An EIN is your LLC’s federal tax ID. Getting one is free, fast, and takes about ten minutes on the IRS website. Here’s exactly what you need to know — plus what we do for you when we file on your behalf.
Think of it as a Social Security Number, but for your business.
An EIN — short for Employer Identification Number — is a nine-digit ID the IRS issues to businesses. It’s how the federal government (and basically every bank, payroll service, and vendor) tells one business apart from another. The name is a little misleading: you don’t need employees to get one. Most single-member LLCs grab an EIN the same week they form, because without it you can’t open a business bank account or file business taxes cleanly.
You only get one EIN per entity, and it doesn’t expire. If you dissolve the LLC, the EIN is retired — not reassigned.
The IRS gives EINs out for free. Anyone charging you $75+ to “register” one is reselling something you can get in ten minutes.
The fastest route is the IRS’s online EIN Assistant at irs.gov/ein. It’s available weekdays from 7 a.m. to 10 p.m. Eastern. You answer a handful of questions about the LLC’s structure, ownership, and purpose, and at the end you get a PDF with your EIN on it. Save that PDF — the IRS only issues the confirmation letter once, and replacement letters take weeks.
If you apply online and meet every requirement, you have your EIN before you close the tab. If you apply by fax (Form SS-4), expect about four business days. Mail is painfully slow — plan on four to six weeks.
The online system requires an SSN or ITIN for the responsible party. If you have neither — which is common for non-U.S. residents forming an LLC — you’ll submit Form SS-4 by fax or mail instead. It usually takes a couple of weeks. We handle this flow automatically for our customers in that situation.
Our $49 flat filing service includes EIN assistance. You don’t need to juggle another government form.
When you file your LLC through us, we walk you through the EIN application right after your Articles are approved. The EIN itself is still free — the IRS doesn’t charge anyone — but you don’t have to figure out the SS-4 worksheet on your own or schedule yourself around the IRS’s weekday-only hours.
If you prefer to do it yourself, we’ll still link you to the right IRS page in your welcome email. No upsell.
Your EIN is federal, but a handful of states layer on their own taxes and filings that use it. Here’s the stuff people trip over most.
California LLCs pay the Franchise Tax Board $800/year minimum on top of federal taxes. Your EIN is how both agencies identify the entity.

Open the New York guide →Wyoming has no state income tax, so your EIN mostly matters for federal filings and opening a business bank account.

Open the Texas guide →Tennessee charges both a 6.5% excise tax on earnings and a franchise tax of $0.25 per $100 of net worth. Your EIN ties everything to the correct entity.

Technically the IRS lets single-member LLCs use the owner’s SSN. But try opening a business bank account without an EIN — you won’t get far. We’d recommend one for every LLC, full stop.
You can, but we don’t recommend it. If your Articles get rejected or you change the business name mid-filing, the EIN ends up attached to an entity name that doesn’t match your state records. Cleaner to form the LLC first, then apply.
Call the IRS Business and Specialty Tax Line at 800-829-4933. They can fax or mail you a Form 147C, which works the same as the original confirmation. It’s free, but plan on waiting on hold.
No. The IRS issues EINs for free. Any website charging $75, $149, or $299 to “register” one is reselling the same free form. If you’d rather not deal with it, our $49 filing service includes EIN assistance with zero upsell.
No. The EIN stays with the entity. You’ll update your address with the IRS (Form 8822-B) and register as a foreign LLC in the new state, but the EIN is permanent.
Yes. An S-corp election (Form 2553) doesn’t change your EIN — it changes how the IRS taxes the profits. Same number, different return.
Flat $49, plus whatever your state charges. No upsells, no surprises.
