Buying Property in Sweden as a Spanish Buyer: Tax, Modelo 720, ID

A Swedish flat becomes yours with one signature. The tax paperwork it creates in two countries, Sweden and Spain, lasts as long as you own it.

If you stay tax resident in Spain, Sweden taxes the rent and the sale gain first. Spain taxes them too, then credits the Swedish tax under the 1976 convention between the two countries. The home goes on Modelo 720 once your foreign property passes 50,000 euro. Since July 2026, registering a Swedish house also needs a Swedish ID number.

This guide covers that paper trail, which is the part a Spanish buyer cannot learn from a viewing.

Which tax treaty applies between Spain and Sweden?

The 1976 convention does. The Agencia Tributaria, Spain's tax agency, lists it as the income and capital tax convention signed in Madrid on 16 June 1976 and published in the Boletín Oficial del Estado on 22 January 1977.

Two articles matter for a home. The Agencia Tributaria's guide for Spanish residents with Swedish income summarises them:

• Article 6. Income from real estate located in Sweden may be taxed in both Spain and Sweden.
• Article 13.1. Gains from selling real estate located in Sweden may be taxed in both countries.

In both cases the Spanish resident claims Spain's deduction for international double taxation, the deducción por doble imposición internacional. So you pay in Sweden and declare in Spain, and the tax already paid in Sweden reduces the Spanish bill instead of being added to it.

What does Sweden tax a Spanish owner on?

Sweden taxes the rent, the sale gain and the registration. Skatteverket, the Swedish Tax Agency, says on its page for owners of Swedish property living abroad that you must file a Swedish tax return if you own property there and have rented it out or sold it. The 2026 deadline was 4 May. Residents abroad are not charged a late filing penalty if the return arrives by 1 June.

• Letting a private home. Skatteverket's rules for owning property allow a deduction of 40,000 kronor per property plus 20% of the rent. The surplus is taxed at 30%.
• Selling. For a private home, Skatteverket taxes 22/30 of the profit at 30%. That works out to 22% of the gain. The same fraction applies to a bostadsrätt, the Swedish cooperative flat.
• Registering a house. Lantmäteriet, the land registration authority, charges 1.5% of the price plus 825 kronor for lagfart, the title registration. A new pantbrev, the mortgage deed, costs 2% of its amount plus 375 kronor.

One-off registration cost on a 4,000,000 kronor purchase

What you buy	Cost ( kr)
Bostadsrätt (cooperative flat)		0 kr
House: lagfart		60,825 kr
House: new 3,000,000 kr pantbrev		60,375 kr

A bostadsrätt carries no stamp duty at all. The transfer is noted by the cooperative, not by Lantmäteriet. Spain has no equivalent tenure. A Spanish resale flat is real property and pays the Impuesto sobre Transmisiones Patrimoniales (ITP), the regional transfer tax on resale homes.

Modelo 720: does a Swedish home have to be declared in Spain?

Yes, once it crosses the threshold. Modelo 720 is Spain's information return on assets held abroad. The Agencia Tributaria's Modelo 720 FAQ treats real estate located abroad as its own block of information. Its worked example shows that foreign property valued at 45,000 euro in total needs no declaration, and the same property at 55,000 euro does.

After the first filing, the agency's FAQ on how often to file says you file again only when the block's joint value has risen by more than 20,000 euro. It also lists a transfer or cancellation of the asset as a reason to file again.

Modelo 720 applies to Spanish tax residents. A Spaniard who has already moved to Sweden and pays tax there is outside it.

From NIE to samordningsnummer: the ID rule that changed in July 2026

In Spain a foreigner cannot buy without an NIE, the Número de Identidad de Extranjero. Your DNI already does that job for you at home. In Sweden you are the foreigner, and since July 2026 the rule for houses is just as strict. Lantmäteriet states on its page for foreign buyers that transfers from 1 July 2026 need a Swedish personnummer or samordningsnummer (coordination number) for the new owner. Without one, the lagfart application is held dormant and costs extra fees.

• How to get one. Skatteverket's coordination number page says you can apply yourself with form SKV 7540. You then visit a service centre in person with a passport or national identity card for an ID check.
• How long it takes. Skatteverket's processing times show an individual application can wait up to 12 weeks before a caseworker even picks it up (read on 21 September 2026).
• How long it lasts. The number stays active for five years and can then be reactivated.

Our lagfart and coordination number guide covers the transition rules in full.

Where the Spanish reflexes mislead

Three habits from a Spanish purchase do not carry over:

• No notario. The contract is drawn up by a registered fastighetsmäklare, the estate agent, supervised by Fastighetsmäklarinspektionen (FMI), the estate agent regulator.
• No arras. Under chapter 4, section 1 of the Jordabalken, the Land Code, a house is bought through a written deed signed by seller and buyer. An accepted bid is not a purchase.
• No comunidad certificate. The risk you check is not the seller's unpaid fees. It is the cooperative's own debt, which you carry through the monthly fee. Our guide to a BRF's interest rate sensitivity shows how to read that in the årsredovisning, the annual report.

Moving the money from a Spanish bank

The agent will ask where the money comes from. Under the anti-money-laundering rules, FMI's customer due diligence guidance requires the agent to collect information on how the purchase will be financed, from buyers as well as sellers. Enhanced measures apply to customers established outside the European Economic Area (EEA). A Spanish resident is inside it, but will still be asked. Bank statements from the Spanish account, the deed of anything sold to raise the money and any loan agreement are the kind of documents FMI says an agent may need to see.

If you borrow in Sweden, Finansinspektionen (FI), the financial supervisor, raised the loan cap for a home purchase from 85% to 90% on 1 April 2026. That is the legal ceiling. Each bank sets its own terms for borrowers whose income is in euro.

What the sources support

We do not give buying or selling advice, and nothing here says whether a Swedish property is worth buying. The sources support four checkable points. The 1976 convention lets both countries tax Swedish rent and gains, with a Spanish credit. Sweden taxes rental surplus at 30% and a home sale at an effective 22%. Modelo 720 applies above 50,000 euro. A coordination number is now needed before a house can be registered.

If you are also weighing Spain from the other side, our guide for Swedish buyers in Spain runs the same comparison in reverse. AiMYNDi reads a Swedish listing and the cooperative's årsredovisning and explains them in Spanish. You can see an example of what a report looks like first.
