Built for AEAT crypto tax filing

Every AEAT position on crypto, applied so your Renta and informativa returns line up.

Progressive savings rates

19% to 28% applied to your annual net gain across the AEAT brackets. No flat rate; the right bracket per disposal.

Crypto-to-crypto taxable

Spain treats every swap as a permuta and taxes the gain. Kryptos applies this consistently so your declared gain matches what an inspector would compute.

FIFO across wallets

First-in-first-out applied portfolio-wide, not per-exchange. The AEAT view, not the spreadsheet shortcut.

Modelo 721 + 720

Foreign crypto exchange holdings (721) and general foreign assets (720) populated automatically when you cross the thresholds.

Every form the AEAT accepts

Modelo 100 (declaración Renta)
Modelo 721 (crypto holdings abroad)
Modelo 720 (foreign assets)
