Report Tax Fraud In California

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). No rewards are offered for reporting this information.

Income tax fraud is intentionally paying less tax than you owe.

Examples of income tax fraud are:

Not filing state income tax returns.

Preparing documents, books, and records that understate the true income or overstate the expenses of a business.

Making false or fraudulent claims for refunds.

Questionable tax practitioner practices.

Failing to report all income received.

Opening and closing of new businesses to evade taxes.

Claiming to be a resident of another state while residing in California.
