Retail units can issue local refunds for a maximum of $1,000. Refunds for $25 or less can be paid in cash. However, retail units cannot locally refund balances from customer trust accounts, regardless of the amount. Single drawer accountability offices are limited to cash refunds of $25, with the exception of PO Box cash refunds. Employees should not submit PS Form 3533 to the Scanning and Imaging Center for locally issued refunds.
