Who licenses for IFTA in Colorado
Any Colorado-based entity operating qualified motor vehicles in two or more IFTA jurisdictions may take an Colorado IFTA license in lieu of trip permits, with Colorado as the base jurisdiction: the place where the vehicles are registered and where operational control and records live.
Qualified means the vehicle passes the axle and registered weight test the Department of Revenue publishes, alone or in combination. Leased operations follow the lease: a written lease that puts reporting on the lessor keeps the lessee out of it.
Applying for an Colorado IFTA license
You apply through the Department of Revenue, file the application with your carrier information, and receive your license and decals once approved. The application form and the fee the state charges are sourced fields on this page.
Quarterly filing
Once licensed, you file one IFTA return each quarter covering every jurisdiction where you burned fuel. The return is due the last day of the month after the quarter closes. The filing schedule and the penalty for a late return are sourced fields on this page.
The tax rates live in the quarterly matrix
IFTA rates change every quarter, so we keep them in one refreshed store instead of copying them onto every state page. The current quarter is 3Q 2026. Use the IFTA rates by state table for the full matrix, or the IFTA calculator to run your miles and gallons against the current rates.
What pairs with IFTA
IFTA and IRP travel together: the same interstate operation that needs a fuel tax license usually needs apportioned plates through Colorado IRP. If you are still setting up, the full order of operations is in start a trucking company in Colorado.
