Usually, a second tax refund means the IRS or your state has adjusted your return.
Common reasons for a second refund
The IRS or your state may change your refund amount after you file. This often happens for a few specific reasons:
Math corrections: The IRS found and fixed a calculation error on your return. They’ll usually send an IRS CP12 notice in the mail explaining why the amount changed.
State budget surplus: Some states may issue “special surplus refunds” or “rebates” when the state government collects more tax revenue than expected.
Amended return: If you amend your return, a second refund may be sent if the new information changes your situation.
Tax agencies always send a letter to explain any changes they make.
Check your mail: Look for an official notice from the IRS or your state. It'll explain why your refund amount changed.
Use official tools: Visit the IRS Where’s My Refund website. It may provide a status update on adjustments.
Federal vs. state refunds
Federal and state agencies work separately. If you received a refund recently, this second payment might just be the other agency finishing your return.
Check your bank account statement or deposit info. A payment from "IRS TREAS" is federal. A payment from your specific state's Department of Revenue is your state refund.
What you need to do
If the IRS or state has adjusted your return, you typically don't need to file an amendment. However, keep any explanation notice with your tax records. If the notice asks for a response or more information; follow the instructions provided in the letter.
