If you're considering moving to Portugal, understanding the country's tax system — particularly expat capital gains tax in Portugal — is one of the most important financial steps you can take before, during, and after your relocation. Portugal has long been a top destination for expats thanks to its climate, cost of living, and quality of life, but its tax rules on capital gains can catch newcomers off guard.

Whether you're selling a home in your country of origin, disposing of an investment portfolio, or planning to sell Portuguese real estate down the line, this Portugal expat tax guide will walk you through everything you need to know about capital gains tax for the 2025/2026 tax year.

What Is Capital Gains Tax in Portugal?

Capital gains tax (known as mais-valias in Portuguese) is a tax levied on the profit you make when you sell or dispose of an asset for more than you paid for it. In Portugal, capital gains are not taxed under a separate regime — they are generally incorporated into your overall income tax return (IRS), though they may be taxed at special rates depending on the asset type.

Capital gains in Portugal can arise from the sale of:

  • Real estate (property)
  • Shares and securities (stocks, bonds, funds)
  • Intellectual property
  • Business assets
  • Cryptocurrency (increasingly relevant for 2025/2026)

For expats moving to Portugal, the most common scenarios involve selling a property abroad before relocating, selling Portuguese property after settling in, or disposing of an investment portfolio.

Portugal Capital Gains Tax Rates for 2025/2026

Portugal's capital gains tax rates differ depending on whether you are a tax resident or a non-resident, and on the type of asset being sold.

Capital Gains on Real Estate

For tax residents of Portugal:

  • Only 50% of the net capital gain from selling real estate is added to your taxable income.
  • This 50% is then taxed at Portugal's progressive income tax rates, which range from 13.25% to 48% (plus a solidarity surcharge of up to 5% on very high incomes).
  • Effectively, this means the maximum tax on the full real estate capital gain is approximately 26.5% for the highest earners, though many expats will pay significantly less.

For non-residents:

  • The capital gain on Portuguese real estate is taxed at a flat rate of 28% on the full gain.
  • However, non-residents who are EU/EEA citizens can elect to be taxed under the same rules as residents (the 50% inclusion method with progressive rates), which may result in a lower tax bill.

Practical Example: Imagine you purchased an apartment in Lisbon for EUR 250,000 and sell it for EUR 400,000. Your gross capital gain is EUR 150,000. As a tax resident, only EUR 75,000 (50%) is added to your other taxable income. If your marginal tax rate is 37%, the tax on the gain would be approximately EUR 27,750. As a non-resident taxed at the flat 28% rate on the full EUR 150,000, you'd owe EUR 42,000 — a significant difference.

Capital Gains on Shares, Securities, and Financial Investments

For tax residents:

  • Gains from selling shares, bonds, investment funds, and other securities are generally taxed at a flat rate of 28%.
  • Alternatively, you can opt to include these gains in your overall taxable income (englobamento), which may be beneficial if your marginal income tax rate is below 28%.

For non-residents:

  • Gains from Portuguese securities may be taxed at 28%, but many gains (especially on shares in listed companies) are exempt if the non-resident is from a country that has a double taxation agreement (DTA) with Portugal.

Capital Gains on Cryptocurrency

As of the 2023 tax year onward (continuing into 2025/2026), Portugal taxes capital gains on cryptocurrency that is held for less than one year at the flat rate of 28%. Crypto assets held for more than one year are exempt from capital gains tax. This was a major change from the prior regime where crypto was largely untaxed, and it's an important consideration for expats moving to Portugal with significant crypto holdings.

How Tax Residency Affects Your Capital Gains Liability

Your tax residency status in Portugal is the single most important factor in determining how — and how much — you'll be taxed on capital gains. Getting this wrong is one of the most common mistakes expats make.

When Are You a Tax Resident in Portugal?

You are generally considered a tax resident in Portugal if:

  1. You spend more than 183 days in Portugal during a calendar year (these do not need to be consecutive).
  2. You have a habitual residence in Portugal as of December 31 of the relevant year (e.g., you own or rent a home that suggests you intend to live there permanently).

Once you become a tax resident, Portugal taxes you on your worldwide income, including capital gains from assets located anywhere in the world. This is a critical point: selling shares on a US stock exchange or a property in the UK while you are a Portuguese tax resident means Portugal may tax that gain.

Non-Residents: What Gets Taxed?

If you are not a Portuguese tax resident, Portugal only taxes capital gains on assets located in Portugal — most commonly Portuguese real estate and shares in Portuguese companies.

Timing Your Asset Sales

Many expats planning a move to Portugal strategically time asset disposals. For instance, if you plan to sell a property or a large stock position, doing so before you become a Portuguese tax resident may be advantageous, as Portugal would not tax a gain on a non-Portuguese asset earned while you were not yet resident. However, you must still comply with the tax rules in your country of origin.

The Non-Habitual Resident (NHR) Regime: What's Changed for 2025/2026?

Portugal's Non-Habitual Resident (NHR) tax regime was one of the most attractive tax incentives for expats globally. It offered a flat 20% income tax rate on certain Portuguese-source income and broad exemptions on foreign-source income for a period of 10 years.

End of the Classic NHR Regime

The Portuguese government announced the end of new NHR applications effective from 2024. If you registered as an NHR before the cutoff, you continue to enjoy the benefits for the remainder of your 10-year period. However, new arrivals in 2025 and beyond generally cannot access the classic NHR regime.

The New Tax Incentive for Scientific Research and Innovation (IFICI)

To replace the NHR, Portugal introduced the IFICI regime (Incentivo Fiscal à Investigação Científica e Inovação) starting in 2024, with full application in 2025/2026. Key features:

  • Available to individuals who become Portuguese tax residents and were not resident in the previous five years.
  • Targeted primarily at professionals in scientific research, technology, innovation, and certain other qualifying activities.
  • Offers a flat 20% tax rate on qualifying Portuguese-source employment and self-employment income.
  • Foreign-source income, including capital gains, may be exempt from Portuguese tax in certain cases, depending on the specific provisions and the applicable DTA.

The IFICI regime is more restrictive than the old NHR, so not all expats will qualify. If you're moving to Portugal in 2025 or 2026, it's essential to check whether your professional profile meets the eligibility criteria.

Impact on Capital Gains for Former NHR Holders

Expats who are still within their 10-year NHR window may benefit from exemptions on foreign-source capital gains, provided the gains could be taxed in the source country under an applicable DTA (or under the OECD Model Tax Convention rules). This means, for example, that a capital gain from selling property in France might be exempt in Portugal under NHR if France has the right to tax it.

For those under the new IFICI regime or under standard tax residency rules, foreign capital gains are generally taxable in Portugal as part of your worldwide income, subject to relief under double taxation agreements.

Double Taxation Agreements: Avoiding Being Taxed Twice

One of the biggest concerns for expats is being taxed on the same capital gain in both Portugal and the country where the asset is located. Portugal has an extensive network of double taxation agreements (DTAs) with over 80 countries, including the United States, United Kingdom, Canada, Germany, France, Brazil, and many others.

How DTAs Work for Capital Gains

The typical DTA follows the OECD Model Tax Convention, which generally provides:

  • Real estate gains: The country where the property is located has the primary right to tax the gain. Portugal will then either exempt the gain or grant a tax credit for the foreign tax paid.
  • Shares and securities: The country of residence (Portugal, if you're a resident) usually has the right to tax the gain, though there are exceptions for shares in companies whose value is primarily derived from real estate.
  • Other assets: Generally taxable only in the country of residence.

Practical Steps to Avoid Double Taxation

  1. Determine which DTA applies between Portugal and the country where the asset is located.
  2. Check the specific article on capital gains (usually Article 13 of the DTA).
  3. Claim relief in your Portuguese tax return — either as an exemption or a foreign tax credit.
  4. Keep documentation of any foreign taxes paid, as Portuguese tax authorities (Autoridade Tributária) will require proof.

If you're selling property or investments in your home country while resident in Portugal, failing to claim DTA relief is a costly and surprisingly common mistake.

Key Exemptions and Deductions That Can Reduce Your Tax Bill

Portugal offers several important exemptions and deductions that can significantly reduce your capital gains tax liability.

Primary Residence Exemption (Reinvestment Relief)

If you sell your primary residence (habitação própria e permanente) in Portugal, you may be fully exempt from capital gains tax, provided:

  • You reinvest the entire sale proceeds in another primary residence in Portugal, the EU, or the EEA within 36 months after the sale (or 24 months before).
  • The new property must also be used as your primary residence.
  • If you only reinvest part of the proceeds, a proportional exemption applies.

This exemption is one of the most valuable tax benefits for expats who are upgrading, downsizing, or relocating within Portugal or the EU.

Reinvestment from Foreign Primary Residence

Expats who sell their primary residence abroad and reinvest in a primary residence in Portugal may also qualify for this exemption, provided they were resident in the foreign country at the time of sale and become Portuguese residents. The rules can be complex, so professional advice is recommended.

Allowable Deductions Against Capital Gains

When calculating your taxable capital gain on real estate, you can deduct:

  • Acquisition costs (including transfer tax/IMT, stamp duty, notary fees, and legal fees paid on purchase)
  • Improvement costs (documented capital improvements made in the last 12 years, but not routine maintenance)
  • Selling costs (real estate agent commissions, energy certificates, etc.)
  • Inflation adjustment: The original purchase price can be adjusted using official monetary correction coefficients (coeficientes de desvalorização da moeda), which reduce the taxable gain to account for inflation over the holding period.

Example: You bought a house for EUR 200,000 in 2010, spent EUR 30,000 on documented improvements, and paid EUR 15,000 in acquisition costs. After applying the inflation coefficient (let's say 1.15 for 2010), your adjusted acquisition cost becomes approximately EUR 247,250 (EUR 200,000 × 1.15 + EUR 30,000 + EUR 15,000 adjusted). If you sell for EUR 400,000, your taxable gain is approximately EUR 152,750 rather than EUR 200,000 — a significant reduction.

Filing and Payment: What Expats Need to Know

Filing Deadlines

Portuguese tax residents must file their annual income tax return (Modelo 3 IRS) between April 1 and June 30 of the year following the tax year in which the gain was realized. Capital gains are reported in Anexo G (or Anexo G1 for exempt gains).

NIF: Your Portuguese Tax Number

Before you can file taxes or buy/sell property, you need a NIF (Número de Identificação Fiscal). This is your Portuguese tax identification number, and obtaining one should be among the first things you do when moving to Portugal.

Payment

Any tax due is typically payable by August 31 of the filing year, though the exact deadline may vary. If you owe a significant amount, be sure to set aside funds.

Common Mistakes Expats Make

  • Not reporting foreign capital gains: As a Portuguese tax resident, you must declare worldwide gains. Failure to do so can result in penalties.
  • Missing the reinvestment deadline: If you claim the primary residence exemption but fail to reinvest within 36 months, Portugal will claw back the tax with interest.
  • Ignoring DTAs: Many expats pay tax twice unnecessarily because they don't claim relief under a double taxation agreement.
  • Poor record-keeping: Keep all purchase contracts, receipts for improvements, and proof of foreign taxes paid. The burden of proof is on you.
  • Confusing tax residency timing: Selling an asset in January after arriving in Portugal in the previous September may already trigger Portuguese worldwide taxation.

Frequently Asked Questions

Do I pay capital gains tax in Portugal on property I sell in my home country?

If you are a Portuguese tax resident, yes — Portugal taxes your worldwide income, including foreign property gains. However, a DTA may provide relief through an exemption or foreign tax credit. If you reinvest in a new primary residence, the reinvestment exemption may apply.

Is there a capital gains tax exemption for long-held property?

Portugal does not offer a blanket exemption based on how long you've held real estate. However, the inflation adjustment coefficients applied to the purchase price increase with the holding period, which reduces the taxable gain. For crypto assets, holding for more than one year provides a full exemption.

How are capital gains taxed under the new IFICI regime?

The IFICI regime primarily benefits qualifying employment and self-employment income. Foreign capital gains may be exempt in certain circumstances, but the specifics depend on the DTA and the type of asset. Not all expats will qualify for IFICI, and the rules are more targeted than the former NHR.

Can I offset capital losses against capital gains?

Yes. Capital losses on securities can be offset against capital gains on the same category of income within the same tax year and the following five years. For real estate, the rules are more limited — you generally cannot offset a loss on property against other types of income.

What happens if I become a non-resident after selling an asset in Portugal?

If you were a tax resident at the time of the sale, Portugal taxes the gain under resident rules. If you sell Portuguese real estate after becoming a non-resident, the 28% flat rate (or the resident election for EU/EEA citizens) applies.

Conclusion: Key Takeaways for Expats Moving to Portugal

Moving to Portugal is an exciting step, but getting your capital gains tax planning right from the start can save you thousands of euros. Here are the essential points to remember:

  • Tax residency is everything: Once you're a Portuguese tax resident, your worldwide capital gains are potentially taxable. Plan asset disposals carefully around your move.
  • Rates vary by asset and residency: Real estate gains for residents benefit from the 50% inclusion rule; securities and crypto are taxed at 28% (with a holding-period exemption for crypto).
  • The classic NHR is closed to new applicants — check if you qualify for the new IFICI regime.
  • Double taxation agreements are your best friend. Always check the relevant DTA and claim relief.
  • The primary residence reinvestment exemption is one of the most powerful tax-saving tools available.
  • Keep impeccable records of all acquisition costs, improvements, and foreign taxes paid.
  • File on time (April 1 – June 30) and report all worldwide gains.
