Tax Efficiency and Costs

The after-tax return is the only return that matters to you. A stock that gains 15% but you sell after one year triggers short-term capital gains tax (at your income tax slab, which could be 30% for high earners). An identical stock held for two years triggers long-term capital gains tax (20% with indexation, or 12.5% without, depending on purchase date). The same 15% gain nets to 10.5% or 13.1% depending on the hold period.

Tax-loss harvesting is a legal strategy: sell losing positions to realize the loss, offsetting gains elsewhere. If you sold winners this year and realized 2 lakh rupees in gains, selling losing stocks that generated 1 lakh rupees in losses nets your taxable gain to 1 lakh rupees. You can repurchase the sold stocks after 30 days without violating tax rules. This is free money if you'd have held those positions anyway.

Costs matter less when returns are high but compounds your drag over decades. A portfolio with 0.5% annual costs (low-cost index fund) beating a portfolio with 1.5% costs by 1% annually translates to 10% more wealth over a decade. High turnover and active trading guarantee high costs (brokerage, taxes) with no guarantee of outperformance. Minimize costs by holding for the long term, using index funds when appropriate, and keeping brokerage fees low.

In India, dividends from domestic companies held for over one year are taxed at 10% + surcharge (no indexation benefit for long-term, but still favorable to short-term gains). Debt fund gains are taxed as per your income slab if held under 3 years, or at 20% with indexation if held longer. Understand the tax treatment of each asset class and hold accordingly. A stock yielding 2% dividends in a high-tax bracket is less efficient than a stock with capital appreciation potential.

• After-tax returns are what matter; hold for long-term rates.
• Tax-loss harvest losses to offset gains.
• Costs compound; minimize trading and fees.
• Understand tax treatment of each asset class.
