Attention Business Owners!
The following key tax deadlines have already passed:


1. Corporate Tax Return (Form 1120)

The deadline to file Form 1120 (C Corporations) was April 15, 2025.

  • If your business did not request an extension, you are now past due and may be accruing penalties and interest.
  • If you did request an extension, you have until October 15, 2025 to file, but the tax payment was due in April. If you didn't pay, you may also be incurring interest charges.

Recommendation:

File as soon as possible, whether or not you have an extension. The longer you wait, the greater the financial impact.

2. Partnership Tax Return
(Form 1065)

The deadline to file Form 1065 (Partnerships) was
March 17, 2025.

  • If you didn't file or request an extension, it's urgent to do so immediately to minimize penalties.
  • If you requested an extension, you have until September 15, 2025 but don't wait until the last minute.
