Capital Gains on Selling Portuguese Property
The exit tax most buyers don’t think about until they’re selling. How CGT works in Portugal, what residents pay vs non-residents, and the legal ways to reduce it.
Updated April 2026Why CGT Matters Before You Buy
Portugal’s capital gains tax (CGT) on property is calculated on the difference between your sale price and your acquisition cost, adjusted for inflation and improvement spend. The framework is fair on paper but the rates and the rules differ sharply between residents and non-residents — and the way you structure your purchase today shapes the bill at sale.
Most buyers focus on IMT and stamp duty going in and forget about CGT going out. That’s a mistake: a 10% capital gain on a €500,000 property over five years is a real number, and the tax on it can be the difference between a healthy investment and a flat one. Understanding the rules upfront also opens up legitimate planning — particularly the reinvestment exemption for primary residences.
This guide covers the framework, the rates, the inflation adjustment, the reinvestment exemption, and the documentation you need to keep from day one to minimise your eventual tax.
The Capital Gains Calculation
The mechanics of arriving at the taxable gain.
Sale price minus acquisition cost
Start with the sale price (less agent commission and legal fees on the sale). Subtract the original acquisition cost (purchase price plus IMT, stamp duty, notary, and registration fees on the way in).
Inflation adjustment (coeficiente de desvalorização da moeda)
If you’ve owned the property for more than 24 months, the acquisition cost is uplifted by an inflation coefficient set annually by the Autoridáde Tributária. The longer you’ve held it, the larger the uplift — reducing the taxable gain.
Eligible improvements
Documented improvement spend in the last 12 years is added to the acquisition cost. Renovation work, extensions, structural improvements, energy upgrades — with proper receipts and licences. Routine maintenance doesn’t count.
Resulting figure: the taxable gain
Sale proceeds minus inflation-adjusted acquisition cost minus eligible improvements = the gain. This is the figure tax is calculated on.
Keep every receipt from day one
The reason your CGT bill at sale will be lower than the headline calculation suggests is the improvements deduction. Reno work, extensions, even some upgrades. But you can only deduct what you can prove with proper invoices showing your NIF and (where relevant) câmara permits. Treat receipts and invoices as part of the property’s file from purchase to sale.
Two Very Different Tax Regimes
Where you’re tax-resident at the time of sale matters enormously.
Portuguese tax residents
Only 50% of the gain is added to your taxable income for the year. That income is then taxed at progressive IRS rates (13.25%–48% in 2026). For a high-rate taxpayer with a substantial gain, the effective rate can reach 24%.
Non-residents
The full 100% of the gain is taxed at a flat 28%. No 50% reduction, no progressive scale, no allowances. Significantly heavier than the resident position for most cases.
EU/EEA non-resident election
Non-residents from EU and EEA countries can elect to be taxed under the resident rules (50% of gain at progressive rates) instead of the flat 28%. Worth modelling both options before filing — the election is per tax year and per disposal.
Sale year vs occupation history
Tax residency is assessed at the time of sale, not at purchase. A non-resident who becomes resident before selling may benefit from the resident regime. Conversely, a resident who emigrates and sells later faces the non-resident regime. Timing matters.
| Status | Taxable proportion | Tax rate | Notes |
|---|---|---|---|
| Tax resident | 50% of gain | 13.25–48% (progressive) | Reinvestment exemption available for primary home |
| Non-resident (default) | 100% of gain | Flat 28% | No reinvestment exemption |
| Non-resident (EU/EEA election) | 50% of gain | 13.25–48% (progressive) | Optional, per tax year |
The Reinvestment Exemption (Residents)
Tax residents selling their primary home can defer or eliminate CGT by reinvesting in another primary home.
What qualifies
The property sold must be your primary residence (habitação própria permanente) at the time of sale. The reinvestment must also be in a primary residence — in Portugal or elsewhere in the EU/EEA — for you and your household.
Reinvestment window
You can reinvest sale proceeds (less any outstanding mortgage on the sold property) within 24 months before or 36 months after the sale. Most sellers use the post-sale window.
Partial reinvestment
If you reinvest only part of the proceeds, the exemption applies pro rata. The unreinvested portion is taxed normally.
Pension and over-65 reinvestment
Recent rules allow tax residents over 65, or in retirement, to reinvest sale proceeds into qualifying pension products (PPR) or insurance-linked vehicles instead of another property — preserving the exemption while freeing up capital.
How to Reduce Your Eventual CGT Bill
Practical steps from day one of ownership.
Document every improvement
Every renovation invoice with your NIF, every câmara permit, every architect bill. Keep them in one folder for the life of the property.
Time the sale around residency
If you’re close to becoming or ceasing tax resident, the timing of the sale can shift the bill by tens of thousands. Discuss with a tax advisor before listing.
Consider holding longer
The inflation adjustment uplifts your acquisition cost more the longer you hold. After 10 years, the cumulative uplift is substantial — meaningfully reducing the taxable gain.
Check the EU election (if non-resident)
EU/EEA non-residents should always model both the flat 28% and the resident-rules election before filing. The right choice depends on the size of the gain and your other income.
Plan reinvestment carefully
If you’re a tax resident planning to upsize or move, structure the sale and reinvestment to use the exemption fully. Buying first and selling later is often easier than the reverse.
Get tax advice before listing — not after
The choices that reduce CGT (residency status, election, reinvestment, timing) all need to be set up before the sale, not after. A two-hour consultation with a Portuguese tax advisor before you list can save tens of thousands. We’d strongly recommend it on any sale over €200,000.
