Is it that unusual to run a business out of an unused bedroom or even a garage that is not being utilized?
No, it is not unusual or far-fetched. However, trading is explicitly singled out in the tax code.
If it was true that filing a schedule C as a trading business unlocks a myriad of deductions, every bubba who makes a few dozen taxable (non-retirement account) trades a year would be doing it!!
If you go this route, you must dot i's and cross T's regarding everything. It is not the same as an employer requiring you participate in zoom meetings from home!
You can't even show trading profit or loss on a schedule C... there are only workarounds subject to the ire or acceptance of the IRS.
Seek expert advise such as Green trader tax.
