The 3% Retention When Selling Spanish Property in 2026: Why Buyers Withhold It and How to Get It Back

The 3% Retention When Selling Spanish Property: Why Buyers Withhold It and How to Get It Back

If you are a non-resident selling property in Spain, there is one number that will catch you off guard at the notary's table: 3%. That is the portion of the agreed sale price your buyer is legally obliged to withhold from you and pay directly to the Spanish tax authority (Agencia Tributaria, often called Hacienda). It is not a tax in itself — it is a payment on account of your capital gains tax. Understanding it is the difference between a clean exit and a bureaucratic headache that drags on for a year or more.

This guide walks you through what the 3% retention is, why your buyer must withhold it, the Modelo 211 and Modelo 210 filings that follow, and the realistic timeline for getting any refund back into your account in 2026.

What Exactly Is the 3% Retention?

When a non-resident of Spain sells real estate located in Spain, Spanish law obliges the buyer to hold back 3% of the gross sale price and pay it to Hacienda within roughly one month of the deed signing. The buyer is the one legally on the hook — if they hand 100% of the price to a non-resident seller, Hacienda can come after the buyer for the missing 3%. That is why no buyer's lawyer in Spain will let this slide.

A few practical points:

• The 3% is on the deed price, not on your gain.
• It applies to non-resident sellers regardless of nationality — EU, UK, US, Canadian or otherwise.
• It applies whether you are an individual or a non-resident company.
• It does not apply if the seller is a Spanish tax resident (they instead declare the gain in their normal annual income tax return).

The legal basis sits in Spain's Non-Resident Income Tax law (Impuesto sobre la Renta de no Residentes, IRNR). Specific articles and thresholds change periodically, so always confirm the current rules with the Agencia Tributaria or a licensed Spanish asesor fiscal before signing.

Why the Spanish Tax Office Demands It

The logic is straightforward: once a non-resident seller has the money and leaves Spain, collecting capital gains tax becomes very difficult. The 3% retention is Hacienda's guarantee deposit. If your actual capital gains tax bill comes out higher than 3% of the price, you owe the difference. If it comes out lower — or you sold at a loss — you can claim part or all of the 3% back.

Modelo 211: The Buyer's Filing

Within roughly one month of the public deed (escritura pública) being signed before the notary, the buyer must:

1. File Modelo 211 with the Agencia Tributaria, declaring the retention.
2. Pay the 3% to Hacienda.
3. Provide you, the seller, with a stamped copy of the Modelo 211.

That stamped Modelo 211 is one of the most important documents you will ever receive in a Spanish property transaction. Without it, you cannot claim a refund. Make it a contractual condition of the sale that the buyer's lawyer delivers a copy to your lawyer promptly after filing. Do not leave the notary's office without a clear written commitment on this point.

Modelo 210: Your Filing as the Seller

After the buyer files the 211, you then have roughly three months to file Modelo 210 — the non-resident income tax return for the specific transaction. This is where you actually calculate your capital gain (or loss) and either:

• Claim a refund of part or all of the 3%, if your real tax liability is lower; or
• Pay the difference, if your real liability is higher than the retention.

How the Gain Is Calculated

In broad terms, your taxable gain is the transfer value minus the acquisition value, with adjustments:

• Transfer value = sale price minus selling expenses you paid (agent commission, plusvalía municipal if you paid it, legal fees tied to the sale).
• Acquisition value = original purchase price plus the costs you paid when you bought (ITP or VAT, notary, registry, legal fees) plus documented capital improvements (not routine maintenance).

The resulting gain is taxed at a flat non-resident rate that, in recent years, has sat at 19% for EU/EEA residents and a higher flat rate for non-EU residents. Rates and brackets can be adjusted in Spain's annual budget law, so confirm the current 2026 rate with an *asesor fiscal* before you file rather than relying on numbers you read online.

A Simple Worked Example

Suppose you bought a flat in Valencia years ago for €200,000 all-in, and you sell it for €300,000.

• The buyer withholds 3% × €300,000 = €9,000 and pays it to Hacienda via Modelo 211.
• You receive €291,000 at the notary.
• Your gain, simplified, is roughly €100,000 minus deductible costs.
• Your actual non-resident CGT liability might be, hypothetically, around €17,000 — meaning you'd owe an extra ~€8,000 when filing Modelo 210.

Conversely, if you sold for less than you paid (a real loss after costs), your CGT liability is zero, and you can claim the full €9,000 back — but only by filing Modelo 210 with the supporting paperwork.

Documents You Need to Claim a Refund

Get these organised before you sign:

• Stamped Modelo 211 from the buyer.
• Escritura de compraventa of the sale (new deed).
• Escritura de compraventa from when you originally bought.
• Invoices for the original purchase costs (notary, registry, ITP/VAT, legal fees).
• Invoices for capital improvements — proper facturas with your NIE on them, not informal receipts.
• Invoices for sale costs (agency commission, lawyer, energy certificate).
• Receipt of plusvalía municipal payment (the local capital gains tax to the town hall).
• Your NIE and a Spanish bank account, or a foreign IBAN that Hacienda will refund to (allowed in most cases for EU accounts; for non-EU accounts a fiscal representative is often the easier route).

Realistic Timeline for the Refund

This is where expectations need managing. Even when everything is filed correctly:

• Modelo 210 must be filed within ~3 months after the buyer's 211 deadline.
• Hacienda then has, in theory, six months to process the refund.
• In practice, refunds in 2026 often take 9 to 18 months, sometimes longer if there is any query.
• If they exceed the legal deadline, late-payment interest is added to your refund.

Patience and a good Spanish asesor fiscal or gestor are your best assets here.

Common Pitfalls to Avoid

• Not getting the stamped Modelo 211. Without it, your refund claim stalls indefinitely.
• Assuming "no gain = nothing to file." You still need to file Modelo 210 to recover the 3%. Silence is not a refund request.
• Missing receipts for improvements. Cash-paid reforms with no proper invoice cannot reduce your gain.
• Forgetting *plusvalía municipal*. This is a separate municipal tax on the increase in land value, paid to the town hall, and as a non-resident seller it is typically deducted from your proceeds at closing or paid shortly after.
• Using the buyer's lawyer to file your 210. Always use your own independent Spanish lawyer or *asesor fiscal — their job is to protect your* refund.
• Closing a Spanish bank account too early. Keep one open until the refund lands.

Short FAQ

Can the 3% retention be waived? Generally no for non-resident sellers. A tax-residency certificate proving you are a Spanish tax resident at the time of sale is the main way to avoid it.

What if the buyer refuses to file Modelo 211? They are exposing themselves, not you, to Hacienda's claim — but it still blocks your refund. Build delivery of the stamped 211 into the sale contract.

Does this apply if I sell at a loss? Yes. The retention still applies up front; you reclaim it via Modelo 210.

Do US and Canadian sellers face a different rate? The 3% retention is the same. The final CGT rate applied on the gain depends on EU vs non-EU status and applicable double-tax treaties — confirm with a Spanish tax adviser.

Spanish tax law, rates and procedural deadlines change regularly. Treat this guide as orientation, not advice — confirm the current rules with the Agencia Tributaria and a licensed Spanish abogado or asesor fiscal before signing anything in 2026.
