That just means that the IRS has accepted the return and your refund is now processing it. It's a generic message they provide when they are in processing stage of the return, so there's nothing to be alarmed about.
Once they are done processing it, the status will update on the
Where's My Refund? site for you. Processing time may vary depending on your tax situation. At this stage of processing, there is no further action that you can take right now.
You can contact the IRS to research your status should one of the following three things happen:
- It's been more than 21 days since you received your e-file acceptance notification,
- It's been more than 6 weeks since you mailed your paper return, or
- The Where's My Refund? tool directs you to contact the IRS.
Per the IRS: "By law, the IRS cannot release refunds containing the Earned Income Tax Credit or the Additional Child Tax Credit before mid-February. “Where’s My Refund?” will be updated February 17 for most early filers who claimed the EITC or ACTC. These taxpayers will not see a refund date on “Where's My Refund?” or through their software packages until then. EITC and ACTC refunds should be available in taxpayer bank accounts and debit cards starting Feb. 27, if taxpayers used direct deposit and there are no other issues with their tax returns.”
