Anti-Fraud Mailbox: Who Qualifies and What You Get

Learn how to use the official mailbox to report tax fraud anonymously in Spain.

The Anti-Fraud Mailbox is a specialized tool provided by the tax authorities to allow for the reporting of suspected tax fraud.

Who it's for

This service is open to any citizen. Regardless of your professional status or your specific relationship to the person or business being reported, you are eligible to use this tool to alert the authorities to potential tax irregularities.

What you get

The primary benefit of this system is the ability to provide anonymous reporting regarding tax fraud. This mechanism is designed to help the tax agency identify and investigate dishonest practices. By using this mailbox, you can submit information about suspected tax evasion or other fraudulent activities while maintaining your anonymity throughout the process.

What it costs you

There is no financial cost to using this service. It is a free tool provided by the government to assist in maintaining tax compliance. You do not need to pay a fee to submit a report or to use the digital mailbox provided by the tax agency.

The catch to know

It is important to understand that this mailbox has a very specific purpose. It is intended solely for reporting matters related to tax fraud. You cannot use this system to report personal disputes, private disagreements, or non-tax-related grievances. If the information you have is not related to tax fraud, it is not the appropriate channel for your report.

How to apply

  1. Visit the official website of the tax agency.
  2. Search for the specific section dedicated to the mailbox or reporting (Denuncia fiscal).
  3. Follow the digital steps to input the details of the suspected fraud.
  4. Submit your report through the secure portal.
