The UCR road tax is a mandatory tax that must be filed annually by transportation companies. The amount to be paid depends on the number of trucks operated by the transportation company.
The UCR (Unified Carrier Registration), in addition to being a mandatory tax for your company to transport cargo interstate, is also one of the prerequisites for your company's MC# (Motor Carrier number) to be active. Being up-to-date with this process facilitates the relationship with brokers, allowing them to deliver loads to your transportation company and enabling you to receive them at good prices.
Keep in mind that having an expired UCR can result in fines of up to $5,000 or the detention of your vehicle.
