Got a Letter From the IRS?
There's a whole corner of r/tax devoted to one recurring post: "I got a letter from the IRS, am I in trouble?" The answer, almost always, is no. Most IRS letters are routine — a mismatch, a math fix, or a gentle "we need more info." Here's how to handle it without spiraling.

First: Don't Panic (Seriously)
A letter from the IRS is not an audit, and it's not a bill being sent to collections. In the vast majority of cases, it's the IRS doing its job: matching the forms it received against your return and pointing out a discrepancy. You have time, you have options, and the process is far less scary than it looks.
The #1 rule from every experienced poster on r/tax: open the letter, read it slowly, and figure out exactly what it's asking. Do not throw it in a drawer and hope it goes away — that's how a $50 correction turns into penalties. But don't spiral either.
Understand your income picture
Plug in your numbers to see where your tax situation stands.
What a CP2000 Actually Is
The CP2000 is by far the most common notice. It is not a bill — it's a proposal. It says, in plain English: "The income reported to us (from your W-2, 1099, brokerage, etc.) doesn't match what you put on your return. Here's what we think you owe based on that." Common triggers:
- You forgot to report a 1099 (freelance income, interest, dividends).
- A side gig or investment account reported income you didn't include.
- Your reported number just doesn't match the copy the IRS got.
If the IRS is right, you agree and pay the difference. If it's wrong — the 1099 has an error, or the income was already reported elsewhere — you respond with documentation. Either way, it's a fixable paperwork issue, not a crisis.
How to Read the Letter
- Find the notice number (top or bottom corner — CP2000, CP14, etc.).
- Find the deadline — usually "respond by [date]" (typically 30 days).
- Read what changed — the letter lists the specific discrepancy and the proposed tax.
- Check if you agree — compare against your records and the forms you received.
When and How to Respond
- If you agree — follow the letter's instructions to pay the proposed amount (or set up a payment plan if you can't pay in full).
- If you disagree — send a written response before the deadline, with documentation proving your version (corrected 1099, receipts, a statement). Keep copies of everything.
- If it's a real audit (much rarer — actual audits affect a tiny fraction of returns) — the letter will say so explicitly and list what to provide.
Whatever you do, respond by the deadline. Miss it and the proposal becomes a final bill, and your options shrink.
How to Spot an IRS Scam
This is the other half of the r/tax "I got a letter" genre — the people asking "is this real?" Know the rules and you'll never get fooled:
- The IRS never initiates contact by phone, email, or text. Mail first, always.
- The IRS never demands payment via gift cards, wire transfer, or cryptocurrency.
- The IRS never threatens immediate arrest or deportation.
If a "letter" or call does any of those, it's a scam. Hang up, don't click, and don't send anything.
Frequently Asked Questions
Does a CP2000 mean I'm being audited?
No. A CP2000 is an automated matching notice, not an audit. It proposes a change based on forms already on file. A real audit is a separate, much rarer process that will be clearly labeled.
What if I ignore the letter?
Bad idea. The proposed amount can become final, and the IRS can then assess penalties, interest, and eventually take collection action. Always respond by the deadline — even a short "I disagree, details to follow" is better than silence.
How do I know a letter is really from the IRS?
Real IRS notices come in the mail with a notice number, your taxpayer info, and a specific deadline. You can also verify by calling the IRS at its official number (found on irs.gov) — never a number printed on a suspicious letter.
Can I call the IRS to ask about my letter?
Yes. The notice includes a phone number and often a specific department. Hold times can be long, but for confusing situations a phone call can clear things up. Have the letter and your records in front of you.
