Received an IRS Notice? Here’s Your Game Plan.

Getting mail from the IRS can be stressful, but there is no need to panic. Most notices are simply requests for more information or corrections of small math errors.

Follow these four steps to handle it like a pro:

Table of Contents

1. Authenticate the Letter

Before you react, make sure it’s real.

The IRS communicates via USPS. If you received an email, text, or DM, it is a scam.
Locate the ID. Look at the top or bottom right corner for a code starting with CP or LTR.
Verify on IRS.gov. Search the specific code on the official IRS website to confirm its purpose.

2. Decode the Request

The letter will usually fall into one of three categories:

The “Correction”: They found a math error and adjusted your refund or balance.
The “Inquiry”: They need to verify your identity or ask for a missing document (like a 1099).
The “Demand”: They believe you owe back taxes or penalties.

3. Respond—Don’t Ignore

Deadlines matter. Most notices give you 30 days to respond before interest or penalties escalate.

If you agree: Follow the instructions to sign and pay (if applicable). You can often set up payment plans online.
If you disagree: Do not file an amended return yet. Instead, mail a letter explaining the discrepancy along with photocopies (never originals) of your supporting documents.

4. Use Modern Tools

In 2026, you don’t always have to rely on the “snail mail” wait times.

IRS Document Upload Tool: Check your notice for a unique access code. This allows you to upload your response digitally for faster processing.
Online Account: Log into your IRS Online Account to view your balance and payment history in real-time.

Quick Guide: Common 2026 Notices

Code	Meaning	Priority
CP2000	Income Mismatch (Missing W2/1099)	High – Compare with your records immediately.
CP14	You have a balance due	High – Pay or start a payment plan.
CP12	They fixed a math error	Low – Just check their math against yours.

A Note on Audits: Receiving a notice does not mean you are being audited. Most of these are “Correspondence Exams” that are resolved with a single letter or upload.
