Income mismatch & return changes
The IRS changed something on your return and the change nets to zero — no refund, no balance. A record-keeping notice.
Routine
The IRS changed something on your return and the change nets to zero — no refund, no balance. A record-keeping notice.
Why you got it: A math or data correction washed out — commonly a credit reallocation or an offsetting pair of fixes.
Not a bill and not a refund notice. Its only risk is invisible: the change might matter for a state return or a future year (a corrected credit or carryover).
Your first move: Read what changed, correct your copy of the return, and check whether your state return used the same figures.
The clock on this letter: No response deadline.
Nothing is owed and nothing is due back. If the underlying correction was a math-error adjustment you believe is wrong, the 60-day abatement concept (6213(b)) is the frame — but with a zero balance there is rarely anything to fight about.
And fix your copy so next year's preparer isn't confused.
States often need the same correction.
None required.
A CP13 asking for payment or information upload is fake by definition — the real one asks for nothing.
Nothing happens at the IRS. The only cost of ignoring it is a wrong figure quietly living in your records.

One payment. No subscription. Yours to keep — every notice, every letter, every script.
