I am an option trader currently trying to use the mark to market election under section 475(f). I just recently change my accounting method to mark to market with my brokerage in September 2023.
1. I was wondering if I can still be able to use 475(f) to get the loss from my trading starting from January 2023 to September 2023?
2. I was wondering as an individual day trader can I use mark to market election on my 1040 return.
3. Do we have to ask the brokerage to change to mark to market accounting in order to be qualified for this 475(f) election?
