General Instructions

You may have current credits on your sales/use tax account, and this site will allow you to view and print your own credit balance. You may use this credit on your next sales/use 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.

  • Sales/use tax credits cannot be used towards withholding taxes or any other taxes.
  • Withholding tax credits cannot be used towards sales/use taxes or any other taxes.

  • Your identification number is the 8 digit number issued to you by the Missouri Department of Revenue to file your business taxes and is included on your sales tax license.
