Tax returns for trusts, and certain estates are due by April 15, 2025, for calendar year filers. A tax extension will extend the filing deadline to Oct 15th.
Tax returns for Multi Member LLC's and Partnerships are due by March 17, 2025, for calendar year filers. A tax extension will extend the filing deadline to September 15th.
If your S Corporation (Form 1120S) or Partnership/Multi-Member LLC (Form 1065) misses the March 17th tax deadline without filing a return or an extension, the IRS will impose steep late penalties.
🔹 S Corporations: A $245 penalty per shareholder, per month (or part of a month) the return is late.
🔹 Partnerships & Multi-Member LLCs: A $245 penalty per partner/member, per month (or part of a month) the return is late.
Example: If an S Corp with 3 shareholders files 2 months late, the penalty would be $245 × 3 × 2 = $1,470.
Note: The IRS charges these penalties even if no taxes are owed. Don’t risk unnecessary fees—file your extension before the deadline!
