Form 2290 divides vehicles into 9 categories depending on their type and weight. They are qualified farm vehicles, highway motor vehicles, buses, log-based vehicles, state-apportioned vehicles, anti-theft devices or qualified private vehicles. The category of vehicle you fall into will determine how much you will owe in taxes and how often you need to file. If you are unsure of which category your vehicle falls in, our customer support representatives are happy to advise you on the best way to fulfill your filing requirements.
