Why W-9 Management Matters

Missing or incorrect W-9s can lead to:

TIN Mismatches

Incorrect name/TIN data triggers IRS mismatch notices.

972CG Penalty Exposure

Inaccurate filings increase penalty risk.

Backup Withholding Risk

Unresolved documentation gaps may require withholding.

Audit Gaps

Incomplete documentation complicates compliance reviews.


W-9 Compliance Workflow

TIN Comply connects outreach, document collection, IRS validation, and correction into a single automated compliance loop.

Step 1
Trigger W-9 Request

Upload a vendor file or initiate outreach directly from a failed TIN/Name validation.

Step 2
Secure Invitation

Vendor email is entered manually or pulled from your file. A secure request is automatically delivered.

Step 3
Digital Completion

Vendors complete and digitally sign the W-9 through a secure portal — no PDFs or manual chasing.

Step 4
IRS Validation

Submitted name and TIN data is instantly validated against official IRS records.

Step 5
Correction Loop

If validation fails, the vendor is automatically notified to correct the information.

Step 6
Audit-Ready Storage

Approved W-9s are securely stored, logged, and available for review or download.
