Got an IRS Notice? Here's Exactly What to Do (and Not Do)

That envelope with the IRS logo triggers the same reaction in almost everyone: a stomach drop, then avoidance. Here's the truth — most notices are routine, most are fixable, and the damage almost always comes from what people do after opening it. Or worse, from not opening it at all.

First: open it. Today.

An IRS notice never improves with age. Every notice has a response deadline, and interest and penalties keep running while you avoid it. The single most expensive move a business owner can make is letting notices pile up unopened. We've seen a fixable $800 issue grow into a five-figure problem purely from silence.

What the common notices actually mean

CP14 — "You have a balance due"

The most common notice in the system. The IRS believes you owe money — often from a return filed without full payment. If the amount is right, pay it or set up a payment plan. If it's wrong, respond with documentation. Either way, respond.

CP2000 — "Your return doesn't match our records"

This one isn't a bill — it's a proposal. The IRS matched your return against W-2s, 1099s, and other forms filed under your Social Security number or EIN, and found a difference. Maybe a 1099 you never received. Maybe income that's reported but also has offsetting expenses the IRS can't see. You can agree, partially agree, or dispute it — but the proposed amount often shrinks dramatically once someone who knows what they're doing responds with the full picture.

CP504 — "Notice of intent to levy"

This means earlier notices went unanswered and the IRS is escalating. Take this one seriously — it's a late step before the IRS can start collecting through levies. The good news: even at this stage, payment plans and resolution options are still on the table. The window is just smaller.

Audit and exam letters

Less common than people fear. Most are correspondence audits — the IRS asks for documentation on one or two specific items by mail. Organized records turn these into a paperwork exercise. (More on that in our audit-proofing guide.)

The 5-step response plan

1. Verify it's real. The IRS initiates contact by mail — not by phone call, text, or email demanding gift cards or wire transfers. If someone calls claiming to be the IRS and threatening arrest, it's a scam. A paper notice with a notice number can be verified at IRS.gov.
2. Compare it against your return. Pull the tax year in question. Is the IRS's number right? Sometimes it is — a missed 1099 happens. Sometimes their computer is missing context only your records can provide.
3. Respond before the deadline — in writing, keeping copies. Most notices give you 30 days (some 60, some 90). If you agree, follow the payment instructions. If you disagree, respond with a clear explanation and documentation. Send it certified mail so you have proof.
4. If you owe and can't pay in full, don't panic — and don't ignore. The IRS offers installment agreements, and many can be set up online in minutes. Owing money you can't immediately pay is a solvable problem. Unresponsiveness is what escalates things.
5. Ask about penalty relief. If you have a clean compliance history, first-time penalty abatement can wipe out certain penalties with a single request. Many people qualify and never ask.

The 3 mistakes that make it worse

• Ignoring it. Notices escalate on a schedule. Silence is read as refusal, and refusal leads to enforced collection.
• Paying immediately without checking. IRS notices can be wrong — matching errors, misapplied payments, income counted twice. Verify before you pay, especially on CP2000 proposals.
• Calling the IRS unprepared. Long hold times, and anything you say goes in the file. Know your facts, have your return and records in front of you, and take notes — date, time, agent ID, what was said.

"An IRS notice is a deadline with a stamp on it. Meet the deadline and it's paperwork. Miss it and it's a problem."

Quick questions

Q: Will responding trigger a bigger audit?

No — responding to a notice addresses that notice. Not responding is what invites escalation and additional scrutiny.

Q: The notice is for a year I can barely remember. Now what?

You (or your tax pro) can pull IRS transcripts showing exactly what income was reported under your number for any year. That's usually the fastest way to see what the IRS sees and reconstruct what happened.

Q: When should I get professional help instead of handling it myself?

A simple CP14 for an amount you agree with? You can handle that. A CP2000 proposing thousands in extra tax, anything mentioning levy or lien, multiple years of unfiled returns, or any audit letter — that's when representation pays for itself, often many times over.

P.S. — If you've got a drawer of unopened IRS mail, you're exactly who we help. No judgment, just a plan. We pull your transcripts, figure out where things actually stand, and handle the response. The consultation is free.
