How to Get an EIN for LLC: A Step-by-Step Guide for Small Business Owners (2025)

If you’ve just formed a Limited Liability Company (LLC), one of the first critical tasks is obtaining an Employer Identification Number (EIN). This nine-digit number, issued by the IRS, is essential for tax filing, opening a business bank account, hiring employees, and building business credit. In this comprehensive guide, we’ll walk you through how to get an EIN for LLC, covering costs, timelines, state comparisons, and frequently asked questions.

Whether you’re a solo entrepreneur or running a multi-member LLC, understanding the EIN process saves you time and prevents costly mistakes. Let’s dive in.

What Is an EIN and Why Does Your LLC Need One?

An EIN (also called a Federal Tax ID Number) is like a Social Security Number for your business. The IRS uses it to identify your LLC for tax purposes. While some single-member LLCs without employees can use the owner’s SSN, getting an EIN is still highly recommended for:

• Banking: Most banks require an EIN to open a business account.
• Tax compliance: You’ll need it to file federal and state taxes, especially if you elect S-corp or C-corp status.
• Hiring: Required for payroll taxes and W-2s.
• Privacy: Keeps your SSN off business documents.
• Credit: Builds business credit separate from your personal credit.

How to Get an EIN for LLC: Step-by-Step

Getting an EIN is free if you apply directly through the IRS. Follow these steps:

Step 1: Confirm You Need a New EIN

If your LLC is new, you need a new EIN. However, if you’re changing the business structure (e.g., from sole proprietorship to LLC) or ownership, you may need a new EIN. The IRS provides a Do You Need a New EIN? tool to help.

Step 2: Choose Your Application Method

You can apply online, by fax, or by mail. Online is fastest (immediate issuance). Fax takes about 4 business days, and mail can take 4-6 weeks.

Step 3: Gather Required Information

Before applying, have these ready:

• Responsible party’s name and SSN/ITIN (the person who controls the LLC)
• LLC’s legal name and trade name (if any)
• LLC’s mailing address and physical address
• State of formation
• Date of formation
• Number of members
• Reason for applying (e.g., banking, hiring employees)

Step 4: Apply Online (Recommended)

Go to the IRS EIN Assistant. The online application is available Monday-Friday, 7 AM to 10 PM ET. It takes about 15 minutes. You’ll receive your EIN immediately upon completion. Print the confirmation letter for your records.

Step 5: Apply by Fax or Mail (If Needed)

Download Form SS-4. Fax it to the IRS at 855-641-6935 (if you’re in the U.S.) or 855-215-1627 (if outside). For mail, send to the address for your state on the IRS website. Wait times: fax ~4 business days; mail ~4-6 weeks.

Step 6: Receive and Store Your EIN

Your EIN is permanent. Keep the confirmation letter (CP 575) safe. You’ll need it for tax filings, bank accounts, and credit applications.

For organized record-keeping, consider a fireproof document safe to store your EIN and other important business documents.

Cost and Time to Get an EIN for LLC

Cost: Applying directly with the IRS is free. Third-party services may charge $50-$300, but you don’t need them. Avoid scams that charge for a free service.

Time:

• Online: Immediate (15 minutes)
• Fax: 4 business days
• Mail: 4-6 weeks

If you need your EIN urgently, online is the way to go.

EIN Application by State: What to Expect

The EIN is federal, so the process is the same regardless of your LLC’s state. However, some states have additional requirements or offer state tax IDs. Here’s a comparison of common LLC states:

State	State Tax ID Required?	Additional Notes
Delaware	Yes (if hiring or selling taxable goods)	No state sales tax, but franchise tax applies
Wyoming	No state income tax; sales tax permit may be needed	Low fees, strong privacy
California	Yes (state employer ID, seller’s permit)	Annual minimum franchise tax $800
New York	Yes (if hiring or selling taxable goods)	Publication requirement for some LLCs
Texas	Yes (franchise tax, sales tax permit)	No state income tax

Always check your state’s revenue department for specific requirements. For a deeper dive, read our article on Best States to Form an LLC.

Common Mistakes to Avoid When Getting an EIN

• Using the wrong responsible party: This should be the owner or managing member, not an employee.
• Applying for multiple EINs: One EIN per LLC (unless structure changes).
• Paying for a free service: The IRS doesn’t charge for an EIN.
• Losing the confirmation letter: You can request a copy, but it takes time.
• Not updating the IRS: If your address or responsible party changes, file Form 8822-B.

After Getting Your EIN: Next Steps

Once you have your EIN, complete these tasks:

1. Open a business bank account (bring your EIN and formation documents).
2. Apply for state and local licenses/permits.
3. Set up business credit cards to build credit.
4. Hire employees and set up payroll (if applicable).
5. Consult a tax professional for ongoing compliance.

For a smooth start, consider business accounting software to track expenses and taxes.
