Step 1: Read It. Actually Read It.

The instinct when an IRS envelope arrives is to set it aside. Don't. The date on that notice starts a clock — and that clock runs whether you've opened the envelope or not.

Read the entire notice. Find the notice number in the upper right corner — it'll say something like "CP14" or "LT11" or "CP2000." That number tells you exactly what the IRS is doing and what they want. Look for the response deadline, which is usually printed prominently on the first page.

Then put it somewhere safe. You will need it.

Step 2: Identify What Kind of Notice It Is

Not all IRS notices are the same. The appropriate response — and the urgency — varies significantly based on the notice type.

Step 3: Don't Call the IRS Yet

This is counterintuitive, but it's important. Calling the IRS the day you receive a notice — without understanding your full situation — is a mistake. The IRS representative on the other end of the line is doing their job, which is to collect. Anything you say about your assets, income, or financial situation becomes part of your file.

Before you call the IRS, you want to know:

The one exception: If you've received an LT11 or CP90 Final Notice of Intent to Levy and you're within the 30-day window, the deadline for protecting your legal rights is more urgent than the risk of an uninformed conversation. In that case, call a professional immediately — not the IRS.

Step 4: Verify the Balance

IRS notices contain errors more often than people realize. Misapplied payments, duplicate assessments, penalties assessed on a year where you had prior compliance, and income reported by a third party that you already reported on your return are all common discrepancies.

You can pull your own IRS account transcript at IRS.gov (under "Get Transcript") to see every assessment, payment, penalty, and notice ever issued on your account. This gives you the full picture — not just what the current notice shows.

If the balance looks wrong, document the discrepancy before you respond. A response that includes evidence of an error is far more effective than one that simply disputes the amount without documentation.

Step 5: Understand Your Options Before You Commit to Anything

The worst outcome of receiving an IRS notice is committing to a resolution path — especially a payment arrangement — before you understand all your options. A payment plan you can't sustain will default. A default restores the full balance and gives the IRS immediate levy authority.

Before agreeing to anything with the IRS:

None of this requires a lawyer. A licensed Enrolled Agent can pull your transcripts, evaluate every option, and tell you what makes sense for your specific situation — usually within a matter of days. That's exactly what our IRS Investigation Retainer covers.

Frequently Asked Questions

What if I can't understand what the IRS notice is asking for?
Every IRS notice has a notice number in the upper right corner — usually a CP or LT designation followed by numbers. That notice number tells you exactly what it is and what the IRS wants. Our IRS Notices hub at defendertax.com/irs-notices covers the 12 most common notices with plain-English explanations of what each one means and what you need to do.
Should I call the IRS directly when I get a notice?
It depends on the notice. For simple math error notices (CP11, CP12), a phone call to verify the correction is fine. For balance-due notices, penalty notices, or anything involving a proposed assessment, you should understand your full situation before speaking with the IRS. Statements you make during an IRS call can be used against you. A professional review before that call is worth the time.
What if the notice says I owe money but I already paid?
Payment processing delays are common. If you paid and received a balance-due notice anyway, gather your payment confirmation, cancelled check, or bank statement showing the transaction. Respond in writing to the IRS with a copy of your payment proof, referencing the notice number. Don't pay twice — verify first.
Is it safe to throw away an IRS notice I don't understand?
Never. IRS notices start deadlines. Even if you don't understand what the notice is asking, the date on it starts a clock — for responding, for appealing, for requesting a hearing. Throwing it away doesn't stop that clock. Put every IRS notice in a folder and find out what it means before you decide what to do with it.
