when is tax return due
For the current U.S. tax season, individual federal income tax returns for the 2025 tax year are due on April 15, 2026, for most calendar-year filers.
Key due dates
- Standard filing deadline (most people)
- April 15, 2026: Last day to file your 2025 federal individual income tax return (Form 1040) and pay any tax due if you are a calendar-year filer.
- Extension deadline
- If you file a request for an automatic extension by April 15, 2026 (for example, using Form 4868), you generally have until October 15, 2026, to file the return, but you still must pay your estimated 2025 tax by April 15 to avoid late-payment penalties.
- Weekend/holiday rule
- If April 15 ever falls on a weekend or federal holiday, the deadline moves to the next business day; in 2026, April 15 is scheduled as the standard due date.
Other situations to keep in mind
- Self-employed / freelancers
- Besides the main filing deadline, self‑employed people and others who owe estimated tax usually have quarterly estimated payment deadlines (for 2026: mid‑April, mid‑June, mid‑September, and mid‑January of the following year).
- Non‑U.S. systems (example: UK, India)
- UK Self Assessment online returns for a tax year ending 5 April are typically due 31 January following the end of the tax year (for example, 31 January 2026 for the 2024–25 tax year).
* In India, the due date to file an individual income tax return for FY 2025–26 (AY 2026–27) is currently stated as 31 July 2026, unless extended or a different category applies.
If your country is not the U.S., UK, or India, or if you use a fiscal year instead of a calendar year, your deadline can be different, and it is safest to check your local tax authority’s website or a qualified tax professional.
TL;DR: For U.S. individual filers on a calendar year, 2025 taxes are due April 15, 2026; with an approved extension, you can file by October 15, 2026, but you must still pay by April 15.
