How to Get an EIN Number for Your Business (Free)

An electrician in Spring came to us convinced he had done something wrong. He had opened his business, started taking jobs, and three months in his bank turned him away when he tried to open a business account. The teller asked for his EIN. He did not have one, and he did not know what it was.

Nothing was wrong. He had simply skipped a step that takes about ten minutes and costs nothing. An EIN is one of the first things a new business should set up, and getting one is far simpler than most owners expect.

Here is what an EIN is, who actually needs one, and exactly how to get it for free.

What an EIN Is

An EIN, or Employer Identification Number, is a nine-digit number the IRS assigns to a business. It works like a Social Security number for your company. The IRS uses it to identify your business on tax filings, and banks, payroll providers, and vendors use it to identify you too.

The name is misleading. “Employer” makes it sound like the number is only for businesses with employees. That is not true. Plenty of businesses with zero employees need or want an EIN, which we will get to below.

You may also hear it called a Federal Tax ID or a business tax ID. Those are the same thing. An EIN is a specific kind of tax ID issued to businesses.

Who Needs an EIN

The IRS requires an EIN if any of the following are true for your business:

• You have employees, or you plan to hire.
• Your business is a corporation or a partnership.
• You file employment, excise, or certain other federal tax returns.
• You have a Keogh or solo retirement plan.
• You withhold taxes on income paid to a non-resident.

If you run a single-member LLC with no employees, or you operate as a sole proprietor, the IRS does not strictly require an EIN. You can use your Social Security number for federal taxes. But “not required” is not the same as “skip it.”

Why You Want One Even If It Is Not Required

Most one-owner businesses get an EIN anyway, for three practical reasons.

Banks ask for it. Most banks require an EIN to open a business bank account for an LLC or any business entity. Keeping business and personal money separate is one of the foundations of clean books, and the account starts with an EIN.

It keeps your SSN private. Every time you fill out a vendor form or hand a client a W-9, you write down a tax ID. If you have no EIN, that means your Social Security number goes on paperwork that passes through other people’s hands. An EIN lets you keep your personal number out of circulation. This matters even more once you start receiving 1099 forms from clients.

It makes you look established. An EIN signals that you are running a real business, not a side hustle. Some clients and suppliers will not set up an account without one.

The choice of entity affects whether you are required to have an EIN, which is one of many reasons to think through LLC vs. sole proprietorship before you start operating.

How to Get an EIN Online (The Free Way)

The IRS issues EINs directly at no cost. The online application is the fastest method, and it is the one most business owners should use.

Here is the process:

1. Go to the official IRS site. Search for “IRS EIN application” and confirm the address ends in irs.gov. Do not use a third-party site that charges a fee for something the government provides free.
2. Start the application during operating hours. The online tool runs roughly Monday through Friday, 7 a.m. to 10 p.m. Eastern. You must finish in one sitting, because the session times out after fifteen minutes of inactivity and does not save.
3. Choose your entity type. Sole proprietor, single-member LLC, multi-member LLC, corporation, partnership, and so on. This tells the IRS how your business is taxed.
4. Enter the responsible party. This is the person who controls the business, usually the owner. You will need their Social Security number or ITIN.
5. Provide business details. Legal name, mailing address, county and state, the date you started, and your main business activity.
6. Submit and receive the number instantly. At the end you get your EIN on screen. Download and save the confirmation notice, called the CP 575, right then. It is the cleanest proof you will get.

That is the entire process. No fee, no waiting, no middleman.

The Other Application Methods

Online is best for most people, but there are alternatives:

Method	Who it is for	Time to receive
Online	Applicants with an SSN or ITIN	Immediate
Fax (Form SS-4)	Anyone, including no SSN	About 4 business days
Mail (Form SS-4)	Anyone, no rush	About 4 weeks
Phone	International applicants	During the call

If you do not have a Social Security number or an ITIN, the online tool will not work for you. You apply using Form SS-4 by fax or mail, following the SS-4 instructions for responsible parties without a US taxpayer ID.

Common Mistakes That Cause Delays

The application is short, but a few errors trip people up.

Paying a third-party site. Search results are full of services that charge $50 to $300 to “get your EIN fast.” They are filling out the same free form you can fill out yourself. There is nothing they can do that you cannot.

Applying before the business exists. Get your entity set up first. If you are forming an LLC, complete the state filing before you request the EIN so the legal name on the application matches your formation documents. Our guide on how to start an LLC in Texas walks through that order.

Naming the wrong responsible party. The responsible party must be a real person who controls the business, not another company. Entering a business as the responsible party is a frequent rejection reason.

Applying for more than one EIN a day. The IRS limits responsible parties to one EIN per day. If you are setting up several entities, spread the applications across days.

Losing the confirmation. Save the CP 575 notice the moment you get it. If you lose your EIN later, you can call the IRS to retrieve it, but that is a phone call you can avoid by saving the file.

After You Have Your EIN

The number is not the finish line. Once you have it, put it to work:

• Open your business bank account.
• Set up payroll if you have employees or plan to pay yourself through an S corp election, which may involve Form 2553.
• Use it on W-9s, invoices, and vendor forms instead of your SSN.
• Give it to your bookkeeper or accountant so it appears correctly on every filing.

Keep the number somewhere secure and accessible. You will use it for the life of the business.

Get It Done Right the First Time

Getting an EIN is simple, but it sits inside a larger set of decisions about entity type, banking, and how your business is taxed. Getting those in the right order saves cleanup later.
