You're Going to Need This Number
If you're starting a business, you're going to hear about an EIN very quickly. Banks will ask for it. The IRS requires it. Contractors need it. Vendors ask for it before they'll work with you.
An EIN — Employer Identification Number — is your business's federal tax identification number. Think of it as the Social Security number for your company. It's how the IRS, financial institutions, and the business world at large recognize and track your entity.
Here's everything you need to know — and how to get yours for free.
What Is an EIN?
An Employer Identification Number (EIN) — also called a Federal Tax ID or FEIN (Federal Employer Identification Number) — is a unique 9-digit number assigned to your business by the Internal Revenue Service (IRS). It appears in the format XX-XXXXXXX and is used to identify your business entity for federal tax purposes.
Just like a Social Security number (SSN) identifies an individual to the government, an EIN identifies your business. It's used when you file business taxes, open a business bank account, pay employees, apply for licenses, and establish business credit.
Quick Reference: EIN by the numbers
- Format: XX-XXXXXXX (9 digits, separated by a hyphen after the first 2)

Why Does Your Business Need an EIN?
Even if you aren't required to have one by law, an EIN is practically essential the moment you start treating your business like a business. Here's what you need it for:
Open a Business Bank Account
Nearly every bank — and every financial institution worth using — requires an EIN to open a business checking account. Without it, you're mixing personal and business finances, which is one of the biggest mistakes new business owners make.
Hire Employees
If you bring on even one employee, you are legally required to have an EIN for payroll tax reporting, W-2 filings, and employer tax obligations. No EIN, no employees — period.
File Business Taxes
LLCs, corporations, partnerships, and nonprofits all use their EIN when filing federal income taxes, payroll taxes, and excise taxes. It's the number the IRS uses to track your business's tax activity.
Apply for Business Credit
Building business credit requires separating your personal finances from your business. Lenders, suppliers, and vendors use your EIN to pull your business credit profile — which is completely separate from your personal credit score.
Sign Contracts and Agreements
Many contracts, vendor agreements, and client engagements require your EIN so the other party can report payments to the IRS (via Form 1099). This is standard in B2B transactions.
Apply for Government Contracts and Grants
Federal contracting and grant applications require your EIN as part of the registration process — including SAM.gov registration for federal procurement.
Who Is Required to Get an EIN?
The IRS requires the following entities to obtain an EIN:
- All LLCs with employees: If your LLC hires employees, you must have an EIN — no exceptions.
- All corporations (C-Corp and S-Corp): Corporations are required to have an EIN regardless of whether they have employees.
- Nonprofits and 501(c)(3) organizations: Every nonprofit, church, and tax-exempt organization must obtain an EIN as part of their formation and IRS application process.
- Partnerships: Any business structure with two or more owners is classified as a partnership and requires an EIN.
- Sole proprietors who hire employees or have a Keogh plan: If you're operating as a sole proprietor but bring on staff or set up a Keogh retirement plan, you're required to get an EIN.
Bottom line: if you have an LLC, get an EIN. Period. Even if you don't technically need one yet, you'll need it the moment you try to open a bank account, take on a client, or grow your team. Get it done now — it's free and takes 10 minutes.
EIN vs. SSN — What's the Difference?
This is one of the most important distinctions new business owners need to understand — and one of the most commonly ignored.
| SSN (Social Security Number) | EIN (Employer Identification Number) | |
|---|---|---|
| Issued by | Social Security Administration (SSA) | Internal Revenue Service (IRS) |
| Identifies | An individual person | A business entity |
| Used for | Personal tax returns, personal credit | Business tax returns, business credit, banking |
| Risk if exposed | Identity theft, personal financial fraud | Business identity issues (far lower risk) |
| Cost to obtain | N/A (issued at birth/citizenship) | Free at IRS.gov |
The key risk: When you use your SSN for business purposes — giving it to clients, vendors, or on invoices — you're exposing your most sensitive personal identifier to unnecessary risk. A data breach at a client's company, a compromised invoice, or a careless email could put your personal finances and credit in jeopardy.
An EIN creates a clean wall between your business identity and your personal identity. It keeps your SSN where it belongs — on your personal tax returns and nowhere else.
How to Get an EIN (Step-by-Step)
The IRS makes this surprisingly simple. Here's the exact process:
Go to IRS.gov — the Official Site
Navigate to the IRS EIN application page at irs.gov/businesses/small-businesses-self-employed/apply-for-an-employer-identification-number-ein-online. This is the only official source — do not use any third-party website. Several sites will charge $50–$100 to 'apply for your EIN' — that's money wasted on a completely free service.
Confirm Eligibility
The online application is available Monday through Friday, 7am to 10pm Eastern Time. To apply, the responsible party (the owner or principal officer) must have either a Social Security number (SSN) or an Individual Taxpayer Identification Number (ITIN). You must apply for your LLC's EIN after your LLC is officially formed — not before.
Complete the Online Application
The application will ask for your business name (exactly as it appears on your LLC filing), business address, type of entity (LLC, corporation, nonprofit, etc.), reason for applying, and the responsible party's name and SSN or ITIN. The process takes 5–10 minutes.
Receive Your EIN Immediately
Once you submit the application, your EIN is issued immediately — right on the screen. Print or save your EIN confirmation (Form SS-4 confirmation) right then. You'll also receive a confirmation notice (CP 575) by mail within 4–5 weeks.
Save Your CP 575 Letter
The CP 575 letter the IRS mails you is your official EIN assignment letter. Banks, vendors, and government agencies may ask for it. Keep it in a safe place — it cannot be reissued in the same format (only a replacement 147C letter can be obtained if you lose it).
Common EIN Mistakes to Avoid
These three mistakes trip up new business owners every single day:
- Applying before your LLC is officially formed: Your EIN must be tied to an existing legal entity. If you apply before your state has processed your Articles of Organization, you risk creating a mismatch between your EIN records and your state filings. Form your LLC first — then apply for your EIN.
- Using a third-party EIN service that charges a fee: Applying for an EIN on IRS.gov is completely free. Period. If a website is charging you $50–$100 for 'EIN registration,' they are charging you for a free government service. Always go directly to IRS.gov.
- Losing your CP 575 letter: Your EIN confirmation letter (CP 575) is the official document banks and government agencies want to see. It is only issued once. If you lose it, you can request a 147C letter from the IRS by calling 800-829-4933 — but that process takes time and effort. Save your CP 575 the moment it arrives.
What Comes After Your EIN?
Getting your EIN is a major milestone — but it's not the finish line. Here's what to do next:
Open Your Business Bank Account
Take your EIN confirmation and your LLC formation documents to the bank. Opening a dedicated business checking account is non-negotiable — it's how you keep business and personal finances separate and build the financial credibility lenders look for.
Register for State Taxes (if applicable)
Depending on your state, you may need to register for state income tax, sales tax, or employer withholding accounts. Check your state's department of revenue website — your EIN is required for this registration.
Apply for Your D-U-N-S Number
Your EIN identifies you to the IRS. Your D-U-N-S number (from Dun & Bradstreet) identifies you to the business credit world. You'll need it for government contracts, SBA loans, and building your Paydex score.

Under the Corporate Transparency Act, most LLCs and corporations are required to file a Beneficial Ownership Information (BOI) report with FinCEN. This is a federal compliance requirement — missing the deadline can result in significant penalties.

Frequently Asked Questions
Is an EIN free?
Yes — applying for an EIN on IRS.gov is completely free. The IRS does not charge any fee for EIN registration. Be aware that many third-party websites charge $50–$100 to 'apply for your EIN' on your behalf — this is unnecessary. Always apply directly at IRS.gov to get your EIN at no cost.
How long does it take to get an EIN?
If you apply online at IRS.gov, your EIN is issued immediately at the end of the application — in under 10 minutes. If you apply by fax, you'll typically receive your EIN within 4 business days. If you apply by mail, expect 4–5 weeks. For most new businesses, the online application is the fastest and simplest option.
Do I need an EIN if I'm a sole proprietor?
Sole proprietors are not required to have an EIN unless they hire employees or maintain a Keogh retirement plan. However, getting an EIN is strongly recommended even for sole proprietors — it protects your Social Security number by giving you a separate tax ID to use on invoices, client agreements, and vendor forms. It's a free step that significantly reduces your identity theft risk.
Can I have multiple EINs?
Each separate business entity gets its own EIN. If you have an LLC and later form a second LLC, the second business gets a new, separate EIN. You cannot use one EIN for multiple distinct businesses. However, a single business entity has exactly one EIN — you do not receive a new EIN if you move, change your business name, or add members (for an LLC), unless the entity type itself changes.
What if I lose my EIN?
If you've lost your EIN, you have several options: check any previously filed tax returns, look at your original IRS confirmation email or CP 575 letter, or check documents where you've used it (bank account applications, loan applications, contracts). If you still can't locate it, call the IRS Business & Specialty Tax Line at 800-829-4933 (Monday–Friday, 7am–7pm local time). They can look up your EIN and issue a 147C letter as official confirmation.
