Are you a retired expat living in Spain? Wondering whether your foreign pension needs to be declared or taxed?

We break down everything about the income tax return for foreign pensioners: when you need to declare, what exemptions may apply, and how to avoid double taxation.

How and Where Should I Pay Tax on a Pension I Receive from Another Country?

If you live in Spain and are considered a tax resident (you spend more than 183 days a year here or your economic interests are based here), you must declare your worldwide income—including foreign pensions, as confirmed by the Spanish Tax Agency.

However, whether you actually pay tax on that pension in Spain depends on the tax treaty between Spain and the country where your pension comes from:

  • If the treaty gives Spain taxing rights, you’ll pay Spanish income tax on the pension.
  • If the other country retains taxing rights, you may be taxed there—but you may still have to declare it in Spain (and possibly deduct the tax paid abroad).

💡 Spain has double taxation agreements with many countries (like the UK, Germany, France, USA…), which are designed to avoid paying twice on the same income.

To get it right:

  1. Check the treaty between Spain and the country where your pension is from.
  2. Declare the income in Spain if you’re a tax resident.
  3. Use deductions or exemptions where allowed to avoid double taxation.

How to declare foreign pensions in your income tax return

If you’re a tax resident in Spain, you must declare all income worldwide, including foreign pensions. These pensions are reported under the “monetary remuneration” section as income from work, since the Spanish Tax Agency classifies pensions as earned income (rendimientos del trabajo).

🏦 What if Tax Was Withheld Abroad?

  • No withholdings in the origin country: You pay tax on the full amount in Spain.
  • Withholdings applied abroad: You must complete box 96 under “Other deductions – International double taxation” in the Spanish tax return (IRPF).

To avoid double taxation:

  1. Enter the gross pension income in the relevant field.
  2. Enter the amount withheld abroad in the corresponding box.

The system will automatically calculate the deduction, so you don’t pay tax twice.

⚠️ What Happens If You Don’t Declare?

Failing to declare foreign pensions can lead to several issues:

  • It may affect your eligibility for the minimum pension supplement, which is designed to top up pensions below the minimum threshold.
  • If you received the supplement without declaring other income (like a foreign pension), Social Security can request a refund of the unduly received amounts, according to Social Security.

🧠 Spain requires declaration of any foreign pension income, even if the country of origin does not require a minimum contribution period to grant it.

Exceptions in Tax Treaties: What You Should Know

Tax treaties between Spain and other countries define which country has the right to tax each type of income:

  • Sometimes, only the country of residence can tax it.
  • Other times, only the country of origin has that power.
  • In many cases, both countries can tax the same income—but the country of residence must apply mechanisms to avoid double taxation.

⚠️ Don’t just think of salary—investment returns and capital gains also count as taxable income under these treaties.

Frequently asked questions

Do I have to declare my foreign pension in Spain?
Yes. As a tax resident in Spain (more than 183 days a year or your main economic interests in the country), you must declare your worldwide income, including pensions from other countries. This obligation doesn't depend on the conditions the paying country sets regarding years of contributions or the type of pension in its country of origin.
Will I be taxed twice on my foreign pension?
Not necessarily. Spain has double taxation agreements with countries such as the UK, Germany, France or the United States. The result depends on the treaty and the type of pension: some can only be taxed in Spain, others only in the paying country and others in both. When both can tax it, Spain normally applies the international double taxation deduction. In some cases the treaty exempts the pension in Spain, but it still counts to set the rate on your other income. If only Spain can tax it, ask the paying country how to recover any tax withheld. With no treaty, the deduction applies if the pension was also taxed abroad.
Where do I declare my foreign pension in my tax return?
Foreign pensions are declared as income from work (rendimientos del trabajo). If the treaty only lets the paying country tax it, the pension is exempt in Spain, although in some cases it still counts to set the rate on your other income. Tax withheld abroad doesn't always give you a deduction in Spain: the international double taxation deduction normally applies when the treaty lets both countries tax the pension (and only up to the tax the treaty allows the paying country to charge) or when there's no treaty and the pension was also taxed in the paying country. If the treaty only lets Spain tax it, ask the paying country how to recover the tax it withheld.
What happens if I don't declare my foreign pension?
Not declaring it can lead to penalties and surcharges from Hacienda. It can also affect the minimum pension supplement: if you've received it without declaring other income, the Seguridad Social (Spanish Social Security) can ask you to repay the amounts unduly received, plus the interest accrued during the period of irregular payment.

Your foreign pension, declared right

If you live in Spain and receive a pension from abroad, you will usually need to report it on your Spanish income tax return, and double taxation treaties can stop you from paying twice. Getting it right matters.
