There are few things that create immediate anxiety quite like pulling an envelope out of your mailbox and seeing those words: Department of the Treasury, Internal Revenue Service. Most people freeze. Some ignore it. Others panic and make decisions they later regret.
Here is the most important thing to understand before anything else: an IRS notice is not a crisis. It is a communication. And like any communication, the right response starts with actually reading it — calmly, carefully, and without jumping to conclusions.
What you do in the first few days after receiving a notice matters more than most people realize. Here is exactly what to do.
This sounds obvious, but it is the most common mistake people make. The IRS sends notices with response deadlines. If you miss those deadlines — or simply do not respond — your options narrow significantly. A problem that could have been resolved with a simple response becomes a much more complicated situation when the IRS takes further action due to non-response.
Whatever you do, do not put it in a drawer and hope it goes away. It will not. Ignoring IRS correspondence is almost always the worst possible choice.
The IRS does not go away when ignored. They escalate. Every deadline you miss reduces your options and increases your exposure. The single most important step is the first one: open the letter and read it.
Step 2: Read It Carefully — and Understand What It Actually Says
IRS notices are intimidating by design, but they are structured documents. Every notice has a notice number in the upper right corner — usually starting with CP or LT. That number tells you exactly what the IRS is communicating and why.
Some of the most common notices include:
The IRS believes your reported income does not match information they received from third parties. This is not an audit — it is a proposed adjustment.
Balance due notices, escalating in urgency. CP504 is the most serious and indicates the IRS may levy your assets.
Final notice of intent to levy. This requires immediate action.
The IRS is questioning income, payments, or credits on your return and wants you to respond.
A Statutory Notice of Deficiency. You have 90 days to respond before the IRS assessment becomes final.
The notice will tell you what the IRS believes, what they are proposing, and what they need from you. Read every word. Note the deadline prominently.
Step 3: Do Not Call the IRS First
This may be counterintuitive, but calling the IRS before you fully understand your situation — and ideally before you have professional representation — can create more problems than it solves. IRS agents are doing their job, and anything you say can be used to further the case against you. If you call without understanding what you are dealing with, you may inadvertently confirm information or waive rights you did not know you had.
There is a time to contact the IRS. That time is after you understand what the notice says, have gathered the relevant documentation, and ideally have a CPA who can communicate on your behalf.
Step 4: Gather Your Documentation
Most IRS notices are triggered by a discrepancy — income reported on a W-2 or 1099 that does not match what appeared on your return, a deduction the IRS is questioning, or a payment they do not have a record of receiving. Pull the relevant tax return, the supporting documents, and any records that relate to what the IRS is questioning.
If the notice involves a specific line item on your return, find the documentation that supports that position. If it involves a payment you made, find the proof of payment. Organization at this stage makes every subsequent step faster and more effective.
Step 5: Contact a CPA or Tax Professional
If the notice is anything more than a simple informational letter or a minor correction, contact a CPA before you respond. A qualified tax professional can:
✦
Interpret the notice accurately and tell you exactly what the IRS is claiming
✦
Assess whether the IRS position is correct or disputable
✦
Prepare a response that protects your rights and addresses the issue properly
✦
Communicate directly with the IRS on your behalf
✦
Negotiate payment arrangements, penalty abatements, or settlements where applicable
Not every CPA has experience with IRS representation. Make sure the person you are working with has handled notices and representation before — this is not the time for on-the-job learning.
Step 6: Respond by the Deadline
Every IRS notice has a response deadline. Some give you 30 days. Others give you 60. A Statutory Notice of Deficiency gives you 90 days to file a petition with the Tax Court — after which the assessment becomes final and the IRS can begin collection action.
Missing a response deadline does not mean your case is over, but it does mean your options have changed — usually for the worse. Respond on time, even if your response is simply to request an extension or to indicate that you are working with a professional.
What Happens If You Cannot Pay?
If the notice involves a balance you genuinely cannot pay in full, do not let that stop you from responding. The IRS has several programs designed for exactly this situation — installment agreements, currently not collectible status, and in some cases an Offer in Compromise, which allows you to settle your debt for less than the full amount owed.
The worst thing you can do is avoid the situation because you cannot afford to pay everything at once. The IRS would almost always rather work out a payment arrangement than pursue aggressive collection action — but you have to engage with them to access those options.
An IRS notice is a communication, not a verdict. Most notices are resolved without any penalty, simply by responding with the right documentation or a well-constructed explanation. The ones that escalate into serious problems almost always do so because of inaction — not because the underlying issue was unsolvable.
Read it. Understand it. Get help if you need it. Respond on time. That is the framework that turns most IRS notices from a crisis into a manageable situation.
