Start Here: W‑9 Basics
What is a W‑9? A W‑9 is a form that vendors/contractors submit to you (the payer) so you can collect their legal name, address, and Taxpayer Identification Number (TIN: SSN or EIN). You use this info to prepare 1099s at year‑end.
Why it matters: Missing or incorrect W‑9s create last‑minute scrambling, compliance risk, and can trigger backup withholding obligations.

Who Needs to Collect a W‑9 (and When)
- When you onboard a U.S. vendor or independent contractor (before the first payment is best practice).
- When vendor details change (name, address, TIN, business structure).
- When the IRS notifies you of a TIN/name mismatch or that a payee is subject to backup withholding.

FAQs
Do I need a W‑9 from every vendor? If you pay a U.S. vendor/contractor reportable amounts, collect one during onboarding so you’re ready for 1099s.
Should a single‑member LLC put the owner’s name or the LLC name? It depends on how the LLC is taxed. See our guide: Disregarded Entity W‑9 Basics.
Can I store W‑9s in Google Drive? You can, but ensure access is restricted and data is encrypted. A purpose‑built system like GetW9 reduces risk and manual work.
What happens if I don’t have a W‑9 at payment time? You may be required to start backup withholding and keep records showing your attempts to obtain a valid form. Learn more: Backup Tax Withholding Guide
