Connecticut gas prices
Connecticut is one of the more expensive states for gas in the Northeast. High state taxes are the biggest factor. The state charges both a flat excise tax and a gross receipts tax on gasoline, which together push the per-gallon tax burden well above the national average.
The state has no refineries and imports all its fuel via pipeline and barge from the Gulf Coast and mid-Atlantic. Being at the end of the supply chain adds cost. Prices in Connecticut tend to track closely with Massachusetts and New York, though Connecticut often runs a few cents higher because of its tax structure.
Price history
Why is gas so expensive in Connecticut?
Connecticut has one of the highest combined gas tax rates in the country. The state charges both a flat excise tax and a percentage-based gross receipts tax. No local refinery capacity means all fuel is imported, adding transport costs on top.
How does Connecticut compare to other New England states?
Connecticut is usually the most expensive New England state for gas, slightly above Massachusetts and well above New Hampshire. New Hampshire benefits from having no sales tax and lower fuel taxes.
Does Connecticut have any fuel blend requirements?
Connecticut uses reformulated gasoline year-round in parts of the state to meet EPA air quality standards. This blend costs more to produce than conventional gasoline, adding a few cents per gallon.
