If you change your name soon after you file your annual tax return, then you can inform the IRS of the EIN number change name through a signed notification, similar to a sole proprietorship. Once an EIN has been issued to an entity, it will not be reissued. If you only run one business entity, the IRS will only issue you a single EIN. You will be required to obtain a new EIN if a new LLC with more than one owner (Multi-member LLC) is formed under state law.
Starting a Business and EIN
You don’t need to register with city or county governments to start a business. If your business is an LLC, partnership, or nonprofit corporation, you must file for licenses and permits from the city or county. Business owners can submit a name change for their business. Whether you do business under your formal name or as a DBA, the rules for obtaining an EIN are the same.
Name Changes and IRS Notifications
A company can use a single EIN across units with multiple fictitious names, as long as those units aren’t separate legal businesses. Call the IRS to update your records.
Inform the IRS of EIN name changes through signed notification if you change your name after filing your tax return. Write to the IRS address where you filed your return. Visit the IRS Business Name Change page to see if you need a new EIN when changing your name. An authorized representative must sign the document.
Business owners can submit a name change for their business. To change an existing EIN, request a new EIN from the IRS. The IRS typically takes two months to register a business name change.
The name on the EIN should mirror the approved name with the Secretary of State. Make sure the EIN name fully reflects the official corporate name.
When you file a return, the EIN only has to match the name control, normally the first four name characters. A partnership only needs one EIN, not separate ones for each partner.
