In 1 January 2023, a new regime regarding the taxation of crypto-transactions has entered into force.
A) Capital Gains
Only capital gains deriving from fungible crypto-assets are subject to PIT. Thus, gains from Non-Fungible crypto-assets are excluded.
(i) Fungible crypto-assets that qualify as securities
In general, subject to a 28% rate on the gains (although taxpayers may opt to be subject to progressive tax rates). However, if the holding period is less than 365 days, for taxpayers whose gross income (including such capital gains) is above EUR 78,834, gains are subject to PIT rates up to 48% (plus the additional solidarity tax up to 5%). Losses resulting from crypto-assets located in a blacklisted jurisdiction are not relevant for PIT purposes.
(ii) Fungible crypto-assets that do not qualify as securities
If due by an entity resident in the EU, EEA, or in a jurisdiction with which Portugal has a Tax Convention that includes the exchange of information for tax purposes, these capital gains are not subject to tax if the crypto-asset is held for more than 365 days. If the crypto-asset is held for less than 365 days, such gain will be subject to a 28% PIT rate (although taxpayers may opt to be subject to progressive tax rates).
Crypto for crypto transactions where the initial crypto-asset was held by less than 365 days, are not subject to tax. However, for tax purposes, the acquisition value of the obtained cryptoasset is the acquisition value of the cryptoasset exchanged. In this context the transfer of tax residency abroad may be a tax event (exit tax).
If due by an entity located in jurisdictions other than the jurisdictions referred above or located in a blacklisted jurisdiction are in general subject to a 28% rate on the gains (although taxpayers may opt to be subject to progressive tax rates). Losses deriving from crypto-assets due by an entity located in a blacklisted jurisdiction are not considered for capital gains purposes.
B) Investment Income
Taxation of income deriving from crypto-assets depends on the nature of the remuneration. Remuneration in fungible tokens is taxed as capital gains in the terms explained above. Remuneration in non-fungible crypto-assets or other assets or rights is taxed at 28% PIT rate (or 35% if paid by entities located in blacklist jurisdictions).
C) Business Income
Transactions related with crypto-assets in connection with business activities, including mining or validation of crypto assets transactions through consensus mechanisms are considered as business and professional activities and subject to personal income tax.
If taxpayers have not exceeded in the previous year EUR 200,000 of gross amount of business income, the simplified regime applies. In this case, 15% of the crypto asset transactions gross income is considered taxable. In the case of crypto asset mining 95% of the gross income is considered taxable.
If taxpayers have exceeded EUR 200,000 of gross amount in the previous year, the taxable income is determined according to the accounting records and proof of expenses actually incurred.
Business income is subject to general progressive rates which can go up to 48% plus additional solidarity rate of up to 5%.
D) Gratuitous transfer of crypto-assets
Gratuitous transfer of crypto-assets not deposited in institutions which have a place of business or permanent establishment in Portugal, are not subject to tax.
If the crypto-assets are deposited in an institution which has a place of business or permanent establishment in Portugal, a 10% stamp tax on the market value of the crypto-asset applies if (i) in inter-vivos donations, the donee is domiciled in Portugal; (ii) in mortis causa transactions, the deceased was domiciled in Portugal. Gratuitous transactions between spouses or members of unmarried partners, descendants an ascendant are exempt.
