Capital Gains Tax on Bonds in India: Listed vs Unlisted Rules

Imagine purchasing a listed corporate bond on an online bond platform at Rs. 980 per unit and seeing its secondary market price climb to Rs. 1,040 eighteen months later as benchmark interest rates soften. If you sell that bond on the exchange prior to maturity, how is your Rs. 60 profit taxed? Does the Income Tax Act treat it the same way as an equity share, a debt mutual fund, or an unlisted debenture?

Navigating fixed-income taxation in India requires distinguishing between periodic interest earnings and capital gains realised upon sale or transfer. While regular coupon payments follow marginal income tax slabs, capital gains rules hinge heavily on listing status, holding duration, and recent legislative amendments.

This guide breaks down the framework governing capital gains tax on bonds in India. We examine the statutory holding periods for listed versus unlisted debt securities, the applicable tax rates, the status of indexation benefits, and how special categories like zero-coupon bonds and sovereign instruments are treated under Indian tax law.

Key Takeaways

Capital gains differ fundamentally from coupon interest — periodic coupon payouts are taxed under "Income from Other Sources" at your slab rate, whereas price appreciation upon transfer or sale triggers capital gains taxation.
Holding period thresholds depend on listing status — listed bonds require a holding period exceeding 12 months to qualify as Long-Term Capital Assets, whereas unlisted bonds require a holding period exceeding 24 months.
Long-Term Capital Gains (LTCG) on listed bonds are taxed at 12.5% — post-reform tax rules standardise LTCG on listed debt securities at a flat 12.5% without indexation benefits.
Short-Term Capital Gains (STCG) are taxed at marginal slab rates — gains on listed bonds held for 12 months or less, and unlisted bonds held for 24 months or less, are added to total taxable income and taxed at applicable slab rates.
Debentures historically do not carry indexation benefits — under the third proviso to Section 48 of the Income Tax Act, bonds and debentures (other than Capital Indexed Bonds and Sovereign Gold Bonds) have historically been excluded from indexation adjustments.
TDS rules apply to interest, not capital gains — while Tax Deducted at Source (TDS) applies to coupon payments on listed corporate debt, capital gains realised by resident individuals on secondary market sales generally do not face upfront TDS.
Certain special debt instruments carry distinct tax provisions — zero-coupon bonds, Market Linked Debentures (MLDs), and Section 54EC capital gains bonds each operate under dedicated sections of the Income Tax Act.

Understanding Capital Gains vs. Interest Income on Bonds

To compute your tax liability accurately, you must first separate the two distinct income streams that a bond holding can generate: Total Bond Returns = Periodic Coupon Payments + Capital Gains (or Losses)

1. Interest (Coupon) Income

When a bond issuer deposits periodic interest into your bank account—whether monthly, quarterly, semi-annually, or annually—that payment is categorised as "Income from Other Sources." This cash flow is added directly to your gross total income and taxed at your marginal income tax slab rate (plus applicable surcharge and cess). Our detailed guide on bond interest taxation in India outlines the specific TDS thresholds and reporting mechanisms for regular payouts.

2. Capital Gains

Capital gains arise only when a capital asset is transferred, sold, or redeemed at a value higher than its cost of acquisition. If you purchase a bond at a discount (or during a secondary market dip) and later execute an exit from the bond before maturity at a higher market price, that difference constitutes a capital gain.

Conversely, if market yields rise and you sell the bond at a discount to your acquisition cost, you incur a capital loss. Capital losses on bonds can be set off against other capital gains under the provisions of Section 70 and Section 74 of the Income Tax Act:

Short-term capital losses can be set off against both short-term and long-term capital gains.
Long-term capital losses can only be set off against long-term capital gains.
Unabsorbed capital losses can be carried forward for up to 8 assessment years, provided the tax return is filed within the statutory due date.

Listed vs Unlisted Bonds: Holding Periods and Tax Rates

The tax treatment of capital gains on debt instruments depends on two primary parameters: whether the security is listed on a recognised stock exchange in India, and the duration for which the asset was held prior to transfer.

Holding Period Classifications

The classification of a debt security as short-term or long-term depends on statutory thresholds under Section 2(42A) of the Income Tax Act:

Listed Bonds and Debentures: Held for 12 months or less = Short-Term Capital Asset; held for more than 12 months = Long-Term Capital Asset. This applies to listed corporate Non-Convertible Debentures (NCDs), Government Securities (G-Secs), State Development Loans (SDLs), and listed municipal bonds.
Unlisted Bonds and Debentures: Held for 24 months or less = Short-Term Capital Asset; held for more than 24 months = Long-Term Capital Asset.

Tax Rates Applied to Listed vs Unlisted Bonds

The table below summarizes the prevailing capital gains tax framework for resident individual investors:

Security Type	Holding Period for Long-Term	Short-Term Capital Gains (STCG) Rate	Long-Term Capital Gains (LTCG) Rate	Indexation Benefit Available?
Listed Corporate NCDs	> 12 Months	Marginal Tax Slab Rate	12.5%	No
Listed Government Securities (G-Secs)	> 12 Months	Marginal Tax Slab Rate	12.5%	No
Listed State Development Loans (SDLs)	> 12 Months	Marginal Tax Slab Rate	12.5%	No
Listed Zero-Coupon Bonds (Notified)	> 12 Months	Marginal Tax Slab Rate	12.5%	No
Unlisted Corporate Bonds / Debentures	> 24 Months	Marginal Tax Slab Rate	12.5%	No
Market Linked Debentures (Sec. 50AA)	Any Duration	Marginal Tax Slab Rate	Marginal Tax Slab Rate (Deemed STCG)	No

Note: All statutory rates are subject to applicable surcharge (based on income tier) and 4% Health and Education Cess.

Concrete Calculation Example: Listed Corporate Bond

To illustrate the mechanics of capital gains taxation, consider the following scenario for a retail investor:

Purchase Date: August 10, 2024
Security: 8.50% Listed Corporate NCD (Face Value: Rs. 1,000)
Purchase Price (Clean): Rs. 970 per bond
Quantity: 500 units (Total Investment: Rs. 4,85,000)
Sale Date: October 15, 2025 (Holding period = 14 months, 5 days)
Sale Price (Clean): Rs. 1,020 per bond (Total Consideration: Rs. 5,10,000)
Brokerage / Transaction Costs: Rs. 500 Gross Capital Gain = Total Sale Value - Cost of Acquisition - Transfer Expenses Gross Capital Gain = Rs. 5,10,000 - Rs. 4,85,000 - Rs. 500 = Rs. 24,500

Because the security is listed and was held for more than 12 months, the gain of Rs. 24,500 qualifies as Long-Term Capital Gain:

Applicable LTCG Tax Rate: 12.5%
Base Tax: 12.5% of Rs. 24,500 = Rs. 3,062.50
Health & Education Cess (4%): Rs. 122.50
Total Tax Payable on Capital Gain: Rs. 3,185.00

If this same investor had sold the bond on June 10, 2025 (after 10 months of holding), the Rs. 24,500 would be treated as Short-Term Capital Gain. For an investor in the 30% tax bracket (plus 4% cess, assuming no surcharge), the STCG tax would equal Rs. 7,644.00. The longer holding period reduces the tax incidence by more than half.

Investors seeking to structure their debt portfolios around multi-year liabilities often integrate holding period timelines into their broader tax planning for bond portfolios.

Recent Tax Reforms: What Changed for Fixed-Income Securities?

Taxation of debt instruments in India has undergone significant statutory revisions across recent Union Budgets. Understanding the context of these reforms prevents costly miscalculations on tax filings.

1. Rationalisation of Holding Periods

Previously, listed debt securities required a holding period of more than 12 months for long-term classification, while unlisted bonds required 36 months. The framework was simplified by aligning unlisted financial assets to a standardized 24-month threshold, while retaining the 12-month period for listed bonds.

2. Uniform 12.5% Long-Term Capital Gains Rate

The standard long-term capital gains tax rate for financial assets was harmonized at 12.5%. For listed bonds and debentures, the previous 10% rate without indexation was adjusted to 12.5%, creating uniformity across listed equities, listed debt, and other specified asset classes.

3. Confirmation of the Indexation Stance

Under Section 48 of the Income Tax Act, the third proviso explicitly denies the benefit of cost indexation to bonds and debentures, except in the case of Capital Indexed Bonds issued by the Government and Sovereign Gold Bonds issued by the RBI. The removal of indexation across other asset classes has made the treatment of bonds consistent with general capital gains principles across the tax code.

4. Section 50AA and Market Linked Debentures (MLDs)

Introduced to address regulatory arbitrage, Section 50AA mandates that any capital gains arising from the transfer, redemption, or maturity of a "Market Linked Debenture" or specified debt-oriented instruments (where debt allocation exceeds 65%) are deemed short-term capital gains. Regardless of whether an MLD is listed or held for five years, gains are taxed at the investor's applicable slab rate.

Special Categories: Zero-Coupon, Sovereign, and 54EC Bonds

Different bond structures carry unique statutory exceptions under the Income Tax Act. ┌───────────────────────────────┐ │ Special Bond Categories │ └──────────────┬────────────────┘ │ ┌─────────────────────────┼─────────────────────────┐ │ │ │ ┌────────▼────────┐ ┌────────▼────────┐ ┌────────▼────────┐ │ Zero-Coupon │ │ Sovereign Gold │ │ Section 54EC │ │ Bonds (ZCBs) │ │ Bonds (SGBs) │ │ Gains Bonds │ └────────┬────────┘ └────────┬────────┘ └────────┬────────┘ │ │ │ • Deep-discount • Capital gains on • Reinvestment of structure RBI redemption are real estate gains • 12m holding for fully exempt • 5-year lock-in listed notified ZCB • Secondary sale: • Interest taxable • 12.5% LTCG 12.5% if >12m at slab rate

Zero-Coupon Bonds (ZCBs)

Zero-coupon bonds do not pay periodic interest. Instead, they are issued at a deep discount to their face value and redeemed at par upon maturity.

For income tax purposes, notified zero-coupon bonds issued by infrastructure capital companies or public sector enterprises receive specific treatment under Section 2(48):

If the notified ZCB is held for more than 12 months, the difference between the redemption price and the issue price is taxed as Long-Term Capital Gain at 12.5%.
If held for 12 months or less, the gain is treated as Short-Term Capital Gain and taxed at marginal slab rates.

For a comprehensive evaluation of deep-discount structures, refer to our guide on zero-coupon bonds.

Sovereign Gold Bonds (SGBs)

Sovereign Gold Bonds carry distinct capital gains rules under Section 47(viic) of the Income Tax Act:

Redemption through RBI: Capital gains arising upon redemption with the RBI at the end of the 8-year tenure (or during early redemption windows after year 5) are 100% tax-exempt for resident individuals.
Secondary Market Sale: If an investor sells an SGB on a stock exchange before maturity, capital gains provisions apply. Held for over 12 months, gains are taxed as LTCG at 12.5% without indexation; held for 12 months or less, gains are taxed at slab rates.

Explore our guide on Sovereign Gold Bonds for details on secondary market yields and holding mechanisms.

Section 54EC Capital Gains Bonds

Section 54EC bonds (issued by REC, PFC, NHAI, or IRFC) are not bought to generate capital gains; rather, they are structured to offset capital gains arising from the sale of long-term real estate assets (land or building).

Investment Limit: Up to Rs. 50 lakh per financial year.
Lock-in Period: 5 years (non-transferable and non-negotiable).
Tax on Principal: Capital gains reinvested under Section 54EC within 6 months of property transfer are exempt from capital gains tax.
Tax on Interest: The annual interest received on 54EC bonds is fully taxable at your applicable marginal slab rate.

For eligibility criteria and structural parameters, see our Section 54EC capital gains bonds guide.

How Listed and Unlisted Bonds Compare for Tax Efficiency

When selecting between listed and unlisted fixed-income instruments, tax treatment is a central differentiator. The table below outlines how these two categories compare across practical investment metrics:

Parameter	Listed Debt Securities	Unlisted Debt Securities
Typical Instruments	Exchange-traded NCDs, G-Secs, SDLs	Private placements, unlisted NBFC paper
LTCG Holding Period	> 12 Months	> 24 Months
STCG Holding Period	≤ 12 Months	≤ 24 Months
LTCG Tax Rate	12.5% (plus cess/surcharge)	12.5% (plus cess/surcharge)*
STCG Tax Rate	Slab Rate	Slab Rate
TDS on Secondary Sale	No TDS for resident individuals	No TDS for resident individuals
TDS on Coupon Interest	10% under Section 193 (exempt for G-Secs)	10% under Section 194A
Secondary Market Exit	Readily executable on exchange order books	Bilateral or held strictly to maturity

*Note: Debt securities covered under Section 50AA are deemed short-term capital assets regardless of holding duration.

High-bracket investors frequently note the structural difference in holding periods. A listed bond transitions into the lower 12.5% LTCG bracket after just one year, whereas an unlisted instrument requires two full years to achieve the same classification.

Common Mistakes Bond Investors Make Regarding Capital Gains Tax

Fixed-income taxation contains nuances that can lead to errors on annual tax returns. Here are four common oversights:

Treating Dirty Price Realisation as Pure Capital Gains: When you sell a bond between coupon dates, the total consideration received (dirty price) includes accrued interest. Failing to split accrued interest from pure capital appreciation can lead to misreporting income headers. The accrued interest portion up to the settlement date represents interest income, while the clean price difference represents capital gains.
Assuming Debentures Qualify for Indexation: Many investors assume that because debt mutual funds historically received indexation (prior to April 2023), direct corporate debentures also did. Direct debentures and bonds have long been excluded from indexation under the third proviso to Section 48. Calculating indexed cost of acquisition for debentures is an error that invites tax notices.
Overlooking Section 50AA on Market Linked Debentures: Selling or redeeming an MLD after 3 years does not qualify for the 12.5% LTCG rate. Section 50AA explicitly treats all gains from MLDs as short-term capital gains taxable at your marginal slab rate.
Failing to Report Capital Losses: If a bond is sold at a discount due to rising market yields or credit spread widening, investors often omit reporting the loss because no tax is due. However, failing to file and report capital losses within the statutory deadline forfeits the ability to set off or carry forward those losses against future capital gains.

Frequently Asked Questions

Is capital gains tax applicable if I hold a corporate bond until maturity?

If you subscribed to a bond at face value (for example, Rs. 1,000) and the issuer redeems it at face value (Rs. 1,000) upon maturity, no capital gain or loss arises because the transfer consideration equals the cost of acquisition. However, if you purchased the bond at a discount in the secondary market (say, Rs. 950) and it is redeemed at par (Rs. 1,000), the Rs. 50 difference represents a capital gain realised on redemption and is taxable based on your holding period and the listing status of the bond.

How is accrued interest separated from capital gains when selling on the secondary market?

When an exchange-traded bond is sold, the buyer pays the dirty price (clean price plus accrued coupon interest from the last payment date). For income tax reporting, the accrued interest portion received is classified as "Income from Other Sources" and taxed at your marginal slab rate. The difference between the clean selling price and your original purchase price is reported under the "Capital Gains" schedule of your income tax return.

Do listed Government Securities (G-Secs) qualify for the 12.5% LTCG rate?

Yes. Listed Government Securities and State Development Loans (SDLs) are debt securities traded on recognized stock exchanges. When held for more than 12 months by resident individual investors, capital gains realised upon sale in the secondary market are categorized as long-term capital gains and taxed at the rate of 12.5% (plus applicable surcharge and cess) without indexation.

What is the TDS rate on capital gains from bond sales for resident individuals?

There is no Tax Deducted at Source (TDS) on capital gains realised by resident individual investors selling bonds on domestic secondary market exchanges or online bond platforms. You are responsible for calculating the capital gains, including them in your advance tax computations, and paying the tax directly. Note that TDS does apply to periodic coupon interest payments under Section 193 of the Income Tax Act.

Can long-term capital losses from listed bonds offset gains from equity shares?

Yes. Under Section 70 and Section 74 of the Income Tax Act, long-term capital losses arising from the sale of listed bonds can be set off against long-term capital gains from any other capital asset, including listed equities, equity mutual funds, and real estate. However, long-term capital losses cannot be set off against short-term capital gains or regular salary/business income.

Bottom Line

Understanding the capital gains tax rules on Indian bonds allows fixed-income investors to calculate net post-tax yields accurately. Listed bonds offer a distinct structural timeline, qualifying for a 12.5% Long-Term Capital Gains tax rate after a 12-month holding period. In contrast, unlisted bonds require a 24-month holding period to achieve long-term classification, while Market Linked Debentures remain taxable at marginal slab rates regardless of tenure.

By distinguishing periodic coupon income from capital appreciation, tracking statutory holding periods, and separating clean prices from accrued interest, you can evaluate fixed-income opportunities with clear expectations of net returns.
