Buying an apartment on the Turkish coast does not end your relationship with the Danish tax authority. As long as you remain fully tax-liable in Denmark, SKAT treats your Turkish home as part of your worldwide tax picture. The deed sits in the Turkish land registry, the keys are in Alanya or Antalya, but the reporting duty stays in Denmark. This guide explains what SKAT expects from you every year and what happens if you let those duties slide.
Why SKAT needs to know about your Turkish property
Denmark taxes its residents on global income and global assets. That principle is the reason a flat in Turkey matters to a tax office in Copenhagen. SKAT is not interested in the property because it is Turkish; it is interested because you are Danish-resident, and Danish residence carries a worldwide disclosure duty. Once you understand that, the individual rules below stop feeling arbitrary and start to look like one coherent system.
Skattekontrolloven § 8 P: reporting foreign property
The core duty lives in the Danish Tax Control Act. Skattekontrolloven § 8 P requires Danish residents to inform SKAT when they acquire, dispose of, or change the use of real property abroad, Turkey included. In practice this means your purchase must surface on the selvangivelse for the income year in which you took ownership. A companion provision, § 11, gives SKAT the authority to exchange information with foreign tax administrations, including Turkey's Gelir Idaresi Baskanligi (GIB), under the 1981 Denmark-Turkey double-taxation agreement.

How CRS automatic exchange works
Many owners assume that what happens in Turkey stays in Turkey. It does not. Both Turkey and Denmark are participating jurisdictions in the OECD Common Reporting Standard (CRS). Turkish banks and, increasingly, property and financial registries report account balances and transactions to GIB, which forwards the data to SKAT automatically. The consequence is blunt: SKAT may already hold information about your Turkish bank account and rental flows before you file anything. Non-disclosure is therefore not a gap SKAT has to discover by chance; it is a mismatch the system surfaces on its own.
Ejendomsvaerdiskat: when it applies and when it does not
Denmark levies a property-value tax, ejendomsvaerdiskat, on residents who own a home abroad for personal use, including a Turkish holiday property. The rate is 0.92% of the property value up to DKK 9.2 million and 3% on the portion above that threshold (rates effective from 2024). The value is your own good-faith estimate of the market value in DKK each year, since there is no Turkish valuation SKAT automatically accepts.
The important exemption: if the property is rented out for the full year on commercial terms, ejendomsvaerdiskat falls away for that year. The tax burden shifts instead to the rental income, which is taxed as capital income. You cannot, however, claim both treatments at once for the same period.
Rental income and the double-taxation agreement
When you let your Turkish flat, Turkey has the first taxing right as the source state under Article 6 of the DK-TR double-taxation agreement. Turkish withholding is collected by GIB. Denmark then taxes the same net rental income but applies the credit method under ligningsloven § 33, allowing the Turkish tax already paid to be offset. In most cases where Turkish tax was genuinely paid, the additional Danish tax nets to roughly zero, but the income still has to be declared.
The annual selvangivelse: deadline and what to declare
For most wage earners the selvangivelse deadline is 1 May each year (1 July for those filing through an approved accountant). Foreign property is reported through TastSelv Borger under foreign income and the ejendomsvaerdiskat section. On the first return after purchase, declare the acquisition price in DKK, the date of acquisition (the TAPU transfer date), the address, and your ownership share. Each year thereafter you confirm the property value for ejendomsvaerdiskat and report any rental income.
What Danish banks and brokers must report
Your disclosure is not the only channel. Danish banks and financial intermediaries report account movements and certain foreign holdings under the same automatic-exchange framework. Mortgage debt secured on the Turkish property also feeds into your Danish wealth picture and must be disclosed; interest on foreign mortgage debt is generally deductible in Denmark as capital income.
Capital gain on sale in Denmark
Here is the rule that surprises most sellers. Turkey exempts capital gains after five years of ownership, but that exemption does not exist in Danish law. A gain on the sale of your Turkish property is fully taxable in Denmark and must be declared on the selvangivelse for the year the sale completes. The gain is calculated as the sale price in DKK minus the acquisition cost in DKK (including improvements), each converted at the exchange rate on its respective date.
The 10-year reassessment window
SKAT can ordinarily reopen a tax assessment three years back. If an omission is judged deliberate or grossly negligent, that window extends to ten years, alongside back-tax, surcharges (currently around 7.2% per year), and in serious cases penalties. Voluntary correction before SKAT acts generally earns more lenient treatment.
Practical advice: get a Danish revisor
The Turkish TAPU registry, GIB rules, and SKAT requirements intersect in ways that are easy to get wrong. A Danish revisor or tax adviser experienced in foreign property is a worthwhile investment, particularly if you hold the property through a Turkish company, which changes the Danish tax treatment substantially. The cost of advice is almost always smaller than the cost of a ten-year reassessment.
