If the IRS says your refund is still processing, it means the agency has your return but hasn’t finished reviewing it. For most e-filed returns that review takes up to 21 days. When it stretches longer, the cause is almost always one of a handful of specific things: an error the IRS is correcting, a fraud or identity check, a legally required hold on certain credits, the slow paper-return queue, or a debt offset that has quietly diverted the money. Which one applies to you decides whether you wait, respond to a letter, or pick up the phone.
Errors and Reviews the IRS Catches Before Paying
The most common reason a return stalls is a mistake caught during the IRS’s initial automated checks. A transposed Social Security number, a missing signature on a paper return, or a math error can pull your return out of automated processing and into a manual queue. Federal law lets the IRS correct math and clerical errors on its own, without going through the formal deficiency process it uses for disputes.1Office of the Law Revision Counsel. 26 USC 6213 – Restrictions Applicable to Deficiencies; Petition to Tax Court In practice that still means a person has to look at your return, compare what you reported against what your employer or bank reported, and either fix the error or send you a letter.
Even a clean return sometimes needs extra time to verify income, withholding, or credits against third-party records. When that happens, you get a CP05 notice explaining a review is underway. The notice asks you to wait up to 60 days before contacting the IRS, and there is nothing to do in the meantime unless a follow-up letter requests documents.2Internal Revenue Service. Understanding Your CP05 Notice Returns flagged for errors or additional review are excluded from the standard 21-day window, so the wait can run well past what you would normally expect.3Internal Revenue Service.

Identity Verification Holds
The IRS runs every return through fraud filters. A large jump in income, a new bank account for direct deposit, or a filing from an unexpected location can trip a hold. You may not know the hold exists until your refund status stops moving or a verification letter arrives.
The most common are Letter 5071C, which offers online and phone verification, and Letter 4883C, which is phone only. International filers may receive Letter 5447C, and in rare cases the IRS sends Letter 5747C, which requires an in-person visit to a Taxpayer Assistance Center.4Taxpayer Advocate Service. Identity Verification and Your Tax Return Online verification through IRS.gov is typically the fastest option.5Internal Revenue Service. Verify Your Return Your refund won’t move until you complete whichever method the letter names, so responding quickly is the single best thing you can do to shorten the delay.
The PATH Act Hold on EITC and Additional Child Tax Credit
Some delays have nothing to do with your return’s accuracy. Under the Protecting Americans from Tax Hikes (PATH) Act, the IRS cannot release any refund that includes the Earned Income Tax Credit or the Additional Child Tax Credit before mid-February. The hold applies to your entire refund, not just the portion tied to those credits.6Internal Revenue Service. When to Expect Your Refund if You Claimed the Earned Income Tax Credit or Additional Child Tax Credit The pause gives the IRS time to cross-check these credits against employer wage reports, which don’t all arrive until late January.
If you claimed either credit and filed early, expect the status to sit unchanged for weeks even though nothing is wrong. The IRS estimates most early EITC and ACTC filers who e-file and choose direct deposit will have their refund by early March, with Where’s My Refund? showing updated status around February 21.6Internal Revenue Service. When to Expect Your Refund if You Claimed the Earned Income Tax Credit or Additional Child Tax Credit Filing earlier won’t get you the money sooner.
Paper Returns and Direct Deposit Snags
How you file has an outsized effect on how long you wait. E-filed returns enter the system almost instantly and generally clear within 21 days. Paper returns have to be opened, sorted, and manually keyed into IRS databases. As of early 2026, the IRS is still working through paper Form 1040s received in February 2026 for original returns and December 2025 for amended returns.3Internal Revenue Service. Processing Status for Tax Forms If you mailed your return, you are essentially in line behind every other envelope that arrived before yours.
Even e-filers hit an occasional snag. The IRS limits electronic deposits to three refunds per bank account per year. A fourth refund directed to the same account, which happens with families filing multiple returns or with amended returns, gets converted to a paper check automatically. That adds about four weeks to the timeline.7Internal Revenue Service. Direct Deposit Limits A notice explains the conversion, but it can be alarming if you weren’t expecting a check.
Refund Offsets: When the Money Was Taken, Not Delayed
Sometimes the refund isn’t stuck. It has been diverted. The Treasury Department’s Bureau of the Fiscal Service runs the Treasury Offset Program, which can apply all or part of your refund to certain debts before you ever see the money. Debts that trigger an offset include:
- Past-due child support
- Federal agency nontax debts, such as defaulted federal student loans
- State income tax obligations
- Certain unemployment compensation debts owed to a state
If your refund is reduced or eliminated because it was applied to a federal tax debt, you’ll receive a CP49 notice.8Internal Revenue Service. Understanding Your CP49 Notice For non-tax debts such as child support or student loans, you can contact the Bureau of the Fiscal Service’s Treasury Offset Program call center at 800-304-3107 to find out whether a debt was submitted.9Internal Revenue Service. Reduced Refund The offset is automatic; if the debt is in the system, the refund gets diverted.
Joint filers can protect their own share of a refund when the debt belongs only to a spouse by filing Form 8379, Injured Spouse Allocation. Processing takes about 11 weeks if filed electronically with your return, 14 weeks if mailed with a paper return, and around 8 weeks if filed on its own after the return has already been processed.10Internal Revenue Service.

How to Check Your Status and When to Call
Two tools show refund status: the Where’s My Refund? page on IRS.gov and the IRS2Go mobile app. Both need your Social Security number or ITIN, filing status, and the exact whole-dollar refund amount from your return.11Internal Revenue Service. About Where’s My Refund? The tracker moves through three stages:
- Return Received: the IRS has your return and is reviewing it.
- Refund Approved: the review is complete and a payment date has been scheduled.
- Refund Sent: the money has gone to your bank or a check has been mailed.
The tool updates once a day, usually overnight, so checking more often shows nothing new.12Internal Revenue Service. How Taxpayers Can Check the Status of Their Federal Tax Refund You can start checking 24 hours after e-filing a current-year return, three to four days after e-filing a prior-year return, or four weeks after mailing a paper return.11Internal Revenue Service. About Where’s My Refund?
Calling too early accomplishes nothing except a long hold. The IRS asks that you wait at least 21 days after e-filing or six weeks after mailing before calling about a refund. For Form 8379, wait 12 weeks for e-filed returns and 14 weeks for paper. If Where’s My Refund? specifically directs you to call, that’s a signal something needs your attention. The main individual line is 800-829-1040, Monday through Friday, 7 a.m. to 7 p.m. local time.13Internal Revenue Service. Let Us Help You Have your return and any notices ready.
If a refund has been delayed more than 30 days beyond what the IRS told you to expect, or the delay is causing financial hardship, you may qualify for help from the Taxpayer Advocate Service. TAS is an independent organization within the IRS that steps in when normal channels haven’t resolved the problem, including when the IRS promised a resolution by a date and missed it.14Internal Revenue Service. Who May Use the Taxpayer Advocate Service TAS can’t override the law. They can’t release a PATH Act refund early, for instance. They can push a return that’s been sitting in a pile for months.
Interest on a Late Refund
If the IRS takes too long, it owes you interest. Federal law gives the IRS 45 days from the filing deadline or the date you actually filed, whichever is later, to issue your refund without paying interest. Past that, interest accrues from the original due date of the return until the check is issued.15Office of the Law Revision Counsel. 26 USC 6611 – Interest on Overpayments For the first quarter of 2026, the individual overpayment rate is 7 percent per year, compounded daily.16Internal Revenue Service. Interest Rates Remain the Same for the First Quarter of 2026 For the second quarter, April through June 2026, the rate dropped to 6 percent.17Internal Revenue Service. Internal Revenue Bulletin: 2026-08 You don’t file a claim for it; the IRS calculates and includes it automatically. The interest is taxable, so you’ll receive a 1099-INT if it exceeds $10.
One catch: if you filed late, after the deadline including extensions, interest doesn’t start accruing until the date you actually filed. Filing late means you lose the benefit of the 45-day clock starting from the original due date.15Office of the Law Revision Counsel. 26 USC 6611 – Interest on Overpayments
