An unexpected letter from the IRS can be unsettling, but it doesn’t always signal a major issue. Millions of notices are sent each year for reasons as minor as a math error or a missing form. The most important thing you can do is respond calmly, clearly, and on time.
Common Reasons for IRS Notices
The IRS may send a notice for several reasons, including:
A mismatch between your return and IRS records
Missing or incorrect documents like 1099s, W-2s, or K-1s
A balance due or overpayment
Questions about deductions or tax credits
An audit notification or request for documentation
Each notice includes a letter code (e.g., CP2000, LT11) that identifies the issue and what the IRS is asking for.
First Steps: Stay Calm and Get Organized
Start by reviewing the notice carefully. Check the tax year, the details of the issue, and the required response deadline, which is usually within 30 days of the notice date.
Key Actions to Take
Do not ignore the notice: Failing to respond can lead to penalties or enforcement action.
Compare with your records: Review tax filings, income documents, and deductions for the relevant year.
Assess the IRS's claim: Some notices involve straightforward corrections, while others need deeper investigation.
If You Agree with the IRS Notice
Sometimes the IRS is right—a document may have been missed, or a correction is warranted.
Next Steps If You Agree
Follow the notice instructions to submit payment or missing forms
Use the IRS payment portal or mail a check with the voucher provided
Keep copies of everything you send, including dates and confirmation
Resolving it promptly can prevent added interest or penalties.
If You Disagree with the IRS Notice
You don’t have to accept a notice at face value. If the information is inaccurate, you have the right to respond.
How to Dispute a Notice
Gather relevant documents (e.g., W-2s, 1099s, receipts, account records)
Draft a clear explanation of the discrepancy
Submit your response and supporting documents by the listed deadline
Send via certified mail or use the IRS portal to ensure delivery tracking
