When you buy a used heavy truck and register it in your name, you have your own Form 2290 to file. The seller's stamped Schedule 1 is the seller's proof of payment, not yours.
When your return is due
Like any truck: by the last day of the month after the month you first use it on a public highway during the period. Driving it home from the seller counts as use. Check the date with the Form 2290 due date calculator.
If the seller already paid this period
The IRS has a special rule for a used truck bought from a seller who already paid the tax for the current period. If you buy it on or after July 1, 2026 but before June 1, 2027, and your first use is in the month of the sale, your tax doesn't include the month of the sale. It's prorated from the first day of the next month to the end of the period.
The IRS's own example, using a category V truck (over 75,000 pounds):
| Step | Detail |
|---|---|
| Seller paid the full period on July 2, 2026 | $550.00 |
| Buyer purchases September 9, drives it home the next day | First use in the month of sale |
| Buyer's tax: October through June | 9/12 of $550 = $412.50 |
| Month entered on line 1 | October 2026 ("202610") |
| Buyer's due date | October 31 is a Saturday, so November 2, 2026 |
Note the due date doesn't move just because you enter the following month on line 1 — it is still based on when you actually first used the truck.
To use this rule you must:
- Determine that the seller paid the tax for the current period. A copy of the seller's stamped Schedule 1 is one way.
- Enter the month after the sale as the month on line 1.
- Enter the prorated tax for the rest of the period.
The seller, meanwhile, can claim back the tax for the months after the sale — see the credit for a sold truck. If the seller didn't pay this period, your tax is simply figured from the month you first used the truck — run it through the Form 2290 tax calculator.
If the truck was suspended when you bought it
If the seller reported the truck as suspended (expected to run 5,000 miles or less, or 7,500 for agricultural vehicles), the seller must give you a statement showing:
- The seller's name, address, and EIN.
- The VIN.
- The date of the sale.
- The odometer reading at the beginning of the period and at the time of sale.
- Your name, address, and EIN.
You attach that statement to your Form 2290 and file by the normal deadline. The mileage limit counts the truck's total highway miles for the period, including the previous owner's. If it goes over after the sale and you received the statement, the tax is yours; if the seller never gave you one, the seller is also liable. See suspended vehicles and category W.
Registering the truck
The IRS says no proof of payment is required for a vehicle bought within the last 60 days if you show the state a copy of the bill of sale. You still have to file and pay by the deadline.
Keep this in your records
When you acquire a used taxable truck, keep proof of whether it was used, or the tax suspended, before it was registered in your name. A written statement signed and dated by the seller or dealer works. Keep it with the purchase date and the seller's name and address for at least 3 years.
