Selling a Property in Spain as a Non-Resident: The 3% Withholding Tax

What is the 3% withholding tax when selling a property?

When an owner who does not pay taxes as a tax resident in Spain decides to sell a house as a non-resident, the legislation establishes a withholding mechanism at source. This procedure obliges the buyer to deduct 3% of the total amount agreed in the public deed and pay it to the Public Treasury via the State Tax Administration Agency (AEAT).

The main purpose of this measure is not to apply a final tax in itself, but rather to make an advance payment towards the final IRNR settlement. Since the seller does not have their tax residence in the country, the Tax Office uses this precautionary deduction to ensure the transaction does not go untaxed once the transfer is completed.

It is important to remember that the legal responsibility to withhold and pay this tax rests exclusively with the buyer, regardless of whether they are an individual or a legal entity, resident or non-resident. If the buyer fails to make the payment on time, the transferred property will be secondarily liable for paying the amount due.

The step-by-step procedure: Form 211 and Form 210

To manage the tax operations accurately when selling a property as a non-resident, two official forms regulate the deadlines and obligations of both parties after the execution of the public deed:

1. Payment by the buyer using Form 211

During the signing before the notary, the buyer deducts 3% of the total agreed price. From that date, they have an exact deadline of one month to complete and pay this amount using Form 211. Following formal submission, the buyer must provide a stamped copy of this document to the seller so that the seller can prove the tax withheld before the Tax Office.

2. Settlement by the seller using Form 210

Once the previous form has been submitted, the seller has a statutory period to regularise their actual tax situation. They must submit Form 210 within three months following the deadline the buyer had to make the payment (making a maximum of four months from the date the sale was completed).

By submitting Form 210, it is determined whether the transaction generated a capital gain or loss, calculating the final tax due and adjusting it against the 3% advance payment previously made.

Calculation of capital gains and applicable taxes

The initial 3% withholding does not necessarily represent the final tax to be paid. The definitive tax liability depends exclusively on the net gain obtained by the seller. To determine the capital gain when selling a house as a non-resident, the difference between the transfer value and the acquisition value is taken into account:

• Transfer value: This is calculated starting from the sale price specified in the deed, deducting the costs inherent to the transfer borne by the seller, such as estate agency fees, legal advice fees, and the payment of Municipal Capital Gains Tax (plusvalía municipal).
• Acquisition value: This is obtained by adding all direct taxes associated with the purchase (VAT or Property Transfer Tax), notary fees, land registry fees, and documented costs of structural renovations or extensions to the original purchase price. From this total, accumulated depreciation is deducted if the property was rented out.

The IRNR tax rate of 19% is applied to the calculated net capital gain, applicable both to tax residents in the European Union, Iceland, and Norway, and to those residing in third countries outside the EU.

Scenarios following the IRNR tax settlement

Once the 19% rate on the actual profit is calculated against the 3% withheld during the transfer, three distinct financial scenarios may arise:

1. Refund claim: If the net profit made is small and the resulting 19% tax is lower than the amount withheld via Form 211, the owner has the right to claim a refund for the remaining balance.
2. Capital loss: When the property is sold for an amount lower than the computed acquisition value including all eligible expenses, no taxable gain arises. In this case, the seller can request a full refund of the 3% withheld from the Tax Agency.
3. Additional tax payment: If the property has appreciated significantly in value since its acquisition, the tax liability at 19% will be higher than the 3% withheld at the notary. The taxpayer must pay the outstanding difference to AEAT when submitting Form 210.

Documentation and deadlines for the 3% refund

When the outcome of Form 210 involves a partial or full refund of the balance withheld when selling a house as a non-resident, the Tax Agency opens a verification procedure to confirm the accuracy of the figures provided. To prevent delays in receiving the refund, it is essential to gather the following supporting documents:

• Copy of the public purchase and sale deeds.
• Original invoices for agency commissions, legal and professional fees, notary fees, registry fees, and taxes paid in both transactions.
• Invoices and bank payment receipts for building works or improvements made to the property that increased its acquisition value.
• Proof of payment of Form 211 provided by the buyer.
• Bank account ownership certificate for the account where the refund should be paid (this can be an overseas account if it meets account holder identification requirements).

The Tax Office has a statutory period of six months from the end of the submission deadline or from the date of the application to make the refund. If there are delays not attributable to the taxpayer beyond this period, AEAT will pay the amount due along with statutory interest for late payment.

Exceptions to the withholding requirement

Deducting the withheld amount is not mandatory in all property transactions. There are specific legally defined cases where the 3% withholding tax does not apply:

• When the transferred property is contributed to a commercial company that maintains its tax domicile in Spanish territory.
• In non-lucrative transfers (such as gifts or inheritances), which are subject to Inheritance and Gift Tax.
• If the seller proves, by means of an official certificate issued by the Tax Agency, that they pay their taxes in Spain subject to Corporate Income Tax or the general IRPF regime.

Tax planning in high-value property transactions

In transactions within the market for prime estates and high-end residences, the amount corresponding to 3% reaches substantial sums. Correctly managing Form 210 and substantiating every improvement or deductible expense with documentation allows for tax optimization and cash flow efficiency.
