Germany Proposed Taxing Half of Every Undocumented Crypto Sale, and the Paperwork Just Became Worth Real Money

By Omar aka Crypt0 · Sep 26, 2026

Germany's Federal Ministry of Finance has drafted a crypto tax rule with a number that concentrates the mind. Taxpayers who sell digital assets and are unable to show credible proof of what they paid for them would face a 50 percent substitute assessment basis, meaning the tax is calculated on half of the sales proceeds rather than on actual gains. Buy the coin, lose the receipt, and the state assumes your profit.

The draft is early, still in interdepartmental coordination, but the mechanics are already clear. The tax agency would treat purchases as if they were made after December 31, 2026. Assets bought before that date keep the existing one year holding exemption, where profits from sales after a year of ownership go untaxed. Crypto providers would start withholding capital gains tax on sales from January 1, 2028, which creates the documentation problem. Investors routinely buy on one platform and sell on another, so pinning down the original price is genuinely hard.

The sharpest criticism came from Patrick Hansen, Senior Director for EU Strategy and Policy at Circle, the largest MiCA regulated stablecoin issuer. On social media, Hansen warned that the rule lands hardest on ordinary investors, people who are unable to technically document their acquisition costs in a clean way and who in recent years sometimes bought with little profit or even at a loss. His line deserves a direct quote, the implicit assumption that prices double looks shaky when Bitcoin trades below last year's price and many altcoins have underperformed. Taxing half the proceeds can mean paying taxes on gains that exist only on the agency's worksheet.

Legal analysis backs the concern. Dr. David Hötzel of the law firm Poellath points out the 50 percent figure remains open to revision, and he agrees it creates real liquidity risks. Coins moving from self custody wallets or foreign platforms to German exchanges would be caught, with the provisional deduction applying up front. His summary is precise, the protection of existing holdings effectively depends on reliable documentation.

There is a larger pattern here. Germany issued about a quarter of the 244 MiCA licenses the EU granted by June, making it the bloc's licensing capital, and tax policy remains a national matter even under a harmonized rulebook. The ministry projects the reform adding about €160 million in revenue by 2028 and €350 million a year by 2031. Europe is building a two track system, smooth licensing at the EU level and sharp teeth at the national level.

For readers, the takeaway is practical and surprisingly positive. Documentation just became one of the most valuable assets in a portfolio. A clean record of every purchase date, price, and platform is the difference between paying tax on real gains and paying tax on half of everything that hits your account. Germany's draft makes the case for treating your receipts like cold storage, labeled, backed up, and kept forever.
