Essential Guide to the 2025 Income Tax Return Campaign

The 2025 income tax return campaign officially commenced on Wednesday, April 2, 2025, giving taxpayers until June 30, 2025, to reconcile their accounts with the Tax Agency. This year, the Tax Office has slightly adjusted the schedule, moving the start date forward by one day compared to the previous year, which began on April 3.

For individuals looking to determine the outcome of their tax returns, the Tax Agency provides a convenient simulator on its official website. Taxpayers can file their declarations online via Renta WEB or utilize the agency's mobile application. To access their tax draft, individuals must possess a digital certificate, DNIe (National Identity Document), or Clave PIN. If these options are not available, it is possible to request a reference number to proceed.

It's important to note that the draft declaration can be completed and reviewed prior to submission, as it may include information that varies based on the taxpayer’s autonomous community of residence. To ensure compliance with the Tax Agency, here are some key dates to keep in mind:

  • April 2, 2025: The campaign begins with the option to request the draft and submit declarations online.
  • May 6, 2025: The appointment system opens for submitting declarations via phone.
  • May 29, 2025: The appointment system launches for in-person declarations.
  • June 2, 2025: In-person submission of declarations starts at Tax Agency offices.
  • June 25, 2025: Final day to file online if the declaration results in a payment due and to set up bank domiciliation.
  • June 27, 2025: Last day to request appointments either over the phone or in person.
  • June 30, 2025: Deadline to submit declarations by any means, marking the campaign's end.

Taxpayers need to be aware of the consequences of submitting their income tax return late. If an individual is obligated to file due to their financial situation and fails to adhere to these deadlines, the Tax Agency can impose penalties. Recent sanctions from the 2021 income campaign illustrated this point, where fines started at 1% and increased by an additional one percentage point for each month of delay. Those who delayed their return submission by over 12 months faced a surcharged penalty of 15% plus interest on late payment.

Additionally, some taxpayers might find their tax refunds blocked. If a person has submitted their income tax return and is due for a refund but has not received it, they should reach out to the Tax Agency. The agency can provide guidance on how to navigate the process to unlock their refund. It’s worth noting that these refund blocks may stem from outstanding debts with public administration authorities, such as traffic fines or unpaid property taxes like IBI (Property Tax) or registration taxes.

Being informed about these details can help ensure a smooth experience during this year's tax season.
