Fuel Prices in New Hampshire: What Drives the Pump
New Hampshire sits in the heart of New England, a corner of the country where fuel rarely arrives cheaply. As of the latest data, the state's average pump price for regular gasoline is $3.902 per gallon, with mid-grade at $4.509 and premium reaching $4.952. Diesel, the workhorse fuel for trucks and home heating logistics, sits highest of all at $5.206 per gallon. Those numbers run above the US national average of $3.867 for regular, putting the Granite State modestly on the pricey side of the ledger.
Why New Hampshire's Prices Look the Way They Do
The single biggest local lever on the price you see is tax. New Hampshire levies a state gasoline tax of about 22.2 cents per gallon, plus a 1.625-cent oil discharge and pollution control fee, on top of the federal excise tax of 18.4 cents. That combined burden is lighter than in many neighboring states, which helps explain why New Hampshire frequently undercuts Massachusetts, Vermont, and even nearby Maine at the pump. The state has no general sales tax, so unlike some jurisdictions there is no extra layer of sales-tax-on-fuel stacked on the per-gallon levy.
Geography and supply chains matter just as much. New Hampshire produces no crude oil of its own and has no refineries within its borders. Every gallon is imported, most of it moving up from terminals in the Boston and Portland areas or arriving via pipeline and barge into Portsmouth's harbor. That dependence on regional logistics means New England fuel prices tend to move together and to carry a freight premium compared with refining hubs along the Gulf Coast. When wholesale gasoline tightens in the Northeast, drivers in Concord and Manchester feel it quickly.
The Regional Picture and the Spread
The gap between regular and premium in New Hampshire is wide, roughly $1.05 per gallon, and the diesel premium over regular is steeper still at about $1.30. Diesel's elevated level reflects strong demand from freight and the overlap with heating-oil markets that dominate New England winters; the same distillate stream feeds both, so cold-weather heating demand can pull diesel prices up even when gasoline is calm.
Compared with low-tax, oil-producing states out west, New Hampshire's prices tell a different story. Drivers in New Mexico and Utah typically benefit from nearby production and shorter supply lines, while high-tax, import-dependent corridors such as New Jersey behave more like the Northeast. New Hampshire lands in between: a Northeastern importer, but one shielded somewhat by its low fuel tax and the absence of a sales tax.
The two metro areas tracked in the state show only modest internal variation, which is typical for a small, compact market served by the same handful of supply terminals. Without large interior distances, there is little of the rural-versus-urban price gap seen in bigger states.
FAQ
Why is gas more expensive in New Hampshire than the national average?
New Hampshire imports all of its fuel and sits at the end of New England supply lines, adding freight cost. While its state gas tax is relatively low and there is no sales tax on fuel, regional wholesale prices and distribution costs keep pump prices a bit above the US average of $3.867 for regular.
How much is the gas tax in New Hampshire?
The state charges roughly 22.2 cents per gallon plus a small oil discharge fee of about 1.6 cents, on top of the 18.4-cent federal excise tax. New Hampshire has no general sales tax, so no additional sales tax is layered onto fuel purchases.
Why is diesel so much higher than regular gasoline here?
At $5.206 per gallon, diesel runs well above regular. In New England, diesel shares a refining stream with heating oil, so winter heating demand can lift diesel prices. Strong freight demand and the region's import dependence add to the premium.
