Portugal Property Tax Guide 2026 — IMI 0.3-0.45% & IMT 0-8%

IMI — Imposto Municipal sobre Imóveis (Annual Property Tax)

Rates:

• Urban properties: 0.3% to 0.45% of the VPT, as set by the municipality. Most municipalities apply 0.3–0.4% for urban residential properties. The rate can be reduced to 0.2% for properties subject to rent control or increased up to 0.5% for vacant or degraded urban buildings.
• Rural properties: 0.8% of the VPT.

Payment: IMI is payable annually, typically in one instalment if under €100, or in two instalments (May and November) if between €100 and €500, or three instalments (May, August, November) if over €500. The assessment notice is issued in April/May each year. Families with dependants may receive an IMI reduction: 5% per child (up to a maximum of 15% for three or more children) on the primary residence, provided the property's VPT does not exceed approximately €200,000.

IMI on rental properties: Owners of rental properties pay IMI at the standard rate. The IMI paid is a deductible expense against rental income for IRS purposes. Landlords who maintain rent-controlled tenancies may benefit from reduced IMI rates as low as 0.2%.

IMT — Imposto Municipal sobre Transmissões (Property Transfer Tax)

IMT is a progressive tax paid by the buyer on property acquisitions. It applies to both the purchase price and the VPT, whichever is higher. The rate structure for urban residential properties in 2026:

• Up to €105,759 — 0% (exempt)
• €105,760 to €155,439 — 2% (with a deduction of €2,115.18 from the calculated tax)
• €155,440 to €364,819 — 5% (with a deduction of €6,776.84)
• €364,820 to €596,769 — 7% (with a deduction of €14,345.75)
• €596,770 to €1,096,170 — 8% (with a deduction of €20,191.32)
• Over €1,096,170 — 8% (no deduction applies to the excess)

Urban non-residential properties (commercial, industrial): progressive rates from 0% to 7.5%. Rural properties: IMT at 5% with no progressive structure. Owner-occupied primary residence: Buyers may qualify for a reduced IMT rate structure (the above brackets). The reduced rates require that the buyer does not own another property in Portugal and intends to use the purchased property as their permanent home.

IMT Exemptions

• Young people (under 35): Exemption from IMT and stamp duty on the first €316,773 of the purchase price for an owner-occupied primary residence, subject to income limits and property value caps (properties up to €316,773 are fully exempt; partial exemption applies up to €633,546).
• Rehabilitation properties: Reduced IMT (0%) on properties classified as urban rehabilitation areas (ARU) if purchased for renovation and the works are completed within 3 years.
• Relocation to Portugal: Residents returning to Portugal or new residents transferring their tax domicile may qualify for IMT exemptions on their primary residence under specific conditions.
• Mortgage enforcement sales: IMT may be reduced on properties acquired from banks in execution proceedings.

Stamp Duty on Property Transactions

In addition to IMT, property purchases attract stamp duty (Imposto do Selo) at 0.8% of the purchase price. This is paid by the buyer. Mortgages also attract stamp duty: 0.6% on the loan amount (for mortgages exceeding €5,000). Rental agreements are subject to stamp duty at 0.2% of the annual rent (if the lessor is a business), or 10% of the rent if paid by a tenant as a withholding obligation for non-resident landlords without a Portuguese representative.

FAQs

How is the VPT determined?

The VPT (Valor Patrimonial Tributário) is determined by the Portuguese Tax Authority using a formula based on the property's construction cost, location coefficient (including proximity to amenities, transport, and services), comfort coefficient (parking, pools, central heating, etc.), and age coefficient. The VPT is recalculated upon property transfer or significant renovation. Urban properties are revalued approximately once every 3 years.

Can I challenge my IMI assessment?

Yes. If you believe the VPT is incorrectly calculated, you can submit a challenge (reclamação) to the Tax Authority within 30 days of receiving the assessment notice. You may also request a new VPT assessment if the property's characteristics have changed. Legal recourse to the tax court is available if the administrative challenge is rejected.

Are non-residents subject to the same IMI rates?

Yes. Non-resident property owners pay IMI at the same rates as residents. There is no surcharge for non-residents on IMI. However, non-residents who hold property through offshore companies may face the higher AIMI rates discussed in the wealth tax guide.

What happens if I sell my property before the IMI payment is due?

IMI is assessed on the owner as of 31 December of the prior year. If you sell mid-year, the buyer reimburses you for the portion of IMI from the date of transfer to year-end, prorated daily, unless the deed of sale specifies otherwise. Contractual terms can vary.
