How to Get an EIN for Your LLC
Getting an EIN for your LLC is free, fast, and unlocks everything from banking to hiring. Here’s exactly how it works.
What Is an EIN, Anyway?
An EIN — Employer Identification Number — is issued by the IRS and works like a Social Security number for your business. It’s how the IRS identifies your LLC on tax filings, and it’s what banks, payroll providers, and vendors will ask for before working with you.

How to Get an EIN for Your LLC
Confirm Your LLC Is Officially Formed
Your Articles of Organization should already be approved. The IRS wants your legal name and formation date to match what’s on file with your state.
Gather the Basic Information
Have your LLC’s legal name, address, formation date, and the responsible party’s SSN or ITIN ready before you start.
Apply Online Through the IRS
The IRS online EIN application is free and gives you your number immediately if completed in one sitting. Closing the window partway means starting over.
Or Apply by Mail or Fax
No SSN or ITIN? File Form SS-4 by mail or fax instead. Mailed applications take four to five weeks; faxed ones are usually back in about a week.
After You Get Your EIN
Your EIN never expires and doesn’t need renewing — it stays with your LLC for as long as the business exists. Save the IRS confirmation letter (Form CP 575) somewhere safe, since banks and lenders will often ask for it before opening an account or approving financing.
Common Questions About Getting an EIN
Can I get more than one EIN for the same LLC?
No — your LLC should only have one EIN, tied to its legal name and formation state.
What if I made a mistake on my application?
Minor errors can usually be corrected by writing to the IRS directly — just double-check everything before submitting.
Do I need a new EIN for a second LLC?
Yes. EINs are tied to the specific legal entity, not to you personally, so each LLC needs its own.
