Tax-Loss Harvesting in India: A Strategic Guide for Equity Investors
Tax-loss harvesting is a portfolio management strategy where investors intentionally sell underperforming investments at a loss to offset capital gains realised from profitable investments. By reducing the net taxable capital gains, investors can lower their tax liability without fundamentally altering their investment thesis. In India, the strategy has become increasingly relevant and widely practised following the reintroduction of LTCG tax on equity in 2018 and the subsequent rate increases in Budget 2024 — which raised LTCG to 12.5% and STCG to 20% for listed equity.
A closely related and equally powerful strategy specific to the Indian tax context is LTCG exemption harvesting — booking gains up to the Rs 1.25 lakh annual exemption threshold tax-free and immediately reinvesting at the higher current price. Unlike the United States where a "wash-sale rule" disallows loss benefits if the same security is repurchased within 30 days, India has no such restriction. Indian investors can sell an equity fund or stock and buy back the same instrument the same day, legally capturing both loss harvesting and gain harvesting benefits.
How Capital Gains Are Taxed on Equity in India for FY 2025-26
Under the Finance Act 2024 (effective 23 July 2024), equity capital gains tax rates in India are:
Long-Term Capital Gains (LTCG): 12.5% on gains exceeding Rs 1,25,000 per financial year from listed equity shares and equity-oriented mutual funds held for more than 12 months. A 4% cess applies. Surcharge is capped at 15% for LTCG under Section 112A regardless of total income.
Short-Term Capital Gains (STCG): 20% on gains from listed equity held for 12 months or less. A 4% cess applies. Normal surcharge slabs apply to STCG.
At these rates, the tax impact of capital gains is meaningful for active investors. On Rs 5 lakh of equity LTCG (above exemption), the tax is Rs 46,875 plus Rs 1,875 cess = Rs 48,750. On Rs 2 lakh of STCG, tax is Rs 41,600 including cess. Strategic harvesting that eliminates or reduces these liabilities creates real, measurable wealth.
LTCG Exemption Harvesting: The Indian Investor's Unique Advantage
The Rs 1.25 lakh annual LTCG exemption is one of the most powerful tax planning tools available to Indian equity investors — and one of the most underutilised. Every financial year, each taxpayer can realise up to Rs 1.25 lakh of equity LTCG completely tax-free. By systematically harvesting this exemption annually, investors can reset the cost basis of their portfolio progressively, reducing future taxable gains.
Here is how the annual harvesting strategy works in practice: In March of each financial year, review your long-term equity portfolio for positions with unrealised LTCG. Sell units or shares to book exactly Rs 1.25 lakh in gains — the full exempt amount — and on the same day (or the next trading day), repurchase the identical fund or shares at the current price. Your new cost basis is the repurchase price (higher than your original cost). In future years, when you eventually exit the investment, the gain calculated from the reset cost basis is lower, reducing future LTCG tax.
Over a 10-year investment career, annual harvesting of Rs 1.25 lakh saves approximately Rs 1.56 lakh in tax (12.5% of Rs 12.5 lakh at current rates, not accounting for tax on tax savings over time). The actual saving in present value terms — since you are deferring the tax on the reset gains to future years when you actually sell — can be substantially higher.
Loss Harvesting: Set-Off Rules and Strategy
The Income Tax Act prescribes specific rules for setting off capital losses against capital gains. Understanding these rules is the foundation of effective tax-loss harvesting:
Short-Term Capital Loss (STCL): Can be set off against both STCG and LTCG in the same year. STCL is more versatile — it addresses both categories of gain. When you have significant STCG (taxed at 20%) and also unrealised short-term losses, harvesting those losses first delivers the highest per-rupee tax saving (since STCG is taxed at the higher 20% rate).
Long-Term Capital Loss (LTCL): Can only be set off against LTCG, not against STCG. If your LTCG is already within the Rs 1.25 lakh exemption (i.e., net zero LTCG tax anyway), harvesting long-term losses provides no current-year benefit — the losses can only be carried forward to offset future LTCG. In such cases, check whether those positions have been held for less than 12 months first; if they are still short-term losses, the more flexible STCL set-off applies.
Carry-Forward: Both STCL and LTCL can be carried forward for up to 8 assessment years if not fully utilised in the year of loss, subject to filing the ITR before the due date under Section 139(1). STCL carried forward can offset both STCG and LTCG in future years. LTCL carried forward can only offset LTCG in future years. This asymmetry further emphasises the value of short-term loss positions for harvesting.
Practical Example of Tax-Loss Harvesting (FY 2025-26)
An investor has the following position at the end of November FY 2025-26:
Realised LTCG from equity mutual fund redemption: Rs 4,00,000. Realised STCG from stock sale: Rs 80,000. Unrealised short-term loss in Stock X: Rs 60,000 (held 8 months). Unrealised long-term loss in Stock Y: Rs 90,000 (held 14 months).
Without harvesting: LTCG tax = 12.5% of (Rs 4,00,000 minus Rs 1,25,000) = 12.5% x Rs 2,75,000 = Rs 34,375. STCG tax = 20% x Rs 80,000 = Rs 16,000. Total before cess = Rs 50,375. After 4% cess: Rs 52,390.
With harvesting (sell Stock X and Stock Y):
STCL of Rs 60,000 offsets STCG of Rs 80,000 first: Net STCG = Rs 20,000. STCG tax = 20% x Rs 20,000 = Rs 4,000. LTCL of Rs 90,000 offsets LTCG of Rs 4,00,000: Net LTCG = Rs 3,10,000. After Rs 1,25,000 exemption: taxable LTCG = Rs 1,85,000. LTCG tax = 12.5% x Rs 1,85,000 = Rs 23,125. Total before cess = Rs 27,125. After 4% cess: Rs 28,210.
Tax saving from harvesting = Rs 52,390 minus Rs 28,210 = Rs 24,180. After estimated transaction costs of Rs 2,000 (brokerage, STT, charges on selling and repurchasing), net saving = Rs 22,180. This is a 42% reduction in capital gains tax through two targeted sell decisions.
No Wash-Sale Rule in India: The Buy-Back Freedom
Unlike the United States where the "wash-sale rule" (Section 1091 of the US Internal Revenue Code) disallows a loss if the taxpayer buys the same security within 30 days before or after the sale, India has no equivalent statutory provision. Indian investors can sell a mutual fund unit today and repurchase the identical fund at the same AMC on the same day — and the loss (or gain) is recognised for Indian income tax purposes.
This is a significant advantage. In the US, an investor who harvests a loss must wait 30 days to repurchase the same security, risking missing a market rally. In India, there is no such waiting period. However, investors should be aware that the General Anti-Avoidance Rules (GAAR) under Sections 95 to 102 of the Income Tax Act empower the tax authorities to disregard transactions that lack commercial substance and are arranged primarily to obtain a tax benefit. In practice, GAAR is applied to large, structured transactions — not to individual investors harvesting a few lakh rupees in gains. A reasonable waiting period of one to three trading days, or switching to a closely correlated but legally different security, eliminates any theoretical GAAR concern.
Transaction Costs to Account For
Every sell-and-repurchase transaction carries costs that reduce the net harvesting benefit. For equity delivery trades on Indian exchanges:
Securities Transaction Tax (STT): 0.1% on the sell side for delivery equity trades. For a Rs 5 lakh sell, STT = Rs 500. Exchange transaction charges: approximately 0.00345% (NSE) per side. SEBI turnover fees: approximately 0.0001% per side. GST on brokerage (at 18%) and on exchange charges. Stamp duty on purchases: 0.015% of transaction value. Discount broker brokerage: typically Rs 0 to Rs 20 per order flat. Full-service broker brokerage: 0.3% to 0.5% per order.
Collectively, for a typical retail investor using a discount broker, total transaction costs for a sell-and-repurchase cycle are approximately 0.2% to 0.3% of the transaction value. For a Rs 10 lakh transaction, total costs are approximately Rs 2,000 to Rs 3,000. Our calculator allows you to input a custom transaction cost percentage to see the true net-of-cost benefit for your specific situation. Harvesting is beneficial when the tax saving exceeds the transaction cost — which is almost always the case when STCG or significant LTCG is involved.
Best Time for Tax Harvesting: Year-End Strategy
The optimal window for tax harvesting is January through March, the last quarter of the Indian financial year. By this point, you have a clear picture of your total capital gains for the year — from all sources including mutual fund redemptions, stock sales, and property transactions. You can precisely calculate how much loss to harvest to maximise tax savings without leaving tax-saving opportunity on the table or over-harvesting (booking losses beyond what your gains require).
For LTCG exemption harvesting (booking gains within Rs 1.25 lakh tax-free), March is the ideal month. Sell in the last week of March, realise the gain, and repurchase on 1 April (the start of the new financial year). This maximises the time before you would need to realise gains again in the next year. If the market has moved significantly by March, you may also consider harvesting in January and again in March if gains from the January repurchase have appreciated to another Rs 1.25 lakh by year-end.
