Why Your Remaining LTCG Exemption Matters
Most investors do not sell stocks in a single batch at year-end. Throughout the financial year, you may sell some long-term holdings for portfolio rebalancing, to fund expenses, or to lock in profits. Each of these sales eats into your Rs 1,25,000 LTCG exemption under Section 112A.
The problem is that many investors lose track of how much exemption they have already consumed. If you sold some equity mutual funds in July and a few stocks in November, your year-to-date realized LTCG might already be Rs 60,000 or Rs 80,000. Your remaining exemption is only Rs 65,000 or Rs 45,000. If you do not know this number, you cannot plan an effective gain harvest before March 31.
Worse, some investors assume they have the full Rs 1,25,000 available at year-end and end up overshooting when they add the gain harvest on top of earlier sales. The excess above Rs 1,25,000 is taxed at 12.5%, which defeats part of the purpose of the harvest.
The solution is simple: track your realized LTCG throughout the year. Every time you sell a long-term equity holding or redeem equity mutual fund units held for over 12 months, note the gain. Maintain a running total. Then, in February or March, calculate the remaining exemption and harvest gains precisely up to that amount.
TaxHarvestLab automates this tracking. It imports all your transactions from your broker and maintains a live LTCG counter showing exactly how much exemption you have used and how much remains. This makes year-end planning effortless.
How to Calculate Your Remaining Exemption
Calculating your remaining LTCG exemption requires adding up all realized long-term capital gains from equity and equity mutual fund sales during the current financial year (April 1 to the current date).
Step 1: List all equity sales where the holding period exceeded 12 months. Include direct stocks, equity mutual fund redemptions, and equity ETF sales.
Step 2: For each sale, calculate the LTCG using the FIFO method. The gain is the sale price minus the cost of acquisition (after applying grandfathering for pre-2018 holdings).
Step 3: Sum up all the LTCG amounts. This is your total realized LTCG for the year so far.
Step 4: Subtract from Rs 1,25,000. The result is your remaining exemption.
Example: Kavita has made three equity sales so far in FY 2025-26: - April: Sold HDFC Bank shares with Rs 35,000 LTCG - August: Redeemed SBI Bluechip Fund units with Rs 22,000 LTCG - November: Sold Infosys shares with Rs 18,000 LTCG
Total realized LTCG: Rs 35,000 + Rs 22,000 + Rs 18,000 = Rs 75,000 Remaining exemption: Rs 1,25,000 - Rs 75,000 = Rs 50,000
Kavita can still harvest Rs 50,000 in additional LTCG before March 31 without paying any tax. If she does not, she permanently loses this Rs 50,000 of tax-free room.
Important: Only LTCG from Section 112A qualifying assets count. Short-term gains, debt fund gains, and gains from unlisted shares do not consume the Section 112A exemption.
Strategies When You Have a Small Remaining Exemption
If your remaining exemption is small, say Rs 10,000 to Rs 30,000, you need to be strategic about whether gain harvesting is worth the effort.
The economics work like this: the tax saving from harvesting Rs 10,000 in LTCG is Rs 1,250 (12.5% of Rs 10,000). If your round-trip transaction cost (sell and rebuy) is Rs 300-500, the net benefit is Rs 750-950. This is still positive, so it is worth doing for most investors. However, if the remaining exemption is very small, say Rs 2,000-3,000, the tax saving (Rs 250-375) may not justify the effort and transaction costs.
As a rule of thumb, gain harvesting is worth doing if the remaining exemption is at least Rs 5,000, which saves Rs 625 in tax against typical transaction costs of Rs 200-300.
When the remaining exemption is small, focus on stocks with high per-share gains so you can harvest the right amount by selling just a few shares. If a stock has Rs 500 in unrealized LTCG per share, you only need to sell 20 shares to harvest Rs 10,000. This minimizes transaction costs compared to selling many shares of a stock with a small per-share gain.
Also consider whether your remaining exemption could be better used by not harvesting and instead letting it absorb gains from a planned portfolio sale. If you know you will sell some long-term holdings in March for rebalancing, the gains from that sale will automatically use the remaining exemption without any additional transaction.
What If You Have Already Exceeded Rs 1.25 Lakh?
If your realized LTCG for the year already exceeds Rs 1,25,000, the exemption has been fully consumed. Any additional LTCG will be taxed at 12.5%. In this situation, gain harvesting for tax-free profits is no longer applicable.
However, there are still tax planning strategies available:
Strategy 1: Tax loss harvesting. If you have unrealized losses in your portfolio, harvest them to offset the LTCG above Rs 1,25,000. For example, if your realized LTCG is Rs 2,00,000, you have Rs 75,000 above the exemption that will be taxed. If you can harvest Rs 75,000 in LTCL, the two offset each other and your net taxable LTCG is zero. Even STCL can offset the excess LTCG.
Strategy 2: Defer additional sales to the next financial year. If you are planning to sell more long-term holdings but there is no urgency, waiting until after April 1 gives you a fresh Rs 1,25,000 exemption in the new financial year. A sale in March with Rs 50,000 LTCG costs you Rs 6,250 in tax, but the same sale in April may be partially or fully covered by next year's exemption.
Strategy 3: Consider the advance tax implications. If your LTCG has already exceeded Rs 1,25,000 and your total tax liability exceeds Rs 10,000 for the year, you are required to pay advance tax. Missing advance tax installments attracts interest under Sections 234B and 234C. Plan for this liability if you have exceeded the exemption early in the year.

Tracking Exemption Usage with Multiple Brokers
Many investors today use multiple brokers. You might have a Zerodha account for direct stocks, a Groww account for mutual funds, and an Angel One account for some older holdings. Each broker's capital gains statement only shows transactions made through that platform. If you have sold long-term equity through multiple brokers, you need to aggregate the LTCG across all of them to know your true exemption usage.
This is a common blind spot. An investor might check their Zerodha capital gains report, see Rs 40,000 in LTCG, and assume they have Rs 85,000 of exemption remaining. But they forgot about the Rs 55,000 LTCG from redeeming mutual funds on Groww. Their actual remaining exemption is only Rs 30,000.
To solve this, maintain a single consolidated tracker. Every time you sell an equity holding or redeem equity mutual fund units from any broker, record the LTCG in a spreadsheet or use TaxHarvestLab, which allows you to import data from multiple brokers into a single dashboard.
The aggregation must be precise. Remember that the Rs 1,25,000 exemption is an aggregate limit across all brokers, all equity stocks, all equity mutual funds, and all equity ETFs. There is no separate exemption per broker or per asset type.
Also be aware that mutual fund houses provide their own capital gains statements (via CAMS or KFintech), which may differ slightly from your broker's report. For mutual fund redemptions, the fund house's statement is generally more reliable for cost basis and holding period information. Cross-verify if there are discrepancies.
Month-by-Month Exemption Planning
The most effective approach to LTCG exemption management is to plan month by month rather than leaving everything to March.
April to September (H1): During the first half of the financial year, focus on tracking. Note any LTCG from equity sales or mutual fund redemptions. If you make a significant sale with a large LTCG, be aware that your exemption is being consumed.
October to December (Q3): By October, review your year-to-date LTCG. If it is already close to Rs 1,25,000, you know that gain harvesting is not needed. If it is well below Rs 1,25,000, start identifying candidates for gain harvesting. Check which long-term holdings have unrealized gains and rank them by the gain amount.
January to February: This is the planning window. Calculate the remaining exemption precisely. Determine the optimal stocks and quantities to harvest. If you have loss-making holdings too, plan the loss harvest first, then the gain harvest.
March 1-25: Execute the harvest. Sell and rebuy the identified stocks. Do not wait until the last few days because settlement timelines and market holidays can catch you off guard. The last trading day before March 31 varies each year.
March 26-31: Buffer period. If something went wrong with the earlier execution (stock price moved significantly, order was not filled, etc.), use these days for adjustments. But ideally, your harvest should be complete by March 25.
TaxHarvestLab provides monthly notifications showing your LTCG progress and remaining exemption, ensuring you never miss the March 31 deadline.
Real Scenario: Optimizing a Partially Used Exemption
Let us walk through a complete real-world scenario to tie everything together.
Suresh is reviewing his portfolio on February 15, 2026. He has made the following transactions during FY 2025-26: - June 2025: Sold 200 shares of Wipro (long-term, cost Rs 380, sold at Rs 520). LTCG: 200 x Rs 140 = Rs 28,000 - October 2025: Redeemed Rs 3,00,000 of ICICI Prudential Bluechip Fund (long-term, cost Rs 2,48,000). LTCG: Rs 52,000
Total realized LTCG: Rs 80,000 Remaining exemption: Rs 1,25,000 - Rs 80,000 = Rs 45,000
Suresh's current long-term holdings with unrealized gains: - 500 shares of Reliance at cost Rs 2,200, current price Rs 2,650. Unrealized LTCG per share: Rs 450. Total: Rs 2,25,000. - 300 shares of HCL Tech at cost Rs 1,100, current price Rs 1,350. Unrealized LTCG per share: Rs 250. Total: Rs 75,000. - 100 shares of Titan at cost Rs 3,000, current price Rs 3,180. Unrealized LTCG per share: Rs 180. Total: Rs 18,000.
Suresh needs to harvest exactly Rs 45,000 in additional LTCG. He has several options: - Option A: Sell 100 shares of Reliance (Rs 45,000 LTCG). Clean and simple. - Option B: Sell 180 shares of HCL Tech (Rs 45,000 LTCG). Also works. - Option C: Sell 100 shares of Titan (Rs 18,000) plus 60 shares of HCL Tech (Rs 15,000) plus 27 shares of Reliance (Rs 12,150). Total: Rs 45,150. Close enough.
Option A is the best choice because it involves only one stock, minimizing transaction costs. Suresh sells 100 Reliance shares at Rs 2,650 and rebuys at Rs 2,651. His total LTCG for the year is Rs 1,25,000, perfectly utilizing the full exemption. Tax: Rs 0. Transaction cost: approximately Rs 200. Next year, those 100 shares have a cost basis of Rs 2,651 instead of Rs 2,200, permanently reducing future taxable gains by Rs 45,000.

Analyze My Portfolio FreeFrequently Asked Questions
How do I know how much LTCG exemption I have already used?
Add up the long-term capital gains from all equity share sales and equity mutual fund redemptions you have made during the current financial year (April 1 to date). Subtract this total from Rs 1,25,000 to get your remaining exemption. Check your broker's capital gains statement or use TaxHarvestLab for an automated calculation across all brokers.
Does STCG affect my LTCG exemption?
No. Short-term capital gains are taxed separately at 20% under Section 111A and do not consume the Rs 1,25,000 LTCG exemption under Section 112A. The exemption applies only to long-term capital gains from listed equity and equity mutual funds.
What if I accidentally harvest more LTCG than the remaining exemption?
Only the amount exceeding Rs 1,25,000 (in total for the year) is taxed at 12.5%. If you accidentally overshoot by Rs 10,000, the tax on that excess is Rs 1,250 plus cess. It is not a penalty; you simply pay the standard LTCG rate on the excess.
