Portugal's Crypto Tax Haven Era Is Over — But It's Still Pretty Great
Since 2023, short-term crypto gains are taxed at 28%. But hold for 365+ days and your gains are still tax-free. The catch? Swapping tokens resets the clock. We track it all.

Rules you need to know.
The 365-Day Rule
Portugal’s biggest advantage. Hold crypto for more than 365 days and the capital gain is completely tax-free. But this is a cliff: sell at day 364 and you pay 28%. Sell at day 366 and you pay nothing. The holding period starts when the crypto enters your wallet.
Swaps Reset the Clock
Exchanging one crypto for another (e.g., BTC → ETH) resets the 365-day holding period for the new token. The swap itself isn’t immediately taxed, but you lose your accumulated holding time. This is the most common trap for active traders who think they’re building toward the long-term exemption.
Staking/Lending Income Has No Long-Term Exemption
Unlike capital gains, passive crypto income (staking, lending, yield farming) is taxed at 28% as Category E regardless of holding period. There’s no way to make this tax-free.
You Must Report Tax-Free Gains
Even if your gains qualify for the 365-day exemption and are completely tax-free, you MUST still declare them in Anexo G1 of your Modelo 3. Failing to report exempt gains can trigger penalties.
Sound familiar?
We trace every token’s full lifecycle through swaps and transfers, calculate accurate holding periods using FIFO, and separate tax-free long-term gains from taxable short-term gains.
Yes, you report on Anexo J (foreign income). We prepare all the necessary forms with EUR values at the time of each transaction.
Staking and yield income is taxed at 28% regardless of holding period. We calculate the Category E income separately from your Category G capital gains.
