What Is IRS Notice Response?

The IRS and state tax agencies send millions of notices each year — for income discrepancies, missing information, identity verification, balance due, audits, and more. Each notice has a specific purpose, a deadline for response, and potential consequences if ignored. IRS notice response means understanding what the IRS is asking for, preparing a complete and accurate response, and communicating with the agency to resolve the issue.

Most IRS notices are not audits. In fact, the majority are automated computer-generated letters triggered by data mismatches — for example, when income reported on a 1099 doesn't match what you entered on your return. These can often be resolved with a clear explanation and supporting documentation. But even a simple notice can become a serious problem if left unanswered.

At TaxWise LLC, we review your notice, analyze the underlying issue, gather supporting documentation, and prepare a professional response. When needed, we represent you before the IRS or state tax agency via Power of Attorney (Form 2848). Our goal is to resolve the matter as quickly and favorably as possible — and to make sure you understand what happened and why.

Who Needs IRS Notice Response Services?

Individual Taxpayers

You received a CP2000, 12C, 5071C, or other IRS letter and aren't sure what it means or how to respond. A CPA-reviewed response protects your rights and ensures accuracy.

Small Business Owners

Business tax notices can involve employment taxes, sales tax, or income tax discrepancies. A professional response can prevent the issue from disrupting your business.

Cross-Border & Foreign Taxpayers

Notices involving foreign income, foreign tax credits, or international information returns (FBAR, 8938, 3520) require specialized knowledge. A standard response may miss key cross-border issues.

Prior-Year Non-Responders

You received a notice months ago and didn't respond. The IRS has escalated to collection or assessment. It's not too late — but you need experienced help to navigate the options still available.

Audit Notice Recipients

Your return was selected for examination. Whether it's a mail correspondence audit or a field examination, having a CPA represent you from the start typically leads to better outcomes.

Identity Theft Victims

You received a notice about a return you didn't file or income you didn't earn. Identity verification and tax-related identity theft require specific IRS procedures we can guide you through.

Types of IRS & State Notices We Handle

CP2000 — Income Mismatch

The IRS computer found income reported to them (by employers, banks, clients) that doesn't match what you reported on your return. This is the most common IRS notice.

12C Letter — Missing Information

The IRS needs additional information to process your return — typically missing forms, schedules, or clarification of entries on your return.

5071C — Identity Verification

The IRS needs to verify your identity before processing your return. This is an anti-fraud measure. You may need to verify online, by phone, or in person.

Audit Notices (Field, Office, Correspondence)

The IRS has selected your return for examination. Audits range from simple mail correspondence (send us this receipt) to comprehensive field examinations of business records.

Collection Notices (LT11, LT1058, CP504)

The IRS is attempting to collect unpaid tax. These notices may precede enforced collection actions such as wage garnishment, bank levies, or federal tax liens.

State Department of Revenue Notices

Washington DOR and other state tax agencies issue their own notices for income tax, sales tax, B&O tax, and other state-level tax matters.

Why You May Have Received a Notice

You forgot to include a 1099 or W-2 on your return

The IRS received a copy of the form from the payer. Their system cross-checks what you reported against what was reported to them. A mismatch triggers a CP2000.

You had a side gig that paid through a platform

Venmo, PayPal, Etsy, Uber, or similar platforms issue Form 1099-K. If you didn't include that income, the IRS knows about it.

Your tax return was filed without your knowledge

A 5071C letter may indicate someone attempted to file a fraudulent return using your SSN. The IRS wants to confirm it was actually you who filed.

You claimed a credit or deduction the IRS is questioning

The Earned Income Tax Credit (EITC), Child Tax Credit, and certain business deductions have high audit rates. An audit notice asks you to provide proof of eligibility.

You have a balance due from a prior year

Collection notices escalate over time. What starts as a CP14 (balance due) can progress to a CP504 (intent to levy) and then to enforced collection if unaddressed.

There was a math error or processing issue

Sometimes the IRS simply made an adjustment during processing and is notifying you. These are often the easiest to resolve — if you respond promptly.

What to Do When You Receive a Notice

1

Don't panic. Read the notice carefully.

Most IRS notices are not as serious as they look. The notice will tell you what the IRS is proposing, what information they need, and your deadline to respond. Note the notice number (CP2000, 5071C, etc.) and the tax year it references.

2

Gather relevant documents.

Pull together the tax return in question, any supporting documents related to the issue, and all pages of the notice itself. Do not throw away the envelope — it contains the mailing date, which may affect your deadline.

3

Contact us for a review.

Forward us the notice and we will review it — usually at no charge for the initial review — to determine what the IRS is asking for, whether their position appears correct, and what documentation or response is needed. If you'd like us to handle the response, we'll provide a fee estimate.

4

Respond before the deadline.

Missing the response deadline limits your options. In many cases, we can draft and submit the response on your behalf, including a Power of Attorney so we can deal with the IRS directly. Most notices are resolved at this stage without further escalation.

What NOT to Do with an IRS Notice

Avoid These Responses

  • Ignoring the notice — This is the single most damaging response. The IRS will not forget about you. Notices escalate, interest and penalties accrue, and your options narrow the longer you wait.
  • Paying without verifying — IRS notices are wrong a significant percentage of the time. Before paying a proposed assessment, have a CPA review it. If the IRS position is incorrect, paying concedes the issue and makes it harder to recover the funds.
  • Calling the IRS without preparation — Phone wait times can be hours, and without knowing exactly what to say and what to ask, you may not resolve anything. We know which phone numbers to call, what to say, and how to navigate the IRS phone system.
  • Sending original documents — Never mail original documents to the IRS. Send copies. Keep the originals for your records. If the IRS needs to see originals, they will request a meeting.
  • Responding without understanding the issue — A poorly worded response can inadvertently concede points you didn't intend to, or fail to address what the IRS was actually asking for.
  • Assuming a notice is a scam — While IRS scams exist, legitimate IRS notices arrive by U.S. mail (not email, text, or phone call). If you received a physical letter, it is likely real. We can help you verify its authenticity.

Frequently Asked Questions

Should I ignore an IRS notice?
No. Ignoring an IRS notice will not make it go away. The IRS will follow up with additional notices, and the issue can escalate to enforced collections — wage garnishment, bank levies, or tax liens. Most notices have a deadline for response; missing it limits your options. Even if you believe the notice is incorrect, respond promptly with supporting documentation.
What happens if I don't respond?
The consequences depend on the notice type. For a CP2000 (proposed assessment), the IRS will assess the proposed tax. For collection notices, the IRS may proceed with enforced collection. For audit notices, the IRS may make a determination based on the information it has — which may not be in your favor. Generally, the sooner you respond, the more options you have.
How long do I have to respond?
Most IRS notices specify a response deadline — typically 30, 60, or 90 days from the date on the notice. The deadline is stated in the body of the letter. If you are approaching the deadline, contact us immediately. In some cases, we can request additional time before the deadline passes.
Can you talk to the IRS for me?
Yes. As a CPA, we can represent you before the IRS once you sign a Power of Attorney (Form 2848). This authorizes us to communicate with the IRS, access your account information, and respond to notices on your behalf. For most clients, having a CPA handle IRS correspondence reduces stress and ensures a professional response.
What if I actually owe the money?
If the IRS position is correct, we help you evaluate payment options. These may include full payment, an installment agreement, or in certain cases, an Offer in Compromise or penalty abatement. We explain the pros and cons of each and help you choose the best path for your financial situation.
Do you handle state tax notices too?
Yes. We handle notices from state departments of revenue, including Washington DOR and other states. State notices have their own deadlines, rules, and procedures — we respond to them with the same thoroughness as IRS notices.
