What To Do Within 72 Hours of Receiving an IRS Letter

Quick Summary: If you receive an IRS letter, don’t panic. Read it carefully, gather your records, and connect with a qualified tax professional—ideally an Enrolled Agent and Certified Tax Resolution Specialist—to determine your next steps. Acting within 24–72 hours can protect your rights and prevent unnecessary penalties.

Receiving an IRS notice can make anyone uneasy—whether you’re an individual taxpayer or a small business owner. At RHL Accountants in Northbrook, IL, we help clients navigate these moments every day with clarity and confidence. Here’s what you should do right away.

1. Read the Letter Carefully

Not all IRS letters are bad news. Some are simple requests for clarification or documentation. Others involve proposed changes, balances due, or potential enforcement actions. Take a moment to read the notice fully so you understand the reason for the communication and any stated deadlines.

2. Do Not Ignore the Deadline

The IRS typically gives a window—often 30 days—to respond. Missing a deadline can lead to added penalties, interest, or escalated collection activity. Mark the response date on your calendar immediately.

3. Gather Supporting Documents

Collect tax returns, W‑2s, 1099s, business financials, correspondence, or any documents related to the issue. The faster you organize your records, the easier it is for a tax professional to help you respond accurately.

4. Avoid Contacting the IRS Before Speaking With a Professional

Well‑intentioned taxpayers often say the wrong thing when calling the IRS on their own. Before responding, consult an expert who understands IRS procedures and taxpayer rights. As an Enrolled Agent and Certified Tax Resolution Specialist, Robert H. Lewin provides representation that goes far beyond basic tax preparation.

5. Get Professional Guidance Within 24–72 Hours

A quick, informed response can make all the difference. At RHL Accountants, we help individuals and business owners interpret IRS notices, prepare documentation, and communicate with the IRS on their behalf.
