How To Apply For And Get A Free Employer Identification Number From The IRS

An  Employer Identification Number (EIN) , also known as a Federal Employer Identification Number (FEIN), or Federal Tax Identification Number (FTIN), is like a Social Security number (SSN) for your business. The unique nine-digit EIN number allows the Internal Revenue Service (IRS) to identify businesses for tax reporting.

Keep reading our What is an EIN guide to find out if your business needs an EIN and learn how to  apply online, by telephone, fax, or mail  to get one for  free from the IRS website .

TIP: You should form your business before getting an Employer ID Number.   When you request your EIN number, you will be asked for the date of business formation and for the business's legal name.

Does My Business Need an EIN?

When does the IRS require an EIN number?

The  Internal Revenue Service (IRS)  has specific, established rules that determine when you need to apply for an EIN for your business.

If any of the following statements are true, you'll need to get an EIN:

Your business has employees Your business is a  partnership  or  corporation Your business files excise taxes Your business withholds taxes for nonwage income paid to a nonresident alien

All businesses can benefit from having an EIN. Visit our  EIN Benefits  guide to learn more.

Sole Proprietorship

If your business structure is a sole proprietorship without employees (and doesn’t file any excise or pension plan tax returns), then you are not required to get an Employer Identification Number (EIN).

Sole proprietors with employees are required to have an EIN.

A sole proprietor who is hiring employees should start thinking about when to form an LLC. Our sole proprietorship to LLC guide can help you decide when to take the next step in growing your business.

It's recommended that taxpayers get an EIN number in order to open a business bank account, build business credit , and lower the risk of identity theft.

Learn more about EINs for Sole Proprietorships .

Single-Member LLC

If your business entity is a single-member LLC without employees (or excise tax liability), then you are not required to get an Employer ID Number.

Single-member LLCs are required to have an EIN if they have employees.

It’s still recommended (and sometimes required) to open a bank account, to hire employees later, and in order to maintain your corporate veil.

Learn more about EINs for Single-Member LLCs .

Multi-Member LLC or Partnerships

If your business structure is a partnership or multi-member LLC, you  are required to get an EIN number because the LLC must file a partnership return  and provide  K-1s to members of the LLC.

Learn more about EINs for LLCs .


If you have an S corporation tax structure, you are required to have an EIN for tax reporting purposes.

If you have a C corporation, your business is viewed as a separate entity and you are required to get an EIN for tax reporting purposes.

Nonprofit Organizations

If your business structure is a nonprofit, you are required to have an Employer ID Number for tax reporting purposes.

Trusts and Estates

EINs are used for specific types of trusts and estates under varying circumstances.

Request An EIN

You can visit the online IRS  EIN Assistant  website and follow their step-by-step application process as soon as your business is officially formed. The EIN Assistant provides questions and answers, but we've also  simplified the steps  below.

You must  form your business before getting an EIN. The IRS will ask for your business formation date and legal business name. You will need to register your business and get approval for the business's name from your state before getting an EIN. Visit our LLC before EIN guide to learn more.

For help with business formation, visit our free  Form an LLC  or  Form a Corporation  guides for step-by-step instructions.

If you are undecided on what business structure to choose, visit our How To Choose a Business Structure guide or our LLC vs Sole Proprietor guide.


IRS EIN Applicant Requirements: "All EIN applications (mail, fax, electronic) must disclose the name and Taxpayer Identification Number (SSN, ITIN, or EIN) of the true principal officer, general partner, grantor, owner or trustor. This individual or entity, which the IRS will call the 'responsible party', controls, manages, or directs the applicant entity and the disposition of its funds and assets. Unless the applicant is a government entity, the responsible party must be an individual (i.e., a natural person), not an entity."

Recommended:  You can request and receive a free EIN from the IRS directly by using the online  EIN Assistant .

Why Should A Business Get an EIN?

No matter what kind of business you have, it is usually a good idea to get an EIN number. Here are some advantages of having an EIN:

Most banks require an EIN in order to open a business banking account.

A business bank account will simplify the process of tracking and managing your professional expenses. You can also build business credit and qualify for more  loans .

Learn more about why you need a business bank account  and visit our  best banks for small business  review.

You need an EIN to get a business credit card.

An EIN acts like a Social Security number for a business. Banks use EINs to approve you for a business credit card.  A business credit card is a great way to start building your business credit and acquire larger and more lines of credit down the road.  Most new businesses have a difficult time getting approved for a business credit card, but some credit card companies like Divvy approve even new businesses.

Recommended: Visit Divvy to apply for their business credit card, earn points, and build your business credit quickly.

Apply With Divvy

You will need an EIN before you can hire employees.

Employees will file their taxes separately under the LLC’s 1040 form. Employers need an EIN for an LLC to set up payroll, and the IRS will use the business’s EIN to track payroll taxes for taxpayers. An EIN number is necessary to register for your State's employer taxes.

If you’re an LLC, an EIN helps you  maintain your corporate veil .

The corporate veil protects business owners from personal liability for the business’s debts. Maintaining the corporate veil also establishes credibility and professionalism by allowing your business to have its own identity separate from its owners. 

An EIN will help to prevent identity theft.

Your Social Security number (SSN) will be more private. It’s less likely for someone to break into your accounts when you keep business finances and personal finances separate.
