With fuel costs nonetheless excessive – averaging over US$4.50 a gallon in mid-Might 2026 – President Donald Trump mentioned he sought after Congress to droop the federal gasoline tax, which is eighteen.4 cents a gallon for fuel and 24.3 cents a gallon for diesel. A invoice has been presented within the Senate, and one is predicted to apply within the Area, in line with Politico, however their destiny is unclear.
States additionally fee their very own taxes, starting from 70.9 cents a gallon for gasoline in California to eight.95 cents in Alaska. Indiana, Georgia and Utah have suspended their gasoline taxes for a minimum of a few of 2026, and different states are taking into consideration identical measures.
As an power economist, I’ve observed how postponing the ones taxes does cut back costs, however now not up to politicians – or drivers – may hope. Analysis on previous gasoline tax vacations has discovered that buyers get about 79% of the relief in gasoline taxes. That implies oil firms and gasoline outlets stay about one-fifth of the tax reduce for themselves reasonably than passing that financial savings to the general public.
Postponing the federal gasoline tax, which will require Congress to go a regulation, wouldn’t assist customers a lot anyway. Although oil firms handed at the entire financial savings to customers, nationwide reasonable gasoline and diesel costs would drop simplest about 4%. The share relief in high-cost states reminiscent of California can be even smaller.
Gasoline taxes are only one a part of what drives gasoline costs. General, the cost of a retail gallon of gasoline is the sum of 4 issues: the price of crude oil, refining, distribution and advertising and marketing, and taxes.
In national figures from January 2026, crude oil accounted for roughly 51% of the pump value, refining kind of 20%, distribution and advertising and marketing about 11% and taxes about 18%. That blend shifts with stipulations: When crude oil costs spike, that may pressure greater than 60% of the associated fee; when the associated fee drops, taxes and logistics are better stocks of the fee.
Crude oil is the most important aspect
As a result of the cost of crude oil is the biggest component, many of the value on the pump is derived from the worldwide oil marketplace.
Typically, large swings in crude costs come basically from shifts in world call for and expectancies – now not from provide disruptions, in line with broadly cited analysis in 2009 through the economist Lutz Kilian.
However what is going on in early 2026 with the conflict in Iran is among the exceptions: a vintage provide surprise. Serious disruptions to transport throughout the Strait of Hormuz and assaults on Heart East oil infrastructure have taken hundreds of thousands of barrels a day without work the worldwide marketplace.
Maximum drivers normally can’t temporarily cut back how a lot they pressure or how a lot gasoline they use when costs upward push, so fuel call for doesn’t exchange a lot within the quick run. That implies a soar in crude prices has a tendency to lead to other folks paying extra reasonably than riding much less.
Refining, rules and the California puzzle
Refining turns crude into fuel at commercial scale. The U.S. doesn’t have a unmarried fuel marketplace, regardless that. Kind of 1 / 4 of U.S. fuel is a cleaner-burning mix of petroleum-derived chemical substances referred to as “reformulated gasoline,” which is needed in city spaces throughout 17 states and the District of Columbia to scale back smog.
California makes use of a fair stricter formula that few out-of-state refineries make. California could also be geographically remoted: No pipelines convey fuel in from different U.S. refining areas.
California’s fuel costs have longer term above the nationwide reasonable, defined partially through upper state taxes and stricter environmental regulations. However since a refinery hearth in Torrance, California, in 2015 lowered manufacturing capability, the state’s costs had been about 20 to 30 cents a gallon upper than what the ones elements would point out.
Power economist and College of California, Berkeley, professor Severin Borenstein has referred to as this the “mystery gasoline surcharge” and attributes it to the truth that there isn’t as a lot pageant between refineries or gasoline stations in California as in different states. California’s personal Department of Petroleum Marketplace Oversight says the surcharge charge the state’s drivers about $59 billion from 2015 to 2024. It’s now not precisely transparent who’s getting that cash, however it might be gasoline stations themselves or refineries, thru advanced contracts with gasoline stations.

Getting the gasoline into your automotive
The distribution and advertising and marketing class covers the prices of the entirety excited by getting the fuel from the refinery gate in your tank.
Fuel strikes through pipeline, send, rail and truck to wholesale terminals, after which through native supply truck to carrier stations.
On the store’s finish, the important thing elements are station hire and hard work, the fee to shop for fuel in bulk so as to promote it, bank card charges of up to 6 to ten cents a gallon at present costs, and franchise charges paid to the nationwide emblem, reminiscent of Sunoco or ExxonMobil, for permission to place their branding at the gasoline station.
Maximum gasoline station operators internet just a few cents consistent with gallon on gasoline itself – which is why many gasoline stations are actually comfort retail outlets with pumps out entrance. Borenstein and a few of his collaborators have additionally documented that retail gasoline costs upward push temporarily when wholesale prices climb however fall slowly when wholesale prices drop.
The query of gasoline tax vacations
Gasoline tax vacations cut back investment for what the taxes are designed to pay for, usually roads and bridges. That pushes street and bridge maintenance prices onto long term drivers and normal taxpayers.
There’s an extra downside, too: Taxes on fuel are meant to fee drivers for one of the most prices their riding imposes on everybody else – carbon emissions, native air air pollution, congestion and crashes. However Borenstein has discovered that U.S. gasoline tax ranges are already a ways beneath the real charge to society. Eliminating the tax on drivers successfully raises the prices for everybody else.
Postponing the Jones Act permits foreign-based oil tankers to sail between U.S. ports.

The Jones Act: A small quantity that provides up
The 1920 Jones Act is a federal regulation that calls for shipment transferring between U.S. ports to go back and forth on vessels constructed and registered within the U.S., owned through U.S. voters, and crewed basically through U.S. voters and everlasting citizens. Of the arena’s 7,500 oil tankers, simplest 54 meet this requirement. Handiest 43 of those can shipping subtle fuels reminiscent of fuel.
So, in spite of important refining capability at the Gulf Coast, some U.S. fuel is exported in another country even because the Northeast imports gasoline, partially reflecting the somewhat excessive charge of transferring gasoline between U.S. ports.
Economists Ryan Kellogg and Wealthy Sweeney estimate that the regulation raises East Coast fuel costs through a few penny and a part consistent with gallon on reasonable, costing drivers kind of $770 million a 12 months. In mild of the conflict’s impact on gasoline costs, the Trump management has quickly suspended the Jones Act necessities – an motion extra recurrently taken when hurricanes knock out Gulf Coast refineries and pipeline networks.
What strikes the quantity
The results of these kind of elements is that the associated fee that drivers see on the pump most commonly displays the worldwide value of crude, plus a stack of home prices, just a few of which can be inefficient.
Tax vacations give a partial, short-lived rebate. Jones Act waivers trim pennies, regardless that everlasting repeal would possibly purpose extra elementary adjustments, reminiscent of lowered rail and truck shipping of all items, which might decrease prices, emissions and infrastructure injury related to shipment transportation. Harmonizing gasoline blends throughout states and seasons would possibly decrease costs moderately, however most probably on the expense of higher emissions.
In the end, the most efficient coverage towards oil value shocks is a extra environment friendly gas-burning car, or one who doesn’t burn fuel in any respect. Within the interim, the most efficient I will be offering as an economist is readability about what that $4.50 in truth buys.
