Overview
- The Tax Agency has activated its appointment system so taxpayers can reserve in-person help ahead of the office start of the 2026 filing campaign.
- Taxpayers can request appointments online with Cl@ve, a digital certificate, DNIe or the reference number, via the agency app, or by calling the automatic and staffed phone lines.
- Key deadlines remain: last day to arrange direct debits is June 25 and the filing window closes on June 30, so bookings are recommended early to avoid delays.
- The agency will send roughly 130,000 preventive letters in two phases to people whose fiscal data changed so they can check discrepancies and submit corrected or complementary returns if needed.
- The 2026 campaign follows a phased model that opened with online filing and now adds face-to-face assistance to help taxpayers with complex cases and reduce errors.
