You’ve finally done it. You have the business idea, the domain name is bought, and you’re ready to actually make some money. But then you hit the wall. You need that nine-digit string of numbers known as the Employer Identification Number. Honestly, the question how do i apply for my ein number is one of those things that sounds like it should be a massive bureaucratic nightmare, but it’s actually one of the few things the IRS has made surprisingly simple. If you do it right. If you do it wrong, you end up waiting weeks for a piece of mail that could have taken five minutes to generate.
Think of an EIN as a Social Security number for your business. You need it to open a bank account, hire your first employee, or even just to get certain business licenses. It’s the gateway to being "official."
The Most Direct Path: The IRS Online Portal
The absolute best way to handle this is through the IRS website. It’s open Monday to Friday, from 7:00 a.m. to 10:00 p.m. Eastern time. Don't ask me why a website has "business hours," but it does. If you try to do this at midnight on a Saturday, the system will just be "down for maintenance." It’s quirky, but that’s the government for you.
When you land on the official IRS.gov page, look for the "Apply for an Employer ID Number (EIN) Online" section. You’ll want to make sure you have your own Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN) handy. You are the "Responsible Party." That’s IRS-speak for the person who actually controls or manages the entity. You can't just put a random employee's name here; it has to be a principal officer, general partner, or the owner.
The session times out fast. Like, really fast. If you get distracted by a TikTok or go to grab a cup of coffee, you'll probably have to start over from scratch. Have all your info ready before you click "Begin Application."
Who Can Actually Apply Online?
Not everyone gets to use the fast lane. To use the online application, your principal business must be located in the United States or U.S. Territories. Also, the person applying must have a valid Taxpayer Identification Number. If you’re an international founder without an SSN or ITIN, you’re stuck with the paper route. It sucks, but that's the reality of the current system.

Paperwork and the Snail Mail Alternative
Maybe you’re old school. Or maybe you’re an international applicant. In that case, you’re looking at Form SS-4. This is the physical (or PDF) version of the application. You can find it easily on the IRS website by searching for "Form SS-4."
If you fax this form to the correct IRS fax number (which changes based on where your business is located), they generally get back to you within four business days. If you mail it? Pack your patience. You’re looking at a four to five-week lead time. It’s the difference between getting your business bank account open next week versus next month. For international applicants without a legal residence or principal place of business in the U.S., you can actually call the IRS at 267-941-1099. This is not a toll-free number, but they can often process the EIN over the phone right then and there.
Common Mistakes That Delay Everything
People mess this up all the time. One big one: applying for a new EIN when you don't actually need one. If you’re just changing the name of your business, you usually don't need a new number. But if you’re moving from a Sole Proprietorship to a Corporation, yeah, you need a new one.
Another trap is the "Third Party Designee." If you’re having your accountant or lawyer do this for you, you have to authorize them in a specific section of the form. If that’s not filled out perfectly, the IRS will reject the application or refuse to talk to your representative.
- The "One Per Day" Rule: The IRS limited this a few years ago. One "responsible party" can only receive one EIN per day. If you’re trying to launch a fleet of ten LLCs at once, you’re going to have to spread that work out over a couple of weeks.
- Legal Name Issues: Your business name must match exactly what you filed with the Secretary of State. If you’re "Jones Consulting LLC" on your state papers but you type "Jones Consulting" on the EIN app, you’re asking for a headache later when you try to file taxes.
What Happens After You Get the Number?
Once the screen pops up with your nine digits—or you get that letter in the mail—save it. Print it. Save it as a PDF in three different cloud drives. Email it to your mom. Whatever you have to do. While you can call the IRS to recover a lost EIN, the wait times on their phone lines are legendary in a bad way. You might be on hold for two hours just to get a number you already had.
You’ll use this number for your Form 941 (Employer’s Quarterly Federal Tax Return) and your annual income tax returns. It’s also what you’ll give to any company that sends you a 1099. It’s your business’s public face to the financial world.
The Fraud Warning: Don't Pay for This
Here is something that really grinds my gears. There are dozens of websites out there that look very official—lots of eagles and red-white-and-blue banners—that offer to "help" you apply for an EIN for a fee of $50, $100, or even $300.
Applying for an EIN is free.

The IRS does not charge a penny for this. These third-party sites are basically just taking the information you give them, typing it into the free IRS website themselves, and pocketing your cash. Unless you are paying a CPA for broad business setup advice, never pay someone just to "get" you an EIN. It's a total scam. Go directly to IRS.gov. If the URL doesn't end in .gov, you're in the wrong place.
Choosing the Right Business Type
When you are sitting there wondering how do i apply for my ein number, you have to know what kind of entity you are. The IRS asks this early on.
- Sole Proprietorship: It’s just you. You might not even need an EIN if you don't have employees, but many people get one anyway to avoid giving out their Social Security number to clients.
- LLC: This is the most common for new small businesses. Even a single-member LLC can get an EIN.
- Corporation: S-Corps and C-Corps always need them.
- Partnerships: If you have a business partner, the IRS wants you to have a distinct ID for the entity.
The IRS will also ask "Why are you applying?" Common answers include "Started a new business," "Hired employees," or "Banking purposes." Don't overthink this. Just pick the one that most closely fits. "Started a new business" is usually the safe bet.
Actionable Steps for a Smooth Application
To make sure this goes off without a hitch, follow this specific sequence.
First, ensure your business is actually registered with your state. If you apply for an EIN for "Superfast Delivery LLC" but the state rejects that name because someone else has it, your EIN is now tied to a business name you can't use. It’s a mess to fix.

Second, gather your documents. You need your SSN, the legal names of any partners, and the physical address of the business. No P.O. boxes allowed for the physical location, though you can use one for the mailing address.
Third, set aside 20 minutes of uninterrupted time during IRS business hours. Open your browser, go to the official site, and move through the screens steadily. Once you finish, the system will generate a "Confirmation Notice" (Form CP 575). Download this immediately. This is the official document that banks will demand to see. If you close the window without saving it, you'll be waiting weeks for the paper copy to arrive in the mail.
Finally, take that number and go get your business bank account. Keeping your personal and business finances separate is the single best thing you can do for your sanity and your legal protection. Now that you have the EIN, that door is wide open. Do not delay this step; the longer you mix funds, the harder it is to untangle them when tax season rolls around.
If you’ve followed these steps, you’re no longer just a person with an idea. You’re a business owner with a tax ID. It’s a small hurdle, but jumping over it feels pretty great. Keep that CP 575 form safe, and you're ready to start hiring, banking, and growing.
