When is the 2025 Income Tax Return due?

The 2025 Income Tax campaign will begin on 2 April, one day earlier than last year. From this date, taxpayers will be able to file their 2024 Income and Asset Tax returns online.

For those who prefer to file their tax return by phone or in person, the start dates will vary. Here are the key dates for the 2025 Income Tax Return:

From 2 April 2025 to electronically declare income and assets.
From 6 May 2025, if the Tax Agency itself prepares your declaration by telephone.
From 2 June 2025, for those cases in which the taxpayer decides to have their tax return prepared in person at the Tax Office. In this case, you must make an appointment and you will be able to do so between 29 May and 27 June.

When is the deadline for filing Income Tax Returns?

Although the start dates of the campaign vary depending on how you submit this tax model, the deadline for filing the Income Tax Return is fixed: 30 June 2025.

However, please note that for tax returns with a payable result and direct debit, the submission deadline will be Wednesday, 25 June.

How to file the 2024–2025 Income Tax Return?

During this Income Tax campaign, there will still be three ways to present the corresponding form. This is how each one works:

By Internet: If you choose to file your Income Tax Return using the Renta Web programme or the Tax Agency's mobile application, you can submit it in advance starting from 2 April 2025. However, with this option, you must identify yourself using one of the following methods: a digital certificate, the Cl@ve PIN system or the reference number from your previous Income Tax Return.
By phone: The Tax Agency staff will assist you in filing your Income Tax Return over the phone, for which you must request an appointment in advance. Ensure that you have all the necessary documentation readily available before the call.
In person: You can still visit a tax office in person to have a member of their team prepare and file your tax return. Please remember to schedule an appointment in advance and bring all relevant documentation regarding your income, expenses and other necessary details for the 2024 tax year.
