The clock is ticking — and for roughly a quarter of American taxpayers, it always seems to come down to the wire. With the April 15, 2026 deadline fast approaching for filing 2025 federal income tax returns, the IRS is bracing for its annual last-minute surge, even as new law changes promise bigger refunds for millions of households.
Here’s where things stand: a new survey by Rasmussen Reports, conducted April 2–3 and 6, 2025, among 1,205 adults, found that 51% of American adults have already filed their returns. Another 28% plan to file by the April 15 deadline, 7% intend to request an extension, and a not-insignificant 14% are still unsure what they’re doing. The margin of error is ±3 percentage points. That last group — the undecideds — is the one tax professionals tend to lose sleep over.
The Last-Minute Rush Is Real — and Risky
IRS data consistently shows that between 20 and 25% of Americans wait until the final two weeks to file. It’s a pattern that repeats every year, and every year it creates the same set of problems: rushed returns, missed deductions, arithmetic errors, and — worst of all — underpayment penalties that start accruing the moment the deadline passes. Think of it as a tax on procrastination.
Missing the deadline without an extension isn’t just stressful. It’s expensive. The IRS currently charges roughly 7% interest on unpaid balances, compounded monthly until the debt is cleared. File late without an extension, and you’re also looking at a failure-to-file penalty on top of that. The math turns ugly fast.
“We know that many hardworking Americans are feeling financial pressure,” said Mark Steber, chief tax officer at Jackson Hewitt Tax Services. “Income taxes aren’t simple, but complexity is the price tag for fairness.” Steber has also flagged that recent law changes — particularly the sweeping provisions of the so-called One Big Beautiful Bill Act — have added new layers of complexity to returns that might otherwise seem routine, urging taxpayers to seek professional help when in doubt.
Bigger Refunds Are Coming — Here’s Why
There is, at least, some genuinely good news buried in all of this. Typical refunds are running approximately 11% higher than the prior year, driven largely by the expanded standard deduction and an enhanced Child Tax Credit under the One Big Beautiful Bill Act. For families who qualify, those changes compound quickly — a higher standard deduction alone reduces taxable income across every bracket, and the CTC expansion puts additional dollars directly back into parents’ pockets.
New breaks for specific groups sweeten the picture further. Tipped workers are seeing federal income tax relief on gratuities, and seniors can now claim an additional $6,000 deduction — changes that, for tens of millions of filers, could meaningfully shift what they owe or what they’ll get back. Exact average refund figures weren’t available in IRS data at press time, but the directional trend is clear.
But it’s not that simple — at least not everywhere. Washington, D.C., has decoupled from several federal provisions, meaning tips and overtime income that are federally exempt may still be fully taxable at the local level. D.C. residents doing the math on their windfall from federal relief may find the local tax bill quietly eating into it. The District did, however, increase its Earned Income Tax Credit match to 100% of the federal EITC — a meaningful offset for lower-income filers, though the dual-calculation burden remains real.
Extensions: A Lifeline, Not a Get-Out-of-Jail Card
So what about that 7% who plan to file for an extension? They’re not wrong to do so — under the right circumstances. Filing Form 4868 by April 15 automatically pushes the return deadline to October 15, and approval is essentially guaranteed. No questions asked, no justification required.
That’s the catch, though. An extension covers the paperwork, not the payment. Any taxes owed are still due on April 15, full stop. Miss that payment deadline and the interest clock starts ticking regardless of the extension. For filers navigating the new complexity of the OBBB — say, a self-employed worker with tip income and a senior dependent — an extension genuinely buys valuable time to get the numbers right. For someone hoping to delay a bill they can’t pay, it offers false comfort.
The steps are straightforward: file Form 4868 before midnight on April 15, estimate what you owe and pay it, then submit the complete return by October 15. Certain groups — Americans living abroad and taxpayers in federally declared disaster areas — receive automatic extensions without needing to file the form at all.
A Warning for Anyone Still Mailing Paper Returns
Here’s something that caught even some tax professionals off guard this cycle: recent changes to USPS operations mean that returns dropped in a mailbox on April 15 may not receive a same-day postmark. Under IRS rules, the postmark date determines whether a return is on time — not the date it arrives. A return mailed April 15 but postmarked April 16 is, technically, a late filing.
The fix is simple but easy to overlook: mail returns one to two days early, or use certified mail with a hand-applied postmark at the post office counter. Better yet, e-file. Electronic filing sidesteps the postmark issue entirely, typically processes faster, and — for most filers — is free through IRS Direct File or authorized software providers. Given everything else that can go wrong near a deadline, this is one risk that’s genuinely not worth taking.
Mark Your Calendar: The Full 2026 Timeline
The April 15 deadline doesn’t exist in a vacuum. The 2026 tax season officially opened in late January, with a structured sequence of dates building toward the peak. January 15 was the due date for the final 2025 estimated tax payment. January 26 marked the official start of filing season. Employers had until February 2 to issue W-2s and 1099s — the documents most individual filers need before they can complete their returns at all.
February 17 was the deadline for updating W-4 exemption claims. March 16 brought due dates for partnerships and S-corporations. And April 15 pulls double duty: it’s both the individual filing deadline and the due date for the first quarterly estimated tax payment for 2026. For Americans living abroad, the deadline extends automatically to June 15, though interest on any unpaid balance still begins accruing from April 15.
The Bottom Line
Most Americans — that 51% who’ve already filed — are done. They’ve moved on. For everyone else, the window is closing, and the combination of new law complexity, mailing rule changes, and the perennial pressure of a hard deadline makes this a year where the usual last-minute scramble carries more risk than usual.
As Steber put it: “Income taxes aren’t simple, but complexity is the price tag for fairness.” Whether that’s reassuring or not probably depends on whether you’ve already filed — or whether you’re still hunting for that missing 1099 somewhere in a kitchen drawer.
