I recently got two letters in the mail claiming that I was held overpaid benefits for two separate amounts. It says I need to file only one.Please reach out to FEA staff if you require any assistance when filling out the waiver. The Virginia Employment Commission (VEC) oversees and governs unemployment and any decision around unemployment benefits. What is an Overpayment Waiver? The overpayment notice contains the necessary information on how to submit an overpayment waiver request form. 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.
