Income Tax Return: Key dates and main changes for the 2025 tax year

Did you know that many unemployment benefit recipients are no longer required to file a tax return? Or that there is a new deduction for low-income earners that you may not have heard about yet?

The regulations applicable to the imminent start of the personal income tax and wealth tax filing season introduce relevant changes for employees, self-employed individuals, property owners and investors, and knowing them in advance makes a difference.

In this article, we break down the main updates for the 2025 tax year and the key dates you should keep in mind when filing your return.

Key dates

• April 8 → Official start of the campaign
• June 25 → Deadline to set up direct debit payments (for payable returns)
• June 30 → Official end of the campaign

Main changes to consider

1. Unemployment benefit recipients are no longer required to file

One of the most anticipated changes: the obligation to file an income tax return is definitively removed for those whose only income comes from unemployment benefits.

However, the obligation remains if any of the following circumstances apply:

• They have had another payer from whom they received more than €1,500 and the total employment income exceeds €15,876.
• They have been registered as self-employed during the tax year.
• They are part of a household receiving the Minimum Vital Income (IMV).

Even if you are not required to file, it may be advisable to do so if the result is a refund. We recommend consulting your advisor.

2. New deduction for low-income earners

Law 5/2025 introduces a deduction of up to €340 for workers with gross annual income of up to €16,576 (equivalent to the 2025 minimum wage). The deduction is gradually reduced for income between €16,576 and €18,276, at which point it disappears completely.

This measure provides direct tax relief for lower-income workers and complements the new minimum thresholds of the tax system.

3. The filing threshold is linked to the 2025 minimum wage

Individuals who have earned exclusively the 2025 minimum wage (€16,576 annually in 14 payments) will not be required to file a tax return, unless other circumstances предусмотрed by the regulations apply (second payer, capital income, etc.).

This change updates the filing threshold to the new minimum wage level, extending the exemption to more taxpayers than in previous years.

4. New top bracket for savings income

A new 30% tax rate is introduced for capital gains and savings income exceeding €300,000. Lower brackets remain unchanged.

This measure mainly affects high-net-worth individuals, large asset transfers and significant capital income, and should be considered in the tax planning of investors and business owners with substantial gains.

5. Deduction for energy efficiency improvements in housing

Unlike previous years, not all deductions for energy efficiency works are extended. In 2025, only the 60% deduction for energy improvement works in entire residential buildings remains in force.

Key aspects to consider:

• Payments must be made by card, bank transfer or nominative cheque. Cash payments are not allowed.
• Subsidies received for carrying out these works reduce the base of the deduction.

6. Tax-exempt compensation without the need for a court ruling

Organic Law 1/2025 extends the scope of tax-exempt compensation in personal income tax in three relevant cases:

• Civil liability for personal damages: the exemption applies to compensation paid by insurers within mediation agreements or other alternative dispute resolution mechanisms, without the need for a prior court ruling.
• Employment dismissal: compensation agreed before administrative bodies prior to judicial proceedings is also exempt, as it is not considered derived from agreement or contract.
• Child support payments: exemption includes maintenance payments established in regulatory agreements formalized before the Court Clerk or in a notarial deed.
