KryptoSteuer

KryptoSteuer is an AI-adjacent crypto tax calculator that helps German cryptocurrency investors estimate capital gains, losses, and staking income under German tax law (§ 23 EStG). It runs entirely in the browser: your transaction data is processed locally and is not uploaded to an external server, so you can model a tax position without creating an account. The trade calculator applies the FIFO method to work out gains and losses, while a separate staking-rewards calculator tracks income from staked coins. A holding-period tracker flags when a position crosses Germany's 1-Jahres-Regel (the 12-month threshold after which a sale is tax-free), which is one of the harder rules to track by hand. You can enter trades manually or bulk-import them from a CSV file directly in the browser. It supports Bitcoin, Ethereum, Solana, XRP and other major assets. The vendor is explicit that the output is non-binding ("unverbindlich") and meant only as a first orientation, so it complements rather than replaces a Steuerberater for formal filing. For German hobbyist and retail investors who want a quick, private read on their crypto tax exposure, this crypto tax calculator covers the core FIFO and holding-period math at no cost.
