IRS Notice CP05 is a notification sent by the Internal Revenue Service to taxpayers when their filed tax return has been changed after processing. This notice outlines exactly what adjustments were made, why the IRS made them, and how these changes affect the refund or balance due. Receiving CP05 does not mean you are under audit; it simply indicates the IRS found a discrepancy requiring correction.
Background and Purpose
The IRS handles millions of tax returns annually and uses automated systems to verify data such as income reported by employers and financial institutions. When the information you submitted doesn’t match IRS records, or when certain deductions and credits don’t meet IRS criteria, they adjust the return accordingly. Notice CP05 communicates these corrections to ensure taxpayers are fully informed of any amendments.
How Notice CP05 Works
Once your return is filed, the IRS cross-checks details against third-party reports like W-2s or 1099s. If discrepancies arise — for example, if you reported $10,000 income but the IRS has a 1099 showing $15,000 — the IRS recalculates your refund or balance. The CP05 notice will specify:
- The sections of your return that changed
- The originally reported refund or payment amount
- The corrected refund or amount owed
- The reasons behind the modification
This transparency lets you review the IRS’s findings and take action if needed.
Examples of CP05 Adjustments
- Income adjustments: IRS received higher income reports from employers or payers than you declared.
- Deduction or credit disallowances: Claimed deductions or credits don’t meet IRS rules and are reduced or removed.
- Mathematical corrections: Fixing calculation errors on your return.
Who Receives CP05 Notices?
Any taxpayer whose return is adjusted by the IRS may receive CP05. Returns with complex credits or deductions have a higher chance of receiving such notices. The letter is informational, not a penalty or audit notice.
Responding to IRS Notice CP05
- Review the notice carefully: Compare the IRS’s adjustments with your original return.
- Agree with the changes: If you accept the correction, no further action is typically needed.
- Disagree or need clarification: Use the contact information and instructions in the notice to respond, provide documentation, or request further review.
- Do not ignore the notice: Ignoring CP05 can lead to penalties or delays in refund processing.
- Keep records: Store a copy of your notice alongside your tax documents for future reference.
Common Misunderstandings
- CP05 does not mean you are being audited.
- Ignoring the notice can cause financial consequences.
- The IRS’s corrections are often based on reliable third-party data.
