General Information


Motor Carrier Services maintains the International Registration Plan (IRP) and the International Fuel Tax Agreement (IFTA) for the Jurisdiction of Utah. These programs are reciprocity agreements among states of the United States, the District of Columbia and provinces of Canada, providing for payment of apportionable fees and fuel taxes on the basis of total distance operated and fuel usage in each jurisdiction.

Note: Sales tax is due on any vehicle purchased for intrastate travel regardless of weight. However, if a vehicle is IFTA qualified (over 26,000 pounds) and registered for IRP (interstate travel), it may be exempt from sales tax.
