In the quest to optimize investment returns, understanding the taxation on corporate bonds is essential for every investor. While corporate bonds are known for their relatively stable returns and lower risk profile, the real value they bring depends heavily on how they are taxed. In 2025, with evolving tax rules and growing interest in fixed-income instruments, the tax treatment of corporate bonds becomes a crucial component of financial planning. Investors who are unaware of the tax implications may inadvertently lower their overall returns by not factoring in the taxes on interest income or capital gains.
Unlike traditional savings schemes or even mutual funds, corporate bond taxation functions differently and affects both the interest earned and the gains from bond sales. For example, the interest income from corporate bonds is taxed under the “Income from Other Sources” category, subject to the investor’s applicable tax slab. Similarly, capital gains tax on the sale of corporate bonds can vary depending on the holding period. By gaining clarity on these tax rules, investors can significantly enhance their post-tax income and make more informed investment choices. Therefore, an understanding of tax implications is essential for effectively incorporating corporate bonds into an investment portfolio.
What is Taxation on Corporate Bonds and How Does it Work?
Corporate bonds are subject to taxation under two primary categories: interest income and capital gains. The way each component is taxed depends on how long the bond is held and the nature of the investor (individual or company).

Types of Bonds in India and Their Taxation
Different types of bonds in India come with varying tax implications. The following is a comparison of the same:
| Type of Bond | Interest Taxation | Capital Gains Taxation | Exemption Eligibility |
| Corporate Bonds | Taxed at slab rate | STCG: slab rate; LTCG: 20% with indexation | No |
| Government Bonds | Taxed at slab rate | STCG: slab rate; LTCG: 10% without indexation | Some exemptions |
| Tax-Free Bonds (PSUs) | Interest is tax-free | STCG: slab rate; LTCG: 10% without indexation | Yes |
| Debentures (listed) | Taxed at slab rate | STCG: slab rate; LTCG: 10% without indexation | No |
| Unlisted Bonds | Taxed at slab rate | STCG: slab rate; LTCG: 20% without indexation | No |
This table clearly distinguishes that interest from corporate bonds is taxable, while corporate bonds’ tax-free status is generally reserved only for specific PSU (public sector unit) or infrastructure bonds.
How Are Corporate Bonds Taxed in India?
Let us now discuss the taxation specifics for corporate bonds to clarify all your doubts on whether corporate bonds are taxable in India:
1. Interest Income: The interest received from corporate bonds is fully taxable under the head “Income from Other Sources” and is taxed at the applicable income tax slab rate of the investor.
In other words, the tax on interest earned from corporate bonds is levied according to the investor’s income tax slab, making it essential to factor this into post-tax return calculations.
2. Capital Gains: If bonds are sold in the secondary market, the gain arising is considered a capital gain. The taxation here depends on the holding period:
- Short-Term Capital Gains (STCG): If the bond is held for less than 36 months, any gain is added to the investor’s income and taxed at the slab rate.
- Long-Term Capital Gains (LTCG): According to the Income Tax Department, as of July 23, 2024, the Indian government revised the taxation on long-term capital gains (LTCG) from corporate bonds. Previously, gains from listed bonds held for more than 36 months were taxed at 20 per cent with the benefit of indexation. However, under the new tax regime, such gains are now taxed at a flat rate of 12.5 per cent without the benefit of indexation. This change aims to simplify the tax structure and standardize LTCG taxation across various asset classes.
TDS and Interest Income: What You Need to Know
For Indian residents:
- If interest from corporate bonds is more than Rs. 5,000 in a year, TDS (Tax Deducted at Source) is charged.
- As of the financial year 2025-26, the rate of Tax Deducted at Source (TDS) on the interest income from corporate bonds is 10 per cent, subject to the condition that the investor has provided their Permanent Account Number (PAN), as per a study conducted by Cleartax. If the PAN is not submitted, the TDS rate becomes 20 per cent. This is as per Section 194A of the Income Tax Act.
- This interest will be included as part of investors’ overall income, and they will need to pay additional tax (as and when due) depending upon their slab rate.
It is important to clarify here that when the TDS is deducted, this does not indicate that this interest is not subject to taxes. It is simply an advanced tax collection. Investors are required to declare all of their interest income when filing income tax returns.
Tax Exemptions: Are There Any?
Private corporate bonds generally do not offer tax exemptions. However, some specific government or PSU (public sector unit)-issued bonds do offer tax-free interest. These include the following-
- Tax-Free Infrastructure Bonds
- Bonds under Section 10(15) of the Income Tax Act
These bonds offer lower yields compared to corporate bonds but are attractive to high-income investors who benefit from the zero tax on interest income.
Corporate Bonds vs. Tax-Free Bonds
The following is a quick comparison of corporate bonds and tax-free bonds from a taxation standpoint:
| Feature | Corporate Bonds | Tax-Free Bonds (PSUs) |
| Interest Taxation | Taxable at slab rate | Fully Tax-Free under Sec 10(15) |
| Yield/Return | 8% to 15% (Pre-tax) | 5% to 6.5% (Post-tax) |
| Capital Gains | LTCG: 12.5% without indexation | LTCG: 10% without indexation |
| Suitability | Moderate risk, high yield | Low risk, lower yield, tax benefit |
Even though the interest of corporate bonds is taxed, their high yields definitely outdo (by some percentage) tax-free bonds post-tax, depending upon whether holding time allows the advantage of indexation.
Tax planning tips for bond investors
