What is the CP2100A notice?
The CP2100A Notice is a communication from the IRS alerting payers that one or more of their information returns, such as Form 1099, contain TIN discrepancies. These discrepancies fall into three main categories:
- Missing TINs: The taxpayer identification number is absent on the return.
- Incorrect TINs: The provided TIN is invalid or improperly formatted.
- Name/TIN mismatches: The name and TIN combination does not match IRS records.

What’s the difference between a CP2100 and CP2100A notice?
Both CP2100 and CP2100A Notices address TIN issues, but the primary difference lies in the volume of errors:
- CP2100 Notice: Sent to payers with 50 or more TIN discrepancies.
- CP2100A Notice: Sent to payers with fewer than 50 TIN discrepancies.
Pro Tip
Use the IRS TIN matching program to verify payee TINs before filing Form 1099s. This step helps you catch errors early and avoid receiving a CP2100A notice.
Common reasons for receiving a CP2100A notice
There are several reasons why a payer may receive a CP2100A Notice. These include:
- Data entry errors: Mistakes made during manual or electronic entry of TINs or names.
- Outdated information: Payee details that have not been updated to reflect changes, such as name changes due to marriage.
- Incomplete forms: Submitting forms with missing or incomplete TINs.
- IRS or payee errors: Issues in IRS processing or incorrect information provided by the payee.
What to do when you receive a CP2100A notice
When you receive a CP2100A Notice, taking prompt and appropriate action is crucial. Follow these steps:
- Review the notice: Carefully read the notice and examine the list of payees with TIN discrepancies.
- Compare with internal records: Cross-check the IRS-provided list with your own payee records to confirm errors.
- Initiate backup withholding: If a payee’s TIN is missing or clearly incorrect, begin backup withholding immediately.
- Send “B” notices: For mismatched TINs, issue the appropriate “B” Notice to request corrected information from the payee.
- Update records: Correct any discrepancies in your internal files based on the payee’s response.
Backup withholding and its importance
Backup withholding is a critical component of the IRS’s process for ensuring accurate tax reporting. If a payee fails to provide a valid TIN or provides incorrect information, the payer is required to withhold a percentage of the payment—currently 24%—and remit it to the IRS. Here’s how it works:
- When to begin: Initiate backup withholding immediately if a TIN is missing, invalid, or if the payee fails to respond to a “B” Notice.
- How to calculate: The 24% withholding is applied to reportable payments, such as interest, dividends, or nonemployee compensation.
- Reporting: Backup withholding amounts must be reported to the IRS on Form 945, Annual Return of Withheld Federal Income Tax.

Pro Tip
Maintain accurate and up-to-date payee records by requesting updates annually. This reduces the likelihood of mismatches or missing TINs.
How to avoid future CP2100A notices
To reduce the likelihood of receiving future CP2100A Notices, consider implementing the following best practices:
- Use IRS TIN matching program: Verify payee TINs against IRS records before submitting information returns.
- Maintain updated records: Regularly update payee information to reflect changes in names, addresses, or TINs.
- Train staff: Ensure that employees responsible for filing information returns are knowledgeable about proper procedures.
- Double-check entries: Review all forms for accuracy before submission to minimize errors.
Proactive measures can help streamline your reporting processes and avoid unnecessary complications.
Consequences of ignoring a CP2100A notice
Failing to address a CP2100A notice can lead to several serious consequences, impacting both your business operations and financial standing. Understanding these potential outcomes is essential to emphasize the importance of timely action.
- IRS penalties: Ignoring the notice can result in penalties for failing to file accurate information returns. These fines can accumulate quickly if the errors remain unaddressed.
- Backup withholding liability: If you fail to initiate backup withholding for payments associated with missing or incorrect TINs, you may be held liable for the uncollected withholding amount, along with added penalties and interest.
- Increased IRS scrutiny: Non-compliance with IRS regulations can draw heightened attention to your business filings, potentially leading to audits or further investigation.
- Unresolved payment delays: Payees with TIN discrepancies may experience payment delays, which can strain your relationships with contractors, vendors, or other recipients.
- Reputational damage: Prolonged errors or non-compliance can harm your reputation as a responsible payer, affecting your credibility with both the IRS and your payees.
Pro Tip
Respond promptly to any CP2100A notice to avoid penalties and interruptions to your business operations. Delay could lead to increased IRS scrutiny.
Seeking professional help
Managing the complexities of a CP2100A notice can be overwhelming, especially for businesses with numerous payees or limited familiarity with IRS procedures. Seeking professional assistance can streamline the resolution process and prevent costly errors.
- Certified tax professionals: CPAs, enrolled agents, and tax attorneys can help you understand the notice, address discrepancies, and respond correctly. Their expertise ensures that your responses comply with IRS guidelines.

Frequently asked questions
What payments are subject to backup withholding?
Backup withholding applies to certain payments when a payee fails to provide a valid TIN or provides incorrect information. These payments include interest, dividends, nonemployee compensation, rent, royalties, and other reportable income. Payers must withhold 24% of the payment amount and remit it to the IRS if required.
Can I avoid sending “B” notices if the payee corrects their information?
If the payee provides updated and accurate TIN information before you send a “B” Notice, you may not need to issue it. However, you must ensure that the corrected information resolves the discrepancy and is updated in your records. If there’s doubt about the accuracy, sending a “B” Notice is recommended.
What should I do if I find errors in my submitted Form 1099s?
If you discover errors in the information returns you’ve already submitted, you should file corrected forms with the IRS as soon as possible. This includes fixing incorrect TINs, payee names, or other discrepancies. Be sure to mark the corrected forms clearly as “Corrected” to avoid duplication.
Do I need to inform the IRS about updated payee information?
No, you do not need to notify the IRS directly about updated payee information. Instead, update your internal records to ensure that future filings are accurate. The IRS will recognize the corrected TINs or names in your next filing cycle.
How can I verify TINs to prevent future CP2100A notices?
The IRS offers a TIN matching program that allows payers to verify payee TINs against IRS records before submitting information returns. Using this program helps identify discrepancies early, reducing the risk of receiving CP2100A Notices. Regularly verifying TINs is a best practice for compliance.
