Business tax deadlines
When are business taxes due?
Small business owners — including those who own partnerships, corporations, and certain LLCs — have some unique tax due dates to remember. The list below doesn’t cover every business tax deadline, but we’ve included some of the most important ones to remember.
- Jan. 15, 2026 – Fourth quarter estimated tax payments due for 2025.

If your business uses a fiscal year instead, your tax due date is the 15th day of the third month after the close of your tax year. For example, if your business’s fiscal year is June 1 to May 31, your business tax return due date would be Aug. 15 — three months and 15 days after May 31.

2026 tax due date FAQs
In 2026, Tax Day falls on April 15. This is the deadline for filing your taxes as a calendar year filer. The April 15 deadline applies to:
• Traditional employees who receive a W-2
• Self-employed sole proprietors, including freelancers, independent contractors, or gig workers (Schedule C)
• Retirees
• Multi-member LLCs
• Corporate returns (Form 1120)
When are business taxes due?
There are two exceptions to the April 15 tax deadline. Partnerships (Form 1065) and S corporations (Form 1120-S) must file their business returns by March 16, 2026. The deadline is typically March 15, which falls on a weekend in 2026.
Remember that corporations and multi-member LLCs must file by April 15, just like individuals.
Why is Tax Day 2026 on April 15?
The tax due date is typically April 15 unless that day falls on a weekend or a holiday. In that case, Tax Day is usually pushed back to the next business day.
What time are taxes due on the 15th?
You must file your 2025 taxes by 11:59 p.m. on April 15, 2026. This is the last day to file and pay without penalty unless you request a tax extension. Once the clock strikes midnight, you risk potential late fees and late filing penalties. If you need more time to file, you must request an extension.
Do you have to have your taxes done by April 15?
If you can’t file your income tax return by the deadline this year, you can give yourself more time by requesting an automatic tax extension. You can do this when e-filing with TaxAct® by filing IRS Form 4868 before the tax deadline. Our software walks you through the electronic filing process, helps you claim relevant tax deductions and tax credits, and assists you in filing any state extension forms, if necessary.
Can I request an extension for my business return?
Yes. If you need more time to file your business tax return, you can request a six-month extension. Partnerships, multi-member LLCs, and corporations can file an extension using IRS Form 7004. Sole proprietors and single-member LLCs will use Form 4868, just like individuals. Tax-exempt nonprofits must request a tax extension using Form 8868.
When e-filing with TaxAct, you can request an extension using either Form 7004, 4868, or 8868. Just make sure you file for an extension before the tax deadline. If you don’t file for an extension before the Tax Day due date, you risk being charged late fees and penalties.
When are taxes due with an extension?
Once you’ve filed for a tax extension, you will have until Oct. 15, 2026, to complete and file your 2025 federal tax return. Like Tax Day, the extension deadline is typically Oct. 15 unless the 15th falls on a weekend or legal holiday.
Since partnerships and S corps have an earlier tax filing due date (March 16), they also have an earlier extension due date. This year’s extended tax deadline for partnerships and S corps is Sept. 15, 2026.
Tax Tip: Filing an automatic tax extension only gives you more time to file. It does not give you more time to pay your tax bill. When you request an extension, you can estimate and pay any tax liability for 2025. However, if you expect a tax refund and don’t anticipate owing any taxes, you should be in the clear.
Does the IRS allow tax payment plans?
Yes, if you cannot pay your tax bill all at once, you can set up an IRS payment plan. Keep in mind that the IRS may charge a fee for setting up a payment plan. They may also charge interest on your unpaid balance until it is paid in full. To minimize the amount of interest and fees you owe, try to pay off your tax bill as quickly as possible.
When is the W-2 deadline?
As an employer, your deadline for sending out W-2s is Jan. 31, 2026. This means employees should expect to receive their Form W-2 by mid-February 2026.
The deadlines for filing 1099 forms can vary based on the type of 1099 form and filing method. Generally, the paper filing due date for most 1099 forms is Feb. 28, while the e-filing deadline is typically March 31. Check out our Guide to Form 1099 for a complete list of e-filing and paper due dates for all 1099 forms.
When are quarterly taxes due?
April 15 is also the payment deadline for first quarter estimated tax payments. This due date applies to those with little or no income tax withheld from their wages, such as freelancers, small business owners, and investors.
The quarterly tax due dates for 2026 are as follows:
