You should generally worry about your tax refund if it has been more than 21 days since you electronically filed or more than 6 weeks since you mailed a paper return. While the IRS processes most refunds quickly, delays often occur due to errors (incorrect Social Security numbers, missing forms), identity theft, or claims for the Earned Income Tax Credit (EITC) or Additional Child Tax Credit (ACTC).

Should I be worried if my tax 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. 

How will I know if something is wrong with my tax return?

Why are IRS refunds taking so long?

A tax refund could be delayed weeks or even months in some cases. The length of the delay may depend on how backed up the IRS is on processing tax returns, whether you turn around requested documentation quickly, and whether you need to file an amended return.

What's the longest the IRS can take to refund?

The IRS doesn't have a strict maximum time limit for issuing refunds, but generally processes e-filed returns with direct deposit within 21 days, while paper returns take 6 weeks or more, with longer waits for those claiming certain credits (EITC/ACTC) or if errors occur. If the IRS holds your refund for more than 45 days past the tax deadline (or filing date if late), they owe you interest, but significant delays (months) can happen for complex issues or extra reviews, sometimes requiring a mailed notice.
