Bill > HB0525

This bill addresses emissions reduction and incentives for heavy-duty vehicles in Utah, introducing several key provisions. Beginning January 1, 2026, the bill establishes a new heavy duty emissions compliance fee of $250 for initial registration and $45 for annual registration of vehicles over 14,000 pounds with a model year of 2009 or older, with exemptions for farm trucks and certain other vehicles. The collected fees will be deposited into the Clean Fuels and Emission Reduction Technology Fund. The bill also modifies tax credits for heavy-duty vehicles, increasing the credit amounts for qualified vehicle purchases between 2025 and 2030, with new provisions that encourage replacing high-emissions vehicles. Specifically, the tax credit amounts range from $7,000 to $15,000 depending on the year of purchase, and taxpayers can now qualify for credits by purchasing newer, cleaner vehicles and either proving the vehicle will primarily operate in-state or by selling or permanently disabling an older, high-emissions vehicle. The bill reduces the definition of a "small fleet" from 40 to 10 vehicles and maintains an annual aggregate tax credit limit of $500,000. These changes are designed to reduce emissions, encourage fleet modernization, and improve air quality, particularly in major nonattainment counties like Davis, Salt Lake, Utah, and Weber Counties.
