Buying a House in Portugal as a Danish Buyer: No Permit, 7.5% Tax

Denmark decides who is allowed to buy a Danish home, and asks the Ministry of Justice to sign off when the buyer has not lived there. Portugal lets anyone buy, then charges a non-resident 7.5% for it.

The two countries restrict foreign buyers in opposite currencies: Denmark spends permission, Portugal spends money. Decreto-Lei n.º 97/2026 fixes the Portuguese rate at 7.5% for a non-resident buyer of urban housing, cancels every relief behind it, and refunds the difference in two situations if the application reaches the tax office inside six months.

The Portuguese charge is called Imposto Municipal sobre as Transmissões Onerosas de Imóveis, IMT for short, and the município collects it when ownership changes. It screens nobody, which is exactly why it ends up being the whole story for a Danish buyer.

What the purchase itself is taxed at

Where you buy, and as what	Rate (%)
Portugal, non-resident buyer		7.5%
Portugal, resident, lower bands		0.0%
Sweden (stämpelskatt)		1.5%
Denmark (tinglysningsafgift)		0.6%

Which country actually restricts a foreign buyer?

Denmark does, by permission. Civilstyrelsen, the agency under the Danish Ministry of Justice that handles these cases, states that if you do not have bopæl in Denmark in the sense of erhvervelsesloven, or have not had bopæl there for at least five years, you generally need its permission to acquire real property in the country.

The bar rises for a holiday property. Civilstyrelsen splits its guidance between a helårsbolig, a year round home, and a sekundærbolig, a secondary one, and its own heading on the secondary case reads that permission to buy one requires "særlig stærk tilknytning til Danmark", a particularly strong connection to Denmark. A Dane who has moved abroad meets that machinery on the way back in.

Portugal runs no such gate. Article 17.º(10) is a rate, not a permission, and a foreign buyer of a Portuguese home needs no ministry to approve the purchase. What the buyer meets instead is a price, and it is the same price for a Dane, a Brazilian and a Portuguese citizen living in Copenhagen.

What does Article 17.º(10) charge for, and what is the six months?

It charges for non-residence. The consolidated text sets the rate at "always 7.5%" on urban housing bought by a non-resident, "no exemption or reduction applying", and the second half of that phrase is where most of the money hides: reliefs are withdrawn rather than trimmed, IMT Jovem for young buyers along with the rest.

Three situations escape the flat rate, and two of them pay money back:

• Portuguese tax residence was in place already, under Article 16.º of the personal income tax code.
• It arrives inside two years of the acquisition.
• The property is let for housing within six months, at or below the moderate rent ceiling that Article 2.º(2) puts at 2.5 times the 2026 minimum monthly wage, and stays let 36 months during the first five years.

Article 17.º(11) has the Autoridade Tributária cancel the excess "on the interested party's application", and Article 17.º(12) allows six months from becoming resident or from signing the tenancy. The refund is a claim, not a credit, and an unclaimed one simply expires.

The clocks written into Article 17.º

What the statute requires	Deadline (months)
Apply for the refund within		6months
Or sign a tenancy within		6months
Or become tax resident within		24months
Keep it let for at least		36months

What does registration cost in Denmark?

Six tenths of one per cent plus a fixed amount, and it buys an entry in a register rather than settling a tax on the deal.

The Skatteministeriet rate table for the tinglysningsafgiftslov puts registering a change of owner at 0.6% of the transfer sum plus a fixed 1,850 kroner. Watch that fixed figure. The 1,825 kroner quoted almost everywhere as the tinglysningsafgift belongs to registering a mortgage, not a transfer, and secondary sources contradict each other only because they are describing two different charges.

Scale it. On a 300,000 euro apartment the Portuguese rate takes 22,500 euro, where 0.6% would take 1,800 euro plus the fixed amount. Both totals are worked out from the published rates.

The other Danish six, and why it does not travel

Six business days, and it is a protection rather than a deadline.

Denmark's consumer protection act on the acquisition of real property gives a private buyer a right of withdrawal for six business days after the agreement, on payment of 1% of the purchase price. It works on its own; the buyer does nothing to earn it. The Portuguese six months is the opposite shape. It grants nothing, protects nobody, and runs out unless a document is filed. Reading the two as similar because both are counted in sixes is the fastest way for a Danish buyer to lose five figures.

What does EU membership settle?

Paperwork and time in the country, and nothing at all on the rate.

The Autoridade Tributária's guidance on fiscal representation treats residents of an EU country, Norway, Iceland or Liechtenstein as the group for whom appointing a representante fiscal stays optional, and everyone else as third country residents who must appoint one once they have a tax relationship in Portugal. Owning a home creates one. Schengen membership separately lifts the 90 days in any 180 short stay rule from a Danish owner.

Both concessions answer questions about status. The 7.5% answers a question about residence, and a Dane who keeps their tax home in Denmark pays it in full.

Where the numbers stop

Nobody counts Danish buyers of Portuguese homes. Portugal publishes residence permits by nationality, a count of people who moved rather than people who bought, so no source supports a figure for Danish ownership there.

We do not give buying or selling advice, and nothing here says whether a Portuguese property is worth buying. Everything the sources carry fits in a line: no permission needed to buy, 7.5% flat for non-residents, reliefs withdrawn rather than reduced, three exits, and a refund that expires six months after you qualify. Our guide to buying in Spain as a Danish buyer covers a market that asks a foreign buyer neither permission nor a higher rate.
