Should I register for IFTA in Colorado?

Colorado considers a qualified motor vehicle as one that is designed, used, or maintained for the transportation of persons or property that have:

  • Two axles and a gross vehicle weight or registered gross vehicle weight exceeding 26,000 pounds or 11,797 kilograms; or
  • Having three or more axles regardless of weight; or used in combination, when the weight of such combination exceeds 26,000 pounds, or 11,797 kilograms gross vehicle or registered gross vehicle weight.

Colorado does not include recreational vehicles in the IFTA tax unless they are used in conjunction with any business endeavor. Recreational vehicles include motor homes, pickup trucks with attached campers and buses when used exclusively for personal pleasure by an individual.

How do I apply for an IFTA license in Colorado?

To obtain an IFTA license, you should submit an application for an IFTA license using the International Fuel Tax Agreement (IFTA) Application (DR 7119).

Colorado carriers are automatically renewed if all IFTA returns are filed, all taxes, penalties and interest have been paid, and the carrier is in compliance with Colorado base jurisdiction laws. Renewals for your Colorado IFTA license and decals are sent to compliant carriers in December. IFTA licenses will not be renewed and may be closed for carriers who are not in compliance by December 31 every year. Carriers who are renewed and have been sent their IFTA license and decals have a two-month grace period (January and February) before they are required to display the IFTA license and decals for the current year for the state of Colorado.

What fees does Colorado charge for IFTA?

Currently, Colorado has no fees associated
with IFTA.

Does Colorado still require a quarterly fuel tax report if I didn't run during a quarter?

Yes, Colorado still requires you to submit a "zero" report even if no fuel or IFTA mileage was traveled in that quarter.

What is the penalty and interest rate for filing a late quarterly fuel
tax report?

There is a late penalty of $50 or 10% of the net tax liability, whichever is greater. Interest is computed on all delinquent taxes due to each jurisdiction at a rate of .4167% per month. Even if you have a net refund, interest still applies to each jurisdiction for any underpayment of fuels use tax to that jurisdiction and is calculated beginning the day after the due date of the return for each month, or fraction of a month, until paid.
