Highway Use Fee by Filing Period

The Highway Use Fee is calculated based on an eligible motor vehicle’s weight and the number of miles driven in Connecticut. **Note that the filing and payment frequency was changed to quarterly, rather than monthly, starting with the calendar quarter commencing on October 1, 2023. **Data Disclaimer: Please note that the categorization of in-state and out-of-state taxpayers is based on the municipality reported on the tax return.

If no municipality was reported, the taxpayer will not be included in either the in-state or out-of-state column but will be included in the total taxpayer column.
