Rep. Willoughby Proposes Summer Gas Tax Suspension In Maricopa, Pinal Counties

Arizona House Majority Whip Julie Willoughby (R-LD13) has introduced legislation to temporarily suspend the state gasoline tax in Maricopa and Pinal counties during the summer months, citing higher fuel costs tied to air-quality regulations.

According to a release from the Arizona House Republican Caucus, Willoughby’s House Bill 2400 would suspend the state’s 18-cent-per-gallon gas tax on the special Cleaner Burning Gasoline blend required in Maricopa and Pinal counties from May through September.

“Because of federal requirements, families in Maricopa and Pinal counties are forced to pay more at the pump than the rest of Arizona,” Willoughby said in a statement. “During the summer, these counties can only sell Cleaner Burning Gasoline—a boutique fuel blend refined in limited quantities, primarily in California. That limited supply drives up costs, and Arizona drivers pay the price.”

“In 2023, Phoenix drivers paid higher gas prices than Los Angeles,” she continued. “As California refineries shut down, supply constraints will increase—pushing prices higher at a time when families are struggling with rising costs. Arizona now ranks as the sixth most expensive state in the nation for gas.”

Because of the added production and transportation costs, drivers in Maricopa and Pinal counties often pay more for gasoline than motorists elsewhere in Arizona, according to the House GOP. The release cited comparisons showing Phoenix-area gas prices exceeding those in Los Angeles during parts of 2023.

Willoughby said lawmakers have previously worked with federal officials to explore lower-cost fuel alternatives, but federal environmental requirements have limited available options. Her proposal includes a provision to backfill lost revenue to the Highway User Revenue Fund, which supports transportation infrastructure and is shared by state and local governments.

“Republicans are focused on affordability,” Willoughby said. “Our Majority Plan is about upholding the American Dream and making sure the cost of living doesn’t keep climbing out of reach for working families.”

In addition to the state tax suspension, Willoughby is advancing House Concurrent Memorial 2008, which urges Congress to suspend the federal gas tax on Cleaner Burning Gasoline during the same May-to-September period.
