Tax Guide for Swiss Buyers in Spain: Everything You Need to Know Before Investing

Dreaming of owning a property under the Spanish sun? As a Swiss resident, buying real estate in Spain is an exciting life project — but it comes with important tax implications that are worth understanding before you sign anything. Between Swiss and Spanish regulations, the rules aren't always straightforward. This guide walks you through the key taxes and obligations, so you can move forward with confidence.

1. The Switzerland–Spain Double Taxation Agreement

The good news: Switzerland and Spain have signed a Double Taxation Agreement (DTA), originally in force since 1967 and updated in 2013. Its purpose is to prevent you from being taxed twice on the same income in both countries.

In practical terms, the DTA defines which country has the right to tax what:

• Rental income generated by a property in Spain is generally taxable in Spain.

• Capital gains from the sale of Spanish real estate are also taxable in Spain.

• Switzerland may still take these incomes into account to calculate your overall tax rate (exemption with progression method).

It is therefore essential to declare your Spanish property to your Swiss cantonal tax authority, even if the tax itself is paid in Spain.

2. Taxes Due at the Time of Purchase

Even before earning any rental income or reselling, the purchase itself triggers tax costs in Spain:

For a new-build property:

• VAT (IVA): 10% of the purchase price for residential new-builds

• Stamp duty (AJD): between 0.5% and 1.5% depending on the autonomous region

For a resale property:

• Property Transfer Tax (ITP): between 6% and 10% depending on the region (in Valencia and Murcia, typically 8% to 10%)

These taxes come on top of notary fees, land registry costs, and legal fees (approximately 1% of the purchase price). Budget a total of 12% to 15% of the purchase price in additional costs.

3. Non-Resident Income Tax (IRNR)

If you live in Switzerland and your Spanish property is a second home (you spend fewer than 183 days per year there), you are considered a non-resident for Spanish tax purposes and subject to the IRNR (Impuesto sobre la Renta de No Residentes).

a) If the property is not rented out:

Spain imposes a deemed rental income calculated on the cadastral value of the property. The rate is 19% for EU/EEA residents — and Swiss nationals benefit from this same rate thanks to bilateral agreements between Switzerland and the EU.

Example: cadastral value of €100,000, deemed taxable income = 1.1% or 2% depending on the year of cadastral revision, i.e. €1,100 to €2,000, taxed at 19%.

b) If the property is rented out:

Rental income is taxed in Spain at 19% on gross income. Swiss residents, thanks to their assimilated European status, may be able to deduct certain expenses such as mortgage interest, maintenance costs, and local taxes.

The declaration is filed quarterly using Form 210.

4. Capital Gains Tax on Resale

When you sell your Spanish property, two separate taxes apply:

National Capital Gains Tax (Ganancia Patrimonial)

The gain (difference between the sale price and the original purchase price, including acquisition costs) is taxed at 19% for European non-residents.

In addition, the buyer is required to withhold 3% of the sale price and pay it directly to the Spanish tax authorities as an advance on your capital gains tax. You will receive a refund if the actual tax owed is lower.

Municipal Capital Gains Tax (Plusvalía Municipal)

This is a local tax based on the increase in the cadastral value of the land since your purchase. The amount varies by municipality and length of ownership. Following a 2021 reform, this tax is only due if you actually make a profit on the sale.

5. Wealth Tax (Impuesto sobre el Patrimonio)

Spain levies a wealth tax on non-residents for assets located in Spain. An allowance of €700,000 per person applies.

If the value of your property exceeds this threshold, you will need to file an annual declaration (Form 714). The rate is progressive, ranging from 0.2% to 3.5% depending on the value of the assets.

Note: since 2022, a solidarity tax on large fortunes (2% above €10M) also applies at the national level.

6. The NIE: An Indispensable First Step

Before any purchase, you will need to obtain a NIE (Número de Identificación de Extranjero) — Spain's tax identification number for foreign nationals. It is mandatory for signing at the notary, opening a Spanish bank account, and paying your taxes.

RBplace guides you through this process, which can seem daunting at first, to make it as smooth and stress-free as possible.

7. Our Practical Tips

• Consult a tax lawyer specialised in Spanish law and international tax treaties before signing any purchase agreement.

• Declare your Spanish property in Switzerland: your canton and municipality must be informed for the calculation of your wealth and income tax.

• Plan your cash flow carefully: the IRNR is due every year, even if the property remains empty.

• Keep all purchase and renovation invoices: they will reduce your taxable capital gain when you eventually sell.

Conclusion

Spanish property taxation may seem complex from a Swiss perspective, but it is entirely manageable with the right preparation and the right advisors. The double taxation agreement provides a solid protective framework, and the rates applied to European residents are reasonable.
