The Buyer's 3% Withholding Duty in Spain: How Modelo 211 Works When You Buy from a Non-Resident Seller

When you buy a property in Spain from a non-resident seller, Spanish law makes you, the buyer, a withholding agent. You must retain 3% of the agreed sale price, pay it to the Agencia Tributaria via Modelo 211 within one month of the public deed, and give the seller a retention certificate. This is your personal tax obligation under Article 25.2 of the IRNR Law (Real Decreto Legislativo 5/2004), not the seller’s. If you fail to withhold or fail to pay, the property is encumbered and you face personal liability under the Ley General Tributaria. Your lawyer should handle the filing, but you are the party AEAT holds responsible.

What is the buyer’s 3% withholding duty under Modelo 211?

The buyer’s 3% withholding duty is a mandatory payment on account that the purchaser of Spanish real estate from a non-resident seller must calculate, retain from the sale price, and deposit with the Agencia Tributaria. Article 25.2 of the consolidated text of the Non-Resident Income Tax Law (Real Decreto Legislativo 5/2004, de 5 de marzo) states that the acquirer of a property from a non-resident without a permanent establishment must withhold and pay 3% of the agreed consideration as a payment on account of the tax corresponding to the non-resident transferor. The mechanism exists because a non-resident seller is outside Spain’s standard collection reach, so the law takes the cash at source through the buyer.

The buyer files Modelo 211, the self-assessment form approved for this purpose by Orden EHA/3316/2010, within one month of the date of transfer (the deed date). The AEAT instructions confirm the one-month deadline runs from the transmission date, not the payment date. The buyer pays the 3% into the restricted AEAT account and receives a receipt. The buyer then delivers the “copy for the non-resident transferor” (the certificado de retencion) to the seller, who uses it to justify the payment on account when filing their own Modelo 210 capital gains declaration. The buyer keeps the “copy for the purchaser” as proof of compliance.

Step	Who acts	Deadline	What happens
Retain 3% of sale price	The buyer	At the notary, on the deed date	Buyer pays seller 97%, holds 3%
File Modelo 211 and pay 3% to AEAT	The buyer	Within 1 month of the deed	Buyer deposits the 3% with the tax authority
Deliver certificado de retencion to seller	The buyer	With the Modelo 211 filing	Seller gets proof to deduct on Modelo 210
Seller files Modelo 210 (IRNR capital gains)	The seller or their representative	Within 4 months of the deed	Seller reconciles 3% against the 19% IRNR due

What is the buyer’s personal liability if the withholding is not paid?

The buyer’s personal liability is the core of why this duty matters. If the buyer fails to withhold, or withholds but fails to pay the 3% into the AEAT, two consequences follow under the law. First, Article 25.2 of the IRNR Law provides that the transferred property remains encumbered (afecta) for the payment of the lesser of the withholding amount and the tax actually corresponding to the transferor. This means AEAT can pursue the property you just bought, not just the seller. Second, under the Ley General Tributaria (Ley 58/2003), the buyer is the withholding agent (retenedor), and a withholding agent who fails to deposit the retained amount is personally liable for the debt, plus late-payment surcharges and potential sanctions.

Article 42.1.c of the Ley General Tributaria extends solidarity responsibility to successors in the titularity or exercise of economic activities for obligations derived from the failure to deposit retentions. Article 79 (afeccion de bienes) makes the adquirente of goods affected by law to the payment of the tax debt subsidiarily liable. The practical effect is that a buyer who skips the filing cannot hide behind the seller’s absence. The encumbrance attaches to the property in the Land Registry, and a future sale by that buyer can be blocked until the debt is cleared. A buyer’s lawyer who overlooks the duty passes the liability directly to the purchaser.

When is the buyer exempt from withholding under Modelo 211?

The buyer is exempt from the Modelo 211 withholding in only two cases, both listed on the AEAT page for cases without the obligation. First, the seller proves they are a Spanish tax resident by producing a current certificate of tax residence (certificado de residencia fiscal) issued by the Agencia Tributaria, confirming they are subject to IRPF or corporate tax (Impuesto sobre Sociedades). Second, the property is contributed as capital in the incorporation or increase of capital of a Spanish resident company, a narrow corporate structuring case.

Without one of these two proofs, the buyer must withhold. The 3% applies regardless of whether the seller made a capital gain or a loss on the sale. The exemption is not about the seller’s profit, it is about the seller’s tax status. A non-resident seller who made a loss still triggers the buyer’s 3% duty, and the seller later reclaims the full retention via Modelo 210. Your lawyer should request the seller’s certificado de residencia fiscal before the deed. If the seller cannot produce it, the withholding is mandatory. No other exemption exists, not for a primary residence, not for a sale below the original purchase price, not for a transfer between family members. The AEAT page is explicit: the certificate of Spanish tax residence is the sole release.

How does the buyer’s Modelo 211 interact with the seller’s Modelo 210?

The two forms are a matched pair filed at opposite ends of the same transaction. The buyer’s Modelo 211 declares the 3% retention paid at source. The seller’s Modelo 210 declares the actual 19% IRNR capital gain and reconciles the retention. The buyer files first, within one month of the deed, and hands the seller the certificado de retencion. The seller files second, within four months of the deed (three months after the buyer’s one-month window closes), attaching the certificate as proof of the payment on account. The Agencia Tributaria cross-references the two filings. A buyer who files Modelo 211 correctly and on time enables the seller’s refund path. A buyer who does not file leaves the seller unable to evidence the retention, which in turn delays the seller’s reconciliation and can trigger AEAT to pursue the encumbered property.

The 19% flat rate applies to the seller’s taxable gain, calculated as the difference between the sale price and the documented acquisition cost. If the 3% retention exceeds the 19% IRNR due, the seller claims the excess back on the same Modelo 210 filing. The seller’s non-resident CGT guide walks through the seller’s side of this reconciliation in detail, and the Modelo 210 refund guide covers the refund mechanics the buyer’s filing unlocks.

How does a buyer calculate the 3% withholding on a real purchase?

The buyer calculates 3% of the agreed consideration (the price in the escritura publica). The AEAT Modelo 211 instructions specify that the “Transmission amount” (box 01) is the agreed consideration, and the retention (box 03) is that amount multiplied by 3%. If the property is owned by both resident and non-resident co-owners, the buyer withholds only on the proportion of the consideration corresponding to the non-resident owners’ shares. The AEAT instructions provide a worked example: a property sold for EUR 200,000 with 50% non-resident ownership means the buyer enters EUR 100,000 in box 01 and withholds EUR 3,000.

Purchase price	Non-resident share	3% retention the buyer pays	Seller receives at notary
EUR 300,000	100%	EUR 9,000	EUR 291,000
EUR 500,000	100%	EUR 15,000	EUR 485,000
EUR 1,000,000	100%	EUR 30,000	EUR 970,000
EUR 200,000	50% (one resident, one non-resident co-owner)	EUR 3,000	EUR 197,000 (proportional)

For a EUR 500,000 purchase from a non-resident seller on the Costa del Sol, the buyer pays the seller EUR 485,000 at the notary and deposits EUR 15,000 with AEAT via Modelo 211 within 30 days. The seller then files Modelo 210 within four months, declaring the 19% IRNR on the actual gain and deducting the EUR 15,000 the buyer already paid. If the seller’s IRNR liability is EUR 12,000 (because the gain was small), the seller claims the EUR 3,000 difference back. If the IRNR is EUR 25,000, the seller pays the extra EUR 10,000 on top of the retained amount. The buyer’s role ends with the Modelo 211 filing and the certificate handover.

How does the withholding fit into the wider non-resident tax cluster?

The buyer’s Modelo 211 duty sits inside a cluster of non-resident property tax obligations that interact on every purchase from a non-resident seller. The IRNR overview guide sets out the full non-resident income tax regime that the 3% retention feeds into. The Modelo 216 guide covers a parallel withholding duty on rental income paid to non-resident landlords, which a buyer who intends to let the property after purchase may encounter. The buying property as a foreigner guide places the withholding in the full acquisition process, and the selling property step-by-step guide covers the seller’s side of the same transaction.

The withholding is distinct from the transfer tax the buyer pays on the purchase itself. On a resale in Andalusia, the buyer pays ITP at a flat 7% to the Junta de Andalucia, a separate filing from the Modelo 211 retention. On a new build, the buyer pays 10% IVA plus approximately 1.2% AJD. The 3% Modelo 211 withholding is on top of those acquisition taxes, because it is a payment on account of the seller’s capital gains tax, not the buyer’s purchase tax. A buyer who conflates the two risks either overpaying at the notary or missing the Modelo 211 deadline entirely.

What practical steps should a buyer’s lawyer take at the notary?

A buyer’s lawyer should confirm the seller’s tax status before the deed date by requesting the certificado de residencia fiscal from the seller or their representative. If the seller is confirmed non-resident, the lawyer calculates 3% of the agreed consideration, arranges for the buyer to pay the seller 97% at the notary and hold the 3%, then files Modelo 211 electronically via the AEAT sede within the one-month window. The lawyer obtains the certificado de retencion and delivers it to the seller’s representative on or shortly after the deed date. The lawyer also records the cadastral reference of the property, which Modelo 211 requires, and the notary’s protocol number for the public document. A buyer who instructs a lawyer to handle the filing should still verify the Modelo 211 receipt and the certificate handover, because the legal liability for a missed deposit sits with the buyer as the withholding agent, not the lawyer.

This guide is general information, not legal or tax advice. Rules change and individual circumstances differ. Verify current requirements with an independent lawyer (abogado) or tax advisor (gestor/asesor fiscal) before acting. The 3% withholding and the one-month Modelo 211 deadline apply at the date of the public deed; confirm the filing window and the exemption conditions with your lawyer on the day.
