Businesses face significant financial penalties and administrative burden from filing 1099 forms with mismatched TIN/name combinations, which are not caught until the IRS issues a B-notice months later.

IRS TIN Matching portal is free but painful for high volume and offers only basic matching; third-party tools like TINCheck work for batch but represent an extra step and cost, and there is no integrated solution that automates verification at onboarding or just before filing within the 1099 preparation workflow.
