Portugal capital gains tax on crypto has long been recognized for its efficiency. Notwithstanding Portugal’s international position among other European countries, recent legislative changes must be considered. This article aims to clarify the current personal income tax framework governing cryptocurrency transactions in Portugal as of 2025, ensuring that individual taxpayers are well-informed about the current situation.
Taxation of Cryptocurrency in Portugal
The Portuguese tax system classifies income into different categories, depending on how it is generated, each with distinct implications for cryptocurrency-related activities:
- Capital Income (Category E) pertains to passive income streams, such as earnings from staking or lending cryptocurrencies. Capital income is considered to be the fruits and other economic benefits, whatever their nature or denomination, whether pecuniary or in kind, arising directly or indirectly from assets, property, rights or legal situations of a movable nature, as well as their respective modification, transfer or termination, except for gains and other income taxed in different categories, especially those resulting from any forms of remuneration arising from transactions relating to crypto assets. For this category, income from crypto-asset transactions is exempt from withholding tax. Therefore, capital income is subject to taxation at a special rate of 28%, and residents may choose to include it. However, income is only taxed in the year it is earned if:
- a) Received in cash or kind (except crypto assets) or
- b) They are received by taxable persons or owed by any person or entity when one or the other is not resident for tax purposes in another Member State of the European Union or the European Economic Area or in another State or jurisdiction with which an international double taxation convention, bilateral or multilateral agreement providing for the exchange of information for tax purposes is in force.
- If the income takes the form of crypto assets, there is no taxation at that time (attributing the acquisition value of the delivered crypto-assets to the received crypto assets), but only when there is an effective onerous sale in cash or in kind (except crypto assets), in which case they are taxed as capital gains.
- Capital Gains (Category G): Profits realized from the capital gains derived from the sale of cryptocurrencies (conversion into fiat) are treated as capital gains. The tax treatment varies based on the holding period:
- Short-Term Holdings: Cryptocurrencies held for less than one year are taxed at a flat rate of 28% on the gains.
- Long-Term Holdings: Assets held for more than one year are exempt from capital gains tax, promoting long-term investment strategies.
- Self-Employment Income (Category B): Income derived from professional activities involving cryptocurrencies, such as issuance of crypto assets, including mining or validating transactions through consensus mechanisms. This type of income is taxed progressively, with rates ranging from 14.5% to 53%, depending on the total reported worldwide income (this does not consider social security contributions).
Key Considerations for Cryptocurrency Investors
- Holding Period: Investors should consider holding their crypto assets for over a year to benefit from tax exemptions on capital gains.
- Record-Keeping: Maintaining detailed FIFO records of all cryptocurrency transactions per trading platform is crucial for accurate tax reporting and compliance.
- Tax Residency: Tax obligations are influenced by your residency status. Non-resident taxpayers may be subject to exit tax depending on their crypto-assets hold period for the year they become non-residents.
