For a non-resident US citizen selling a property in Spain, the capital gains tax is levied at a flat rate of 19 percent on the net profit of the sale. To guarantee payment, the Spanish government legally requires the buyer to withhold 3 percent of the total purchase price at the Notary and pay it directly to the tax authority as an advance.
The Flat 19% Rate for Non-Residents
When it comes time to sell your Mediterranean investment, understanding your tax liability is crucial for calculating your actual return. There is a widespread misconception online that non-EU citizens, including Americans, must pay a 24 percent tax rate on capital gains. This is incorrect.
While the 24 percent rate does apply to certain types of general income for non-EU residents (such as imputed rental income), the Spanish tax code specifically dictates that capital gains derived from the transfer of assets—like selling a luxury villa in Mallorca—are taxed at a flat rate of 19 percent for all non-residents, regardless of whether they hold an EU or a US passport. If you are a Spanish tax resident, the system changes entirely, and you are taxed on a progressive scale ranging from 19 percent up to 28 percent.
Calculating the True Taxable Gain
The 19 percent tax is not applied to the total sale price of the house; it is applied strictly to the net profit. Calculating this net profit accurately can save you tens of thousands of euros.
The formula is relatively straightforward: Sale Value minus Acquisition Value. However, you are allowed to add various expenses to your original acquisition cost to reduce your taxable gain. You can add the regional Transfer Tax (ITP) you paid when you bought the house, the original Notary and Land Registry fees, and the fees paid to your lawyer.
Most importantly, you can add the cost of major structural improvements. If you bought a finca in Ses Salines and spent 200,000 euros legally adding a new roof, a swimming pool, and an annex, those costs increase your acquisition value, thereby lowering your profit margin. It is absolutely vital that you keep all official invoices (Facturas with VAT included) for these renovations, as the tax authority will not accept estimates or cash receipts.
The 3% Withholding Rule (La Retención)
Because non-residents live outside of Spanish jurisdiction, the tax authority implemented a system to ensure they do not sell their property, take the money, and disappear to the United States without paying their capital gains tax.
By law, the buyer of your property is forced to hold back 3 percent of the agreed purchase price on closing day. The buyer has 30 days to pay this 3 percent directly to the Spanish Treasury. For example, if you sell your villa for 2,000,000 euros, the buyer will only give you 1,940,000 euros at the Notary, sending the remaining 60,000 euros to the tax office in your name.
Claiming a Refund or Paying the Difference
This 3 percent withholding is simply an advance payment. Once the sale is finalized, your lawyer must file the Modelo 210 non-resident tax return within four months to declare the actual capital gain.
If your true tax liability (the 19 percent of your net profit) is greater than the 3 percent that was withheld, you will be required to pay the difference to the Spanish government. However, if your actual tax liability is less than the 3 percent withheld, or if you sold the property at a loss and owe zero taxes, your lawyer will use the Modelo 210 to request a refund of the overpaid amount. The Spanish tax authority is legally obligated to return the excess funds to your bank account, though the process can take several months.
The Myth of Non-Resident Exemptions
American sellers must be aware that the generous exemptions available to Spanish residents generally do not apply to non-residents. If a Spanish resident over the age of 65 sells their primary home, the capital gain is completely tax-free. Similarly, if a resident sells their main home and reinvests the money into another primary residence, the gain is exempt. As a non-resident who uses the property as a second home, you do not qualify for these exemptions and must pay the 19 percent tax on all profits.
