What Is an EIN and Does Your Business Need One?

When starting a business, one of the first tax-related terms you may encounter is EIN.

An Employer Identification Number helps the IRS identify businesses for federal tax purposes and is commonly used for payroll, tax filings, banking, and other business activities.

Not every business is required to have one, but many business owners benefit from obtaining an EIN even when it may not be strictly necessary.

What Is an EIN?

An Employer Identification Number (EIN) is a nine-digit federal tax identification number issued by the IRS.

Think of it as a federal identification number for your business. It is used on various tax filings and other financial documents associated with the company.

Unlike a Social Security number, an EIN is associated with the business rather than an individual taxpayer.

When Does a Business Need an EIN?

Whether an EIN is required depends on how the business is structured and operates.

A business may need an EIN in situations involving:

• Hiring employees

• Operating certain corporations or partnerships

• Filing certain federal tax returns

• Establishing certain retirement plans

• Meeting specific federal tax requirements

• Making particular business or tax elections

The requirements can vary, so business owners should determine what applies to their specific entity and circumstances.

Does an LLC Need an EIN?

Forming an LLC does not automatically answer whether you need an EIN.

For example, the federal tax treatment of a single-member LLC can differ from that of a multi-member LLC or an LLC that elects corporate taxation.

An LLC's number of owners, employees, and federal tax classification can all affect its EIN requirements.

Why Get an EIN Even If It Isn't Required?

Some businesses choose to obtain an EIN even when federal rules may not require one.

An EIN can be useful when:

• Opening a business bank account

• Establishing business financial accounts

• Working with certain vendors

• Completing business documentation

• Separating business and personal financial activity

• Preparing for future employees or business growth

Banks and other organizations may have their own requirements in addition to federal tax rules.

EINs and Hiring Employees

If your business hires employees, the EIN becomes an important part of your payroll and employment-tax setup.

It can be used when reporting wages, filing payroll tax returns, making applicable tax deposits, and preparing year-end employee forms.

This is why EIN setup is often handled alongside payroll and accounting setup when establishing a new business.

Is an EIN the Same as a Business License?

No. An EIN is a federal tax identification number.

Business licenses, state registrations, permits, and other requirements are separate and may depend on your location, industry, and business activities.

Obtaining an EIN therefore doesn't mean that every requirement for legally establishing or operating the business has been completed.

When Should You Apply for an EIN?

Businesses generally should establish their entity and determine the appropriate structure before completing tax registrations that depend on that structure.

Getting the sequence right can help prevent unnecessary complications with business records later.

A CPA can help you understand the tax considerations involved, while an attorney can provide guidance regarding legal entity formation and liability issues.
