Which vehicles are covered
The tax applies to a highway motor vehicle with a taxable gross weight of 55,000 pounds or more that is used on public highways during the tax period. Taxable gross weight is not the weight of the empty truck: it is the unloaded weight of the vehicle fully equipped for service, plus the unloaded weight of any trailers customarily used with it, plus the weight of the maximum load customarily carried.
That definition catches most combination tractors and a good number of straight trucks, and it is the reason a vehicle you think of as light can still be taxable.
The tax period is not the calendar year
The Form 2290 tax period runs from 1 July to 30 June. It is the single most common source of confusion on this form, because it means a return filed in August covers a period that started the previous month and ends the following summer.
A vehicle that was already in service on 1 July is reported for the full period. A vehicle first used later in the period is taxed only for the months remaining, which is why the month of first use is asked for on every vehicle rather than once on the return.
Weight categories
Vehicles are grouped into lettered categories by taxable gross weight, and the category sets the tax. Category A begins at 55,000 pounds and the bands step up from there; Category V covers vehicles over 75,000 pounds, which means 75,001 and above. A vehicle at exactly 75,000 pounds is Category U, not V, and getting that boundary wrong changes the tax due.
Category W is different in kind rather than in weight: it is the suspension category, described below.
A vehicle used for logging — transporting harvested forest products from the site — is taxed at a reduced rate within its weight category. It is a rate difference, not a separate category, and it has to be flagged on the vehicle.
Suspended vehicles: Category W
A vehicle you expect to run 5,000 miles or less during the period is suspended from the tax. The limit is 7,500 miles for agricultural vehicles. No tax is due on a suspended vehicle, but it is still reported and it still appears on your Schedule 1 — which matters, because the Schedule 1 is what proves to a DMV that the vehicle was declared.
If a suspended vehicle later exceeds its mileage limit, the tax becomes due for the entire period, not for the miles over the line, and an amended return is required.
What you need before filing
- An EIN. A Social Security number cannot be used on Form 2290, and a newly issued EIN can take a couple of weeks to become usable for e-filing.
- Your business name exactly as the IRS holds it against that EIN. A mismatch here is the single most common cause of rejection.
- The VIN of every vehicle, checked character by character against the title.
- The taxable gross weight of each vehicle, and its month of first use in the period.
- A 5-digit self-select PIN to sign with. Any five digits except 00000.
After it is filed
The IRS either accepts the return and returns a stamped Schedule 1, or rejects it with an error code. Acceptance is usually quick, but "usually" is not a guarantee and it is not something to rely on the day before a registration appointment.
A rejection is not a penalty and it is not a refiling fee at BKS. We read the code, correct the return and transmit it again.
