An IRS Letter Arrived Before Year-End What Should You Review First?
A notice does not automatically mean you are being audited or that you did something wrong. The IRS writes to taxpayers for many reasons, including account adjustments, payment issues, requests for information, and identity verification. What matters is understanding why the agency contacted you and whether you need to act.
Response deadlines keep running through the holidays, so the sooner you understand your letter, the more options you keep. Here are six things to review first.
1. Identify the notice and the tax period
Not every IRS letter serves the same purpose. Some report a change to your account, others request documents, explain a balance due, or give instructions about a specific tax matter.
Start by finding the notice or letter number, usually printed in the upper-right corner. Notices often begin with “CP” (for example, CP14 or CP2000), while letters are typically labeled “Letter” followed by a number (for example, Letter 1058). Then note these details:
- Notice or letter number: the code that identifies the type of communication.
- Tax year or period: the filing period involved, when stated.
- Response deadline: the date by which you must act, if a response is required.
- Proposed changes or requested information: the adjustments, documents or actions the IRS describes.
These details tell you what the IRS is communicating and which procedures may apply. The specific notice is what matters, not a guess about what it might be.
2. Verify that the letter is legitimate
Tax scams often imitate official correspondence, using IRS terminology, government-style graphics or urgent language to pressure you into sharing personal information or sending money.
If something looks off, check it through official channels. Search for the notice number on IRS.gov, and look in your IRS Online Account, although not every communication appears there. Avoid relying on phone numbers, links or QR codes printed in a suspicious letter. If you need to call, use a number you found yourself on the official IRS website.
Two warning signs are worth remembering. The IRS normally starts contact by mail, and it does not demand payment by gift card or by transfer to a third party. Verifying the source protects both your identity and your money.
3. Review the deadline and the required action
The most important question is whether the IRS expects something from you. Some notices are purely informational. Others ask for documents, explanations or payment within a set period, and certain ones involve rights that must be exercised before a specific date. Missing a required response can limit the options available to you.
A notice proposing changes to your return calls for a different response than one confirming an adjustment that is already complete. Do not assume you can skip a reply just because you agree with the IRS. A CP2000 notice, for example, asks you to return a signed response form even if you accept the proposed changes.
4. Compare the notice with your records
Before agreeing or disagreeing, check what the notice says against your own documents: your filed return, payment confirmations, income forms and other financial records.
The IRS may report that income submitted by a third party does not match your return, or it may have applied a payment differently than you expected. Comparing records helps you tell whether the issue is an error, missing information or a misunderstanding. Judge the notice by the facts and documents of your own situation.
5. Understand what happens if you agree or disagree
What you do next depends on the notice and on whether you believe the information is correct. If you agree, the notice may tell you to make a payment, return a response form or update your records. Some informational notices need no reply at all.
If you disagree, the IRS generally explains how to state your position and submit supporting documents, and you have the right to challenge certain IRS positions. The procedures and deadlines vary by notice, so read the instructions and gather your documentation before you answer. A reply based on assumptions can create new problems.
6. Know when professional representation may help
Some notices are simple. Others involve disputed amounts, proposed assessments, examinations, collection procedures or legal deadlines that are short, and those are the cases where a detailed review pays off. Taxpayers have the right to be represented before the IRS by attorneys, certified public accountants (CPAs) and enrolled agents (EAs).
To authorize a representative, you sign Form 2848, Power of Attorney and Declaration of Representative, which names the representative and the tax matters and periods covered. A power of attorney does not erase your tax obligations. What it provides is professional help reviewing correspondence, preparing responses and meeting procedural requirements.
Why year-end makes an IRS notice more urgent
The calendar adds pressure to an IRS letter in three ways.
- Deadlines do not pause for the holidays. A response date that falls in late December is still a real date, and mail delays or travel can eat into the time you have.
- Documents are harder to gather. Employers, banks and other sources are slower to reply at year-end, so start collecting records as soon as the notice arrives.
- Unpaid balances keep growing. Interest and penalties generally continue to accrue on a balance due, so reviewing your options before the year closes can matter.
Resolving or at least understanding an open notice before January also lets you start the new filing season with a clearer picture of your account.
Common IRS notices and why timing matters
The notices below are among the most common. Deadlines shown are general guidelines; the date printed on your own notice is the one that controls.
Notice | What it generally means | Timing to watch |
CP14 | First notice that you owe a balance | Interest and penalties may keep accruing; the notice lists payment options and a due date |
CP2000 | Income reported by third parties does not match your return | Generally about 30 days to respond, with a signed response form even if you agree |
CP504 | Notice of intent to levy, often state tax refunds and certain other property, after earlier balance-due notices | An escalation step, so contact the IRS or a representative promptly |
Letter 1058 / LT11 | Final Notice of Intent to Levy and Notice of Your Right to a Hearing | Generally 30 days from the date on the letter to request a Collection Due Process hearing |
Notice of deficiency (such as Letter 3219) | Formal notice of a proposed tax assessment | Generally 90 days to petition the U.S. Tax Court, as stated on the notice |
The last two rows carry short legal deadlines that cannot be extended by mail delays, which is why they are the notices where an early professional review matters most.
Understanding the letter is the first step
An IRS notice should not cause panic, but it should not be ignored either. Identify the notice, verify that it is real, check the deadline and compare it with your records. The goal is not to answer fast. It is to answer correctly, based on accurate information and the requirements of your specific notice.
