Capital Gains Tax in Portugal: What Property Owners and Investors Need to Know
Whether you're a resident selling your primary home or an international investor disposing of real estate, understanding how capital gains tax works in Portugal is essential. Like in many countries, the sale of property in Portugal can trigger a capital gains tax liability, but there are important nuances, rates, and exemptions that can significantly affect how much tax you ultimately pay.
At Portugal Investment Properties, we support buyers and sellers through every step of the real estate journey, including helping clients understand their tax obligations. This article outlines how capital gains tax in Portugal works, who it applies to, current Portugal capital gains tax rates, and the most common exemptions available.
What Is Capital Gains Tax?
Capital gains tax (CGT) is the tax applied on the profit made from the sale of an asset — in this case, real estate. The gain is calculated as the difference between the purchase price (adjusted for inflation and certain allowable expenses) and the selling price.
In Portugal, CGT applies to both residents and non-residents when they sell real estate, but the rules and rates can differ depending on your tax residency status and the nature of the property sold.
Portugal Capital Gains Tax Rates
The Portugal capital gains tax rates vary based on whether the seller is a Portuguese tax resident or not.
-
For Portuguese tax residents: Only 50% of the gain is subject to taxation. The taxable amount is then added to the seller’s other income and taxed according to the progressive income tax rates (which range from approximately 14.5% to 48%).
-
For non-residents: The full 100% of the gain is subject to a flat tax rate of 28%. However, as of recent changes aligned with EU requirements, EU/EEA residents may opt to be taxed under the same regime as residents if it proves more favorable.
This difference in treatment can significantly affect your net proceeds from a property sale, so it's essential to plan ahead and consult with a tax advisor to choose the most beneficial option.
Calculating the Capital Gain
The capital gain is not simply the difference between purchase and sale price. Several factors and allowable deductions can reduce your tax liability. These include:
-
Purchase costs (including notary, registration, and legal fees)
-
Improvement costs (such as renovations, provided invoices are kept)
-
Real estate agent commissions
-
Inflation adjustment (for properties owned for more than 2 years, a coefficient is applied to reflect inflation)
This adjusted calculation allows you to report a lower net gain, and therefore, reduce your tax liability.
Tax on Property Sale Portugal: When and How It’s Paid
For residents, the capital gain is declared on your annual income tax return (IRS). For non-residents, it must be reported and paid within 30 days of the sale through a separate tax return.
If you’re selling through a Portuguese lawyer or accountant, they will typically handle this filing on your behalf. If you are a non-resident, you must also appoint a fiscal representative in Portugal, who will ensure you comply with all tax requirements.
Failure to declare and pay tax on property sale Portugal can lead to fines and interest charges, so it's critical to meet your obligations on time.
Capital Gains Tax Exemptions Portugal
There are several scenarios in which sellers can benefit from capital gains tax exemptions Portugal offers. These exemptions can make a significant difference, especially for residents selling a primary residence.
Here are the most notable exemptions:
-
Reinvestment Exemption (Primary Residence): If you're a Portuguese tax resident and selling your primary home, you may be exempt from capital gains tax if the proceeds are reinvested in another primary residence within the EU/EEA within 36 months (before or after the sale). This applies to both the seller and their immediate family.
-
Over 65s or Retirees: Residents aged 65 or older, or those who are retired, may also qualify for an exemption if they reinvest the sale proceeds into a qualifying long-term savings or pension product, such as an insurance contract or retirement fund, within six months of the sale.
-
Inheritance and Donations: In some cases, capital gains tax may not apply when the property is inherited or gifted within the family, though other stamp duty taxes may still apply.
-
Older Property Ownership: If the property was purchased before January 1989 (when Portugal introduced CGT on real estate), the sale is fully exempt from capital gains tax.
These exemptions are subject to specific conditions, so it’s essential to review them carefully and work with a professional who understands your unique situation.
