CP12, CP21, and refund adjustment notices

RefundHub guide

This thread is for notices that say the IRS changed a return and the refund amount changed.

Quick take
  • Read whether the IRS adjusted a credit, withholding, dependent, filing status, or math item.
  • Compare the notice to your filed return before calling.
  • Deadlines for disagreement can matter.
  • If the notice says no action is needed and you agree, the next step may simply be waiting.

How to use this thread
  • Post the notice number, tax year, what changed, and whether you agree.
