Massachusetts IFTA Rates & Trucking Overview 2026
Massachusetts at 24.0¢/gal is a relative bargain for New England — well below Connecticut (49.2¢), Rhode Island (34.0¢), and New Hampshire (22.2¢) is only slightly better. Boston is a top-10 US freight market and the economic hub of New England, generating enormous inbound consumer goods, food, and pharmaceutical freight.
The Mass Pike (I-90) is a toll road — EZ Pass or cash required at several plazas. Boston's dense street network makes final-mile delivery one of the most challenging in the US. Many carriers fuel at the large truck stops near I-495 in Wrentham or on I-90 near Palmer to maximize Massachusetts fuel before entering Connecticut or Rhode Island.
Massachusetts IFTA — Frequently Asked Questions
What is Massachusetts's IFTA diesel tax rate in 2026?
Massachusetts's diesel rate is 24.0¢/gal — low for New England. Connecticut at 49.2¢ and Rhode Island at 34.0¢ to the south and west are both significantly more expensive, making Massachusetts a smart fueling stop.
Who administers IFTA for Massachusetts-based carriers?
Massachusetts IFTA is administered by the Registry of Motor Vehicles (RMV). File quarterly at mass.gov/rmv. The Mass Pike (I-90) tolls are separate from IFTA and require E-ZPass or pay-by-plate billing.
What makes Boston challenging for commercial vehicles?
Boston's street grid predates the interstate system and has some of the tightest urban clearances in the US. The Storrow Drive restriction (10-foot height limit) is famous for catching rental trucks. Most commercial freight uses I-93, I-95, and I-495 to avoid urban core streets.
What freight sectors drive Massachusetts?
Life sciences and pharmaceutical distribution (Boston is a global biotech hub), retail and e-commerce to dense suburban markets, food and beverage for the New England restaurant industry, and construction materials for ongoing Greater Boston development.
