The IRS Form W-9, officially titled Request for Taxpayer Identification Number and Certification, is the cornerstone document for anyone who receives income that must be reported to the Internal Revenue Service. Whether you’re an independent contractor, freelancer, vendor, or a business entity, a correctly completed W-9 ensures accurate tax reporting and helps you avoid backup withholding.
The W-9 collects your legal name, business name (if applicable), address, and Taxpayer Identification Number (TIN). The TIN can be a Social Security Number (SSN) for individuals or an Employer Identification Number (EIN) for businesses. The form also includes a certification section where you attest that the information is correct.

You must provide a W-9 whenever a payer will report payments to you on Form 1099‑NEC or 1099‑INT. Typical scenarios include:
If the payer does not receive a completed W-9, they are required to withhold 24% of the payment as backup withholding.
