Learn how to get an EIN number free from the IRS in minutes: what an EIN is, who needs one, the step-by-step application, and the paid-service trap to avoid.

Learning how to get an EIN number takes about ten minutes, costs nothing, and happens entirely on the IRS website. An EIN (employer identification number) is the federal tax ID your business uses to hire employees, open a bank account, and file taxes, and the IRS issues it for free the moment your application is approved.
The catch is not the process. It is the noise around it. Plenty of third-party sites charge $50 to $300 to "get your EIN for you," and the thing they sell is a free government form. This guide covers what an EIN is, who actually needs one, and how to get an EIN number directly from the IRS, step by step, without paying anyone.
An EIN is a nine-digit number the IRS assigns to a business for tax filing and reporting. Think of it as a Social Security number for your company: the same kind of identifier, issued to the business instead of to you personally.
You will use your EIN to open a business bank account, hire and pay employees, file federal and state tax returns, and apply for many licenses and permits. It stays with the business permanently. An EIN is never reused, and it cannot be canceled, though the IRS can deactivate one you no longer need.
One thing an EIN is not: it is not a business license, and it is not the same as registering your company with your state. Those are separate steps that an EIN does not replace.
Not every business is required to have one. You generally need an EIN if any of the following apply:
If you run a sole proprietorship or a single-member LLC with no employees, the picture is different. For income tax, a single-member LLC is a disregarded entity, which means the IRS folds its income into your personal return and lets you use your own Social Security number instead of an EIN.
Most new owners get one anyway. A single-member LLC still needs an EIN to open a business bank account at most banks, and having one keeps your Social Security number off invoices, contracts, and W-9 forms. It is free, so there is rarely a reason to skip it.
The fastest route is the IRS online application, which issues your EIN immediately once you finish. Before you start, one sequencing rule matters: if you are forming an LLC, partnership, or corporation, register the entity with your state first. Applying before your state filing is on record is a common cause of delayed or mismatched applications.
Here is the process end to end:
One more limit to plan around: you can apply for only one EIN per responsible party per day. If you are setting up several entities at once, space the applications out across days.
These three numbers get confused constantly. Each is a taxpayer identification number, but they identify different things.
| Number | Identifies | Issued to |
|---|---|---|
| EIN | A business or entity | Employers, LLCs, corporations, partnerships, estates, trusts |
| SSN | A U.S. individual | Citizens and work-authorized residents |
| ITIN | An individual without an SSN | People with a federal tax purpose who are not eligible for an SSN |
If you have a Social Security number, you use it to apply for your business's EIN as the responsible party. If you are not eligible for an SSN, you first apply for an individual taxpayer identification number, or ITIN, and then use that to request the EIN.
The online application is the fastest option, but it is not the only one. If your principal business is outside the United States, or you would rather file on paper, you apply with Form SS-4, the application for an employer identification number. You can submit it by fax or mail, and international applicants can also apply by phone.
Paper and fax take longer than the online tool's instant result. Plan for several business days by fax and about four weeks by mail. The number you receive is identical either way.
This is worth repeating because it costs founders real money. The IRS issues EINs for free, and no one else can hand you a different or faster one. Search results are full of official-looking services that charge a fee to file the form on your behalf. Some are legitimate filing agents, many are not, and none of them offer anything you cannot do yourself in ten minutes.
The only place that issues your EIN is the IRS. If a page asks for a credit card to "get your EIN," close the tab.
An EIN handles your federal tax identity. Depending on where you operate and what you sell, you may also need a separate state tax ID for state income tax or sales tax. Those are different numbers from different agencies, and having an EIN does not automatically register you at the state level.
This is where an EIN, a state tax ID, entity registration, and licensing all start to blur together, even though they are separate steps. If you are still working through the sequence, how to register a business lays the steps out in order, and a business license is one more requirement an EIN does not cover.
Getting an EIN is one of the simplest official steps in starting a business, and one of the most over-sold. The application is free, it lives on the IRS site, and most owners finish it in a single session. Everything around it, from choosing a structure to the broader legal basics every founder should know, takes more thought than this step does.
