Long-Term Rentals in Portugal: Tax Benefits and What Changed in 2026

Portugal has introduced new tax incentives for residential rentals, including a reduced 10% tax rate, exemptions for qualifying rental income and benefits for certain property investments.

If you own property in Portugal, are considering investing in residential real estate or want to understand how the long-term rental market works, the tax rules can make a significant difference.

In 2026, Portugal introduced new measures to encourage residential rentals, particularly properties offered at moderate and affordable rents.

These changes build on the existing tax incentives for longer rental agreements and introduce additional benefits depending on the rental price, type of property and investment structure.

For international property owners and non-resident investors, understanding these rules is particularly important when calculating the costs and potential returns of a rental property.

But which tax benefits are available, and how do they work?

How Is Long-Term Rental Income Taxed in Portugal?

Rental income from property located in Portugal is generally subject to Portuguese taxation, even when the property owner lives abroad.

For individuals receiving residential rental income under Category F of the Portuguese Personal Income Tax Code, known as IRS, the standard autonomous tax rate is generally 25%.

However, this rate may be reduced depending on the duration of the lease and whether the rental agreement qualifies for specific tax incentives.

The applicable treatment depends on several factors, including the purpose of the rental, the monthly rent, the duration of the contract and whether the property is owned personally or through a company.

Portuguese tax residents may also have the option to aggregate rental income with other taxable income, subject to the applicable tax rules.

Commercial rental income follows a different framework, with a standard autonomous rate of 28% for individuals.

What Are the Tax Benefits for Long-Term Rental Contracts?

Portugal has traditionally encouraged longer residential leases through reduced income tax rates.

For qualifying contracts intended as the tenant's permanent residence, the applicable autonomous IRS rate generally decreases as the contract duration increases.

These reduced rates are subject to specific legal conditions, including restrictions concerning the rental amount and contractual requirements.

Additional reductions may also apply to certain qualifying renewals of contracts lasting at least five years.

However, if a contract ends before the required minimum duration, previously applied tax benefits may need to be reassessed.

Longer leases can also provide greater predictability in rental income and potentially reduce the costs associated with frequent tenant changes.

But the introduction of new tax incentives in 2026 means that contract duration is no longer the only factor to consider.

New for 2026: A 10% Tax Rate on Qualifying Residential Rental Income

One of the most significant changes introduced by Decree-Law No. 97/2026 is a reduced 10% autonomous IRS rate for qualifying residential rental income.

The measure applies to rental income from contracts intended exclusively for residential use, provided the monthly rent does not exceed the legally defined moderate rent threshold.

For 2026, this threshold is generally €2,300 per month, equivalent to 2.5 times the national monthly minimum wage.

The reduced tax rate applies to qualifying rental income received until 31 December 2029, unless another more favourable rate applies.

The measure produces effects from 1 January 2026 and applies to both new and existing contracts. It does not require any application or prior approval.

What Does the New Rate Mean in Practice?

Consider a property generating €1,500 in monthly rental income.

Over a year, that represents €18,000 in gross rental income.

Assuming the taxable rental income is also €18,000, the difference between the standard rate and the reduced rate would be:

Potential annual tax difference: €2,700.

This is a simplified example. Actual taxation depends on eligible deductions, the applicable tax regime and the circumstances of the property owner.

For property investments, the reduced rate may change the financial comparison between different residential rental arrangements.

Can Long-Term Rental Income Be Tax-Free in Portugal?

Potentially, yes.

Portugal introduced the Simplified Affordable Rental Regime (Regime Simplificado de Arrendamento Acessível, or RSAA), which took effect on 1 September 2026.

Under this regime, qualifying rental income may be exempt from Portuguese Personal Income Tax (IRS) or Corporate Income Tax (IRC).

This exemption is separate from the 10% reduced tax rate.

The RSAA is intended for qualifying residential rental agreements that meet specific requirements concerning rental prices, contract duration and registration.

What Are the Rent Limits?

Unlike the general €2,300 moderate rent threshold, the RSAA does not apply a single maximum rent across Portugal.

The applicable limits depend on the location and characteristics of the property, using a framework based on 80% of local median rental values.

The detailed limits by property type are regulated under Ministerial Order No. 454/2026/1, published on 13 October 2026.

This means that a property in Lisbon may have a different applicable rental ceiling from a similar property in Porto or another municipality.

What Are the Minimum Contract Durations?

For a property rented as the tenant's permanent residence, the minimum duration is generally three years.

Qualifying temporary residential rental agreements may have a minimum duration of three months.

Additional conditions apply, namely registering the contract on the platform of the Portuguese Housing and Urban Rehabilitation Institute (IHRU), through which it is also communicated to the Portuguese Tax Authority.

Under Portugal's new rental income tax exemption, qualifying residential properties may therefore generate income that is exempt from IRS or IRC, provided all applicable conditions are satisfied.

Buying Property in Portugal to Rent Out: What Taxes Apply?

For anyone considering a residential rental investment, income tax is only part of the calculation.

Taxes associated with purchasing and owning the property can also influence the investment's overall financial outcome.

Property Transfer Tax (IMT)

IMT is generally payable when purchasing real estate in Portugal.

The applicable rate depends on factors including the property's value, intended use and the buyer's tax circumstances.

As part of Portugal's 2026 real estate tax changes, a flat 7.5% IMT rate was introduced for certain non-resident buyers acquiring residential property.

The rate applies to acquisitions made from 25 May 2026. It does not apply where the buyer is, or has previously been, a Portuguese tax resident, and the difference may be recovered if the buyer becomes a Portuguese tax resident within two years or rents out the property under the conditions described below.

Municipal Property Tax (IMI)

IMI is an annual tax generally payable by property owners.

For urban properties, rates normally range from 0.3% to 0.45% of the property's taxable value, known as Valor Patrimonial Tributário (VPT).

The rate is determined by the relevant municipality.

IMI is calculated on the taxable property value, which may differ significantly from the property's purchase price or market value.

Additional Municipal Property Tax (AIMI)

AIMI is an additional property tax that may apply to certain residential properties and building land.

For individual owners, a general €600,000 deduction may apply to the aggregate relevant taxable property value, subject to statutory conditions.

Different rates and rules apply depending on whether the property is held by an individual, jointly or through a company.

Can Non-Resident Investors Benefit From IMT Adjustments?

One of the changes introduced in 2026 concerns certain non-residents purchasing residential property for qualifying rental purposes.

Under the legislation, buyers who initially pay the 7.5% IMT rate may be able to request a tax adjustment if specific conditions are met.

These include:

• The property must be rented within six months of acquisition.
• Monthly rent must remain within the applicable moderate rent threshold.
• The property must be rented for at least 36 months, consecutive or otherwise, during the first five years following acquisition.
• The relevant request must be submitted within the statutory deadline.

Where the conditions are satisfied, an adjustment may be available for the difference between the IMT initially paid and the amount calculated under the standard rates.

This can be particularly relevant for international buyers planning to acquire residential property while maintaining tax residency abroad.

However, the adjustment is not automatic, and eligibility should be assessed before making assumptions about acquisition costs.

What About International Property Owners and Non-Residents?

Owning property in Portugal does not automatically make someone a Portuguese tax resident.

However, rental income generated by property located in Portugal is generally subject to Portuguese taxation, regardless of where the owner lives.

For example, a person living in the United Kingdom or United States who owns a rented apartment in Lisbon may have Portuguese income tax obligations.

Depending on their country of tax residence, they may also be required to declare the rental income abroad.

Applicable double taxation agreements and domestic tax rules may affect the final treatment.

The distinction between Portuguese tax residency and non-resident taxation is therefore important when evaluating an international property investment.

Foreign nationality alone does not determine the applicable tax rate.

The relevant tax treatment depends on the owner's tax residency, the nature of the income and the conditions of the applicable regime.

What Expenses Can Be Deducted From Rental Income?

Portuguese rental income tax is generally calculated on net taxable income rather than simply the total rent received.

For individuals receiving Category F rental income, certain expenses directly associated with obtaining or maintaining that income may be deductible.

Depending on the circumstances, these may include:

• Qualifying maintenance and repair costs
• Condominium expenses borne by the property owner
• Municipal Property Tax (IMI)
• Certain insurance costs
• Other eligible expenses directly associated with the rental property

However, not every expense qualifies.

Mortgage interest, depreciation and certain costs relating to furniture, appliances and decorative items are generally excluded from Category F deductions.

Keeping accurate records and supporting invoices is therefore important.

Does Owning Rental Property Through a Company Change the Tax Treatment?

Yes.

The taxation of rental income can differ depending on whether a property is owned by an individual or through a company.

The 2026 legislation introduced a separate incentive for qualifying residential rental income earned by corporate taxpayers and certain individual taxpayers operating under Category B with organised accounting.

Where the relevant conditions are met, only 50% of qualifying rental income may be considered for taxation.

This incentive applies to qualifying income received until 31 December 2029.

It is separate from the 10% autonomous IRS rate and from the exemption available under the RSAA.

However, holding a rental property through a company does not automatically produce a lower overall tax burden.

Corporate taxation, acquisition costs, financing, profit distributions and future capital gains may all influence the final result.

For international investors, ownership structure should therefore be assessed alongside the intended use of the property and the applicable tax obligations.

How Do Tax Benefits Affect Rental Property Returns?

A lower tax rate does not necessarily mean a better investment.

For example, a property owner may be able to charge a higher monthly rent on the open market but face a higher effective tax burden.

Alternatively, a lower monthly rent may qualify for a reduced tax rate or a full exemption.

The financial comparison should consider more than the headline rental price.

Important factors include:

1. Annual rental income
2. Applicable tax rates and exemptions
3. Maintenance and operating expenses
4. IMI and any applicable AIMI
5. Financing and property management costs
6. Vacancy periods
7. Contract duration and restrictions attached to the tax benefit

The relevant question is not simply how much rent a property can generate, but how much remains after tax and other costs.

This is particularly important for international investors comparing different properties, locations and rental arrangements.

Do Rental Contracts Need to Be Registered in Portugal?

Yes.

Residential rental agreements generally need to be communicated to the Portuguese Tax Authority through Portal das Finanças.

Depending on the circumstances, property owners may also be required to issue rental receipts and declare rental income in their annual tax returns.

Additional reporting requirements apply under certain tax incentive regimes, including the RSAA.

Registration alone does not automatically establish eligibility for a reduced tax rate or exemption.

The rental agreement must also satisfy the relevant legal requirements concerning its duration, rent and intended use.

Portugal's 2026 tax changes introduced new considerations

Portugal's 2026 tax changes introduced new considerations for anyone involved in the residential rental market.

Alongside the traditional tax reductions for longer leases, qualifying rental income may now benefit from a 10% rate or, under the Simplified Affordable Rental Regime, a full income tax exemption.

Certain residential property investments may also qualify for acquisition tax adjustments and other incentives.

For international property owners and investors, these measures can influence decisions about purchasing, holding and renting residential property in Portugal.

However, each incentive has its own conditions, and the financial outcome depends on more than the tax rate applied to rental income.

Understanding the applicable rules before purchasing a property or entering into a rental agreement can help identify available benefits and avoid unexpected costs.
