What is an EIN? (& How to Get One)

author-image by Andrey Doichev Updated: August 2, 2024

Starting a business involves navigating various legal and financial requirements, and one crucial step is obtaining an Employer Identification Number (EIN). This unique identifier, often called a business tax ID, is essential for most companies operating in the United States. 

Whether you’re a limited liability company (LLC), sole proprietor, corporation, or nonprofit organization, understanding what an EIN is and how to acquire one is vital for your business’s compliance and growth. This article will demystify the EIN, explain its importance, and guide you through the simple process of obtaining one for your business.

What is an EIN? 

An EIN is a nine-digit number obtained from the Internal Revenue Service (IRS). This number operates similarly to a social security number (SSN) but for your business. An EIN is primarily used for tax purposes and to identify businesses in their dealings with the government and other organizations, however, there are several benefits to obtaining an EIN for your business as well. 

Importance of EIN for New Business Owners

For new business owners, obtaining an EIN is a crucial step in establishing their business. Additionally, Having an EIN can offer numerous advantages for businesses, both financially and legally. Here are some key reasons why an EIN is important:

Obtaining a Business License 

Having an EIN often impacts getting a business license because many local and state governments require it as part of the licensing process. This is because an EIN demonstrates that you’ve registered with the federal government, which can be a prerequisite for obtaining various permits and licenses needed to operate legally in your area.

Establishing Business Credit 

With an EIN, businesses can establish their credit profile, making it easier to secure loans, leases, and other financial products. This is particularly beneficial for new businesses looking to open a business line of credit or secure business credit cards. 

Opening a Business Bank Account 

Many banks require an EIN to open a business bank account. This not only helps in managing business finances more effectively but also ensures your personal assets remain separate from your business assets, protecting your personal liability. 

Hiring Employees 

For businesses with employees, an EIN is necessary for payroll processing and tax reporting, ensuring compliance with federal regulations and helps in managing employee-related taxes. 

EIN for Different Types of Businesses

Different business structures have specific requirements for obtaining an EIN. Here’s a breakdown:

  • Sole Proprietorships: Sole proprietors without employees or excise tax filings may not need an EIN. However, if they hire employees or file excise taxes, they must obtain one 
  • Partnerships: All partnerships are required to have an EIN, regardless of whether they have employees 
  • Corporations: Corporations must have an EIN for tax filing and reporting purposes, even if they do not have employees
  • Limited Liability Companies (LLCs): Multi-member LLCs need an EIN. Single-member LLCs need an EIN if they have employees or if they choose to be taxed as a corporation. 
  • Nonprofits: Nonprofits must have an EIN to apply for tax-exempt status and to file annual information returns

How to Apply for an EIN

Obtaining an EIN through the IRS is easy and free. There are three main ways to obtain an EIN:

  • Online: Apply through the IRS website, which is the fastest method.
  • By Mail: Complete Form SS-4 and mail it to the IRS.
  • By Fax: Fill out Form SS-4 and fax it to the IRS.

The online method typically provides an EIN immediately, while mail and fax can take several weeks. Most businesses can apply online, but there are some restrictions (e.g., international applicants must use mail or fax). Fortunately, the process is free regardless of the method chosen.

What to Prepare for an EIN Application

When applying for an EIN, provide the following information about your business:

  • The business entity’s legal name and any trade name it operates under
  • The business’s mailing address
  • The business’s start date 
  • The business’s industry 
  • The business’s legal structure (e.g., sole proprietorship, partnership, corporation) 
  • The reason for applying for an EIN (e.g., starting a new business, hiring employees) 

Tips for Managing Your EIN

Once you have your EIN, you will need to manage it to ensure your business maintains compliance and is able to complete necessary actions such as opening a business bank account. 

What to Do If You Lose Your EIN

If you lose your EIN, there are several steps you can take to retrieve it:

  • Check your business documents, both physical and digital, for previously filed tax returns or the confirmation letter you received when you first applied for your EIN
  • Contact the IRS Business & Specialty Tax Line at 800-829-4933 and provide identifying information about your business
  • Reach out to your bank or the agency that issued your business license, as they may have your EIN on record

When You Need to Apply for a New EIN

There are specific circumstances under which you will need to apply for a new EIN:

  • If your business structure changes, such as from a sole proprietorship to a corporation or partnership, you will need a new EIN
  • If your business is subject to bankruptcy proceedings, you will need to obtain a new EIN
  • If you incorporate your business, even if you were previously operating as a sole proprietorship or partnership, you will need a new EIN
  • If you end an old partnership and begin a new one, a new EIN is required to ensure the new entity is correctly identified for tax purposes

Frequently Asked Questions

How Much Does it Cost to Get an EIN?

Obtaining an Employer Identification Number (EIN) from the IRS is free of charge. You can apply for an EIN online, by fax, or by mail without incurring any fees. The IRS provides this service at no cost to ensure that all businesses, regardless of size, can comply with federal tax regulations.

Yes, self-employed individuals can use an EIN. While sole proprietors and single-member LLCs are not required to have an EIN if they do not have employees, many choose to obtain one. Using an EIN instead of a Social Security Number (SSN) can help protect against identity theft and is often required for opening business bank accounts, applying for business licenses, and filing certain tax returns.

The time it takes to get an EIN depends on the method of application:

  • Online Application: You can receive your EIN immediately upon completion of the online application, which typically takes about 15 minutes.
  • Fax Application: If you fax your completed Form SS-4, you will receive your EIN within about one week.
  • Mail Application: If you mail your application, it generally takes about four weeks to receive your EIN.

I launched my first small business in 2015. I loved airsoft, so I created a small website where I would go on to educate parents about the sport and help them buy the safest gear for their kids. Since then, I have started many similar ventures, educating millions of people on topics including entrepreneurship, marketing, website development and online privacy.
