The General Tax Directorate (DGI) is carrying out the campaign of sworn declarations of the Income Tax of Physical Persons (IRPF), and the Social Security Assistance Tax (IASS).
Taxpayers who have to file a return have at their disposal the forms of online affidavit with the information uploaded from the work activity carried out in 2021.
that way dependent workers can confirm or modify the information adding deductions, rental credits, or correcting income or withholding. It is only required to have a digital identity key. And independent workers can access the same form and must complete the income and withholdings for their activity.
The DGI published a video explaining how to make the declaration step by step. Until August 29 you can submit the online affidavit on time.
