HB0525, the Clean Truck Amendments, creates a new fee structure for older, high-emissions heavy duty vehicles and expands an existing tax credit for cleaner heavy duty vehicle purchases. Beginning January 1, 2026, owners applying for new registration of a heavy duty vehicle over 14,000 pounds gross vehicle weight and model year 2009 or older must pay a $250 heavy duty emissions compliance fee. In major nonattainment counties, the bill also imposes a $45 fee on registration or renewal of those same vehicles. Farm trucks, farm tractors, and vehicles already exempt from registration fees are excluded.
The bill also revises Utah’s clean-fuels funding and incentive programs. Fee revenue is directed to the Clean Fuels and Emission Reduction Technology Fund, which may be used for loans and grants supporting clean vehicle conversions, clean vehicle purchases, refueling equipment, and certain residential energy-efficiency grants. The bill expands the heavy duty vehicle tax credit in both the corporate and individual income tax codes, increasing credit amounts for 2026 through 2030 and broadening eligibility to include certain newer heavy duty vehicles registered in qualified counties, while also retaining eligibility for new natural-gas, electric, or hydrogen-electric heavy duty vehicles. It lowers the definition of a “small fleet” from 40 vehicles to 10 for purposes of reserving a portion of available credits.
HB0525 amends Utah Code provisions governing vehicle registration, clean-fuels funding, and heavy duty vehicle tax credits. It creates a new registration-related compliance fee under Title 41, adds a new section governing collection and deposit of those fees, and updates the Clean Fuels and Emission Reduction Technology Fund so the new revenue can support clean vehicle and emissions-reduction programs. It also amends the corporate and individual income tax credit statutes to increase credit amounts, adjust eligibility criteria, and change administrative rules for reservation, application, and carryforward of credits. The bill takes effect May 7, 2025, but the new fee provisions begin January 1, 2026.
The bill appears generally supportive of emissions reduction and fleet modernization, using both a fee on older high-emitting trucks and larger tax credits for cleaner replacements to encourage turnover. Even without recorded committee transcripts or vote history, the structure of the bill suggests a policy approach aimed at balancing environmental goals with incentives for businesses and vehicle owners to upgrade equipment. The absence of recorded votes or discussion in the provided materials means there is no documented public sentiment in the record beyond the bill’s design.
The main policy tension is between imposing new costs on owners of older heavy duty vehicles and expanding tax incentives for cleaner replacements. The fee applies to older, heavier trucks and is higher for new registrations than for renewals in nonattainment counties, which may draw concern from trucking operators, small businesses, and rural or agricultural interests; the bill partially addresses that by exempting farm trucks and farm tractors. Another likely point of contention is the increased tax credit amounts and the $500,000 annual cap, including the reservation of 25% of credits for small fleets and the reduction of the small-fleet threshold from 40 vehicles to 10, which could affect how benefits are distributed among larger and smaller operators.
