Fuel Used for Exempt Purposes

Diesel Fuel Station    

Colorado allows a fuel tax exemption when the fuel is used for exempt purposes such as refrigeration units. IFTA (International Fuel Tax Association) carriers can apply for a refund of the Colorado fuel tax paid when the fuel is used for exempt purposes. To apply for a refund, contact the Department for a fuel tax refund account (see FYI Excise 7 "Tax Refunds for Exempt Use of Fuel").
