Cross-reference taxpayer identification numbers against IRS records before you file — eliminate B-Notices, penalties, and returned mail at $0.49 per check.
The IRS issues a CP2100 or B-Notice every time a TIN/name combination on a filed information return doesn't match their records. Each mismatch can trigger penalties up to $290 per form — and backup withholding requirements on future payments.
TIN Matching lets you catch these discrepancies before you file, not after.
B-Notice / CP2100
Triggered when TIN/name on filed return doesn't match IRS records. Requires backup withholding at 24%.
Penalty Per Form
Up to $290 per incorrect return filed with a wrong TIN — multiplied across every mismatched recipient.
TIN Match Prevents It
At $0.49 per check, a single avoided penalty pays for 590 verifications. The math is simple.
