Tax on Stock Gains Could Drop: How LTCG Changes Affect Your Portfolio

If you hold equity mutual funds or listed shares in India, you have probably heard the whispers: the government may cut the long-term capital gains (LTCG) tax on equity from 12.5%. Some of your friends are already recalculating their exit plans. Others are doing nothing and hoping for the best. The truth is that a rate cut, if it comes, will change your net returns, but how much depends on your holding period, your gain size, and whether you harvest gains in the right financial year. Most investors guess. This article gives you a method instead.

Here is a number worth sitting with. Under current rules, the first ₹1.25 lakh of long-term equity gains in a financial year is exempt, and everything above that is taxed at 12.5% plus cess. A retail investor who books ₹4 lakh of LTCG in a year pays tax on only ₹2.75 lakh, which works out to roughly ₹34,375 before cess. Shift that gain across two financial years and the bill can fall noticeably. Timing and structure matter as much as the headline rate.

In this guide, we will cover what LTCG on equity actually is today, how the ₹1.25 lakh exemption and holding periods work, a fully worked example showing before-and-after tax under a hypothetical rate cut, a comparison table across scenarios, a step-by-step method to estimate your own tax, the mistakes that cost people money, and a short FAQ. Keep the Income Tax Calculator handy as you read, because you will want to run your own numbers.

Key Takeaways

• Equity LTCG (holding over 12 months) is taxed at 12.5% on gains above ₹1.25 lakh per financial year, plus 4% cess.
• Short-term gains (held 12 months or less) are taxed at 20%, so holding period changes everything.
• A rate cut only helps if you realise gains after it takes effect. It does not retroactively reduce tax on gains you have already booked.
• The ₹1.25 lakh exemption resets every financial year (1 April to 31 March). Spreading sales across years can save real money.
• Estimate tax on a per-lot or per-fund basis using the cost of acquisition, not your total portfolio value.
• Use a proper Income Tax Calculator alongside an LTCG estimate, because your slab income can affect other taxes too.

What is LTCG tax on equity in India, and how is it calculated today?

Long-term capital gains are profits from selling a capital asset held beyond a specified period. For listed equity shares, equity-oriented mutual funds, and units of equity ETFs, the threshold is 12 months. If you sell after holding for more than a year, the gain is LTCG. Sell within 12 months and it is short-term capital gain (STCG), taxed at 20% under the current framework.

The formula is simple:

1. Sale consideration = number of units sold × selling price per unit (less brokerage and STT, which are deductible in computing the gain).
2. Cost of acquisition = number of units × purchase price per unit (for shares bought before 31 January 2018, the grandfathering rule uses the higher of actual cost and the 31 January 2018 closing price, capped at the sale price).
3. Gain = sale consideration − cost of acquisition.
4. Taxable LTCG = gain − ₹1,25,000 (applied once per financial year across all your equity LTCG).
5. Tax = taxable LTCG × 12.5%, plus 4% health and education cess.

So if the only LTCG you book in FY 2025-26 is ₹3,00,000, the taxable amount is ₹1,75,000, tax at 12.5% is ₹21,875, and with cess the total is ₹22,750.

How would a possible LTCG rate cut change my net returns?

Let us make this concrete. Suppose Priya bought ₹2,00,000 worth of an index fund in 2019. By early 2026 it is worth ₹9,00,000. Her gain is ₹7,00,000, all long-term. Here is her tax today, and under a hypothetical cut to 10% (the rate is a placeholder for illustration, not a forecast).

Current regime (12.5%):

1. Gain: ₹7,00,000
2. Less exemption: ₹1,25,000
3. Taxable LTCG: ₹5,75,000
4. Tax at 12.5%: ₹71,875
5. Cess at 4%: ₹2,875
6. Total: ₹74,750
7. Net proceeds: ₹9,00,000 − ₹74,750 = ₹8,25,250

Hypothetical regime (10%):

1. Taxable LTCG: ₹5,75,000
2. Tax at 10%: ₹57,500
3. Cess at 4%: ₹2,300
4. Total: ₹59,800
5. Net proceeds: ₹9,00,000 − ₹59,800 = ₹8,40,200

The difference is ₹14,950 on one sale. That is meaningful, but notice what drove it: the rate, not the exemption. Priya could also have spread her sale across two financial years, booking ₹3,50,000 each time, and paid tax on (₹3,50,000 − ₹1,25,000) × 2 = ₹4,50,000 total taxable gain, versus ₹5,75,000 in one year. That alone saves about ₹15,000 under the current 12.5% rate, before any rate cut.

The lesson: a rate cut is one lever. Exemption management is another, and it is available today.

Does a cut apply to gains I have already made?

Generally, tax rates apply to the financial year in which income is earned or realised. A change announced in a Budget typically takes effect from a specified date, often the start of the next financial year. Gains you realised before that date stay under the old rate unless the law says otherwise. Always confirm the effective date in the Finance Bill and the notified rules. Do not assume a retroactive benefit.

Worked example: a SIP investor's net return over 15 years

Let us bring in a real SIP scenario. Rahul earns ₹12 LPA and invests ₹5,000 per month via SIP for 15 years at an assumed 12% CAGR. Using the standard future value formula for a SIP:

FV = P × [((1 + r)^n − 1) / r] × (1 + r)

where P = ₹5,000, monthly rate r = 0.12/12 = 0.01, and n = 180 months.

1. (1.01)^180 ≈ 6.0226
2. (6.0226 − 1) / 0.01 = 502.26
3. 502.26 × 1.01 = 507.28
4. FV = ₹5,000 × 507.28 ≈ ₹25,36,400

Total invested: ₹5,000 × 180 = ₹9,00,000. Gain: about ₹16,36,400.

If Rahul redeems everything in one year, LTCG is ₹16,36,400 − ₹1,25,000 = ₹15,11,400 taxable. Tax at 12.5% is ₹1,88,925, plus cess ₹7,557, total about ₹1,96,482. His net is roughly ₹23,39,918.

Now suppose he withdraws gradually over 3 financial years, keeping gains roughly ₹5,45,000 per year. Each year's taxable LTCG is ₹4,20,000, tax ₹52,500 plus cess ₹2,100, total ₹54,600 per year, or about ₹1,63,800 across three years. That is roughly ₹32,700 less than a single-year exit, and the saving comes entirely from using three exemptions instead of one. (This ignores the time value of money and fund-level costs, so treat it as an illustration.)

Comparing your options: current tax, possible cut, and phased exits

The table below compares a hypothetical ₹6,00,000 LTCG under different scenarios. Figures assume the exemption applies once per year, and cess is 4%.

Scenario	Total LTCG	Taxable (after ₹1.25L exemption)	Tax rate	Approx. total tax incl. cess
Single year, current 12.5%	₹6,00,000	₹4,75,000	12.5%	₹61,750
Single year, hypothetical 10%	₹6,00,000	₹4,75,000	10%	₹49,400
Two years (₹3L each), current 12.5%	₹6,00,000	₹3,50,000 (2 × ₹1.75L)	12.5%	₹45,500
Two years (₹3L each), hypothetical 10%	₹6,00,000	₹3,50,000	10%	₹36,400
Single year, booked in FY with other losses set off	₹6,00,000 less ₹1,00,000 loss	₹3,75,000	12.5%	₹48,750

Two things stand out. Phasing across years is worth more than most people expect. And capital losses, when properly set off and carried forward, reduce taxable LTCG directly. Harvesting losses before March is a legitimate strategy, but only if you understand the carry-forward rules: long-term capital losses can be carried forward for eight years, and they can only be set off against future LTCG.

How do I estimate my own LTCG tax before and after a Budget change?

Here is a practical checklist you can run in about 20 minutes.

1. List every equity lot. Download your contract notes or capital gains statement from your broker and your mutual fund CAMS/KFintech statement. You need purchase date, units, and cost for each lot.
2. Separate short-term from long-term. Anything held 12 months or less is STCG. Do not mix them.
3. Estimate sale value at current NAV or market price. Use today's price as a placeholder.
4. Compute gain per lot. Gain = (price − cost) × units, minus brokerage and STT where applicable.
5. Add all LTCG for the financial year you plan to sell in. Include any other equity LTCG already booked that year.
6. Subtract ₹1,25,000 once. The exemption is shared across all equity LTCG in the year.
7. Apply the rate. Use 12.5% for the current regime. Run a second line at a hypothetical lower rate to see sensitivity.
8. Add 4% cess.
9. Compare sell-now versus sell-next-year. Factor in market risk, not just tax.

For the tax on your salary and other income, which can change your overall slab and affect things like surcharge computation, use the Income Tax Calculator. For a quick projection of how your equity corpus may grow before you sell, plug your monthly amount into the SIP Calculator. If you are weighing equity against fixed deposits, the FD Calculator gives you the pre-tax comparison, though remember FD interest is taxed at slab rates, not at LTCG rates.

Pro tip: track cost of acquisition for bonus and split adjustments

Common mistake: investors recompute cost using the original purchase price after a bonus issue or stock split, which overstates gains and overpays tax. For bonus shares, the cost of the original holding is typically apportioned across original and bonus shares, and for splits the total cost is divided across the new unit count. Check the corporate action notice, or ask your broker for the adjusted cost basis. Many people overpay because their statement shows the old cost.

Common mistakes that quietly cost retail investors money

• Ignoring the exemption timing. Booking a large gain in one year when you could split it across two.
• Confusing STCG and LTCG. Selling a lot at month 11 instead of month 13 can nearly triple the rate.
• Forgetting that the exemption is per year, not per account. Demat and mutual fund gains are aggregated.
• Using the wrong cost basis. Especially after corporate actions or for grandfathered pre-2018 holdings.
• Assuming a rate cut will apply to already-realised gains. Wait for the effective date before timing sales around it.
• Not filing ITR when you have capital gains. Even if your total income is below the taxable threshold, reporting capital gains matters.

Frequently asked questions

What is the LTCG tax rate on shares in India right now?

Long-term capital gains on listed equity shares and equity mutual funds are taxed at 12.5% plus 4% cess on gains above ₹1.25 lakh in a financial year. Holdings of 12 months or less attract short-term tax at 20%. Always check the latest Finance Act for any changes before you sell.

How do I calculate LTCG tax on mutual funds?

Subtract your total cost of acquisition from the redemption value for each lot held over 12 months, add up all long-term gains for the year, subtract ₹1,25,000, and apply 12.5% plus cess. Your fund house or CAMS/KFintech statement lists purchase cost by lot.

Will the LTCG exemption limit of ₹1.25 lakh increase?

Nothing has been officially announced that changes it. Budget proposals can alter exemptions, so watch the Union Budget and the subsequent Finance Bill. Plan on the current limit until a change is notified.

Can I set off LTCG against capital losses?

Yes. Long-term capital losses can be set off against long-term gains. Unused losses can be carried forward for up to eight years, provided you file your return on time and report the losses.

Is it better to sell equity before or after March?

It depends on your full-year gains and whether the exemption is already used. Selling across the 31 March boundary lets you use two separate ₹1.25 lakh exemptions, which can reduce total tax. Compare the two scenarios using your own numbers before deciding.

Does LTCG affect my income tax slab?

LTCG on equity is taxed at its own special rate and is not added to your slab income in the same way. However, your total income can affect surcharge and the overall picture, so run it through an Income Tax Calculator rather than assuming it is irrelevant.

Should I change my investment strategy because of a possible tax cut?

Tax should be a factor, not the driver. A 2 or 3 percentage point change in rate matters less than sticking to a sound asset allocation, rebalancing, and staying invested through market cycles. If you are planning a larger goal, the Goal Planner Calculator helps you see how tax affects your timeline.

Conclusion: plan the exit, not just the entry

Whether or not the LTCG rate is cut, the investors who keep the most money are those who plan their exits. Map your lots, separate short-term from long-term, use the ₹1.25 lakh exemption each year, and run the numbers before you sell. A possible rate cut is worth watching, but the real gains come from disciplined calculation.
