Application Process
How do I get an Employer Identification Number (EIN)?
Apply free on the IRS website at IRS.gov/EIN — the online application takes about 15 minutes and delivers your EIN immediately upon completion. Most businesses, including sole proprietors with employees, need one.
The full picture
An Employer Identification Number (EIN) — also called a Federal Tax Identification Number — is a nine-digit number the IRS uses to identify a business entity for tax purposes. It functions like a Social Security Number for your business. You'll need one to open a business bank account, hire employees, file business taxes, and apply for most business financing. The IRS EIN application is entirely free and handled directly through IRS.gov.
Who needs an EIN?
- All corporations and partnerships — required regardless of whether you have employees.
- LLCs with more than one member, or any LLC that has elected corporate tax treatment.
- Sole proprietors and single-member LLCs that hire employees or file excise or pension taxes.
- Estates, trusts, and non-profit organizations.
- Any business that opens a dedicated business bank account (most banks require one).
How to apply: online (fastest)
The IRS online EIN application is available Monday–Friday, 7 a.m.–10 p.m. Eastern. You must be the responsible party (a natural person who controls the entity — not another business), and you'll need a valid Taxpayer Identification Number (SSN or ITIN) to complete the form. The IRS issues your EIN immediately at the end of the session. Print or save the confirmation — the IRS will not re-issue it online.
Alternative application methods
- By fax: Submit IRS Form SS-4 to the IRS fax line for your state — typically 4 business days.
- By mail: Mail a completed Form SS-4 — up to 4 weeks.
- International applicants without an SSN/ITIN: call the IRS international line (not toll-free).
EIN and business financing
Lenders require your EIN on every business loan or line-of-credit application — it links your business identity, tax filings, and credit profile. Having an EIN also lets you start building a separate business credit file (via Dun & Bradstreet, Experian Business, and Equifax Business) that doesn't depend solely on your personal credit score. Once your entity and EIN are established, apply with ClearValue Lending to see which financing options fit your business profile — one application routes to the funding partners best matched to it. Consult a CPA or tax professional if you're unsure which entity type to use before applying for your EIN.
