For years, I’ve urged Governor Newsom to suspend the annual gas excise tax increase and pause regulatory measures that raise prices for consumers, but those calls have gone unanswered. It’s past time for Sacramento to stop these harmful price hikes, prioritize domestic energy production, and ease the burden on hardworking Californians instead of adding to it.

Valadao reiterated his opposition to California's annual gas excise tax increase and called for state action to suspend the increase and pause fuel-price-raising regulations.

California increased its gasoline tax to 63.4 cents per gallon on July 1, 2026 under the Road Repair and Accountability Act's annual inflation adjustment.

Within the lookback window, California's scheduled gas-tax increase still took effect. This is evidence that Valadao did not secure a halt to the state increase, though the commitment was framed as opposition/calling for action rather than direct enactment power.

SFGATE reported that a June 23 letter to Gov. Gavin Newsom from Rep. David Valadao and eight other California congressional Republicans criticized both taxes and California Air Resources Board actions tied to higher fuel costs.

Shows Valadao took concrete advocacy action against California fuel-cost increases after the campaign period. It supports delivery of the opposition/call component, but does not prove that California extended the diesel sales-tax exemption or stopped the tax increase.

Politico reported that Valadao touted support for increasing domestic energy production, suspending the gas tax increase, and opposing California climate programs linked by critics to higher gasoline prices.

During the relevant campaign cycle, Valadao publicly opposed the gas-tax increase and related California fuel regulations. This supports the promised advocacy stance, but it is not an official action delivering a statutory tax change.

California SB 1 increased fuel-related taxes, including a 12-cent gasoline tax increase, a 20-cent diesel excise tax increase, and an additional 4 percent sales and use tax on diesel fuel, while referencing exemptions under Revenue and Taxation Code Section 6357.3.

Official bill text establishes the state tax structure Valadao opposed and the diesel-tax framework connected to the exemption issue. It does not show Valadao could directly change state law from federal office.

AP reported that the California Air Resources Board approved Low Carbon Fuel Standard changes after political opposition, with critics warning of possible higher fuel prices.

Shows the California regulatory action Valadao and other Republicans opposed was not stopped. This supports a partial outcome: advocacy occurred, but the policy direction was not reversed.
