It's just an extra step we're taking to verify the returns we process and make sure refunds go to the right person. Schools must refund tuition and fee payments to students in accordance with their established refund policies, so that the students can resolve over-payments.The primary letter we use to request information about a return is Form DTF948 or DTF948O, Request for Information (RFI). Many times when a third-party payer mistakenly pays a dental provider, the payer will request a refund of the overpaid amount. Overpayment refunds of vehicle and business tangible property taxes will be sent within 2 to 4 weeks from the date of the payment or exoneration. Call the Virginia Department of Taxation at 8043678031. They can look up your account and issue you a refund.
