Where’s My Check?

If you are waiting for a payment from the State, you can now access the Comptroller's (IOC) website and check the payment's status. The Vendor Payments page is a secure site and you will need your Taxpayer Identification Number (TIN).

On the left side of the IOC main page, click Vendor Payments. Next, the Vendor Login screen appears. You are required to type your TIN and click Ok. The next screen is Vendor Summary. Click Payments. The next screen is Vendor Warrants. Under the header Selection Criteria, scroll down to 494 – Transportation. At the bottom of the screen click Find Warrants. You have arrived at the Vendor Warrants screen which should include your warrant (check number and the date it was issued by the IOC.

If the payment amount you are expecting is not shown on the Vendor Warrants screen, one or more of the following may have occurred:

  1. The check/warrant is not being processed with the TIN entered on the Vendor Login screen,

  2. Your invoice has not been processed by I.D.O.T.

  3. Your invoice has not been processed by IOC.

If you have multiple TIN's please attempt the same process with all possibilities which will require you to go back to the Vendor Login screen. To avoid this in the future please include your preferred TIN on all future funding agreements. If you have exhausted all TIN possibilities, please contact your District Office. If it has been over three weeks from the date of the District's submittal to the Central Office please ask your District Office to make inquiries with the Central Office.
