What is TIN Matching, and why is it important before filing 1099 or W-2 forms?

TIN Matching is a service provided by the IRS that verifies whether the Taxpayer Identification Number (TIN) and name combination entered for a recipient matches IRS records. 

TaxBandits offers a built-in TIN Matching service that helps you validate recipients’ TIN/name combinations before filing 1099/W-2 for them.

Why this matters

If a TIN and name combination doesn’t match IRS records, your form may be rejected or trigger a CP2100/CP2100A notice (commonly known as a B Notice). This can result in penalties and require follow-up communication with recipients to correct the issue.

Running TIN Matching before filing helps you avoid these problems by identifying and correcting mismatches in advance
