The IRS sends CP2100 and CP2100A notices twice a year; an initial mailing in September and October and a second mailing in April of the following year. The notices inform payers that the information return is missing a Taxpayer Identification Number (TIN), has an incorrect name, or a combination of both.
Each notice has a list of payees, or the persons receiving certain types of income payments, with identified TIN issues. Payers need to compare the accounts listed on the notice with their account records and correct or update their records, if necessary. This can also include correcting backup withholding on payments made to payees.
The notices also inform payers that they are responsible for backup withholding. Payments reported on the information returns listed above are subject to backup withholding if:
- The payer does not have the payee’s TIN when making the reportable payments
- The payee does not certify their TIN as required for reportable interest, dividend, broker, and barter exchange accounts
- The IRS notifies the payer that the payee furnished an incorrect TIN and the payee does not certify their TIN as required
- The IRS notifies the payer to begin backup withholding because the payee did not report all their interest and dividends on their tax return
If you receive a CP2100 and/or a 2100A notice and you need guidance on responding to the IRS, contact R&A.
