HR2424-119

What This Bill Does

The Modern, Clean, and Safe Trucks Act changes fuel excise-tax treatment for some renewable and alternative fuels used in transportation. It amends the diesel fuel, kerosene, renewable diesel, and biodiesel exemption rules by striking train and certain bus references while keeping the school bus reference. The practical effect is that renewable diesel, biodiesel, and alternative fuels used in trains or non-school-bus bus service would no longer receive the same exempt treatment, while school buses would remain protected. The bill is narrow tax policy aimed at equalizing or limiting special fuel exemptions outside the school-bus context.

Who Benefits and How

Federal highway and transportation trust fund users benefit if repealing exemptions increases taxable fuel receipts. School bus operators benefit because the bill preserves school bus exemption language. Tax administrators benefit from a narrower exemption category after train and non-school-bus references are removed. Fuel-tax parity advocates benefit from fewer special exemptions for covered train and bus uses.

Who Bears the Burden and How

Rail operators using renewable diesel or biodiesel lose exemption treatment for covered fuel use. Non-school-bus fleet operators using alternative fuels may face higher excise-tax costs. Renewable diesel suppliers serving rail and bus markets may see reduced demand from customers losing tax-preferred treatment. IRS excise tax staff must update guidance, forms, and compliance instructions for the revised exemptions.

Key Provisions

• Repeals train references from renewable diesel, biodiesel, and alternative fuel excise-tax exemption provisions.
• Repeals non-school-bus bus references from covered fuel exemption provisions.
• Protects the exemption language for school buses.
• Narrows transportation fuel tax exemptions rather than creating a new grant or emissions program.
