Capital Gains Tax Calculator for Indian Shares
Module A: Introduction & Importance
Capital gains tax on shares in India is a crucial financial consideration for every investor. Whether you’re a seasoned trader or a first-time investor, understanding how to calculate capital gains tax can significantly impact your net returns. This tax applies when you sell shares at a profit, and the rate depends on how long you’ve held the shares (holding period) and your tax regime.
The Indian Income Tax Act categorizes capital gains into two types:
- Short-Term Capital Gains (STCG): When shares are sold within 12 months of purchase
- Long-Term Capital Gains (LTCG): When shares are sold after 12 months of holding
Since April 2018, LTCG exceeding ₹1 lakh is taxed at 10% without indexation benefits. STCG is taxed at 15% regardless of your income tax slab. Our calculator helps you:
- Determine your exact holding period
- Calculate precise capital gains
- Apply correct tax rates based on current laws
- Account for all deductible expenses
- Compare results under old vs new tax regimes

Module C: Formula & Methodology
The calculator uses the following precise methodology aligned with Income Tax Act, 1961 provisions:
1. Holding Period Calculation
Holding Period = Sale Date – Purchase Date
Classification:
- ≤ 12 months: Short-Term Capital Asset
- > 12 months: Long-Term Capital Asset
2. Cost of Acquisition
Total Cost = (Purchase Price + Brokerage + Other Expenses)
3. Capital Gains Calculation
Capital Gains = (Sale Price – Brokerage) – Total Cost
4. Taxable Amount Determination
For LTCG:
- First ₹1,00,000 is exempt (Section 112A)
- Excess is taxable at 10% (without indexation)
For STCG:
- Full amount taxable at 15% (Section 111A)
5. Tax Calculation
Tax Amount = Taxable Amount × Applicable Rate
6. Net Amount After Tax
Net Amount = Sale Price – (Tax Amount + Brokerage + Other Expenses)
Note: The calculator automatically applies the correct tax rate based on:
- Holding period classification
- Selected tax regime
- Current financial year’s tax laws

Module F: Expert Tips
Tax Planning Strategies
- Utilize the ₹1 lakh exemption: Time your sales to stay under the LTCG exemption limit when possible
- Tax-loss harvesting: Sell losing positions to offset gains (carry forward losses for 8 years)
- Hold for long-term: Convert potential STCG (15%) to LTCG (10%) by holding >12 months
- Use ELSS funds: Invest in tax-saving mutual funds for additional Section 80C benefits
- Gift to family: Transfer shares to family members in lower tax brackets (but beware of clubbing provisions)
Common Mistakes to Avoid
- Ignoring brokerage and STT in cost calculations
- Misclassifying holding period by even one day
- Not accounting for corporate actions (bonus, splits)
- Forgetting to add sale transaction costs
- Assuming all equity investments qualify for LTCG benefits
- Not maintaining proper purchase/sale records
Documentation Requirements
Maintain these records for at least 8 years:
- Contract notes from broker
- Bank statements showing transactions
- Dematerialization statements
- Proof of expenses (brokerage, STT)
- Corporate action records
- Previous years’ ITR acknowledgments
Special Cases
- Inherited shares: Cost = FMV on date of inheritance
- Gifted shares: Cost = Previous owner’s cost (if no consideration)
- ESOPs: Taxed as perquisite at exercise, then capital gains on sale
- REITs/InvITs: Different tax treatment (10% LTCG without exemption)
- Foreign shares: Taxed as per DTAA provisions
Module G: Interactive FAQ
How is the 12-month holding period calculated exactly?
The holding period is calculated from the date of acquisition to the date of transfer (sale). Both dates are inclusive. For example:
- Purchase on 15-Mar-2023, Sale on 14-Mar-2024 = 365 days (STCG)
- Purchase on 15-Mar-2023, Sale on 15-Mar-2024 = 366 days (LTCG)
For bonus shares, the holding period starts from the date of allotment, not the original purchase date.
Can I set off capital losses against other income?
No, capital losses can only be set off against capital gains. However:
- STCL can be set off against both STCG and LTCG
- LTCL can only be set off against LTCG
- Unabsorbed losses can be carried forward for 8 assessment years
- Losses must be disclosed in ITR to carry forward
Pro tip: File your return before due date to carry forward losses even if you have no taxable income.
How does STT (Securities Transaction Tax) affect my capital gains?
STT is deductible from your taxable capital gains. Key points:
- STT paid on purchase: Added to cost of acquisition
- STT paid on sale: Deductible from sale consideration
- Current STT rates: 0.01% on delivery trades, 0.025% on intraday
- STT proof is required during assessments
Our calculator automatically accounts for STT when you include it in “Other Expenses”.
What’s the difference between old and new tax regimes for capital gains?
The tax rates for capital gains remain identical in both regimes:
- STCG: 15% in both regimes
- LTCG: 10% above ₹1 lakh in both regimes
However, the choice affects:
- Your overall tax liability from other income sources
- Availability of Chapter VI-A deductions (80C, 80D etc.)
- Surcharge rates for high-income individuals
Use our calculator to compare which regime gives better overall tax savings.
How are capital gains from foreign shares taxed in India?
Foreign shares are taxed differently:
- No STT benefit (Section 112A doesn’t apply)
- STCG: Taxed at slab rates (can go up to 30%)
- LTCG: 20% with indexation benefit
- No ₹1 lakh exemption for LTCG
- Foreign tax credit available if taxed abroad
Example: Selling US stocks like Apple or Tesla would be taxed at your income tax slab rate for STCG.
What happens if I don’t report capital gains in my ITR?
Non-disclosure can lead to:
- Penalty of 50-200% of tax evaded (Section 270A)
- Interest at 1% per month (Section 234A/B/C)
- Prosecution in severe cases (Section 276C)
- Difficulty in future loan applications
- Problems with visa applications (for some countries)
The Income Tax Department receives data from stock exchanges via Annual Information Statement (AIS). Always report accurately.
How does the calculator handle corporate actions like bonuses and splits?
Our calculator uses these rules for corporate actions:
- Bonus Shares: Cost is allocated as zero; holding period starts from allotment date
- Stock Splits: Purchase price is adjusted proportionally; holding period remains same
- Rights Issues: Treated as separate acquisition at rights price
- Mergers: Cost of original shares carried forward to new entity
For precise calculations involving corporate actions, consult your broker’s consolidated account statement or a CA.
