The new service to obtain the reference number for 2023 is now available, which will allow you to manage all the services for the 2023 Income Campaign (and for previous campaigns).

The reference number you would have previously obtained is no longer valid, so you must obtain a new one. The box to enter to obtain the reference number is 505 of the 2022 Income Tax return.

You can obtain the reference number through the Tax Agency APP or at 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.
