Comprehensive Guide to Capital Gains Tax on Shares (Post 31 Jan 2018)
Module A: Introduction & Importance of Capital Gains Tax Calculation
The introduction of the new capital gains tax regime on 31 January 2018 marked a significant shift in how investments in equity shares and equity-oriented mutual funds are taxed in India. This change was implemented through the Finance Act 2018, which introduced the concept of Grandfathering for shares acquired before 31 January 2018 while establishing new tax rules for shares purchased after this date.
Understanding this tax calculation is crucial because:
- Tax Efficiency: Proper calculation helps in tax planning and optimizing your investment returns
- Compliance: Accurate reporting avoids penalties and legal issues with tax authorities

The key changes introduced in 2018 include:
- Introduction of 10% Long-Term Capital Gains (LTCG) tax on gains exceeding ₹1 lakh
- Continuation of 15% Short-Term Capital Gains (STCG) tax
- Grandfathering provision for shares acquired before 31 January 2018
- Change in the definition of long-term (from 12 months to 24 months for immovable property, but remaining 12 months for shares)

Module C: Formula & Methodology Behind the Calculator
The calculator uses precise mathematical formulas based on Indian Income Tax Act provisions. Here’s the detailed methodology:
1. Holding Period Calculation
The holding period is calculated as the difference between sale date and purchase date. This determines whether the gain is short-term or long-term:
- Short-Term: Holding period ≤ 12 months
- Long-Term: Holding period > 12 months
2. Capital Gains Calculation
The basic formula for capital gains is:
Capital Gains = (Sale Price - Purchase Price) × Quantity - Brokerage/Charges
3. Taxable Amount Determination
For long-term capital gains (LTCG):
- First ₹1,00,000 of LTCG in a financial year is exempt
- Amount exceeding ₹1,00,000 is taxable at 10% (plus surcharge and cess)
For short-term capital gains (STCG):
- Entire gain is taxable at 15% (plus surcharge and cess)
4. Tax Calculation
The tax is calculated as:
New Regime:
- STCG Tax = 15% of capital gains + 4% cess
- LTCG Tax = 10% of (taxable amount - ₹1,00,000) + 4% cess
Old Regime:
- Tax is calculated based on your income tax slab rate
5. Net Profit Calculation
Net Profit = Capital Gains - Tax Liability
Important Notes:
- The calculator assumes you don’t have any other capital gains in the financial year that might affect the ₹1 lakh LTCG exemption
- Surcharge is not included as it depends on your total income (10% for income > ₹50 lakh, 15% for > ₹1 crore, etc.)
- The 4% health and education cess is included in all calculations
- For F&O trades, different tax rules apply (treated as business income)
Module D: Real-World Examples with Specific Numbers
Let’s examine three practical scenarios to understand how the tax calculation works in different situations:
Example 1: Short-Term Capital Gain (STCG)
Scenario: Ramesh purchased 100 shares of XYZ Ltd. on 15 March 2023 at ₹500 per share and sold them on 10 September 2023 at ₹650 per share. Brokerage and charges totaled ₹500.
| Parameter | Value |
|---|---|
| Purchase Date | 15 March 2023 |
| Sale Date | 10 September 2023 |
| Holding Period | 5 months 26 days (Short-term) |
| Purchase Price | ₹500 × 100 = ₹50,000 |
| Sale Price | ₹650 × 100 = ₹65,000 |
| Brokerage/Charges | ₹500 |
| Capital Gains | ₹65,000 – ₹50,000 – ₹500 = ₹14,500 |
| Tax Liability (15% + 4% cess) | ₹14,500 × 15.6% = ₹2,262 |
| Net Profit | ₹14,500 – ₹2,262 = ₹12,238 |
Example 2: Long-Term Capital Gain (LTCG) Below Exemption Limit
Scenario: Priya bought 200 shares of ABC Ltd. on 5 January 2022 at ₹300 per share and sold them on 20 January 2023 at ₹450 per share. Total charges were ₹800.
| Parameter | Value |
|---|---|
| Purchase Date | 5 January 2022 |
| Sale Date | 20 January 2023 |
| Holding Period | 1 year 15 days (Long-term) |
| Purchase Price | ₹300 × 200 = ₹60,000 |
| Sale Price | ₹450 × 200 = ₹90,000 |
| Brokerage/Charges | ₹800 |
| Capital Gains | ₹90,000 – ₹60,000 – ₹800 = ₹29,200 |
| Taxable Amount (after ₹1L exemption) | ₹0 (since ₹29,200 < ₹1,00,000) |
| Tax Liability | ₹0 |
| Net Profit | ₹29,200 |
Example 3: Long-Term Capital Gain (LTCG) Above Exemption Limit
Scenario: Anil invested in 500 shares of PQR Ltd. on 1 August 2020 at ₹200 per share and sold them on 15 August 2023 at ₹500 per share. Total transaction charges were ₹2,500. He had no other capital gains in the financial year.
| Parameter | Value |
|---|---|
| Purchase Date | 1 August 2020 |
| Sale Date | 15 August 2023 |
| Holding Period | 3 years 14 days (Long-term) |
| Purchase Price | ₹200 × 500 = ₹1,00,000 |
| Sale Price | ₹500 × 500 = ₹2,50,000 |
| Brokerage/Charges | ₹2,500 |
| Capital Gains | ₹2,50,000 – ₹1,00,000 – ₹2,500 = ₹1,47,500 |
| Taxable Amount (after ₹1L exemption) | ₹1,47,500 – ₹1,00,000 = ₹47,500 |
| Tax Liability (10% + 4% cess) | ₹47,500 × 10.4% = ₹4,940 |
| Net Profit | ₹1,47,500 – ₹4,940 = ₹1,42,560 |

Module G: Interactive FAQ on Capital Gains Tax
What is the grandfathering clause for shares purchased before 31 January 2018?
The grandfathering clause protects investors from the new LTCG tax on gains accrued until 31 January 2018. For shares purchased before this date:
- The cost of acquisition is taken as the higher of:
- The actual purchase price, or
- The fair market value as on 31 January 2018 (highest price on that day)
- Only gains accruing after 31 January 2018 are subject to the 10% LTCG tax
- This provision ensures that investors aren’t taxed on notional gains that accumulated before the new tax was announced
For example, if you bought shares at ₹100 in 2016 and the price on 31 Jan 2018 was ₹150, your cost for tax calculation would be ₹150, not ₹100.
How is the holding period calculated for bonus shares or stock splits?
The holding period for bonus shares or stock splits is calculated differently:
Bonus Shares:
- The holding period starts from the date of allotment of bonus shares
- For tax purposes, the cost of bonus shares is considered ₹0
- When sold, the entire sale proceeds are considered as capital gains
Stock Splits:
- The holding period continues from the original purchase date
- The cost is adjusted proportionately (e.g., in a 1:2 split, the cost per share is halved)
- No immediate tax implications on the split itself
Rights Shares:
- If rights are renounced: Holding period starts from renouncement date
- If rights are subscribed: Holding period starts from subscription date
- Cost includes both the rights price and any amount paid for original shares
What documents are required to prove capital gains for tax filing?
To substantiate your capital gains claims, maintain these essential documents:
- Contract Notes: From your broker for both purchase and sale transactions
- Dematerialization Statements: Showing credit/debit of shares
- Bank Statements: Showing payment receipts and sale proceeds
- Annual Consolidated Account Statement: From NSDL/CDSL
- Corporate Action Statements: For bonus, splits, mergers, etc.
- Brokerage Statements: Showing all transaction charges
- Previous Year Returns: If carrying forward any losses
- Valuation Reports: For unlisted shares or complex instruments
Pro Tip: Maintain digital copies in organized folders and keep physical copies for at least 8 years (the period for which you can carry forward losses).
How are capital gains from foreign stocks taxed in India?
Capital gains from foreign stocks are taxed differently in India:
- Tax Rate: Treated as “Income from Other Sources” and taxed at your slab rate (not 15%/10% like domestic shares)
- Holding Period:
- Short-term: ≤ 24 months
- Long-term: > 24 months
- Indexation Benefit: Available for long-term gains (unlike domestic shares)
- Reporting: Must be reported in Schedule FA (Foreign Assets) of ITR if holding exceeds ₹10 lakh at any time during the year
- Double Taxation: Can claim Foreign Tax Credit (FTC) if tax was paid in the source country
- Conversion Rate: Use RBI’s TT buying rate on the date of transaction for INR conversion
Important: Failure to report foreign assets can attract penalties up to ₹10 lakh under Black Money Act.
What happens if I don’t pay capital gains tax or file incorrectly?
Non-compliance with capital gains tax provisions can lead to serious consequences:
Penalties:
- Under-reporting (Section 270A): 50% of tax sought to be evaded
- Misreporting: 200% of tax sought to be evaded

- Disclose under Vivad se Vishwas scheme if eligible
- Consult a tax professional for complex cases
How does Securities Transaction Tax (STT) affect my capital gains tax?
Securities Transaction Tax (STT) plays a crucial role in capital gains taxation:
- STCG Exemption Condition: STT must be paid on both purchase and sale for the 15% STCG rate to apply
- LTCG Exemption Condition: STT must be paid on sale for the 10% LTCG rate (with ₹1L exemption) to apply
- No STT Scenarios:
- Off-market transactions
- Gift of shares
- ESOPs (at exercise time)
- Shares received via will/inheritance
- Tax Treatment Without STT:
- Gains are taxed as “Income from Other Sources”
- Taxed at slab rates (not 15%/10%)
- No benefit of ₹1L exemption for LTCG
- STT Rates:
- 0.1% on delivery-based equity sales
- 0.01% on equity purchases
- Higher rates for F&O and intraday trades
Important: STT paid can be included in your cost of acquisition when calculating capital gains.
Are there any special provisions for senior citizens regarding capital gains tax?
Senior citizens (age 60+) and super senior citizens (age 80+) enjoy some special benefits:

- Special provisions don’t apply to NRI senior citizens
Tip: Senior citizens can combine their higher basic exemption with the ₹1L LTCG exemption for better tax planning.
