Internal Revenue Service Races the Clock as April 15 Deadline Hits in Four Days
The Internal Revenue Service is now in its final sprint of the 2026 tax filing season, with millions of Americans still scrambling to submit their returns before the Wednesday, April 15 deadline — four days from today. The agency is pulling out every available resource to help last-minute filers get across the finish line, from expanded in-person hours to digital tools, while warning that the clock is no longer a friend to procrastinators.
The Internal Revenue Service issued a fresh reminder on April 9 that the April 15 tax deadline is next week, urging those who have not yet filed to act immediately. The pressure is real. As of late March, the IRS had already processed more than 78 million individual federal income tax returns and issued 57 million refunds via direct deposit, with the average refund running more than 10 percent higher than last year and total refunds topping $202 billion.
To accommodate last-minute filers, the Internal Revenue Service is opening select Taxpayer Assistance Centers on Saturday with extended hours, including its Tampa office from 9 a.m. to 4 p.m. at 3848 W. Columbus Drive, with no appointment required. This is part of a broader push the agency launched weeks ago. The IRS had previously extended weekly office hours at more than 200 Taxpayer Assistance Centers nationwide, offering taxpayers additional time to receive in-person help during this filing season.
A significant wrinkle this year involves the U.S. Postal Service. USPS changed its transportation operations in January, meaning some mail may no longer arrive at processing facilities on the same day it is collected — a shift that could cause a mailed tax return to receive a later postmark than the day a taxpayer actually dropped it off. Tax experts are urging anyone still planning to mail a paper return to either head to a post office counter and request a manual postmark, or simply abandon paper altogether and file electronically.
New Schedule 1-A is one of the most important forms this year, allowing taxpayers to claim recently enacted deductions under the One, Big, Beautiful Bill, including no tax on tips, no tax on overtime, no tax on car loan interest, and an enhanced deduction for seniors. These provisions have reshaped what many filers owe or are due to receive. Tax professionals report that the average filer is seeing roughly a 10 percent increase in refunds, or an equivalent reduction in what they owe, tied directly to those new incentives — savings that vanish immediately if a return is filed late.
The Internal Revenue Service also just announced a major expansion of its Business Tax Account, making the online self-service platform available to partnerships, governments, Indian tribal governments, and tax-exempt organizations — a structural change that extends the agency's digital footprint well beyond individual filers this season.
Taxpayers who cannot file by April 15 can still request an automatic extension, but the extension applies only to filing, not to payment — any taxes owed must still be paid by the April 15 deadline to avoid penalties and interest. The failure-to-file penalty runs at 5 percent of unpaid taxes for each month a return is late, up to a maximum of 25 percent of the unpaid balance.
The Internal Revenue Service also confirmed that over 1.3 million people across the nation have unclaimed refunds for tax year 2022 and face the same April 15 deadline to collect them — money that disappears permanently once the three-year statute of limitations expires. For those individuals, filing is not just a legal obligation; it is a financial recovery mission.
IRS.gov remains available 24 hours a day with filing tools, refund tracking, payment options, and answers to questions about new tax law changes. With four days left, the Internal Revenue Service message is uniform and direct: file now, pay what you can, and do not wait for Wednesday.
