The Tax Agency has a registry of powers of attorney that allows the registration of powers granted by individuals and legal entities to carry out tax procedures online, without having to travel to the offices.

Individuals, legal entities, unclaimed estates, communities of property and other entities that, lacking legal personality, constitute an economic unit or separate estate that is subject to taxation, may grant power of attorney to carry out, on their behalf, certain tax procedures within their personal scope. The power of attorney can be granted, in turn, to one or to several parties, including both individuals and legal persons.

If you want to carry out your procedures at the Tax Agency headquarters through a representative, you can choose to delimit the scope of the power you grant, by individually choosing each of the procedures to which you want it to be extended, or to empower to carry out one or several categories, of those detailed in the following link:

Types of power of attorney

The procedure to register the power can be carried out by the grantor (the person who gives the power):

• Online, using an electronic certificate, electronic ID or Cl@ve PIN.

• By personal appearance at the offices of the Tax Agency.

• By public document or private document, with notarized signature, presented to the Tax Agency.

You can consult the powers of attorney you have granted, you can also revoke them at any time or renounce a power of attorney that has been granted to you.
