How the tax works

The road toll, raised once since 1991

New Hampshire calls its gas tax the road toll. It is a flat 22.2¢ a gallon. The rate was 18 cents from 1991 until July 1, 2014, when Senate Bill 367 added 4.2 cents to pay for widening Interstate 93 and other road and bridge work. That increase is temporary in law: it is set to end once the I-93 bonds are repaid, or in 2034 at the latest. The road toll is not indexed.

The rest of the state figure is two environmental fees. The larger, for the Oil Discharge and Disposal Cleanup Fund, is about 1.3 cents a gallon on gasoline and diesel. A smaller Oil Pollution Control Fund fee applies to most petroleum products. New Hampshire has no general sales tax, and the EIA does not flag it for local option fuel taxes.

In the EIA’s July 2026 (revised August 2026) table, New Hampshire’s total of 23.7¢ is the 10th-lowest of the 50 states and D.C. The 51-jurisdiction average is 33.8¢. For New Hampshire pump prices, see New Hampshire gas prices.

Where New Hampshire Sits Among Its Neighbors

Maine, at 31.5¢ in the EIA's July 2026 table, has the highest state total among the 3 states that border New Hampshire. Vermont follows at 31.3¢ (EIA table, July 2026), and Massachusetts has the lowest at 27.6¢. New Hampshire's 23.7¢ (EIA table, July 2026) is 7.7¢ below Maine, 7.5¢ below Vermont and 3.8¢ below Massachusetts.

Within the same July 2026 table, the 10th-lowest rank puts 9 jurisdictions under New Hampshire's total and 41 above it. The 50 states and D.C. average 33.8¢ (EIA table, July 2026), and New Hampshire's total is 10.0¢ below that average. Alaska holds the low end at 9.0¢ (EIA table, July 2026), while California holds the high end at 73.6¢.

The split inside the New Hampshire figure is 22.2¢ (EIA table, July 2026) of excise and 1.5¢ of other state taxes and fees, so excise is 93% of the state total. Adding the federal 18.4¢ (EIA table, July 2026) gives 42.1¢, and the state's share of that combined amount is 56%.

The EIA's July 2026 table covers state taxes of general application and leaves out county and local taxes. It lists no local option gasoline taxes for New Hampshire, so the 23.7¢ (EIA table, July 2026) and the neighbor comparisons above rest on state-level figures only.
