Maryland gas prices typically run above the national average, influenced by above-average state taxes, reformulated fuel requirements across most of the state, and proximity to the high-cost Washington D.C. and Baltimore markets. The state occupies a middle position among East Coast states — more expensive than the Southeast but generally cheaper than New York, Pennsylvania, and New England. Maryland’s compact geography means price differences within the state are more modest than in larger states, though the D.C. suburbs consistently run above the statewide average.
Maryland’s state gas tax is approximately 47 cents per gallon — among the higher rates on the East Coast. The state restructured its fuel tax in 2013 to include a variable component tied to the Consumer Price Index, which means Maryland’s effective rate increases with inflation each year rather than requiring legislative action.
Maryland requires reformulated gasoline statewide — one of a relatively small number of states with a full statewide RFG mandate. The cleaner-burning but more expensive blend adds cost that applies uniformly across the state rather than just in specific metro areas.
Maryland receives fuel from multiple sources including pipeline connections to Gulf Coast supply and marine terminals along the Chesapeake Bay that serve the Baltimore market. The Washington D.C. suburbs in Montgomery and Prince George’s counties tend to run highest due to high operating costs and the influence of D.C. market pricing.
Did you know? Maryland is one of only a handful of states requiring reformulated gasoline statewide rather than just in specific metro areas, meaning every driver pays the premium for cleaner-burning fuel regardless of location. Maryland’s gas tax is automatically indexed to inflation under a 2013 law and has risen every year since. The Port of Baltimore is one of the most important fuel import terminals on the East Coast, handling significant volumes of refined petroleum products that supply Maryland and surrounding states.
