The Modelo 210 Tax Refund in Spain: How Non-Resident Owners Claim Back Overpaid Tax

A non-resident property owner who overpaid Spanish tax can claim the excess back through the Modelo 210 refund path (devolucion). The most common scenario is the 3% buyer retention on a property sale exceeding the actual IRNR capital gains liability, but the same mechanism covers unclaimed deductible expenses on rental income and imputed income paid on a property that was in fact rented. The right to request the refund prescribes after four years under Article 66(c) of the Ley 58/2003 General Tributaria, and the Agencia Tributaria pays interest on late payment automatically if it misses the six-month payment window.

What is a Modelo 210 tax refund and when does it arise?

A Modelo 210 tax refund (devolucion) is the procedure by which a non-resident taxpayer reclaims tax paid or retained in excess of the IRNR actually due. The Agencia Tributaria defines the refund procedure as covering “cantidades ingresadas o soportadas debidamente como consecuencia de la aplicacion del tributo”, and the Modelo 210 instructions expressly allow the form “para solicitar la devolucion de un exceso de retencion o ingreso a cuenta en relacion con la cuota del impuesto”. Three refund scenarios dominate for non-resident property owners.

First, the 3% buyer retention on a property sale. When a non-resident sells Spanish property, the buyer is legally required to retain 3% of the sale price and pay it to the Agencia Tributaria, per Article 25.2 of the consolidated IRNR text (Real Decreto Legislativo 5/2004). The 3% is an advance against the seller’s 19% IRNR capital gains liability, not a separate tax. If the actual gain is lower than the retention implies, the seller claims the excess back via Modelo 210.

Second, deductible expenses on rental income that were not claimed when the original Modelo 210 was filed. EU and EEA residents can deduct IRPF-equivalent expenses against rental income under Article 24.6 of the IRNR, and a supplementary autoliquidacion can recover overpaid tax within the prescription window.

Third, imputed income tax paid on a property that was rented out for part or all of the year. If a non-resident paid the 1.1% or 2% imputed income on a property that was actually tenanted, the rental income should have been declared instead at 19% (EU/EEA) or 24% (non-EU), and the difference can be reclaimed.

Refund scenario	What was overpaid	How the refund arises	Filing route
3% retention exceeds actual IRNR gain	3% of sale price retained by buyer	Actual gain lower than retention implies, or zero gain	Modelo 210 (transmisiones)
Unclaimed rental deductions	IRNR at 19% or 24% on gross rental	Deductible expenses not claimed on original filing	Modelo 210 (complementaria)
Imputed income on a rented property	Imputed income tax (1.1% or 2%)	Property was rented, should have been declared as rental income	Modelo 210 (rectificativa)

How does the 3% retention refund path work on a property sale?

The retention refund path is a matched pair of filings. The buyer’s Modelo 211 declares the 3% retention and is filed within one month of the public deed. The seller’s Modelo 210 declares the actual IRNR capital gain and is filed within three months after that one-month window, per the Agencia Tributaria manual on non-resident taxation. The 3% retention the buyer paid is deducted from the IRNR due, and if the retention exceeds the final liability, the seller claims the excess back in the same Modelo 210 filing.

The Agencia Tributaria confirms this route on its retenciones page: “Cuando un no residente haya soportado una retencion superior a la tributacion que le corresponda, podra solicitar la devolucion del exceso retenido a traves del modelo 210”. The seller attaches the Modelo 211 retention receipt that the buyer delivered at the notary, the escritura de compraventa, documented acquisition costs (ITP, notary, registry, legal and valuation fees), and the NIE plus non-resident certificate.

A worked example clarifies the arithmetic. A non-resident sells a Costa del Sol apartment for EUR 600,000, bought for EUR 500,000 with EUR 42,000 in documented acquisition costs (ITP at 7%, notary, registry, legal), giving a base of EUR 542,000. The taxable gain is EUR 58,000. The IRNR at 19% is EUR 11,020. The buyer retained 3% of EUR 600,000, which is EUR 18,000. The retention exceeds the IRNR by EUR 6,980, and the seller claims that EUR 6,980 back in the Modelo 210 filing. The non-resident CGT guide sets out the full sale-side tax stack, and the non-resident rental income tax guide explains the rental-side filing that a deduction refund amends.

What is the four-year prescription window for a Modelo 210 refund?

The right to request a tax refund in Spain prescribes after four years. Article 66 of the Ley 58/2003 General Tributaria lists four rights that prescribe at four years, and two of them concern refunds: Article 66(c) the right to request devoluciones derivadas de la normativa de cada tributo, and Article 66(d) the right to obtain them. The prescription is applied oficio (automatically) under Article 69.2, even if the taxpayer has already paid, and it extinguishes the debt under Article 69.3.

The computation rule is in Article 67. For the right to request a refund (66(c)), the clock starts the day after the deadline for filing the original return, or where there is no deadline, the day after the refund could first have been requested. For the 3% retention refund, the four years run from the day after the Modelo 210 filing deadline for that property sale. The Agencia Tributaria manual confirms that refund autoliquidaciones “podran presentarse a partir del 1 de febrero del ano siguiente al de devengo de las rentas declaradas y dentro del plazo de cuatro anos contados desde el termino del periodo de declaracion e ingreso de la retencion”.

The interruption rule is in Article 68. For the right to request a refund (66(c)), any formal act by the taxpayer toward the refund, such as filing the autoliquidacion or filing an administrative appeal, resets the full four-year clock. The tax prescription guide explains the full prescription framework across property taxes.

Refund right	Prescription period	Clock starts	Interruption event
Request a refund (Art 66(c))	4 years	Day after original return deadline	Any formal taxpayer act toward refund (Art 68.3)
Obtain a refund (Art 66(d))	4 years	Day after the deadline for the AEAT to pay	Any AEAT action toward payment, or taxpayer demand (Art 68.4)

How does the AEAT refund procedure work and when does interest accrue?

The refund procedure is initiated by filing a Modelo 210 autoliquidacion with a result to return (devolver). The Agencia Tributaria examines the documentation and contrasts it with data it holds. If the procedure is clean, the refund is paid by bank transfer to the account the claimant designates, and the transfer itself serves as notification of the agreement. The AEAT allows payment to a foreign bank account, either SEPA or non-SEPA, and the claimant provides the IBAN and BIC or SWIFT at filing.

The critical six-month rule is set out on the G222 procedure page. If six months pass without the refund being ordered for reasons attributable to the administration, the AEAT pays interes de demora (interest on late payment) automatically, without the claimant needing to request it, from the end of that six-month period until the date the payment is ordered. The interest rate for 2026 is 4.0625 per cent per annum, derived from the legal interest of the money (3.25% for 2026, maintained by budget prorogation) plus 25 per cent, per Article 26.6 of the General Tributaria. The fiscal representative guide explains why appointing one speeds the refund: the AEAT routes correspondence through the representative, and a representative-filed claim typically lands in four to 12 months versus 12 to 18 without one.

The procedure can also end in caducidad (if the taxpayer paralyzes it for three months), in a verification or inspection procedure, or in a partial retention (medida cautelar) where the AEAT holds part of the refund pending further checks. The taxpayer can appeal via reposicion (one month, potestative) or via a reclamacion economico-administrativa (one month).

What changed with the Orden HAC/623/2026 for Modelo 210 filing deadlines?

The Orden HAC/623/2026, de 12 de junio (BOE 23 junio), modifies the Modelo 210 form content and filing deadlines for imputed income and rental income, effective for autoliquidaciones presented from 1 January 2027. For imputed income of urban properties, the filing window moves from 1 January to 31 December of the following year, to 1 April to 31 December. For rental income with a result to pay, grouped filing moves to the first 20 days of April of the following year, and the grouping period is now annual (not quarterly) for devengos from 2024. The AEAT confirms that these changes do not affect the 3% retention refund path for property sales, which keeps its three-month-after-one-month window. The rental tax deductions guide covers the deductible expense categories that a refund claim on rental income relies on, and the IRNR regime guide sets out the full non-resident income tax framework.

The key practical point for a refund claimant is that the new deadlines apply to the original filing, not to the refund request itself. The four-year prescription window for a refund runs from the deadline of the original return, so a 2026 rental income return filed under the new April 2027 deadline starts its four-year refund clock from the day after 20 April 2027, not from the old January deadline.

What documentation does a Modelo 210 refund claim require?

The documentation depends on the refund scenario. For a 3% retention refund on a property sale, the claimant files the Modelo 210 autoliquidacion with the result to return, and attaches the escritura publica de compraventa, the Modelo 211 retention receipt the buyer delivered at the notary, documented acquisition costs (ITP receipt, notary invoice, Land Registry invoice, legal fee invoice, valuation invoice), the NIE, and a non-resident certificate. Where a double-taxation convention is applied, a certificate of fiscal residence from the home country’s tax authority is required, valid for one year from issue.

For a rental deduction refund, the claimant files a complementary Modelo 210 and attaches the certificates of retention (if the tenant withheld), the expense receipts (community fees, IBI, insurance, property tax, management fees, repairs), and the rental contract. The non-resident rental income guide lists the deductible expense categories in full.

For an imputed-income-on-a-rented-property refund, the claimant files a rectificativa Modelo 210 substituting the rental income declaration for the imputed income declaration, and attaches the rental contract and proof of rental income for the period.

Refund type	Form	Key attachments	Filing window
3% retention refund (sale)	Modelo 210 (transmisiones)	Escritura, Modelo 211 receipt, acquisition costs, NIE	3 months after buyer’s 1-month window
Rental deduction refund	Modelo 210 (complementaria)	Expense receipts, rental contract, retention certificates	4 years from original return deadline
Imputed income rectification	Modelo 210 (rectificativa)	Rental contract, rental income proof	4 years from original return deadline

How does a non-resident actually file the Modelo 210 refund?

The filing is electronic, through the Agencia Tributaria Sede Electronica. The claimant accesses the Modelo 210 presentation page, selects the autoliquidacion with result to return (devolver), completes the form, and attaches the documentation. Identification is via electronic DNI, digital certificate, or Clave PIN. A fiscal representative can file on the claimant’s behalf using their own digital certificate, which is the standard route for non-EU residents who must appoint one.

The refund can be paid to a Spanish bank account or a foreign account. For a SEPA account, the claimant provides the IBAN. For a non-SEPA account, the claimant provides the IBAN and BIC or SWIFT, and the transfer is in euros. The AEAT Modelo 210 filing page confirms that “Puede solicitar la devolucion en una cuenta extranjera, ya sea de paises de zona SEPA o resto de paises”. The claimant should verify the IBAN carefully, as an incorrect IBAN is the most common cause of a delayed refund.

A non-EU or non-EEA resident must appoint a Spanish tax representative before filing, who accepts joint liability for the IRNR declaration. An EU or EEA resident can file without one, but the refund typically takes longer and the AEAT correspondence route is less reliable without a representative. The representative fee, typically EUR 200 to EUR 600 per sale, is a documented deduction on the IRNR calculation.
