General Instructions

If there are current credits on your withholding tax account, this site will allow you to view and print your own credit balance. You can use this credit on your next withholding tax return filed with the Department.

Overpayments displayed on the Online Credit Inquiry System are based on the most recent business day's processing. For instance, if you are accessing this system on a Tuesday, information displayed will generally reflect the Department's Monday processing.
