safe harbor available for late filing
For a pass through LLC and personal tax liability.....
At this very late date (4 days before 4/18/23 deadline)....does it make a difference to use the 2022's 4th quarter 1040-ES form to submit 110% of 2021's tax liability amount? Or should that same 110% amount be submitted with an extension request form? Would either approach reduce interest and penalties?
No taxes have yet been submitted, i.e., all four 2022 quarter payments have been missed.
Full 2022 return will not be completed until a tax professional can schedule an appointment after April 18, 2023
