Double Taxation Agreement in Spain

If there is one way foreigners in Spain (including workers, investors, pensioners, and any other category) can avoid paying more tax than what they should, that is for sure double tax treaties.

But anything worthwhile has its costs, and in this case, that translates into the complexities of those accords and the difficulties in understanding how they actually work. But in this article we will answer all your doubts.

Next, you will find a complete guide on what these double agreements are, the 2 different ways they can be applied, what types of incomes are included, and the complete list of countries that do have a double tax agreement with Spain so that you can check if yours is on the list.

 

What is a double tax treaty?

 

A double treaty agreement is a deal between Spain and a foreign country that aims to help the foreigner in the Spanish territory avoid paying twice the same tax already generated and paid at source.

Let’s say, for example, that you are a tax resident in Spain (hence you pay income tax in the Spanish territory on the income you earn worldwide), who has generated income from another country, where you paid an initial tax on your profits.

If there was no double tax agreement between Spain and that country, once you declare that income in Spain, you would pay again that tax.

But thanks to this agreement, that part could be saved: the tax paid in the foreign source could be balanced against the tax paid in Spain.

Hence, these agreements allow you to pay the corresponding tax JUST in one country, and not in your residence country and also in the country where you received the income.

Spain currently has tax treaties with more than 90 countries all over the world, so it’s very likely that you can benefit from these treaties (at the end of this article you’ll find the complete list of these nations).

Nevertheless, the individual specificities of each treatment are what determine the way in which those double treaty conventions finally play out.

Let’s explore the 2 possible scenarios.

 

The 2 possible options when applying a double tax agreement

 

As we have already mentioned, the treaty itself contracted between Spain and the foreign country determines the method to be used in order to avoid double taxation.

In that sense, the first thing to be aware of is that those treaties just apply to certain types of incomes, so you must check if what you are declaring is included in the agreement (or not) and how.

If the answer is yes, there are different ways in which you can avoid paying taxes on that income twice (again, specified on the double tax agreement):

• The first of them is the exemption method. In that case, Spain would not apply its taxes on the income generated abroad, as it has already been paid at source
• On the other hand, we find tax credits against the taxes already paid in the foreign country, which means you can subtract the tax paid in the country where the income was generated from the tax you owe in Spain

In any case, keep in mind that it will never be possible to apply a deduction higher than the amount that has been determined in Spain. That is to say, if you can apply a deduction from a foreign country of, let’s say € 30.000, and in Spain you have to pay € 25.000, you will not be able to deduct more than those € 25k in Spain. 

 

Types of income affected by double taxation conventions

 

This foreign tax relief usually applies to:

• Foreign-source individual income
• Capital gains (which can include dividends, royalties, pensions, annuities, interests, etc.)
• Income as a non-resident; in case you are a non-resident but have generated that income from a Spanish source
• Corporate taxes
• Immovable Property Income
• Employment Income

On the other hand, inheritance tax is usually not covered in those agreements. That is because each country differs in the entity they choose to tax.

For example, in Spain it is the beneficiary the one taxed; whereas in the UK, it is the one who has passed away.

Nevertheless, no matter your country or situation, the first and most important thing to do is to first check if the category of income or profit earned can benefit from a double treaty convention, and which are the specific conditions that apply.

If you are from the UK, there you can find a guide that will help you out.

For the remaining cases, you can check what the specific treaty with your country defines by selecting your country of origin here.

What is a permanent establishment in Spain?

 

A permanent establishment (PE) in Spain is a concept in Spanish tax law that applies to foreign businesses with a significant, ongoing presence in the country.

For a foreign company or individual to have a PE in Spain, they must operate through a fixed place of business such as an office, branch, factory, or other location.

This fixed place must be used regularly to conduct business activities, indicating a certain level of permanence. Additionally, a dependent agent—an employee or contractor authorized to finalize contracts on behalf of the foreign company—can create a PE if they operate habitually in Spain.

Several situations can trigger a PE in Spain, including construction or installation projects lasting more than 6–12 months, and regular economic activities within Spain, even without a physical presence.

However, there are exceptions. Activities considered auxiliary or preparatory, like storage or purely supportive tasks, typically do not create a permanent establishment. Similarly, independent agents conducting business on their own account are usually exempt.

Having a PE in Spain means a company is liable for Spanish corporate taxes on profits from its local operations.

This includes corporate income tax, currently set at 25%, and potentially VAT registration if selling goods or services. Certain transactions may also be subject to withholding tax. Once registered, the PE must file annual tax returns and maintain records of its Spanish activities.

Foreign businesses with a permanent establishment in Spain are legally required to register with Spanish tax authorities, keep separate accounts, and adhere to Spanish tax compliance.

Understanding the rules for permanent establishments is essential for foreign businesses to avoid unexpected tax obligations and ensure compliance with Spanish tax laws.
