What is the mais-valias tax rate in Portugal?

Listed securities are generally taxed at a flat 28% rate. For Portuguese real estate, 50% of a positive net gain is generally aggregated with other income and taxed at progressive IRS rates. Since 2023 this aggregation treatment also applies to non-residents, whose worldwide income is considered when determining the applicable rate.

Does the 50% property-gain inclusion apply to non-residents?

Yes. Under the current regime, both residents and non-residents generally include 50% of a positive net gain from Portuguese real estate in taxable income. Documented acquisition and disposal costs and qualifying improvement expenses may reduce the gain. This calculator asks for the applicable progressive rate because it cannot derive it without the taxpayer’s other worldwide income.

How is crypto taxed in Portugal?

Since January 2023, cryptocurrency gains are taxable. Assets held for under 365 days are taxed at 28%. Crypto held for more than 365 days is fully exempt from capital gains tax under current law. Mining and staking income is treated differently (professional income or Category B).

Are property gains reinvested in a primary residence exempt?

Yes. Gains from selling your Portuguese primary residence can be exempt if the proceeds are reinvested in another primary residence in Portugal or an EU/EEA country within 36 months (or 24 months before the sale). This calculator does not model the reinvestment exemption — consult a tax advisor if this applies to you.

What is the NHR regime and does it affect capital gains?

The Non-Habitual Resident (NHR) regime historically taxed certain foreign-source income at 0% or 10%. The original NHR regime closed to new applicants at end-2023; a new IFICI incentive replaced it from 2024. Portuguese-source capital gains are generally still taxed at standard rates under NHR. This calculator uses standard resident and non-resident rates.

Can I deduct capital losses against gains?

Yes. Capital losses on securities can be offset against gains on securities in the same category (Category G) in the current year, and unused losses can be carried forward up to five years. Property losses cannot offset securities gains and vice versa. Enter a net gain after losses in this calculator.

Estimate only. For property, the calculator taxes 50% of a positive net gain at the IRS rate you enter; it does not derive that rate from worldwide income. It does not model reinvestment exemptions, indexation coefficients, mandatory aggregation of some short-held securities, or solidarity surcharges. Consult a certified accountant for personal advice.

Summary

Portugal taxes capital gains (mais-valias) under the IRS (Imposto sobre o Rendimento das Pessoas Singulares) system. For both residents and non-residents, 50% of a net gain on Portuguese real estate is generally aggregated with other income and taxed at progressive IRS rates; the exact rate depends on worldwide taxable income. Listed shares and other securities are generally taxed at a flat 28% rate. Qualifying crypto gains are generally taxed at 28% when held for under 365 days and may be exempt after 365 days. This calculator estimates tax on a single disposal and lets property sellers enter an applicable IRS rate.
