What Should I Do If I Receive an IRS Notice?
Receiving an IRS notice can feel alarming — but most IRS letters are routine. The IRS sends millions of notices each year for a variety of reasons, many of which require only a simple response or no action at all.
First, read the notice carefully to identify the issue. Every IRS notice includes a notice number (such as CP14 or CP2000) and a response deadline. Do not ignore the deadline — failing to respond can escalate the issue.
Common reasons for IRS notices include: a balance due, a refund change, a question about your return, or a verification request. The notice will tell you exactly what the IRS needs from you and how to respond.
Key Takeaways
CP2000 Notice Explained
A CP2000 is not a bill — it is a proposed change notice. The IRS sends CP2000 notices when income reported by third parties (employers, banks, brokers) does not match what was reported on your tax return.
You have the right to agree, partially agree, or disagree with the proposed changes. If you disagree, you must provide documentation supporting your original return. If you agree, you can respond with payment or a payment plan.
Response deadlines are typically 60 days from the notice date. Missing the deadline can result in the IRS automatically adjusting your account.
Key Takeaways
IRS Audit Letter Explained
The IRS may select returns for examination through a letter audit (correspondence audit), office audit, or field audit. Most IRS examinations are correspondence audits conducted entirely by mail.
An audit letter will explain which items on your return are being questioned and what documentation the IRS is requesting. Responding completely and on time is critical.
Not all audits result in additional tax. Many examinations close with no change to the original return when adequate documentation is provided.
Key Takeaways
IRS Balance Due Notice
A balance due notice (such as CP14) means the IRS believes you owe taxes that have not yet been paid. The notice will include the amount owed, interest accrued, and any penalties assessed.
If you agree with the balance, you can pay in full, set up an installment agreement, or explore other resolution options such as an Offer in Compromise.
If you believe the balance is incorrect, you have the right to dispute it by submitting a written explanation and supporting documentation.
Key Takeaways
IRS Identity Verification Letter
The IRS may send identity verification letters (such as Letter 5071C, 6330C, or 4883C) when your tax return is flagged for potential identity theft. The IRS requires you to verify your identity before processing your return.
Most verifications can be completed online through the IRS Identity Verification Service or by calling the number on the letter. You will need to provide your Social Security Number, prior year return information, and supporting identification.
This does not mean your identity has been stolen — it is a preventive measure the IRS uses to protect taxpayers.
Key Takeaways
Understanding IRS Penalty Notices
The IRS assesses penalties for failure to file, failure to pay, and failure to deposit (for payroll). Penalty notices will explain the type of penalty, the period involved, and the amount assessed.
Penalty relief options exist, including First-Time Penalty Abatement and Reasonable Cause relief. These are not automatic — they require a written request and, in some cases, documentation.
Addressing penalties proactively is important because penalties and interest continue to accumulate on unpaid amounts.

Frequently Asked Questions
Do I have to respond to every IRS notice?
Most IRS notices require a response. Some informational notices require no action. Always read the notice fully to understand what is required and by when.
What happens if I miss an IRS notice deadline?
Missing a deadline can result in the IRS automatically adjusting your account, assessing additional penalties, or initiating collection actions. Contact the IRS or a tax professional immediately if you've missed a deadline.
Can I get an extension to respond to an IRS notice?
Extensions are sometimes available and must be requested before the deadline. Contact the IRS directly or work with a tax professional to request additional time.
Is an IRS notice the same as an audit?
No. Most IRS notices are routine communications about specific items on your return. An audit is a formal examination of your return and is a separate process.
