Every year, businesses face expensive IRS penalties from mismatched Tax Identification Numbers (TINs). IRS TIN matching is your proactive defense.
Understanding B-Notices
CP2100/CP2100A notices hit when names and TINs don’t match IRS records. Consequences include backup withholding and per-form fines.
Why Most TIN Matching Falls Short
Free IRS tools have limits. Many services lack speed or integration.
