When your tax payments exceed what you owe, it's called an overpayment credit. You'll automatically be refunded this credit. You can ask us to apply the credit as an advance payment toward next year's taxes instead of sending you a refund. When can I expect to receive my refund? You'll receive it in 4-6 weeks if you don't owe other taxes or debts we're required to collect. What can I do if I don't receive my refund in four to six weeks? Call us at the number on your notice.
