extension

An extension request using IRS Form 4868 allows you to file a 2023 tax return at any time on or before October 15, 2024 without having to pay a failure to file penalty if taxes are owed.  If you have a tax refund the the 2023 tax return can be filed at any time on or before October 15,  2027 with a tax refund without penalty. 

Hello, Based on the dates in your question I believe you are talking about a business return 1065 or 1120-s.

 

Since you were late in filing you will have penalties and interest on the penalties.

 

Here is a link with the penalty amounts and also information on how to get them removed or reduced.
