A Social Security number will not work
The IRS is explicit: you must have an EIN to file Form 2290 and you cannot use a Social Security number. This is true even for a sole proprietor with one truck and no employees, which is exactly the person most likely to assume otherwise.
An EIN is free from the IRS. There is no charge for obtaining one, and any service quoting a fee for the number itself is charging for the form-filling, not for the number.
A new EIN takes about four weeks to become usable
This is the single most important planning fact on this page. The IRS issues an EIN immediately through its online application, but it takes roughly four weeks for the number to be established across IRS systems — including the e-file database Form 2290 is validated against. Until then, an otherwise perfect return is rejected as a name and EIN mismatch.
It is often quicker than four weeks in practice, and it is sometimes not. Plan for four.
If you are forming a new company and buying a truck, apply for the EIN first, before the purchase completes. The registration timeline depends on it and nothing can compress it.
The name control has to match
The IRS holds a "name control" against each EIN — effectively the first four characters of the business name as registered. Your Form 2290 must carry the legal name that matches it. A trading name, an abbreviation or a slightly different punctuation will be rejected.
Your CP 575 EIN assignment letter is the authoritative record of what that name is. Keep it; you will need it more than once.
One EIN, one taxpayer
The return is filed by the person or entity responsible for the vehicle, under their own EIN. If you operate under your own authority, that is your EIN. If you own the truck and lease it to a carrier, the responsibility usually remains yours — the carrier’s EIN is not a substitute, and a Schedule 1 in somebody else’s name will not register your truck.
Where a leasing arrangement genuinely shifts the obligation, that is a question about the specific contract rather than a general rule, and it is worth asking before the deadline rather than after.
Changing the name or the entity
If the business name changes, the IRS record has to change before the return will validate against it. If the entity itself changes — a sole proprietorship incorporating, for instance — that is a new taxpayer with a new EIN, and the four-week clock starts again.
Neither of these is a Form 2290 problem as such, but both surface as a Form 2290 rejection, which is why they belong here.
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.
