Don’t let Delayed IRS Checks cause Compliance Risks

Every year, thousands of businesses receive B-Notices and face penalties because of invalid or mismatched TIN/Name combinations. If a payee’s Name/TIN doesn’t match IRS records, the IRS may send a CP2100/CP2100A ‘B-Notice,’ which can require you to begin backup withholding on future payments.

  • Verify TINs directly against IRS
  • Instantly validate data at onboarding or before filing.

Tailored for Every Industry

Eliminate TIN/name mismatches and verify TINs for payroll, lending, and tax reporting.
