Requested Changes: Refund
The IRS made the changes you requested for a tax year, and those changes result in a refund.
Read the official IRS pageWhat a standard notice signals
Standard notices are the IRS opening a conversation: a balance reminder, a request for information, or a change it has made to a return. Receiving one does not mean you have done anything wrong, and there is normally time to respond before anything escalates.
What to do next
- Read the notice in full and find the response date printed on it. That date, not anything on this page, governs your case.
- Check the figures against your own records. Notices are sometimes issued on incomplete or mismatched information.
- Do not ignore it. Almost every escalation in the IRS collection sequence begins with an earlier notice that went unanswered.
- If the amount is disputed, you cannot pay it, or you are unsure what is being asked, speak with a licensed professional before the date on the notice passes.
