The Union Budget 2024 introduced significant changes to the taxation of equity investments, including Nifty 50 index funds. These changes have altered the landscape for investors, impacting both short-term and long-term capital gains taxation. While the government has raised the tax-free exemption limit for long-term capital gains (LTCG) to Rs. 1.25 lakh per financial year, it has also increased tax rates for both short-term and long-term gains.
For investors in Nifty 50 index funds, these changes necessitate a reevaluation of strategies to maximise post-tax returns.

Understanding index funds
Index funds are mutual fund schemes that seek to replicate the performance of a specific market index by investing in its constituent securities in similar proportions as the index. Examples include schemes tracking indices such as the Nifty 50 or BSE Sensex.
The objective is to provide returns that mirror the performance of the benchmark index, subject to tracking difference, which refers to the difference between the benchmark’s return and the fund’s return. It may arise from the expense ratio, cash holdings, transaction costs and other operational factors.
Unlike actively managed mutual funds, where the fund manager has greater discretion in selecting and changing securities, index funds mirror their benchmark index.
How are Nifty 50 index funds taxed?
Two types of tax apply to Nifty 50 index funds: tax on capital gains and tax on IDCW income.
Capital gains tax
A capital gain arises when you redeem your units for more than their purchase cost. These are divided into short-term and long-term capital gains, depending on how long the investments were held before redemption, and taxed as follows:
- Short-term capital gains: If the units were held for 12 months or less, the gain is taxed at 20%.
- Long-term capital gains: If the units were held for more than 12 months, aggregate capital gains of up to ₹1.25 lakh on all eligible investments a financial year are tax-exempt. Thereon, gains are taxed at 12.5%
Surcharge and 4% health and education cess are additional.
Taxation on SIP in Nifty 50 index funds
Each SIP instalment is paid on a different date and purchases a certain set of units. When you redeem funds, the units bought first are treated as being sold first. This is known as the First In First Out (FIFO) method. The purchase date of these units determines whether the gain is short term or long term.
Tax on IDCW income
IDCW payouts are added to your taxable income and taxed at your applicable slab rate. For resident investors, TDS at 10% applies if the total IDCW paid or credited by a mutual fund exceeds ₹10,000 during a tax year. The TDS deducted can be claimed while filing the income tax return.
How to calculate tax on Nifty 50 index fund investments?
Deduct any TDS paid by the fund house on dividends before computing final liability.
Determine holding period
Identify whether your investment qualifies as short-term (less than one year) or long-term (more than one year).
Calculate capital gains
- Subtract the purchase price from the selling price.
- For LTCG, deduct Rs. 1.25 lakh (if applicable) before applying the tax rate of 12.5%.
- For STCG, apply a flat rate of 20%.
Include IDCW income
Add any IDCW payouts (if applicable) received during the financial year to your total taxable income.
Apply your applicable income tax slab rate to calculate dividend tax liability.
Account for TDS
Nifty 50 index fund tax saving strategies
- Hold a long investment horizon: Hold on to your units for at least a year to qualify for the relatively lower LTCG tax.
- Leverage the LTCG exemption limit: The exemption limit for LTCG has been raised from Rs. 1 lakh to Rs. 1.25 lakh per financial year. By strategically realising gains below this threshold each year, you can effectively reduce or eliminate LTCG tax liability.
- Opt for growth plans over IDCW plans: Growth plans reinvest earnings back into the fund. This not only enhances growth potential but also avoids the slab-rate taxation applicable to IDCW payouts.
- Focus on long-term investments: Holding your investments for more than one year qualifies them for LTCG taxation at a lower rate (12.5%) compared to STCG (20%).
- Tax loss harvesting: This involves selling investments at a loss to offset taxable capital gains, reducing your tax liability. You can reinvest in a similar asset to stay invested while still benefiting from the tax savings.
Why to invest in Nifty 50 index funds?
Some factors that may influence an investor’s decision include:
- Exposure to established large-cap companies: Nifty 50 index funds provide exposure to 50 large and liquid companies listed on the NSE. These companies represent several important sectors of the Indian economy.
- Market-linked returns: The fund seeks to track the performance of the Nifty 50, subject to expenses and tracking difference. Its returns rise or fall with the index and are not fixed or assured.
- Diversification within the index: Instead of investing in a single company, investors gain exposure to 50 companies across multiple sectors. However, the stocks do not have equal weights, and companies with a higher free-float market capitalisation have a greater influence on the index.
- Rules-based portfolio construction: The fund follows the Nifty 50 methodology rather than relying on the fund manager to select stocks. Its portfolio is adjusted when the index is rebalanced or its constituents and weights change.
- Transparency: The Nifty 50 constituents, their weights and the index methodology are publicly available. This allows investors to see which companies the fund seeks to hold and how the index is constructed.
Conclusion
As an investor in Nifty 50 index funds, it’s essential to adapt your strategies in light of these changes—whether by holding investments longer, opting for growth plans over dividends, or leveraging exemptions effectively. Diversifying across asset classes may also help mitigate higher equity taxation while maintaining portfolio efficiency.
