Do you need an EIN for an LLC? The answer to this question depends upon various factors, like the number of owners your LLC has, taxation treatment it elects, and the characteristics it possesses.

Does an LLC Need an EIN?

An EIN or an Employer Identification number is a unique nine-digit number for business entities just like a Social Security number (SSN) for individuals. The Internal Revenue Service (IRS) assigns the EIN to a business entity.

Business entities must quote their EIN on their tax returns just like individuals mention their SSN. An EIN is like an account number on the basis of which the IRS identifies businesses for the purpose of taxation.

A Limited Liability Company (LLC) is a new type of business entity compared to corporations and other business structures. Since an LLC is a state entity, its formation and functioning may be different in different states.

Since the IRS does not classify LLCs as a separate taxable entity, you may have to get an EIN for your LLC in some cases. Whether you need an EIN for your LLC, or you can use something else for tax identification, depends upon various factors like how many owners it has and what characteristics it possesses.

Single Member LLC

The owners of an LLC are called members. You may or may not be required to have an EIN for a single member LLC.

If your LLC is engaged in a home-based business, and you look after the business on your own without hiring any employees, then you need not have an EIN. You can elect to be treated as a sole proprietorship for tax purposes, and use your SSN instead of the EIN for your LLC.

If you pay pension or excise tax, you must apply for an EIN.

Single Member LLC With Employees

If you want to hire employees, you must get an EIN for your single member LLC. Earlier on, a single member LLC could use its owner's SSN for payroll taxes. However since 2009, it must use an EIN for filing payroll tax returns.

Taxation Election


If there is a change in the ownership structure, you may need to have a new EIN for your LLC. When an LLC is sold, the new owners must apply for a new EIN. For instance, if a single member LLC was filing its tax returns as a sole proprietorship and it later on elects to file as a corporation, then you need to get a new EIN.

An LLC must use an EIN for paying excise taxes to the Bureau of Alcohol, Tobacco, Firearms, and Explosives. You must have an EIN if your LLC participates in a Keogh retirement plan or withholds income tax on non-wage payments made to a nonresident alien.

Even if your single member LLC is not required to have an EIN, you may still want to get one so that you don't have to use your SSN while filing tax returns.

Getting an EIN

The most preferred way of getting an EIN is to apply online. Your information is validated and you get an EIN almost instantly. All business entities with their principal office located in the U.S., or having their legal residence in the U.S., can apply online.
