How IFTA Works in Colorado
IFTA (International Fuel Tax Agreement) allows motor carriers to report fuel usage across multiple jurisdictions with a single quarterly report. In Colorado, the process is seamless for both in-state and out-of-state drivers. This system helps simplify fuel tax compliance and ensures fair distribution of tax revenue between the states and provinces.
Colorado IFTA Vehicle Requirements
To qualify for IFTA in Colorado, your vehicle must meet the following criteria:
- It has two axles and a gross vehicle weight (GVW) exceeding 26,000 lbs.
- It is a combination vehicle with a GVW exceeding 26,000 lbs, regardless of how many axles.
It is used for transporting goods or passengers for hire.
CO IFTA Renewal and Decals
IFTA licenses and decals in Colorado are typically valid for one year and need to be renewed annually. Renewal notices are sent out by the Colorado Department of Revenue, and carriers are responsible for submitting renewal applications before their current registration expires. For the vehicle to be identified as IFTA-compliant, the decals must be visible on the vehicle.

Quarterly Colorado IFTA Filing Requirements
Colorado mandates that motor carriers submit quarterly IFTA reports that include mileage and fuel consumption for each jurisdiction they visit. Carriers must keep accurate records of the miles they drive and the gasoline they purchase in each state to ensure accurate reporting.
When Are Quarterly CO IFTA Returns Due?
| Quarter | Period Covered | Return Due Date |
|---|---|---|
| Q1 | January to March | April 30 |
| Q2 | April to June | July 31 |
| Q3 | July to September | October 31 |
| Q4 | October to December | January 31 |
What About Weekends and Holidays?
Your return is normally due the following business day if the deadline for your quarterly IFTA filing falls on a Saturday, Sunday, or holiday. For example, you will have until Monday of the following week (or the next available business day) to turn in your report if the last day of the quarter falls on a weekend. To prevent any late fees or issues, be sure to prepare ahead.
What to Expect from an IFTA Audit in Colorado
IFTA audits in Colorado can be initiated if the state believes there are discrepancies or irregularities in the filed reports.

Carriers should retain all fuel receipts, mileage logs, and other relevant documentation for at least four years in case of an audit.
