Request for Taxpayer Identification Number and Certification

Purpose of Form W-9

Give Form W-9 to the requester to provide your correct TIN and to avoid backup withholding. Complete this form if you are a U.S. person (including a resident alien).

Form W-9 is used by U.S. persons (including resident aliens) to provide their correct Taxpayer Identification Number (TIN) to payers required to file information returns with the IRS.

The requester uses Form W-9 to report to the IRS:

  • 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

If you don't provide your TIN, you might be subject to backup withholding.
