Automate TIN Matching to Fight Fraud and IRS Penalties

Automated TIN matching is a legal requirement for any US business making payments to non-employee vendors. The IRS mandates a three-step compliance cycle for every vendor relationship:

Most companies skip step 2 and discover TIN errors only at step 3 — during 1099 filing season — when penalties are already being applied and vendor relationships are at risk.

Automated TIN matching is the real-time process of verifying a vendor’s Taxpayer Identification Number against official IRS records without manual intervention.

Unlike the IRS free batch system — which requires manual file uploads and 24–48 hour wait times — automated TIN matching validates TINs instantly at the point of vendor onboarding. Trustpair connects directly to IRS data sources, checks the TIN against the declared legal entity name, and returns one of five results: Match, No Match, Invalid, Checking, or Unconfirmed — all within seconds, inside your existing P2P workflow.

Real-time TIN matching is critical because TIN errors caught at vendor onboarding are easy to correct — TIN errors discovered at year-end trigger IRS penalties and are costly to fix.

The IRS imposes fines of $60 to $660 per incorrect 1099 form, with annual exposure reaching $4.09M for large businesses. Additionally, a 24% backup withholding rate applies to all payments linked to incorrect TINs.

Real-time TIN matching eliminates these risks by validating tax identities before any payment is approved — turning a reactive year-end scramble into a proactive automated control.

Trustpair provides instant, automated TIN verification embedded in your P2P workflow — the IRS free system requires manual batch file submissions and 24–48 hour processing times.

The IRS TIN matching program is a separate portal with no connection to your ERP or payment systems, making it impractical for ongoing vendor management.

Trustpair’s solution validates TINs in real time at vendor creation, returns granular results (including Invalid and Unconfirmed statuses not available from the IRS system), and combines TIN matching with bank account validation in a single automated workflow — with no integration work required.

Without automated TIN matching, businesses face IRS financial penalties, backup withholding on payments, and exposure to vendor impersonation fraud. Specifically:
  • Financial penalties: $60–$660 per incorrect 1099 form, up to $4.09M annually for large businesses
  • Backup withholding: The IRS automatically applies a 24% withholding rate on all payments associated with TIN errors
  • Fraud exposure: Mismatched TINs are a direct indicator of vendor impersonation — fraudsters use legitimate company names with unregistered tax IDs to divert payments
  • Operational cost: TIN corrections during 1099 season require weeks of AP team resources to chase vendors, refile forms, and respond to IRS notices

No — real-time TIN matching and bank account validation are two independent, complementary fraud prevention layers that work best together.

TIN matching confirms who a vendor is (legal entity identity vs. IRS records). Bank account validation confirms where to pay them (ownership of the declared payment account). Trustpair is the only platform combining both into a single automated verification workflow — delivering a three-way check of bank account, legal entity name, and IRS-registered TIN simultaneously.

Neither check replaces the other; together, they provide the most comprehensive vendor trust verification available to P2P teams today.
