Having just finished this year’s Renta (annual tax declaration), I discovered a money-saving tip that many might have overlooked, and I wanted to share it with you all! This is especially for those who own property in their home country or other nations—this info could save you some coffee money!
As we all know, as tax residents in Spain, our worldwide income must be declared here, and that includes income from property held abroad. However, what many people don’t realize is that if you’ve already paid taxes on your foreign property to the local government there, you can apply for a deduction called the ‘International Double Taxation Deduction’ to avoid being taxed twice in Spain.

How to Apply for This Deduction?
The process isn’t too complicated. The key is to fill in the information correctly in the corresponding section when you file your Renta. The core principle of this deduction is: you’ve already paid tax abroad, so the Spanish Tax Agency deducts the amount you paid abroad from your total Spanish income tax liability. Of course, there is a cap on this deduction; it cannot exceed the amount of tax that would be payable on that same income under Spanish tax rules.
Simply put, when you file, you need to submit proof of taxes paid abroad. For example, if you’ve rented out your house in your home country and paid personal income tax to the local tax authorities, that tax payment certificate is the key document. Without it, the tax agency will not approve the deduction. Therefore, it’s essential to get into the habit of keeping these payment records and receipts, much like you would for other tax benefits such as capital gains tax relief.
What Key Information Do You Need to Prepare?
Here’s a checklist of the information you’ll typically need to fill in or have ready:
| Required Information | Description |
| Foreign income from the property | E.g., rental income, which needs to be converted to Euros. |
| Taxes paid abroad | The amount of tax paid in the property’s country related to that income. |
| Proof of tax payment | Official tax payment certificate issued by the tax authority in the property’s country. |
| Basic property information | Address, value, etc., for tax calculation and verification. |
A few final reminders: this deduction policy primarily applies to Personal Income Tax (IRPF), and it’s a different concept from property tax (IBI) or wealth tax (Patrimonio), so don’t get them confused. Additionally, the details of the tax treaty between each country and Spain may differ. If you are unsure about your specific situation, particularly when dealing with various property taxes like the Plusvalía, the safest approach is to spend a little money to consult a professional Gestor. They will handle all the details for you, ensuring everything is done correctly. Hope this little tip helps everyone!
