The tax office is evaluating data from Bitcoin.de – many crypto investors are receiving letters as a result. Learn about the risks of a tax audit and how to respond legally

Mass Data Request: Why Bitcoin.de Had to Hand Over Customer Data to the Tax Office

In recent years, the tax office has issued mass data requests (Sammelauskunftsersuchen) to the crypto exchange Bitcoin.de. The goal: the handover of customer data. This data has already been delivered. Now the ball is in the hands of the tax administration, which is processing, analyzing, and making the information available to the respective local tax offices.

The result: More and more investors are receiving mail from the tax office, often with very specific questions about their transactions. At the latest now, it is clear: you yourself are in the spotlight of the tax audit.

How the Tax Administration Evaluates Crypto Data and Forwards It to Local Tax Offices

The process at a glance:

  1. Mass data request to Bitcoin.de — The exchange is obligated to transmit customer data, e.g., trading volumes, deposits and withdrawals, wallet movements.
  2. Data processing by the tax administration — The transmitted raw data is centrally evaluated, organized, and split into individual datasets per taxpayer.
  3. Forwarding to local tax offices — The respective tax offices receive the data of their taxpayers and compare them with previously filed tax returns.
  4. Letter to the taxpayer — Affected investors are contacted directly and must provide information — often under short deadlines and with the threat of criminal tax consequences.

Mail from the Tax Office: What Does the Letter Mean for Crypto Investors?

Anyone who receives mail from the tax office must react quickly. Usually, it's not about general questions but about specific transactions and tax returns.

The Biggest Risks for Crypto Investors During a Tax Audit

Anyone who falls under the scrutiny of the tax office quickly faces serious consequences. Especially with cryptocurrencies like Bitcoin, even small discrepancies can have far-reaching effects — from back tax payments to criminal investigations. A tax audit on cryptocurrencies poses the following risks in particular:

  • Comparison of crypto gains with tax returns: If crypto gains were not reported or only partially reported, this is immediately noticed.
  • Risk of criminal tax proceedings: If discrepancies are discovered, criminal tax proceedings can be initiated very quickly.
  • Loss of the possibility of voluntary disclosure: Anyone who only reacts when the authority already has all the data often forfeits the chance for a penalty-free correction.
