What is

Form W-9


The Request for Taxpayer Identification Number and Certification is a form employers use to get information about taxpayer identification for freelancers who are US citizens and/or tax residents.

Form W-9 is a tax document used in the US to collect your Taxpayer Identification Number (TIN). It's needed when someone has to report certain financial transactions to the IRS. When asked, provide your name, address, and TIN or Social Security Number. This helps them prepare their tax forms, like Form 1099. Keeping your Form W-9 up-to-date ensures smooth tax reporting and compliance with the IRS.

Form W-9 is used for reporting various financial transactions to the IRS, including:

  • Income paid to you
  • Real estate transactions
  • Mortgage interest you paid
  • Acquisition or abandonment of secured property
  • Cancellation of debt
  • Contributions you made to an IRA
