This discussion clarifies the tax treatment of Nifty Futures & Options. It confirms that F&O trading is taxed under the head Profit and Gains from Business or Profession (PGBP), not Capital Gains. For PGBP, traders can opt for presumptive taxation under Section 44AD, with tax calculated at 6% of total turnover (sum of gains and losses). The 8% margin rule is not applicable here. It's also confirmed that F&O cannot be treated as capital gains.
