I have an EIN/DBA (DBA expired) from a previous business that never really became a business. It managed to generate a very small revenue last year and quite honestly cost me more than that. Now, I am in the process of trying to open a retail store as a new business. Will I need to cancel or close out the old EIN? I read somewhere that the EIN stays and I can have one EIN for more than one business. Can some one point me in the right direction to clear this up? I plan to incorporate the new business as an LLC.
