Filed an extension?
Your real deadline is coming.
Business and personal extended returns are due on two different dates this year. Missing either one restarts the penalty clock — here's exactly what to mark on your calendar.
BUSINESS EXTENTION
SEP 15
2026
Partnerships & S-Corporations
Form 1065 / Form 1120-s filed on extension via Form 7004
PERSONAL & C-CORP EXTENSION
2026
OCT 15
Individuals & C-Corporations
Form 1040 / Form 1120 filed on extension via Form 4868 / 7004
1
File your complete, extended return by your deadline — no further extensions are available.
2
Pay any remaining balance owed — extensions delay paperwork, not payment.
3
Confirm K-1s and supporting docs are in before your preparer's cutoff
Remember: an extension moves your filing date, not your payment date. Interest and late-payment penalties have been accruing since April 15 on any unpaid balance.
Let's get it filed right — before the deadline finds you.

Dates apply to calendar-year filers for the 2025 tax year. Fiscal-year businesses, trusts, estates, and nonprofits follow different schedules — ask us if you're unsure which applies to you. This flyer is for general awareness and isn't tax advice for your specific situation.
