Indian Stock Market Tax Guide: Capital Gains, STT, GST, and F&O Taxation

Tax in the Indian stock market is a compounding decision: where you trade (equity vs F&O), how long you hold, and how you record transactions decide a big slice of your actual returns. This guide walks through every relevant tax - long-term and short-term capital gains on equity, the special F&O taxation regime, STT, GST on brokerage, and the practical record-keeping that prevents tax-season chaos.

Equity Delivery: LTCG and STCG

  • STCG: shares held less than 12 months are short-term, taxed at 15% (plus cess)
  • LTCG: shares held over 12 months attract 10% on gains above ₹1 lakh, plus cess
  • Fully exempt: LTCG up to ₹1 lakh per year on listed equity

Delivery traders benefit from the LTCG regime; intraday style trading does not. The takeaway: holding period matters enormously for equity tax planning.

Intraday Trading: Business Income Up To 30%

Intraday equity or F&O trading income is treated as speculative business income and taxed at your slab rate (up to 30% + cess + surcharge). It is entitled to no indexation and cannot be set off against non-speculative income. Intraday losses can be set off only against speculative gains and carried forward for four assessment years.

F&O (Derivatives): The Special Regime

The F&O trade was till recently treated as non-speculative business income; under the new regime introduced for FY24 assessment, derivative trading is now classified as speculative business income effective AY 2025-26 (the residency rule and the depreciation are nuances; verify the current-year position with a CA). Key points regardless:

  • Taxed at your slab rate - for a high-income trader that is the top of the ladder
  • Expenses like brokerage, exchange charges, data, and computer depreciation are deductible (subject to the regime rules)
  • Only ~40% of the current regime was previously allowed without audit; the threshold rules now force earlier audits - verify with your CA
  • You must maintain books of account and may require a tax audit depending on turnover and the profit threshold

The takeaway: F&O traders are treated as businessmen with full books, turnover thresholds, and audit requirements. That is heavier than most realize.

STT: The Hidden Friction

Securities Transaction Tax is charged on every applicable trade - a small percentage of turnover for delivery (0.1%) and a higher one for options (0.125% on premiums in and out), futures (0.02%), and intraday equity (0.025%). It is not deductible as a business expense; it is a levy in the purchase/sale math, and in aggregate it silently erodes returns. It is also a recurring reminder that turnover-heavy strategies pay the taxman regardless of P&L.

GST on Brokerage and the Broker-Platform Stack

Brokerage is subject to 18% GST; most brokers pass platform fees, AMC, and annual maintenance charges through with GST. These are deductible expenses for an F&O/speculative trader's P&L but not for a simple equity investor. When comparing brokers, the 18% on a ₹20 platform fee is ₹3.60 - small, but multiply by 12 months and many accounts.

Setting Off Losses: The Rules That Save You

  • Speculative losses can only be set off against speculative profits and carried forward 4 years
  • Non-speculative business losses can be set off against other business income and carried forward 8 years
  • Short-term capital losses can be set off against STCG or LTCG
  • Long-term capital losses can only be set off against LTCG
  • You cannot use speculative losses to reduce salary or house property income

Practical Record-Keeping

Take a professional position: maintain a ledger where each trade logs date, instrument, quantity, price, brokerage, STT, and net P&L. Export your broker P&L statement quarterly. Aggregate the annual P&L per section (speculative vs non-speculative vs capital gains). This one habit converts tax season from a scramble into a form-fill. Most Indian brokers now provide a consolidated tax P&L report - but you remain responsible for classifying each trade.

The New Tax Regime Caveat

Under the new personal tax regime (default), several deductions are unavailable; but the slab rates are lower. Traders should run the numbers both ways: for a trader with significant expenses and lower income, the old regime with deductions can be better; for a high-income trader, the new regime often wins. Consult a CA at filing time - the decision is fast and consequential.

Timeline to File Without Panic

  • April-May: reconcile broker P&L vs your ledger
  • May: compute advance tax obligations (due quarterly)
  • July: audit check - if turnover/income thresholds apply, engage a CA before September
  • Earlier (now required): bookkeeping from the beginning of every financial year

Bottom Line

Indian stock market taxation rewards structure: hold delivery for the LTCG rate, treat intraday/F&O as a business with books and audit thresholds, deduct what the law allows, and keep the ledger from day one. The difference between a 15% and 30%+ effective rate, or a smooth audit vs a notice, is decided months before the filing deadline - not on the day you file.
