What is an EIN and does a freelancer need one? (2026)

An EIN — Employer Identification Number — is a nine-digit number the IRS assigns to businesses. It works like a Social Security number but for your business. Getting one is free, takes about five minutes, and is one of the first things many freelancers should do — even though not all freelancers are technically required to have one. Here's when you need it, when you don't, and why getting one even when it's optional is often the smart move.

When you are required to have an EIN

The IRS requires an EIN if any of the following apply to your freelance business:

• You have employees (even one part-time hire or a paid intern)
• You operate as a partnership, LLC taxed as a partnership, or corporation
• You file excise tax returns (applies to certain industries like alcohol, firearms, or tobacco)
• You withhold taxes on income paid to a non-resident alien
• You have a Keogh retirement plan
• You are involved with trusts, estates, non-profits, or certain other entities

If none of these apply — you're a solo freelancer operating as a sole proprietorship with no employees — the IRS does not require you to have an EIN. You can use your Social Security Number for all tax filings.

When you don't need one — but should get one anyway

Even if you're not technically required to have an EIN, there are several practical reasons most freelancers should get one:

Opening a business bank account. Most banks require an EIN to open a business checking account. Separating business and personal finances is one of the highest-impact financial habits for freelancers — it simplifies bookkeeping, makes tax filing easier, and protects you in an audit. See our best business bank accounts for freelancers guide for options that work well with a new EIN.

Protecting your Social Security Number. Without an EIN, every client who pays you $600+ will need your SSN to file their 1099. That's your SSN sitting in the accounting systems of every company you work with. An EIN lets you give clients a business identifier instead of your personal one — reducing your exposure to identity theft.

Clients and platforms sometimes require it. Some enterprise clients, agencies, and gig platforms require an EIN before they'll issue payments or onboard you as a contractor. Having one ready avoids delays when you land a new client.

Building business credit. An EIN is the first step toward establishing a business credit profile separate from your personal credit. This matters if you ever want a business credit card, a line of credit, or a loan under your business name. It's also part of the documentation package when you apply for a mortgage as a self-employed person.

Forming an LLC or S-Corp later. If you ever structure your freelance business as an LLC or elect S-Corp status (something worth considering once you consistently earn above $75,000–$80,000 net — see our self-employment tax guide for why), you'll need an EIN. Getting one now means it's ready when you need it.

How to get an EIN (free, 5 minutes)

The IRS issues EINs for free. Do not pay a third-party service to get one — any site charging you $50–$200 for an EIN is charging you for something the IRS does at no cost.

Online (fastest — immediate)

Go to the IRS EIN Assistant at irs.gov/businesses/small-businesses-self-employed/apply-for-an-employer-identification-number-ein-online. The application is available Monday through Friday, 7:00 AM to 10:00 PM Eastern. You'll answer a series of questions about your business type and receive your EIN immediately upon completion.

For most freelancers, here's what you'll select:

• Entity type: Sole proprietor (unless you've formed an LLC)
• Reason for applying: Banking purposes (if that's your primary reason) or Started a new business
• Principal activity: Select the category closest to your freelance work

You'll receive your EIN on screen as soon as you submit. Print or save the confirmation — this is your official EIN assignment notice (CP 575). The IRS mails a paper copy within 4–6 weeks, but the on-screen confirmation is valid immediately.

By mail or fax (slower)

You can also submit Form SS-4 by fax (response in about 4 business days) or by mail (response in 4–6 weeks). There's rarely a reason to use these methods unless you don't have access to the online system.

EIN vs. SSN vs. ITIN — what's the difference?

As a freelancer, you can use either your SSN or your EIN on a W-9 form when clients ask for your tax information. If you have an EIN, use it — it keeps your SSN off the form.

What to do with your EIN after you get it

• Open a business bank account. Bring your EIN confirmation letter (CP 575) and your ID to the bank, or apply online. This is the single most impactful next step — it separates business and personal money. See our recommended accounts.
• Update your W-9. When clients ask you to fill out a W-9, use your EIN instead of your SSN in the "Employer identification number" field.
• Store it securely. Your EIN doesn't change (unlike a phone number or address). Save the CP 575 confirmation in the same place you keep other important tax documents.
• Use it on Schedule C. When you file taxes, you can enter your EIN on Schedule C, Line D. This is optional for sole proprietors (your SSN works too), but using the EIN keeps everything consistent.
