President Joe Biden says he’s mulling a potential pause on the federal gasoline tax.

The national price currently averages around $5 per gallon, and some observers worry that Americans are cruising to $6 gas by summer’s end.

“Yes, I’m considering it,” Biden told reporters in Delaware on Monday, when asked about a possible suspension of the 18.4-cents-per-gallon tax. “I hope to have a decision based on the data — I’m looking for by the end of the week,” he added.

National gas prices averaged $4.96 per gallon on Tuesday, according to AAA. California drivers were paying the most at $6.38 per gallon, while Georgia drivers were paying the least at $4.46, the data shows.

In April, taxes accounted for 12% of the cost in a gallon of gas, according to the U.S. Energy Information Administration. Crude oil was 60% of the price, the agency noted.

If the federal gas tax temporarily ceased, pickup truck drivers stood to save $5.52 every week, according to Patrick De Haan, head of petroleum analysis at GasBuddy. At the other end of the automotive spectrum, compact-car drivers would save $2.21.

In less than two weeks, AAA estimates a record-breaking 42 million people will hop in cars for Fourth of July travel. So what’s the chance for any price relief at the pump during a summer that’s estimated to be chock full of road trips?

States make efforts to reduce gas costs

Of course, the federal gas tax is levied in addition. to state-level taxes on gas. But some states have already taken matters into their own hands, and suspended their state gas taxes.

When Maryland paused its 36.1-cents-per-gallon tax from mid-March to mid-April, 72% of the tax savings were passed along to drivers in the form of lower costs, according to researchers at the Penn Wharton Budget Model. That came to a reduction of 26 cents per gallon for Maryland drivers.

During Georgia’s halt, between 58% and 65% of the tax savings were passed along to drivers. That translated to savings of between 18.8 cents per gallon and 16.8 cents per gallon. On Tuesday, the state boasted the country’s cheapest gas on average, according to AAA data.

The state imposes a tax of 29.1 cents per gallon on gasoline and 32.6 cents per gallon for diesel, and the estimated tax savings vary. The pause was set to run through May, but it’s now slated to end July 14.

Connecticut’s own 25-cent gas tax pause, which began on April 1, is scheduled to end after June 30. So far, drivers in the Nutmeg State have seen between 71% and 87% of the tax savings passed along, researchers said. That’s a range between 17.9 cents per gallon and 21.7 cents per gallon, the researchers said.

New York State’s gas tax pause through 2022 started this month, Florida’s break is scheduled for October, and legislators in more states are considering the idea.

The pauses on the gas tax — which typically go towards roads and infrastructure — are gaining some traction as gas prices keep increasing between consumer demand and the crude-oil price fallout from Russia’s invasion of Ukraine. That’s in the face of critics who have been wary of a tax pause with some panning it as a gimmick.

Biden could only apply the brakes on the federal gas tax with a Congressional law, according to Howard Gleckman, senior fellow at the Tax Policy Center. In February, some Congressional Democrats proposed a bill to put the tax on hiatus through the end of the year.

Gleckman said any gas tax break would be “a terrible idea” with dim odds for passage after Sen. Mitch McConnell, the Senate’s Republican minority leader, already dismissed the idea when it first emerged months ago. “If what you want to do is fight inflation, the last you want to do is increase demand for goods in short supply,” Gleckman said.

But the politics don’t neatly line up as the fight over gas tax breaks keeps playing out. In Virginia, for example, Democrats are against the tax break backed by Republicans.

“This seems less a matter of ideology,” Gleckman said, and more of “we’re just against what the other guy is proposing. It’s another variation of the politics of America in 2022.”
