What Should You Do If You Receive an IRS Notice in the Mail?

Open it, read it, and respond by the date printed on the letter. That's the short version. Most IRS notices aren't emergencies. They ask a question, flag a mismatch, or request a payment. Ignoring one is what turns a small problem into an expensive one.

Notices can show up weeks or months after you file, and plenty of people stare at the envelope for days before opening it. Don't. If the letter says you owe money, an IRS payment plan can spread the bill out, and if it points to something bigger, you have options for that too.

Start With the Basics Before You Panic

1. Check That the Notice Is Real

Scammers love the IRS name. The IRS typically makes first contact by mail and never uses social media or text messages. A "notice" that shows up as an email, a text, or a direct message is a red flag.

You can confirm a paper letter three ways. Log in to your IRS online account and see if the letter is on file, look the notice up on IRS.gov, or call the IRS directly. Use the phone number printed on the notice or on IRS.gov, never one from a stranger.

2. Find the Notice Number

Real IRS letters carry a specific notice or letter number, usually in the upper right corner. It starts with CP or LT, followed by digits. Search that number on IRS.gov and you'll find a plain explanation of what the letter means. If the number doesn't exist or the content doesn't match, treat the letter as fake.

3. Read What the IRS Is Asking For

Read the whole thing, top to bottom. Slowly. Find three things: why the IRS wrote, what it wants from you, and when it wants it. Underline the date. Write it on your calendar before you do anything else.

Common Notice Types

Some names come up again and again:

• CP2000 means the income on your return doesn't match what employers or banks reported

• CP14 is a first bill for a balance due

• CP504 and LT11 warn that collection action is coming

Each one calls for a different response, which is why the number matters.

How to Respond Without Making It Worse

1. Compare the Notice to Your Return

Pull out your copy of the return for that year and compare it line by line. If the IRS changed something, check whether the change is right. If you agree with the notice, there is generally no need to contact the IRS. If you disagree, you'll need a written response with proof, like a corrected 1099 or a bank statement.

Mistakes cut both ways. Sometimes the IRS is wrong. Sometimes you are. Find out which before you reply.

2. Mind the Deadline

Deadlines vary by notice, but many give you about 30 days. Responding on time protects your appeal rights and limits extra interest. Miss it and the IRS often just sends a bill with penalties added.

If You Need More Time

Call the number on the letter before the deadline passes and ask. Asking early is free. Asking after the date is far less likely to help.

3. Reply the Way the Notice Says

If you mail anything, use the exact address on the notice. A response counts as timely if it's postmarked by the deadline, so send it by certified mail with a return receipt. Keep a full copy of what you sent. Staple nothing you can't replace, and never mail originals.

When the Notice Says You Owe Money

1. Pay It If You Can

Interest keeps running until the balance is gone. If you have the cash, paying in full is the cleanest ending. You can pay through your IRS online account or Direct Pay. Check first that the amount matches your records, since a wrong bill isn't worth paying.

2. Set Up an IRS Payment Plan

Can't pay it all? An IRS payment plan is built for that. A plan generally lowers penalties and stops the IRS from levying your assets while it's in place, though interest still builds. Most people can apply online and learn the answer in minutes. Filing every missing return comes first. The IRS won't approve a plan with returns still outstanding.

Short-Term and Long-Term Plans

A short-term plan gives you an extra 180 days if your balance is under $100,000. A long-term plan, also called an installment agreement, is for balances under $50,000, and balances from $25,000 to $50,000 must use direct debit. Monthly payments can run up to six years. Short-term plans carry no setup fee. Long-term ones do, and the fee is lower with direct debit.

My advice: pick a monthly payment you can still afford in a bad month. A defaulted plan is worse than a slightly longer one.

3. Ask About Penalty Relief

Penalties can sometimes be reduced or removed. First-time abatement may apply if your record was clean for the prior three years. Reasonable cause, such as a serious illness or a disaster, can also qualify. You have to request it, and you need documents to back it up.

Serious Notices That Need Fast Action

1. Notices of Intent to Levy

The Final Notice of Intent to Levy, labeled LT11 or Letter 1058, warns that collection actions may begin. This one has a hard clock. You generally get 30 days to request a collection due process hearing, and that right is lost if you wait. If you see either name on your letter, stop reading blogs and get help that day.

2. Audits and Proposed Changes

An audit letter feels worse than it often is. Many are handled entirely by mail and ask for proof of a few items. Gather the documents requested, send only what's asked, and keep your answers short and factual. Don't volunteer extra. Don't ignore it. A proposed change you ignore becomes a bill you owe.

3. When Tax Resolution Makes Sense

Tax resolution is the work of settling a tax problem with the IRS: negotiating payment plans, requesting penalty relief, responding to audits, and stopping collection. You don't need it for every letter. You need it when the debt is large, when several years are missing, when levy notices are arriving, or when you aren't sure what you owe. Enrolled agents are federally licensed to represent taxpayers before the IRS, and can review a notice, speak with the IRS for you, and work toward a resolution.

Keeping Records and Avoiding the Next One

1. Keep Everything

Save the original notice, the envelope if the postmark matters, and every page you send back. Put it all in one folder labeled with the tax year. Months later, when the IRS writes again, you'll be glad the paper is in one place.

2. Give Your Preparer Authority to Speak for You

You can sign Form 2848, which lets a representative such as an enrolled agent talk to the IRS on your behalf. It means you don't have to sit on hold or decode the response yourself. The IRS sends copies of notices to your representative, too.

3. Stay Ahead Next Year

Most notices come from simple mismatches. Collect every W-2 and 1099 before filing, report all income, and keep your address current with the IRS. If you owe, pay what you can by April 15, since an extension covers filing only. California's FTB sends its own notices, and the same rules apply: read it, check it, respond on time.

Conclusion

An IRS letter is a question, not a verdict. Verify it, read it, mark the deadline, and answer in the way it asks. If you owe, compare paying in full against an IRS payment plan. If the notice is a levy warning or the debt is large, tax resolution help is worth the call. TT Tax and Business Services is open Monday to Friday, 9am to 5pm, at (714) 462-8098, and you can bring the letter in exactly as it arrived.
