The Administration can prevent disputes with the taxpayer by canceling, partially or totally, its actions vitiated by the presence of errors.
The cancellation is established upon request of the taxpayer from the same office that issued the document. The presentation of the self-defense request does not prejudice or suspend the right to appeal.
You can submit the request by filling out the self-defense form or alternatively it is possible to draw up an application on plain paper, indicating the information requested in the self-defense form and a summary of the facts.
