The header: name, address and EIN
The business name must match what the IRS holds against your EIN — the name control. This is the single most common cause of rejection on the entire form, and it is decided before you reach any of the tax fields. Your CP 575 EIN assignment letter is the authoritative record of what that name is.
A Social Security number cannot be used here. A newly issued EIN takes about four weeks to become usable for e-filing.
The period code, and the boxes beside it
The form carries the month of first use as a six-digit code — 202609 for September 2026. Getting this wrong changes both the tax and the deadline, because the tax is prorated from this month and the return is due the last day of the following month.
Beside the address are the amendment boxes: Address Change, Amended Return, VIN Correction and Final Return. These are not interchangeable. An amended return reports additional tax becoming due; a VIN correction fixes a character on an already-filed return and carries no tax; a final return says you will not file again.
The first-use month is the month the vehicle was first driven on a public highway during this period — not the month it was bought, delivered or titled.
Part I, lines 1 to 6
Line 2 is where the weight categories do their work. Each vehicle sits in a lettered category by taxable gross weight, and a vehicle first used after July is taxed for the months remaining rather than the full year.
Line 5 is the one most often left blank when it should not be. A truck sold, destroyed or stolen during the period generates a credit for the unused months, and it is claimed here rather than being lost.
| Line | What it is |
|---|---|
| 1 | The month of first use, as the period code above. |
| 2 | The tax, from the Tax Computation table on page 2, totalled across every vehicle. |
| 3 | Additional tax from an increase in taxable gross weight, on an amended return. |
| 4 | Total tax: line 2 plus line 3. |
| 5 | Credits for vehicles sold, destroyed, stolen, or used under the mileage limit. |
| 6 | Balance due: line 4 less line 5. |
Part II: the suspension statements
This is where you declare vehicles expected to run 5,000 miles or less during the period — 7,500 for agricultural vehicles — which are suspended from the tax and reported in category W. You also report here any vehicle suspended on a previous return that was later sold, and any suspended vehicle that exceeded its mileage limit.
A suspended vehicle still appears on the Schedule 1. That is the point of declaring it.
Schedule 1: the vehicle listing
Schedule 1 lists every VIN on the return with its category letter. Check each VIN character by character against the title rather than the bill of sale — the two disagree more often than you would expect, and a VIN that does not match the title will fail at registration even though the IRS accepted it.
The stamped copy the IRS returns after accepting the return is the document a DMV asks for. It is the whole output of this exercise.
Third party designee, signature and PIN
The third party designee section lets you authorise someone — an accountant, a filing service — to discuss the return with the IRS. It is optional and it is not the same as authorising them to sign.
The taxpayer signs with a five-digit self-select PIN, any five digits except 00000. Federal law requires the taxpayer’s signature; a preparer cannot supply it on their behalf.
What filing electronically changes
Electronically, you are not filling in boxes — you enter the vehicles and the software computes lines 2 through 6, assigns the category letters and builds the Schedule 1. Electronic filing is required for any return reporting 25 or more taxed vehicles, and is the only route that returns a stamped Schedule 1 in minutes rather than weeks.
The three fields that matter are still the three named at the top of this page, because those are the ones no software can check for you: the first-use month, the taxable gross weight, and the business name.
This guide explains how Form 2290 works in general terms. It is not tax advice for your business, and the IRS is the authority on the rules themselves. See About Form 2290 at irs.gov. For your situation, talk to the practice.
