What is supported

This page shows what capi.tax processes from your Interactive Brokers or Tastytrade export today — and what it does not. Where something is missing, it says what happens instead. It is the same list as on the home page.

Which file

  • Interactive Brokers: the Activity Statement as CSV — see Interactive Brokers.
  • Tastytrade: the transaction export with All Transactions, as CSV — see Tastytrade.

You upload one file per calculation. If you have several accounts, calculate each one separately and add up the KAP figures yourself; the Sparer-Pauschbetrag applies only once across all accounts. Add purchases from earlier years as an opening position.
