TIN vs. EIN: What new business owners need to know before they accept their first payment
A TIN is any tax identification number used for U.S. tax reporting, such as an SSN (social security number), ITIN (individual tax identification number), or EIN (employer identification number). An EIN is a specific type of TIN issued by the IRS (Internal Revenue Service) to identify a business and is often needed for banking, hiring, and payment setup.
