How to respond to an IRS letter

Step 1: Read the whole notice

IRS notices usually explain what the letter is about, what the IRS changed or is asking about, and what it wants from you. The notice number (like CP2000 or CP14) is usually in the top or bottom right corner. Reading every page matters because the response instructions, deadline, and contact information are often on the last page.

Step 2: Find the date and compare it with your records

Every notice has a date printed on it, and most give a deadline to respond, often 30 or 60 days from that date. Check the tax year and the numbers the IRS lists against your own tax return, W-2s, 1099s, or payment records. This comparison tells you whether you agree with the notice or need to push back.

Step 3: Decide if you agree or disagree

1. If you agree with the notice, follow its instructions. For a CP2000, that usually means signing and returning the response form that came with the letter; a letter explaining your agreement is not required.
2. If you disagree, write a short explanation of why, and attach copies, never originals, of the documents that support your position.
3. Send your response using the method the notice describes. Some notices give an online upload option with an access code, some ask for a fax to a specific number, and some ask for mail to a specific address.

Step 4: Send it the way the notice asks

Use the exact method listed on your notice. If the notice offers an online upload tool with an access code, that is usually the fastest option. If it lists a fax number, you can fax your response. If it only gives a mailing address, mail it there.

Sending by Certified Mail with a return receipt gives you proof of when your response was mailed and received, which can be useful if there is a dispute later. The IRS does not require you to send your response this way; it is a choice some people make for their own records.

Step 5: Keep copies of everything

Keep a copy of the notice, your response letter, and every document you sent, along with proof of mailing or the confirmation from an online upload. If the IRS has follow-up questions, or if a later notice refers back to this one, your copies are what you will need.

When to get help

Some notices are straightforward and many people handle them on their own. If the amount involved is large, if you do not understand the notice, or if you are being audited, consider getting help from a CPA, an enrolled agent, or a tax attorney. If you cannot afford representation, the Taxpayer Advocate Service and Low Income Taxpayer Clinics (LITCs) may help for free or at low cost.
