Dear Sir,
Hope you are doing well !!
The single most important reason to file with F&O trading is to be able to benefit from losses you have incurred. If your business resulted in a loss, don’t worry, report it in your tax return. It can be adjusted from income from remaining heads such as rental income or interest income (cannot be adjusted from salary income). Any unadjusted loss can be carried forward for eight years. However, in the future, they can only be adjusted from non-speculative income. F&O trading loss is considered a non-speculative loss. Intra-day stock trading is considered as a speculative loss. And it can only be adjusted against speculative income. Unadjusted speculative losses can be carried forward to four years.
Apart from that, you can take the benefit of section presumptive taxation scheme.
Maintenance of books of account and Tax audit u/s 44AB of income tax is mandatory in case turnover from F&O transactions exceeds Rs. 2 Crore irrespective of loss or profit.
