An EIN is your business's federal tax ID. You need it to open a bank account, hire employees, and file taxes. Here's exactly how to get one for free.
An EIN (Employer Identification Number) is a nine-digit federal tax ID assigned to your business by the IRS. Think of it as your LLC's Social Security Number — it identifies your business entity for tax and financial purposes.
The good news: it's free, it takes about 10 minutes, and you get your number immediately. There is no reason to pay a third-party service for EIN filing.
Even if you have no employees and don't plan to hire anyone, you still need an EIN for your LLC to open a bank account and keep your business finances separate from personal.
Yes. Technically, a single-member LLC without employees can use your Social Security Number for federal tax purposes. But in practice, you should always get an EIN. Banks require it. It protects your SSN from being shared unnecessarily. And it keeps your business and personal identity cleanly separated.
Your EIN is displayed on screen immediately after submission. Save the confirmation page — the IRS also emails a copy, but it's smart to screenshot the number right away.
Apply for your EIN immediately after your Articles of Organization are approved — or even before, if you're filing yourself and know your LLC name. You'll need the EIN to open a business bank account, which should be one of your first moves after formation.
The online IRS application requires a U.S. Social Security Number or Individual Taxpayer Identification Number (ITIN) for the responsible party. If you don't have one, you can apply by fax or mail using Form SS-4. The process takes 4–6 weeks.
