The primary difference between a Federal Tax ID and an Employer Identification Number (EIN) is that a Tax ID is used to identify people who can be taxed within the United States, while the EIN is used to identify companies. Both the Tax ID and EIN are nine-digit numbers used for tax purposes, but they serve different purposes and are issued at different levels of government.

  • Federal Tax ID (TIN): A Taxpayer Identification Number (TIN) is a generic term for a tax identification number, which can be issued on the state or federal level. It is used to identify individuals, sole proprietors, corporations, partnerships, nonprofit associations, trusts, estates of decedents, government agencies, and other business entities. A Social Security Number (SSN) is an example of a TIN for individuals.
  • Employer Identification Number (EIN): An EIN is a type of TIN that is specifically assigned to businesses. It is used to identify a business entity and is issued by the Internal Revenue Service (IRS) at the federal level. EINs are required for various business tax purposes, such as filing taxes or hiring employees.

In summary, a TIN is a broader term that can be issued on either the state or federal level, while an EIN is a specific type of TIN issued by the IRS to identify businesses at the federal level.
