For Portuguese tax residents under the Non-Habitual Resident (NHR) regime, the taxation of foreign capital gains remains one of the most sensitive and frequently misunderstood topics — particularly when it involves real estate located outside Portugal.
A recurring question we see from internationally mobile taxpayers is:
If I sell a property located abroad while benefiting from the NHR regime, are the capital gains exempt from Portuguese tax?
The answer is nuanced and depends on international tax treaties, domestic exemption rules, and the method chosen to eliminate double taxation.
Worldwide Taxation Still Applies to NHRs
Even under the NHR regime, Portuguese tax residents are subject to worldwide taxation.
This means that:
• Capital gains derived from the sale of foreign real estate
• Are, in principle, reportable in Portugal
• Even when the property is located entirely outside Portuguese territory
The NHR regime does not remove reporting obligations — it may, however, change how those gains are taxed.
Capital Gains on Real Estate: The General Rule
Gains arising from the sale of real estate are classified as Category G income.
They are calculated as:
• Sale value
• Minus acquisition value
• Adjusted for legally admissible costs
Special exclusions may apply for a main permanent residence, but only under strict conditions and typically limited to Portuguese or EU/EEA property. These exclusions are generally not applicable to third-country property.
How the NHR Regime Treats Foreign Capital Gains
Although the NHR regime was formally repealed for new entrants, it remains fully applicable to taxpayers who validly registered before the repeal and are still within their 10-year entitlement period.
For those taxpayers, foreign-source capital gains may qualify for exemption in Portugal, provided specific conditions are met.
When Does the Exemption Apply?
Foreign capital gains may be exempt from Portuguese taxation under the NHR regime if one of the following conditions is satisfied:
• The gains may be taxed in the source country under an applicable Double Tax Treaty
• Or, in the absence of a treaty, the gains follow the OECD Model Convention rules
• The source country is not classified as a preferential tax jurisdiction
• The income is not deemed Portuguese-sourced under domestic rules
When these conditions are met, Portugal applies the exemption method rather than taxing the gains directly.
Real Estate Located Abroad and Treaty Allocation
Most tax treaties allocate taxing rights over real estate capital gains to the country where the property is located.
This means:
• The source country is allowed to tax the gain
• Portugal recognises that taxing right
• Portugal may exempt the gain under the NHR framework
The key point is not whether tax is actually paid abroad, but whether the foreign state has the legal right to tax.
Does Exemption Mean “No Impact” in Portugal?
No.
Even when exempt, foreign capital gains must still be:
• Reported in the Portuguese tax return
• Included for rate-setting purposes
This mechanism, known as progressivity, means the exempt gain can increase the marginal IRS rate applied to other taxable income.
Optional Alternative: Tax Credit Method
NHR taxpayers are not forced to use the exemption method.
They may choose instead to:
• Include the foreign capital gain in taxable income
• Claim a foreign tax credit for tax paid abroad
This option may be advantageous when:
• The foreign tax burden is low
• Losses are involved
• Strategic income alignment is required
However, once chosen, this approach has material tax consequences and must be carefully modelled.
Practical Implications for International Property Owners
This analysis is particularly relevant for:
• NHRs holding property in non-EU countries
• Long-term expatriates with inherited real estate abroad
• Individuals planning asset disposals during their NHR period
• Taxpayers exposed to geopolitical or treaty-related risks
Incorrect structuring or reporting may lead to double taxation, penalties, or loss of NHR protection.
Key Takeaways
• NHRs are still taxed on worldwide income
• Foreign real estate capital gains may be exempt
• Treaty taxing rights are decisive
• Exempt gains still affect IRS rates
• A tax credit alternative may be elected
Each transaction must be assessed before the sale, not after.
