Debenture-to-Share Conversion and Interest Taxability: Key Lessons from the Madras High Court Ruling

Introduction: The Central Question

When a debenture holder converts their instrument into equity shares without receiving a single rupee in cash, can the interest component embedded in that conversion be brought to tax? At first glance, an assessee following the cash system of accounting might confidently answer "no." However, a closer reading of the Madras High Court's recent ruling reveals that the answer is far more nuanced — and turns entirely on what the conversion consideration actually represents.

The core issue is not merely whether cash changed hands. The real inquiry is whether an accrued interest entitlement was discharged through the allotment of shares. If it was, the absence of cash does not shield that interest from taxation.

The Madras High Court Ruling: Facts at a Glance

Sanjjay Saumyha v. Principal Commissioner of Income-tax

In this case, the assessee held debentures with an original value of approximately ₹1 crore. Upon conversion, equity shares valued at approximately ₹1.75 crore were allotted to her. The difference was not arbitrary — the conversion value expressly included accumulated interest of ₹75.46 lakh.

The assessee's defence rested on the cash method of accounting: since no interest had been received in cash, she argued that no taxable interest arose in the relevant year. The Assessing Officer initially accepted the return without bringing the interest component to tax.

However, the Principal Commissioner of Income-tax exercised revisionary jurisdiction under Section 263, holding that the Assessing Officer's acceptance of the return on this point was erroneous and prejudicial to the interests of Revenue. The Tribunal upheld the revision.

The Tribunal decision is reported as Sanjjay Saumyha (Mrs.) v. PCIT, [2025] 210 ITD 337 (Chennai); the High Court ruling is reported as TS-1517-HC-2026(MAD).

The Madras High Court subsequently affirmed the Revenue's position. The decisive factor was that the ₹75.46 lakh interest component had been separately identified in the conversion value and was effectively extinguished through the share allotment. The interest obligation did not merely remain outstanding — it was treated as settled on the date of conversion.

Why Cash-Basis Accounting Does Not Automatically Protect the Assessee

The Nature of "Receipt" Under Income Tax Law

The cash method of accounting defers taxation until income is actually received. This is well-established. But what constitutes "receipt" under the Income Tax Act, 1961 is broader than the physical collection of currency notes.

Two distinct concepts deserve attention here:

1. Constructive Receipt
This refers to an amount that has been made available to an assessee — placed at their disposal — even though physical payment has not occurred. The classic example is a cheque deposited in a bank but not yet encashed.

2. Receipt in Kind
This refers to an asset actually delivered to the assessee in satisfaction of an entitlement. Here, the assessee receives something of value — not cash, but something equivalent to or representative of cash.

The conversion in Sanjjay Saumyha is more accurately analysed through the lens of receipt in kind rather than constructive receipt. The company allotted shares, and those shares discharged an expressly quantified interest liability. The interest obligation was not left hanging — it was considered settled. The form of settlement (shares rather than cash) does not alter the character of what was received.
