1. What are Capital Gains?
Capital gains occur when you sell an asset for more than its original purchase price. They are categorized based on how long you have held the investment.
- Short-Term Capital Gains (STCG): Realized when assets are sold after being held for a short period.
- Long-Term Capital Gains (LTCG): Realized when assets are held for a duration exceeding a specific threshold.
2. Holding Periods and Tax Rates (As of FY 2026-27)
| Asset Type | Holding Period | Tax Type | Tax Rate |
| Listed Shares/Equity Funds | ≤ 12 months | STCG | 20% |
| Listed Shares/Equity Funds | > 12 months | LTCG | 12.5% (on gains above ₹1.25 Lakh) |
| Debt Funds (Bought on/after 01-Apr-2023) | Any duration | N/A | Taxed at Slab Rate |
| Debt Funds (Bought before 01-Apr-2023) | > 36 months | LTCG | 20% (with Indexation) |
| Debt Funds (Bought before 01-Apr-2023) | ≤ 36 months | STCG | Taxed at Slab Rate |
Important Note: For equity-based investments, LTCG is exempt from tax up to a profit of ₹1.25 Lakh per financial year. For Debt Funds, the "Slab Rate" means your capital gains are added to your total annual income and taxed according to your applicable income tax bracket.
3. How to Calculate Capital Gains
The basic formula for calculation is:
Capital Gain = Sale Price - Purchase Price - Transfer Expenses (Brokerage, STT, etc.)
Example (Equity):
If you bought shares for ₹1,00,000 and sold them after 14 months for ₹1,50,000:
- Sale Price: ₹1,50,000
- Purchase Price: ₹1,00,000
- Total Gain: ₹50,000
- Tax Liability: Since the profit is below the ₹1.25 Lakh exemption limit, you will owe zero LTCG tax.
4. Tips to Optimize Your Taxes
- Utilize the Exemption Limit: Keep the ₹1.25 Lakh LTCG equity exemption in mind while planning your portfolio exits.
- Set-off Losses: You can offset short-term losses against short-term gains, and long-term losses against long-term gains, to reduce your overall tax burden.
- Review Legacy Investments: If you hold debt funds purchased before April 1, 2023, check your holding period. You may still be eligible for the indexation benefit, which can significantly lower your tax liability compared to the current slab-rate treatment.
5. Compliance Reminders
- Keep Records: Maintain all contract notes, brokerage statements, and mutual fund transaction reports.
- ITR Filing: Ensure that you disclose your capital gains under the correct head ("Capital Gains") when filing your Income Tax Return (ITR).
