Vendor TIN Verification

Why TIN verification matters

Filing a 1099 with an incorrect TIN triggers IRS penalties: $60 per form if corrected within 30 days, up to $310 per form if not corrected. SKOOR verifies TINs before you file, catching mismatches early when they are free to fix.

How verification works

When a vendor submits a W-9 through the vendor portal or you enter a TIN manually, SKOOR runs an IRS TIN match. The system checks the combination of legal name and TIN against IRS records. Results come back as one of three statuses: Verified (name and TIN match), Mismatch (TIN exists but name does not match), or Not Found (TIN not in IRS records).

Handling mismatches

When a mismatch is detected, SKOOR automatically sends the vendor a request to update their W-9 with the correct legal name and TIN. The vendor receives a link to the portal where they can submit corrected information. SKOOR re-verifies automatically after the vendor updates their record.

Bulk verification

Run TIN verification across your entire vendor directory at once from the Vendor Management dashboard. SKOOR shows a summary of verified, mismatched, and unverified vendors. Filter by status to focus on vendors that need attention before 1099 filing season.

Impact on Business Health Score

TIN verification status is a compliance signal that feeds your Business Health Score. A high percentage of verified vendors strengthens Pillar 3: Business Credit. The SKOOR AI agent tracks verification rates and recommends action when verification coverage drops below 90%.
