How are share capital gains taxed in Portugal?

Gains on shares and securities for residents are taxed at a flat 28% IRS rate (taxa especial), with an option to include them in your overall income (englobamento) if that is more favourable. Losses can offset gains in the same category, subarea, subject to holding-period rules for low-tax jurisdictions.

How is property capital gains tax calculated in Portugal?

For real property (mais-valias), only 50% of the gain is taxable. That half is added to your other income and taxed at the progressive IRS marginal rates, not a flat rate. Acquisition costs, improvement costs in the last 12 years, and an inflation correction coefficient reduce the gain.

Is there an exemption when I sell my main home in Portugal?

Yes. The gain on your primary residence can be fully exempt if you reinvest the sale proceeds (net of any outstanding mortgage) into another main home in Portugal or the EU/EEA, generally within 24 months before or 36 months after the sale. Partial reinvestment gives partial relief.

What rate do non-residents pay on Portuguese gains?

Non-residents are generally taxed on Portuguese-source gains, historically at a flat 28% (or with the 50% property reduction following EU case law). Treaty provisions and residency status matter, so confirm your position; this tool models the resident rules.

This Portugal capital gains tax calculator handles the two main cases under the IRS rules: a flat 28% on gains from shares and securities, and the mais-valias rule for real property, where only 50% of the gain is added to your income and taxed at progressive marginal rates — with relief if you reinvest a main-home sale. Pick the asset, enter your figures, and see the tax and your net proceeds.

How it works

The gross gain is proceeds − acquisition cost (your purchase price plus buying costs).

Shares / securities: the whole gain is taxed at the flat 28% rate. Losses in the same category offset gains first.

Real property (mais-valias): only 50% of the gain is taxable. That half is added to your other taxable income and taxed at the progressive IRS brackets, so the marginal rate depends on your total income. If the disposal is your primary residence and you reinvest the proceeds into another main home, the gain is exempt in proportion to the reinvestment.

Example

A €20,000 share gain is simply 20,000 × 28% = €5,600 tax, leaving €14,400 net. A €60,000 gain on a second property has a €30,000 taxable half; added on top of, say, €25,000 of other income it is taxed across the IRS brackets, producing a noticeably lower effective rate than 28% at modest income levels.

Notes

This is a simplified estimate. It omits the inflation-correction coefficient, deductible improvement costs from the last 12 years, and the detailed reinvestment-timing tests. The IRS marginal brackets used are the mainland 2024 scale. Confirm your figures with an accountant or the Autoridade Tributaria — Portuguese property gains can be materially reduced by the items left out here.
