- UCR: next-year portal opens Oct 1; register and pay before Jan 1. 2027 carrier fees: 0-2 vehicles $55, 3-5 $167, 6-20 $333, 21-100 $1,163, 101-1,000 $5,548, 1,001+ $54,165.
- IFTA: quarterly returns due Apr 30, Jul 31, Oct 31, Jan 31.
- Form 2290: due Aug 31 for vehicles in use in July (55,000 lbs+); otherwise last day of month after first use.
