25 Questions Foreign Property Owners Ask About Spanish Tax

Owning a property in Spain while living abroad creates a surprisingly wide range of tax questions.

Some are straightforward. Others only become apparent after you start renting the property, receive a letter from the Spanish Tax Agency, inherit a property, or decide to sell.

At IberianTax, we specialise in Spanish taxation for non-resident property owners. In this guide, we answer 25 of the questions that matter most — including several that owners often do not think to ask until they become a problem.

This article focuses primarily on individuals who are tax resident outside Spain and own residential property in Spain.

Owning a property in Spain

Do I really have to pay Spanish tax if I never rent out my property?

In most cases, yes.

Spain applies what is known as imputed income tax to non-residents who own urban property that is available for their own use.

This means that even if your Spanish property is only a holiday home, remains empty for most of the year or produces no actual income, you may still have to file a Modelo 210.

The taxable amount is calculated using the property's cadastral value rather than any income you have actually received.

I already pay IBI every year. Doesn't that cover my Spanish property tax?

No. This is probably one of the most common misunderstandings among foreign property owners.

IBI is a local property tax charged by the municipality.

Modelo 210, on the other hand, is a national tax return used to declare Non-Resident Income Tax.

Paying your annual IBI bill therefore does not replace your obligation to file Modelo 210 where one is required.

It is perfectly normal for a non-resident owner to have to pay both taxes each year.

If I spend fewer than 183 days in Spain, am I automatically a non-resident?

Not necessarily.

Spending more than 183 days in Spain during a calendar year is one of the main tests for Spanish tax residence, but it is not the only one.

You may also be considered Spanish tax resident if Spain is the main centre or base of your economic activities or interests. There is also a rebuttable presumption connected with a spouse and dependent minor children habitually living in Spain.

Double Taxation Treaties may then determine residence where two countries consider someone resident.

So the often-repeated rule that “under 183 days automatically means non-resident” is an oversimplification.

My property is jointly owned. Can we submit one Modelo 210 for the property?

Generally, no.

For Non-Resident Income Tax purposes, each owner is a separate taxpayer.

If two people own a property 50/50, each normally declares their respective 50% share. The same applies where a property belongs to spouses, siblings, friends or several heirs.

The Spanish Tax Agency attributes income to each owner according to their ownership percentage.

This is why the number of tax returns can sometimes be considerably higher than the number of properties.

Do my garage and storage room also need to be declared?

Potentially, yes.

A garage, storage room or other property element that is legally and cadastrally independent can be treated as a separate property for tax purposes.

A particularly important warning sign is a separate cadastral reference.

Foreign owners frequently assume that everything purchased together with their apartment forms part of a single tax return, when this is not always the case.

This is one of the reasons we recommend checking the escritura, Land Registry information and IBI documentation rather than relying only on the postal address.

What happens if I bought or sold the property during the year?

You do not normally pay imputed income tax as though you had owned the property for the full year.

The calculation is made proportionally according to the number of days during which the property was owned and available to you.

For example, someone who buys a holiday home on 1 July will generally only calculate imputed income for the relevant part of that year.

The same principle is relevant in the year in which a property is sold.

What if friends or family stay in my property for free?

Allowing relatives or friends to use the property without paying rent does not normally create rental income.

However, that does not necessarily eliminate the imputed income tax obligation.

For a typical non-resident holiday-home owner, days on which the property is not genuinely rented will generally remain within the personal-use/imputed-income calculation.

Owners should therefore not simply classify free occupation by family or friends as rental days.

Renting out your Spanish property

What happens if I rent the property for only part of the year?

This is one of the most important situations to get right.

The year must normally be divided into two periods:

• the days during which the property was rented, which generate rental income; and
• the remaining days during which the property was available for personal use, which may generate imputed income.

So renting your property for three months does not normally eliminate your Modelo 210 obligation for the other nine months.

Do I have to declare Airbnb or Booking.com income?

Yes.

Using Airbnb, Booking.com or another platform does not remove the obligation to declare Spanish rental income.

The tax treatment depends on the nature of the rental and the services provided, but the fact that a platform collects the money on your behalf does not make that income tax-free.

Owners of holiday rentals should also remember that tax obligations are separate from tourism-registration, licensing and other regional or local requirements.

Is my Spanish rental tax rate based on my nationality?

No. What generally matters is your tax residence, not your passport.

Under the current IRNR rules:

• residents of EU countries, Iceland, Norway and Liechtenstein generally face a 19% rate;
• most other non-residents are subject to 24%.

The distinction is also important because eligible EU/EEA residents may deduct qualifying rental expenses.

For example, a British citizen who is tax resident in France may have a different Spanish tax position from a British citizen who is tax resident in the UK.

If Spain taxes my rental income, will I also have to pay tax on it in my home country?

Potentially, but that does not necessarily mean paying the full tax twice.

Income from Spanish real estate is generally taxable in Spain because the property is situated here. Your country of tax residence may also require you to report foreign rental income.

Double Taxation Treaties normally contain mechanisms intended to prevent the same income being fully taxed twice, frequently through a foreign-tax credit.

The precise result depends on the treaty between Spain and your country of residence and on that country's domestic rules.

This is why Spanish tax and home-country tax should not be considered entirely in isolation.

Which rental expenses can EU/EEA residents deduct?

Eligible EU/EEA residents can generally deduct expenses that are directly connected with obtaining the Spanish rental income.

Depending on the circumstances, these may include items such as:

• IBI and certain local taxes;
• community fees;
• insurance;
• utilities paid by the owner;
• property-management and agency fees;
• repairs and maintenance;
• financing costs;
• depreciation.

Expenses must be properly supported and the rules on proportionality must be respected where the property was only rented for part of the year.

Can UK, US and other non-EU owners deduct rental expenses?

Under the Spanish Tax Agency's current administrative position, residents outside the EU/EEA generally cannot deduct these expenses and are taxed at 24% on gross rental income.

However, this is currently one of the most important areas of Spanish non-resident taxation.

In July 2025, the Spanish National Court ruled that restricting these deductions for non-EU residents was contrary to EU law. That decision has been appealed and the issue remains pending before the Supreme Court.

For affected owners, keeping complete records of rental expenses is therefore particularly important, even where those expenses cannot currently be included in the ordinary return.

Can I deduct my mortgage payments?

Not the full mortgage payment.

There is an important distinction between capital repayments and interest/financing costs.

Repaying the amount originally borrowed is not normally a rental expense.

Interest and certain financing costs connected with the acquisition or improvement of the rented property may, however, be deductible for taxpayers who qualify to deduct expenses, subject to the applicable limits and rental-period rules.

Simply taking the monthly mortgage payment and treating the whole amount as an expense would therefore be incorrect.

Can depreciation of the property really reduce my rental tax?

Yes, where the taxpayer is entitled to deduct rental expenses.

Depreciation is intended to recognise the deterioration of the building over time.

Under the Spanish rules, effective depreciation for the property is generally calculated at up to 3% of the higher qualifying value, excluding the value attributable to the land.

Where the property was only rented for part of the year, the deductible depreciation must normally be restricted to the rental period.

It can therefore be one of the largest deductions available to an eligible landlord.

What happens if my repairs and mortgage interest are higher than my rental income?

There is a special rule that owners often overlook.

For eligible taxpayers, the combined deduction for financing costs and repair/conservation expenses cannot exceed the gross rental income from that property for the relevant period.

However, qualifying excess amounts can generally be carried forward and deducted during the following four years, subject to the same limits.

Importantly, this four-year rule relates specifically to these categories of expenditure. It should not be assumed that every unused rental expense automatically carries forward in the same way.

Filing, deadlines and problems with previous years

When do non-resident property owners have to file Modelo 210?

It depends on the type of income and the tax year.

For example, 2025 imputed income, which is currently being filed during 2026, can be declared until 31 December 2026.

From the 2026 tax year onwards, the filing window for imputed income moves to 1 April–31 December of the following year.

For 2026 rental income with tax payable and grouped annually, the new deadline is generally 1–20 April 2027.

The rules changed under Order HAC/623/2026, so owners should be particularly careful when comparing dates with older articles or previous-year filings.

Property sales follow a different timetable.

What happens if I discover that I should have filed Modelo 210 several years ago?

In most cases, it is better to regularise the position voluntarily rather than wait for the Spanish Tax Agency to contact you.

Where a tax return with tax payable is submitted voluntarily after the deadline and before a formal tax-office requirement, the late-filing surcharge generally starts at 1%, increasing by an additional 1% for each complete month of delay up to 12 months.

After 12 months, the general surcharge becomes 15%, with late-payment interest applying thereafter under the statutory rules.

Receiving a formal requirement before regularising can materially change the consequences.

How many previous years can the Spanish Tax Agency normally review?

The general statute-of-limitations period for determining a tax debt is four years, but saying simply “Hacienda can only look back four years” can be misleading.

The four-year period has specific starting points and can be interrupted by actions of the taxpayer or the Tax Agency.

In addition, information from older periods can sometimes remain relevant where it has tax consequences in a year that is still open.

This becomes especially important when owners regularise several old Modelo 210 returns or sell a property after many years of ownership.

Selling a Spanish property

Why does the buyer keep 3% of the price when a non-resident sells?

Because Spanish law requires the purchaser of property from a non-resident seller to withhold 3% of the agreed purchase price.

The buyer pays that amount to the Spanish Tax Agency through Modelo 211.

It is important to understand that this is not necessarily the seller's final tax.

It is a payment on account of the Capital Gains Tax eventually calculated on the sale.

The seller subsequently files Modelo 210 to determine the actual capital-gains liability.

What if I sell the property at a loss? Do they still retain 3%?

Usually, yes.

The 3% mechanism is based on the sale price and the seller's non-resident status — not on whether the transaction ultimately produced a profit.

Therefore, even someone selling at a capital loss can have 3% of the sale price withheld.

The seller must then file the relevant Modelo 210 and can request the refund of the excess withholding.

If there is no taxable capital gain, this can potentially mean recovering the full 3%.

How is the taxable capital gain calculated?

It is not simply:

selling price − original purchase price.

The calculation takes into account the legally determined acquisition and transfer values.

Acquisition costs can include qualifying taxes and expenses connected with buying the property, while certain costs connected with the sale can reduce the transfer value.

Improvements may also affect the acquisition value if properly documented.

Keeping the original purchase deed, invoices and evidence of acquisition and improvement costs can therefore make a substantial difference many years later when the property is sold.

I rented the property in previous years. Can depreciation affect the tax when I sell?

Yes — and this surprises many sellers.

Where a property has been rented, Spanish capital-gains rules require the acquisition value to take account of the relevant depreciation.

Importantly, the minimum tax depreciation can affect the eventual capital-gains calculation even where the owner did not actually claim that depreciation as an expense in previous rental returns.

This means rental history should be reviewed carefully when calculating a future property sale.

Looking only at the original purchase price and current sale price can produce the wrong result.

Other taxes foreign owners should not forget

Does Spanish Wealth Tax apply to non-residents?

It can.

Non-residents are generally subject to Spanish Wealth Tax only on assets and rights situated or exercisable in Spain.

Under the general state rules there is a €700,000 personal allowance, although regional legislation can materially change the calculation and non-residents may have access to the rules of the relevant Autonomous Community.

A return can also be required where the gross value of the assets and rights concerned exceeds €2 million, even if no tax is ultimately payable.

Most owners of an ordinary holiday home will not be affected, but owners of high-value Spanish assets should check their position rather than assume Modelo 210 is their only Spanish tax obligation.

I inherited or received a Spanish property as a gift. Does Modelo 210 still apply?

Yes, potentially — but there are two different stages to consider.

First, receiving the property by inheritance or gift can trigger Spanish Inheritance and Gift Tax.

Once you become the owner, the normal ongoing tax rules for non-residents begin to apply.

That means the property may subsequently generate:

• imputed income tax while used personally or left available;
• rental income tax if it is rented;
• Wealth Tax where the relevant thresholds are exceeded;
• Capital Gains Tax if it is eventually sold.

The value established when the property is inherited or gifted can also become important for future depreciation and capital-gains calculations.

Final thoughts

Spanish taxation for non-resident property owners is not particularly difficult once the different obligations are separated.

The problem is that the rules do not all arise at the same time.

You may pay IBI without realising that Modelo 210 also exists. You may rent the property for the first time and suddenly have deductible expenses to calculate. Or you may only discover missing returns when you decide to sell years later.

The safest approach is therefore to look at the full lifecycle of the property:

buy → own → use → rent → sell or inherit

and check the Spanish tax obligations at each stage.
