Tax Saving Investments: Fixed Income Funds

Taxes can take a significant bite out of investment returns, making it essential for investors to explore ways on how to reduce tax legally while building wealth. In India, where tax laws impact every type of investment, understanding the taxation framework can help investors structure their portfolios efficiently and reduce income tax legally without running afoul of regulations. 

While equity investments often get the spotlight for tax efficiency, debt investments provide some of the best opportunities for investors looking to reduce their tax legally. From tax-free bonds that offer completely exempt interest income to strategic long-term debt investments benefiting from preferential tax treatment, there are multiple ways to optimize tax liability while maintaining stable returns. 

This guide will walk you through the taxation of debt instruments, the smartest strategies for reducing income tax legally, and the best tax-efficient debt options available in India. Whether you’re a high-net-worth individual (HNI) seeking tax-free passive income or a conservative investor looking for stable post-tax yields, this will help you build a smarter, tax-optimized debt portfolio. 

Understanding Taxation on Investment Income

Before diving into tax-saving strategies, it’s essential to understand how different types of investment income are taxed in India. Taxation can vary depending on the nature of income—whether it comes from interest payments, dividends, or capital gains. 

Types of Taxes on Investment Income

Interest Income Taxation

• Interest earned on fixed deposits (FDs), bonds, NCDs, and RBI floating rate bonds is taxed as per the individual’s tax slab. 

• There are no exemptions or deductions available for interest income, except for senior citizens under the old tax regime, who can avail a deduction of up to ₹50,000 on interest income from fixed deposits under Section 80TTB. 

Capital Gains Taxation on Debt Instruments

• If a debt investment is held for less than 24 months, it is classified as short-term capital gain (STCG) and taxed as per the investor’s tax slab. 

• If a debt investment is held for more than 24 months, it is classified as long-term capital gain (LTCG) and taxed at 12.5% with the first ₹1.25 lakh in a financial year exempted from tax. 

• The indexation benefit for debt mutual funds and other debt instruments has been removed post-July 2024. 

Tax Deducted at Source (TDS)

• TDS applies to certain debt instruments. The current thresholds for TDS are:  

• Fixed Deposits (FDs): TDS is deducted at 10% if interest income exceeds ₹40,000 (₹50,000 for senior citizens). 

• Listed Corporate Bonds: TDS is deducted at 10% if interest exceeds ₹5,000 per financial year. 

• Tax-Free Bonds: No TDS applies since the interest itself is exempt from tax. 

Taxation on Income from Equities

Dividend Taxation

• Dividends received from equity investments are taxed as per the investor’s applicable income tax slab. 

• No dividend distribution tax (DDT) is levied on companies, but investors must report and pay tax on received dividends. 

• If total dividend income exceeds ₹5,000 in a financial year, a TDS of 10% is deducted at source before payment. 

Capital Gains Taxation

• Short-Term Capital Gains (STCG): If equity shares or equity mutual funds are sold within 12 months, the gains are classified as STCG and taxed at 15%. 

• Long-Term Capital Gains (LTCG): If equity investments are held for more than 12 months, the gains are classified as LTCG and taxed at 10% beyond ₹1 lakh of gains per financial year. 

• No indexation benefit is available on equity investments.

Understanding these tax implications can help investors make informed decisions when structuring their portfolios for tax efficiency. 

How to Save Tax by Investing in Debt 

Debt investments, particularly long-term debt instruments, offer unique tax advantages compared to traditional fixed-income options like fixed deposits. Here’s why they are more tax-efficient: 

• Better Post-Tax Returns Compared to FDs: While interest on FDs as well as debt instruments is fully taxable at individual’s tax slab, LTCG on listed debt investments is taxed at only 12.5%, with an exemption on the first ₹1.25 lakh per year. Thus, debt instruments with LTCG provide better post-tax returns. 

• Tax-Free Bonds for High-Tax Brackets: Investors in the highest tax brackets can benefit significantly from tax-free bonds, which offer completely tax-exempt interest income. 

• No TDS on Tax-Free Bonds: This improves cash flow and allows investors to manage their tax liabilities better. 

By incorporating debt investments strategically, investors can significantly reduce their tax burden while maintaining a steady income stream. 

Tax Saving Debt Investment Options 

To legally reduce your tax bill, consider the following tax-efficient debt investment options: 

Tax-Free Bonds 

• Issued by government-backed entities like NHAI, PFC, and IRFC. 

• Interest income is fully exempt under Section 10(15)(iv)(h) of the Income Tax Act. 

• Best suited for investors in the 30% tax bracket looking for stable tax-free returns. 

• Example: A tax-free bond offering 5.5% post-tax return is equivalent to an FD offering 8% pre-tax (assuming a 30% tax bracket). 

Long-Term Debt Mutual Funds 

• Provide LTCG tax benefits after 24 months (post-July 2024, taxed at 12.5%). 

• Offer diversification and professional management. 

• Advantages Over FDs:  

• LTCG has lower taxation than interest on FDs, which is taxed as per slab rates. 

• Potential for higher returns compared to traditional savings. 

Infrastructure Bonds 

• Primarily used to fund infrastructure projects, providing long-term capital protection. 

• Potential Drawback: Interest is taxable. 

Non-Convertible Debentures (NCDs) & Perpetual Bonds 

• Taxation similar to debt mutual funds (LTCG after 24 months at 12.5%). 

• NCDs provide stable yields and predictable cash flow. 

• Perpetual bonds offer long-term investment opportunities but require careful selection due to credit risk. 

RBI Floating Rate Bonds 

• Interest rates are linked to government securities, providing some inflation protection. 

• TDS applies, but overall tax efficiency depends on individual tax brackets. 

Choosing the right combination of debt instruments can significantly reduce overall tax liability while ensuring stable, predictable income. 

Smart Strategies to Reduce Tax Using Debt Investments 

While choosing tax-efficient instruments is the first step, implementing smart strategies can further enhance tax savings. Here are some effective ways to legally minimize taxes while maximizing returns: 

1. Utilize the ₹1.25 Lakh LTCG Exemption 

• Investors can plan redemptions to ensure their long-term capital gains stay within the ₹1.25 lakh tax-free limit per year. 

• If investing jointly (spouse, family members), with different first holder, this exemption can be multiplied across multiple accounts. 

2. Laddering Debt Investments for Tax Efficiency 

• Instead of investing a lump sum in a single bond or FD, stagger investments across different maturities. 

• Helps manage taxable interest income and capital gains tax liability more efficiently. 

• Ensures a steady cash flow while optimizing tax benefits on LTCG-exempt thresholds. 

3. Gifting Strategy for Family Members in Lower Tax Brackets 

• Gift investments to family members (spouse, children, or parents) who fall into lower tax slabs. 

• As per Section 56(2)(x) of the Income Tax Act, gifts received from specified relatives are exempt from taxation, irrespective of the amount. 

• Capital gains and interest earned from the gifted assets will be taxed in the recipient’s hands at lower rates. 

• Ideal for HNIs looking to distribute taxable income strategically. 

4. Investing in Tax-Free Bonds for Passive Income 

• Best suited for retirees and high-net-worth individuals (HNIs) who need a steady, tax-free income. 

• These bonds provide government-backed security along with tax-free interest income. 

• No TDS deduction improves post-tax cash flow. 

5. Choosing Listed Bonds over FDs 

• Why? Interest from FDs is taxed fully, while listed corporate bonds attract LTCG tax of only 12.5% after 24 months, with a ₹1.25 lakh exemption per year. 

• High-credit-rated bonds offer similar safety but with better post-tax yields. 

6. Tax-Loss Harvesting to Offset Gains 

• Sell loss-making debt investments to offset capital gains tax from profitable ones. 

• Helps balance tax outgo in volatile market conditions. 

• Applicable to both corporate bonds and debt mutual funds. 

By integrating these strategies, investors can significantly reduce tax outflows and enhance post-tax returns on debt investments. 

Common Tax Mistakes to Avoid in Debt Investing 

Investors often make errors that increase tax liability unnecessarily. Avoid these common pitfalls: 

1. Not Considering Post-Tax Returns 

• Many investors focus solely on high pre-tax interest rates rather than post-tax returns. 

• Example: A 7.5% FD in the 30% tax bracket effectively yields only 5.25% post-tax, whereas a 6.5% tax-free bond provides a higher effective return. 

2. Selling Before 24 Months and Paying Higher Tax 

• Selling corporate bonds or debt mutual funds before 24 months leads to STCG taxed as per slab rates, which could be higher than 12.5% LTCG tax. 

• Always consider holding for the long term to take advantage of lower LTCG rates. 

3. Ignoring TDS Deduction on FDs and NCDs 

• Investors often forget about TDS deductions on corporate bonds (₹5,000 limit) and FDs (₹40,000 general, ₹50,000 for senior citizens). 

• Solution: Use tax-free bonds or tax-efficient debt options to avoid excess TDS. 

• Ensure Form 26AS is checked to claim credit for TDS. 

4. Not Factoring in Tax Law Changes 

• With indexation benefits no longer available on debt mutual funds post-July 2024, some investors may still mistakenly assume lower tax liability. 

• Regularly review Central Board of Direct Taxes (CBDT) notifications to stay updated. 

By avoiding these common mistakes, investors can significantly improve their after-tax returns and maintain compliance with tax laws. 

Conclusion & Final Tax-Saving Tips 

Debt investments offer a powerful yet often underutilized way to reduce income tax legally while ensuring stable returns. By strategically selecting tax-efficient instruments and structuring a well-balanced portfolio, investors can reduce their tax legally and enhance post-tax returns without resorting to aggressive tax-saving schemes.
