You can sell a home in Spain while tax resident elsewhere. In a standard sale, the buyer withholds 3% of the price attributable to the non-resident seller. This is an advance payment towards Spanish tax on the gain, generally charged at 19%. The two percentages are not separate taxes added together.
This guide is for individual non-resident owners selling a home without a permanent establishment in Spain. It explains what to check before accepting an offer, which payments remain after completion and how to prepare the property documentation.
Tax residence matters more than nationality
Having a Spanish NIE does not make you Spanish tax resident. Nor does holding a foreign passport automatically make you non-resident. If you divide your time between countries, confirm your tax position before estimating the cost of selling.
How the 3% withholding works
The buyer deducts the withholding from the amount payable to the seller and pays it to the Spanish tax authority using form 211 within one month of the transfer. The buyer then provides the seller with proof of payment. This document may therefore be issued after completion.
Where resident and non-resident owners sell together, the withholding applies to the non-residents’ share of the price. It also applies when the sale makes a loss.
How the taxable gain is calculated
Taxable gain = adjusted disposal value − adjusted acquisition value.
Eligible purchase costs, taxes, documented improvements and selling expenses can affect this calculation. Ordinary repairs are not treated as improvements, and interest is excluded from acquisition costs. Previous letting can also require depreciation adjustments.
Keep the purchase and sale deeds, invoices and payment records. Your outstanding mortgage affects the cash available at completion, but repaying the loan does not itself reduce the taxable gain.
Filing form 210 after the sale
The seller reports the sale using form 210. The filing period is the three months following the end of the first month after the transfer. The withholding is credited against the calculated tax: claim any excess back or pay the shortfall.
The relevant date is the transfer date, normally the completion deed date in a standard transaction, rather than a later payment date. Ask your adviser to confirm the exact filing deadline and arrange the return, including where a refund is due.
Example of a sale for 500,000 euros
Illustrative example for one non-resident owner, with no exemptions or reductions. The adjusted acquisition value and eligible costs have already been checked.
- Sale price: €500,000.
- Allowable selling expenses: €20,000.
- Adjusted disposal value: €480,000.
- Adjusted acquisition value: €400,000.
- Taxable gain: €80,000.
- Tax on the gain at 19%: €15,200.
- 3% withholding on €500,000: €15,000.
- Balance payable with form 210: €200.
The buyer would allocate €485,000 to the seller before mortgage repayment, other adjustments or provisions. This is neither the profit nor the final net proceeds. If the calculated tax were €10,000, the excess withholding available to claim would be €5,000.
Local land tax and other selling costs
Plusvalía municipal is a separate local tax on the increase in urban land value. Where no increase is demonstrated under the statutory rules, the transfer is not subject to this tax, although the relevant municipal filing is still required. For a non-resident individual seller, the buyer acts as the substitute taxpayer. Arrange how this will be handled before completion.
Budget for agency fees, legal and tax advice, an energy certificate where required and any mortgage cancellation, power of attorney or documentation work. Request figures including applicable taxes. Keep actual selling costs separate from tax advances and repayment of the mortgage principal.
What UK residents should know
The general Spanish rate on this gain is 19%, including for UK tax residents. Other aspects of the tax position may differ, including reliefs and reporting in the country of residence. Check the applicable double taxation treaty with your adviser before signing.
Documents to prepare
Gather identification and NIE/NIF; the acquisition deed and a current land registry extract; the latest IBI bill and cadastral reference; a community debt certificate where applicable; a registered energy certificate if required; mortgage information; and relevant works and occupation documents. Keep invoices needed for the gain calculation.
A useful first step is to compare the property as it stands with the Land Registry, Cadastre and planning records. Extensions, pools and changes of use may need technical and legal review. The route and timescale depend on the individual file; a certificate alone will not resolve every discrepancy.
