The month that matters is first use, not purchase
The deadline runs from the month the vehicle was first used on a public highway during the tax period — not the month you bought it, not the month it was delivered, and not the month it was titled. A truck bought on 20 September and left on the lot until 3 October is an October first-use vehicle.
The return is then due the last day of the month following first use. For an October truck, that is 30 November.
This is the rule that produces most late mid-year returns. The purchase feels like the event; the IRS cares about the first highway mile.
You pay for the months remaining, not the year
The tax is prorated over the months left in the period, counting the month of first use. A vehicle first used in November is taxed for eight of twelve months, so a Category V tractor pays $366.67 rather than $550. A vehicle first used in March pays four twelfths.
The proration is by month, not by day. A truck first used on 28 November is taxed the same as one first used on 2 November.

| July (or already in service) | 12 of 12 |

| October | 9 of 12 |
| November | 8 of 12 |
| December | 7 of 12 |

| March | 4 of 12 |
| April | 3 of 12 |

The seller’s Schedule 1 does not transfer
The Heavy Vehicle Use Tax follows the user, not the vehicle. The previous owner’s stamped Schedule 1 proves that they paid for their months; it proves nothing about yours, and a DMV will not accept it for your registration.
The seller may be entitled to a credit for the unused months on their own next return, or a refund on Form 8849. That is their claim, not a discount on yours.
What you need before you can file
- Your own EIN, established with the IRS for at least about four weeks.
- The business name exactly as the IRS holds it against that EIN.
- The VIN, checked character by character against the title rather than the bill of sale.
- The taxable gross weight: the truck fully equipped, plus trailers customarily used with it, plus the maximum load customarily carried.
- The month you first drove it on a public highway.
If the truck will hardly be driven
A vehicle you expect to run 5,000 miles or less during the remainder of the period is suspended and owes no tax — 7,500 miles for an agricultural vehicle. It still has to be reported and it still appears on the Schedule 1, which is what registration depends on.
Be realistic about the estimate. If it goes over the limit, the tax becomes due for the whole period and an amended return follows.
