Portugal taxes short-term cryptocurrency gains at a flat 28% rate under its Personal Income Tax Code Category G, while exempting profits from assets held for more than 365 consecutive days, according to the country's CIRS code. The framework, introduced through the 2023 Orçamento de Estado budget law, ended Portugal's zero-tax era for digital assets by establishing three income categories covering capital gains, passive income, and professional trading activities. Portugal ranked sixth in the Global Crypto-Friendly Nations report published by Global Citizen Solutions, outscoring Germany and Malta in tax favorability. The country has implemented the EU's DAC8 directive through Article 124-A of the CIRS, as amended by Lei 26/2026, requiring crypto service providers to report user transaction data annually to the Autoridade Tributária e Aduaneira by May 31 each year.
Portugal Classifies Crypto Income Under Three IRS Categories
Portugal classifies cryptocurrency income under its IRS (Imposto sobre o Rendimento das Pessoas Singulares) framework through three distinct categories. Category G covers capital gains from selling cryptocurrency for fiat currency or using it to purchase goods and services. Short-term disposals made within 365 days of acquisition are subject to the flat 28% autonomous tax rate, according to Portugal's CIRS code. Long-term gains on qualifying assets held for more than 365 days are exempt from taxation.
Category E covers passive capital income, including staking rewards, lending interest, and yield from DeFi protocols. These earnings are taxed at a flat 28% rate upon receipt, though Portuguese law generally defers taxation of passive income earned in cryptocurrency until the holder converts it to fiat currency. Staking rewards assigned an acquisition value of zero become fully taxable gains upon sale, according to CoinTracking.
Category B applies to professional activity, covering taxpayers whose primary income derives from crypto trading, mining operations, or market-making services. Portugal's income brackets range from 13.25% on the first €7,703 to 48% on income exceeding €81,199, according to CoinTracking. Category B filers may deduct business expenses, including electricity costs, hardware depreciation, and trading losses.
Portugal Exempts Crypto Gains After 365-Day Holding Period
The 365-day holding period exemption applies to cryptocurrency disposals. A taxpayer who purchases Bitcoin in January 2025 and sells it for euros in March 2026 qualifies for the exemption because the holding exceeds 365 days. Portugal uses FIFO (first-in, first-out) accounting to determine which units are disposed of first, as detailed in CoinTracker's Portugal tax guide.
Crypto-to-crypto swaps do not trigger taxable events in Portugal. Exchanging Bitcoin for Ethereum does not create a tax liability. The acquisition cost carries over to the new asset, and the holding period accumulates cumulatively. A taxpayer who holds BTC for 6 months, swaps to ETH, and holds ETH for 7 months has a total holding period of 13 months, qualifying the final sale to fiat for the long-term exemption.
Security-type tokens are excluded from the 365-day exemption. Assets classified as securities under Portuguese law do not qualify for the exemption. Tokens linked to jurisdictions on Portugal's tax blacklist are also excluded from favorable treatment.
Miles Brooks, Director of Tax Strategy at CoinLedger, stated that "a common misconception is that the taxable event occurs at the point you sell your crypto for fiat on an exchange, not the point you withdraw your fiat funds to your bank account," in CoinLedger's guide.
Portugal Requires Annual Modelo 3 Filing Between April 1 and June 30
Portuguese taxpayers must file cryptocurrency transactions in their annual Modelo 3 (IRS) return through the Portal das Finanças between April 1 and June 30 of the following year. Annex G (Anexo G) covers short-term gains taxed at 28%. Annex G1 (Anexo G1) declares long-term gains that qualify for exemption. Zero-tax transactions require reporting, according to Waltio's Portugal guide.
Portugal implemented the EU's DAC8 directive through Article 124-A of the CIRS, as amended by Lei 26/2026 on June 3, 2026. The directive incorporates the OECD Crypto-Asset Reporting Framework (CARF). Covered crypto-asset service providers must report user transaction data to the Autoridade Tributária e Aduaneira by May 31 each year. Tax authorities exchange this information automatically across the EU and partner jurisdictions.
Crypto service providers offering custody services or operating trading platforms must file annual forms detailing client transactions. The Bank of Portugal oversees AML and KYC compliance for all virtual asset service providers (VASPs) operating within Portuguese territory. A 4% stamp duty applies to commissions and fees on transactions conducted by or through VASPs domiciled in Portugal.
EU MiCA Regulation Mandates Licensing by July 1, 2026
Portugal's adoption of MiCA (Markets in Crypto-Assets) regulation aligns its domestic framework with EU-wide transparency, liquidity, and consumer protection standards. The ESMA-mandated MiCA transitional period expires on July 1, 2026. After that date, crypto-asset service providers operating in the EU without a MiCA license must cease operations, according to Global Legal Insights.
The country's NHR 2.0 program, launched in 2024, offers a 20% flat rate on personal income for eligible digital nomads.
