IRS Notices and Alerts: What to Do When You Get One
Updated August 13, 2026.
*Updated Aug. 13, 2026*
You do not need to panic when an IRS notice arrives, but you should not ignore it. Read the notice, identify the CP or LTR number, check the response date, and follow the instructions printed on that document. If you disagree, respond by the listed date and keep copies of everything you send.
The IRS says it may send a notice because you have a balance due, your refund changed, the agency has a question about your return, it needs to verify your identity, it corrected your return, or processing is delayed. The notice should explain the reason for contact and the next step.
This guide explains how to read IRS notices and alerts, verify that a message is real, and respond safely.
Quick answer: Updated August 13, 2026.
What Is an IRS Notice or Letter?
An IRS notice or letter is written communication about your tax account or a tax return. It may ask you to pay, provide information, correct a problem, verify your identity, or review a proposed change.
The number is usually printed near the upper right corner of the first page. It may begin with CP or LTR. That number is the fastest way to find the matching explanation on IRS.gov.
An IRS notice is not automatically a bill, an audit, or proof that you made a mistake. Its meaning depends on the notice number, the tax year, the amounts shown, and the instructions included with it.
Common IRS Notice Types
CP12: The IRS found a math or credit adjustment that may change your refund or balance. Compare the change with your tax return and read whether a response is requested.
CP14: The IRS says you have an unpaid tax balance. Check the amount, tax year, payment deadline, and payment instructions.
CP2000: Information reported by an employer, bank, or another third party does not match your return. Compare the listed income or payment with your records and choose the reply option in the notice.
Identity verification notice: The IRS needs you to confirm your identity before continuing certain work on your account. Use only the official verification instructions and protect your personal information.
Refund or return adjustment notice: The IRS changed information connected to your return or refund. Compare the notice with your filed return and supporting records.
This table is a starting point, not a substitute for reading your complete notice. A single notice number can involve different details depending on the tax year and account information.
How Long Do You Have to Respond to an IRS Notice?
Use the response date printed on your notice. There is no single deadline that applies to every IRS letter.
Some notices ask for a reply by a listed date. Others explain when payment is due or when you can challenge a proposed adjustment. If you disagree and want to protect possible appeal rights, the IRS says to reply by the due date.
A CP2000 notice, for example, explains a proposed change and tells you how to respond. A CP3219A notice can involve a statutory notice of deficiency and a court related deadline. Do not use a general internet estimate when your own notice gives a specific date.
If the deadline is close, gather your records and respond using the method shown on the notice. If you need professional help, contact a qualified tax professional quickly because their review also takes time.
What to Do When You Receive an IRS Notice
1. Keep Every Page
Save the envelope, every page, inserts, response forms, and payment instructions. Scan or copy the notice for your records.
2. Find the Notice Number
Look near the top right of the first page for the CP or LTR number. Search that number on IRS.gov, not through an advertisement or an unfamiliar website.
3. Read the Reason and the Requested Action
Look for four details: the tax year, the reason for the notice, the amount involved, and what the IRS wants you to do.
Some notices require no reply if you agree and no payment is due. Others require a payment, documents, a signed response form, or identity verification.
4. Compare the Notice With Your Records
Review the relevant tax return, W 2 forms, 1099 forms, payment confirmations, receipts, and prior IRS correspondence. Never mail original records unless the notice specifically requires an original document.
5. Respond Through the Listed Method
Your notice may give a mailing address, fax number, secure upload option, phone number, or online instruction. Use the method and address printed on your notice.
6. Keep Proof of Your Response
Save a copy of your response and all attachments. Keep mailing receipts, fax confirmations, upload confirmations, and payment confirmation numbers.
How to Verify an IRS Notice or Alert
The first contact from the IRS is usually by mail. The IRS warns that unexpected messages asking for urgent payment or personal information may be scams.
Use this verification process:
1. Do not click links in an unexpected email or text message. 2. Do not reply with your Social Security number, bank details, tax documents, or account password. 3. Sign in by typing IRS.gov into your browser and opening your secure Online Account. 4. Search the notice number on IRS.gov. 5. Compare the paper notice with the notice or account information shown through the official IRS service. 6. If the letter still looks suspicious, use the IRS contact instructions or call the official IRS number for verification.
The IRS says it does not begin contact through social media or text message. It also warns that scammers may threaten arrest, demand immediate payment, or ask for gift cards and other unusual payment methods.
A polished screenshot can still be false. The safer test is whether the message matches an official IRS source and whether the requested action appears in your secure account or on the notice itself.
What If You Agree With the Notice?
Follow the instructions. If the notice corrects your return and no response or payment is requested, you may not need to contact the IRS. Keep the notice with your tax records.
If the notice says you owe money, pay by the date listed if you can. The IRS provides online payment options and may offer payment plans for people who cannot pay the full balance.
Do not send money to a phone number, email address, or website supplied by a suspicious message. Start at IRS.gov and use the official payment information there.
What If You Disagree With the Notice?
Follow the dispute instructions in the notice and explain the specific item you believe is wrong. Include copies of relevant records, not original documents, unless the IRS specifically requests otherwise.
For a notice about income that does not match your return, compare the third party information with your records. You may need to report corrected information, explain why the item does not belong to you, or provide proof of what you reported.
Respond by the listed deadline. A disagreement does not automatically pause every payment or collection requirement, so read the notice carefully and get professional guidance if the amount or issue is serious.
What If You Cannot Pay the Balance?
Do not ignore a balance simply because you cannot pay it in full. Pay what you can by the due date if possible, then review the official IRS payment options.
The IRS may offer an installment agreement or another collection option depending on your account and eligibility. Interest and penalties may continue, so check the official payment and collection guidance rather than relying on a social media post.
If the notice warns about a levy, lien, or appeal right, treat the date as urgent and review the instructions immediately. You may need help from a tax professional or a Low Income Taxpayer Clinic.
IRS Notice Action Checklist
Use this checklist before you respond:
Save the complete notice and envelope.
Write down the notice number and tax year.
Mark the response or payment date on a calendar.
Compare the notice with your return and supporting records.
Search the notice number on IRS.gov.
Sign in to your official IRS Online Account when appropriate.
Follow the response method printed on the notice.
Send copies, not original records, unless instructed otherwise.
Keep proof of mailing, uploading, faxing, or payment.
Get qualified help when the notice involves identity theft, a large balance, a levy, a court deadline, or a complicated dispute.
Frequently Asked Questions
Do I need to respond to every IRS notice?
No. Some notices only explain a change and do not require a reply when you agree and no payment is due. Read the action section carefully. If the notice requests information, payment, or a response to a disagreement, follow the listed instructions and date.
How do I know if an IRS letter is real?
Find the notice number, search it on IRS.gov, and compare the letter with your secure IRS Online Account when available. Be cautious if a message threatens immediate arrest, demands gift cards, or asks for personal information through email, text, or social media.
Can the IRS contact me by email or text message?
The IRS generally begins contact by mail. An unexpected email or text that claims to be from the IRS should not be trusted automatically. Do not click links or open attachments. Use IRS.gov to verify the issue.
What does CP14 mean?
CP14 generally means the IRS says you have an unpaid tax balance. Check the tax year, amount, payment date, and payment instructions on your own notice. If you disagree, follow the contact instructions in the notice.
What is a CP2000 notice?
A CP2000 notice says information reported by a third party does not match information on your tax return. It explains a proposed change and tells you how to agree, disagree, or provide supporting information. It is not automatically a bill or a formal audit notice.
What happens if I miss the response date?
Contact the IRS using the number or address on the notice and respond as soon as possible. Missing a date can affect appeal rights, collection activity, penalties, interest, or processing. The exact effect depends on the notice type.
Should I call the IRS about a notice?
Follow the notice instructions first. Many questions can be handled by using the notice number, IRS.gov guidance, your Online Account, or the document upload instructions. If you call, keep the notice and your tax records nearby.
Can I get help responding to an IRS notice?
Yes. You can consider a qualified tax professional, the Taxpayer Advocate Service, or a Low Income Taxpayer Clinic when eligible. A notice involving identity theft, a large balance, a levy, a court related deadline, or a complex dispute deserves prompt attention.
