Senate advances bill to collect diesel tax at the pump after lengthy industry debate

Senate Bill 164, which would change the way the state collects the special diesel fuel tax by levying it at the pump rather than through the current monthly permit/filing model, received extended floor and committee‑of‑the‑whole discussion Wednesday.

Sponsor Senator Craig Peterson argued the change would improve fairness and compliance. He cited post‑implementation data from neighboring states that showed gallonage did not decline after pump‑collection reforms and said the shift would help level the playing field among fuel sellers.

Opponents — including representatives of independent truck stops and some senators — cautioned that moving tax collection to the pump removes a cash float that many owner‑operators and small truck stops rely on. "If they have to pay that up upfront, it's devastating to them," said a representative for Western Petroleum marketers, noting some truckers purchase large volumes and rely on the deferred payment to manage operating cash flow.

The Utah State Tax Commission and the Utah Motor Transport Association countered that the current permit system leaves holes that allow underpayment; the commission said Utah is one of five states that does not collect this tax at the pump and that pump collection improves compliance. Tax Commission testimony described interstate agreements (IFTA/IRP) and audit processes that would work with pump collection to ensure fair apportionment.

Floor debate included multiple technical questions and a proposed amendment to require the tax commission to process refunds within a set period; that amendment failed. After multiple pro and con speakers and consideration in committee of the whole, the Senate recorded 21 ayes and 8 nays and moved the bill to third reading for further consideration.
