Life changes. Careers evolve. Families grow. People move.

Portugal’s tax system has slowly begun to reflect that reality, especially regarding capital gains in Portugal.

Recent updates to the Personal Income Tax Code (IRS), introduced following Decree-Law No. 57/2024, brought meaningful adjustments to two areas that matter greatly to property owners:
• The reinvestment of real estate capital gains in Portugal
• Deductions related to rental income

The objective is clear: encourage mobility while maintaining tax fairness. Below, we break down what this means in practical terms.

Reinvestment of Real Estate Capital Gains in Portugal

When selling a primary residence in Portugal, capital gains may be exempt from IRS, provided specific reinvestment conditions are met.

The Core Rule

To benefit from the exemption:

• The property sold must have been the taxpayer’s (or household’s) primary residence.
  
• It must have served as such for at least 12 months prior to the sale, evidenced by fiscal domicile registration.
  

If the new property is purchased before the sale, the 12-month period is counted from the date of reinvestment.

This clarification provides welcome flexibility for individuals or families who need to secure their next home before completing a sale.

When Exceptions Apply

The law now better acknowledges real-life changes.

The 12-month rule may be relaxed in situations such as:

• Marriage or beginning a de facto union
  
• Divorce or dissolution of partnership
  
• Increase in number of dependents
  
• Professional relocation or geographic mobility
  

In addition, a previous restriction has been removed: taxpayers are no longer excluded from the regime simply because they benefited from the exemption within the same year or in the previous three years.

This change alone significantly increases planning flexibility for homeowners navigating transitional periods.

Deductions on Rental Income

Another relevant adjustment concerns taxpayers who relocate and choose to rent out their former primary residence.

Under the current regime, it is possible to deduct certain housing expenses from gross rental income, provided strict conditions are met.

Requirements

• The property now generating rental income must have previously served as the taxpayer’s primary residence for at least 12 months.
  
• The taxpayer must relocate their new primary residence to a location more than 100 km away.
  
• Both lease contracts must be properly registered on the Portuguese Tax Authority Portal.
  

In practical terms, this supports individuals who relocate for professional reasons but retain ownership of their former home.

What This Means in Practice

These measures reflect a gradual shift toward a more adaptable tax framework. Mobility, whether driven by career, family, or lifestyle, is no longer treated as an anomaly but as part of modern life.

That said, these regimes remain technical. Timing, documentation, and fiscal residency status are critical. Small missteps can affect eligibility.

For property owners considering selling, reinvesting, or converting a former home into a rental, tax planning should happen before any transaction is signed, not after.
