Portugal spreads its property taxes across the whole ownership cycle. You pay IMT and stamp duty when you buy, IMI every year you own, and AIMI only if your Portuguese holdings pass €600,000 in taxable value. Capital gains tax waits at the exit, and rental income has its own rules if you let the place out.
None of this should scare you off. Portuguese property taxes are moderate by western European standards, and the annual bills are calculated on a tax value that usually sits well below what you paid. But the mechanics matter, especially the gap between how a permanent home and a holiday home are treated. This HomeNSearch guide walks through every stage, with a worked example of a €300,000 second home in the Algarve. Everything below reflects the rules at the time of writing; the IMT brackets shift a little each January.
Before any tax: the NIF
You can't pay Portuguese tax without a Portuguese tax number. The NIF (Número de Identificação Fiscal) comes first in every purchase: banks won't open an account without it and the notary can't complete the deed. EU and EEA citizens can request one directly from any tax office. Buyers from elsewhere appoint a fiscal representative in Portugal, usually the lawyer handling the purchase, to receive tax correspondence on their behalf. Once you own the property, register for the Portal das Finanças as well. IMI bills, IMT assessments and AIMI notices all appear there, and paper letters posted to a foreign address have a way of arriving after the payment deadline has passed.
Buying: IMT, the transfer tax you pay before the deed
IMT (Imposto Municipal sobre as Transmissões Onerosas de Imóveis) is the big one at purchase. It's charged on the higher of the price or the property's tax value, and the rate depends on what you're buying and how you'll use it.
- A home you'll live in permanently is taxed on a progressive scale: 0% on the first slice (a little over €100,000 at the time of writing), then marginal steps of 2%, 5%, 7% and 8%, flattening into single rates of 6% and 7.5% at the top of the market.
- A second home or buy-to-let runs on the same ladder minus the free band, so the first slice is taxed at 1% instead of 0%.
- Rustic land pays a flat 5%, and commercial or other urban buildings pay 6.5%.
- A buyer acting through an entity in a blacklisted tax haven pays 10%, which is where the alarming "up to 10%" headline comes from. It doesn't apply to a normal individual buyer.
Timing trips people up. IMT isn't settled at the closing table. It has to be paid before the deed is signed, and the notary will ask for the receipt and refuse to complete without it. In practice your lawyer generates the assessment online a few days ahead of completion and you pay at a bank, a tax office or through the Finanças portal.
The steps around the tax itself, from the promissory contract through to the deed, are covered in our guide on how to buy property in Portugal.
Aged 35 or under? Your first home may be tax-free
Since August 2024, buyers aged 35 or under purchasing their first permanent home in Portugal pay no IMT and no stamp duty on values up to roughly €320,000. Between there and about €640,000 the relief is partial, with tax charged only on the slice above the exemption ceiling. Conditions apply. It has to be your first home, you must actually live in it, and you can't have owned residential property in the three years before the purchase. The measure is recent enough that many older guides still miss it, and it isn't restricted to Portuguese citizens: a 30-year-old foreign buyer who meets the criteria and moves in qualifies too.
Stamp duty: the flat 0.8%
Stamp duty (Imposto do Selo) is the simplest charge in the system. It's 0.8% of the same taxable base as IMT, paid at the deed. On a €250,000 purchase, €2,000. If you finance with a Portuguese mortgage, the loan attracts its own stamp duty of 0.6% for terms over five years, a cost worth remembering when you weigh cash against credit.
The worked example: a €300,000 second home in the Algarve
Say you're buying a two-bedroom apartment near Lagos for €300,000 as a holiday home. It won't be your permanent residence, so the second-home table applies from the first euro.
- IMT comes to a little under €12,000 once the price runs through the progressive bands, an effective rate of just under 4%.
- Stamp duty adds 0.8% of the price, or €2,400.
- First-year IMI depends on the tax value rather than the price. If the apartment's VPT is assessed at €180,000 and the municipality charges 0.35%, the annual bill is €630.
Call it €14,300 of tax at purchase plus the first annual bill, before notary, registration and legal fees. Had the same apartment been your permanent home, the free first band would have shaved about €1,000 off the IMT. And a 34-year-old first-time buyer moving in permanently would have paid no IMT or stamp duty at all.
One quirk worth knowing: IMI is billed to whoever owns the property on 31 December, so your first demand arrives the following spring. Anything over €500 is split into three instalments in May, August and November.
Owning: IMI, the annual tax that's smaller than you'd fear
IMI (Imposto Municipal sobre Imóveis) is Portugal's answer to council tax. Each municipality sets its own rate within a national band of 0.3% to 0.45% for urban property. A handful of councils under financial recovery programmes may charge up to 0.5%, and rustic land pays 0.8%. Lisbon sits at the bottom of the band; most Algarve municipalities charge somewhere in the middle.
The base is the VPT (Valor Patrimonial Tributário), a tax value the authorities calculate from a formula built on floor area, location, age and quality coefficients. The VPT is refreshed when a property changes hands, yet it still lands well below the market price in most cases, often by 30% to 50%. A coastal apartment selling for €400,000 might carry a VPT of €220,000, which at 0.35% means €770 a year. Buyers used to French taxe foncière or American property tax bills tend to be pleasantly surprised.
Reliefs exist too. A permanent home with a modest VPT can qualify for a three-year IMI exemption after purchase, subject to household income limits, and low-income households in low-value homes pay nothing on an ongoing basis.
Budget alongside IMI, though they aren't taxes: condominium charges on apartments, typically €50 to €150 a month depending on the building, and the utility standing charges that keep running while the place sits empty.
AIMI: the add-on above €600,000
AIMI (Adicional ao IMI) is often called Portugal's wealth tax, though it touches only real estate. Each owner adds up the VPT of their Portuguese residential property and building land, deducts €600,000, and pays 0.7% on the excess. The slice above €1 million is taxed at 1%, and above €2 million at 1.5%. Married couples and civil partners can file jointly, which doubles the allowance to €1.2 million. Companies pay 0.4% with no allowance.
Because the threshold is measured in VPT rather than market value, a single mid-range home almost never triggers it. A villa bought for €700,000 will usually carry a tax value comfortably under the €600,000 line. AIMI is aimed at large portfolios and prime Lisbon and Cascais stock, and for most foreign buyers it stays a theoretical tax.
Renting out: what the taxman takes from your rent
Income from long-term residential lets is taxed at a flat rate, 25% of net rent for most landlords since the 2023 housing package trimmed the old 28%. Commit to a longer contract and the rate steps down further; the discounts deepen with the length of the lease, which is the government's way of nudging owners toward stable tenancies. IMI, condominium charges, insurance, maintenance and repairs are deductible against the rent. Mortgage interest isn't. Residents can instead fold rental income into their general progressive assessment when that works out cheaper, which it sometimes does at low income levels.
Short lets are a different regime altogether. Letting through Airbnb-style platforms requires an Alojamento Local registration, the income is treated as business income rather than rent, and under the simplified regime only a portion of gross revenue is taxable. The catch is licensing: municipalities can freeze new AL registrations in high-pressure zones, and parts of Lisbon and Porto have done exactly that. Check whether a licence is obtainable, or transfers with the property, before you underwrite a purchase with holiday-let projections.
Small print: a new lease contract carries a one-off stamp duty of 10% of one month's rent when it's registered with the tax office.
Selling: capital gains without the horror stories
Portuguese residents are taxed on half the gain — the other half never enters the calculation. Sell for €150,000 more than your all-in acquisition cost and €75,000 is added to your income for the year at progressive rates. The acquisition cost includes the IMT and stamp duty you paid at purchase plus documented improvement works from the previous twelve years, and an inflation adjustment kicks in once you've held for more than two years.
Your main home gets an escape hatch. Reinvest the proceeds into another primary residence in Portugal or elsewhere in the EU or EEA within the statutory window and the reinvested share of the gain goes untaxed. Retirees and owners over 65 have a parallel option of rolling the proceeds into a pension or insurance product instead.
Non-residents were long taxed on the full gain at a flat rate, a rule EU courts chewed up in case after case. The regime has since been aligned: non-residents are now assessed on half the gain as well, though Portugal looks at worldwide income when setting the rate. The practical advice is unchanged. Hire a Portuguese accountant for the tax year in which you sell. Filing errors here are expensive.
How Portugal compares with Spain and Italy
Purchase taxes are where Portugal quietly wins the mid-market. Spain charges transfer tax of roughly 6% to 10% on resale homes depending on the region, from the first euro: the €300,000 Algarve apartment above would carry €30,000 of ITP in the Valencian Community against Portugal's €12,000 or so. The full Spanish picture is in our guide to taxes when buying property in Spain. Italy looks cheap for residents, with a 2% registration tax on a first home, but non-resident second-home buyers pay 9%, softened by the fact that Italian transfer tax is charged on low cadastral values rather than the price.
Annual costs bring the three countries closer together. Spain's IBI and Italy's IMU sit in a similar range to IMI, though Italy exempts main residences and Spain adds a regional wealth tax for larger estates. Portugal's AIMI bites only above €600,000 of tax value, so a typical one-property foreign owner faces some of the gentlest running costs of the three.

Frequently asked questions
Do foreign buyers pay higher property taxes in Portugal?
No. IMT, stamp duty, IMI and AIMI apply at the same rates regardless of nationality or residence. The only punitive rate is the 10% IMT for purchases made through entities in blacklisted tax havens. What every foreign buyer does need is a NIF, the Portuguese tax number, before signing anything.
When exactly is IMT paid?
Before completion. The tax office issues a payment reference, you settle it a day or two ahead of the deed, and the notary checks the receipt before anyone signs. Miss the payment and the completion date slips.
What is the VPT and why is it lower than my purchase price?
The VPT is the tax value assigned to every property through a formula based on size, location, age and build quality. It's refreshed when a property is sold, but the formula is conservative, so the result often lands 30% to 50% below the market price. IMI and AIMI are both calculated on it, which is what keeps Portuguese annual bills low.
Does Portugal charge inheritance tax on property?
Not as such. Spouses, children and parents inherit Portuguese property free of tax. Other heirs pay stamp duty at 10% of the property's tax value, and gifts of property follow the same logic, with the standard 0.8% property stamp duty added on top.
