Complete the International Fuel Tax Agreement (IFTA) Application (DR 7119) in its entirety, including copies of proof of good standing with the Secretary of State, Federal Employer Identification Number (FEIN) provided by IRS, and copy of valid vehicle registration. Retain a photocopy of the completed form for your records.

If you have a lease agreement in effect, the lessee is responsible for filing the IFTA Application. The lessee is responsible for requesting the decals, as well. Both the lessor and the lessee must complete the IFTA Lease Agreement Certificate (DR 7511) and provide a copy of the lessor’s vehicle registration.

If an applicant is an individual with or without a trade name, a Social Security Number (SSN) is required as well as a Federal Employer Identification Number (FEIN).

As the base jurisdiction, Colorado will issue one IFTA license to the qualified applicant. The IFTA license is valid for the current calendar year and expires December 31st.

The applicant is required to make copies of the IFTA license, so that one copy can be carried in each qualified motor vehicle. A vehicle will not be considered operating under IFTA unless there is a copy of the license in the vehicle.

Failure to display decal or copy of the IFTA license may result in the vehicle operator being required to purchase a Trip Permit. Carriers may obtain a Trip Permit at any Colorado Port of Entry.

The completed license application can be submitted in one of the following ways. The following methods of submitting applications without compliance issues will be processed within 5 business days after receipt.
