Tax planning is what separates investors who keep their gains from investors who give a quarter of them back to the government. Indian stock market taxes have changed substantially since 2024 — the LTCG rate went up, the exemption limit changed, F&O classification became stricter, and Budget 2024 introduced several modifications. If you've been investing for a few years and still operating on pre-2024 tax knowledge, this guide will save you real money. Let me walk through everything for FY 2025-26 (AY 2026-27).

The four taxes every Indian investor pays

  1. Capital Gains Tax — on profit when you sell.
  2. Securities Transaction Tax (STT) — charged at the time of every buy/sell.
  3. Dividend Tax — on dividends received from stocks and mutual funds.
  4. Tax on F&O / intraday — treated as business income, taxed at slab rate.

Let me cover each in detail with examples.

1. Capital Gains Tax — STCG and LTCG

When you sell a stock or equity mutual fund at a profit, that profit is your capital gain. Tax rate depends on how long you held the investment.

Short Term Capital Gains (STCG) — held under 12 months

Tax rate (Budget 2024 onwards): 20% flat, regardless of your income tax slab. Previously 15%.

Example: You buy 100 shares of Reliance at ₹2,500 on January 1, 2026 and sell on October 1, 2026 (held 9 months) at ₹2,800. Gain = (2800 - 2500) × 100 = ₹30,000. STCG tax = 20% × 30,000 = ₹6,000. You keep ₹24,000.

Long Term Capital Gains (LTCG) — held over 12 months

Tax rate (Budget 2024 onwards): 12.5% on gains above ₹1.25 lakh per year. Previously 10% above ₹1 lakh. The exemption limit increased from ₹1 lakh to ₹1.25 lakh, but the rate increased from 10% to 12.5%.

Example: You buy 100 shares of TCS at ₹3,000 in 2023 and sell in 2026 at ₹3,800. Gain = (3800 - 3000) × 100 = ₹80,000. This is below ₹1.25 lakh annual exemption, so zero tax. But if your total LTCG across all sales in the year exceeds ₹1.25 lakh, only the excess is taxed at 12.5%.

LTCG exemption tactic
If you have unrealized long-term gains, sell up to ₹1.25 lakh worth of profit each financial year and immediately buy back. You realize the gain tax-free, reset your acquisition price higher, and pay zero tax. This is called "tax harvesting" and it's perfectly legal.

Tax planning compounds. ₹10 lakh of LTCG harvested tax-free over 10 years saves significant tax.

2. Securities Transaction Tax (STT)

STT is automatically charged on every buy and sell of listed securities. You don't file it — your broker collects it and pays the government.

Transaction typeSTT rateCharged on
Equity delivery (buy + sell)0.1% each sideTrade value
Equity intraday (sell only)0.025%Sell side only
Equity futures (sell only)0.02%Sell side
Equity options (sell only)0.10%Premium value (raised from 0.0625% in Budget 2024)
Equity options exercise0.125%Settlement price
Mutual fund redemption0.001%Sell value

STT looks small but adds up. On a ₹1 lakh delivery transaction, STT is ₹200 (buy + sell). Frequent traders pay STT thousands of times a year. It's a flat tax — no exemption, no slab benefit.

3. Dividend Tax

From April 2020 onwards, dividends are taxable at your applicable income tax slab rate, not at a fixed rate. The company also deducts TDS of 10% if dividend exceeds ₹5,000 per year per company.

Example: You receive ₹15,000 dividend from Coal India and ₹8,000 from ITC during FY 2025-26. Total dividend = ₹23,000, which adds to your total income for the year. If you're in the 20% slab, you owe 20% × 23,000 = ₹4,600. The 10% TDS already deducted (₹2,300) is adjusted against this — you owe the remaining ₹2,300 with your ITR filing.

4. F&O and intraday taxes

Critical distinction: F&O and intraday profits/losses are NOT capital gains. They are taxed differently.

Since these are business income, tax audit by a Chartered Accountant becomes mandatory if turnover exceeds ₹10 crore (digital transactions) — applicable to nearly every active F&O trader. Audit costs ₹15,000-₹50,000 a year, eating into already-thin margins. This is one reason F&O is so unforgiving for retail.

See my intraday vs delivery guide and F&O basics guide for more on this.

Mutual fund taxes (2026)

Hybrid (<65% equity)Slab rateSlab rateNo LTCG benefit
Gold ETFs / fundsSlab rateSlab rateNo LTCG benefit
International equity fundsSlab rate12.5%24 months

Critical change: from April 2023, debt mutual funds lost the indexation benefit and LTCG advantage. They're now taxed as regular income at slab rate, regardless of holding period. This made them less attractive compared to FDs and PPF for tax purposes.

Practical tax planning strategies

  1. Hold equity for over 12 months whenever possible. The difference between 20% STCG and 12.5% LTCG is huge.
  2. Harvest LTCG up to ₹1.25 lakh each year tax-free. Sell, immediately buy back, reset cost base higher.
  3. Offset short-term losses against short-term gains in the same financial year. Saves immediate tax.
  4. Long-term losses can offset only long-term gains. Plan exits accordingly.
  5. Hold dividend-paying stocks in lower-earning family member's name (spouse, parent) to use their lower slab. Use this carefully — clubbing rules apply for income transfers without consideration.
  6. ELSS funds give Section 80C deduction up to ₹1.5 lakh — useful if you're in 20%+ slab and haven't used 80C elsewhere.
  7. Keep records of every buy and sell — Zerodha Console and Groww both provide annual P&L statements that simplify ITR filing.

Filing your ITR

If you trade only equity (delivery + occasional intraday), file ITR-2. If you do F&O, file ITR-3 (business income). Forms are available on the income tax e-filing portal. Most brokers (Zerodha, Groww, Upstox) provide downloadable annual P&L and tax reports that you can import directly into the ITR form.

Capital gains are reported in Schedule CG. Dividends in Schedule OS. F&O in Schedule BP. The portal has built-in calculations, so manual computation is mostly unnecessary.

Common tax mistakes

Tax knowledge isn't glamorous, but it directly compounds your returns by reducing leakage. A 1% savings via smart tax planning, compounded over 20 years at 12% pre-tax, is worth roughly 20% extra final corpus. That's significant.

Track your trades regularly via your broker's tax reports. Consult a Chartered Accountant if you have F&O trading or income above ₹15 lakh — the fees pay for themselves in saved tax. And always file your ITR on time, even if everything is loss-making — you need it to carry forward those losses.
