When it comes to what to do when you, understanding the fundamentals is key. Opening your mailbox to find an envelope from the Internal Revenue Service is enough to make anyone’s stomach drop. But before you let fear take over, take a breath. Not every IRS letter is a crisis. Some are routine, some need quick attention, and some are urgent warnings that require professional help. The key is knowing what you are dealing with and responding the right way.
Understanding What To Do When You in 2026
Every year, the IRS sends millions of notices to taxpayers across the country. These notices cover everything from simple balance reminders to final warnings before enforcement action. Understanding which notice you have received is the first step toward handling it correctly.
Common IRS Notices and What They Mean
CP14: You Owe a Balance
The CP14 is usually the first notice you receive when the IRS says you owe money. It shows the amount of tax, penalties, and interest due. This is not an emergency, but it does require attention. You typically have 21 days to pay or set up a payment arrangement before additional penalties accrue. If the amount seems wrong, you have the right to dispute it.
CP2000: Income Discrepancy
A CP2000 notice means the IRS found a mismatch between what you reported on your tax return and what was reported to them by employers, banks, brokerages, or other third parties. This is not technically an audit, but it functions like one. The IRS is proposing changes to your return and telling you what they think you owe. You have the right to agree, partially agree, or disagree with the proposed changes. Responding within 30 days is critical.
CP501, CP502, CP503, CP504: The Collection Series
These notices escalate in urgency. The CP501 is a reminder that you have an unpaid balance. The CP502 and CP503 are follow-up reminders with increasingly firm language. The CP504 is the one that should get your full attention. It is a Notice of Intent to Levy, which means the IRS is telling you they plan to seize your state tax refund or other assets if you do not respond. Once you receive a CP504, you are running out of time to resolve the matter voluntarily.
CP90 and CP91: Final Notice of Intent to Levy
These are the most serious collection notices the IRS sends. A CP90 is the Final Notice of Intent to Levy and Notice of Your Right to a Hearing. This means the IRS intends to levy your wages, bank accounts, or other assets. You have 30 days from the date of this notice to request a Collection Due Process (CDP) hearing, which temporarily halts enforcement action. The CP91 specifically warns of Social Security benefit levies. If you receive either of these, you need professional help immediately.
How Urgent Is Your Notice?
Not all IRS notices require the same level of urgency. A CP14 balance due notice gives you time to review and respond. A CP2000 income discrepancy requires a thoughtful response within 30 days. But a CP504, CP90, or CP91 means enforcement action is imminent, and delay can cost you real money or access to your assets.
The general rule is this: the higher the number in the CP collection series, the more urgent the situation. And any notice that mentions the word “levy” or “seizure” should be treated as a top priority.
Steps to Take When You Receive an IRS Letter
First, read the entire notice carefully. The IRS always includes the notice number in the upper right corner, the tax year in question, the amount owed or adjustment proposed, and a deadline for response. Do not assume you know what the letter says based on the first paragraph alone.
Second, do not ignore it. This is the single biggest mistake taxpayers make. Ignoring an IRS notice does not make the problem go away. It makes it worse. The IRS will continue to escalate collection efforts, and your options narrow with each step.
Third, gather your records. Pull your tax return for the year in question, along with any supporting documents like W-2s, 1099s, receipts, and bank statements. You may need these to verify your position or respond to proposed changes.
Fourth, respond by the deadline. Every IRS notice includes a response date. Meeting that deadline preserves your rights and keeps your options open. Missing it can result in automatic assessments, loss of appeal rights, or the start of enforcement action.
When to Get Professional Help
While some IRS notices can be handled on your own, many situations benefit from professional representation. Consider getting help if you owe more than you can pay, if the IRS is proposing changes you disagree with, if you have received a CP504 or higher collection notice, if you have unfiled returns for multiple years, or if you simply feel overwhelmed by the process.

An IRS letter is not the end of the world. It is a signal that something needs your attention. The worst thing you can do is ignore it.

Frequently Asked Questions
What should I do if I receive an IRS letter I do not understand?
Start by identifying the notice number in the upper right corner of the letter. You can look up the notice type on IRS.gov or contact a tax professional for help interpreting the letter and determining your best response.
How long do I have to respond to an IRS notice?
Response deadlines vary by notice type. Most give you 30 days from the date printed on the notice. Some balance-due notices allow 21 days. The deadline is always printed on the notice itself, so check it carefully.
Will the IRS garnish my wages without warning?
No. The IRS must send a series of notices before levying your wages. The final warning is typically a CP90 or LT11 notice, which gives you 30 days to respond or request a hearing before the levy takes effect.
Can I negotiate with the IRS on my own?
You can, but it is often not in your best interest. IRS agents are trained negotiators, and the tax code is complex. Professional representation typically results in better outcomes, especially for cases involving significant balances or enforcement actions.
What happens if I ignore an IRS letter?
Ignoring IRS notices leads to escalating collection actions. The IRS will send increasingly urgent letters, eventually resulting in tax liens, bank levies, wage garnishments, or asset seizures. Early response always results in more favorable outcomes.
