A single-member LLC can either use the Social Security Number (SSN) of the single member to conduct business, or it can obtain a separate Employer Identification Number (EIN). An EIN is required for a multi-member LLC, or if you anticipate having employees. The EIN will be the identifying number for your business, much like the Social Security Number is for an individual.
We recommend that you obtain an EIN number soon after the formation of your LLC whether you are forming a single-member or multi-member LLC. IncNow can assist with obtaining the EIN for United States residents and non-residents alike.
