June: The Key Month of Income 2025 and the Surprise Letters from the Treasury

The countdown to the tax return has begun, but are you prepared for the notices from the Tax Agency?

The calendar marks the beginning of June, a month that for millions of Spaniards means the final stretch to comply with one of the most important tax obligations: the income tax return for the year 2025. The deadline, immovable, looms over the June 30a deadline that requires speed and precision from all taxpayers.

This year's campaign has demonstrated remarkable agility. In just two months, they have already registered 15.2 million statementswhich represents an increase in 4.7% compared to the previous year. This data is even more significant if we consider that the campaign began six days later than in 2025, reflecting greater participation and, perhaps, better preparation on the part of citizens.

The Tax Agency has not only received a flood of declarations, but has also expedited the refund process. To date, 8.27 million taxpayers have already seen the corresponding amount deposited into their accounts, adding up to a total of 5,710 million euros. These figures show that 75.5% of refund requests have been processed, covering 61% of the total amount to be returned.

However, not everything is a bed of roses for those who have already submitted their declaration. Some taxpayers could receive a letter from the Tax Agency at their home. Far from being a cause for alarm, it is preventive notices. These are aimed at those who, before paying the Personal Income Tax (IRPF), decided to modify some data initially provided by the Agency itself.

In order to avoid possible errors or omissions arising from these modifications, the Tax Agency has launched a proactive communication initiative. More than 50,000 letters have already been sent, urging recipients to “assess whether or not they should present a supplementary declaration“, adapting your information to that held by the AEAT. This measure seeks to guarantee the accuracy of the data and prevent future complications.

The importance of attending to these notices is capital. The omission or late correction of errors could lead to undesired consequences, such as the imposition of fines or regulations. The Treasury estimates that the total number of preventive letters sent will amount to 130,000. Last year, this strategy proved effective: more than 45,000 corrective declarations They were presented after receiving a notice, thus avoiding inspections, late payment interest and possible sanctions.

The income tax return is a fundamental pillar of our tax system. Diligently fulfilling this obligation not only avoids problems, but also contributes to the maintenance of public services that benefit the entire society. The fluid communication and proactivity of the Tax Agency, as demonstrated by these preventive letters, are key tools to facilitate this process for citizens.

The month of June is, therefore, a period of maximum fiscal activity. It is time to carefully review the information received, to assess the modifications made and, in case of doubt, to act diligently to present a declaration that faithfully reflects the economic reality of the taxpayer. Collaboration between the Treasury and citizens is essential for a fair and efficient tax system.

Let us remember that the information provided by the Tax Agency is a helpful tool, but the final responsibility falls on the taxpayer. The 2025 income campaign is an opportunity to strengthen this responsibility and ensure that our tax obligations are met without margin for error. June 30 is the deadline, but acting early is always the best strategy.

The agility in returns and the increase in the number of declarations submitted are positive signs of a citizenry increasingly committed to their fiscal duties. The preventive letters initiative reinforces this commitment, offering a way to correct possible imbalances before they become major problems. It is one more step towards a more transparent and collaborative tax management.

In short, June is not only the countdown month for tax returns, but also a crucial period for communication and correction. Being attentive to notifications from the Tax Agency and acting accordingly can make the difference between a smooth process and a more complex tax situation. Information is power, and in this case, information from the Treasury can be your best ally.

Tax planning should not be limited to the time of filing. It is a continuous process that spans the entire year. However, the income campaign is the peak moment where the results of that planning are consolidated. Preventive letters are a reminder that the Tax Agency is attentive and willing to help maintain the accuracy of the information, always for the benefit of the taxpayer and the system.

Technology and communication are playing an increasingly important role in tax management. The preventive letters initiative is a clear example of how the public administration can use these tools to improve the relationship with citizens and facilitate compliance with tax obligations. A proactive approach that is certainly appreciated.
