche by tranche / change of route | tax advisor |
| peculiarity in the middle origin | medium | Blocked bank/stock market accounts | Origin analysis in advance, written report | technical service provider |
| Custody error / key loss | low–medium | Loss of assets | Multi-signature, access/representation rules, emergency plan | Management |
| Hidden contribution in kind (§ 19 IV GmbHG) | low | The deposit is considered not to have been made. | No cash increase with purchase; define the terms in advance. | lawyer |
| Misclassification under supervisory law | low | Prohibition, criminal proceedings (§ 46 KMAG) | Check permit requirements before any model extension | Attorney at Law, Management |
| Non-recognition of the deposit valuation | open | Subsequent taxation, changed book value | Binding ruling pursuant to Section 89 Paragraph 2 of the German Fiscal Code (AO). | tax advisor |
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).

The preceding chapters assume a well-organized portfolio: a personal wallet, complete purchase data, and a liquid market. In practice, this is the exception.
| constellation | problem | Proceed |
|---|---|---|
| Stocks on central trading platforms | No private key; authority cannot be proven by signature | Bank statements/withdrawal confirmations; transfer to company address before registration; alternatively, re-register the account. |
| Multiple wallets and UTXO structures | Change outputs make it difficult to assign acquisition data. | Wallet-related considerations, continuation of acquisition data for change outputs (para. 56); address directory |
| Stashed or locked crypto assets | No free disposal at the time of registration | Remove the block before registration; otherwise, contribution in kind is not possible — sale/later contribution |
| Wrapped Token and Bridging | Each exchange restarts the time period; allocation requires explanation. | Document bridge processes completely, recalculate deadlines for each tranche |
| Missing/lost acquisition data | Acquisition costs and holding period not verifiable | Reconstruction from on-chain data and exports; uncovering gaps — tax authorities estimate (§ 162 AO) |
| Mixed wallets (private + public) | Free disposal not verifiable | Separate before contribution: new addresses exclusively controlled by the company. |
| Multisignature with external signatories | Society does not have sole control | Set thresholds so that management can make decisions without third parties; define the circle of signatories. |
| Tokens with transfer restrictions | Marketability 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 markets | No reliable market price can be derived. | Expert opinion; if no market price is available, start with zero. |
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.
The appendix describes what information the technical documentation should contain — expressly not legal contract templates, but content requirements for the technical documentation.
| document | Required information |
|---|---|
| Description of the deposited item | Trade name and network; quantity with all decimal places; receiving address; date of the quantity statement. Do not use the phrase "Bitcoin worth X". |
| Proof-of-Ownership Text | Company name and registered office; document number and date; description of the transaction; originating address; name of the signatory. So specific that it only applies to this specific transaction. |
| Wallet assignment confirmation | List of all addresses with role (outbound, destination, change); custody form; date of address creation; confirmation that the destination address is new and exclusively assigned to the company. |
| Transaction proof | Full hash; sender/receiver address; amount; block timestamp (UTC); block height; number of acknowledgments; block explorer used. |
| Technical Assessment Facility | Trading venues with justification; price type; observation period; volatility indicators; derivation of the discount; comparison of market value/discount/applied value. |
| Value update | Rate on the registration date from the same sources; quantity; resulting value; comparison to the nominal amount; date and signatory. |
| Source of Funds Report | Traceability depth and methodology; analysis tools and data status; results of the check for sanctioned addresses, mixing services, reported entities; identification of restrictions. |
| Custody and access log | Storage method and location; signature threshold for multi-signature systems; authorized users and representatives; emergency plan; date of last review. |
This list does not replace a legal review of the resolutions and deeds. Its purpose is to ensure that the technical attachments are complete before the notary submits the application. It has proven effective to send the attachments to the notary's office in advance and to document in writing the responsible party for each document.
