QUICK ANSWER
Find the notice or letter number, read the reason for contact, and note any response or payment deadline. Compare the notice with your tax return and records. Follow its instructions; if you disagree, respond through the stated process with supporting information.
What does the notice say?
The IRS uses notices for many reasons, including a balance due, a refund change, a request for information, or identity verification. Look for the CP or LTR number, usually near the upper-right area, and use the IRS notice lookup to understand it.
Identify the tax year and the exact issue. Do not assume every letter is an audit or that a proposed adjustment is automatically correct.
What should you gather before responding?
- The complete notice, including all pages and enclosures.
- The return for the tax year involved.
- Relevant income statements, receipts, and payment confirmations.
- Earlier correspondence about the same issue.
- A short explanation of any discrepancy you identified.
Keep copies of what you send and a record of when and how you submitted it. Use the contact details and submission method specified for the notice after verifying it is genuine.
What if you agree or disagree?
If you agree, follow the requested action; a separate reply may not be needed unless the notice asks for one. If you disagree, use the notice’s response instructions and include supporting information.
Pay attention to the stated deadline. Missing it can affect available options or appeal rights. If you need help, share the notice promptly with a qualified tax professional rather than waiting until the deadline is close.
How can you check whether the contact is genuine?
Use IRS.gov independently to locate official notice guidance. Treat unexpected links and requests for sensitive information cautiously. If a notice cannot be verified or something seems inconsistent, follow the IRS guidance for checking suspicious correspondence.
Do not send identity documents or tax returns through a public website contact form. Start with a general inquiry and arrange an appropriate way to share sensitive records.
