Why You Might Receive an IRS Notice
The IRS sends notices for a variety of reasons, including:
- Missing or incorrect information on your Form 1040
- Discrepancies between reported income and what third parties report (W-2s, 1099s)
- Outstanding tax balances
- Eligibility questions about credits or deductions
- Verification of identity or filing status
- Notification of a refund delay or adjustment
Common IRS Notices for 1040 Filers
CP2000 – Underreported Income
This notice indicates a mismatch between your Form 1040 and third-party forms like W-2s and 1099s. It’s not a formal audit but a proposed adjustment. You can accept the changes or respond with evidence to support your original return.
Letter 5071C – Identity Verification
This letter asks you to confirm your identity because the IRS suspects identity theft. You’ll need to verify your identity online or by phone before your return is processed.
Letter 12C – Missing Documentation
This letter typically requests additional documents to support items on your 1040 return, such as Form 8962 for premium tax credits or proof of deductions.
CP14 – Balance Due Notice
This is a formal notice that you owe taxes to the IRS. It includes the amount due, due date, and how to make payment or set up a payment plan.
CP11 – Return Adjustment
This notice means the IRS has made changes to your return and you now owe more tax. It usually results from a math error or unreported income.
CP88 – Delinquent Return Hold
This notice means the IRS is holding your refund until you file one or more past-due tax returns. You’ll need to take quick action to avoid losing your refund.

How to Respond to an IRS Notice
- Read the notice carefully: Understand the issue raised, whether it’s a request for documents, a proposed change, or a balance due.
- Check for accuracy: Match the IRS claim with your original tax return and supporting documents.
- Gather documentation: Compile relevant forms, receipts, or employer statements as needed.
- Respond promptly: Many notices have a 30-day deadline. Delays can result in penalties.
- Use IRS contact details: If a phone call or fax is necessary, use the numbers provided on the notice.
Should You Amend Your Return?
If you realize there was an actual mistake on your filed Form 1040, you may need to file Form 1040-X to correct it. However, if you disagree with the notice and have documentation to prove your claim, you should respond to the IRS directly rather than file an amended return immediately.
PEAK Business Consultancy Services can review IRS correspondence, determine whether a correction or amended filing is needed, and draft professional responses on your behalf. We support CPA firms and individual taxpayers in navigating these decisions confidently.
How to Avoid Future IRS Notices
- Double-check your tax return before filing
- Ensure all income documents are included (W-2, 1099, etc.)
- Report accurate Social Security Numbers and filing status
- Use professional tax software or hire an experienced preparer
- File and pay on time
