Hawaii Gas Tax
Hawaii’s state taxes and fees on gasoline total 18.5¢ a gallon, the 2nd-lowest of 51; with the 18.4¢ federal tax, drivers pay 36.9¢ a gallon in combined tax. Rates are from U.S. Energy Information Administration data as of July 2026.
What makes up Hawaii’s 36.9¢
| Hawaii state excise tax | 16.0¢ |
|---|---|
| Other Hawaii taxes & fees sales/use taxes, inspection and environmental fees | 2.5¢ |
| Total Hawaii state tax | 18.5¢ |
| Federal excise + LUST fee 18.3¢ excise + 0.1¢ LUST, unchanged since 1993 | 18.4¢ |
| Combined state + federal | 36.9¢ |
In addition to State rates: Honolulu: $0.1650/gal; Maui: $0.2400/gal; Hawaii: $0.2300/gal; Kauai: $0.1700/gal. Environmental Response, Energy, and Food Security Tax $0.0250/gal.
Hawaii's tax: a low state rate and county fuel taxes
Hawaii’s state fuel tax on highway gasoline is 16.0¢ a gallon, set by the legislature, and the state adds an environmental response, energy, and food security tax of $1.05 a barrel, about 2.5¢ a gallon. Those two make up the EIA figure.
The larger share of the tax on a gallon in Hawaii is local. Each county sets its own fuel tax by ordinance: in the EIA’s current table, 16.5¢ in Honolulu, 24¢ in Maui County, 23¢ in Hawaii County, and 17¢ on Kauai. In every county the county tax is at least as large as the state rate. Retail gasoline sales are also subject to the state’s general excise tax, although the fuel taxes themselves are deducted from the amount the general excise tax is charged on.
Counting state taxes only, Hawaii’s 18.5¢ a gallon is the 2nd-lowest of the 50 states and D.C., against a 51-jurisdiction average of 33.8¢, so the ranking understates what drivers pay once county and general excise taxes are included.
How the tax fits with fuel supply and price history is covered on the Hawaii gas prices page.

Local option taxes on gasoline also apply in parts of Hawaii. They are not part of the 18.5¢ total or of the 2nd-lowest rank in the EIA's July 2026 table, which covers state taxes of general application.
