Modelo 210 explained: what it is and the deadlines in 2026

Who has to file it

The Modelo 210 applies to anyone who is not tax-resident in Spain but earns Spanish-source income without a permanent establishment here. In practice, three situations account for almost every return:

• Owners of a property they do not rent out. Even though they receive nothing for it, the law attributes an imputed income calculated on the cadastral value of the property. This is the most common situation on the Costa Blanca and also the least understood.
• Owners who let the property. They declare the rental income received. Residents of the European Union, Iceland and Norway may deduct expenses connected to that income; everyone else is taxed on the gross amount.
• Anyone selling a property in Spain. They declare the capital gain and offset the 3% that the buyer has already paid over on their behalf.

Other situations exist — interest, dividends, business income without a permanent establishment — but for a foreign homeowner the three above cover almost everything. If yours is the first case, there is more detail in our answer on the Modelo 210.

Which tax rate applies

The IRNR distinguishes according to where you are tax-resident:

• 19% for residents of an EU member state, Iceland or Norway.
• 24% for residents of any other country.

The difference is not only the rate. Residents of the EU and the EEA can deduct from rental income the expenses directly linked to it (community fees, IBI, insurance, loan interest, depreciation, repairs), whereas someone resident outside that area is taxed on the gross rent. On a let with significant running costs, that distinction matters more than the headline rate.

In addition, the double taxation treaty Spain has with your country may change the outcome or let you offset in your own country what you pay here. To apply it you need a certificate of tax residence issued by the tax authority of your country of residence, specifically stated to be for treaty purposes.

The deadlines, case by case

Imputed income (property for your own use)

It accrues on 31 December each year and is declared during the following calendar year. So imputed income for the 2025 tax year is filed during 2026. If you choose to pay by direct debit from a Spanish account, the filing window closes earlier than the general one, around the end of December, so it is not something to leave until the last day.

Rental income

Rental income earned by non-residents is grouped into a single annual return filed within the first twenty calendar days of January of the following year. This changed from the earlier system, under which rentals were declared quarterly, so if you are following older guidance you may be working to a calendar that no longer exists.

Selling a property

Two separate returns and two separate deadlines come into play here:

1. The buyer withholds 3% of the agreed price and pays it over using form 211 within one month of the date of transfer, then gives you a copy of the receipt.
2. The non-resident seller files the Modelo 210 on the capital gain within the three months following the end of that first month — that is, within four months of the sale.

If the 3% withheld exceeds the tax actually due on the real gain — common where a property is sold with little profit or even at a loss — you can claim the difference back in that same return.

What happens if you do not file

The obligation does not disappear because you were unaware of it. The Agencia Tributaria has four years to claim each tax year, counted from the end of the voluntary filing period, and it routinely cross-checks Cadastre, Land Registry and utility data against the returns actually filed.

The financial difference between acting on your own initiative and waiting for a demand is substantial. Filing late but voluntarily triggers a surcharge that grows with the delay; receiving a formal demand first turns that surcharge into a penalty for a tax infringement, at a far higher amount. So if you have several unfiled years behind you, the sensible move is to regularise before selling: a sale brings the property's entire history to the surface.

What documents are needed

• NIE and passport or identity document of the owner (and of each co-owner, if the property is shared).
• Cadastral reference and the latest IBI receipt, which is where the cadastral value comes from.
• Ownership percentage and date of acquisition.
• Tenancy agreements and rental income for the year, with the related expenses, where applicable.
• Purchase and sale deeds, and the form 211 receipt, in the case of a transfer.
• Certificate of tax residence for treaty purposes, where you want to apply one.

The mistakes we see most often

• One return for a property with two owners. Each co-owner files their own return for their share of the property.
• Forgetting the period the property stood empty. If it is let for only part of the year, the rest of the year generates imputed income: both returns coexist.
• Applying 19% without being resident in the EU or the EEA. The rate depends on the owner's tax residence, not on nationality or on where the property is.
• Deducting expenses without being entitled to. Only residents of the EU, Iceland and Norway may do so, and only for expenses tied to the let period.
• Leaving imputed income until December. If the payment is direct debited, the window closes before the end of the year.

How we handle it

At Asistenio we calculate the amount for each tax year, file the return and send you the receipt, and if you wish we take on fiscal representation before the Agencia Tributaria so we receive the notifications and warn you of each deadline before it falls due. Everything is handled remotely: you do not need to travel to Spain.
