Collective information request: Why Bitcoin.de had to provide customer data to the tax office

In recent years, the tax office has made collective requests for information to the crypto exchange Bitcoin.de. The aim: to hand over customer data. This data has already been provided. Now the ball is in the tax authorities' court to process and analyze the information and make it available to the individual 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 this point at the latest, it is clear that you yourself are the focus of the tax audit.

How the tax authorities evaluate crypto data and pass it on to the local tax offices

The process at a glance

  1. Collective information request to Bitcoin.de - The exchange is obliged to transmit customer data - e.g. trading volumes, deposits and withdrawals, wallet movements.
  2. Data preparation by the tax authorities - The transmitted raw data is evaluated centrally, sorted and broken down into individual data records per taxpayer.
  3. Forwarding to the tax offices of residence - The respective tax offices receive the data of their taxpayers and compare it with tax returns that have already been submitted.
  4. Letter to the taxpayer - Affected investors are contacted directly and must provide information - often with short deadlines and 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. This is because it is usually not about general questions, but about specific transactions and tax returns.

The biggest risks for crypto investors during a tax audit

Anyone who is targeted by the tax authorities quickly faces serious consequences. With cryptocurrencies such as Bitcoin in particular, even minor discrepancies can have far-reaching consequences - from back taxes to criminal investigations. The following are the main risks associated with a tax audit on cryptocurrencies:

  • Reconciliation of crypto profits with tax returns: If crypto profits were not declared or only partially declared, this is immediately apparent.
  • Risk of criminal tax proceedings: If discrepancies are discovered, criminal tax proceedings can be initiated very quickly.
  • Loss of the opportunity to self-disclose: Anyone who only reacts when the authorities already have all the data often forfeits the opportunity to make a subsequent declaration exempting them from prosecution.
