Common IRS refund issues include processing delays due to math errors, incorrect Social Security numbers, or mismatched information. Other common causes include claiming specific credits (EITC, CTC), suspected identity theft, or the refund being offset to pay outstanding debts. Using e-file and direct deposit is recommended to speed up the process.
Your refund may also be delayed if numbers on your return don't match documents the IRS received about your income. Common mistakes can also cause delays, such as math errors or typos on your Social Security number, or if the direct deposit account doesn't match the filing status on your return.
Below, we'll go into more detail about the most common reasons and how each can impact your refund timeline.
If we made any changes to your tax return, your refund amount may change. You'll receive a letter in the mail (Notice of Tax Return Change) with the details of the changes and the updated refund amount. Common changes include: Withholding or payments don't match our records.
Misspelled names. Likewise, a name listed on a tax return should match the name on that person's Social Security card. Entering information inaccurately. Wages, dividends, bank interest, and other income received and that was reported on an information return should be entered carefully.
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.
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.
Taxpayers whose tax returns have been flagged for possible identity theft should receive one of the following letters: Letter 5071C, Potential Identity Theft during Original Processing with Online Option – Provides online and phone options and is issued most widely.
Usually, it takes 4-5 weeks for the refund to be credited to the account of the taxpayer. However, if refund is not received during this duration, the taxpayer must check for intimation regarding discrepancies in ITR; check email for any notification from the IT department regarding the refund.
Businesses that show losses are more likely to be audited, especially if the losses are recurring. The IRS might suspect that you must be making more money than you're reporting. Otherwise, why would you stay in business? Most likely to be audited are taxpayers reporting small business losses.
One-time forgiveness, officially known as First-Time Penalty Abatement (FTA), is an IRS program that allows qualified taxpayers to have certain penalties removed from their tax accounts.
Should your account be selected for audit, we will notify you by mail. We won't initiate an audit by telephone. Assistance is available to help you understand the letter/notice received: Understanding your IRS notice or letter.
If the IRS doesn't think you're eligible to claim the credits based on its return screening filters, it can delay your refund and ask for more information. For example, if the IRS challenges your EITC claim, you'll get Letter CP75, which will ask for proof that you qualify for the EITC.
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.
You may get a letter or notice from the IRS saying there's a problem with your tax return or your refund will be delayed. There are many reasons why the IRS may be holding your refund. You have unfiled or missing tax returns for prior tax years. The check was held or returned due to a problem with the name or address.
The IRS uses a combination of automated and human processes to select which tax returns to audit. Not reporting all of your income is an easy-to-avoid red flag that can lead to an audit. Taking excessive business tax deductions and mixing business and personal expenses can lead to an audit.
The IRS is considering changing an amount on your tax return, due to an examination after it processed your tax return. This is called an audit. If it audits your return, the IRS will notify you by mail, and the notice will tell you if the audit will be handled by mail or in person.
The main 2025 tax refund delay reasons include errors or incomplete information on returns, claims for the Earned Income Tax Credit or Additional Child Tax Credit, identity verification processes, amended returns, and offsets for outstanding debts. Paper returns and bank processing times can also contribute to delays.
Refunds lower because of mathematical errors
Your tax refund may be lower because of a mistake on your tax return. If that happens, the IRS will correct the return. The agency should send you a letter explaining why the amount is different from what you expected.
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.
Your refund is still being processed because of errors, incomplete information, suspected identity theft, complex credits (like EITC/ACTC), or a backlog, requiring extra review beyond the typical 21 days, with status updates available on the IRS Where's My Refund tool. Common causes include math errors, missing signatures, mismatched info, or claiming certain credits that trigger extra scrutiny.
The IRS Where's My Refund tool updates once daily, usually overnight, so checking more often isn't necessary; you'll see status changes as your return moves from "Refund Received" to "Refund Approved" and then "Refund Sent," with most e-filed refunds issued within 21 days, but it can take longer if there are errors or extra review needed.
