What is a W-9 Form?

The W-9 form is a standard IRS document required whenever a freelancer, an independent contractor, or a vendor needs to provide their taxpayer identification number (TIN) to an entity or individual from whom they receive payments for services rendered or for other income-generating activities. The purpose of the W-9 form is manifold:

  • Verification of Taxpayer Information: It ensures that the payers have the correct information to report income paid to the IRS.
  • Prevention of Backup Withholding: It helps individuals avoid backup withholding. If a payer does not have your TIN, they are obliged to withhold a portion of your payment and send it to the IRS.
  • Components of the W-9 Form: The form requires basic information, including the name of the individual or entity, their TIN (which could be a Social Security Number or an Employer Identification Number), and the type of entity they are (e.g., individual, corporation, partnership).
