Got a Letter From the IRS? What It Means and What to Do
Received an IRS notice like a CP2000, CP14 or CP504? What common IRS letters mean, the deadlines that matter, and how an Enrolled Agent can help.
10/21/20265 min read
Few things in the mailbox cause more stress than an envelope from the Internal Revenue Service. But most IRS letters aren't emergencies. Many are simple requests for information, notices about a small change, or reminders about a balance.
What matters is that you don't ignore it. Nearly every IRS notice has a deadline, and your options shrink each time one passes.
Here's what the most common IRS letters mean, what to do when you receive one, and when it's time to get professional help.
Step 1: Make Sure the Letter Is Real
Scammers love to pretend to be the IRS. Before you act, check these points:
The IRS starts contact by mail. It does not start contact by email, text message or social media, and it won't call demanding immediate payment.
The IRS never asks for payment by gift card, wire transfer to a third party, or cryptocurrency.
Real notices have a notice or letter number (such as CP14 or CP2000), usually in the top or bottom right corner. You can look it up on IRS.gov.
You can confirm balances and notices by logging in to your IRS Online Account on IRS.gov. Never use a phone number or link from a suspicious message.
Step 2: Identify What Kind of Notice It Is
Here are the IRS notices we see most often at our Palm Harbor office:
CP14: Balance Due
You owe tax, penalties or interest on a filed return. This is usually the first bill. Pay it, set up a payment plan, or respond if you believe it's wrong.
CP501 and CP503: Reminders
Follow-up reminders that a balance is still unpaid. Interest and penalties keep growing.
CP504: Notice of Intent to Levy
A more serious notice. The IRS warns that it may seize (levy) certain property or rights, including state tax refunds. Act quickly.
LT11 or Letter 1058: Final Notice of Intent to Levy
This is the big one. You generally have 30 days to request a Collection Due Process hearing, which protects important appeal rights. Don't miss this deadline.
CP2000: Underreported Income
The IRS compared your return to the W-2s, 1099s and other forms it received and found income that doesn't match. A CP2000 is a proposal, not a bill. You can agree, partially agree, or disagree with documentation. Respond by the date on the notice (usually about 30 days).
This notice has become more common as more side-gig and online income is reported on Forms 1099-NEC and 1099-K.
CP12: Math Error Correction
The IRS corrected a calculation on your return, which changed your refund or balance. If you disagree, you generally have 60 days to contact the IRS.
Letter 5071C: Identity Verification
The IRS needs to confirm you filed the return before processing it. Follow the instructions in the letter. Until you do, your refund will be held.
Letter 566 or 525: Audit (Examination)
Most audits are correspondence audits done entirely by mail. The IRS asks you to support specific items, such as deductions or business expenses. Organized records make a huge difference.
CP3219A: Notice of Deficiency
Sometimes called a "90-day letter." You have 90 days to petition the U.S. Tax Court if you disagree. After that, the IRS can assess the tax.
Step 3: Read It Carefully and Note the Deadline
Every notice tells you:
Which tax year and form it's about
What the IRS changed or is asking for
How much (if anything) it says you owe
The date you must respond by
Write the deadline on your calendar right away. Then compare the notice to your copy of the tax return.
Step 4: Respond the Right Way
If you agree: follow the instructions and pay, or set up a payment plan if you can't pay in full.
If you disagree: send a written response with copies (never originals) of supporting documents before the deadline.
Keep copies of everything you send, and use certified mail or the IRS upload tool if the notice offers one.
Don't ignore it, even if you can't pay. The IRS has payment plans, and penalties grow faster when you stay silent.
What If You Can't Pay?
You have options:
Short-term payment plan (up to 180 days)
Long-term installment agreement (monthly payments)
Penalty relief, including first-time penalty abatement if you have a clean history, or reasonable cause relief for situations like illness or disasters
Currently Not Collectible status or an Offer in Compromise in cases of real financial hardship
The right option depends on your income, assets and history, and the paperwork matters.
When to Get Professional Help
You can handle a simple notice yourself. Consider getting help if:
The notice involves a levy, lien or final notice
You've received a CP2000 or audit letter involving business income or large amounts
You have unfiled returns from previous years
You owe more than you can pay
You simply don't want to talk to the IRS yourself
An Enrolled Agent is a federally licensed tax professional with unlimited rights to represent taxpayers before the IRS. With your signed authorization (Form 2848), we can speak to the IRS for you, get your account transcripts, respond to notices, and negotiate payment plans or penalty relief.
Don't Forget Florida Notices
Florida has no personal income tax, but businesses can still receive notices from the Florida Department of Revenue about sales tax, reemployment tax or corporate income tax. The same rule applies: read it, note the deadline, and respond on time. See our Florida sales tax guide.

Frequently Asked Questions
Does a letter from the IRS mean I'm being audited?
Usually not. Most IRS letters are about balances, small corrections or requests for information. Audit letters clearly state that your return is being examined.
How long do I have to respond to an IRS letter?
It depends on the notice. Many give 30 days, some 60 or 90. The exact date is printed on your letter.
Can someone talk to the IRS for me?
Yes. An Enrolled Agent, CPA or attorney can represent you with a signed Form 2848 (Power of Attorney).
What happens if I ignore an IRS notice?
Penalties and interest keep growing, and the IRS can eventually file a tax lien or levy your bank account, wages or refunds.
