IRS refund delays are commonly caused by errors on returns, incomplete information, claiming specific tax credits (EITC or ACTC), or suspected identity theft. Filing paper returns, having data mismatches (like SSN errors), or owing outstanding debts (child support, student loans) can also trigger significant processing holds.

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

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. 

Why is my tax refund taking so long to be approved in 2025?

Why are income tax refunds delayed?

Income tax refund delays often stem from errors or incomplete information (like incorrect SSNs or bank details), identity theft/fraud checks, claims for certain credits (EITC, ACTC), or needing to verify income matching IRS records, with paper returns and past-due filings also slowing things down. The IRS needs extra time to resolve discrepancies, conduct reviews, or process complex forms like Form 8379, extending the usual 21-day electronic refund period. 

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.
