Stricter documentation obligations: The new BMF letter makes you serious
As Jana Bauer, Managing Director of the Federal Association of Wage Tax Association (BVL), told the German Press Agency, the tax authorities recently significantly tightened the requirements for the detection. The decisive detail: Investors have to document all transactions in detail – even if in the end there are no taxes.

Bitpanda is the Bafin-licensed crypto broker from Austria and the official crypto partner of FC Bayern Munich. Create your account with just a few clicks and benefit from 0% deposit and withdrawal fees.
This tightened regulation is based on the updated BMF letter dated March 6, 2025, which replaces the previous provisions from 2022. The 34 -page document makes it clear: whether profit or loss, whether taxable or tax -free – the business must generally be notified to the tax office and be proven accordingly.
The reason for tightening lies in the frequent use of foreign trading platforms. The BMF thereby justifies extended obligations to cooperate in the event of abroad according to Section 90 (2) Tax Code. Investors must inform the complete facts independently and procure all the necessary evidence – a significant shift in the burden of proof to the taxpayers.
1-year period and 1,000-euro limit: When tax
Basically, profits from cryptocurrency sales in Germany remain tax -free if more than a year has passed between the purchase and sales date – the so -called speculation period. However, if the tokens are sold within this period at a profit, it must be taxed with the personal tax rate.
The exemption limit of 1,000 euros per year is crucial for all private sales transactions. If this limit is only exceeded by one euro, the entire profit must be taxed from the first euro. If the profits stay below, there are no taxes.
Particularly important: Even if there are no taxes, investors must be able to prove when asked by the tax office that the speculation period or the exemption limit was observed. Without the appropriate documentation, this proof becomes impossible.
Screenshots, wallet addresses and tax reports: What is considered evidence
The tax office accepts various evidence for the required documentation. The recognized evidence includes plausible evidence of the wallet addresses as well as the names of the trading platforms for every transfer – for example by screenshots of the wallets or transaction overviews of the exchanges used.
As can be seen from Ecovis KSO’s contribution, tax reports from tools can also be used, but only under certain conditions: the reports must be complete and plausible. Negative stocks, missing history or unexplained deposits and withdrawals are not acceptable and must be corrected manually.
The rules in foreign platforms are particularly strict. Here, investors have to obtain all relevant data and documents themselves. If they are lost – for example because a platform is spit or through hacker attacks – the tax office can appreciate the values to the detriment of taxpayers. A situation that can quickly become expensive, since estimates are often significantly higher than the actual profits.
