How to Verify IRS Letters and Notices Before You Respond

Getting a letter that appears to come from the tax authority can make anyone’s stomach drop. Some are routine, such as a request for a missing form or a confirmation that a change was made to your return. Others need action by a specific date. And some are not from the tax authority at all. This guide explains how genuine IRS notices normally reach you, how to read them, how to confirm they are real, and how to respond without falling for a scam or missing a deadline.

For the exact, current rules, always rely on irs.gov. Procedures, forms and payment options are updated from time to time, and this article is a general explainer, not tax advice.

How IRS contact usually begins

The usual starting point is a paper letter delivered by post. If the agency needs to question something on your return, correct a figure, ask for documents or tell you that you owe money, the first formal communication is generally a mailed notice.

That has a practical consequence for anyone worried about scams: a phone call, text message or social media message that claims to be a first contact about a debt, with threats of arrest or immediate action, does not match the normal process. Real contact can include later phone calls or visits in particular circumstances, but unexpected pressure by text or voice message as the opening move is a red flag. See the IRS website for its own description of how and when it makes contact.

Also remember what a notice is not. A notice is not a verdict. It is typically a request, a correction or a bill with instructions for how to respond, and you usually have the right to ask questions or disagree.

Reading the notice itself

A genuine letter contains structured information. Take a few minutes to read it fully before doing anything.

• The notice number. Many notices carry a code such as a CP number or a letter number, printed near the top or in a corner. This identifies the type of notice.
• The tax year or period. The letter says which return or period it relates to. Check that it matches a return you actually filed.
• A summary of the issue. It explains what the agency believes is different, missing or owed.
• What you need to do. Look for the specific action requested, such as agreeing, sending documents, or paying.
• The response date. Notices typically state a reply date. Treat that date as important and note it in your calendar.
• Contact details and reference information. Letters usually give a way to ask questions and quote reference details.

If the letter lists a response deadline, follow the date printed on your own letter rather than a figure you read elsewhere. Deadlines differ between notice types, so a general rule you saw online may not apply to you.

Looking up your notice on irs.gov

The IRS publishes explanations of many notice types on its website. A sensible routine is:

1. Write down the notice or letter number exactly as printed.
2. Open a browser and type irs.gov yourself, rather than following a link in the letter, text or email.
3. Use the site search to find the notice number, or browse the section about understanding your notice.
4. Read the description of what the notice means, what the agency expects and what options you have.
5. Compare the web description with your letter. The figures will be yours, but the structure, the type of request and the way to respond should match.

If the number does not seem to exist, or the description is wildly different from what your letter says, pause. It might be a very new notice type, a clerical error or a forgery, and the next step is to verify through official contact channels, not to pay.

How to tell a fake from a real notice

No single sign is conclusive, but several together are persuasive. Compare what you have with this list.

• Unexpected channel. An email or text that says you owe money, or links to a “payment portal”, is unusual for a first contact.
• Threats and extreme urgency. Fake notices often threaten arrest, frozen accounts or a licence being revoked within hours.
• Odd payment instructions. Requests for gift cards, cryptocurrency, wire transfers or payment to a person’s name rather than to the government are warning signs.
• Poor language or formatting. Spelling mistakes, odd phrasing, mismatched logos and generic greetings can suggest a forgery, although well-made fakes exist.
• Links that do not lead to irs.gov. Lookalike addresses may change a letter or add words. Our guide to spotting fake government websites explains how to read an address carefully.
• A return address or phone number you cannot verify. Check the details against those listed on irs.gov, not against the letter itself.
• Requests for sensitive information that the agency would already have. Be careful of any message asking you to send full identification numbers or banking logins by return message.

When in doubt, treat it as unverified until you have checked it through channels you found yourself.

Paying only through official methods

If you do owe money, pay it, but only through routes the agency itself lists.

• Go to irs.gov and look for the payment options page. It describes the ways you can pay and any related steps.
• Never pay with gift cards, prepaid cards or cryptocurrency, and do not hand cash to someone who appears at your door or on a call.
• Do not pay by sending money to an individual or through a payment app unless irs.gov explicitly lists it.
• If you cannot pay the full amount, look at what the site says about payment plans or other arrangements, and consider speaking to a tax professional.
• Keep proof of payment, such as a confirmation number or bank record, with your tax documents.

If you have already paid someone who turned out to be fraudulent, contact your bank or card issuer promptly and read our overview of what to do in related cases in the Social Security scam guide. The steps for freezing credit and reporting identity theft are similar.

Replying and responding sensibly

Even a real notice should be handled in an orderly way.

1. Do not ignore it. Silence rarely makes a problem smaller.
2. Read the whole letter and highlight the action requested and the date by which to respond.
3. Compare it with your records. Check the return, your income documents and any earlier correspondence.
4. Respond in the manner the letter asks. That may be a mailed reply, a response through an online account, or a phone call to the number on the notice if you verified it.
5. Send copies, not originals, of any supporting documents, and keep a copy of everything you send.
6. Use traceable delivery for important mailings, and note the date you sent them.
7. Disagree in writing if you believe the notice is wrong, following the instructions on the letter, and attach evidence.

If you cannot meet the date because of illness or missing documents, check the contact information on the notice and ask what is possible before the date passes. It is better to explain early than to stay silent.

Keeping records that make this easier

Good records turn a stressful letter into a manageable task.

• Keep copies of filed returns and the supporting documents behind them, such as income statements and receipts for deductions you claimed. How long to keep them depends on your situation, so check the guidance on irs.gov.
• Store paper letters in one folder and scan them to a secure digital location as a backup.
• Create a simple log with the notice number, date received, date due, what you did and when.
• Save payment confirmations and any reference numbers.
• Use calendar reminders for dates. Our guides on reminders that work and time blocking in a calendar app show how to turn a deadline into a task you will actually see.

A small amount of tidy organisation also helps if your circumstances change, for example after a move, a new job or a family change that affects your return.

When to bring in a tax professional

Many notices can be handled by the taxpayer alone. Consider outside help if:

• The notice is complicated, or you do not understand what the agency is asking.
• You disagree with the amount and need to present evidence.
• You are unable to pay in full and want to explore options.
• The notice relates to a business, self-employment or foreign income.
• You are being contacted about several tax years at once.
• You are not comfortable dealing with the agency yourself.

Look for a qualified preparer, accountant or other adviser, and check what credentials they hold. Be wary of anyone who promises to eliminate your debt for a fee, asks you to sign a blank form or wants payment into their personal account. Free or low-cost help may be available for people who qualify, and irs.gov describes some of these programs.

Staying alert after a scam attempt

If you receive a fake notice, you can help others by reporting it. The IRS site describes how to report impersonation, and you can also report scams to reportfraud.ftc.gov. If you shared identity details, visit identitytheft.gov for a recovery plan and consider a credit freeze.

A short checklist

• Did it arrive by mail, and does it show a notice number?
• Does the number and description match what irs.gov says?
• Is the response date clear, and have I noted it?
• Are the payment instructions limited to official methods?
• Do my own records agree with the notice?
• Do I need a professional to look at it?

Working through these questions calmly will resolve most notices, and will help you recognise the few that are not what they claim to be.
