Sandra, a home health aide in suburban Cleveland, filed her 2025 taxes on February 3rd and expected her $2,340 refund within 21 days. By week seven, her IRS online tracker still read “Return Received” — frozen like a clock that had simply stopped. Then a letter arrived: a CP05 notice asking her to verify her identity before the IRS would release a single dollar. She had no idea what triggered it, and the toll-free number rang busy for days.
Sandra’s situation is not unusual this filing season. Across the country, taxpayers are running into a tangle of processing backlogs, identity verification requirements, and refund adjustments that the IRS has not widely publicized. If you are waiting on a 2025 return right now, understanding what is actually happening — and why — can save you weeks of anxiety and potentially thousands of dollars.
What Is Actually Slowing Down the 2026 Filing Season
The short answer: a combination of staffing changes, new fraud-detection filters, and a surge in complex returns. The IRS processed roughly 160 million individual returns in 2025, and the agency has signaled it expects a similar volume this year. But internal processing capacity has not scaled at the same pace, according to reporting from the Taxpayer Advocate Service.
Three specific factors are creating the most friction right now. First, the IRS expanded its identity theft filters following a spike in fraudulent refund claims. These filters flag returns that share certain characteristics with known fraud patterns — and legitimate filers get caught in the net every day. Second, changes to how the Earned Income Tax Credit (EITC) and Child Tax Credit (CTC) are verified mean that returns claiming those credits face additional scrutiny before release. Third, a growing share of filers submitted amended returns for prior tax years, and those require manual review, consuming agent hours that would otherwise go to current-year processing.
Paper filers face the steepest wait by far. The IRS has consistently warned that mailing a return adds months to the timeline, yet approximately 10 million Americans still file on paper each year. If you are in that group and have not received your refund, the IRS Where’s My Refund tool is the fastest way to check your status — though it will not give you a revised date if your return is under manual review.
Breaking Down the Most Common IRS Delay Notices
Most filers who hit a delay eventually get a letter. The type of notice you receive tells you exactly where your return is stuck and what, if anything, you need to do. Ignoring these letters is the single most expensive mistake a filer can make — some have a response deadline, and missing it can result in a reduced or forfeited refund.
The 5071C notice is the one that catches most people off guard. It requires you to verify your identity online using ID.me or by calling a dedicated IRS line. The verification process can take 20 to 30 minutes, and once completed, the IRS typically releases your refund within 9 weeks. That sounds slow, but filers who ignore the letter and wait have reported waiting five months or more before the IRS rejected their return outright.
How Tax Credits Are Affecting Refund Timing in 2025 Returns
Two credits in particular are causing the most delays this cycle: the Earned Income Tax Credit and the Additional Child Tax Credit. Under the Protecting Americans from Tax Hikes (PATH) Act, the IRS is legally prohibited from issuing refunds that include these credits before mid-February, regardless of when you filed. For the 2026 filing season, that hold date was February 15th — meaning anyone who filed in late January with EITC or ACTC claims had to wait at minimum until late February to see any movement.
Beyond the PATH Act hold, EITC and ACTC claims receive a second layer of review. The IRS cross-references your reported income against W-2 data submitted by employers and 1099s submitted by payers. If there is a discrepancy — even a small one — your return gets flagged for manual verification. This is not a sign you did anything wrong; it is a system that treats mismatches as anomalies worth examining.
For 2025 returns, the maximum EITC is $7,830 for families with three or more qualifying children — a significant sum that the IRS takes seriously from a fraud-prevention standpoint. If your refund is largely made up of EITC or ACTC, build in a realistic expectation of at least six to eight weeks from the date the PATH hold lifted, not from the date you filed.
Steps You Can Take Right Now to Speed Up or Protect Your Refund
There are concrete actions that can either accelerate your refund or prevent it from being reduced without your knowledge. The most powerful tool available to every filer is the IRS online account portal, which shows real-time transcript data — including whether your return has been processed, whether an offset has been applied, and whether any notices have been generated before they arrive in your mailbox.
The Taxpayer Advocate Service is genuinely underutilized. It is an independent organization within the IRS that advocates for taxpayers experiencing significant hardship due to agency delays. TAS case acceptance is not guaranteed, but if a delayed refund is causing documented financial harm, the service can escalate your case in ways a standard IRS phone call cannot.
What Happens Next — and What the 2026 Season Tells Us About Future Filing
The IRS has continued investing in digital infrastructure, and the agency’s Direct File program — which allows eligible filers to submit returns directly through IRS.gov at no cost — expanded its availability for the 2025 tax year. Early data suggests Direct File returns process faster on average than returns submitted through third-party software, likely because formatting errors are eliminated at the source.
The broader implication for taxpayers is this: the era of filing your taxes and passively waiting for a check is effectively over for millions of people. The volume of returns, the sophistication of fraud-detection systems, and the backlog of complex filings mean that active monitoring — checking transcripts, responding to notices promptly, and understanding what each IRS code means — is now part of responsible filing. That is a real shift in what the government expects from ordinary Americans.
As for Sandra in Cleveland: after verifying her identity online and waiting nine more weeks, her full $2,340 refund arrived via direct deposit. She never received an explanation for why she was flagged, which is itself a reflection of how the IRS communicates — or fails to. The system worked, eventually. But for people who depend on that refund to cover rent, prescriptions, or groceries, “eventually” carries a very real cost.
If your return is delayed right now, the most important thing you can do is stay proactive, document every interaction with the IRS, and know your options. The resources exist — the IRS online account, the Taxpayer Advocate Service, and the Where’s My Refund tool — but you have to use them.
