In short: In Austria, yes, completely automatically. In Germany and the rest of the world, we support you with ready-made reports, but you are responsible for filing the actual tax return yourself.
🇦🇹 Austria
Yes, 21bitcoin simplifies tax compliance. Since January 1, 2024, Austrian crypto brokers are legally obliged to automatically deduct capital gains tax (KESt) – and that's exactly what we do for you. For profits from the sale of Bitcoin, we withhold the 27.5% KESt and remit it directly to the tax authorities. You don't have to declare your Bitcoin profits yourself in your tax return and don't have to worry about anything.
🇩🇪 Germany
In Germany, we do not automatically deduct any taxes – this is not legally mandated here. However, we make filing your tax return as easy as possible for you: With a single click, you can export your account statement and your complete transaction history as a PDF or CSV. Good to know regarding German law: Profits are tax-free after a holding period of more than one year (§ 23 EStG). If you sell earlier, profits are subject to your personal income tax rate, provided the tax-free allowance of €1,000 per year is exceeded.
🌍 Rest of the World
Outside of Austria, we do not automatically deduct any local taxes. However, you can always access your account statements and tax reports (PDF & CSV) for any period, which you can use for your tax declaration according to the respective national rules.
Note: This information is for general guidance only and does not constitute tax advice. For your individual situation, please consult a tax advisor.
