Zero Coupon Bond (ZCB)

What Is a Zero Coupon Bond?

A zero coupon bond (ZCB) is a bond that does not pay regular interest, also called a coupon. Instead, it is generally bought below its face value—the amount the issuer promises to pay at maturity. The difference between the purchase price and the amount received is the investor’s return before tax and costs. For Indian tax purposes, however, a bond must satisfy the applicable statutory conditions and notification requirements to qualify as a “zero coupon bond.”

For example, suppose an NRI buys a bond for ₹80,000 and receives its face value of ₹1,00,000 at maturity. The difference is ₹20,000. Unlike a conventional bond, there are no scheduled interest payments while the investor holds it.

How Does a Zero Coupon Bond Work?

A ZCB can suit someone planning for a future lump-sum expense rather than regular income. However, the maturity amount is a promise by the issuer, not a risk-free guarantee. If the issuer cannot repay, the investor could lose money. Selling before maturity may also produce a different return because the bond’s market price can change.

For NRIs, another practical consideration is timing: the money remains tied to a future payment date unless the bond can be sold earlier. Check whether an active market exists before assuming you can exit when needed, and confirm that the particular bond is eligible for NRI investment under applicable FEMA/RBI rules.

How Is a ZCB Taxed in India?

Indian tax law has a specific definition of a zero coupon bond. A bond does not automatically receive that tax treatment simply because it makes no regular interest payments. The qualifying conditions include requirements concerning the issuer, payments before maturity, and government notification.

For a bond that qualifies under that definition, maturity or redemption is treated as a transfer for capital-gains purposes. A zero coupon bond is generally treated as a short-term capital asset if held for not more than 12 months; for transfers on or after 23 July 2024, long-term capital gains on a qualifying zero coupon bond are generally taxed at 12.5% without indexation, subject to the applicable rules. An NRI should check the issue documents and tax classification before reporting the return. The country where the NRI lives may have its own tax or reporting requirements.

What Should an NRI Check?

Before investing, confirm the issuer’s creditworthiness, purchase price, maturity value, maturity date, and options for selling early. Ask whether the particular bond issue qualifies as a notified zero coupon bond for Indian tax purposes. Keep the allotment and redemption records to support the tax calculation.

In short: A ZCB exchanges regular interest payments for a potential lump-sum return at maturity. Its actual return depends on the price paid, repayment by the issuer, and tax treatment.
