Starting a business is exciting, but the paperwork can feel like trying to read a foreign language at times. Names, forms, tax rules, government requirements… It’s a lot to digest. One question I hear from many new business owners is: How do I apply for an EIN number, and what exactly do I need before submitting an application?
The good news is, getting an Employer Identification Number (EIN) is usually a lot easier than people think. The process is handled by the IRS, and in many cases you can complete the application online in minutes. But knowing what you need before you start can save you from unnecessary delays or mistakes.
Starting an LLC? Hiring your first employee? Opening a business bank account? Separating your personal and business finances? Whatever your reason, this guide will take you through everything you need to know about applying for an EIN, including eligibility, application methods, required information, and common mistakes to avoid.
What Is an EIN Number and Why Your Business Requires One
An Employer Identification Number, or EIN, is a unique nine-digit number that the Internal Revenue Service (IRS) assigns to businesses and organizations for tax identification purposes. Think of it as your business’s Social Security number. It helps the government to record tax activities relating to the business and not your personal financial activities.
Many people think you only need an EIN if you have employees. One of the most common reasons to get one is to hire workers. Businesses often need an EIN for several other reasons. An EIN is often obtained by LLC owners when opening a business bank account, filing certain taxes, or setting up a more formal financial infrastructure.
Imagine you are starting a small online business from your home. Initially, you might do all the work yourself, from packing orders to answering customer queries. However, as your business expands, you may need a separate bank account, payment processing tools, or employees. That is where an EIN comes in extremely handy.
An EIN also allows you to separate your personal identity from your business operations. Your EIN is your official business identifier instead of providing your personal Social Security number for every business activity.
Who Must Apply for an EIN Number?
While not all new business owners will need an EIN right away, many will need one at some point depending on their structure, activities or tax responsibilities. Sometimes an individual who has no employees uses their Social Security number for tax purposes. But many obtain an EIN as it provides better privacy and a more professional face when dealing with banks, vendors and customers.
LLCs are one of the most popular types of businesses that apply for EINs. The requirements may vary depending on whether the LLC has a single owner or multiple owners and how it chooses to be taxed.
Corporations and partnerships usually need an EIN because they are separate legal entities that must file their own taxes. Companies that have employees also need an EIN to handle payroll taxes, report on employees, and meet other employer requirements.
Depending on their activities, some other types of entities that may need an EIN include nonprofit organizations, trusts, and estates. Here’s a simple way to look at it: if your business has responsibilities that extend beyond reporting personal income, there’s a good chance an EIN will be part of the process.
What Info Do You Need Before Applying for an EIN?
Before you start the application process, it’s useful to have all of the necessary information on hand. Many delays occur because applicants start the process without having the proper details in place.
The IRS usually needs to know about your business and who is responsible for operating it. The person is called a responsible party.
You might need:
- Legal name of your business
- Trade name or “doing business as” name (if applicable)
- Business address
- Responsible party’s name and taxpayer identification number
- Business structure
- Reason for applying
- Expected number of employees
- Type of business activity
For example, if you are forming an LLC, you want to know whether it will be taxed as a single-member LLC, partnership, or corporation. Choosing the incorrect information during the application can lead to confusion down the line.
A little prep work in advance can turn a stressful government form into a simple checklist to complete. Nobody wants to have to stop halfway through an application because they suddenly realize they need information that’s missing.
How To Apply For An EIN Number Online?
The online application is the easiest and fastest option for most applicants. The IRS has an online system that takes you through the process step by step.
It usually takes this form:
Step 1: Check Your Eligibility
Before applying online, make sure your business qualifies for the IRS. A valid taxpayer identification number, such as a Social Security number or ITIN, is required unless specific exceptions apply to the applicant.
Step 2: Choose Your Business Type
The app will ask you what type of organization you are creating.
Popular choices:
- Sole proprietorship
- Limited liability company (LLC)
- Corporation
- Partnership
- Nonprofit organization
Selecting the proper structure helps the IRS understand your business obligations.
Step 3: Enter Business Details
You will enter your company information, including name, address, and responsible party information.
No rush here. A tiny misspelling of your legal business name or address can cause headaches when matching your records later.
Step 4: Apply And Receive Confirmation
In most cases, you can receive your EIN confirmation online immediately after submitting your application.
Keep this document in a safe place. If you lose your EIN confirmation letter, you could end up with unnecessary headaches when opening accounts or dealing with tax matters.
Other ways to request an EIN
The easiest way is generally to apply online, but the IRS provides other options for applicants who cannot use the online system.
Fax application
Businesses may also apply for an EIN by faxing Form SS-4. This is often used when online applications are not available or suitable.
Processing time can vary, but fax applications typically process faster than traditional mail.
Mail submissions
Mail applications should complete Form SS-4 and mail it to the correct IRS address. This way takes more time, so it is usually better for applicants who are not in a hurry.
Applicants from abroad
Foreign business owners can also apply for an EIN. They may have additional requirements because they may not have a U.S. Social Security number.
Knowing your circumstances before choosing an application method can help you avoid delays.
How Long Does It Take to Obtain an EIN?
How you file your application affects the processing time. Online applications are usually the fastest, as eligible applicants can receive confirmation of their EINs immediately after completing the process.
Applications by fax generally take longer, and applications by mail may take even longer because documents need to be processed manually. For a business owner, timing is critical in terms of opening a bank account, hiring employees or starting operations. And leaving it until the last minute can just add to the stress.
For example, a friend of mine once planned to start a small consulting business and thought the EIN process would take weeks. He found out about the option to apply online, filled out the application quickly and was able to go ahead and open his business account without any delay. Bottom line: It’s not what application you use, but how you prepare for it.

Common Errors When Applying for an EIN
Most EIN problems aren’t due to complex IRS rules. They occur when applicants hurry through the process.
Typical errors are:
- Applying multiple times unnecessarily
- Entering incorrect business information
- Choosing the wrong business structure
- Losing the EIN confirmation document
- Using outdated business details
- Confusing an EIN with a personal Social Security number
Another common mistake is thinking that every business automatically needs a new EIN with a change in ownership. Sometimes you use a new number; sometimes you use the same.
If you’re not sure, it’s a good idea to check out IRS guidance or speak to a qualified tax professional to help you make the right decision.
What to Do After You Get Your EIN
Obtaining your EIN is a big step, but it is only one piece of the puzzle to setting up a well-organized business.
When you have your number, you might want to:
- Open a business bank account
- Set up payroll systems
- Complete tax registrations
- Update business records
- Share your EIN with authorized financial partners
Your EIN is part of your business identity, so store it securely with other important documents.
Many entrepreneurs spend a lot of time thinking about launching products, finding customers, or creating marketing plans. Of course, those things are important. But little administrative things like organizing your taxes can make a big difference in the long run in terms of running your business.
EIN Number vs SSN: What’s the Difference?
An EIN and SSN are for different purposes. The Social Security number is used to identify a person, while an EIN is used to identify a business entity for tax purposes.
The main differences are:
| EIN | SSN |
| Used for business identification | Used for personal identification |
| Issued by the IRS | Issued for individuals |
| Helps manage business taxes | Used for personal tax reporting |
| Can be shared for approved business purposes | Should be protected as personal information |
For many entrepreneurs, using an EIN instead of a personal SSN for business activities adds another layer of organization and privacy.
