Buying or Selling a Used Truck: Form 2290 Rules That Catch People Out

A used-truck sale mid-year creates 2290 obligations on both sides of the deal — and the rules aren't what most people assume.
If you're the buyer
Your Form 2290 clock starts at your first use of the truck on a public highway:
- Deadline: the last day of the month after your first-use month. Buy and first run it in October 2026 → file by November 30, 2026.
- Tax: prorated for the months remaining in the period (October first use ≈ 9/12 of the annual amount).
- The seller's Schedule 1 does not transfer. Your state wants a Schedule 1 in your name to register the truck — this is the single most common surprise.
One wrinkle: if the seller already paid the full year's tax on that truck, the IRS provides a special computation that can reduce the buyer's tax — worth checking when buying from a carrier mid-period.
If you're the seller
You don't lose the tax you prepaid:
- Claim a prorated credit for the months after the sale — either as a credit line on your next Form 2290, or as a refund via Form 8849 (Schedule 6).
- Keep a record of the sale: buyer's name and address, VIN, and sale date.
- If the truck was suspended (Category W), give the buyer a written statement of the suspension — otherwise liability for crossing the mileage limit can land on you.
The paperwork checklist for a clean handoff
- Bill of sale with the exact VIN and date
- Seller: file the credit/refund claim; don't just forget the money
- Buyer: file your own 2290 by the month-after deadline; bring your new Schedule 1 to the DMV
- Both: keep copies for three years
What about dealer purchases?
Same rules — the dealer isn't filing 2290 for you. Your first highway use starts your deadline, whether the truck came from an auction, a dealer, or a private sale.
