The moment you recognize that envelope — the plain one with “Internal Revenue Service” in the corner — your stomach drops. Take a breath. In the vast majority of cases, an IRS letter is far more routine than it feels, and almost every one of them can be sorted out calmly.
Open it — the same day
It’s tempting to set it aside. Don’t. Nearly every IRS notice has a response date, and the clock starts whether you’ve opened it or not. Most letters simply ask you to confirm something, verify your identity, or explain a mismatch. The worst thing you can do is nothing — a problem that’s easy to fix today gets more expensive the longer it sits.
Find the notice number and read what it actually says
Look in the top or bottom right corner for a code starting with CP or LTR. That tells you exactly what kind of letter it is. Usually it’s one of a few things: their records don’t match your return, they need to verify your identity before releasing a refund, they adjusted something, or there’s a balance to pay. A letter proposing a change is not the same as a bill — and neither one is an audit.
Check it against your own records
The IRS is not always right. Their notices are generated automatically by matching forms other people filed about you — W-2s, 1099s, and so on — against your return. Sometimes a form was reported twice, or income that isn’t taxable got flagged. Pull your copy of that year’s return and compare before you assume you owe.
Don’t pay just to make it go away
When a letter shows a number, the instinct is to write a check. But paying an amount you don’t actually owe is money you rarely get back easily. If it’s a proposed change, you have the right to disagree and explain, with documentation, before anything becomes final.
Watch for scams
Real IRS contact about a new issue almost always starts with a letter in the mail — not a phone call, text, or email. Anyone demanding immediate payment by gift card, wire, or crypto is running a scam. When in doubt, slow down and verify.
You don’t have to handle it alone
As an Enrolled Agent, I’m federally authorized to represent taxpayers before the IRS in all 50 states. With your permission, I can call the IRS for you, request your records, respond to the notice, correct their errors, and — if you do owe — set up a payment plan or pursue penalty relief.
