Maryland IFTA Rates & Trucking Overview 2026

Maryland's diesel rate of 36.9¢/gal (indexed to CPI) is above average and significantly higher than neighboring Delaware (22.0¢). Baltimore is one of the top 10 US ports by cargo volume and a major auto import terminal. The I-95 corridor through Baltimore's Fort McHenry Tunnel is a critical Northeast freight bottleneck — tunnel tolls add to operating costs.

Major Maryland Trucking Routes

I-95 (Baltimore–DC–Virginia, Northeast Corridor), I-70 (Baltimore–Frederick–Hagerstown–West Virginia), I-83 (Baltimore–Pennsylvania), I-81 (Hagerstown–Pennsylvania/Virginia), I-68 (Cumberland–West Virginia)

Delaware to the east offers 22.0¢ diesel — that's nearly 15¢ cheaper per gallon. Drivers on I-95 northbound should maximize fuel loads before crossing from Virginia (27.5¢) into Maryland, and again in Delaware before re-entering Maryland from the north. West Virginia to the west at 35.7¢ is nearly equal, so no significant savings crossing that border.

Maryland IFTA — Frequently Asked Questions

What is Maryland's IFTA diesel tax rate in 2026?
Maryland's IFTA diesel rate is approximately 36.9¢/gal for 2026. The rate is indexed annually to CPI. Delaware at 22.0¢ is the dramatically better fueling choice for I-95 corridor drivers — the largest rate differential on the eastern seaboard within adjacent states.
Who administers IFTA for Maryland-based carriers?
Maryland IFTA is handled by the Motor Vehicle Administration (MVA). File quarterly at mva.maryland.gov. Maryland also has a vehicle weight fee structure for heavy commercial vehicles.
Does Baltimore's Fort McHenry Tunnel restrict certain cargo?
Yes. The Fort McHenry and Baltimore Harbor tunnels prohibit hazardous materials. Hazmat loads must use the I-695 beltway around Baltimore. This adds significant mileage for tankers and other hazmat carriers on the Northeast Corridor.
What are Maryland's major freight markets?
Baltimore port (autos, coal, sugar, forest products) is the #1 freight generator. The I-270 Tech Corridor generates significant high-value freight. Distribution centers along I-95 in the Baltimore–DC metro serve the dense Mid-Atlantic consumer market.
