1. Understanding Capital Gains
Capital Gains = Sale Price - Purchase Price. When you sell mutual fund units at a profit, you earn capital gains, which are taxable. The tax rate depends on holding period and fund type.
Short-Term Capital Gains (STCG)
Equity Funds
Holding period: Less than 12 months
Includes equity-oriented funds (65%+ equity)
Debt Funds
Holding period: Less than 36 months
Includes debt-oriented funds (65%+ debt)
Key Point: STCG is added to your income and taxed at your income tax slab rate
Long-Term Capital Gains (LTCG)
Equity Funds
Holding period: More than 12 months
Equity-oriented funds, ELSS
Debt Funds
Holding period: More than 36 months
Debt funds, liquid funds, FMPs
Benefit: LTCG has preferential tax rates (lower than income tax slab)
2. Tax Rates (Current FY 2025-26)
Equity Mutual Funds
STCG (<12 months)
Flat rate on short-term gains
Example:
Gain: ₹1,00,000
Tax: ₹15,000
LTCG (>12 months)
On gains above ₹1 lakh
Example:
Gain: ₹3,00,000
Exempt: ₹1,00,000
Taxable: ₹2,00,000
Tax: ₹20,000 (10% of ₹2L)
₹1 Lakh Exemption: First ₹1 lakh of LTCG per financial year is tax-free. This is per person, so a couple can claim ₹2 lakh exemption combined!
Debt Mutual Funds
Both STCG & LTCG
Post April 2023, both short-term and long-term gains from debt funds are taxed at your applicable income tax slab rate.
Example (30% tax slab):
Gain: ₹1,00,000
Tax: ₹30,000 (30% slab) + 4% cess = ₹31,200
Important: Indexation benefit has been removed for debt funds purchased after April 1, 2023.
3. How to Calculate Capital Gains Tax
Step-by-Step Calculation Example
Purchase Details
- Date: Jan 1, 2024
- Fund: Flexi Cap Fund (equity-oriented)
- Units: 1,000
- Purchase NAV: ₹50
- Investment: ₹50,000
Sale Details
- Date: Dec 1, 2025 (23 months later)
- Units Sold: 1,000
- Sale NAV: ₹70
- Sale Value: ₹70,000
Tax Calculation
Capital Gain: ₹70,000 - ₹50,000 = ₹20,000
Holding Period: 23 months → LTCG (more than 12 months)
LTCG Exemption: ₹1,00,000 (annual limit)
Taxable Gain: ₹20,000 - ₹1,00,000 = Nil (fully exempt)
Tax Payable: ₹0
FIFO Method (First In First Out)
When you buy units at different times and sell partially, tax is calculated using FIFO method - units purchased first are considered sold first.
Example: Bought 100 units in Jan (₹50), 100 units in Jun (₹60). When you sell 100 units in Dec, the Jan purchase is considered sold (FIFO).
4. Tax-Loss Harvesting Strategy
Tax-loss harvesting is a legal strategy to reduce tax liability by offsetting capital gains with capital losses.
How It Works
Step 1: Identify Losses
Find underperforming funds in your portfolio that are currently in loss
Step 2: Sell Loss-Making Funds
Before financial year end (March 31), sell funds that are in loss to book the loss
Step 3: Offset Gains
Use the loss to offset capital gains from profitable funds, reducing tax liability
Step 4: Reinvest (Optional)
Immediately reinvest in similar (but not identical) fund to maintain market exposure
Real Example
Your Portfolio (March 2026):
- • Fund A: ₹2,00,000 gain (held >12 months → LTCG)
- • Fund B: ₹50,000 loss (held >12 months → LTCG loss)
Without Tax-Loss Harvesting:
- LTCG: ₹2,00,000
- Exempt: ₹1,00,000
- Taxable: ₹1,00,000
- Tax: ₹10,000 (10% of ₹1L)
With Tax-Loss Harvesting:
- Sell Fund B to book ₹50,000 loss
- Net LTCG: ₹2,00,000 - ₹50,000 = ₹1,50,000
- Exempt: ₹1,00,000
- Taxable: ₹50,000
- Tax: ₹5,000 (10% of ₹50K)
Tax Saved: ₹5,000! 💰
Important Rules
- ✓ Losses can be carried forward for 8 years
- ✓ STCG loss can offset both STCG and LTCG
- ✓ LTCG loss can only offset LTCG (not STCG)
- ✓ You can reinvest immediately (no waiting period like in USA)
- ✓ Must file ITR to carry forward losses
5. When to Sell Your Mutual Funds
✓ Good Reasons to Sell
- Goal Achievement: Selling to fund a planned financial goal
- Rebalancing: Portfolio has deviated from target allocation
- Fund Quality: Consistent underperformance vs benchmark for 3+ years
- Strategy Change: Fund manager change or investment strategy drift
- Tax Harvesting: Booking losses before year-end to offset gains
- ₹1L LTCG: Utilizing annual ₹1 lakh exemption limit
✗ Bad Reasons to Sell
- Market crash or correction (temporary volatility)
- Short-term underperformance (1-2 quarters)
- Panic selling based on news/rumors
- Following social media/friend advice blindly
- Chasing hot new NFO/fund without research
- Emergency expenses (that's why you need emergency fund!)
Tax-Efficient Selling Timeline
📅 Before 12 months: Avoid if possible (15% STCG tax)
📅 After 12 months: Preferred timing (10% LTCG only on gains > ₹1L)
📅 March (Year-end): Best time for tax-loss harvesting
📅 January-February: Plan your tax strategy, identify loss-making funds

7. Advanced Tax Optimization Strategies
Strategy 1: Annual ₹1L LTCG Harvesting
Systematically book ₹1 lakh LTCG every year (tax-free) and reinvest. This resets your cost base higher, reducing future tax liability.
Example: Portfolio value ₹10L, cost ₹8L, gain ₹2L. Sell units worth ₹1L gain before March 31. Reinvest immediately. Next year, repeat with remaining ₹1L gain.
Strategy 2: Family Member Distribution
Distribute investments across family members. Each person gets ₹1L LTCG exemption annually.
Family of 3 (you, spouse, adult child) = ₹3 lakh tax-free LTCG annually. Over 10 years = ₹30 lakhs tax-free gains!
Strategy 3: SWP (Systematic Withdrawal Plan)
Instead of lumpsum redemption, use SWP to spread withdrawals over financial years, utilizing ₹1L exemption multiple times.
Need ₹4L? Instead of redeeming ₹4L in one year (₹3L taxable), withdraw ₹1.5L over 3 years using SWP (₹1.5L tax-free).
Strategy 4: Dividend vs Growth
For equity funds, choose growth option. Dividends are added to income and taxed at slab rate. Capital gains have lower LTCG rate.
8. Common Mistakes to Avoid
Tax Mistakes
- ✗ Selling before 12 months (paying 15% STCG unnecessarily)
- ✗ Not utilizing ₹1L LTCG exemption annually
- ✗ Ignoring tax-loss harvesting opportunities
- ✗ Not filing ITR to carry forward losses
- ✗ Selling in wrong financial year
Investment Mistakes
- ✗ Letting tax tail wag investment dog (tax shouldn't be only consideration)
- ✗ Holding poor performing funds just to avoid tax
- ✗ Panic selling during market corrections
- ✗ Not maintaining purchase records
- ✗ Choosing dividend option for equity funds
Golden Rule
Tax optimization is important, but investment quality matters more.Don't hold a poorly performing fund just to avoid tax. A 30% gain with 10% tax (net 27%) is better than a 5% gain with no tax.
