GST on Corporate Guarantees: Rule 28(2) 1% Valuation & Circular 204 Defense Guide
Quick Summary & Key Takeaways (Featured Snippet)
1. The Corporate Guarantee Landscape: Schedule I Related-Party Transactions
In corporate India, parent holding companies routinely execute tripartite guarantee deeds with commercial banks to secure credit lines, working capital facilities, and term loans for their operating subsidiaries. Historically, these guarantees were furnished as intrinsic shareholder functions to lower group borrowing costs, with zero guarantee commission charged between related entities.
Under the Central Goods and Services Tax Act, 2017 (CGST Act), this commercial practice collided with Section 7(1)(c) read with Schedule I (Entry 2). Schedule I dictates that any supply of goods or services between related persons, when made in the course or furtherance of business, constitutes a taxable supply even if executed without any consideration.
2. Rule 28(2) Valuation Architecture: The 1% per Annum Deemed Value Rule
To end nationwide litigation regarding the open market value (OMV) of corporate guarantees, the GST Council introduced sub-rule (2) to Rule 28 of the CGST Rules vide Notification No. 52/2023-Central Tax (dated October 26, 2023), subsequent amended by Notification No. 12/2024-Central Tax:
Statutory Text of Rule 28(2):
"Notwithstanding anything contained in sub-rule (1), the value of supply of services by a supplier to a recipient who is a related person, by way of providing corporate guarantee to any banking company or financial institution on behalf of the said recipient, shall be deemed to be one per cent of the amount of such guarantee offered per annum, or the actual consideration, whichever is higher."
Applicable Tax Rate: 18% GST (9% CGST + 9% SGST for intra-state, or 18% IGST for inter-state).
3. CBIC Circular No. 204/16/2023 & 225/19/2024: Official Interpretations
The Central Board of Indirect Taxes and Customs (CBIC) issued two comprehensive circulars resolving operational ambiguities:
Clarified that Rule 28(2) applies prospectively from October 26, 2023. For periods prior to this date, valuation must follow general Rule 28 principles. Confirmed that personal director guarantees without consideration have an open market value of NIL.
Clarified that corporate guarantees represent a continuous supply of service. The 1% valuation must be calculated proportionally per annum over the actual tenure of the loan facility, rather than demanding 1% for all future years upfront.
4. Corporate Guarantees vs Director Personal Guarantees: The RBI Zero-Fee Safe Harbor
Tax authorities aggressively issued Show Cause Notices attempting to levy 18% GST on personal guarantees given by company promoters and Managing Directors. CBIC put an end to this controversy by relying on RBI banking norms:
The RBI Safe Harbor for Director Guarantees:
- Under RBI Master Circular on Guarantees, banks are strictly prohibited from paying any guarantee commission, fee, or remuneration to directors for furnishing personal guarantees.
- Because no consideration can legally be paid, the Open Market Value (OMV) of a director's personal guarantee under Rule 28 is legally treated as Zero (NIL).
- Consequently, no GST is payable on director personal guarantees, providing complete immunity to corporate promoters.
5. Cross-Border Guarantees: Foreign Parent Guarantees & Reverse Charge Mechanism (RCM)
When an international multinational corporation (MNC) headquartered in the US, Europe, or Japan guarantees a term loan sanctioned by an Indian bank to its Indian subsidiary:
- The transaction is classified as an Import of Service from a related party under Section 7(1)(c).
- The foreign parent cannot issue a domestic GST invoice.
- Under Section 9(3) of the CGST Act read with Notification No. 10/2017-IT(R), the Indian subsidiary must pay 18% IGST under Reverse Charge Mechanism (RCM) on the 1% deemed value.
- The Indian subsidiary can immediately claim 100% ITC of the RCM tax paid in the same GSTR-3B return.
6. Input Tax Credit (ITC) Fungibility: Second Proviso to Rule 28 Availability
For purely domestic group companies, GST on corporate guarantees represents a classic revenue-neutral pass-through:
When Parent Co raises a GST invoice charging 18% tax on 1% deemed value, Subsidiary Co avails 100% Input Tax Credit (ITC) under Section 16 of the CGST Act. In July 2024, the GST Council reinstated the second proviso to Rule 28, affirming that where the recipient subsidiary is eligible for full ITC, the value declared in the tax invoice shall be deemed to be the open market value, giving CFOs flexibility to avoid frivolous working capital lockups.
7. Amortisation of Guarantee Fee: Annual Billing vs One-Time Upfront Invoicing
Circular No. 225/19/2024-GST settled the accounting controversy regarding loan tenures:
The Annual Valuation Methodology:
If a parent company guarantees a 5-year loan of ₹100 Crores, the parent is NOT required to pay GST on ₹5 Crores upfront (1% × 5 years). Instead, the parent issues an annual invoice charging 1% on the active guaranteed amount for each financial year. If the loan is pre-paid or closed in Year 3, no GST is payable for Years 4 and 5.
8. Step-by-Step Corporate Guarantee Tax Computation & Invoicing SOP
Determine Active Guarantee Quantum
Obtain bank sanction letters and guarantee execution deeds. Identify the maximum sanctioned credit limit guaranteed during the financial year.
Compute 1% Deemed Taxable Value
Multiply the active guaranteed sum by 1% per annum. For intra-state groups, compute 9% CGST + 9% SGST; for inter-state groups, compute 18% IGST.
Issue GST e-Invoice & Avail ITC
Generate an IRN e-invoice under SAC code 997159 (Other financial services). Parent reports in GSTR-1; subsidiary avails 100% ITC in GSTR-3B.
9. Corporate Guarantee vs Bank Guarantee vs Director Guarantee Matrix
| Guarantee Type | Governing Provision | Deemed Valuation | GST Liability |
|---|---|---|---|
| Corporate Guarantee (Parent to Sub) | Rule 28(2) CGST Rules | 1% per annum of guaranteed amount | 18% GST (Forward Charge / RCM) |
| Director Personal Guarantee | Circular No. 204/16/2023 | NIL (Zero) | Exempt (0% GST) |
| Bank Guarantee (Commercial Bank) | Section 15 (Transaction Value) | Actual commission charged by bank | 18% GST charged on bank fee |
| Foreign Parent Corporate Guarantee | Import of Service / Rule 28(2) | 1% per annum deemed value | 18% IGST under RCM (Section 9(3)) |
10. Corporate Conglomerate Case Study: ₹100 Crore Subsidiary Loan Guarantee Defense
Case Study: Renewable Energy Group (Gujarat & Maharashtra)
A Mumbai-based parent holding company provided an irrevocable corporate guarantee of ₹100 Crores to State Bank of India for a solar project term loan sanctioned to its Gujarat special purpose vehicle (SPV) in FY 2024-25.
Deemed Value: 1% of ₹100 Crores = ₹1.00 Crore annual taxable value.
GST Invoiced: Parent issued an inter-state tax invoice charging 18% IGST = ₹18.00 Lakhs.
ITC Reconciliation: Gujarat SPV availed ₹18.00 Lakhs ITC in GSTR-3B to offset its transmission operations GST liability, achieving 100% compliance with zero net cash loss.
11. High-Risk Audit Pitfalls: Co-Borrower vs Guarantor Confusion & Section 74 SCNs
Pitfall 1: Confusing Joint Co-Borrowers with Guarantors
When parent and subsidiary are joint co-borrowers with joint and several primary liability to the bank, no guarantee service is supplied between them. Treating co-borrowing as a corporate guarantee leads to redundant tax payouts.
Pitfall 2: Omission of RCM Payment on Foreign Parent Guarantees
Indian subsidiaries often fail to self-assess RCM on offshore holding company guarantees. Audits routinely slap 18% tax demand plus mandatory 18% interest under Section 50, even though ITC would have been available.
12. Landmark Judicial Challenges: Delhi High Court & Punjab & Haryana HC Petitions
Rule 28(2) has been challenged on constitutional grounds across multiple High Courts (e.g. Sterlite Power Transmission vs Union of India before the Delhi High Court). Petitioners argue that fixing an arbitrary 1% deemed value violates Section 15 of the CGST Act (which requires transaction value) and exceeds the rule-making authority of the Executive. While courts have issued notices and granted interim relief against coercive recovery, prospective compliance with Rule 28(2) remains statutory law until struck down.
13. Synergy with Income Tax Transfer Pricing: Safe Harbour Rules vs GST 1% Deeming
Under Income Tax Safe Harbour Rules (Rule 10TD), the minimum corporate guarantee commission for international transactions is fixed at 0.50% per annum. However, under GST Rule 28(2), the deemed value is mandatorily fixed at 1% per annum. Taxpayers must reconcile this divergence to ensure that claiming safe harbor under Income Tax does not trigger an immediate 0.50% undervaluation notice under GST.
14. Decision Matrix: Structuring Corporate Guarantees (Letter of Comfort vs Guarantee)
Strategic Financial Structuring Options:
- Non-Binding Letter of Comfort (LoC): Optimal where bank accepts moral backing without legal debt assumption. 0% GST liability.
- Joint Co-Borrowing: Both parent and sub execute loan agreement jointly. Eliminates guarantee relationship entirely.
- Formal Corporate Guarantee: Issue annual GST invoice at 1% deemed value; recipient claims 100% ITC. Total tax neutrality.
