The Portuguese real estate market continues to evolve, and in 2026, significant changes were made to the capital gains tax regime. The main goal of these changes is to encourage investment in rental housing and increase the supply available on the market.
If you’re thinking about selling a property, now is the ideal time to understand the new rules and see how they might affect your tax situation.
What are capital gains?
Capital gains are the profit realized from the sale of a property. In simple terms, they result from the difference between the sale price and the purchase price, after taking into account factors such as inflation adjustments, renovation costs, deed fees, registration fees, real estate brokerage commissions, and other legally deductible expenses.
It is this gain that may be subject to personal income tax (IRS).
What changed in 2026?
One of the main changes is the possibility of benefiting from a capital gains tax exemptioncapital gains when the proceeds from the sale are reinvested in the purchase of properties intended for rental housing at moderate rents, provided that the conditions set forth in the new legislation are met.
This measure represents a significant change, as the benefit is no longer exclusively tied to reinvestment in a new primary residence but now also encourages an increase in the supply of rental housing.
What are the conditions?
To benefit from this program, you must meet several legal requirements, including:
- Reinvest the proceeds from the sale within the timeframes established by law.
- Purchase a property intended for residential rental.
- Comply with the limits set for moderate rents.
- Keep the property available for rent for the legally required period.
Each situation must be analyzed on a case-by-case basis, and it is advisable to seek expert advice before proceeding with the sale.
Who can benefit?
The new rules may be of particular interest to:
- Owners who intend to sell a property that has appreciated significantly in value.
- Real estate investors.
- Families looking to reorganize their assets.
- Owners looking to invest in the rental market.
A preliminary analysis could result in significant tax savings.
Does the Permanent Primary Residence regime still exist?
Yes.
The traditional regime remains in place, allowing for the exclusion of capital gains tax when the proceeds from the sale of a permanent primary residence are reinvested in a new permanent primary residence, provided that all conditions set forth in the IRS Code are met.
Thus, there are currently different tax exemption mechanisms in place, applicable depending on how the proceeds from the sale are used.
Why is it important to plan before selling?
Many homeowners only analyze the tax impact after the deed is signed.
However, proper planning can allow you to:
- Significantly reduce the tax owed.
- Take advantage of existing tax benefits.
- Avoid errors on your income tax return.
- Determine the best reinvestment strategy.
A decision made before the sale can make a difference of several thousand euros.

Conclusion
Recent changes to the capital gains tax regime represent an opportunity for many property owners who wish to sell a property and strategically reinvest the capital.
Each case has its own unique characteristics and must be analyzed individually, taking into account the type of property, the purpose of the reinvestment, and the owner’s tax situation.
Before making any decision, seek professional advice to ensure you take full advantage of all the benefits provided by the law.
