Colorado Tax Rate Change
The fuel price in Colorado includes two fees in addition to the fuel tax. For rate information, go to Tax.Colorado.gov/IFTA-forms. The Road Usage fee will increase to $0.06 per gallon on July 1. This fee is automatically included in the tax rate and is programmed into your Revenue Online return.
Kentucky Fuel Tax Rate Reduction
