The Department highly recommends using Revenue Online; tax rates are updated automatically around the 20th of the last month of period, performs calculations for you, and eliminate the possibility of lost returns.

Decals for New Vehicles

Adding vehicles to your IRP fleet does not mean you will automatically be issued IFTA decals. Once you are issued an IRP cab card, you must request IFTA decals by sending a web message or email with a copy of the registration. Mail is sent out at least once a week. If you need overnight delivery, provide a pre-paid FedEx label with a physical location (not a P.O. box).

Replacement Requests

To request decal or license replacements, a Request for Replacement form (DR7053) is required.

Mail not received or Returned

If mail is not received or gets returned; the address must be verified. Second replacement request after address changed/verified will require a prepaid FedEx label to be provided and can prevent account from being renewed.

Contacting the Fuel Unit

The best way to reach the Fuel Unit is through web messages from your Revenue Online account. Please allow us 24 hours to respond, before calling or emailing. Multiple inquiries reduce our ability to respond to you quickly.

  • Send us an email to DOR_FuelTax@dor.state.us.
  • Call us at 303-205-8205 option 1. Phone calls are usually answered within a few rings. If you have to leave a message, messages are usually checked and returned twice a day.
