Tax Solutions That Stand The Test Of Time

What to do when you receive an IRS notice

On Behalf of | May 19, 2025 | Tax Law

It starts with that envelope — the logo alone might make your stomach drop even before you’ve torn it open, and once you do, it’s easy to spiral.

But before you panic, take a breath and remember: not every IRS notice is a warning shot – some are reminders, others are corrections and a few may simply ask for documents or clarification. The key is knowing how to read what’s in front of you and respond without delay.

What IRS notices are and why you might get one

IRS notices aren’t always about enforcement — some letters, like a CP501 or CP503, simply tell you there’s a balance due, while others, like a CP2000, mean the numbers on your return don’t match what third parties reported. 

You might also get a notice confirming a change to your return or flagging a missing form. Whatever the reason, the IRS usually spells it out — you just need to pay attention to the notice number and the action required, if any.

What to do when a notice lands in your hands

Once you’ve opened the letter and figured out what kind it is, what you do next matters.

You should:

  • Read the notice carefully, not just skim it, but go line by line to understand what the IRS is saying, what they’re asking for and when they expect a response.
  • Compare the notice to your records by reviewing your return, W-2s, 1099s or any other supporting documents to see whether what they’re flagging actually matches what you submitted.
  • Take any deadline seriously by responding on time, whether that means sending documents or making a payment, because waiting too long can lead to penalties, interest or a much bigger issue.
  • Call the number on the notice if you’re still unsure about what it means or how to respond, even if it takes a while to get through, because it’s better to ask now than guess wrong and make things worse later.

A letter from the IRS doesn’t need to throw your entire life off course, but how you handle it will set the tone for what happens next.

When to get help

Some notices are more than just reminders or clerical issues. If the amount is large, the language is vague or intimidating or you’re worried that responding the wrong way could make things worse, it’s smart to get help. That’s not overreacting; it’s protecting yourself. A tax attorney can step in and deal with the IRS directly, especially if there’s more at stake than just a math error.

Don’t let it sit

An IRS notice doesn’t always mean disaster, but ignoring it is almost always the wrong move. If you stay calm, read it closely and respond with purpose, you take control before the situation has a chance to spiral. And if it turns out that you need support, that’s not failure — that’s just a smarter way of getting through it.
