An increasing number of foreign individuals and companies have some kind of economic ties to Spain: a vacation home, a rental property, a real estate investment, or occasional income generated within Spain. In all these cases, the Non-Resident Income Tax comes into play—a tax that many foreign property owners are unaware of or confuse with other tax obligations, which can lead to avoidable penalties.
The Non-Resident Income Tax is the tax levied on income earned in Spain by individuals or entities that are not tax residents of Spain. Unlike taxes levied on residents, the IRNR focuses exclusively on income generated within Spain, regardless of the taxpayer’s tax residence.
The IRNR taxes a wide variety of income: from rent on a property located in Spain to dividends, interest, gains from the sale of a property, or income derived from economic activities carried out within Spanish territory.
IRPF, on the other hand, is the tax applicable to tax residents in Spain, who are taxed on their worldwide income—that is, on all their income regardless of the country in which it is generated.
Similarly, the Corporate Income Tax is levied on entities resident in Spain on their worldwide income, while non-resident entities operating in Spain are subject to the IRNR, unless they operate through a permanent establishment, in which case rules more closely aligned with those of the Corporate Income Tax apply.
The obligation to pay IRNR depends exclusively on the taxpayer’s tax residency, not on their nationality or legal or administrative residence.
Generally speaking, a person is considered a tax resident in Spain if they remain in Spanish territory for more than 183 days a year, or if they have the main center of their economic interests in Spain, regardless of their nationality.
Both individuals and legal entities that do not meet the criteria for tax residency in Spain are subject to the IRNR on income they earn within Spanish territory.
The law distinguishes between taxpayers who operate in Spain through a permanent establishment—such as a branch or a fixed place of business—and those who earn income on an occasional basis without such a structure; the latter case is the most common among foreign owners of residential property in Spain.
The tax may apply to a wide variety of income types, depending on the activity or asset generating the income.
Income earned from work performed in Spain, or from economic activities carried out on Spanish territory without a permanent establishment, is subject to the IRNR.
Dividends from Spanish companies, interest on accounts or financial products in Spain, and other income from movable capital also fall within the scope of the tax.
Income derived from real estate located in Spain—whether from rental or from mere use—is one of the most common scenarios for IRNR taxation among foreign owners.
The sale of real estate or other property located in Spain by a non-resident generates a capital gain that is also subject to this tax.
Foreign owners of real estate in Spain must pay special attention to how each situation related to their property is taxed.
If the property is not rented out and is used by the owner as a primary residence, the law requires the owner to report imputed income, calculated as a percentage of the cadastral value, even if no actual income has been earned from the property.
When the property is rented out, the income earned is taxed as real estate investment income, with the option to deduct certain expenses if the owner resides in the European Union or the European Economic Area.
The sale of a home generates a capital gain that is taxed separately, calculated as the difference between the property’s acquisition value and its sale value.
In real estate transactions involving non-residents, the buyer is required to withhold a percentage of the sale price and remit it on account of the seller’s IRNR (Non-Resident Income Tax), as a guarantee to the Spanish tax authorities.

The tax calculation varies depending on the type of income and the taxpayer’s tax residency.
The taxable base is generally determined based on the full amount of income received; however, in certain cases—such as the rental of real estate to residents of the European Union or the European Economic Area—necessary expenses incurred in earning that income may be deducted.
Generally, the tax rate applicable to residents of the European Union and the European Economic Area is 19%, while residents of third countries are taxed at 24%, unless a double taxation treaty establishes a different rate.
Residents of the European Union and the European Economic Area may deduct expenses such as property tax (IBI), homeowners’ association fees, insurance, repairs, or mortgage interest, whereas residents of third countries generally cannot claim these deductions on rental income.
Spain has double taxation treaties with numerous countries, which may modify the applicable tax rates or exempt certain types of income; therefore, it is advisable to check whether a treaty is in effect with the taxpayer’s country of residence.
Form 210 is the document through which non-residents report to the Tax Agency the income earned in Spain that is subject to IRNR.
It must be filed by any non-resident who earns income in Spain without a permanent establishment, whether from rent, imputed real estate income, capital gains, or any other type of income subject to the tax.
To file this form, you must have a NIE or NIF assigned by the Tax Agency, as well as documentation proving the income earned and, if applicable, the expenses you intend to deduct.
The deadlines vary depending on the type of income: imputed real estate income for personal use is filed annually; rental income without withholding tax is typically reported quarterly; and capital gains from the sale of real estate must be reported within several months of the transfer.
Form 210 can be filed electronically through the Tax Agency’s online portal—which is the mandatory method in most cases—and allows for tax payment via direct debit or direct charge.
In certain cases, it is possible to combine multiple sources of income from the same quarter into a single self-assessment return, provided they correspond to the same type of income and the same revenue code.
In addition to Form 210, there are other forms related to various transactions subject to the tax.
Form 211 is used by the purchaser of real estate from a non-resident to remit the withholding tax applied to the sale price, which is subsequently taken into account when settling the seller’s IRNR.
There are also specific forms for withholdings made by Spanish payers to non-residents, as well as for taxpayers operating in Spain through a permanent establishment, whose taxation is similar to that of corporate income tax.
Tax treatment varies significantly depending on the taxpayer’s country of residence.
Residents of the European Union and the European Economic Area benefit from a lower tax rate and the ability to deduct expenses, while residents of third countries are generally taxed at a higher rate and have fewer deduction options, unless a double taxation treaty modifies these rules.
Double taxation treaties signed by Spain with numerous countries can reduce applicable tax rates, exempt certain types of income, or establish mechanisms to prevent the same income from being taxed twice in different countries.
In addition to filing the corresponding tax return, non-residents with real estate in Spain have other obligations that should be kept in mind.
You must have a Spanish NIE or NIF to file any self-assessment tax return, and in certain cases—especially for residents outside the European Union—it may be advisable or mandatory to appoint a tax representative in Spain.
It is advisable to keep all receipts for income and expenses related to the property, as they may be requested by the Tax Agency to verify that the tax has been correctly paid.
Each type of rental income must be reported according to its own rules and deadlines; therefore, a single property owner may need to file different self-assessment returns throughout the year depending on the status of their property.
Certain errors are frequently made by non-resident taxpayers.
Having a residence permit or an NIE does not automatically mean you are a tax resident in Spain—and vice versa—which leads to confusion about which tax applies in each case.
Many homeowners mistakenly assume that if they do not rent out their home, they have no tax obligations whatsoever, when in fact they must report the imputed income corresponding to their own use of the property.
Claiming deductible expenses without verifying whether the taxpayer’s country of residence allows such a deduction is another common mistake that can result in an incorrect tax assessment.
Failing to meet the specific deadlines for each type of income—especially in the case of quarterly rent payments or real estate sales—is a frequent cause of avoidable penalties.
Failure to comply with the obligation to file the IRNR tax return carries financial consequences that you should be aware of.
Failure to file or filing late may result in late-filing penalties, late-payment interest, and, in the most serious cases, additional tax penalties.
It is possible to rectify a return that was not filed on time, although this usually involves paying the corresponding late filing penalties, which are generally lower the sooner the omission is corrected.
Yes. Even if the property is vacant or used for personal residence, the law requires you to report imputed income calculated based on its assessed value.
Generally, Form 210, although its content and filing deadline vary depending on the type of income being reported.
Only if you are a tax resident of the European Union or the European Economic Area; residents of third countries, as a general rule, cannot claim these deductions on rental income.
The sale generates a capital gain calculated as the difference between the purchase price and the sale price, subject to a specific tax rate, regardless of any withholding tax applied by the buyer at the time of the transaction.
Yes, Form 210 can be filed electronically, and payment can be set up via direct debit from a Spanish bank account, without the need to travel to Spain.
It is not mandatory, but it is highly recommended given the complexity of determining tax residency, correctly applying double taxation treaties, and avoiding errors that could result in penalties.
Understanding the IRNR is essential for those who earn income or own real estate in Spain without being tax residents. Buying a home directly can involve not only a high initial investment but also tax obligations, financing, maintenance, and asset management.

The Non-Resident Income Tax affects a growing number of foreign property owners and investors with financial interests in Spain, and a lack of understanding of this tax can lead to entirely avoidable surcharges and penalties. Understanding who is subject to this tax, how it is calculated based on the type of income and country of residence, and which tax return form to file in each situation allows you to meet your tax obligations without any surprises. Given the complexity of certain situations—especially regarding the sale of real estate or the application of double taxation treaties—seeking the assistance of a specialized tax advisor remains the safest option.
