IRS CP13 Notice: What It Means and How to Respond

Receiving an IRS letter can cause stress, but understanding it can make all the difference. The IRS CP13 Notice means the IRS reviewed your return and made a change that results in you owing more tax. Let's break down what this notice means and what you should do next.

What Is an IRS CP13 Notice?

The CP13 is sent when the IRS:

  • Found a mistake or discrepancy in your tax return calculations
  • Corrected your return on their end
  • Determined you owe additional tax because of their correction

This notice will show:

  • The original amount you reported
  • The IRS's adjusted tax amount
  • The new balance due
  • The deadline to pay or respond
Why Would I Get a CP13 Notice?

Common reasons include:

  • Misreporting income or deductions
  • Incorrectly calculating credits
  • Mathematical errors
  • Missing or misreported information from third parties (employers, banks, etc.)
What Should I Do After Receiving CP13?

Step 1: Review the Changes
Compare the IRS's calculations with your original tax return.

Step 2: Decide If You Agree or Disagree

  • If you agree, pay the amount due by the deadline to avoid penalties and interest.
  • If you disagree, gather your documentation and contact the IRS immediately to dispute the change.

Step 3: Respond Quickly
You usually have 60 days from the notice date to appeal or pay.

What If I Ignore a CP13 Notice?

Ignoring it can lead to:

  • Increased interest and penalties
  • Potential IRS collection actions
