The new service for obtaining a reference number for 2024 is now available. This service will allow you to manage all services for the 2024 Income Tax Campaign (and previous campaigns).

The reference number you previously obtained is no longer valid, so you must obtain a new one. The box to enter to obtain the reference number is 505 on the 2023 Income Tax Return.

You can get the reference number using the Tax Agency APP or by clicking on the following link: Tax Agency: Reference number .

In any case, we remind you that by registering in Cl@ve you will be able to access all Income Tax procedures without having to get your reference number.
