In-Depth Guide

Capital Gains Tax is levied on net profit realized from selling capital assets like shares, equity funds, debt funds, gold, or real estate. Holding period determines classification into Short-Term (STCG) or Long-Term (LTCG) gains.

How to Calculate: Step-by-Step

1. Subtract acquisition cost and transfer expenses from selling price. 2. Apply inflation indexation if selling real estate held over 24 months. 3. Apply STCG rate (e.g. 20% on equity) or LTCG rate (e.g. 12.5% on equity gains above ₹1.25 Lakh) per latest tax rules.

Worked Calculation Example

Bought equity mutual fund units for ₹2,00,000 and sold after 18 months for ₹3,50,000: - Total Profit = ₹1,50,000. - Exemption (LTCG Section 112A) = ₹1,25,000. - Taxable Gain = ₹25,000. - LTCG Tax at 12.5% = ₹3,125.
