Should I be worried if my refund is still being processed?

You generally shouldn't worry if your refund is "still being processed," as it means the IRS is working on it, but it might take longer than the typical 21 days due to common issues like errors, incomplete information, or claiming credits like the EITC/ACTC. Worry only becomes necessary if you receive an IRS letter requesting more information or if the "Where's My Refund?" tool shows a specific problem like fraud, but typically, it just means a longer wait, not no refund at all.
