Informant Leads Program

The Informant Leads Program coordinates and reviews information provided by the public to assist the CRA in identifying taxpayers who are violating tax laws. Lead information for this program pertains to domestic tax evasion allegations on the part of an individual or a business taxpayer. After reviewing elements of non-compliance with tax legislation, leads are provided to the corresponding compliance program for appropriate action.

For more information, see Frequently asked questions.

In January 2014, the CRA launched the Offshore Tax Informant Program (OTIP) that offers financial rewards to individuals with specific and credible information about major cases of international tax non-compliance resulting in more than $100,000 of additional federal tax being assessed and collected. Please visit the OTIP Web page for more information, including how to make a submission.

The CRA takes abuse of Canada's tax laws very seriously. When an individual or business does not fully comply with tax legislation, an unfair burden is placed on law-abiding taxpayers and businesses, and the integrity of Canada's tax base is jeopardized.

Beware of fraudulent communications:
The CRA is warning Canadians that fraudulent emails purporting to be from the Agency are currently circulating. See examples of these scams.
