Running a business is no small feat. You’re juggling payroll, managing expenses, and focusing on growth—only to have tax deadlines sneak up on you at the worst possible time. But here’s something many business owners overlook: your tax deadlines may not be the same as everyone else’s.
If your business operates on a fiscal-year schedule instead of the traditional calendar year, your due dates are different. And missing just one deadline? That can mean hefty penalties, IRS headaches, and unnecessary stress. Here’s what you need to know to stay ahead in 2025.
Why Your Tax Calendar Matters
Picture this: You’re laser-focused on running your business when suddenly, an IRS notice arrives in the mail. You’ve missed a tax deadline—one you didn’t even realize applied to you. Now, you’re hit with penalties and scrambling to fix it. Sound familiar?
The key to avoiding this chaos is simple: align your tax responsibilities with your business’s fiscal year and stay on top of due dates. Being proactive now can save you thousands in fines and late fees down the road.
What You Need to Know About 2025 Tax Deadlines
Personal Tax Deadlines
For individual taxpayers, the annual tax return (Form 1040 or 1040-SR) is due April 15, 2025. Unlike previous years, there are no holidays to shift the deadline, so don’t expect any extra breathing room.
If you’re required to make estimated tax payments, your quarterly installments follow this schedule:
- The first three payments are due on the 15th day of the fourth, sixth, and ninth months of your tax year.
- The final payment is due on the 15th day of the first month after your tax year ends.
Corporate Tax Deadlines
For C Corporations (Form 1120), the filing deadline is the 15th day of the fourth month after the close of your tax year.
For S Corporations (Form 1120-S), your tax return is due on the 15th day of the third month after your tax year ends. Each shareholder must also receive a Schedule K-1, which details their share of income, deductions, and credits.
Corporations making quarterly estimated tax payments must follow this schedule: the 15th day of the fourth, sixth, ninth, and 12th months of the corporation’s tax year.
Thinking about switching to an S Corporation? Make sure you file Form 2553 by the 15th day of the third month of the year you want the election to take effect. Filing in advance can ensure a smoother transition.
Partnership Tax Deadlines
For partnerships filing Form 1065, your return is due on the 15th day of the third month after your tax year ends. Each partner must also receive a Schedule K-1 or equivalent document detailing their portion of income, deductions, and credits.
Avoiding the Stress of Missed Deadlines
Nothing ruins a good day faster than an IRS penalty notice. One missed deadline can cost you big, especially when you’re managing personal taxes, estimated payments, corporate returns, and business partnerships all at once.
