The Modelo 210 filing deadline isn’t a single date — it changes depending on the type of income you’re declaring, and mixing one deadline up with another is the most costly mistake a foreign property owner in Spain can make.
If you own a home here and you’re not a Spanish tax resident, you’ll eventually run into this form, and knowing exactly when to file it avoids surcharges that, over time, can reach 15% of the amount owed.
Modelo 210 is the document Spain’s tax authority uses to manage the Non-Resident Income Tax (IRNR). It covers three very different situations: the income Spanish tax law “imputes” to you for owning an empty property, rental income if the property is let out, and capital gains if you decide to sell. Each one runs on its own calendar, and the regulation (Order EHA/3316/2010) sets them out separately.
In this guide by Sol-4 Gestión, we walk you through the exact deadline for each situation, using up-to-date data from Spain’s Tax Agency, how the Modelo 210 pre-declaration works if you want to set up direct debit, and what happens if the deadline slips past you without you realising.
What Is Modelo 210 and Who Needs to File It?
Modelo 210 is the single form used by property owners and taxpayers who are non-tax-residents in Spain to declare any income obtained on Spanish soil. You’re considered a non-resident if you spend fewer than 183 days a year in Spain, regardless of your nationality.
Unlike Modelo 100 (for residents), Modelo 210 allows you to declare income separately or grouped together, depending on the type. In short, IRNR is the tax that replaces personal income tax when the property owner isn’t taxed as a Spanish resident.
You need to file it if:
- You own an empty property in Spain (imputed income).
- You rent that property out, even occasionally.
- You sold a property and made a capital gain.
- You received dividends, interest, or other Spanish-sourced income without the correct withholding applied.
Modelo 210 Filing Deadline by Type of Income
This is where most owners get confused: there is no single Modelo 210 deadline, but a different one for each type of income. Since 2024, the old quarterly system for rental income has also disappeared in favour of a single annual filing.
| Type of income | Filing deadline |
| Imputed income (empty property, 2025 tax year) | The entire following calendar year: until 31 December 2026 (23 December if you set up direct debit) |
| Imputed income (from the 2026 tax year onward) | 1 April to 31 December of the following year |
| Rental income (annual grouping) | 1 to 20 January of the year following the income |
| Capital gains (property sale) | Three months once the month following the date of transfer has elapsed (roughly 4 months from the sale) |
| Other income (dividends, interest, employment income) | The first 20 calendar days of April, July, October and January |
One important nuance: if you sold your property partway through the year, you still owe the imputed income declaration for the months you owned it. This is one of the most common oversights among sellers — two separate filings are required, not one.
Modelo 210 Tax Agency Filing: How It Works and What the Pre-Declaration Is
All self-assessments are filed directly through the Tax Agency’s electronic office, using a digital certificate, Cl@ve, or, in some cases, through a representative. The system generates a pre-declaration, a draft you can review before confirming the final submission — particularly useful if it’s your first time filing.
Filing online also lets you set up direct debit if you file within certain cut-off dates: by 23 December for imputed income, or by the 15th of the relevant month for other income types. Outside those dates, the filing is still valid, but payment has to be made through other means.
If you sold a property, it’s also worth understanding Modelo 211: it’s the form the buyer uses to pay a 3% withholding on the sale price directly to the tax authority, as an advance payment against your capital gains declaration on Modelo 210 itself. In our guide to buying property in Spain as a foreigner, we explain how this withholding works from the buyer’s side.
What Happens If You Miss the Modelo 210 Deadline
Missing the Modelo 210 deadline isn’t just an administrative slip — it triggers automatic surcharges, and they grow the longer it takes you to correct it.
- If you file voluntarily after the deadline, before any notice from the tax authority: a 1% surcharge per month of delay, up to a maximum of 15% after twelve months.
- If the tax authority notifies you first: the penalty rises to between 50% and 100% of the amount owed, plus late-payment interest.
- In the most serious or repeated cases, the matter can escalate to criminal proceedings.
The good news is that these consequences are almost always avoidable with a simple deadline calendar — and, if you own property across different regions or income types, with advice that keeps that calendar for you.
Common Mistakes Non-Residents Make With Modelo 210 Deadlines
Even well-organised owners tend to trip up on the same issues, year after year:
- Assuming an empty property isn’t taxed. Imputed income applies whether you use the property or not.
- Still filing rental income quarterly. Since 2024, rental income is declared annually, not quarterly.
- Forgetting imputed income after selling. If you sold mid-year, you still owe the proportional share for that year.
- Missing the direct debit cut-off by filing at the very last moment, with no room for errors on the form.
- Filing a single Modelo 210 for several properties. Each cadastral reference — house, garage or storage unit — needs its own declaration.
Most of these mistakes don’t come from carelessness — they come from managing the Spanish tax calendar without support from outside the country. Our tax and accounting service exists for exactly this reason: we work out what each property owes, file within the deadline, and make sure none of these five slip-ups turns into a surcharge.
Before the Deadline Becomes a Problem, Put It in the Hands of Someone Who Tracks It Every Year
Managing Modelo 210 from outside Spain, without a working knowledge of the Spanish tax calendar, is where most foreign owners make mistakes that end up costing money.
At Sol-4 Gestión, we handle full fiscal representation for our non-resident clients on the Costa Blanca: we calculate your imputed income or rental income, file within the deadline, and flag every cut-off date in advance, so you don’t have to keep track of the Spanish Tax Agency’s calendar from abroad.
If you’re also planning to sell your property, or you’ve already arranged your non-resident mortgage, we coordinate the Modelo 211 withholding and the final capital gains calculation as well.
Frequently Asked Questions About the Modelo 210 Deadline
It depends on the type of income: imputed income is filed throughout the following calendar year (until 31 December), rental income between 1 and 20 January, and capital gains within roughly 4 months of the sale.
It’s the income the Spanish tax authority assumes a second home generates simply by belonging to you, even if it sits empty. It’s calculated on the cadastral value and declared every year through Modelo 210.
No. Since the 2024 tax year, rental income is grouped into a single annual filing, between 1 and 20 January of the following year.
You need to file two declarations: the capital gain from the sale (within roughly 4 months) and the proportional imputed income for the days you owned the property that year.
Modelo 211 is filed by the buyer to pay a 3% withholding on the sale price. You, as the seller, then use Modelo 210 to settle your actual capital gain, deducting that withholding.
Yes, if you file before certain dates: 23 December for imputed income, or the 15th of the relevant month for other income types. Outside those dates, online filing is still valid, but the payment can’t be direct-debited.
An automatic 1% surcharge applies per month of delay if you file voluntarily, up to 15% after a year. If the tax authority notifies you first, the penalty rises to 50-100% of the amount owed, plus interest.
It’s the most common way to file it online directly through the Tax Agency’s electronic office, although you can also do it through a fiscal representative who files on your behalf.
