This discussion clarifies whether a CA certificate is required for Futures & Options (F&O) trading during FY 24-25 for income tax return filing. Generally, it's not needed unless a tax audit is applicable. The applicability of a tax audit depends on turnover limits and profit margins. If turnover exceeds 3 crore but profit is declared at 6% or more, up to 10 lakh turnover, no audit is required. Losses from F&O can be shown under business income, even with high turnover, if it's the first year of trading and audit conditions aren't met.
