Built for KAS crypto tax filing
PIT-38 + 19% flat. Kryptos applies the rules consistently so your filing survives a KAS query.
19% flat capital tax
Single rate applied to net crypto gains. No progressive bracket, no PIT-36 alternative for crypto specifically.
Acquisition cost only
The only deduction Polish law allows. Gas fees, exchange fees, transaction costs rolled into cost basis where the rule permits.
5-year loss carry
Realised losses carry forward for 5 tax years. Kryptos tracks the unused balance so you don't lose deductible losses.
Crypto-to-crypto taxable
Polish law treats swaps as taxable disposals. We compute the PLN-valued gain at each swap moment.
