W-9 Form

A W-9 Form is an Internal Revenue Service (IRS) tax form used in the United States to request the taxpayer identification number (TIN) of a person or entity that is required to report income to the IRS. The W-9 Form is typically provided by a payee, such as a freelancer, independent contractor, or vendor, to the payer (employer or client) who is responsible for reporting payments made to the IRS.
