You must have an Employer Identification Number to file Form 2290. You cannot use your Social Security number — not as a sole proprietor, not as a single-truck owner-operator, not in any circumstance.
The IRS lists the EIN first among the three things you need before completing the form, alongside each vehicle’s VIN and taxable gross weight. From the Instructions for Form 2290 (Rev. July 2026).
How do I get an EIN?
Apply online at IRS.gov/EIN. It’s free and there’s no reason to pay a third party for it.
Two alternatives exist. If you have an address in a foreign country — Canada, for example — you may apply by calling 267-941-1099, which is not a toll-free number. You can also apply by faxing or mailing Form SS-4, Application for Employer Identification Number.
I’m a sole proprietor with one truck. Really?
Really. The requirement isn’t about business size or structure — Form 2290 is a federal excise tax return, and the IRS requires an EIN on it regardless of whether you have employees or operate as an individual.
This surprises a lot of first-time filers who’ve spent years reporting business income under an SSN on Schedule C. Income tax and excise tax have different identification requirements.
What about LLCs and disregarded entities?
This is where filers get it wrong most often. Qualified subchapter S subsidiaries (QSubs) and eligible single-owner disregarded entities are treated as separate entities for most excise tax and reporting purposes.
They must pay and report excise taxes, register for excise tax activities, and claim any refunds, credits, and payments under the entity’s own EIN. These actions cannot take place under the owner’s taxpayer identification number.
So if your truck is registered to a single-member LLC, that LLC needs its own EIN for Form 2290 — even though the same LLC is disregarded for income tax purposes. Some QSubs and disregarded entities already have one. If you’re unsure, the IRS Business and Specialty Tax line is 800-829-4933.
Why do new EINs cause rejections?
This part comes from e-filing practice rather than the IRS instructions, so treat it accordingly.
When you e-file, the IRS validates your EIN against the business name associated with it in IRS records. A newly issued EIN generally needs time to propagate into the e-file system. Submit before that happens and the return comes back rejected on a name/EIN mismatch — not because your EIN is invalid, but because the validation database hasn’t caught up.
The practical guidance filers are commonly given is to wait before e-filing with a brand-new EIN. If you know you’ll need to file, apply well ahead of your deadline rather than the week of.
Getting the business name right
The name you file under must match IRS records for that EIN. Common mismatches that trigger rejection:
- Filing under a DBA or trade name when the EIN is registered to a legal entity name
- Adding or dropping “LLC,” “Inc.,” or punctuation that differs from the registration
- Using a personal name when the EIN belongs to a company, or the reverse
- Abbreviations that don’t appear in the IRS record
Your name and address on Schedule 1 must also match Form 2290 page 1 exactly, and the EIN must be the same on both.
Frequently asked questions
Can I use my old employer’s EIN?
No. The EIN must belong to the person or entity the vehicle is registered to.
I have two businesses. Which EIN?
The one belonging to whoever the truck is registered to. Filing obligation follows registration.
Does an EIN cost money?
No. It’s free from the IRS. Services charging for it are reselling a free government process.
My return was rejected for EIN mismatch. Now what?
Confirm the exact business name on record for that EIN, correct the entry, and resubmit. If the EIN is newly issued, the delay itself may be the cause. See e-filing.
