How To Get An EIN For An LLC Step-By-Step (2026)

What an EIN Is

An EIN is a nine-digit number that works like an SSN for businesses. It helps track your taxes, and it also establishes your business as a legal entity separate from yourself.

Does Your LLC Need an EIN?

If you’re figuring out how to start an LLC, there are several steps to take, including getting an EIN. If your LLC meets any of the following criteria, it’s legally required to have an EIN:

• Has multiple members
• Is a single-member LLC with employees
• Is required to file excise tax forms

If you have a single-member LLC without employees, you generally don’t have to get an EIN. However, getting one can legitimize your company and establish it as a distinct legal entity.

What to Prepare Before You Apply

Before you apply, make sure you have the following ready:

• The official legal name of your LLC
• Business location and mailing address
• Your SSN or individual taxpayer identification number (ITIN)
• Your business entity type

To avoid processing delays, you should apply for an EIN after registering your LLC with your state’s secretary of state.

How to Apply for an EIN Online

One of the main benefits of an LLC is that it’s relatively straightforward to set up. The IRS has an online tool you can use to get your LLC’s EIN for free, and it only takes minutes.

Applying by Mail, Fax or Phone

Applying online is the fastest option. If you would rather apply by mail, you must fill out and send Form SS-4. Typically, you may only apply by phone if your principal place of business is outside of the United States.

Common Errors and How to Fix Them

These are a few errors to watch for when you apply:

Name Mismatches

Always double-check that your LLC’s name on the EIN application is the same as it is on your articles of organization.

SSN/ITIN Typos

It’s easy to mix up numbers in your SSN or ITIN. Verify that you’ve typed all numbers correctly before you submit.

If you made a mistake on an application you already submitted, you’ll probably need to send a signed correction letter. You should contact the IRS to ask for specific instructions first.

What to Do After You Get It

Once you get an EIN, you can open a business bank account and register with state or local tax agencies, if required. If you have to apply for local permits or licenses, you’ll probably need your EIN to do so.
