State Tax Refund Return Opt-In ProgramPrevent Future Fraudulent Refunds
Developed by the State Revenue Agencies and Nacha, the State Tax Refund Return Opt-In Program makes it easier for financial institutions to return tax refund credits in cases of suspected error or fraud.

What's In It For You?
Numerous financial institutions, as well as their state revenue agency customers, leverage Nacha Operating Rules and formats to recover questionable tax refunds sent via ACH credits. The effort aims to improve government and financial institution operations and processing and to prevent future fraudulent refunds.
