What the CP11 Notice Means

A CP11 tells you the IRS made one or more changes to your tax return because it found a miscalculation, and as a result you now owe money. The notice explains exactly what was changed and the new balance. You can agree and pay, or disagree and contact the IRS.

Deadline

Pay by the date on the notice (generally about 21 days) to avoid extra penalties; contact the IRS within 60 days if you disagree.

Why You Received This Notice

A math or calculation error was found on the return. A credit or deduction was adjusted or disallowed. Reported figures did not add up as filed.

What to Do Next

Read the explanation of changes and compare it with your return. If you agree, pay the balance by the due date or set up a payment plan. If you disagree, contact the IRS within 60 days with your explanation and documentation.

What Happens If You Ignore It

If you do nothing, the balance becomes due and penalties and interest accrue, leading to the standard collection notices.
