Interest on Securities under the Income-tax Act, 1961

Introduction

Interest income from securities is a significant component of non-salary income in India and is governed by a well-defined legal framework under the Income-tax Act, 1961. The term “interest on securities” is defined under Section 2(28B) of the Act and broadly covers interest on Central and State Government securities, as well as interest on debentures or similar instruments issued by local authorities, companies, or statutory corporations. The taxation of such income involves careful classification, procedural application, and anti-avoidance safeguards.

Depending on the status and intent of the holder, interest income may be taxed under different heads. For instance, if securities are held as stock-in-trade, the interest is assessed under the head “Profits and Gains of Business or Profession.” In other cases, particularly where the securities are held as long-term investments, interest is chargeable under the head “Income from Other Sources” as per Section 56(2)(id). This classification plays a crucial role in determining the availability of deductions and the applicable computation method.

The method of accounting followed by the assessee determines whether the interest is taxable on an accrual basis or a receipt basis. However, when no specific accounting method is adopted, interest is always taxed on a due basis. Another key principle is that interest on securities does not accrue on a daily basis. It becomes taxable only on the due date declared by the issuing authority, irrespective of how long the securities were held during the year. In such cases, the entire interest is taxable in the hands of the person holding the security on the due date.

The Income-tax Act also includes provisions to deal with potential tax avoidance in relation to interest on securities. Section 94 addresses transactions such as bond washing, wherein taxpayers may try to shift income to individuals in lower tax brackets by transferring securities just before interest payment dates and re-acquiring them afterward. To prevent such evasion, the Act deems the interest income to be taxable in the hands of the original holder.

This paper provides a detailed overview of the tax treatment of interest on securities, including grossing-up of net interest, allowable deductions, anti-avoidance provisions, and treatment of Deep Discount Bonds. A close study of this area is critical for professionals, students, and taxpayers alike, given its frequent application in investment taxation and compliance.

Meaning of Interest on Securities [Section 2(28B)]

As per Section 2(28B) of the Income-tax Act, 1961, “interest on securities” includes:

1. Interest on any security issued by the Central Government or State Government.
2. Interest on debentures or other securities issued by or on behalf of:
   • a local authority;
   • a company;
   • a corporation established by or under a Central, State or Provincial Act.

This definition is inclusive and encompasses both government-backed and private sector instruments.

Taxability Depending on Holding Status

The head under which interest income is taxed depends upon the manner in which the securities are held:

1. If securities are held as stock-in-trade by a business entity, the interest income is taxed under the head “Profits and Gains of Business or Profession.”
2. If the securities are held otherwise than as stock-in-trade, the interest is taxed under “Income from Other Sources” as per Section 56(2)(id).

This distinction is essential because it determines the kind of deductions that can be claimed and the compliance requirements applicable to the assessee.

Basis of Chargeability

The interest on securities may be taxed on either a due basis or a receipt basis, depending on the accounting method regularly followed by the assessee. If the assessee follows the mercantile system, income is taxable on a due basis. If the cash system is followed, taxability arises upon actual receipt. In the absence of any specific method, interest is taxed on a due basis.

It is important to note that interest on securities does not accrue daily. Instead, it becomes due on specific dates as declared by the issuer. The person holding the security on such due date is liable to pay tax on the entire interest amount, irrespective of the duration for which they held the security during the year.

Grossing-up of Interest

In cases where interest is received net of tax, i.e., after deduction of tax at source (TDS), the gross amount must be calculated to ascertain the actual income. The formula for grossing up is:

Gross Interest = (Interest Received × 100) ÷ (100 – TDS rate)

For example, if an investor receives ₹9,000 after TDS of 10 percent, the gross income is calculated as ₹9,000 × 100 ÷ 90 = ₹10,000. This gross amount is taxable, and credit for TDS can be claimed against tax liability.

Deductions from Interest Income 

As per Section 57 of the Income-tax Act, the following deductions are allowed from interest income under the head “Income from Other Sources”:

a) Commission or remuneration paid for realisation of interest.
b) Interest on loan taken for investment in such securities.
c) Any other expenditure incurred wholly and exclusively for earning such income.

However, expenses of a personal nature or those disallowed under Section 58 are not permitted as deductions.

Anti-Avoidance Provisions 

Section 94 of the Act addresses attempts to avoid tax through certain transactions in securities:

1. Section 94(1) deals with bond washing transactions. If securities are transferred before the interest due date and re-acquired afterward, interest is taxed in the hands of the original transferor, not the transferee.
2. Section 94(2) applies if a transaction results in reduced or no income to the person who has beneficial interest in the security. In such cases, the actual income from the securities is still taxed in the hands of that person.
3. Section 94(3) provides exceptions if the assessee can prove that the transaction was not part of a systematic tax avoidance scheme.
4. Section 94(6) empowers the Assessing Officer to call for information regarding such securities and transactions.

Taxation of Deep Discount Bonds

Deep Discount Bonds (DDBs) are zero-coupon bonds issued at a discount and redeemed at face value. These do not carry periodic interest payments.

1. For bonds issued on or after 15 February 2002, interest income is recognised annually based on changes in market value, using values published by RBI or FIMMDA.
2. On redemption, the difference between redemption price and value on the last valuation date is treated as interest income.
3. If such bonds are transferred before maturity, the difference between the sale price and cost of acquisition (adjusted for previously taxed income) is treated as capital gains.
4. For bonds issued before 15 February 2002, the entire difference between the redemption value and issue price is taxed as interest income in the year of redemption.
5. Small non-corporate investors holding bonds of up to ₹1,00,000 face value may opt to defer taxation until redemption.

Conclusion

The taxation of interest on securities under the Income-tax Act represents a structured approach to capturing income earned from financial instruments in both the public and private sectors. It ensures that income is appropriately taxed based on the nature and use of the security, the accounting method followed, and the timing of accrual or receipt. By providing flexibility in recognizing income, permitting specific deductions under Section 57, and using grossing-up mechanisms for TDS, the framework achieves both procedural efficiency and substantive fairness.

At the same time, the legislation includes robust safeguards to prevent tax avoidance, especially through bond-washing and other artificial arrangements. Section 94 ensures that the person who enjoys the economic benefit of the security is taxed, even if the legal title is temporarily shifted. These provisions are a clear manifestation of the legal principle that substance should prevail over form in matters of taxation.

In the case of structured financial instruments like Deep Discount Bonds, the Act has adapted to contemporary financial practices by introducing valuation-based taxation and providing alternative mechanisms for small investors. This demonstrates the legislative intent to balance administrative convenience, economic realities, and taxpayer equity.

Judicial precedents have also played a significant role in clarifying the scope and interpretation of these provisions. Courts have consistently emphasized that income must be taxed in the hands of the person who ultimately benefits from it, and that any artificial structuring for tax benefit is liable to be disregarded.

Thus, the legal framework surrounding interest on securities is not only comprehensive but also adaptive. It provides clarity for taxpayers, predictability for investors, and a strong foundation for effective tax administration. Understanding these provisions is essential for students of law and commerce, tax practitioners, and policymakers engaged in fiscal governance.
