Portugal Capital Gains Tax for Expats

Is Capital Gains Tax in Portugal 28% or 50%?

These figures describe different things. A 28% rate commonly applies to a resident individual’s taxable securities gains under the ordinary rules. For property, 50% is normally the share of the net gain included in taxable income, which then follows progressive IRS rates. It is not a 50% tax rate.

The answer depends on what you sell, your tax residence, holding period and any qualifying relief. This guide separates property, shares and foreign disposals so you can identify the calculation and records your return needs.

Capital Gains Rules at a Glance for 2026

Property: generally 50% of the net gain enters progressive IRS taxation, subject to statutory exceptions and any qualifying exclusion.

Securities: the ordinary autonomous rate is 28%. A resident can often elect aggregation; specified securities held for less than 365 days must be aggregated when taxable income, including that balance, reaches the top IRS band.

Unlisted micro and small companies: a qualifying positive balance can receive 50% inclusion under the statutory company-size definition. This is not a rule for all private-company shares.

Longer-held investments: eligible traded securities and open-ended collective-investment holdings can receive 10%, 20% or 30% exclusions according to their holding period. The asset and statutory exceptions must be checked.

Property Gains for Residents and Non-Residents

For a Portuguese resident individual, the ordinary rule includes 50% of the net property gain in taxable income. For example, a EUR 100,000 net gain would normally add EUR 50,000 before applying the relevant IRS calculation. The resulting tax depends on other income, deductions and relief; it is not reliably calculated by halving one marginal rate.

Since 2023, a non-resident’s Portuguese property gain also generally uses 50% inclusion and progressive IRS rates. Worldwide income is considered to determine the applicable rate under article 22. This does not make all foreign income taxable in Portugal for a non-resident.

Article 43 contains exceptions, including specified properties supported by substantial non-repayable public aid and sold within the statutory ten-year period. Business-use property and ownership through a company require a different review.

Reinvestment Relief: Main Home and the 2026 Rental Route

Reinvestment relief concerns the sale proceeds after repayment of the loan used to acquire the sold property, not just the gain. Buying another property does not automatically exempt the sale.

For the main-home route, the sold property must meet the permanent-home and tax-address conditions. The normal requirement is 12 months before the sale or, if earlier, before the reinvestment, subject to statutory exceptional circumstances. Reinvestment must occur within 24 months before or 36 months after the sale, in a qualifying permanent home in Portugal, the EU or an EEA state with tax-information exchange.

Declare the reinvestment intention and amount in the sale-year return. A purchased replacement normally must become the main home within 12 months after reinvestment, with the required tax address. Construction, enlargement or improvements follow their own registration and occupation deadlines. Partial qualifying reinvestment gives proportional relief.

A separate route applies to qualifying residential-property sales from 1 January 2026 to 31 December 2029, with reinvestment in Portuguese housing for rent within statutory rent limits. Its requirements include the reinvestment window, a letting contract normally within six months, at least 36 months of letting in the first five years and compliance with rent and retention rules. The relevant post-reinvestment clocks run from reinvestment or, if later, the sale. It is not the main-home replacement route.

Purchase Costs, Improvements and Inflation Adjustments

Build the property gain from the acquisition value, any eligible monetary correction, the disposal value and allowable expenses. Under article 51, documented enhancement costs incurred in the previous 12 years can qualify, together with necessary, actually incurred acquisition and disposal expenses. Not every repair, furnishing or invoice is an allowable enhancement.

Keep the deed, tax and registry charges, qualifying agency or legal costs and improvement invoices linked to the specific property and transaction. Public aid and periods of business use can restrict the amounts allowed.

Under article 50, acquisition values of qualifying real-property rights held for more than 24 months can be adjusted using the applicable official coefficient. The same article also covers qualifying equity interests; inflation adjustment is not limited to property.

Shares and Funds: Holding Periods, Rates and Cost Basis

The ordinary 28% securities rate applies to the taxable balance, not gross sale proceeds. Establish acquisition lots, fees, corporate actions and the relevant category before comparing autonomous taxation with aggregation. Specified short-held securities require aggregation when the conditions in article 72(14) are met.

For eligible securities admitted to trading and holdings in open-ended collective-investment undertakings, article 43(5) excludes 10% of the balance for assets held more than two but less than five years, 20% for five to less than eight years, and 30% for at least eight years. The rule also adjusts a negative balance and excludes specified cases. Do not apply it indiscriminately to every investment or fund.

Qualifying equity interests held for more than 24 months can receive monetary correction under article 50. This differs from the holding-period exclusion. Property reinvestment relief does not carry across to ordinary share sales.

Preserve broker statements, lot history and fee evidence. A foreign broker does not by itself make a gain foreign-source. Use the foreign-income guide for reporting and the crypto guide for the separate cryptoasset rules.

Track Reinvestment from the Sale to the Return

Before selling, identify the relief route and calculate the sale proceeds, acquisition-loan repayment and amount to reinvest. Record any qualifying investment already made within the pre-sale window.

After completion, track the remaining purchase, construction, tax-address or letting conditions with their actual dates. The relevant deadlines depend on the chosen route; a sale date alone is not the whole timetable.

Declare the required intention and amounts in the sale-year return and keep the subsequent evidence with that calculation. If reinvestment is partial, delayed or followed by a change of use, review the relief and any corrective filing instead of leaving the original assumption unchanged.

Scenario Comparison: Property vs Securities

Assume a Portuguese resident sells a home and a share portfolio in the same year. The following comparison concerns Portuguese personal income tax; it does not calculate a combined tax bill.

Before filing, reconcile each disposal’s dates, proceeds, basis and fees to its documents. Keep a separate line for the Portuguese treatment and any foreign tax or refund. Apply relief only after the conditions are documented; do not offset unlike categories simply because the assets were sold together.
