Zero-Coupon Bond Taxation In India: Rules, Rates, And Investor Guide (2026)
With a Compound Annual Growth Rate (CAGR) of 25%, the Indian bond market showed exponential growth in the last decade1. In 2024, bonds worth INR 9.5 lakh crore were issued. While there are different types of bonds, suiting distinct investor needs, a unique bond category is the Zero-Coupon Bond.
As the name suggests, unlike regular bonds, zero-coupon bonds do not carry any coupon rate or interest rate. The zero-coupon bond returns are the difference between the discount at which they are issued and the face value at which they are redeemed. Therefore, these bonds are suitable for long-term investors, looking for a lump-sum yield rather than regular payouts at intervals.
However, analysing the suitability of a zero-coupon bond investment by understanding its return requires considering the zero-coupon bond taxation. Therefore, this blog will help you decode the deep discount bond tax rules.
Zero-Coupon Bond Taxation In India
Exploring a few key concepts related to the zero-coupon bonds before moving on to the zero-coupon bond taxation is important to decode the tax laws optimally.
Let us first understand the meaning of zero-coupon bonds by comparing them with regular bonds.
1. Difference Between Regular And Zero Coupon Bonds
The table below compares zero-coupon bonds with regular bonds.
| Parameter | Zero-Coupon Bonds | Regular Bonds |
| Interest Payment | Interest is not paid on zero-coupon bonds. | It has an interest rate, called the coupon rate, which is payable at predetermined intervals. |
| Purchase Price | It is issued at a discount on the face value. | It is issued at the market price. |
| Income | Lump-sum repayment at maturity. | Regular interest payouts, along with principal repayment at maturity. |
| Example | If Mr A buys 10 zero-coupon bonds, which have a face value of INR 100, at a discount of 10%, his return is discussed below. Purchase Price = 10 x INR 90 = INR 900 Repayment after maturity = 10 x INR 100 = INR 1000 Return = INR 1000 - INR 900 = INR 100 | If Mr A buys 10 bonds with a face value of INR 100, his returns after a year are discussed below. Given that the Market Price was INR 110 and the interest is 6%. Purchase Price = 10 x INR 110 = INR 1,100 Interest = 6% x (10 x INR 100) = INR 60

Moreover, the categorisation of the zero-coupon bond returns is important to explore their taxability, as it determines the applicable tax rate.
2. Income Classification: Capital Gains Vs Interest Income
While capital gain refers to the income earned from the sale or liquidation of an asset, interest income refers to the periodic return payout. Now, in the light of this concept, let us explore how income from zero-coupon bonds can be categorised, to better understand income tax on bonds in India.
- No interest: Since zero-coupon bonds do not have regular interest payouts, the yield cannot be categorised as interest income.
- Payment timing: The return of zero-coupon bonds is not paid at periodic intervals but at maturity, post-liquidation of investment.
Therefore, returns from zero-coupon bonds are categorised as capital gains.
Let us now take a look at the capital gains tax on zero-coupon bonds.
Short-Term vs Long-Term Taxation Zero-Coupon Bonds
The taxability of an asset differs based on the period for which it is held. Zero-coupon bond taxation also differs based on tenure. Let us first explore the concept of zero-coupon bond holding period, then get into the relevant tax rates.
1. Zero-Coupon Bond Holding Period
Primarily, a capital gain can be categorised as a long-term capital gain or a short-term capital gain, depending on its holding period. The tenure often varies from one asset category to another. Let us analyse the holding period in relation to zero-coupon bonds.
| Particulars | Holding Period |
| Short term | Not more than 12 months |
| Long term | More than 12 months |
Now, let’s look at the zero-coupon bond taxation based on holding period.
Zero-coupon bonds can be issued by some specific organisations, notified by the government. Entities like NABARD (National Bank for Agriculture and Rural Development), REC Ltd., Indian Railway Finance Corporation Ltd., etc., are eligible to issue zero-coupon bonds as per the latest notifications. Discussed below are the applicable tax rates2.
| Holding Period | Transferred before 23 July 2024 | Transferred on or after 23 July 2024 |
| Long-Term Capital Gain | 20% with indexation benefits or 10% without indexation benefits. | 12.5% without indexation benefits. |
| Short-Term Capital Gain | Taxed as per applicable tax slabs. | Taxed as per applicable tax slabs. |
Now, let us zoom in on indexation benefits and other tax-saving methodologies.
Recent ZCB Issuances In India (2025–2026)
Last year, in 2025, a few government-backed financial institutions issued zero-coupon bonds to raise long-term funds cost-effectively. Here are some ZCB issuances in 2025, as follows
NABARD
NABARD is authorised to issue INR 19,500 crore worth of 10-year, 11 months and 13-day ZCBs. To support rural infrastructure and agricultural development. It offers long-term maturity and lower risk as they are backed by the government financial institution NABARD.
REC Limited
REC Limited has received clearance from CBDT to issue INR 5,000 crore in 10-year, 6-month ZCBs. It was issued to mobilise the power sector and support energy infrastructure projects across India.
Power Finance Corporation
PFC issued long-term 15-year public NCD ZCBs in March 2025 to finance India’s power generation and renewable energy projects. However, the proposed ZCB was later removed because of low demand from institutional investors.
HUDCO
The Housing and Urban Development Corporation (HUDCO) secured government approval to issue INR 5,000 crore in 10-year ZCBs to support urban infrastructure projects. These fund proceeds are used for housing and city development initiatives in India and were issued in April 2025.
Tax-Saving Strategies For Zero-Coupon Bond Investors
Discussed in this section are some tax-saving techniques that can aid in making key investment decisions.
Indexation Benefit Bonds
Union Budget 2024 removed indexation benefits from most capital gains. The indexation benefits applicable to zero-coupon bonds have also become restricted.
- Maturity before 23 July 2024: If the bond units mature before this due date, investors have the option of availing indexation benefits. If the indexation benefit is used, the applicable tax rate will be 20%. However, if it is not used, the applicable tax rate will be 10%.
- Maturity on or after 23 July 2024: If the bond units mature on or after this due date, no indexation benefit is levied.
Another method of tax-saving is to compare the zero-coupon bonds with other alternative investment avenues and choose the one that fits financial goals the most.

Benefits And Drawbacks of Zero-Coupon Bonds
Benefits of Zero-Coupon Bonds
1. Guaranteed payout at maturity
A major advantage of zero-coupon bonds is the certainty of returns. Since they don’t pay periodic interest, investors know exactly how much they will receive on maturity. This makes them ideal for long-term financial goals like retirement planning or children’s education.
2. Affordable entry point
Zero-coupon bonds are issued at a steep discount to their face value, allowing investors to start with a relatively small amount. This lower entry cost makes them accessible while still offering the potential for significant returns over time.
3. No reinvestment risk
Traditional bonds require investors to reinvest periodic interest payouts, often at uncertain rates. Zero-coupon bonds eliminate this reinvestment risk since there are no interim cash flows—the entire return is realized at maturity.
Drawbacks of Zero-Coupon Bonds
1. Tax implications
Even though investors don’t receive annual interest, the bond’s “imputed interest” (accrued income) is still taxable each year. This creates a situation of paying taxes on notional income, often referred to as phantom income.
2. Long lock-in periods
Most zero-coupon bonds come with extended maturities ranging from 10 to 30 years. This long holding period reduces liquidity and may not suit investors who might need access to funds earlier.
3. High sensitivity to interest rates
Zero-coupon bonds are more vulnerable to changes in market interest rates. A rise in interest rates can push down their secondary market value, leading to potential losses if investors decide to sell before maturity.
Risks In Zero-Coupon Bonds
Investors should know the risks involved in ZBCs before investing. The bonds might offer predictable maturity proceeds but involve some risks.
- Interest Rate Risk - Since there are no periodic coupon payments in ZCBs. Their price fluctuates more than regular bonds when interest rates change. The market value of these bonds decreases with rising interest rates.
- Credit Risk - During any financial difficulties faced by issuers, the repayment may be delayed or, sometimes, default. Investors should check the issuer’s credit rating before investing.
- Liquidity Risk - Some deep discount bonds may not be actively traded in the secondary market, which makes early exit difficult.
- Inflation Risk - Although the maturity value is fixed in ZCBs, inflation can reduce the real purchasing power of returns over time.
- Opportunity Cost - As money remains locked for several years without generating any periodic income. Investors can miss other investment opportunities offering higher returns due to this.
Conclusion
While choosing the best investment medium that fits your financial goals and investment philosophy, analysing the taxability is a key consideration as well. Taxes diminish the real returns that investors get. Therefore, analysing them shows the real expected return.
