Taxation of Market Linked Debentures
Market Linked Debentures (MLDs) are debt securities whose returns are tied to the performance of a market index or a basket of equities. This sub‑topic explains how the interest component and the capital gains component of MLDs are taxed under Indian law. Understanding the tax treatment helps advisers give correct advice and avoid common exam pitfalls.
Learning Objectives

- 4Explain TDS, reporting requirements and exam‑relevant calculations.
What are Market Linked Debentures?
Market Linked Debentures (MLDs) are unsecured debt instruments issued by banks or NBFCs where the coupon or redemption amount is linked to the performance of a predefined market index, such as Nifty 50 or Sensex.
Unlike conventional debentures that pay a fixed interest, MLDs offer a variable return: a guaranteed minimum coupon (often zero) and an additional payoff that depends on the index’s appreciation over the holding period.
For the NISM exam, it is essential to recognise that MLDs are treated as debt securities for tax purposes, but the contingent payoff creates a capital gains element that must be taxed separately.
- Guarantee – Most MLDs guarantee the return of the principal at maturity.
- Contingent Payoff – The excess return above the guaranteed coupon is linked to market performance.
Tax Components in MLDs
When an investor holds an MLD, two distinct cash‑flows can arise: the periodic interest (or coupon) that is paid during the tenure, and the redemption amount received at maturity.
The periodic interest is taxed as interest income under the Income Tax Act. The redemption amount may contain a capital component – the difference between the redemption price and the original cost – which is subject to capital gains tax.
Exam candidates often overlook that the entire redemption proceeds are not automatically classified as interest. The split between interest and capital gain must be identified to apply the correct tax rate.
Students frequently treat the whole redemption amount of an MLD as interest income. Remember: only the coupon portion is interest; any excess over the cost price is capital gain and taxed accordingly.
Interest Income Taxation
The periodic interest (or guaranteed coupon) earned on an MLD is taxed as "Income from Other Sources". For individual investors, it is added to total income and taxed at the applicable slab rates.
Tax Deducted at Source (TDS) at 10% is applicable if the interest exceeds ₹10,000 in a financial year, provided the PAN is furnished. If PAN is not furnished, TDS is levied at the higher rate of 20%.
Advisers should remind clients to claim the interest in the appropriate schedule of the ITR and to retain the interest certificate issued by the issuer for audit purposes.
Capital Gains Taxation
The capital component arises when the redemption amount exceeds the purchase price. The tax treatment depends on the holding period of the MLD, which follows the rules for debt instruments.
If the MLD is held for 36 months or less, the gain is classified as Short‑Term Capital Gain (STCG) and taxed at the investor’s slab rate, just like interest income.
If the holding period exceeds 36 months, the gain is a Long‑Term Capital Gain (LTCG) and is taxed at a flat 20% rate with indexation benefit. Indexation allows the cost of acquisition to be adjusted for inflation using the Cost Inflation Index (CII) published by the government.
Where:
CG= Capital gain amount in rupeesSP= Sale/Redemption consideration in rupeesCP= Cost of acquisition in rupeesIA= Indexation allowance = CP \times \frac{CII_{sale}}{CII_{purchase}}Worked Example
Given: CP = 100,000 rupees, Purchase CII = 280, Sale CII = 340, SP = 130,000 rupees. Step 1: IA = 100,000 \times (340 / 280) = 121,428.57 rupees. Step 2: CG = 130,000 - (100,000 + 121,428.57) = -91,428.57 rupees (negative, i.e., no LTCG). Verification: 130,000 - (100,000 + 121,428.57) = -91,428.57.
Tax Treatment of MLD Components based on Holding Period
| Component | Holding Period | Tax Rate | Indexation |
|---|---|---|---|
| Interest (Coupon) | Any | Slab rates (individual) or 30% (company) | N/A |
| Short‑Term Capital Gain | ≤ 36 months | Slab rates | N/A |
| Long‑Term Capital Gain | > 36 months | 20% (plus surcharge & cess) | Allowed |
Remember the 36‑month rule for debt‑linked instruments. Any gain realised within 36 months is taxed at slab rates; beyond that, a flat 20% with indexation applies.
Tax Deducted at Source (TDS) on MLDs
TDS on the interest component of an MLD is deducted at 10% when the total interest in a FY exceeds ₹10,000 and the investor’s PAN is available. If PAN is not furnished, the rate rises to 20%.
There is no TDS on the capital gains component because gains are realised only at redemption, which occurs after the financial year ends.
Advisers should ensure clients receive Form 16A (or its electronic equivalent) for the interest TDS and claim the credit while filing returns.
Reporting MLDs in Income Tax Return
All interest earned from MLDs must be disclosed under "Income from Other Sources" (Schedule OS). The capital gains—both short‑term and long‑term—are reported in Schedule CG.
For LTCG, the indexation benefit is claimed by providing the Cost Inflation Index for the purchase and sale years. The net LTCG after indexation is then multiplied by 20% to compute tax.
Failure to report either component correctly is a common cause of assessment notices, and the NISM exam often asks for the correct schedule name.
Tax Payable on Sample MLD (₹100,000 investment)
Scenario
Ramesh buys an MLD on 1‑Apr‑2020 for ₹100,000. The guaranteed coupon is 0%. The index rises 30% over 5 years, and the issuer redeems the MLD at ₹130,000 on 31‑Mar‑2025. Compute the tax liability.
Solution
Step 1: Identify components – No coupon, so interest = ₹0. Step 2: Compute capital gain = Redemption – Cost = 130,000 – 100,000 = ₹30,000. Step 3: Holding period = 5 years (>36 months) → LTCG. Step 4: Apply indexation: CII for 2020‑21 = 301, for 2024‑25 = 348. IA = 100,000 × (348/301) = 115,614.62. Adjusted cost = 100,000 + 115,614.62 = 215,614.62. Step 5: LTCG = 130,000 – 215,614.62 = –85,614.62 (negative), so no LTCG tax. Step 6: Since there is no interest, total tax payable = ₹0.
Conclusion
Ramesh incurs no tax because the indexed cost exceeds the redemption amount, illustrating the benefit of indexation on long‑term gains.
Impact of Underlying Index Performance
The contingent payoff of an MLD is directly tied to the percentage change in the underlying index. A higher index rise increases the redemption amount, potentially creating a larger capital gain.
Conversely, if the index falls, the redemption may be limited to the guaranteed principal, resulting in zero or minimal capital gain. In such cases, only the interest (if any) is taxable.
Exam questions may present two scenarios – one with a bullish index and another with a bearish index – to test whether you can correctly classify the resulting tax treatment.
Key Differences between MLDs and Traditional Debentures
Comparison of MLDs vs Traditional Fixed‑Rate Debentures
| Feature | Market Linked Debenture | Traditional Debenture |
|---|---|---|
| Return Structure | Variable – linked to market index | Fixed coupon rate |
| Tax on Coupon | Interest income – slab rates | Interest income – slab rates |
| Capital Component | Possible LTCG/STCG on redemption | Usually no capital gain (redeemed at par) |
| Risk Profile | Higher market risk | Lower credit risk, no market exposure |
Indexation benefit is available only for long‑term capital gains on debt‑linked instruments like MLDs. It does not apply to the interest component.
⭐Exam Takeaways
- Market Linked Debentures are debt securities whose payoff is tied to a market index, creating both interest and capital gain components.
- Interest (coupon) is taxed as ordinary income at the investor’s slab rate; TDS of 10% applies if interest > ₹10,000 and PAN is furnished.
- Capital gains are taxed based on holding period: ≤36 months = STCG (slab rates), >36 months = LTCG at 20% with indexation.
- Indexation allowance = Cost of acquisition × (CII of sale year ÷ CII of purchase year) and is used only for LTCG on debt‑linked instruments.
- Report interest under Schedule OS and capital gains under Schedule CG in the ITR; provide CII details for LTCG calculations.
- No TDS is deducted on the capital gains component; tax is payable at the time of filing the return.
- For exam questions, always separate the coupon from the redemption amount before applying tax rates.
- Remember the 36‑month rule and that indexation benefits apply only to long‑term capital gains, not to interest.
