Curious about the business tax deadlines that you should mark on your calendar this tax season? Here’s what small business owners need to know.
Deadlines for filing small business tax returns
There are different filing deadlines to be aware of depending on what type of business you have. Below are the key tax calendar dates to watch for in 2024.
Jan. 31, 2024
Deadline for any employees or independent contractors you hired last year to receive their W-2, 1099-NEC, or 1099-MISC tax forms.
March 15, 2024:
Deadline to file business tax returns for partnerships, S corporations, or LLCs that are taxed as partnerships (note that this is the deadline for calendar year filers). While most taxpayers fall under this category, there are special exceptions for fiscal-year taxpayers. If your tax year doesn’t start on Jan. 1, you will instead follow the IRS fiscal year due date.
Deadline to file Form 2553 to switch your business election to an S corporation (S corp) for tax year 2023. If you miss this deadline, your business will not be treated as an S corp until calendar year 2024.
April 15, 2024:
Deadline for C corporations, sole proprietorships (Schedule C), single-member LLCs or LLCs taxed as corporations, and individuals to file their tax returns.
Last day for you to make 2022 contributions to traditional and Roth IRAs.
Sept. 15, 2024:
Deadline to file your partnership or S corporation return if you requested an extension.
Oct. 15, 2024:
Deadline to file your sole proprietorship, multi-member LLC, or corporate return if you requested an extension.

How to file a tax extension as a small business owner
Not quite ready to file your taxes yet? That’s okay — if you need more time, you have until your tax-filing deadline (March 15 or April 15, 2024, depending on your business structure) to apply for a tax-filing extension. An extension will give you an extra six months to file your return.
Just remember, a tax extension only extends your filing deadline, meaning you still need to pay any estimated tax payments on your business’s tax deadline. Make sure to pay your estimated taxes on time to avoid any late fees!
