Reporting Income Tax Fraud
If you believe an individual or company is not complying with California's personal income tax or corporate income and franchise tax laws, you can report that information to Franchise Tax Board (FTB). We do not offer rewards for reporting this information.
Income tax fraud is intentionally paying less tax than you owe.
Examples of income tax fraud are:
- Failing to report all income received.
- Claiming to be a resident of another state while residing in California.
- Making false or fraudulent claims for refunds.
- Not filing state income tax returns.
- Questionable tax practitioner practices.
- Opening and closing of new businesses to evade taxes.
- Preparing documents, books, and records that understate the true income or overstate the expenses of a business.
