What is a Tax ID?
A Tax ID Number which is also known as an Employer ID Number or Federal Tax Identification Number is a unique, nine-digit ID assigned by the Internal Revenue Service for tax purposes for businesses as well as Non-Profit organizations, Trusts and Estates. The Tax ID or EIN serves as a way to easily identify the entity similar to how a Social Security Number is used to uniquely identify individuals. While it is referred sometimes as an Employer ID Number the EIN is used by businesses and other entities to identify the tax accounts of both employers as well as other entities that have no employees.
