What is Modelo 210 in Spain and why must non-residents file it?

Form 210 is the official self-assessment form that non-residents use to declare and pay Spain’s Non-Resident Income Tax (IRNR) on property-related income. Whether your Spanish property sits empty or generates rental income, you are legally required to file this form every year with the Agencia Tributaria. 

This guide explains who must file, how the tax is calculated for both empty and rented properties, the current deadlines, the consequences of non-compliance, and why a fiscal representative can make the process straightforward. At Ábaco Advisers, our fiscal team has over 25 years of experience helping non-resident property owners stay compliant and avoid unnecessary penalties.

Many owners are genuinely surprised when they first learn about this obligation. A common reaction, especially among those who bought a holiday home and never rented it out , goes something like this: “Nobody told me I had to file a tax return every year just for owning an empty property.” Yet under Spanish law, this requirement applies to every non-resident property owner, regardless of whether the property generates any actual income. Understanding Form 210 directly affects your ability to sell your property smoothly, claim rightful refunds on the 3% retention, and avoid debts that could accumulate over years.

What is Form 210 and what is the IRNR?

Form 210 is the tax form issued by Spain’s Agencia Tributaria for the self-assessment of the IRNR (Impuesto sobre la Renta de No Residentes). It applies to individuals and legal entities that earn income in Spanish territory but have their tax residence outside Spain.

The IRNR is a state-level tax collected by the national tax authority, not your local town hall. Many non-resident owners already pay IBI (Impuesto sobre Bienes Inmuebles), which is a local council tax, and assume that covers all their obligations. It does not. The IRNR is a separate, additional obligation.

The legal basis is established in Real Decreto Legislativo 5/2004, de 5 de marzo, which approves the revised text of the Non-Resident Income Tax Act. Articles 24 and 25 set out how the tax base and rates are determined. Form 210 covers several income types, but for property owners the two most relevant are imputed income (empty properties) and rental income. For a broader overview, see our guide on non-resident taxes in Spain and our summary of all Spanish tax forms foreigners should know about.

Who must file Form 210 in Spain?

Any person or entity that is not a tax resident in Spain but owns property or earns income within Spanish territory must file Form 210. This applies to citizens from EU countries, the UK, and non-EU nations alike.

Under Spanish tax law, you are considered a non-resident if:

• You spend fewer than 183 days per calendar year in Spain.
• Your centre of economic interests is located outside Spanish territory.
• Your spouse and dependent children habitually reside outside Spain.

The requirement applies equally to all nationalities. For buyers from EU countries such as Poland or the Czech Republic, who increasingly see Spain as a stable place to invest. The good news is that EU residency qualifies them for the lower 19% tax rate. However, the filing obligation itself remains the same. Before filing, you will need a valid NIE number, which is Spain’s identification number for foreign nationals. If you are still considering a purchase, our guide to buying property in Spain covers the full process.

How is Form 210 calculated for an empty property (imputed income)?

If your property is not rented out, the tax authorities apply a deemed income, a notional figure calculated from your property’s cadastral value. The tax is typically modest, but it must be declared every year.

The valor catastral (cadastral value) can be found on your annual IBI bill. The percentage applied depends on when your municipality last revised its cadastral values:

• 1.1% if revised within the last 10 years.
• 2% if not revised within the last 10 years.

The resulting amount is taxed at 19% for EU/EEA residents or 24% for non-EU residents.

Practical example

If you own the property jointly, each co-owner must file separately for their ownership percentage. This calculation is established in Article 24.5 of the IRNR Act. For help determining the correct cadastral value, see our article on non-resident property tax.

How is Form 210 calculated for rental income?

If you rent out your property, you must declare the actual rental income received. The key difference between EU/EEA and non-EU residents lies in the ability to deduct expenses.

Deductible expenses for EU/EEA residents include:

• IBI and community fees proportional to the rental period.
• Repairs, maintenance, and cleaning costs.
• Mortgage interest (not capital repayments).
• Property management fees and insurance.
• Depreciation at 3% per year on the building value (excluding land).

For non-EU residents, tax has historically been calculated on gross income at 24% with no deductions. Recent court rulings are challenging this distinction, and changes are being implemented. Consult a qualified adviser for the latest position.

If your property is rented for only part of the year, you must declare rental income for the occupied months and imputed income for the vacant period. For more detail, see our article on tax on rental income in Spain.

What are the deadlines for filing Form 210?

The filing deadline depends on the type of income declared. Since 2024, a significant simplification has been introduced through Order HFP/1338/2023, allowing rental income to be grouped in a single annual filing instead of four quarterly submissions.

Deadlines at a glance

Filing is done electronically through the Agencia Tributaria’s portal. You will need a digital certificate, Cl@ve PIN, or an authorised representative. If you are selling property, the buyer’s lawyer withholds 3% via Form 211, you then use Form 210 to reconcile the final capital gains tax and claim any refund due.

What happens if you don’t file Form 210?

Non-compliance can result in surcharges, late-payment interest, and formal penalties. The consequences become more serious the longer the obligation remains unfulfilled.

If you file late but voluntarily, before the Tax Agency contacts you, the consequences are limited to surcharges:

• 1% if filed within the first month after the deadline, plus 1% for each additional full month.
• After 12 months, the surcharge rises to 15% and late-payment interest begins to accrue.

If the Tax Agency issues a formal notice, penalties can range from 50% to 150% of the unpaid tax. The Agencia Tributaria can inspect and claim unpaid taxes going back four years.

There is also a practical consequence. When you sell your property, any outstanding tax debts appear during the notary process. Unpaid obligations can delay or block the transfer of ownership. It is far easier to stay up to date than to resolve accumulated debts under pressure. See our guide on calculating capital gains tax for more on this.

Why should you appoint a fiscal representative for Form 210?

A fiscal representative handles the entire filing process, ensuring accuracy, applying the correct deductions, and meeting all deadlines. For non-residents unfamiliar with the Spanish tax system, this provides both practical support and peace of mind.

The representative also receives official notifications from the Tax Agency on your behalf, critical because the Agencia Tributaria communicates by post to your Spanish address, and non-residents frequently miss letters while abroad. Missing a notification can trigger automatic penalties. If you cannot be present in Spain, a power of attorney allows your representative to act on your behalf.

For EU property owners, a representative ensures that double taxation treaties between Spain and your home country are correctly applied.

Key takeaways

Form 210 is a legal obligation for every non-resident property owner in Spain. The tax is calculated differently for rental income versus imputed income, and rates vary based on your country of residence. Filing deadlines differ by income type, non-compliance brings surcharges and penalties, and appointing a fiscal representative simplifies the entire process. If you have questions about your situation, seeking professional guidance sooner rather than later is always the best approach.

Frequently asked questions about Form 210

Do I need to file Form 210 if my Spanish property is empty?

Yes. Spanish law requires all non-resident owners to declare imputed income based on the cadastral value, regardless of whether the property is rented, used personally, or left vacant.

What is the difference between Form 210 and IBI?

IBI is a local council tax paid to your town hall. Form 210 declares income tax owed to the national Agencia Tributaria under the IRNR. They are entirely separate obligations.

I have not filed for several years. What should I do?

File the missing declarations as soon as possible. Voluntary late filing carries only surcharges, not full penalties. The Tax Agency can go back up to four years.

Can I file Form 210 myself?

You can file through the Agencia Tributaria’s online portal using a digital certificate or Cl@ve PIN. However, most non-residents work with a fiscal representative to avoid errors and the language barrier.

Does the 3% retention when selling cover my Form 210 obligations?

No. The 3% retention (via Form 211) is a guarantee for capital gains tax only. Your annual IRNR obligations for imputed or rental income are separate and must be filed independently.
