Open ProvincesSuspected tax or benefit fraud: submit a useful lead to the CRA
Separate a lead from a personal dispute, provide verifiable facts and use the correct domestic or offshore program without investigating yourself.
Do not enter an account, office or device and do not steal documents. Submit only information obtained lawfully.
Choose the program
The Leads Program covers non-compliance in Canada. Significant offshore assets, correcting your own return, a scam against you or a service dispute use other channels.
Describe the facts
Provide identity, business, address, period, approximate amounts, type of income or benefit and how you know. Separate evidence, observation and rumour.
Organize documents
Attach only relevant copies and explain each item. Remove unrelated third-party data and keep the originals.
Submit without expecting a personal outcome
The National Leads Centre accepts information online, by phone or mail. The CRA normally cannot provide detailed follow-up about compliance action.
