Starting a business is an exciting step for aspiring entrepreneurs and small business owners. But before you can officially open your doors, one key requirement from the IRS is obtaining a Federal Employer Identification Number (EIN). Whether you plan to hire employees, open a business bank account, or register your company, the EIN is a vital piece of your business foundation.
If you’re applying for an EIN for the first time, this guide will walk you through what it is, why you need it, and how to apply with confidence.
What is a Federal Employer Identification Number (EIN)?
A Federal Employer Identification Number, also called a Tax ID number, is a unique nine-digit number issued by the Internal Revenue Service (IRS) to identify your business for tax purposes. Think of it as a Social Security number for your company.
Businesses of all types—LLCs, corporations, partnerships, and even sole proprietorships—often need an EIN to comply with federal and state regulations.
Why Do You Need an EIN?
Many first-time business owners wonder whether an EIN is truly necessary. Here are the most common reasons you’ll need one:
- Hiring Employees – If you plan to hire staff, the IRS requires you to have an EIN.
- Opening a Business Bank Account – Most banks won’t let you open a dedicated business account without an EIN.
- Filing Business Taxes – An EIN is necessary for federal and sometimes state tax filings.
- Establishing Business Credit – If you want to build credit in your company’s name, you’ll need an EIN.
- Separating Personal and Business Finances – Even for sole proprietors, having an EIN helps maintain a professional business identity.
Who Should Apply for an EIN?
You should apply for an EIN if you are:
- Forming a new LLC, Corporation, or Partnership
- Operating as a sole proprietor but plan to hire employees or open a business bank account
- Starting a nonprofit organization
- Creating a trust or estate
- Looking to establish business credit

Applying for an EIN is not as complicated as it may seem, but it’s easy to feel overwhelmed when navigating government forms for the first time. Here’s what to expect:
- Determine Eligibility – You must have a valid Taxpayer Identification Number (such as an SSN or ITIN) to apply.
