One of the most important campaigns of the year has begun in Spain: filing the IRPF tax returns for 2025. For millions of residents, this is not just a formality but a mandatory process that determines whether they receive a refund of overpaid taxes or need to pay additional amounts to the state. This year, key dates and submission procedures have changed, directly impacting financial planning and the need for consultations.
Starting April 8, tax returns can be submitted online. This means anyone wishing to quickly resolve their tax matters can use the Renta WEB service or the Agencia Tributaria mobile app. Several identification methods are available: digital certificate, DNI, Cl@ve, or a reference number. The system offers a preliminary draft of the return based on the tax authorities’ available data. However, it is essential to carefully review all information—mistakes or omissions can lead to fines or lost money.
Filing calendar
During the first weeks, the campaign is conducted exclusively online. From April 29, appointments open for telephone consultations under the Le Llamamos program. Beginning May 6, tax office specialists will call those who have registered to help fill out and submit their tax return. For many, this is a convenient way to avoid queues and receive assistance without visiting an office.
In-person submissions are only possible starting in June. From May 29, you can book an appointment at the office, and from June 1, face-to-face service will be available. This is particularly relevant for those who prefer to handle documents with support from tax office staff. Remember: the last day to file your return is June 30, while those who owe additional tax must ensure automatic payment by June 25. Consultations can be booked through June 29 inclusive.
Process highlights
The IRPF declaration for 2025 covers income received during the previous year. This approach is due to taxes being withheld gradually, with the final calculation done after the year ends. If you overpaid throughout the year—such as due to excessive withholdings or deductions—you will be refunded the difference by the tax office. Otherwise, you will need to pay the outstanding amount. Payment can be made in a single transaction or in two stages—in June and November—by providing your IBAN when filing.
To obtain a phone or in-person consultation, you must prepare all documents in advance: income statements, property details, and bank information. According to RUSSPAIN, many taxpayers encounter errors in preliminary calculations, so it is essential to double-check every detail. This is especially important in case of changes in marital status, changes of residence, or receiving new types of income.
Key points
This year, special attention is being paid to the accuracy of data and timely submission. Missing deadlines or providing incorrect information can result in penalties. For those dealing with the process for the first time, the tax office website offers a detailed guide and a list of citizen categories required to file a declaration. Not everyone is obligated to report: much depends on the amount of income and its sources.
According to RUSSPAIN, recent years have seen an increase in requests for assistance via phone and online. This is linked to the rise of self-employed individuals and changes in household income structures. In 2024 and 2025, many people faced new deduction rules and rate adjustments, complicating the process of filing declarations independently.
In previous years, the IRPF filing campaign was marked by long lines at offices and technical issues on the tax office website. In 2024, for example, many complained about delays in refunds and difficulties booking consultations. In 2025, some of these problems were addressed by expanding online services and increasing the number of phone operators. However, experts point out that careful completion of the declaration remains the key to success, and timely submission helps avoid fines.
