Why Understanding Bond Taxation Matters
Bond investors in India often focus on yield and credit ratings while overlooking one of the most significant factors affecting actual returns: taxation. Two bonds offering the same 9% yield can deliver vastly different post-tax returns depending on their type, your holding period, and your tax bracket.
Understanding how bonds are taxed helps you make informed decisions, compare instruments on an apples-to-apples basis, and potentially save lakhs in taxes over time. This guide covers every aspect of bond taxation applicable in India as of the 2024 Union Budget amendments.
Key Takeaway
Bond taxation in India has three main components: interest income tax (at slab rate), capital gains tax (STCG or LTCG), and TDS deduction. Each bond type has slightly different treatment, so understanding the nuances is essential for effective planning.
Interest Income Taxation
Interest earned on most bonds in India is classified as "Income from Other Sources" under the Income Tax Act. This interest is added to your total income and taxed at your applicable income tax slab rate.
How Interest Is Taxed
If you hold a corporate NCD paying 9% annual interest and you fall in the 30% tax bracket (old regime), your effective post-tax return drops to approximately 6.3%. For someone in the 20% bracket, the same bond yields roughly 7.2% post-tax. This is why your tax bracket is a critical variable when evaluating bond returns.
- Cumulative bonds: Interest is accrued annually and taxable each year, even if the actual payout happens at maturity
- Regular coupon bonds: Interest is taxed in the year it is received or accrued
- Zero-coupon bonds: The discount (difference between purchase price and face value) is treated as interest income on a proportionate basis
TDS on Bond Interest
Tax Deducted at Source (TDS) at 10% is applicable when the annual interest payable by a single deductible exceeds Rs. 5,000 in a financial year. Key points regarding TDS:
- TDS is deducted at 10% if your PAN is linked; otherwise, it is deducted at 20%
- TDS is merely an advance tax payment — you can claim credit for it when filing your ITR
- For listed bonds held in demat form, TDS may not be deducted by all platforms, but the interest remains fully taxable
Form 15G and 15H
If your total income is below the basic exemption limit, you can submit Form 15G (for individuals below 60 years) or Form 15H (for senior citizens aged 60 and above) to the bond issuer or platform to request that no TDS be deducted. This prevents your money from being locked up with the government until you file your return.
Reporting in Your ITR
Bond interest income should be reported under "Income from Other Sources" in your Income Tax Return (ITR). You can use ITR-1 (Sahaj) if your total income is below Rs. 50 lakh and you have no capital gains. If you have capital gains from selling bonds, you will need ITR-2 or ITR-3. TDS details are pre-filled via Form 26AS and AIS (Annual Information Statement).
Capital Gains Tax on Bonds
When you sell a bond before maturity (or it is redeemed at a price different from your purchase price), any profit is treated as a capital gain. The tax treatment depends on whether the bond is listed or unlisted, and how long you have held it.
Listed Bonds
- Short-Term Capital Gains (STCG): If held for less than 12 months, the gain is added to your income and taxed at your slab rate
- Long-Term Capital Gains (LTCG): If held for 12 months or more, taxed at a flat rate of 12.5% without the benefit of indexation (post-2024 Budget)
Unlisted Bonds
The 2024 Union Budget simplified unlisted bond taxation significantly. Previously, unlisted bonds required a 24-month holding period to qualify as long-term. Now, the rules have been aligned:
- STCG (held < 24 months before July 2024, now < 12 months): Taxed at your slab rate
- LTCG: Taxed at 12.5% without indexation
How to Calculate Capital Gains on Bonds
Capital Gains Formula
Capital Gain = Sale Price - Purchase Price - Transfer Expenses
- Sale Price: The amount received on selling or redemption
- Purchase Price: The amount you paid to acquire the bond (cost of acquisition)
- Transfer Expenses: Brokerage, platform fees, or any other cost incurred on the sale
For bonds purchased in the secondary market at a premium (above face value), your cost of acquisition is the premium price, not the face value. Conversely, bonds bought at a discount have a lower cost basis, which may result in higher taxable gains on maturity.
Tax-Free Bonds — Section 10(15)(iv)(h)
Tax-free bonds are issued by government-backed entities and offer interest that is completely exempt from income tax under Section 10(15)(iv)(h) of the Income Tax Act. No TDS is deducted on interest from these bonds. They are especially attractive for investors in the 30% tax bracket who want predictable, tax-efficient income.
Key Issuers of Tax-Free Bonds
- NHAI — National Highways Authority of India
- IRFC — Indian Railway Finance Corporation
- PFC — Power Finance Corporation
- REC — Rural Electrification Corporation
- HUDCO — Housing and Urban Development Corporation
- NABARD — National Bank for Agriculture and Rural Development
Capital Gains Still Apply
While the interest income is tax-free, if you sell tax-free bonds in the secondary market at a profit, capital gains tax is applicable based on your holding period (STCG at slab rate or LTCG at 12.5%). Only the coupon payments enjoy tax-free status.
Tax-Equivalent Yield Calculation
To compare a tax-free bond with a taxable bond on equal terms, you need to calculate the tax-equivalent yield using this formula:
Formula
Tax-Equivalent Yield = Tax-Free Yield / (1 - Your Marginal Tax Rate)
- A tax-free bond yielding 5.5% for someone in the 30% bracket: 5.5% / (1 - 0.30) = 7.86%
- A tax-free bond yielding 5.5% for someone in the 20% bracket: 5.5% / (1 - 0.20) = 6.88%
- A tax-free bond yielding 5.5% for someone in the 5% bracket: 5.5% / (1 - 0.05) = 5.79%
As the examples above illustrate, tax-free bonds are most beneficial for high-income investors. If you are in the 5% or nil bracket, a regular taxable bond will almost always offer better returns.
Section 54EC Bonds — Save Tax on Property Sale
Section 54EC of the Income Tax Act provides an exemption from long-term capital gains arising from the sale of land or a building (or both). To claim this exemption, you must invest the capital gains amount in specified bonds within 6 months from the date of the property sale.
Key Features of 54EC Bonds
- Eligible issuers: NHAI (National Highways Authority of India) and REC (Rural Electrification Corporation)
- Maximum investment: Rs. 50 lakh per financial year
- Lock-in period: 5 years (mandatory; premature redemption is not allowed)
- Interest rate: Approximately 5% to 5.25% per annum (set by the government, varies periodically)
- Interest taxability: The interest earned on 54EC bonds is taxable at your slab rate (only the capital gains exemption is available, not the interest)
Example Scenario
You sell a property for Rs. 1.5 crore with a long-term capital gain of Rs. 40 lakh. Instead of paying 20% tax (Rs. 8 lakh), you invest Rs. 40 lakh in REC 54EC bonds. You receive approximately 5% annual interest (Rs. 2 lakh per year, taxable), but you save Rs. 8 lakh in LTCG tax. Net benefit over 5 years can be substantial.
Important Conditions
- The exemption applies only to LTCG from land and/or building — not from shares, bonds, or other assets
- If you sell or transfer the 54EC bonds before the 5-year lock-in expires, the exemption is reversed and the original capital gain becomes taxable
- You must invest within 6 months of the property transfer date — there is no extension

Old Regime vs New Tax Regime for Bond Investors
The choice between the old and new income tax regimes affects how your bond interest income is taxed. Here is what bond investors need to consider:
New Tax Regime (Default from FY 2023-24)
- Lower slab rates overall (e.g., income up to Rs. 7 lakh is tax-free with rebate)
- No deductions or exemptions available (no 80C, 80D, etc.)
- Bond interest is taxed at the applicable new regime slab rates
- The effective tax on bond interest may be lower for many investors
Old Tax Regime
- Higher slab rates but multiple deductions available
- If you have significant deductions (home loan, 80C, NPS), the old regime can be more beneficial
- Bond interest still taxed at slab rate, but your effective slab may be lower after deductions
Which Regime for Bond Investors?
If bonds form a significant portion of your income, run the numbers under both regimes. Investors without many deductions may find the new regime more favorable due to lower base rates. Investors with home loans, HRA, and 80C investments may still benefit from the old regime. Capital gains tax rates (12.5% LTCG) remain the same under both regimes.
Practical Tips for Tax-Efficient Bond Investing
Consider tax-free bonds if you are in the 30% bracket
A 5.5% tax-free yield equals 7.86% pre-tax yield. Compare this with taxable bond options before deciding.
Hold bonds for at least 12 months to qualify for LTCG
The difference between slab-rate STCG and 12.5% LTCG can be significant, especially in higher brackets.
Use 54EC bonds strategically after property sales
If you are selling land or a building with large LTCG, investing up to Rs. 50 lakh in 54EC bonds within 6 months can save substantial tax.
Submit Form 15G/15H if eligible
If your total income is below the taxable threshold, avoid TDS deductions and keep your cash flow intact by submitting these forms.
Compare post-tax yields, not pre-tax
When using BondDekho to compare bonds, always calculate the post-tax yield based on your bracket to find the most suitable option.
Frequently Asked Questions
How is bond interest income taxed in India?
Bond interest income is classified as "Income from Other Sources" and is added to your total income. It is taxed at your applicable income tax slab rate. For example, if your total income places you in the 30% bracket, bond interest is taxed at 30% plus applicable surcharge and cess.
What is the capital gains tax on bonds in India?
For listed bonds, STCG (holding period less than 12 months) is taxed at your slab rate, while LTCG (12 months or more) is taxed at a flat 12.5% without indexation. For unlisted bonds, the same 12.5% LTCG rate applies after the 2024 Budget amendments. The holding period threshold for unlisted bonds was changed from 24 months to 12 months.
Are tax-free bonds really tax-free?
The interest income from tax-free bonds (Section 10(15)(iv)(h)) is completely exempt from income tax, and no TDS is deducted. However, if you sell these bonds in the secondary market at a profit, capital gains tax applies based on your holding period. So the bonds are "tax-free" only with respect to interest payments — not capital gains from trading.
How can I save tax by investing in 54EC bonds?
You can claim exemption from LTCG tax on the sale of land or building by investing the gains (up to Rs. 50 lakh) in NHAI or REC 54EC bonds within 6 months of the sale. The bonds carry a mandatory 5-year lock-in period and offer approximately 5% to 5.25% annual interest (which is taxable).
Is TDS deducted on bond interest?
Yes, TDS at 10% is deducted when the annual interest payable by a single deductible exceeds Rs. 5,000 in a financial year. Without a PAN, TDS is deducted at 20%. You can submit Form 15G (or 15H for senior citizens) if your total income falls below the taxable threshold to avoid TDS.
