Connecticut Gas Prices This Week

In the EIA’s July 2026 (revised August 2026) table of motor fuel taxes, Connecticut’s state taxes and fees on gasoline total 25.0¢ a gallon, tied for the 15th-lowest of the 50 states and D.C. The 51-jurisdiction average is 33.8¢, and the federal tax adds 18.4¢ everywhere. The per-gallon excise tax is 25¢. Connecticut also levies a petroleum products gross earnings tax of 8.1 percent on the first sale of petroleum products in the state, which the EIA lists separately. In 2022 the state suspended the 25¢ excise from April 1 through December 31, then restored it in 5¢ monthly steps, reaching the full rate again on May 1, 2023.

Connecticut has no refineries. Like the rest of New England, it is supplied mainly by tanker and barge, and New Haven Harbor is the state’s main fuel-receiving port. The EPA places every Connecticut county in a federal reformulated-gasoline area: most of the state in the Greater Connecticut area and Fairfield County in the New York metro area.

The EIA publishes only an annual average for Connecticut. In that series the state has been one of the more expensive places to buy gasoline for decades. It ranked 47th-cheapest of 51 in 1990, 49th in 2000, and 42nd in 2024. Its average gap to the U.S. figure was 18.8¢ above in the 1990s, 9.7¢ above in the 2000s, 14.1¢ above in the 2010s, and 9.0¢ above in 2020–2024. The highest annual average is $4.07, in 2022, 17.3¢ above the U.S. average; adjusted for inflation, the peak was 2012, at $5.30 in 2025 dollars. The largest one-year declines came in 2015 (29.3%) and 2009 (26.7%), and the largest increase since 2000 in 2021 (35.9%).

Connecticut has no weekly EIA series, so its seasonal pattern is best read from the EIA’s weekly New England region (PADD 1A). Averaged over 2004–2025, New England prices are 7.7% below the year’s average in January and 6.1% above in June, and April is still slightly below average (0.5%), later than the spring rise farther south.

Connecticut averaged below the U.S. figure in 4 of 55 years from 1970 to 2024: 1975–1977 and 1982. It averaged 1.1¢ below in 1982, the largest amount below in any year, and that year also gave it the cheapest ranking it has held, 14th-cheapest. In the other 51 of 55 years it averaged above, and the largest amount above was 26.3¢ in 1997.

The least favourable ranking was 50th-cheapest, or 2nd-most-expensive, in 1988, 1995 and 1996. At the start of the series Connecticut was 40th-cheapest in 1970 at $0.37. It was 41st-cheapest in 1980 at $1.26, the year its average rose 39.1%, the largest one-year rise in the series. The 2010 average was $2.86, ranked 43rd-cheapest, and the 2020 average was $2.22, ranked 35th-cheapest (tied).

Among its bordering states in 2024, Massachusetts averaged $3.33, Rhode Island $3.34 and New York $3.17. Connecticut's $3.37 was 3.9¢ above Massachusetts, 2.9¢ above Rhode Island and 20.0¢ above New York, while the U.S. average was $3.29. In constant 2025 dollars the 2024 figure is $3.46, and the lowest in the series was $2.47 in 1998.
