Taxation of Debt Products for NISM Series X-B

Taxation of debt products asks how each return is taxed: interest, discount, capital gains or dividend. For each instrument, identify the type of income, the holding period, and whether the instrument is listed. Then apply the right rate or exemption. Check the workbook's current version, because rates and thresholds change.

What this chapter covers

This chapter covers how returns from debt instruments are taxed in the hands of an investor. It starts with coupon interest on bonds and debentures, then moves to capital gains on selling them. It then covers debt mutual funds, discount instruments such as zero coupon bonds and T-bills, special instruments such as tax-free bonds and Sovereign Gold Bonds, and finally accrued interest and bond stripping.

The central skill is classification. The same ₹1,00,000 of return can be interest, capital gains, or a deemed short-term gain, and each is taxed differently. Ask three questions every time: what is the nature of the income, what is the holding period, and is the instrument listed or unlisted?

This chapter links directly to the rest of the X-B paper. Post-tax return is what you compare when recommending a debt fund, a tax-free bond or a bank deposit, and the same logic runs through portfolio construction and caselets. Tax rules change often, so learn the logic and then confirm the figures against the current NISM workbook.

X-B tests whether you can advise a client on post-tax outcomes, not just pre-tax returns. Questions in this chapter are rule-based and usually have one clear answer, so you can score reliably if your classification is sound. They also appear inside caselets, where one wrong tax treatment can cost several linked questions. With negative marking of 25% of the marks assigned to a question, guessing on these rule-based questions is expensive.

Taxation of Debt Products: topics in the order to study them

  1. 1Taxation of Interest on Bonds and DebenturesInterest is the base case. It is taxed as income at the investor's slab rate, and every later topic is a variation on it.
  2. 2Capital Gains on Bonds and DebenturesOnce you know interest, you separate it from the gain or loss on sale. Here you learn holding periods and the listed versus unlisted split.
  3. 3Taxation of Debt Mutual FundsThis applies the capital gains logic to units. Learn the rule for specified mutual funds, the acquisition date cut-offs, and dividend taxation.
  4. 4Taxation of Zero Coupon Bonds, Deep Discount Bonds and T-BillsThese have no periodic interest, so you must work out what counts as interest and what counts as a capital gain.
  5. 5Tax-Free Bonds, Sovereign Gold Bonds and Other Debt InstrumentsThese are exceptions to the general rules. Learn them after the rules so the exemptions stand out and you know what is exempt and what is not.
  6. 6Bond Stripping, Accrued Interest and Cum/Ex-Interest TransactionsThis is the most technical topic. It needs a clear idea of interest and gains from the earlier topics.

How to prepare Taxation of Debt Products

Build one comparison sheet for the whole chapter and fill it as you study, rather than memorising each topic in isolation.

  1. Make a table in your notes with a row for each instrument: bond, debenture, debt fund, zero coupon bond, T-bill, tax-free bond, SGB. Add columns for income type, holding period, rate and exemption.
  2. Learn the holding period test first. Note which instruments are treated as long-term after a set period and which are taxed at slab rate whatever the period.
  3. Write down the effective date for each rule, such as acquisition or transfer dates. Examiners use these dates to create trap options.
  4. Work through at least three numerical examples per topic: a coupon bond sold at a gain, a debt fund redeemed, and a purchase with accrued interest. Recompute each by hand.
  5. For each exemption, note exactly what is exempt and what is still taxable. For example, tax-free bond interest is exempt but capital gains on sale are not.
  6. Practise timed MCQs and caselets. Review every wrong answer and tag it as a classification error, a date error or an arithmetic error.
  7. Before the exam, check the current workbook for any change in rates, thresholds or definitions, and update your sheet.

Common mistakes in Taxation of Debt Products

  • Treating all debt mutual fund gains as long-term after a holding period

    Fix: Check the fund type first. From AY 2026-27 (FY 2025-26), gains on units of specified mutual funds (section 50AA), meaning funds investing more than 65% in debt and money market instruments, are deemed short-term and taxed at slab rate regardless of holding period. The earlier version covered units acquired on or after 1 April 2023 in funds investing not more than 35% in equity. Units acquired before 1 April 2023 were outside that earlier version.

  • Applying the 12-month long-term test to unlisted bonds and debentures

    Fix: Split listed and unlisted. Where an unlisted bond or debenture is transferred, redeemed or matures on or after 23 July 2024, the gain is a deemed short-term capital gain taxed at slab rate. Bonds issued by the Government or under a notified scheme are outside this rule. The 12-month test applies to listed bonds.

  • Including accrued interest in the cost or sale price of a bond

    Fix: Separate the clean price from accrued interest. Treat accrued interest as interest and only the price difference as capital gain.

  • Assuming tax-free bonds are tax-free on every return

    Fix: Remember the exemption covers only the interest. A gain from selling above cost is a capital gain and is taxable.

  • Treating Sovereign Gold Bond returns as wholly exempt or wholly taxable

    Fix: Split the return. Interest is taxable. Capital gains on redemption by an individual are exempt, including premature redemption through the RBI after the fifth year. Gains on an exchange sale or a transfer to another person are taxable.

  • Using outdated rates and thresholds

    Fix: Learn the logic from your notes but verify every rate, period and date against the current NISM workbook.

Last-day revision: Taxation of Debt Products

  • Interest on bonds and debentures is taxed at the investor's slab rate as income from other sources.
  • Interest and capital gains are separate. Always split the sale proceeds into accrued interest and price gain.
  • For transfers on or after 23 July 2024, long-term gains on listed bonds and debentures (held more than 12 months) are taxed at 12.5% without indexation. Earlier transfers followed the older rate, so check the transfer date.
  • Unlisted bonds and debentures give a deemed short-term capital gain under section 50AA, taxed at slab rate whatever the holding period. The gain can arise on transfer, redemption or maturity on or after 23 July 2024. This is a deemed capital gain rule, not an interest rule. It does not cover bonds issued by the Government or under a notified scheme.
  • From AY 2026-27 (FY 2025-26), section 50AA applies to units of specified mutual funds, meaning funds that invest more than 65% in debt and money market instruments. Gains on these units are deemed short-term and taxed at slab rate whatever the holding period. The earlier version of the rule covered units acquired on or after 1 April 2023 in funds investing not more than 35% in equity. Units acquired before 1 April 2023 were outside that earlier version, so confirm their treatment in the current workbook.
  • Dividends from mutual funds are taxed at slab rate in the investor's hands.
  • Tax-free bond interest is exempt, but capital gains on selling the bond are taxable.
  • SGB interest of 2.5% a year is taxable. Capital gains on redemption of an SGB by an individual are exempt, including premature redemption through the RBI after the fifth year. A sale on an exchange or a transfer to another person is taxable as capital gains. Long-term gains on a listed SGB held more than 12 months are taxed at 12.5%.
  • A buyer in a cum-interest trade pays accrued interest to the seller. Accrued interest is not part of the cost of the bond. The seller treats the accrued interest received as interest income, and the clean price decides the seller's capital gain. The buyer deducts the accrued interest paid from the interest income the buyer later receives.
  • Zero coupon and discount instruments have no coupon, so identify whether the return is treated as interest or capital gain.
  • Confirm all rates and thresholds against the current workbook before the exam.

Taxation of Debt Products: frequently asked questions

How is interest on bonds and debentures taxed?

For an individual investor it is added to total income and taxed at the slab rate. It is separate from any capital gain on selling the bond.

How are debt mutual funds taxed now?

From AY 2026-27 (FY 2025-26), section 50AA applies to units of specified mutual funds, meaning funds that invest more than 65% in debt and money market instruments. Gains on these units are deemed short-term and taxed at slab rate. The earlier version covered units acquired on or after 1 April 2023 in funds investing not more than 35% in equity, and units acquired before 1 April 2023 were outside that earlier version.

Is the interest on tax-free bonds taxable?

No, interest on tax-free bonds is exempt for the investor. A capital gain on selling the bond in the market is still taxable, and the holding period decides whether it is short-term or long-term.

Are Sovereign Gold Bonds tax-free?

Only partly. The 2.5% annual interest is taxable. Capital gains on redemption by an individual are exempt, including premature redemption through the RBI after the fifth year. A sale on the exchange or a transfer to another person is taxed as a capital gain, and a long-term gain on a listed SGB held more than 12 months is taxed at 12.5%.

Why should I learn accrued interest for the tax chapter?

Because tax treatment depends on splitting the price paid between accrued interest and the bond's cost. A single mistake there changes both the interest income and the capital gain in a caselet.
