Upcoming Tax Deadlines You Shouldn’t Miss

Key dates for September 2025 and who qualifies for the IRS extension to February 2026

As Q3 wraps up, it’s time to mark your calendar for some important tax deadlines:

Due by September 15, 2025:
• Q3 estimated tax payments for individuals and businesses
• Extended 2024 returns for partnerships and S-corporations
• Form 990 for nonprofits that filed for an extension

But if your county was impacted by the severe storms and flooding starting July 2, 2025, the IRS has automatically extended deadlines. Any filing or payment originally due between July 2, 2025, and February 2, 2026, now get a new deadline of February 2, 2025. This applies to:
• Extended 2024 returns (normally due Oct 15)
• Estimated tax payments due Sept 15 and Jan 15
• Payroll and excise tax filings due July 31, Oct 31, and Jan 31
• Business and nonprofit returns on extension
