Modelo 210 in Spain: Attention all non-resident property owners

You bought a place in Spain. Maybe it was years ago: a two-bed apartment on the Costa Blanca, or a little finca you fell in love with on a holiday that turned into something bigger. You pay your IBI (local tax) bill every year, you keep your community fees up to date, and you think of yourself as a responsible property owner.

And then someone mentions the Modelo 210, and the whole room goes quiet.

If that sounds familiar, you are not alone – and if you want to sort it quickly and without fuss, IberianTax is an online platform thousands of non-resident owners across the world now use to do exactly that. But first, here is what you need to know.

What is the Modelo 210?

The Modelo 210 is the annual tax return Spain requires all non-residents who own properties or earn income in Spain to file every year. If you spend less than 183 days a year in Spain – which covers the vast majority of British holiday home owners – you are classified as a non-resident for tax purposes, and this obligation applies to you.

Here is the part that surprises most people: it applies even if your property earns absolutely nothing. You do not need to rent it out. You do not need to make a profit. Simply owning a property in Spain while living elsewhere is enough to trigger the Modelo 210 obligation. Spain treats the property as generating a notional or “potential” income – the idea being that you could rent it out if you wanted to – and taxes you on that basis. It is called imputed income, and it is compulsory.

There are three versions of the Modelo 210 regarding property tax, covering different circumstances:

• Imputed Income Tax – for properties not rented out, used for personal reasons or sitting vacant,
• Rental Income Tax – for properties that generate rental income through short or long-term rentals,
• Capital Gains Tax – when a property is sold

For most British holiday home owners, it is the first one – imputed income – that matters most, and that is what the rest of this article focuses on.

How much does it actually cost?

Less than most people fear, in most cases. The tax is calculated using your property’s cadastral value; that official administrative figure you will find on your IBI bill, at a rate of either 1.1% or 2%, depending on when the value was last revised. Tax is then applied at:

• 19% for EU and EEA residents,
• 24% for those outside of the EU/EEA, including UK nationals following Brexit.

For a property with a cadastral value of €80,000, the annual tax is likely somewhere between €170 and €380. It is not a life-changing sum. The problem comes when you ignore or postpone your Modelo 210 filing.

Leave it a year and you are looking at a surcharge of 1% per month. Leave it longer and that rises to 15% plus interest. And if the Spanish Tax Agency notifies you before you come forward yourself – which is increasingly likely in 2026, given how actively they are cross-referencing property data – the penalty starts at 50% of whatever was owed.

Key deadlines for non-resident property owners

• Imputed Income: File for the 2025 tax year by 31 December, 2026.
• Rental Income: Declare 2026 rental income between 1 and 20 January 2027.
• Capital Gains: Submit within four months of your property’s official sale date.

The imputed income window is open right now and has been since January 2026, which means there is nothing stopping you from getting it done today. Filing early is simply the sensible option: it keeps you fully compliant, removes the risk of a rushed or incorrect declaration, and it takes it off your yearly to-do list.

Filing it yourself: Possible, but not easy

The Modelo 210 can be filed directly through Spain’s government portal, but for most non-residents it is a frustrating experience. The site is in Spanish, online filing requires a digital certificate that is difficult to obtain from abroad, and the tax calculation is entirely down to you. A single error – with the tax calculation, in the wrong field, or with the wrong reference – and the submission is rejected. The system works well for Spanish tax professionals. For everyone else, it is a steep learning curve.

A simpler way to get it done

This is where IberianTax comes in – and it is worth knowing about whether you use them or not, simply because understanding the options makes the whole thing less daunting.

IberianTax is a digital solution, an officially recognised AEAT collaborator, which means it files Modelo 210 returns directly with Spain’s Tax Agency on behalf of clients. The online platform is fully in English, and their accurate software calculates the tax for you. No digital certificate, no Spanish bank account, no prior knowledge required. Just your NIE, your cadastral value from your IBI bill, and a payment method.

Most people complete the process in under 5 minutes, praising how easy and simple the whole process is, and receive an official AEAT receipt in their account within a couple of days.

The cost is just €34.95 per filing (including VAT) – a fraction of the €150-€300 a traditional gestor or lawyer charges, without the language barrier or the long waiting times.

For those who never want to think about this again, IberianTax also offers an Automatic Filing option: choose your filing date, and the Modelo 210 is submitted on your behalf every year without you lifting a finger – with a reminder 30 days before in case anything needs adjusting. Over 1,000 people are already using this tool, at no extra cost.

What if you’ve never filed?

You are not alone – and the situation is recoverable. The Spanish Tax Agency can look back up to four years, so it is worth getting older filings sorted sooner rather than later. Filing voluntarily, before receiving any communication from the Spanish Tax authorities, keeps surcharges at a low. Waiting until they contact you does not.

If that feels overwhelming, it is worth knowing that IberianTax handles back-filings for previous years in exactly the same way as current ones – it is one of their most common requests.

Frequently asked questions

Do I really have to file if my property just sits empty? Yes, this is the one that catches most people out. An empty property, a holiday-only property, a property used purely by family, all of these still require an annual Modelo 210 filing for imputed income.

Does Brexit change things for British owners? It does, slightly. UK nationals are now taxed at 24% rather than the 19% rate that applies to EU residents. The obligation itself has not changed – just the rate UK nationals are now taxed on.

What if I’ve missed previous years? File as soon as you can. The sooner you do it voluntarily, the lower the surcharge will be. The AEAT is more active in 2026 than it has been in previous years when it comes to identifying non-filers and tracking non-resident activity.

The 2025 imputed income deadline is 31 December 2026 – which means the window is open and there is no reason to wait.
