Delaware gas prices typically run near the national average with a slight tendency to run modestly below it — a somewhat surprising outcome for a small Mid-Atlantic state surrounded by higher-price neighbors. Delaware has no general sales tax — a distinction that attracts shoppers from across the region — and its fuel tax is moderate. The state’s position along the I-95 corridor generates significant interstate traveler fuel demand that supports a competitive retail market, and Delaware’s proximity to Philadelphia area refinery and terminal infrastructure provides reasonable supply access.
Delaware’s state gas tax is approximately 23 cents per gallon, below the national average. The state does not apply general sales tax to gasoline — consistent with its broader no-sales-tax policy — keeping the total effective burden lower than neighboring Maryland, Pennsylvania, and New Jersey.
Delaware benefits from proximity to fuel terminal infrastructure in the Philadelphia area and along the Delaware River corridor, providing good supply access at competitive wholesale prices. The state’s position directly on the I-95 corridor generates high-volume interstate traffic that creates competitive pressure among fuel retailers serving both local and through-traffic customers.
Delaware is small enough that there is minimal intrastate price variation — Wilmington in the north and Rehoboth Beach in the south are only about 100 miles apart, and supply infrastructure covers the entire state without significant remote delivery premiums.
Did you know? Delaware is the only Mid-Atlantic state with no general sales tax — a policy that has made it a shopping destination for residents of neighboring Maryland, Pennsylvania, and New Jersey, and contributes to fuel prices modestly more affordable than its immediate neighbors. More corporations are incorporated in Delaware than in any other state — over 60 percent of Fortune 500 companies are Delaware corporations — generating significant Wilmington economic activity despite the state’s tiny size. Stations near the Delaware Memorial Bridge on the Delaware side compete aggressively for travelers who know they can fill up more cheaply in Delaware than in New Jersey or Maryland.
