New Hampshire IFTA Rates & Trucking Overview 2026
New Hampshire at 22.2¢/gal is the cheapest diesel in New England — significantly lower than Massachusetts (24.0¢), Maine (31.2¢), Vermont (32.0¢), and dramatically cheaper than Connecticut (49.2¢). NH has no sales tax, which further reduces pump prices vs. neighboring states. The state is small but its position on I-93 between Boston and Vermont/Canada makes it a strategic fuel stop.
Manchester and Nashua in southern New Hampshire have grown into regional distribution centers serving the Boston metro's northern suburbs. The Portsmouth area on I-95 is a gateway to Maine. Most drivers on the I-93 corridor top off in New Hampshire before heading south into Massachusetts or north into Vermont. The White Mountains require careful weight consideration on US-302 and NH-16.
