The Tax Agency will begin offering the service of preparing and submitting income tax returns at its offices from June 1st to 30th, 2026, with appointments available from May 29th to June 29th, 2026. This complements the telephone assistance and the special assistance plan in small municipalities, which allows taxpayers to receive personalized service until the end of the campaign, with availability being made available gradually.

The link to access the appointment booking service for personalized assistance services for the 2025 Income Tax Campaign is as follows: Tax Agency: Assistance and Appointment for the 2025 Tax Campaign

To mitigate the potential loss of appointments to the detriment of all taxpayers, the Tax Agency reminds citizens that they can cancel their appointment through any of the available means if they have decided not to use it. The routes provided are: Internet (with NIF/NIE or electronic DNI, electronic certificate, Cl@ve PIN or reference), "Tax Agency" App, automatic telephone (91 535 73 26 or 901 12 12 24) or appointment telephone for Income Tax with personal attention (91 553 00 71 or 901 22 33 44 from Monday to Friday, from 9 a.m. to 7 p.m.).
