Gas prices in Washington, DC

About gas prices in Washington, DC

Washington DC sits in PADD 1B Northeast with no in-area refining capacity. Pipeline access via Colonial Pipeline plus tanker imports through Port of Baltimore and Port of Hampton Roads keep supply stable. DC has no state-level gas tax but applies a local fuel tax of around 24 cents per gallon. Reformulated gasoline is required through summer ozone season. Pricing typically runs 15 to 25 cents above the national average. Drivers across the metro see meaningful pricing variation: stations in Maryland suburbs (Bethesda, Silver Spring, Rockville) and Virginia suburbs (Arlington, Falls Church, Alexandria) often run 10 to 20 cents below DC city stations due to different state tax structures. Costco locations in Arlington, Pentagon City, and along the I-95 corridor post the lowest pricing.
