Danish buyers' guide to buying property on the Costa del Sol — 2026

This guide is written for Danish nationals buying property on the Costa del Sol in 2026. Danish buyers face a distinctive and critical tax situation that sets them apart from all other EU buyers: Denmark terminated its double taxation agreement with Spain in 2009, and no replacement treaty is currently in force. This creates the potential for genuine double taxation on rental income, capital gains, and inheritance in a way that does not affect German, Dutch, or Swedish buyers who have functioning treaty protection. Understanding this clearly before purchasing is essential. This guide explains the practical implications, the 19% Spanish IRNR framework, the minimal currency risk from the DKK/EUR peg, Danish inheritance tax, and the buying process.

EU free movement — unrestricted entry and residence

Denmark is a member of both the EU and the Schengen Area. Danish nationals have full EU freedom of movement in Spain — no 90-day limit, no visa requirement, and no income threshold for visits of any duration. If you plan to stay more than three months continuously, you register as an EU resident at the Oficina de Extranjería, presenting your Danish passport or national identity card, proof of modest financial means, and health insurance. The registration certificate is issued promptly. After five years of continuous legal residence, permanent residency follows automatically.

The NIE

An NIE (Número de Identificación de Extranjero) is required before signing the private purchase contract. Danish nationals obtain this in Spain at a Comisaría de Policía Nacional, or through the Spanish consulate in Denmark. Allow two to four weeks as an EU national.

No double taxation treaty — the critical distinction for Danish buyers

This is the most important section of this guide. Denmark unilaterally terminated its double taxation agreement with Spain with effect from 1 January 2009. The termination was driven by a dispute over Denmark's right to tax pension payments to Danish retirees who had relocated to Spain. No replacement treaty has been concluded, and no new agreement is currently in force between the two countries.

What this means in practice — without a DTA, Spain and Denmark each apply their domestic tax law to property-related income and gains independently. There is no treaty mechanism preventing both countries from taxing the same rental income or capital gain. Danish domestic law may provide unilateral credit relief for foreign taxes paid in some circumstances, but this is not guaranteed, it must be actively claimed, and it does not provide the same legal certainty as a bilateral treaty.

Rental income — Spain taxes rental income from Spanish property at 19% IRNR for EU non-residents, on net income after allowable expenses. Denmark, as a country with a global income taxation principle, also taxes Danish residents on their worldwide income. Without a treaty, the Danish tax authority (SKAT) may assess rental income from Spanish property as part of Danish taxable income, potentially at Danish marginal rates. Danish domestic law does permit a credit for foreign taxes paid, but the mechanism is less reliable than treaty-based relief and requires Danish tax advice for each specific situation.

Capital gains — Spain applies 19% CGT to the gain on sale for EU non-residents (3% withheld by buyer at completion). Without a treaty, SKAT may also seek to tax the same gain as part of Danish worldwide income. Danish capital gains on property can reach up to 42% for individuals under domestic rules. Whether a full credit is available for the Spanish CGT paid against the Danish liability depends on Danish domestic law at the time of sale and the specific taxpayer's circumstances.

The unambiguous conclusion — Danish buyers must engage a qualified Danish tax adviser experienced in cross-border Spain-Denmark matters before purchasing Spanish property. The combination of Spanish IRNR and potential Danish domestic taxation without treaty protection makes the total tax burden less predictable than for German, Dutch, or Swedish buyers. This does not mean Danish buyers should not purchase in Spain — many do, successfully — but it means professional tax planning from the outset is not optional, it is essential.

Spanish IRNR — the Spanish side is clear

Regardless of the DTA situation, the Spanish obligations are clear and apply to all EU non-residents uniformly. Danish nationals as EU residents pay IRNR at 19% — the EU rate. For properties not rented out, the imputed income (renta imputada) is calculated as 1.1% of the cadastral value (or 2% if not reviewed in the last decade), taxed at 19%, declared annually on Form 210 by 31 December of the following year. For rented properties, allowable expenses (mortgage interest, IBI, community fees, insurance, maintenance, depreciation at approximately 3% of construction value) are deductible before applying the 19% rate. Capital gains on sale are taxed at 19%, with 3% withheld by the buyer at completion (Form 211) and a final settlement on Form 210 within four months of sale.

Currency — the DKK/EUR peg and minimal exchange risk

Denmark uses the Danish krone (DKK), not the euro. Unlike Swedish or British buyers, however, the DKK is not a freely floating currency. Denmark participates in the European Exchange Rate Mechanism II (ERM II) and maintains a formal central rate of approximately DKK 7.46 per euro, with a permitted fluctuation band of ±2.25%. In practice, the Danish National Bank has held the rate within a far narrower band for decades. The DKK/EUR peg has been one of the most stable currency anchors in Europe.

This means Danish buyers have minimal practical currency risk compared with Swedish (SEK/EUR), British (GBP/EUR), or other non-eurozone buyers. The effective purchase cost in DKK terms is highly predictable from reservation through to completion. While the peg is not legally permanent — it is a policy commitment, not constitutional — it has been maintained consistently since 1982 and disrupting it would be a major policy shift. Danish buyers should be aware of this distinction while treating it as effectively stable for property purchase planning purposes.

Purchase taxes and costs

New-build properties: IVA at 10% of purchase price. Resale properties: ITP in Andalusia at a flat 7%. AJD stamp duty at 1.2% in Andalusia on the mortgage deed if financing. Independent legal fees 0.5–1.0% plus IVA. Notary and registry approximately 0.5–1.0%. Mortgage arrangement if financing 1.0–2.0%. Budget 12–14% of the purchase price as total ancillary cost for a financed new-build.

Danish inheritance tax (boafgift) and Spanish succession

Denmark applies inheritance tax (boafgift) when a deceased person was domiciled in Denmark. For 2026: spouses and registered partners inherit tax-free. Children, step-children, and parents pay 15% on assets above approximately DKK 392,300 (~€53,000). Siblings, other relatives, and unrelated beneficiaries pay 15% plus a supplemental levy of 25% (tillægsboafgift), making the combined rate 36.25%. Without a DTA, there is no bilateral mechanism to prevent both Danish and Spanish inheritance taxes applying to the same asset.

In Andalusia, however, Spanish inheritance tax for direct-line beneficiaries is highly favourable: spouses, children, and parents each benefit from a €1,000,000 tax-free allowance per beneficiary, with a 99% reduction on the remaining quota. The practical Spanish inheritance liability is very low. Danish boafgift at 15% for children is modest for direct family. In combination, most Danish families face a manageable total inheritance burden on a Costa del Sol property. For larger estates or more distant beneficiaries, professional advice in both jurisdictions is important.

A Spanish will (testamento) is recommended. EU Succession Regulation 650/2012 applies — Danish nationals may elect Danish law to govern succession. A Spanish will ensures efficient estate administration without Danish executors managing a Spanish probate process.

The buying process

1. Reservation (reserva) — a refundable deposit of €5,000–€15,000 holds the property. Retain an independent Spanish property lawyer — given the tax treaty gap, it is particularly important that your legal team understands the Denmark-Spain no-treaty position.

2. Private purchase contract (contrato privado de compraventa) — the binding contract. For off-plan purchases, all stage payments must be covered by an individual aval bancario (bank guarantee) under Spanish law.

3. Completion (escritura pública de compraventa) — signed before a Spanish notario. Your lawyer attends or holds a power of attorney.

4. Registration — title registered at the . Typically four to eight weeks.

Running costs

IBI — approximately €600–€1,200 per year for a standard Marbella apartment. Community fees — €100–€200 per month on a standard urbanisation. Annual IRNR declaration on Form 210 — a Spanish gestor handles this for €100–€200 per year.

The key recommendation for Danish buyers

Before signing anything, engage a Danish tax adviser with specific experience in cross-border Denmark-Spain property ownership. The absence of a DTA means the Danish domestic treatment of Spanish rental income and capital gains requires professional assessment based on your specific Danish tax position, income level, and circumstances.
