No matter your income level or filing status, one question unites taxpayers every year: when are taxes due 2026? Whether you’re a first-time filer, a self-employed contractor, a small business owner, or preparing on behalf of your family, understanding the tax deadlines and planning ahead is crucial to avoiding penalties and staying on track.
In this comprehensive guide, we’ll cover the most up-to-date information on federal tax due dates in 2026, including when are taxes due 2026 for individuals, extensions, estimated payments, business returns, and special circumstances like foreign filers and disasters.
Federal Tax Deadline: When Are Taxes Due 2026?
For most taxpayers in the United States, federal income tax returns for the 2025 tax year are due on April 15, 2026. This is the date by which you must file your Form 1040 and pay any federal income tax you owe to the Internal Revenue Service (IRS) to avoid penalties and interest.
Why April 15?
This date has long been the standard Tax Day in the U.S., marking the end of the federal income tax filing period. If the deadline lands on a weekend or a holiday, the IRS may adjust it to the next business day, but for 2026, April 15 is the firm deadline.
Extended Filing Deadline: October 15, 2026
If you’re not able to file by April 15, 2026, you can request an extension using IRS Form 4868, which gives you until October 15, 2026 to file your return. However, an extension to file is not an extension to pay — you must still pay any tax due by April 15 to avoid penalties and interest.

Business Tax Deadlines in 2026

C Corporations & Estates
- Due April 15, 2026 — Corporations filing Form 1120 and estates/trusts filing Form 1041 generally follow the same timeline as individuals unless otherwise specified.

Special Circumstances: Foreign Filers & State Taxes
Americans Abroad
Taxpayers living outside the U.S. on April 15, 2026, receive an automatic extension to June 15, 2026 to file their returns, although any tax owed is still due by the April 15 deadline. This grace period helps those completing paperwork from abroad without penalty.
State Tax Deadlines
Many states align with the federal deadline of April 15, 2026, but each state sets its own rules and may have different dates for state income tax returns and payments. Always check with your state’s department of revenue for details.
What Happens If You Miss the Tax Deadline?
Failing to file taxes or pay what you owe by the 2026 tax deadline can result in penalties and interest:
- Late filing penalty: If you file after April 15 without an extension, you may face penalties.
- Late payment penalty: Owing tax after the due date accrues interest and potential penalties even if you file on time.
- Penalty relief options: In some cases — such as qualifying first-time penalty abatement — you may be able to reduce penalties. For specifics, refer to the IRS’s official guidance or consult a tax professional.
