Do any states charge extra UCR fees beyond the federal schedule?
No. The UCR fee schedule is set federally under 49 USC §14504a and is uniform across all participating states. The Tier 1-Tier 6 fees are the same regardless of which participating state the carrier files through. States cannot charge "extra" UCR fees beyond the federal schedule, though they may add their own state-level motor-carrier registration fees that are separate from UCR.
The UCR fee structure is federally uniform. Tier 1-Tier 6 fees are set in 49 USC §14504a and apply identically across all 41 participating states. A carrier in California pays the same Tier 1 fee ($46 in 2025) as a carrier in Texas or Maine; the participating state collects the fee but does not modify it.
Some states do impose separate state-level motor-carrier registration fees in addition to UCR. These are not "extra UCR" fees — they are independent state programs (state intrastate authority registration, state DOT permits, state-specific MCS-150 supplements) that apply to carriers operating in those states. The state fees are paid separately to the state agency, not through the UCR portal.
For carriers comparing total compliance costs across base-state options (carriers in non-participating states choosing which participating state to file through), the UCR fee itself is uniform. The differentiator is the state-specific motor-carrier registration overhead that may layer on top in some states. For most carriers, this is a small consideration relative to the federal UCR fees themselves.
For carriers who see "UCR" line items significantly different from the federal schedule, the discrepancy is typically a service-provider markup or bundled state fees, not actual UCR variation. Carriers should verify the federal UCR fee schedule against any quoted UCR cost to confirm the federal portion is correct.
