IRS Backup Withholding Management
Form 945, CP2100 Notices & 24% Withholding
Handling Form 945, CP2100 notices, and 24% tax withholding compliance for missing or incorrect Taxpayer Identification Numbers (TINs) and EINs.
Understanding Backup Withholding Compliance
Backup withholding requires a payer to withhold 24% of certain payments, such as interest, dividends, and contractor payments, and remit it to the IRS. It is typically triggered when a payee fails to furnish a correct Taxpayer Identification Number (TIN) or when the IRS notifies you of a name/TIN mismatch through a CP2100 notice.
QuickTaxnBooks manages the full backup withholding lifecycle: we review your CP2100 notice, identify affected payees, prepare the required first and second B-Notices, collect corrected W-9s, and file Form 945 to report all withheld amounts. We also reconcile your federal tax deposits so your records match the IRS, preventing costly failure-to-deposit penalties.

What You Receive
Frequently Asked Questions
Why did I receive a CP2100 notice?+
The IRS sends CP2100 notices when the name and TIN on your filed 1099 forms do not match IRS records. It lists payees subject to backup withholding and tells you to begin or continue withholding 24%.
How do I stop backup withholding?+
Obtain a corrected W-9 from the payee with the right TIN. For a second B-Notice within three years, the payee may also need to certify with the IRS. Once corrected, withholding can stop.
