(a) General. To get a credit or refund, a State must file a claim for a credit or refund of the overpaid amount with the Commissioner before the applicable time limitation expires. The State's claim for credit or refund is considered filed with the Commissioner when it is delivered or mailed to the Commissioner. Where the time limitation ends on a weekend, legal holiday or Federal nonworkday, we consider a claim timely filed if it is filed on the next Federal workday.
