While the IRS issues most refunds within 21 days, there is no statutory limit on how long they can take to process a return and issue a refund if it requires further review. Reviews for issues like errors or identity theft can take 45 to 180 days. In cases of identity theft, reviews can exceed 240 days.
The IRS has no maximum time limit when it comes to processing tax refunds, but after 45 days, it is required to pay interest on your refund. In most cases, you can expect the IRS to issue your tax refund within 21 days of filing your tax return.
There is no timeframe for how long the IRS can take to process a tax return before issuing a tax refund.
There's no strict maximum limit for how long the IRS can hold a refund, but they must pay interest after 45 days; while most e-filed returns take 21 days, returns needing extra review for errors, fraud, or certain credits (like EITC/ACTC) can take months (45-180+ days), and amended returns can take 8-16 weeks, with unfiled returns having an indefinite delay until filed.
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.
If the IRS is reviewing your return, it may have questions about your wages and withholding, or credits or expenses shown on your tax return. The review process could take anywhere from 45 to 180 days, depending on the number and types of issues the IRS is reviewing.

Generally, if you fully paid the tax and the IRS denies your tax refund claim, or if the IRS takes no action on the claim within six months, then you may file a refund suit. You can file a suit in a United States District Court or the United States Court of Federal Claims.
The IRS is required to keep the filing open and hold on to unclaimed income tax refunds for three years. If you don't file for the tax refund after three years, the money becomes property of the US Treasury, and you won't be able to get it back.
Things that can delay a refund:
The return has errors, is incomplete or is affected by identity theft or fraud. The return needs a correction to the child tax credit or recovery rebate credit amount.
You must offer a refund to customers if they've told you within 14 days of receiving their item that they want to cancel. They have another 14 days to return the item once they've told you. You must refund the customer within 14 days of receiving the item back.
The IRS can hold your current-year refund if it thinks you made an error on your current-year return, or if the IRS is auditing you or finds a discrepancy on a filed return from the past. If the IRS thinks you made an error on your return, the IRS can change your refund.
However, the IRS is unfortunately not bound by this law. This means that they can choose how much to garnish from your wages each month, depending on how much you owe and how much you earn. The limit is typically between 25-50% of your disposable earnings after deductions are made.
The "20k rule" refers to the traditional IRS threshold for reporting income from payment apps and online marketplaces on Form 1099-K: over $20,000 in gross payments AND more than 200 transactions in a calendar year. While a law (the American Rescue Plan) temporarily lowered the threshold to $600, recent legislation, the One Big Beautiful Bill Act (OBBBA) (OBBBA), has reinstated the $20,000/200-transaction rule for tax years starting in 2025, providing relief for casual sellers and gig workers.
The $75 Rule
According to IRS Publication 463 (Travel, Gift, and Car Expenses), you do not need to keep a receipt for a business expense under $75, except in certain situations. This $75 threshold applies to: Travel-related expenses (such as taxi fares, tolls, or transit passes)
Processing your refund usually takes: Up to 21 days for an e-filed return. 6 weeks or more for returns sent by mail. Longer if your return needs corrections or extra review.
If your tax return is rejected, don't panic. While it could delay your refund, the common reasons for rejection are often easy to fix. If your return was rejected because a return was already filed with your Social Security number, that could mean you were a victim of identity theft.
If your transcript still shows code 570 after six months, the refund may be stuck in review. Call the IRS at 800-829-1040 and ask for a refund-hold review to see what's causing the delay. If it's been over 120 days, you might reach out to the Taxpayer Advocate Service since sometimes they can escalate stalled cases.
Key takeaways. Most people receive refunds within three weeks if they e-file and choose direct deposit; paper returns can take six weeks or more. Filing accurately — especially when claiming credits like the Earned Income Tax Credit— helps prevent refund delays.
Contact the IRS at 800-829-1040 for clarification. If identity verification is required, complete it through the IRS ID.me system as soon as possible. After verification, expect a processing delay of 2-4 weeks before the refund is released.
