Start E-FilingWestern Star builds heavy, purpose built trucks for long haul and vocational work, and like any Class 8 truck they file the Heavy Vehicle Use Tax. Whether you run a highway tractor or a heavy vocational rig, filing is quick once you know your weight category.
Does a Western Star file Form 2290?
Yes. A Western Star tractor pulling a loaded trailer, or a heavy vocational Western Star, sits well above the 55,000 pound threshold, so it files Form 2290 for each period it runs on public highways. These trucks are built to run heavy, which usually puts them in the top weight categories.
Finding your weight category
Your tax is set by taxable gross weight: the truck fully equipped, the trailer it customarily pulls, and the heaviest load. A loaded Western Star combination generally reaches the highest IRS weight category and its full annual rate. Enter your real running weight in the finder below to lock in the exact category.
Western Star's current models file the same way. The 49X is built for heavy vocational and on highway work, and the 47X handles medium and heavy vocational duty. Both are heavy enough to reach the upper weight categories once loaded, so run your real numbers through the finder to pin down the exact one.
What to have ready
- An active EIN matched to your legal business name.
- Your Western Star VIN.
- Your taxable gross weight category.
- The first used month for this period.
