Tax Fraud

Tax fraud is theft

When someone deliberately falsifies a tax return to either reduce the amount of tax owed, or obtain a refund that isn't deserved, that's tax fraud. And tax fraud is really theft.

Tax fraud occurs in many ways, including:

  • Inflating deductions on an income tax return to get a bigger refund
  • Claiming withholding that a person isn't entitled to
  • Stealing someone's identity to gain that person's tax refund

Most Idaho taxpayers file accurate returns on time and pay the tax they owe as required by law. But a few taxpayers purposely evade their responsibility, and this increases costs for everyone.

Online referral form

If you suspect or know of an individual or business that's violating Idaho tax laws, you can report this activity online through Taxpayer Access Point (TAP).

You can also use our downloadable Form IRF (Information Referral Form (05-29-2015)) .

Your identity will be kept confidential. However, it helps if you provide your contact information in case we have questions about the information you submitted. Idaho law prohibits disclosing the status of any investigation and/or any resulting civil or criminal case. We can't give rewards for information.

The IRS has more information about reporting suspected tax fraud on its website,

Fairness is our goal

We review every referral to determine the issues involved and whether a violation has occurred. The Tax Commission is dedicated to investigating allegations of tax fraud and helping victims of identity theft in order to promote public confidence in the tax system.
