How to file a Tax Complaint

Filing a tax complaint through the Tax Agency's website can be done using electronic identification (certificate or electronic ID), the Cl@ve system, or without identification.

The complaint must contain as much known data as is necessary for the identification, by the Inspection body, of the persons reported, such as name and two surnames or company name in the case of legal persons, NIF , address, company name if applicable, etc.

The data and facts reported must be sufficiently specified and accompanied by the documentation available to prove such facts.

A downloadable tax complaint template is available for you to submit in person at the Tax Agency Delegation or Administration closest to your home or send by post to any Tax Agency office.
