Free crypto tax tools

A set of quick, no-login tools for the everyday questions crypto investors ask before they file. Each runs in your browser, nothing is uploaded, and none of them need an account. For the full picture across all your wallets and exchanges, the crypto tax calculator ties everything together.

These tools give estimates and general information, not tax advice. Rules differ by country and change over time, verify against your tax authority or a qualified advisor.

Why they are free

These tools answer one question each, well, and they cost nothing because they are how most people first meet CryptaTax. When a single trade turns into a year of activity across several venues, the full report picks up where the tools leave off, reconciling transfers, tracking cost basis across wallets and producing figures you can file.
