Form No. 3 Under Rule 7: Complete Guide to Accountant's Certificate for Zero Coupon Bond Issuers
Zero Coupon Bonds (ZCBs) occupy a unique position in India's tax-driven infrastructure financing landscape. To preserve their notified status and associated tax advantages, every eligible issuer must comply with an annual certification requirement — Form No. 3 — prescribed under Rule 7 of the Income-tax Rules. This guide provides a comprehensive walkthrough of the form's purpose, applicability, structure, filing mechanics, and the consequences of non-compliance, along with a curated FAQ section and practical checklist for issuers.
What Are Zero Coupon Bonds and Why Does Form No. 3 Matter?
Zero Coupon Bonds are debt instruments issued at a discount and redeemed at face value, with no periodic interest payments. Under Section 2(48) of the Income Tax Act, 1961 (corresponding to Section 2(112) of the Income-tax Bill, 2025), ZCBs notified by the Central Government carry specific tax treatment — notably, the discount is deductible under Section 36(1)(iiia) of the Income Tax Act, 1961 (or Section 32(1)(d) under the Income-tax Bill, 2025).
However, these benefits are conditional. The Central Government notifies a ZCB only when the issuer satisfies defined eligibility conditions and commits to deploying proceeds within prescribed timelines. To verify that this commitment is honoured year after year, Rule 7 mandates annual filing of Form No. 3 — a certificate issued by a qualified accountant confirming actual utilisation of ZCB proceeds.
Form No. 3 is not merely a procedural formality — it is the primary instrument through which regulatory authorities monitor whether infrastructure financing objectives of ZCBs are being met.
Legal Basis and Regulatory Framework
Form No. 3 draws its statutory authority from Rule 7 of the Income-tax Rules, which prescribes the conditions under which Zero Coupon Bonds may be notified by the Central Government. The broader legal framework is summarised below:
| Subject Matter | ITA 1961 Reference | Income-tax Bill, 2025 Reference |
|---|---|---|
| Definition of Zero Coupon Bond | Section 2(48) |
Section 2(112) |
| Discount deduction on ZCB | Section 36(1)(iiia) |
Section 32(1)(d) |
| Infrastructure Debt Fund provisions | Section 10(47) |
Schedule VII – Sl. 46 |
| Definition of Accountant | Section 288(2) |
Section 515(3)(b) |
Rule 7 specifically governs:
- Eligibility criteria for ZCB notification
- Minimum investment thresholds and utilisation timelines
- Sinking fund maintenance obligations for Infrastructure Debt Funds
- Annual compliance reporting through Form No. 3
Who Is Required to File Form No. 3?
Every entity that has issued a ZCB notified by the Central Government must file Form No. 3 for each tax year in which utilisation of bond proceeds is required to be reported. The eligible categories of issuers include:
- Infrastructure Capital Companies
- Infrastructure Capital Funds
- Infrastructure Debt Funds (IDFs)
- Public Sector Companies
It is important to note that the obligation is entity-specific and annual — it does not arise only once at the time of issuance but continues throughout the entire investment period defined under Rule 7.
Who Must Certify Form No. 3?
The certificate must be issued by an accountant as defined under Section 515(3)(b) of the Income-tax Bill, 2025, which corresponds to the Explanation to Section 288(2) of the Income Tax Act, 1961. The accountant is responsible for:
- Examining the issuer's books of accounts
- Verifying investment details and amounts
- Confirming adherence to the utilisation timelines prescribed under
Rule 7 - Generating and incorporating a UDIN (Unique Document Identification Number) before submission
