Information on the box from the previous year’s Income Tax return

To request the Renta file reference, it is necessary to provide the amount in box 505 of the Renta 2021 tax return filed.

Box 505 of the 2021 Income tax return corresponds to the "General net tax base subject to tax" and not to another amount or the result of the Income tax return.
