Proof of Origin and Reporting Requirements for Cryptocurrencies

Trading in Bitcoin, Ethereum, and other digital assets has created new opportunities for investors. However, as values rise and these assets become increasingly integrated into the traditional financial system, regulatory pressure is also growing. Banks and online platforms/exchanges for buying, selling, transferring, and holding cryptocurrencies (BISON/Coinbase/Binance/Bitpanda) require rigorous proof of the source of funds for cryptocurrencies, and tax authorities are conducting increasingly thorough audits. As a highly specialized law firm specializing in commercial and tax criminal law, we will guide you safely through this complex environment, protect your assets, and shield you from serious legal consequences.

The Problem: Increasing Requirements from Banks and Tax Authorities

If you want to realize significant profits from crypto trading and transfer them to your bank account, you’ll face two key challenges:

1. The Bank’s Obligation to Prevent Money Laundering: Under the Money Laundering Act (GwG), your bank is required to verify the source of large incoming funds. Standard account statements are often insufficient for this purpose. The bank must receive a plausible explanation for the origin of your crypto assets.
2. Tax Treatment of Your Gains: In most cases, crypto gains are taxable. The tax office expects you to report them completely and accurately on your tax return.

If these issues are not carefully addressed, you will expose yourself to significant risks.

The Risks: What Happens Without Complete Documentation?

1. Suspicion of Money Laundering

If you cannot provide plausible proof of the source of your crypto profits to the bank, the consequences are serious:

• Report to the FIU: The bank is legally required to file a suspicious activity report with the Financial Intelligence Unit (FIU).
• Account Suspension: Your accounts may be suspended temporarily or permanently.
• Criminal Investigation: A report from the FIU often leads to the initiation of a criminal investigation on suspicion of money laundering—even if your profits are entirely legal. In this case, the burden of proof lies with you.

2. Consequences Under Criminal Tax Law

Regardless of the money laundering issue, the tax office checks whether all profits have been properly reported for tax purposes.

• Suspicion of Tax Evasion: Missing or incomplete information on a tax return can quickly give rise to suspicion of tax evasion.
• Severe Penalties: In addition to having to pay back taxes, you may face substantial fines or even a prison sentence.
• Search and Seizure: A preliminary investigation often begins with a search of your home and business premises by the tax investigation unit.
