Why You Need W-9s From Vendors

Before paying a vendor $600 or more in a calendar year, your business must collect their W-9 to report payments on Form 1099-NEC or 1099-MISC.

Failing to collect W-9s can result in IRS penalties, backup withholding requirements, and complications during tax season.

When to Request a Vendor W-9

  • New vendor onboarding – Request before first payment
  • Annual verification – Confirm information is current
  • Information changes – When vendor updates their business structure
  • Missing records – When preparing 1099s and W-9 is not on file

Vendor W-9 Best Practices

  • Request W-9 before issuing first payment
  • Store W-9s securely for at least 4 years
  • Verify TIN matches IRS records to avoid B-notices
  • Track which vendors have submitted and which are pending
  • Send reminders for incomplete submissions
