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.

  • Your identification number is the 8 digit number issued to you by the Missouri Department of Revenue to file your business taxes. It can be found on any correspondence sent by the Department of Revenue, including your sales tax license if you make retail sales.
  • Your PIN is a 4 digit number located on the cover of your voucher booklet or return.
