2026 Tax Deadlines: Key Dates for Filers and Small Businesses
For most U.S. taxpayers, the federal tax deadline is April 15, 2026. That's the date your 2025 tax return is due. Any taxes owed must be paid, and if you need more time to file, you must submit your extension request.
April 15 is just one date on a longer calendar. If you're self-employed, a freelancer, a small business owner, or simply want to plan ahead, several other deadlines apply throughout the year.
When Are Taxes Due in 2026?
The deadline to file your 2025 federal income tax return is April 15, 2026. This date applies to most individual filers: W-2 employees, retirees, self-employed sole proprietors, and single-member LLCs.
There are two exceptions:
- U.S. citizens and resident aliens living abroad receive an automatic two-month extension to June 15, 2026, though taxes owed are still due April 15.
- Taxpayers in federally declared disaster areas may qualify for automatic IRS extensions. Check IRS Tax Relief in Disaster Situations for current relief.
If you can't file by April 15, you can request a six-month extension, which would move your filing deadline to October 15, 2026. The extension gives you more time to file, not more time to pay. Any taxes owed are still due April 15.

Frequently Asked Questions on Filing Dates and Deadlines
What happens if you miss the tax deadline?
Missing April 15 without filing an extension triggers two IRS penalties: the failure-to-file penalty and the failure-to-pay penalty. See the IRS website for more information on the types of penalties and how to avoid them.
What's the difference between the federal tax deadline and a state tax deadline?
Most states follow the federal April 15 deadline for individual income tax returns, but not all. Some states set their own deadlines, and a handful have no individual income tax at all. If you file a state return, verify your state's deadline directly with your state tax agency.
When are estimated tax payments due in 2026?
For the 2026 tax year, estimated payments for most calendar-year taxpayers are due on four dates: April 15, June 15, September 15, and January 15, 2027. These deadlines typically apply to self-employed filers, freelancers, investors, landlords, and others whose income isn't subject to sufficient withholding.
