The filing season was formally opened by the IRS on January 26, 2026. Since that date, the agency has begun receiving and processing individual returns. The agency estimates that approximately 164 million declarations This season, most taxpayers are opting for electronic filing.

What’s really different this year? The One, Big, Beautiful Bill Act—OBBBA for short—brings some brand-new tax provisions into play. One of the biggest changes is a new form, Annex 1‑AA, where taxpayers can claim deductions that simply didn’t exist before.
We’re talking about things like exempting certain income from bribes, a break on overtime pay, deductions for vehicle loan interest, and even a separate, higher‑income deduction that works a bit differently depending on where you fall on the earnings scale. All of this can shift what you end up owing—or what you get back as a refund.
Extension Requests: More Time to File, But Not to Pay
Those who are unable to complete their declaration before April 15 have the option of requesting an automatic six-month extension through the Form 4868 This application must be submitted before the original deadline. Once approved, the new deadline for filing the return will be set for October 15, 2026.
However, the extension applies only to the filing of the form. Payment of the amount owed remains due on April 15, regardless of whether an extension was requested. This distinction is important: an extension does not suspend the payment obligation nor does it stop the accrual of interest on outstanding balances.
Failure to pay within the original deadline triggers a mechanism of penalties and interest which accrues costs progressively. The late filing penalty is 5% of the unpaid amount for each month of delay, capped at 25%. In addition, there is a non-payment penalty of 0.5% per month, plus interest calculated at the federal short-term interest rate plus three percentage points. For those who receive a formal notice from the IRS, the non-payment penalty increases to 1% per month.

The U.S. citizens and residents living and working outside the country have an automatic two-month extension, bringing their deadline to June 15, 2026. However, interest on outstanding amounts begins to accrue from April 15, regardless of that extension.
April 15th Also Activates Obligations for Estimated Payments
The same date not only closes the window for 2025 annual tax returns: it also marks the expiration of the first quarterly estimated tax payment for 2026. This obligation falls on taxpayers who do not have sufficient withholding on their income, a category that includes self-employed workers, investors with capital gains, and small business owners.
