Capital gains tax is the one area where Indian retail investors consistently make costly mistakes — not from illegal evasion, but from misunderstanding the rules. Many investors do not know the difference between LTCG and STCG. Many do not know that F&O income is taxed as business income at slab rates. Many have never used tax loss harvesting to reduce their liability legally. This BBS guide covers every capital gains scenario relevant to Indian stock market investors, with the current rates post-Budget 2024, calculation examples, and the legal strategies to minimise what you pay.
The Basics: What Is a Capital Gain?
A capital gain arises when you sell a capital asset (stocks, mutual funds, real estate, gold) for more than you paid for it. The gain is the difference between the sale price and the cost of acquisition (what you paid, including brokerage). Capital gains on listed equity shares and equity mutual funds are split into two types based on how long you held the asset before selling. Short-Term Capital Gain (STCG): held for 12 months or less before selling. Long-Term Capital Gain (LTCG): held for more than 12 months before selling. This 12-month threshold applies specifically to listed equity shares and equity-oriented mutual funds. Other assets have different holding period thresholds — real estate (24 months for LTCG), debt mutual funds (treated as short-term regardless of holding period since April 2023), and unlisted shares (24 months).
Current Tax Rates (Post Budget 2024 — Effective July 23, 2024)
The Union Budget 2024 (presented July 23, 2024) changed equity capital gains tax rates significantly. These rates now apply to all equity transactions. LTCG on listed equity and equity mutual funds: taxed at 12.5% (flat, no indexation benefit) on gains above ₹1.25 lakh per financial year. Gains up to ₹1.25 lakh are completely exempt. STCG on listed equity and equity mutual funds: taxed at 20% (flat rate, regardless of your income tax slab). Previously 15% — this was increased in Budget 2024. Securities Transaction Tax (STT): STT is charged at the time of every equity trade (0.1% on delivery buy + sell, 0.025% on intraday sell) and is separate from capital gains tax. You cannot deduct STT from capital gains but you can claim it as a business expense if you are a trader. Surcharge: For very high earners, surcharge applies on LTCG — the maximum LTCG effective rate (including surcharge and cess) is 14.3% for income above ₹5 crore. For STCG the effective maximum is 23.92%.
- LTCG on equity (held >12 months): 12.5% on gains above ₹1.25 lakh/year
- STCG on equity (held ≤12 months): 20% (flat, all gains taxable)
- F&O income: Slab rate (treated as business income, not capital gains)
- Intraday trading profit: Slab rate (speculative business income)
- Debt mutual funds (any holding period): Slab rate (no LTCG benefit since April 2023)
- LTCG exemption limit: ₹1.25 lakh per financial year
- Budget 2024 effective date: July 23, 2024
How to Calculate LTCG With an Example
You bought 500 shares of Reliance Industries at ₹2,000 per share in January 2023 (total cost: ₹10,00,000). You sold all 500 shares in February 2025 at ₹3,000 per share (total sale proceeds: ₹15,00,000). Holding period: over 12 months, so this is LTCG. Gain: ₹15,00,000 − ₹10,00,000 = ₹5,00,000. LTCG exemption: ₹1,25,000. Taxable LTCG: ₹5,00,000 − ₹1,25,000 = ₹3,75,000. Tax at 12.5%: ₹3,75,000 × 12.5% = ₹46,875. Add 4% health and education cess: ₹46,875 × 1.04 = ₹48,750. Important: the ₹1.25 lakh exemption is per financial year, not per transaction. If you have multiple LTCG transactions in a year, total all gains first, subtract ₹1.25 lakh once, then apply 12.5%.
F&O Taxation: The Rule Most Traders Get Wrong
Futures and Options (F&O) income is not taxed as capital gains — it is treated as business income under the Income Tax Act, regardless of how infrequently you trade. This has several important implications. First, F&O profits are taxed at your income tax slab rate (up to 30% + surcharge + cess for high earners) — not at the flat 20% STCG rate. Second, you can deduct all business expenses from F&O income — brokerage, STT, exchange fees, advisory fees, internet, and even a portion of home office expenses if you trade from home. Third, F&O losses can be set off against F&O profits in the same year, and if the net result is a loss, it can be carried forward for 8 years to set off against future F&O profits. Fourth, you are required to file ITR-3 (business income) rather than ITR-2, and if your F&O turnover exceeds ₹1 crore, a tax audit is required. Use our BBS DCF Calculator to model your post-tax returns on any investment — accounting for LTCG, STCG, and slab rate taxes at your level changes the effective return meaningfully, especially over long holding periods.

Tax Loss Harvesting: The Legal Tax Saver Most Investors Ignore
Tax loss harvesting is the practice of selling positions that are sitting at a loss before the end of the financial year (March 31) to book those losses, which can then be set off against capital gains to reduce your tax liability. The key rules: (1) STCL (Short-Term Capital Loss) can be set off against both STCG and LTCG. (2) LTCL (Long-Term Capital Loss) can only be set off against LTCG — not against STCG or other income. (3) Both types of losses can be carried forward for 8 years if not fully utilised in the current year. Example: You have LTCG of ₹3,00,000 from selling HDFC Bank shares. You also hold Zomato shares at a loss of ₹1,50,000. If you sell Zomato before March 31, your taxable LTCG reduces to ₹1,50,000 (and after the ₹1.25 lakh exemption, only ₹25,000 is taxable). You can immediately repurchase Zomato on April 1 if you believe in the stock — there is no wash sale rule in India (unlike the US). The tax saving on ₹1,50,000 of LTCG offset: ₹1,50,000 × 12.5% = ₹18,750 — real money. Read our portfolio mistakes guide — ignoring tax loss harvesting is one of the five most common and costly errors Indian investors make. The BBS Red Flag Detector is useful for assessing the fundamental quality of positions before you harvest losses — never sell a fundamentally sound business for a tax benefit if it means missing a recovery.
The ₹1.25 Lakh Exemption Strategy
If you have substantial LTCG every year, use the ₹1.25 lakh annual exemption proactively. Each financial year, consider selling enough long-term positions to book up to ₹1.25 lakh of LTCG — completely tax-free. Immediately repurchase the same stocks. This resets your cost base higher, reducing future capital gains. If done consistently over 10 years on a growing portfolio, this strategy can save ₹15,000-20,000 per year in LTCG tax — a cumulative saving of ₹1.5-2 lakh over a decade, simply from using the exemption that already exists. This strategy is called "LTCG harvesting" — the mirror image of loss harvesting, using the exemption to book gains tax-free rather than booking losses to offset gains. Our BBS courses on personal finance and tax-efficient investing cover a complete end-of-year tax review framework — what to sell, what to hold, how to sequence transactions to minimise your total tax bill legally.
Debt Mutual Funds: The Rule That Changed in 2023
Until March 31, 2023, debt mutual funds held for more than 3 years qualified for LTCG treatment with indexation — meaning you could adjust the cost of acquisition for inflation before calculating the gain, dramatically reducing taxable profit. This benefit was removed from April 1, 2023. All gains from debt mutual funds (regardless of how long held) are now taxed at slab rates — the same as income from a fixed deposit. This makes debt mutual funds tax-equivalent to FDs for most investors, removing one of their key advantages. The implication: if you are building a fixed-income allocation in your portfolio for tax efficiency, consider instruments that still carry tax advantages — tax-free bonds (government-issued, interest is tax-exempt), PPF (EEE treatment), or ELSS funds (equity, so qualifies for LTCG treatment after 3 years).
🔍 BBS Insight
The single most impactful tax decision most long-term equity investors can make is simply to hold quality businesses for more than 12 months. The difference between STCG at 20% and LTCG at 12.5% (with ₹1.25 lakh exempt) sounds modest — but compounded over a career of investing, the tax drag on frequent trading vs patient long-term holding is enormous. A portfolio that turns over 50% every year pays STCG on half its gains; a portfolio that turns over 10% per year pays LTCG on most gains and has a dramatically higher after-tax compounding rate. The best tax advice for equity investors is also the best investing advice: buy quality businesses, understand them deeply using the BBS fundamental analysis framework, and hold long enough that the tax rate on your gains is 12.5% rather than 20%. Taxes are the one "cost" of investing that patience alone can reduce significantly.
