TIN Matching Overview
What Is IRS TIN Matching?
IRS TIN Matching allows eligible payers and authorized agents to check whether a recipient’s name and Taxpayer Identification Number (TIN) combination matches IRS records before filing applicable
information returns.
With TaxBandits, you can verify recipient information through Bulk TIN Matching, review potential mismatches, and revalidate corrected records through supported workflows.

Why It Matters
Why IRS TIN Matching Matters for Tax Compliance
A TIN that doesn’t match IRS records turns into notices, withholding duties, and penalties.
IRS notices after you file
The IRS sends CP2100 or CP2100A notices for missing or mismatched TINs. Each flagged recipient needs follow-up from you.
B notices on a deadline
You must send a B notice within 15 business days. Recipients who don’t return a Form W-9 move toward backup withholding.
Backup withholding
at 24%
If a recipient doesn’t respond, you may have to withhold 24% of their payments, then deposit and report it on
Form 945.
Per-form penalties
Penalties for returns due in 2026 run $60 to $340 per return, depending on how fast you correct. Intentional disregard is $690.
Who It Helps
