Cómo declarar criptomonedas en Portugal
Portugal ceased to be a total crypto paradise in 2023, but it maintains a very strong incentive: if you hold your crypto assets for more than 365 days, capital gains from their sale are exempt from IRS.

The 365-day threshold
Sales of crypto assets held for less than a year are taxed at 28% in category G, with the option to opt for progressive tax rates. After 365 days of ownership, capital gains are exempt.
The exemption does not apply to crypto assets considered securities or to operations carried out by residents in privileged tax jurisdictions.
Staking, mining, and professional activity
Passive remunerations such as staking are taxed in category E at 28%. Mining and trading carried out regularly and professionally fall into category B, with business activity rules and specific coefficients.
If you trade very frequently, the Autoridade Tributária can reclassify your gains as professional activity, which completely changes the taxation.
Before filing: have your history in order
The first step to a proper tax declaration is to download the complete transaction history from each platform you use. MiCA-licensed exchanges often provide ready-to-use annual reports, which significantly simplifies the filing process.
