This rate is reported on your quarterly IFTA return and net taxes owed or credited are calculated based on miles driven vs. fuel purchased in each jurisdiction.

Vermont participates in IRP; registration through VT DMV. No separate state motor carrier permit; UCR registration required. Your IRP registration covers operating in Vermont as long as it is listed on your cab card. If Vermont is not on your cab card, you will need a temporary trip permit: $25 for temporary trip permit.
