An Employer Identification Number (EIN), sometimes referred to as an Federal Employer Identification Number (FEIN), is a number that is issued to a business so they can be identified more easily by the IRS when reporting taxes. This identifier is essential to any entity (corporation, limited liability company (LLC), partnership, limited partnership (LP), etc.) as it is required in order to successfully conduct financial transactions. Primarily this number is needed for hiring/paying employees and creating/opening a bank account under the entity’s name.
