Estimated Connecticut HUF tax
$100.00
1,000 miles × 10¢/mile — the official rate for the 78,001 lbs–80,000 lbs bracket.
Estimate for one vehicle, one period, from the state's official published schedule. Filings also depend on exempt miles, method elections, and your assigned filing frequency — verify with the state before you file.
How the calculator works
Connecticut's Highway Use Fee (in effect since January 2023) applies to eligible vehicles with a gross weight of 26,000 lbs or more (Class 8–13). The rate ladder climbs from 2.5¢ per mile at the bottom to 10¢ at 80,000 lbs — and jumps to a flat 17.5¢ per mile over 80,000 lbs, which makes overweight-permit loads through Connecticut markedly more expensive than the same load one bracket down.
Unlike the quarterly weight-distance states, Connecticut files monthly through myconneCT. Registration, enforcement, and how HUF stacks with IFTA and NY HUT on a Northeast lane are covered in our Connecticut Highway Use Fee guide.

Frequently asked questions
How is the Connecticut Highway Use Fee calculated?
Connecticut miles multiplied by a per-mile rate that steps up with gross weight: from 2.5¢ per mile at 26,000 lbs to 10¢ at 78,001–80,000 lbs, and a flat 17.5¢ per mile for anything over 80,000 lbs. The full DRS schedule is on this page.
Who has to pay the CT Highway Use Fee?
Carriers operating eligible motor vehicles with a gross weight of 26,000 pounds or more (Class 8 through Class 13) on Connecticut public roads. You register for a Highway Use Fee permit with the Department of Revenue Services before operating, then file returns on your Connecticut miles.
How often is the CT Highway Use Fee filed?
Monthly — the return and payment are due the last day of the following month, filed electronically through the DRS myconneCT portal. A return is due even for months with no Connecticut miles while your permit is active.
Is anything exempt from the Connecticut Highway Use Fee?
The main statutory exemption is a motor vehicle carrying or transporting milk or dairy products to or from a dairy farm. There is no general exclusion for toll or turnpike miles — Connecticut has no truck tolls to exclude.
Is the CT Highway Use Fee the same as New York HUT?
Same idea — a per-mile tax bracketed by weight — but a separate program with its own registration, rates, and monthly (not quarterly) filing. A Northeast lane over 26,000 lbs commonly owes both: CT HUF for Connecticut miles and NY HUT for New York miles, on top of IFTA.
Is this the official DRS calculator?
No — it's a free estimator built on the DRS's official published per-mile schedule. Your actual return is filed through myconneCT and depends on your vehicle classification and any exempt operations.
