Jan. 30, 2026, 6:56 p.m.
An Employer Identification Number (EIN) is a unique nine-digit number issued by the IRS to identify your business for tax and reporting purposes. It acts like a Social Security Number for your business and is essential for most companies operating in the United States.

When Should You Apply for an EIN?

You should apply for an EIN as soon as your business is legally formed and you plan to:

  1. Hire employees – Even if you don’t have employees immediately, planning to hire requires an EIN for payroll taxes.

  2. Operate as a corporation or partnership – LLCs with multiple members, partnerships, and corporations must have an EIN.

  3. Open a business bank account – Most banks require an EIN to open a business account.

  4. Apply for business licenses or permits – Certain permits, including state tax registrations, require an EIN.

  5. File federal taxes – All businesses except sole proprietorships without employees need an EIN for tax filing.

  6. Form an LLC as a single-member entity – While optional in some cases, obtaining an EIN is recommended for separating personal and business finances.

Best Timing for Applying

  • Immediately after registering your business: Once your LLC, corporation, or partnership formation is complete.

  • Before hiring employees: You’ll need the EIN to report payroll taxes.

  • Before opening a bank account: Banks usually require proof of your EIN to open accounts.

  • Before filing certain tax forms: Forms like excise taxes or employment taxes often require an EIN.
