IRS TIN/Name Matching
Real-Time IRS TIN Validation for Clean 1099s
IRS TIN Matching helps payers verify that the taxpayer name + TIN (SSN or EIN) on file matches official IRS records — in real time.
Prevent downstream filing errors, reduce penalty exposure, and keep vendor records audit-ready.
What is IRS TIN/Name Matching?
IRS TIN Matching enables businesses and other payers to confirm that the TIN and legal name they have on file matches the IRS’s records. It’s a critical step for accurate information reporting and year-round vendor compliance.
Why It Matters
Incorrect TIN reporting can trigger avoidable headaches and exposure:
CP2100 B-Notices
Mismatches often lead to notices and repeat remediation cycles.
972CG Penalty Risk
Incorrect 1099 data can contribute to penalty assessments and defense work.
Backup Withholding
Unresolved mismatches can create withholding requirements and vendor friction.
Vendor Data Integrity
Bad master data causes reporting errors, payment issues, and audit noise.
