A W-9 Form is a federal tax document between a contractor or freelancer and a payer providing taxpayer identification information. It is used to report earnings to the IRS and ensure proper tax documentation for non-employees.
The W9 form IRS is officially called the "Request for Taxpayer Identification Number and Certification." With its help, people and organizations that have paid you get your correct taxpayer information so that they can properly file the necessary papers for the IRS.
The IRS form W9 does not involve paying taxes directly. It only helps businesses file the necessary tax documents later.
