Buying a House in Portugal as a Finnish Buyer: 7.5% IMT, 6 Months

A Finnish flat is a bundle of shares in a housing company. A Portuguese flat is a piece of real estate, and a buyer who stays tax resident in Finland pays 7.5% to acquire it.

Decreto-Lei n.º 97/2026 fixed one rate for non-resident buyers of Portuguese housing, 7.5%, with every exemption and reduction switched off. Residence decides that, not the passport. Three narrow exceptions exist, and where one applies the money only comes back if you ask for it within six months.

IMT is short for Imposto Municipal sobre as Transmissões Onerosas de Imóveis. It lands once, at purchase, and it is the line where a budget built around Finnish varainsiirtovero goes badly wrong.

Transfer tax on buying a home, Finland against Portugal

What you buy	Rate (%)
Finland, asunto-osake		1.5%
Finland, kiinteistö		3.0%
Portugal, non-resident buyer		7.5%

What does Finland tax that Portuguese law does not recognise?

A share certificate. Finnish housing sits inside a company, and Portuguese housing does not.

The Finnish Tax Administration's page for buyers of an asunto-osake sets the tax at 1.5% of the purchase price plus the yhtiölainaosuus, the share of the housing company's own loan attached to the flat. What is taxed is the velaton hinta, the price with that debt counted in, and the tax administration is explicit that it makes no difference whether you clear the loan share at the sale or keep paying it monthly afterwards as rahoitusvastike. Buy a kiinteistö instead, real property such as a house or a summer cottage, and the rate is 3%.

Portugal taxes neither of those, having neither. Article 17.º(10) of the Código do IMT reaches a prédio urbano or a fração autónoma de prédio urbano, an urban building or an autonomous fraction of one. The flat itself is the asset. No company stands between you and it, no yhtiölaina is folded into the asking price, and the shared parts are run by a condomínio that bills you alongside your ownership rather than through it.

Two Finnish reflexes stop working on arrival. Comparing velaton hinta across listings means nothing where no listing carries company debt. And the taloyhtiö balance sheet, the single most informative document in a Finnish purchase, has no counterpart at all: the caderneta predial and the certidão de registo predial describe a property and the charges registered against it, not a company's finances.

Why does a Finnish buyer land on 7.5%?

Tax residence, and nothing else in the rule.

Article 17.º(10), as rewritten by the consolidated Decreto-Lei n.º 97/2026, puts the rate at "always 7.5%" for a non-resident acquiring urban housing and adds that no exemption or reduction applies. That closing phrase costs more than the headline rate, since it takes IMT Jovem, the young buyer relief, off the table along with everything else in the code.

The statute then names three ways out: you were already tax resident under Article 16.º of the personal income tax code; you become tax resident within two years; or you let the property for housing within six months, at a rent capped at 2.5 times the 2026 minimum monthly wage, and keep it let for 36 months inside the first five years.

On the last two, Article 17.º(11) has the Autoridade Tributária cancel the difference against the normal progressive scale, but only "on the interested party's application", and Article 17.º(12) allows six months to make it, running from the day you become resident or the day the tenancy is signed. On a 300,000 euro flat that is 22,500 euro of IMT in play, arithmetic on the published rate. Let the six months run out and it is simply spent.

Finland withdrew one relief in 2024. Portugal withdraws the category.

Finnish buyers have already lived through a smaller version of this.

The Finnish Tax Administration states plainly that the first home exemption from varainsiirtovero ended on 1 January 2024, and that it now survives only where the binding contract was signed before that date. A Finn buying a first home today pays a tax an earlier cohort did not.

Portugal's version is wider in scope. Being non-resident does not remove one relief, it removes the whole class of them. IMT Jovem and every other exemption or reduction in the code are unavailable, whatever the buyer's age, whatever the price, and whether or not it is a first home.

Who files the tax, and who needs a fiscal representative?

In Finland the buyer does it unprompted; in Portugal the tax is assessed and then falls due inside a window.

Verohallinto has the buyer file and pay varainsiirtovero oma-aloitteisesti, on their own initiative, through OmaVero. Portugal assesses IMT and, under Article 36.º as amended by the same decree, allows payment on the day of assessment or within the 30 days after it, where it was previously due at once. Stamp duty rides alongside: PwC Portugal's 2026 tax guide puts Imposto do Selo on the purchase at 0.8%, another 2,400 euro on that 300,000 euro flat.

There is one duty a Finn is spared. The Portuguese tax authority's guidance on fiscal representation says that for residents of an EU country, Norway, Iceland or Liechtenstein, appointing a representante fiscal or enrolling in electronic notifications is always optional, while residents of a third country who own Portuguese property must do one or the other. EU membership settles that question and no other. The 7.5% is a residence test, and it reaches a Finn exactly as it reaches a Briton.

What to settle before you sign

Two questions set the rate, and neither is about the flat: will you be tax resident in Portugal, and will the property be let. The letting route starts its clock the day the tenancy is signed rather than the day you think to ask about it. Worth knowing too that no Portuguese source publishes purchases by buyer nationality, so there is no Finnish figure here for a reason.

We do not give buying or selling advice, and nothing here says whether a Portuguese property is worth buying. The checkable part is short: 7.5% for non-residents, no relief of any kind, three exceptions, and a refund that has to be applied for inside six months. Our companion guide for British buyers in Portugal works through the same decree from outside the EU.
