An IRS letter in the mailbox rarely feels good. Some people ignore it and hope it goes away. Some call the number on the page without knowing what they’re agreeing to. Some assume the worst and lose weeks to worry.

None of these tend to end well.

The short answer: Don’t ignore it, and don’t panic. Find the notice number in the top-right corner, find the response deadline, confirm the letter is real, and compare it to your own records before you respond. Most IRS notices are fixable when handled on time.

Here is what your notice means and how to respond without making things harder.

Step 1: Confirm the Letter Is Real

Before you pay or share anything, make sure the IRS actually sent it. The IRS says a letter or notice is the first way it will contact a taxpayer, and it doesn’t make initial contact through email or social media.

You can check a suspicious notice by logging in to your secure IRS Online Account to see if it’s in your file, or by contacting the IRS directly using a number from IRS.gov, not from the letter.

Warning signs of a scam include:

• Demands for immediate payment by gift card, wire or crypto
• Threats of arrest
• Payment instructions that don’t match IRS.gov
• Requests to scan a QR code or send photos of your ID

Real checks are payable to the “United States Treasury.”

Step 2: Identify Your Notice Type

The notice number tells you most of what you need to know. Most IRS notices are not audits. Here is how the common ones differ:

State agencies send notices too. The DC Office of Tax and Revenue, the Maryland Comptroller and Virginia Tax have their own letters and deadlines.

Step 3: Note the Deadline

For a CP2000, you have 30 days from the date on the notice to respond (60 days if you live outside the United States), and the date printed on your notice controls. The IRS describes the CP2000 as not a bill, though your response may be required.

If you do nothing on a CP2000, the IRS can send a CP3219A, the Statutory Notice of Deficiency, and silence can cost you the chance to resolve things through the IRS Office of Appeals. Missing deadlines removes options. 

Step 4: Pull Your Transcripts and Compare

Before you respond, find out what the IRS actually has on file:

1. Download your account and wage and income transcripts from IRS.gov.
2. Compare them to the return you filed and your own records.
3. If a preparer filed your return, request the return and workpapers.

Errors happen. In a CP2000, the mismatch is often a duplicate form, a wrong figure on a third-party document, or income that was already reported on a schedule the IRS’s software missed. Verify the number before you agree to it.

What Not to Do

• Don’t ignore it. Silence narrows your options.
• Don’t call the IRS unprepared. The agent works from your full file. Other years or issues can surface in ways you didn’t expect.
• Don’t accept a payment plan on first contact without looking at your whole situation. Restructuring later is harder than choosing well now.
• Don’t assume the balance is right. Check it against your records.
• Don’t send originals. Send copies and keep proof of delivery.

Step 5: Choose Your Resolution Path

Depending on what the notice raises, one of these may fit:

• Installment agreement: pay over time. Terms depend on the balance, your finances and your compliance history.
• Penalty abatement: penalties can be reduced or removed with reasonable cause or a clean prior record (first-time abatement).
• Currently-not-collectible status: collection pauses when paying would prevent you from covering basic living expenses.
• Offer in compromise: settle for less than the full amount when full payment isn’t realistic. Eligibility is specific, and not everyone qualifies.
• Filing missing returns: if the notice is about years you never filed, the first step is catching up. See what happens when taxes go unfiled or our prior-year filing service.

If the notice is an audit, your first response to the documentation request shapes everything that follows.

When to Bring in a Professional

Handle a simple balance-due notice yourself if the numbers check out and you can pay. Bring in help when:

• The notice involves multiple years or a business
• You disagree with the amount and need to build a response
• You received a CP504, LT11 or CP3219A
• You’re being audited
• You can’t pay in full

Frequently Asked Questions

Does an IRS notice mean I’m being audited?

Usually not. Most notices are balance-due letters, automated corrections or requests for information. Your notice number tells you which. Audit letters, such as Letter 525, say so.

How do I know if an IRS letter is real?

Check the notice number, then look for the same letter in your IRS Online Account. The IRS contacts people by mail first, not by email, text or social media. If anything looks off, contact the IRS through IRS.gov before paying or sharing information.

How long do I have to respond to an IRS notice?

It depends on the notice, but the deadline is printed on the letter. A CP2000 generally allows 30 days. An LT11 requires fast action. Treat the printed date as binding.

What if the amount on my notice is wrong?

You have the right to dispute it. For a CP2000, mark that you disagree on the response form and send supporting documents. Acting before the deadline keeps the most options open.

What happens if I ignore an IRS notice?

The IRS keeps escalating. That can mean added penalties and interest, liens, bank levies and wage garnishment, and you lose options you would otherwise have had.

Can I fix an IRS notice myself?

Often, yes, for simple matters. A professional is worth it when multiple years, a business, an audit or collection action is involved.

Can a tax professional respond to the IRS for me?

Yes. With a power of attorney (Form 2848), an authorized professional can speak to the IRS, review your file and manage the case.

What if I can’t pay what I owe?

Not paying isn’t the same as having no options. Payment plans, penalty relief, hardship status and settlement are all possibilities, and the right one depends on your full financial picture.

Do IRS notices affect my state taxes?

Not automatically, but changes to federal income often lead to state adjustments. If you live or work in DC, Maryland or Virginia, check whether a state notice follows.
