Connecticut Highway Use Fee help
Connecticut’s Highway Use Fee applies to carriers operating eligible heavy multi-unit motor vehicles on Connecticut highways. Covered carriers register through myconneCT, report the qualifying vehicle miles for each quarterly period, and file even for a zero-activity quarter while the account remains active.
Review eligibility by vehicle, not only carrier size
Connecticut’s current rule considers gross weight and multi-unit FHWA vehicle classification. Review each vehicle and the actual Connecticut operation.
Maintain Connecticut miles by eligible vehicle
The fee uses vehicle weight and Connecticut miles. Keep unit, classification, weight, route, and distance evidence that reconciles with IFTA, dispatch, ELD/GPS, toll, and other trip records.
- myconneCT account and HUF registration
- Eligible vehicle inventory and classification

The account remains active until properly changed
Continue filing the required returns, including zero activity, until DRS confirms the account is closed or no longer requires returns.
What Mann does—and what the agency decides
Mann Registration can help collect facts, prepare filings, organize records, and track follow-up. Mann is an independent private service provider, not Connecticut Department of Revenue Services, and cannot approve an application, change an agency record without the required process, give legal or tax advice, or guarantee timing or results.
