Modelo 210 for Married Couples and Joint Owners: Why One Spanish Property Can Mean Four Tax Returns

If you own Spanish property jointly as non-residents, Spain does not normally treat you as one family taxpayer. Each co-owner files their own Modelo 210 for their share. And if your garage or storage room has its own cadastral reference, that can mean another return for each owner. One couple, one apartment, one separate garage: four returns.

Key facts

So, this is one of those small Spanish tax traps nobody mentions at the notary.

You buy a holiday apartment on the Costa Blanca. You are married. The escritura says you own it together, 50/50. There is a garage space included. Nothing is rented, nothing dramatic is happening, you just use the property for holidays and family visits.

Then the annual non-resident tax comes around and you assume, very reasonably, that there is one property, one couple, one return.

Well, no.

For Modelo 210 imputed income, Spain looks at each non-resident owner separately. Your spouse is not folded into your return. Your ownership share is not merged into one family filing. And if the garage has its own cadastral reference, the tax office treats that as another property for this purpose.

That is how one normal married couple can end up with four small Modelo 210 returns every year.

Not four large taxes, usually. Four returns.

And that difference matters.

The rule nobody explains: each co-owner is a separate taxpayer

For non-resident income tax, each owner of the Spanish property is their own taxpayer.

If you own 50 percent, you declare 50 percent. If your spouse owns the other 50 percent, they declare the other 50 percent. You do not file a joint annual Modelo 210 for imputed income just because you are married.

This is the point that catches people.

They search "modelo 210 married couple" and find pages talking about non-resident tax in general. Or they receive a short reminder from someone saying "file your Modelo 210", singular. Or they paid it once years ago and nobody checked whether the filing matched the actual ownership.

But the Spanish logic is very plain once you see it. The taxpayer is the individual owner, not the couple.

So if a British couple owns a property 50/50, there are two imputed income returns for the apartment. One for the husband. One for the wife. Same property, same cadastral value, same year, but two taxpayers.

Okay, but what about joint owners who are not married?

Same idea. Brothers and sisters, unmarried partners, friends buying together, parents and adult children. Each co-owner declares their own percentage of the imputed income.

There is no magic in the marriage certificate for annual imputed income.

The garage problem: same deed, different cadastral reference

Now, the second trap.

Many properties on the Costa Blanca come with a garage space or storage room. Sometimes it feels like part of the apartment. Sometimes it is written in the same deed. Sometimes the owner has never thought about it as a separate property.

But for Modelo 210 imputed income, the practical question is not "was it bought together?"

The question is: does it have its own cadastral reference?

If the garage or storage room has its own cadastral reference, it generates its own imputed income. And because imputed income from different properties cannot be grouped into one return, that separate cadastral reference means a separate Modelo 210.

So, apartment plus garage can become two properties for Modelo 210.

And when there are two owners, that becomes:

Four returns.

This is why "modelo 210 garage separate return" is not a technical curiosity. It is a real annual filing issue for many non-resident owners.

Honestly, the amounts are often small. That is the reassuring part. The problem is not usually the tax bill. The problem is filing one return when the structure of the ownership and cadastral references actually creates four.

The one joint Modelo 210 exception

There is one exception people half remember, and it creates confusion.

When a non-resident married couple sells a jointly owned Spanish property, they may file a single Modelo 210 for the sale.

That is the sale case.

It does not apply to annual imputed income for own-use property.

So if you are asking about the yearly Modelo 210 for a holiday home that is not rented, do not import the sale rule into the annual filing. For imputed income, each spouse files their own return.

Short version: joint return possible for a sale by a married non-resident couple. Not for annual imputed income.

How imputed income is calculated

Now, the tax itself.

If the Spanish property is for your own use and not rented, Spain still taxes a notional income. In English we usually call this imputed income. It is not rental income you actually received. It is a legal calculation based on the cadastral value.

The percentage is:

Then the tax rate depends on where you are tax resident.

For residents of the EU, Norway and Iceland, the rate is 19%.

For everyone else, the rate is 24%. And yes, that includes the UK since Brexit.

That last line is still where many British owners pause. But for this purpose, the UK is on the 24 percent side.

Worked example: UK couple, apartment plus garage

Let us make it concrete.

A UK couple owns a Costa Blanca apartment 50/50, plus a garage with its own cadastral reference, also 50/50. Nothing is rented. Both properties are for their own use.

The apartment cadastral value is 80,000 euros. It has been revised, so 1.1% applies.

80,000 x 1.1% = 880 euros imputed income

Each spouse declares half.

880 / 2 = 440 euros each

The UK is treated as a third country for this rate, so 24% applies.

440 x 24% = 105.60 euros each

Now the garage.

The garage cadastral value is 6,000 euros. It has also been revised, so 1.1% applies.

6,000 x 1.1% = 66 euros imputed income

Each spouse declares half.

66 / 2 = 33 euros each

Tax at 24%.

33 x 24% = 7.92 euros each

So the couple files four returns:

So, not a terrifying amount.

But four returns, not one.

Now compare the same facts for an EU couple, say Germany. Same cadastral values, same 50/50 ownership, same separate garage. The difference is the rate: 19% instead of 24%.

440 x 19% = 83.60 euros each for the apartment
33 x 19% = 6.27 euros each for the garage

Across the same four returns, the total is 179.74 euros.

Same properties. Same number of returns. Different tax rate.

When do you file now?

This is another point where old habits can mislead you.

For imputed income accrued from 2026 onwards, the filing window is from 1 April to 31 December of the following year.

So the 2026 imputed income is filed between 1 April and 31 December 2027.

For income accrued up to 2025, the old rule applies: the whole following calendar year.

That means there is a transition in the calendar. If you have an old mental note saying "I can file any time during the following year", be careful. That is true for income accrued up to 2025. From 2026 onwards, the window starts on 1 April.

Okay, but what does that mean in normal language?

It means you should not wait until December assuming everything is still as flexible as before. The deadline remains 31 December for imputed income, but the opening date changes for 2026 onwards. If you are organising several returns for a couple, especially with a garage or storage room, it is better to know the count early.

Why this catches careful owners

The strange thing is that the people caught by this are often not careless.

They bought properly. They have their NIE numbers. They pay IBI. They may even have filed Modelo 210 before.

The problem is that the structure is hidden in plain sight. You think in life terms: "our apartment", "our garage", "our holiday home". The tax form thinks in taxpayer shares and cadastral references.

And those are not the same map.

A couple sees one home. The tax office may see two taxpayers and two cadastral references. That is four filing positions.

So when someone says "I filed the Modelo 210 for the property", the first question should be: for which owner, and for which cadastral reference?

Not because anyone is trying to be difficult. Because that is how the annual non-resident imputed income filing works.

A practical way to check your position

Start with three questions.

First, who owns the property and in what percentages?

If it is 50/50, each owner normally declares half. If it is 70/30, one owner declares 70 percent and the other declares 30 percent. Do not average it. Do not invent a family split. Follow the ownership.

Second, how many cadastral references are involved?

The apartment may have one. The garage may have another. A storage room may have another. If a garage or storage room has its own cadastral reference, it is not just a footnote for this purpose.

Third, where are the owners tax resident?

EU, Norway and Iceland means 19 percent. Everyone else means 24 percent. The UK is on the 24 percent side since Brexit.

Once you know those three things, the return count is usually mechanical.

You can run the numbers through the Easy210 calculator to see the likely imputed income and tax per owner, or book a consultation if your property has several owners, several cadastral references, or a history of missed filings. The point is not to make this bigger than it is. The point is to count it correctly.
