How to Get an EIN Number: A Simple Guide for Small Business Owners

If you're starting a business, opening a business bank account, or planning to hire employees, you'll need an Employer Identification Number — commonly called an EIN. It's like a Social Security number for your business.

The good news? Getting one is free, fast, and simpler than most people expect. Here's everything you need to know.

What Is an EIN?

An EIN (Employer Identification Number) is a nine-digit number the IRS assigns to businesses for tax purposes. Think of it as your business's federal tax ID.

You'll use your EIN to:

Open a business bank account

File business tax returns

Apply for business licenses and permits

Hire and pay employees

Establish business credit

Work with vendors who require a tax ID

Who Needs an EIN?

Not every business needs an EIN, but most do. You're required to get one if:

You have employees

You operate as a partnership or corporation

You file certain tax returns (employment, excise, or alcohol/tobacco/firearms)

You withhold taxes on income paid to a non-resident

You have a Keogh plan (a retirement plan for self-employed individuals)

Even if you're not required to have an EIN, many sole proprietors and single-member LLCs get one anyway. Why? Because using an EIN instead of your personal Social Security number:

Protects your SSN from exposure when filling out client paperwork

Looks more professional to clients and vendors

Is required by most banks to open a business account

Helps separate your business and personal finances

How to Apply for an EIN (Step by Step)

Applying for an EIN is free and takes about 15 minutes. Here's the process:

Step 1: Make Sure You're Eligible

To apply, you need a valid Taxpayer Identification Number — your Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN). You also need to be the "responsible party" for the business — the person who controls, manages, or directs the business.

Step 2: Gather Your Information

Before you start, have this ready:

Your name and SSN (or ITIN)

Your business's legal name and trade name (if different)

Your business's mailing address

The type of business entity (sole proprietorship, LLC, partnership, corporation)

The number of employees you expect to hire (if any)

The primary business activity

Step 3: Apply Online (Fastest Method)

The IRS offers a free online application at irs.gov/ein. It's available Monday through Friday, 7:00 AM to 10:00 PM Eastern Time. The application walks you through a series of questions and issues your EIN immediately upon completion.

This is by far the fastest and easiest method. Most people finish in under 15 minutes.

Step 4: Alternative Methods

If you can't or prefer not to apply online, you can also:

**Apply by fax:** Complete Form SS-4 and fax it to the IRS. You'll receive your EIN by fax in about 4 business days.

**Apply by mail:** Complete Form SS-4 and mail it to the IRS. Processing takes about 4 weeks.

**Apply by phone:** International applicants can call the IRS at 267-941-1099 (not a toll-free number).

How Long Does It Take?

| Method | Processing Time |

|--------|----------------|

| Online | Immediate |

| Fax | ~4 business days |

| Mail | ~4 weeks |

| Phone (International) | Immediate |

How Much Does It Cost?

Nothing. Applying for an EIN through the IRS is completely free. If you see a website charging you to apply, it's a third-party service — skip it and go directly to irs.gov.

Common Mistakes to Avoid

**Paying for a free service.** The IRS does not charge for EIN applications. Third-party sites that charge $50–$100 are selling convenience, not access.

**Applying before forming your business entity.** If you're forming an LLC, form the LLC with your state first, then apply for the EIN using the LLC's legal name.

**Using your SSN on client paperwork.** Once you have your EIN, use it for all business tax forms and client documentation. Keep your SSN private.

**Forgetting to save your EIN confirmation.** When you apply online, save or print the confirmation notice immediately. You'll need it for bank applications and tax filings.

What to Do After You Get Your EIN

Once your EIN is in hand, here's your next-steps checklist:

1. Open a business bank account — Most banks require an EIN to open a business account. This is essential for keeping your business and personal finances separate.

2. Update your business records — Store your EIN confirmation letter somewhere safe and accessible.

3. Apply for business licenses — Many state and local business license applications ask for your EIN.

4. Set up your business online presence — With your legal entity formed and your EIN secured, you're ready to establish your brand with a professional website.
