How to Calculate Long-Term Capital Gains Tax (LTCG) In India

Here are the steps you can follow to calculate your long-term capital gains (LTCG): 

• Check if it’s a long-term gain: Make sure you held the asset for the required time, like over 1 year for shares or over 2 years for property, to qualify as LTCG.
• Calculate the sale amount: This is the total money you received from selling the asset.
• Figure out the indexed purchase cost: Adjust the original purchase price for inflation using the formula:
  (Purchase Price × CII of sale year ÷ CII of purchase year).
• Add cost of improvements: Include major repair or upgrade costs, also adjusted for inflation, if any.
• Subtract selling expenses: Deduct costs like brokerage, legal fees, stamp duty, or registration charges.
• Apply the LTCG formula: Final gain = Sale Price − (Indexed Cost + Indexed Improvements + Selling Expenses).
• Calculate the tax: Pay 10% tax on gains above ₹1 lakh for stocks/mutual funds, and 20% tax with indexation for property, gold, or other assets.

Long-Term Capital Gains Tax Calculation Example

Let’s go through some examples to know how is long-term capital gains tax is calculated.

Example 1: Equity Mutual Funds

Suppose you invested ₹2,00,000 in an equity mutual fund in April 2023 and sold your units for ₹4,00,000 in May 2025, after holding them for more than 12 months.

Sale value: ₹4,00,000
Purchase value: ₹2,00,000
Capital gain: ₹4,00,000 − ₹2,00,000 = ₹2,00,000
Exempt LTCG limit: ₹1,25,000 (no tax on gains up to this amount in a financial year)
Taxable LTCG: ₹2,00,000 − ₹1,25,000 = ₹75,000
Tax payable: 12.5% of ₹75,000 = ₹9,375

Since equity gains aren’t adjusted for inflation, this is a straightforward gain-minus-exemption calculation.

Example 2: Property (With Indexation)

Suppose you bought a residential property in FY 2014-15 for ₹40,00,000 and sold it in FY 2024-25 for ₹95,00,000.

Indexed purchase cost: ₹40,00,000 × (CII of FY 2024-25 ÷ CII of FY 2014-15) = ₹40,00,000 × (363 ÷ 240) = ₹60,50,000
Capital gain (with indexation): ₹95,00,000 − ₹60,50,000 = ₹34,50,000
Tax payable: 20% of ₹34,50,000 = ₹6,90,000

Indexation adjusts your original purchase price for inflation, so you’re taxed only on the “real” gain rather than the inflated rupee gain.

How to File for Long-Term Capital Gains Tax (LTCG)

Filing for long-term capital gains tax is part of your annual tax return. Here’s how to do it correctly as per the IRS 2025 guidelines:

• Use ITR-2 or ITR-3: If you earned long-term capital gains, you need to file either ITR-2 or ITR-3 based on your income type. These forms have a special section where you report your capital gains details.

• Fill Schedule CG: In the Schedule CG section, fill in details like what you sold, when you bought and sold it, how much you earned, and the cost of purchase.

• Use AIS and Form 26AS: Check your Annual Information Statement (AIS) and Form 26AS to see if your broker or mutual fund company has reported your capital gains correctly.

• Pay Advance Tax: If your total tax (including LTCG) exceeds ₹10,000 in a year, you must pay advance tax in quarterly instalments.  
• E-Verify the Return: Submit and verify your ITR on the Income Tax e-filing portal within 30 days to complete the process.

Smart Ways To Reduce Long-Term Capital Gains Tax

Reducing your long-term capital gains tax requires careful planning and knowledge of tax-friendly strategies. Here’s what you can do:  

• Use Section 54/54F/54EC exemptions wisely: These sections let you save tax if you reinvest your gains in eligible assets like residential property or specified bonds. Make sure to follow the reinvestment timeline and asset type specified by the Income Tax Act.

• Plan sale in different financial years: You can save tax by selling equity assets in portions across financial years. This allows you to take full advantage of the ₹1 lakh LTCG exemption on listed shares and equity mutual funds each year.

• Gift assets to family members in lower tax brackets: You can transfer certain assets to family members who fall in lower or no tax slabs. When they sell the asset, the LTCG may be taxed at a lower rate or even be exempt up to ₹1 lakh in case of equities.

• Use loss harvesting at year-end to offset gains: If you have investments with losses, sell them before the financial year ends to offset gains. This helps reduce your overall capital gains tax liability legally.

• Invest in capital gain bonds under Section 54EC: You can invest your real estate gains in NHAI or REC bonds within 6 months of sale to save tax. These bonds have a 5-year lock-in and a maximum limit of ₹50 lakh per financial year.

• Reinvest in residential property under Section 54 or 54F: If you use your capital gains to buy or build a residential house, you can claim full or partial exemption. The property must be purchased within 2 years or constructed within 3 years of the sale.
