For an individual landlord, Portugal rental income tax for foreigners is not one fixed “non-resident rate”. In 2026, qualifying residential rental income can be taxed at 10% where the monthly rent stays within the new moderate-rent ceiling—currently €2,300—and the statutory conditions are met. Other residential rental income is generally taxed at 25%, qualifying long-duration permanent-home leases can fall to 15%, 10% or 5%, and qualifying contracts under the new simplified affordable-rental regime (RSAA) can be exempt from IRS. Non-residential Category F property income is generally taxed at 28%.
The decisive variables are therefore not nationality alone. They are Portuguese tax residence, the use of the property, the rent level, the contract term and whether a specific incentive regime applies. The 10% rule is especially important because it took effect from 1 January 2026 and also reaches qualifying residential leases already in progress.
Qualifying residential rent within the moderate-rent limit, for income through 31 December 2029.
General autonomous rate for residential Category F income when no more favourable rule applies.
General autonomous rate for property income not covered by the residential-rental rule, including ordinary non-residential Category F income.
Possible IRS exemption for a contract that actually qualifies under RSAA, effective from 1 September 2026.
Important: these are statutory rate frameworks, not a personalised tax result. A lower long-duration residential rate may override the 10% rule where it is more favourable.
The 2026 Rule That Changes the Answer
Many older guides still begin and end with “25% tax on residential rent”. That is no longer a complete statement for 2026. Article 45-C of Portugal’s Tax Benefits Statute, added by Decree-Law 97/2026, sets a 10% autonomous IRS rate for Category F income from leases used exclusively for residential letting when the monthly rent does not exceed the statutory moderate-rent ceiling. The measure applies to qualifying income earned through 31 December 2029 and takes effect from 1 January 2026.
The ceiling is defined as 2.5 times the monthly minimum wage fixed for 2026. The official 2026 minimum wage is €920, so the present statutory ceiling is €2,300 per month. Decree-Law 97/2026 allows that ceiling to be updated by ministerial order, so a landlord signing or changing a lease later should re-check the current limit rather than treating €2,300 as permanent.
The law also prevents artificial splitting of the price. For the threshold, the relevant rental value can include amounts linked to permanently attached furniture, equipment, accessories and services that add value, even where they are put into separate legal arrangements. With several tenants, the test is against the total rent, not each tenant’s share.
This is a material information-gain point for anyone researching Portugal rental income tax for foreigners: the 10% rule is a national residential-rental tax incentive, not a special concession only for Portuguese citizens or only for non-residents.
Foreign Nationality Is Not the Tax Test
“Foreigner” is useful search language, but it is not the tax category that decides the result. Under the IRS Code, a Portuguese tax resident is generally taxed on worldwide income; a non-resident is generally taxed only on Portuguese-source income. Tax residence is tested under Article 16 of the IRS Code, including the more-than-183-days test and the alternative habitual-home test. A foreign citizen can be Portuguese tax resident, while a Portuguese citizen can be non-resident.
For a landlord living abroad, Portuguese rent remains Portuguese-source income. That is why a non-resident owner can still have Portuguese IRS obligations even when the tenant, bank account or property manager is in Portugal. Conversely, becoming Portuguese tax resident does not make the rental income disappear; it changes the broader filing context and may affect options such as aggregation.
Category F is property income, not every form of accommodation income
This dossier addresses an individual who earns ordinary Portuguese rental income taxed as Category F. Alojamento Local, a rental activity treated as business income, or property held through a company can fall under different Category B or corporate-tax rules. Do not apply the rates in this article automatically to those structures.
How Portugal Rental Income Tax for Foreigners Works in Practice
10% · moderate residential rent
Article 45-C applies where the contract is exclusively for residential letting and the monthly value stays within the Decree-Law 97/2026 limit. For 2026 that means €2,300, subject to any later lawful update. The provision runs through income earned by 31 December 2029.
25% · other residential rent
Article 72 sets the autonomous rate for residential Category F income at 25%. This remains the starting point where Article 45-C or another more favourable regime does not apply.
15%, 10% or 5%
For qualifying permanent-housing contracts, Article 72 reduces the 25% rate by 10 percentage points for terms of at least five but under ten years, 15 points for at least ten but under twenty, and 20 points for at least twenty years. Additional renewal reductions can apply to the five-to-ten-year band, subject to statutory limits and conditions.
28% · general property-income rate
Property income not covered by the residential paragraph of Article 72 is generally subject to the 28% autonomous rate. A shop, office or other ordinary non-residential letting therefore should not be assumed to receive the residential 10% or 25% treatment.
The long-duration reductions are not unconditional. Among other restrictions, Article 72 limits their availability for certain new contracts signed from 2024 when rent is substantially above the statutory reference limits, and an early termination attributable to the landlord can trigger recovery of the tax benefit with compensatory interest. Contract duration alone is not enough; the complete eligibility test matters.
10% Moderate-Rent Rule vs RSAA: Do Not Confuse Them
Two 2026 reforms can sound similar because both reward lower residential rents, but they are legally separate. This is where some online summaries become unreliable.
Moderate-rent 10% rule
- Effective for qualifying income from 1 January 2026.
- Current 2026 national ceiling: €2,300 per month.
- Applies to leases used exclusively for residential letting, including qualifying contracts already in progress.
- The enacted Article 45-C does not itself state a general three-year minimum lease term.
- Ends for income after 31 December 2029 unless legislation changes.
Affordable-rental IRS exemption
- Effective from 1 September 2026.
- Qualifying rental income is exempt from IRS.
- Permanent-residence contracts require a minimum three-year term; qualifying temporary-residence contracts require at least three months.
- Rent ceilings are a separate typology-and-municipality framework based on 80% of INE median rents.
- Landlords have specific IHRU-platform and Tax Authority communication duties.
Do not import the RSAA three-year term into Article 45-C. Some current secondary summaries appear to merge the two regimes. The primary text of Article 45-C sets the residential-use and rent-limit tests but does not state a general three-year minimum. The three-year rule appears in the separate RSAA rules for permanent residence.
RSAA is potentially more generous because a fully qualifying contract can be exempt from IRS, but it is also more structured. Its maximum rent is not the same €2,300 national moderate-rent ceiling. The law requires RSAA ceilings by property type, based on 80% of the INE median rental value for the municipality, with implementing rules and automatic updates. Before relying on a 0% result, confirm the current property-specific ceiling and the IHRU process for that contract.
What You Can Deduct from Category F Rental Income
The tax rate is applied to taxable Category F income after the deductions permitted by Article 41, not automatically to every euro of gross rent. The core rule in Article 41 permits expenses actually borne and paid to obtain or guarantee the rental income, with explicit exclusions.
Commonly within the statutory deduction framework
- Eligible maintenance and conservation costs.
- Mandatory condominium charges actually paid by the owner.
- IMI and Stamp Duty for a property whose rental income is taxed in that fiscal year.
- Rent-guarantee insurance.
- Eligible conservation and maintenance costs paid in the 24 months before the rental begins, if the property was not used for another purpose in the meantime.
Expressly excluded or restricted
- Financial costs—which means mortgage interest is not an ordinary Category F deduction under Article 41.
- Depreciation.
- Furniture and household appliances.
- Comfort or decoration items.
- Additional to IMI (AIMI).
Documentary evidence is required. A cost being economically connected with the property does not automatically make it tax-deductible.
A Category F net loss can generally be carried forward against positive Category F results for six years. The carry-forward can cease if the relevant property does not generate Category F income for at least 36 months, consecutive or intermittent, within the following five years.
Worked Example: a Non-Resident Landlord in 2026
Assume a non-resident individual lets a Portuguese apartment exclusively for housing at €1,500 per month throughout 2026. Gross rent is €18,000. Assume €3,000 of properly documented costs are deductible under Article 41, producing €15,000 of taxable Category F income.
− €3,000 eligible deductions
= €15,000 taxable Category F income
× 10%
= €1,500 illustrative Portuguese IRS
Because €1,500 is below the current €2,300 moderate-rent ceiling, the 10% Article 45-C rate could apply if all statutory conditions are satisfied and no more favourable rate applies. Applying an outdated blanket 25% rate to the same €15,000 would produce €3,750—€2,250 more. That difference explains why a 2026 analysis must identify the lease regime before calculating tax.
Change one fact and the result can change. If the apartment rents for €2,600 per month, the current moderate-rent test is not met, so the general 25% residential rate becomes relevant unless a separate reduction applies. If instead a qualifying permanent-housing contract has a twenty-year term, the long-duration reduction can bring the autonomous rate to 5%, which is more favourable than 10%.
Withholding, Registration and Annual Filing
Tax collection mechanics are separate from the final rate. Under Article 101 of the IRS Code, a tenant or payer that has, or is required to have, organised accounting must generally withhold on gross Category F payments. The ordinary Category F withholding rate is 25%; for income covered by Article 45-C, the code now specifies 10%. Withholding does not change the need to establish the correct annual taxable income and filing position.
The landlord must also communicate an urban lease to the Tax Authority. The official process uses the Stamp Duty Modelo 2 and, as a general rule, the contract is communicated by the end of the month following the start of the lease. The communication generates Stamp Duty equal to 10% of one month’s rent, payable within the same deadline. Contract changes and termination also have communication deadlines. This Stamp Duty is a contract tax; it is not the annual IRS rate on rental profit.
For annual IRS, the Tax Authority’s current filing window for Modelo 3 is 1 April to 30 June of the following year, submitted electronically. Individual landlords normally report Category F rental income through Modelo 3 and Anexo F where filing is required. That means 2026 rental income is generally dealt with in the 2027 filing cycle.
Non-residents should also check their Portuguese fiscal-notification setup. For residents of the EU, Norway, Iceland or Liechtenstein, appointing a Portuguese fiscal representative or opting into the relevant notification channel is generally optional. For residents of other countries who have a Portuguese tax relationship—property ownership is an express example—the Tax Authority generally requires either a Portuguese fiscal representative or enrolment in an accepted electronic-notification channel, subject to the specific rules and exceptions.
Double Taxation and the Country Where You Live
Paying Portuguese tax does not necessarily finish the compliance analysis. A landlord who is tax resident in another country may also need to declare the Portuguese rent there. Portugal’s double-tax treaties generally allocate taxing rights and the residence country’s domestic rules determine how double-tax relief is implemented, often through a credit or exemption mechanism. The exact result is treaty-specific.
Use the Tax Authority’s current treaty register and then check the rules of the country where you are tax resident. Do not assume that a Portuguese 10%, 25% or 28% payment is the final worldwide burden, and do not assume that the full Portuguese amount will always be creditable abroad.
Need help organising the questions before you speak to a tax professional?
PortugalPath can help you map the property, residence status, lease type and documentation issues that need verification. Tax calculations and legal conclusions should be confirmed for your own facts with the appropriate qualified professional or authority.
What to Verify Before Acting
Confirm whether you are Portuguese resident, partially resident or non-resident for the relevant tax year.
Confirm the income is genuinely Category F rather than Alojamento Local, Category B activity or company income.
Check that the lease is exclusively residential if relying on the 10% Article 45-C rule.
Re-check the moderate-rent ceiling at the relevant date and include linked charges that the law treats as part of rental value.
If claiming a long-duration reduction or RSAA treatment, verify the exact duration and all disqualifying conditions.
Keep invoices and proof of payment; do not deduct mortgage interest merely because it financed the property.
Confirm the lease, Stamp Duty, rent-receipt and annual reporting obligations have been completed.
Check the applicable double-tax treaty and the foreign tax-credit or exemption mechanics where you live.
The practical position on Portugal rental income tax for foreigners in 2026 is therefore more favourable—and more conditional—than a single headline rate suggests. The first question is no longer “Are you foreign?” but “What kind of rental income is this, what does the contract say, and which current statutory regime does it satisfy?”
