The cryptocurrency landscape is evolving rapidly, and governments worldwide are adapting their tax frameworks to regulate this digital asset class. Portugal, known for its favorable tax environment, introduced a specific cryptocurrency taxation regime effective January 1, 2023—providing clarity for investors, traders, and businesses operating in the country. This guide offers a detailed overview of how crypto assets are taxed in Portugal, helping you stay compliant while optimizing your tax position.
Understanding the Categories of Crypto Income
Portugal’s Personal Income Tax Code (Código do IRS) classifies cryptocurrency income into three main categories: passive income (Category E), capital gains (Category G), and self-employment income (Category B). Accurately identifying which category applies is essential for correct tax reporting.
Passive Income from Crypto Investments
Passive income includes rewards such as staking or interest earned from lending crypto, when paid in fiat currency and without transferring ownership of the underlying digital asset. This type of income is taxed at a flat rate of 28%.
However, if the reward is received in cryptocurrency (e.g., staking payouts), it may still be considered taxable income. In such cases, the value at the time of receipt is assessed and may fall under different categories—potentially subjecting it to progressive tax rates if classified as employment or self-employment income.

Capital Gains from Selling Cryptocurrencies
One of Portugal’s most attractive tax features is its treatment of long-term capital gains. Profits from selling cryptocurrencies held for more than 365 days are completely tax-exempt. This exemption applies only if the sale results in fiat currency (e.g., EUR).
Short-term gains—those from assets held less than 365 days—are subject to a flat tax rate of 28%. However, if a taxpayer opts for global aggregation (englobamento), these gains may instead be taxed at progressive rates ranging from 14.5% to 53%, depending on total annual income.
An important exception applies to security or investment tokens, which are treated as financial securities regardless of holding period and are always subject to taxation upon disposal.
Key Rules for Capital Gains Reporting:
- FIFO Method: The "First In, First Out" rule is used to determine the acquisition cost of sold assets.
- Loss Offset: Capital losses can be used to offset capital gains in the same or future years—unless the loss occurs in a jurisdiction classified as a tax haven by Portugal.
- Exit Tax: If an individual ceases to be a Portuguese tax resident, a deemed "exit tax" of 28% applies to unrealized gains on crypto assets, calculated based on market value minus acquisition cost (using FIFO).
Self-Employment Income from Mining and Validation
Individuals engaged in crypto mining, node operation, or transaction validation may earn income classified under Category B (self-employment). This includes rewards received in cryptocurrency for contributing computing power or validating blocks.
Such income is subject to progressive taxation between 14.5% and 53%, based on total earnings. Additionally:
- A 5% flat-rate expense deduction is allowed for mining-related operational costs.
- When mining equipment or generated crypto is sold, a 95% expense deduction applies, significantly reducing taxable profit.

Furthermore, self-employed individuals must issue invoices for their services where applicable and may be required to register with Social Security (Segurança Social), paying mandatory contributions on top of income tax obligations. VAT registration may also be triggered depending on the nature and scale of activity.
General Rules for Cryptocurrency Taxation in Portugal
Beyond income categorization, several overarching principles govern how digital assets are treated under Portuguese tax law.
Taxation Timing and Exchange Transactions
Taxes on crypto are generally deferred until a taxable event occurs—such as converting crypto to fiat or using it to purchase goods or services. Simple exchanges between cryptocurrencies (e.g., BTC to ETH) do not trigger immediate taxation if they fall under capital gains or passive income rules.
However, when such exchanges involve self-employment activities (e.g., running a decentralized exchange), they may be subject to business income rules.
Donations and Gift Tax
Transferring crypto as a gift incurs a 10% stamp duty (Imposto do Selo). Alternatively, if facilitated through a crypto service provider, a reduced rate of 4% may apply.
Exemptions include:
- Gifts between spouses, registered partners, parents, and children.
- Donations valued under €500.
NFTs and Digital Collectibles
As of now, NFTs are not subject to taxation in Portugal when held or transferred—provided they are not classified as investment or security tokens. However, if an NFT generates income (e.g., royalties from secondary sales), that revenue may be taxable under relevant categories such as capital gains or self-employment.
Security or utility tokens that function like traditional securities or offer access to services may be taxed differently, emphasizing the need for proper asset classification.
Key Considerations for Effective Crypto Tax Planning
To ensure compliance and optimize your tax strategy in Portugal, consider the following factors.
Correct Classification of Assets and Income
Misclassifying crypto activities can lead to incorrect reporting and potential penalties. For example:
- Staking rewards might look like passive income but could be seen as self-employment if part of an organized business.
- Receiving crypto as payment for freelance work falls under professional income, not capital gains.
Always assess the economic substance and intent behind each transaction.
Impact of Double Taxation Agreements (DTAs)
Portugal has signed numerous Double Taxation Agreements (DTAs) with countries worldwide. These agreements help prevent income from being taxed twice—especially relevant for expats or digital nomads earning crypto income abroad.
While the new crypto tax rules don’t alter DTA applicability, they interact with existing frameworks like the Non-Habitual Resident (NHR) regime, which previously offered tax exemptions on foreign-sourced crypto income. Although recent changes have limited NHR benefits for crypto, understanding how DTAs apply remains crucial for cross-border tax planning.
Recordkeeping and Compliance
Maintaining accurate records of all transactions—including dates, values in EUR, wallet addresses, and purpose—is vital. The Portuguese Tax Authority (Autoridade Tributária) may request detailed reports during audits.
Use crypto tax software to automate tracking and generate compliant reports—especially important given the complexity of FIFO calculations and multi-year loss carryforwards.
