> Added a truck after filing Form 2290? File a new 2290 with only the new VINs by the last day of the month after first use - prorated tax, its own Schedule 1.

## TL;DR

> You cannot add a truck to a Form 2290 you already filed. The IRS says to file a new Form 2290 listing only the new vehicles, due the last day of the month after you first drive the truck on a public highway. The tax is prorated from that first-use month through June 30, and the IRS returns a second stamped Schedule 1 covering the added VINs.

## Key takeaways

- An added truck gets its own new Form 2290 listing only the new VINs - not an amendment.
- Due the last day of the month after first use: an October first use is due November 30.
- Tax is prorated: annual category rate times the months from first use through June, divided by 12.
- You end up with two stamped Schedule 1s for the period; keep both for the plate office.
- Trucks first used in different months need separate returns, one per first-use month.

## FAQ

### Can I add a vehicle to my existing Form 2290?

No. The IRS says that if you e-file Form 2290 and later buy one or more additional vehicles, you must file a new Form 2290 listing only the new vehicles. The Amended Return box is reserved for a weight increase or a suspended vehicle that exceeded the mileage limit, and the VIN Correction box only fixes a typo, so an added truck always means a fresh return under the same EIN.

### When is Form 2290 due for a truck I added mid-year?

By the last day of the month following the month you first used the truck on a public highway. A truck first used in October 2026 is due November 30, 2026; a December 2026 first use is due February 1, 2027 because January 31 falls on a Sunday. First use means the first time it runs on a public road during the period, not the purchase date, and a weekend or holiday deadline moves to the next business day.

### How much HVUT do I owe on a truck added mid-year?

A prorated share of the annual amount for its weight category: the annual rate times the number of months from the first-use month through June, divided by 12. A Category V truck (over 75,000 lbs, $550 a year) first used in October owes 9/12 of $550, or $412.50. A truck bought used from a private seller uses the month after the sale, and a truck expected to run 5,000 miles or less is listed as suspended at $0.

### Do I check the Amended Return box when adding a truck?

No. Leave both the Amended Return and VIN Correction boxes blank. The instructions say to check Amended Return only for additional tax from an increase in taxable gross weight or for suspended vehicles that exceeded the mileage limit, and to check VIN Correction only when fixing a VIN on a previously filed Schedule 1. An added vehicle is an ordinary original return with a later first-use month.

### Will I get a second stamped Schedule 1 for the added truck?

Yes. Each Form 2290 produces its own stamped Schedule 1 listing only the VINs on that return, so after adding a truck you hold two Schedule 1s for the same tax period. Give the plate office the one that shows the truck being registered - the July annual Schedule 1 does not cover the added VIN. Keep every Schedule 1 for the period with your records for at least three years.

### What if I add two trucks in different months?

File a separate Form 2290 for each first-use month. The IRS is explicit that two vehicles first used in two consecutive months cannot share one return, because the tax on each depends on its own first-use month; you file two Forms 2290 and complete a Schedule 1 for each. Trucks first used in the same month can go on one return together.
