Built for AT crypto tax filing
Portugal's regime since 2023 favours patient holders. Kryptos applies the 365-day test consistently so you don't miss tax-free disposals.
365-day holding rule
Hold over 365 days? Disposal is exempt. Under 365? Taxed at 28%. We track the holding period per acquisition lot so the cutoff lands accurately.
Crypto-to-crypto exempt
Swap one crypto for another and AT does not treat that as a taxable event. We track the cost-basis transfer without firing a tax event.
Investor vs trader
Regular trading activity reclassifies you into self-employment (Anexo B). We surface the signals AT considers so you classify correctly.
Mining + staking
Income at receipt, taxed under category B if professional or category E if passive. Each treatment applied where the AT guidance points.
Every form the AT accepts
