A Beginner’s Guide to Capital Gains Tax on Stocks and Mutual Funds
Congratulations! Your investments have grown, and you’ve decided to sell a portion to book your profits. It’s an exciting moment. But before you start celebrating, there’s a crucial step you can’t ignore: understanding and calculating your tax liability.
Welcome to the world of Capital Gains Tax. While it might sound intimidating, the rules are quite logical. This guide will break down exactly what you need to know.
What is a Capital Gain?
In simple terms, a capital gain is the profit you make from selling an asset for more than you paid for it. For stocks and mutual funds, the calculation is straightforward:
Capital Gain = Selling Price - Purchase Price
The amount of tax you pay on this gain depends entirely on one critical factor: your holding period.
The Holding Period: Why It’s The Most Important Rule
The Income Tax Department categorizes your gains based on how long you held the investment before selling. This determines whether your profit is considered Short-Term or Long-Term, each with very different tax rules.
Let’s look at the rules for the two main types of investments: Equity and Debt.
1. For Equity Investments (Stocks & Equity Mutual Funds)
These are investments where over 65% of the portfolio is in stocks.
Short-Term Capital Gains (STCG)
- Holding Period: You sell your shares or mutual fund units within 12 months (one year) of buying them.
- Tax Rate: The profit is taxed at a flat rate of 15%, regardless of your income tax slab.
Long-Term Capital Gains (LTCG)
- Holding Period: You sell your shares or mutual fund units after holding them for more than 12 months.
- Tax Rate: This is where it gets interesting.
- Gains up to ₹1 lakh in a financial year are completely tax-free.
- Any gain above the ₹1 lakh limit is taxed at a flat rate of 10%.
Example: You invested in an equity mutual fund and made a long-term profit of ₹1,60,000.
- First ₹1,00,000 is tax-exempt.
- You only pay tax on the remaining ₹60,000.
- Tax Payable = 10% of ₹60,000 = ₹6,000.
2. For Debt Investments (Debt Mutual Funds)
The holding period and tax rules for debt funds are different.
Short-Term Capital Gains (STCG)
- Holding Period: You sell your debt fund units within 36 months (three years) of buying them.
- Tax Rate: The gain is added to your total income and is taxed according to your individual income tax slab (e.g., 10%, 20%, or 30%).
Long-Term Capital Gains (LTCG)
- Holding Period: You sell your debt fund units after holding them for more than 36 months.
- Tax Rate: The profit is taxed at 20%, but only after a powerful benefit called Indexation.
The Magic of Indexation for Debt Funds
Indexation is the government’s way of helping you account for inflation. It allows you to adjust your purchase price upwards based on the official inflation rate, which reduces your on-paper profit and, therefore, your tax outgo.
How it works:
- The government releases a Cost Inflation Index (CII) number for every financial year.
- You adjust your purchase price using this formula:
Indexed Purchase Price = Original Price x (CII of Sale Year / CII of Purchase Year)
Example: You bought a debt fund for ₹2,00,000 in June 2020 (FY 2020-21, CII = 301). You sell it for ₹2,50,000 in August 2024 (FY 2024-25, CII = 363).
- Actual Profit: ₹2,50,000 – ₹2,00,000 = ₹50,000.
- Indexed Purchase Price: ₹2,00,000 x (363 / 301) = ₹2,41,196.
- Taxable Gain: ₹2,50,000 – ₹2,41,196 = ₹8,804.
- Tax Payable: 20% of ₹8,804 = ₹1,761.
Without indexation, your tax would have been much higher. It is the single biggest advantage of holding debt funds for the long term.
Summary of Tax Rules
| Asset Type | Holding Period | Type of Gain | Tax Rate |
|---|---|---|---|
| Equity (Stocks/MF) | ≤ 1 Year | STCG | Flat 15% |
| Equity (Stocks/MF) | > 1 Year | LTCG | 10% on gains above ₹1 Lakh |
| Debt MF | ≤ 3 Years | STCG | As per Your Income Slab |
| Debt MF | > 3 Years | LTCG | 20% after Indexation |
