District of Columbia IFTA Calculator

The District of Columbia is unique among IFTA jurisdictions — it is not a state, has no interstates that terminate exclusively within its borders, and is surrounded by Virginia and Maryland on all sides (Maryland on three sides, with Virginia across the Potomac). Despite covering only 68 square miles, DC generates significant commercial vehicle activity from federal government logistics, the Georgetown and Southwest waterfront commercial zones, and the dense urban delivery demands of one of the most economically active metros in the country. I-95, I-66, I-295, and I-395 all converge in the DC metro area, with I-395 providing direct access to downtown DC from the Virginia side via the 14th Street Bridge.

DC's IFTA rate of $0.235 per gallon is lower than both its neighboring jurisdictions — Maryland at $0.369 and Virginia at $0.272. This means DC is actually one of the cheaper fueling options in the immediate area, though fuel stations capable of serving semi-trucks are extremely limited within the District itself. Most commercial vehicles fuel in Maryland (Beltway truck stops) or Virginia before entering DC.

Commercial vehicle access in DC is heavily restricted. The Metropolitan Police Department and DDOT enforce truck route regulations strictly — trucks over 10 tons are prohibited from most residential streets and are limited to designated commercial corridors. I-395 through the downtown core, New York Avenue (US-50), and the Southeast Freeway (I-695) are the primary commercial corridors. The 14th Street Bridge approach, the Theodore Roosevelt Bridge approach, and the Francis Scott Key Bridge into Georgetown each have weight and height restrictions that must be verified before approach.

For IFTA compliance, DC mileage is typically a small component of any quarterly return since most commercial vehicles pass through rather than operate exclusively within the district. However, because DC is a full IFTA member, DC miles and any fuel purchased in DC must be reported separately from Maryland and Virginia miles. The Office of Tax and Revenue handles DC IFTA administration and requires the same quarterly reporting format as any state.
