Just like volatile stock prices, the falling or rising prices of crypto assets are discussed in the daily news. However, unlike disposals of shares, the income tax treatment of disposals of value-fluctuating crypto assets is not explicitly regulated now.
With a circular dated May 10, 2022, the German Federal Ministry of Finance (Bundesfinanzministerium; BMF) for the first time commented on “Individual questions on the income tax treatment of virtual currencies and other tokens.” This was comprehensively revised by a BMF circular dated March 6, 2025, on “Individual questions on the income tax treatment of certain crypto assets” and thereby closes a number of open questions regarding the tax classification of digital assets.
In the current draft federal budget 2027, the federal government announced a far-reaching reform: from 2027, profits from crypto assets are to be taxed at a flat rate of 25% plus solidarity surcharge regardless of the holding period. Crypto assets acquired by December 31, 2026 are reportedly to enjoy grandfathering protection and to remain subject to the previous one-year holding period. Furthermore, an automatic tax withholding by exchanges and banks is planned from 2028. Numerous questions remain open in this regard; the reform proposal is also not yet coordinated within the CDU/SPD coalition. We will monitor further developments and keep you continuously informed. Our article explains the current legal situation regarding the income tax treatment of crypto assets.
According to the BMF circular dated March 6, 2025, a crypto asset is the digital representation of a value or a right that can be electronically transferred and stored using Distributed Ledger Technology (DLT) or a similar technology.
A distributed ledger is an information store that is shared across a number of DLT nodes and synchronized among the DLT nodes by a consensus mechanism. It is designed so that entries are tamper‑proof and immutable and only allow additions. In a so-called blockchain all confirmed transactions are continuously recorded in numbered order.
The structure and development of crypto assets are diverse. For income tax treatment, the actual economic function and design of the crypto asset are therefore decisive - regardless of the designation under the Markets in Crypto‑Assets Regulation (MiCAR).
Against this background, crypto assets can be distinguished as follows:
A wallet is generally required to receive, hold and transfer crypto assets. The function of the wallet is similar to a key ring. It stores the private and public keys with which the market participants operate.
Public key
Serves as the receiving address for transactions, comparable to an IBAN or an email address.
Private key
Is known only to the owner and serves as a password or for generating digital signatures for transactions, comparable to the PIN for a bank account or the password for an email account.
In addition to acquisition against fiat currency (a government‑issued means of payment) or by exchange for other crypto assets, crypto assets can - according to the BMF circular dated March 6, 2025 - also be acquired or generated by the following methods:
The BMF circular dated March 6, 2026 additionally contains explanations on inventory determination and the associated methods (UTXO and accounting).
The BMF circular dated March 6, 2025 provides, depending on the circumstances of the individual case, for the following types of income in connection with crypto assets:
Explanations on income from employment (Section 19 EStG) and on wage tax withholding in connection with the granting of crypto assets in the context of an employment relationship are no longer included in the BMF circular dated March 6, 2025 compared with the circular of May 10, 2022.
Fundamentally, for the taxation of crypto assets it is decisive whether the related activity is either commercial (Section 15 EStG) or constitutes private asset management (Section 22 no. 2 in conjunction with Section 23 EStG). Neither the BMF circular dated March 6, 2025 nor current fiscal-court case law provide a conclusive and clear distinction between the types of income.
Whether and to what extent repeated purchasing and selling of crypto assets is to be classified as private asset management or as a commercial activity is determined according to the criteria for commercial securities and foreign exchange trading. According to these criteria, transactions - even if they attain a substantial volume and extend over a longer period - are initially not to be attributed to commercial activities; however, this applies only as long as the purchase and sale occur in the ordinary form between private persons.
Particularly in critical borderline cases and given the still lacking customary practices in crypto trading, correct classification will remain difficult in many cases. The German tax administration therefore continues to rely on general tax rules, whereas, for example, Austria has had its own statutory provision for taxation of crypto assets since March 1, 2022.
Excursus: assessment as an economic asset
With its judgment of February 14, 2023 (case no. IX R 3/22) the German Federal Fiscal Court (Bundesfinanzhof; BFH) confirmed the BMF’s view that individual crypto assets constitute (other) assets within the meaning of Section 23 (1) sentence 1 no. 2 sentence 1 EStG for the taxation of profits from private disposals. On the basis of their market price - which can regularly be determined via trading platforms and lists - they are also amenable to independent valuation.
The BFH’s principles on classifying crypto assets as assets are significant across income types and are therefore also relevant for the commercial sphere; they can be allocated either to fixed financial assets under financial investments or to current assets under other inventory items. For a cash-basis profit and loss statement, the assets are to be included in the ongoing registers to be kept under Section 4 (3) sentence 5 EStG.
We describe the income tax specifics in more detail below:
As already stated above, unlike the BMF circular of May 10, 2022, the BMF circular dated March 6, 2025 no longer contains explanations on income from employment (Section 19 EStG) and on wage tax withholding. Therefore, for the income tax assessment in connection with the granting of crypto assets in an employment relationship, the general rules must be applied: corresponding receipts generally constitute employment income and are therefore subject to income tax pursuant to Section 19 (1) sentence 1 no. 1 EStG as well as to wage tax withholding under Section 38 (1) EStG.
A subsidized or free transfer of crypto assets by the employer to the employee can constitute either a cash benefit (Section 8 (1) EStG) or a non-cash benefit (Section 8 (2) EStG). Cash benefits include, among others, legal tender valid in the country or payments in a commonly used, freely convertible and domestically tradable foreign currency. Non-cash benefits are all receipts not in cash. While currency or payment tokens such as Bitcoin and Ether can, for example via appropriately issued vouchers, constitute a cash benefit, utility or security tokens can only constitute a non-cash benefit.
A non-cash benefit is generally to be valued at the usual final prices at the place of supply reduced by customary discounts (Section 8 (2) sentence 1 EStG). For simplification, it may also be set at 96% of the supply value. As the usual final price at the place of supply, the market price of a trading platform or a web-based list may be used for crypto assets. A non-cash benefit is disregarded if it does not exceed EUR 50 in total in the calendar month (Section 8 (2) sentence 11 EStG).
Notice
It remains to be seen whether the BMF will comment again on granting crypto assets within the framework of an employment relationship. This would be welcome to create legal certainty for employers in the wage tax withholding procedure. In the meantime, obtaining a wage tax ruling (Lohnsteueranrufungsauskunft) under Section 42e EStG is recommended.
Taxpayers must prepare their tax return to the best of their knowledge and belief pursuant to Section 150 (2) of the Fiscal Code of Germany (Abgabenordnung; AO) and cooperate in fact-finding under the general rules in Sections 90 et seq. AO; tax-relevant facts must be disclosed fully and truthfully and known pieces of evidence must be indicated.
For crypto asset transactions, public on-chain data alone are not sufficient, since direct conclusions about the identity of individual taxpayers are not possible due to pseudonymization. Therefore, additional documents and information from the taxpayer are required for income tax substantiation; plausible and internally consistent tax reports can be used for this purpose. If the tax bases cannot be determined or calculated due to lack of comprehensible documents and information, the tax authority will estimate them pursuant to Section 162 (2) AO.
Notice
Taxpayers often transact via more than one wallet or portal, so the documents and information to be presented to the tax authority must be compiled from a number of sources. The quality of information provided by trading platforms varies widely, especially because providers operate globally and so far few to no regulatory reporting requirements have applied. If the substantiation maintained by the taxpayer is comprehensible and plausible, it will generally be accepted as a basis for tax assessment.
To avoid disputes with the tax authority, it is therefore advisable to provide all evidence from the various platforms with the tax returns and to document the determined tax bases. Unfortunately, the BMF circular dated March 6, 2025 does not specify the exact requirements. These will likely include minimum information on purchases and sales including respective prices, holding periods, number and names of crypto assets as well as the profit with indication of acquisition costs and disposal proceeds. The Fiscal Court of Nuremberg judgment of January 22, 2025 (case no. 3 K 760/22) shows very illustratively what possibilities and sources of error already exist in compiling these tax bases and how - with effort - a meaningful and, in principle, acceptable determination of income for the tax authority can be achieved.
