Can two entities have the same EIN?

An Employer Identification Number (EIN) is a unique nine-digit number that every newly formed business needs to request. Only once the business is formed can it apply to the IRS for an EIN. This can be done online, by mail or phone and the EIN its issue is free.

The answer to if two business entities can have the same EIN depends on the structures of your two or more business entities. It also depends on how you want to protect the assets of your businesses. Generally, different business entities require different EIN’s.

However, if two companies share an EIN, then both companies are liable if one of the two is sued. That is the reason why most business owners prefer to request a separate one for each of their business entities.

One LLC can have multiple businesses under it. However, if the structure or ownership changes for any of the business entities, then they cannot use the same EIN. All businesses that are taxed differently need separate EINs.

Moreover, in some states, if a business opens in a second location it doesn’t need a new EIN. Whereas in other states, a new location must be separate from the current business. That would mean the new location will need a separate EIN.

It is always best to check the requirements with the state about permits, tax registrations, and licenses.

If there is a change to the name of a business but without a change in the structure, then it does not need a new EIN. However, the owner must submit a name change to the IRS. A business location address and mailing address can be changed without a change in EIN. This requires the submission of Form 8822 to the IRS.

An EIN can also be canceled if a business is discontinued.
