An EIN is free and easy to get — but do you actually need one? Here's when it's required, when it's optional, and when it just makes sense to get one anyway.
In This Guide
An Employer Identification Number (EIN) is a nine-digit number the IRS uses to identify your business for tax purposes — think of it as a Social Security number for your company. It's free to get, issued immediately when you apply online, and used on tax returns, bank applications, business licenses, and many other documents.
If you're a sole proprietor with no employees, you can generally use your Social Security number for tax purposes. However, many sole proprietors still get an EIN to avoid handing out their SSN on forms, contracts, vendor paperwork, and banking applications. It's a simple way to protect your personal information.
If you formed an LLC, you should get an EIN — even as a single-member LLC. Banks typically require one to open a business account, and it helps keep your business identity separate from your personal one. Some states also use your EIN on tax filings and registration documents.
You can apply for an EIN online through the IRS website at no cost. The application takes just a few minutes, and the number is issued immediately after you complete it. There's no reason to pay a third-party service for something the IRS provides for free.
Even if you're not legally required to have an EIN, getting one is often a smart move. It lets you separate your personal and business identity, reduces how often you share your SSN, and makes it easier to open accounts, sign contracts, and handle paperwork down the road.

In most cases, yes. While the IRS may treat a single-member LLC as a 'disregarded entity' for tax purposes, banks almost always require an EIN to open a business account. Getting one also keeps your business identity separate from your personal one.
Nothing. The IRS issues EINs for free through its online application. You should never pay a third-party service for the number itself — some companies charge for convenience, but you can do it yourself in minutes at no cost.
If you apply online through the IRS website, your EIN is issued immediately after you complete the application. You can start using it right away for banking, tax filings, and licensing.
An EIN is generally permanent — you usually don't get a new one if your business changes structure or location. If you close your business, you can notify the IRS, but the number itself isn't reused. For major changes like switching entity types, it's best to check with a tax professional.
