W-9 readiness guide
Contractor Won't Provide W-9
When a contractor will not provide a W-9, treat it as a controlled follow-up workflow. Confirm the vendor contact, resend a clear secure request, document each attempt, and route the record to firm review before any payment-process or reporting decision. The IRS Form W-9 sources linked below explain the form context. This page is operations guidance, not tax or legal advice.
Who this page is for
This page is for accounting staff and firm owners who need a consistent process when a vendor does not respond to W-9 requests. It is designed for internal cleanup queues, not for telling a contractor what their legal obligations are.
Main answer
Start with clean records and calm follow-up. Verify the vendor email, resend through a secure request flow, keep a concise activity trail, and assign the record to the right reviewer. Avoid putting TINs, request tokens, or private document links in free-form notes or email bodies.
The IRS describes Form W-9 as a request for taxpayer identification number and certification, and the current form and requester instructions are linked in the sources. Use those official materials for form context and your firm process for any reporting or payment next steps.
Decision workflow
- Check whether the vendor is truly missing a W-9 or whether a document was uploaded under another vendor record.
- Confirm the recipient email and resend a clear request with a secure upload link.
- If the request bounces or the vendor declines, record the safe status and stop duplicate same-day outreach.
- Escalate the vendor to the owner or reviewer responsible for firm policy decisions.
- Keep standard exports and client-facing status views focused on safe fields until review is complete.
Checklist
| Step | Action | Reason |
|---|---|---|
| Confirm | Check that the vendor contact, client context, and request email are correct. | Prevents follow-up on a bad address or unclear vendor record. |
| Resend safely | Send one clear request through the approved secure channel. | Keeps the vendor action simple and avoids TINs in email. |
| Document | Record request attempts, bounce status, and vendor responses. | Gives the firm a review trail without storing sensitive notes. |
| Escalate | Route the vendor to the owner or designated reviewer. | Keeps reporting and payment-process decisions out of ad hoc staff messages. |
| Review exports | Use standard exports and avoid full-TIN access unless explicitly approved. | Reduces sensitive-data exposure during cleanup. |

FAQ
What should I do first when a contractor will not provide a W-9?
Document the request, confirm the contact information, resend through an approved secure workflow, and route the record to firm review before making reporting or payment-process decisions.
Should I ask for a TIN by email?
Avoid collecting SSNs or EINs in email. Use a private upload workflow or another firm-approved secure method for sensitive tax documents.
Can W9Finder force a contractor to respond?
W9Finder cannot force a response. It helps firms track requests, reminders, upload status, review issues, and exports so the team has a cleaner record of follow-up.
