Section 94B Interest Deduction Limitation (Thin Capitalisation): 30% EBITDA Caps & Cross-Border Debt Structuring
Updated: Sep 28
Multinational enterprises (MNEs) operating in India routinely utilize debt instruments, shareholder advances, and parent company corporate guarantees to fund domestic capital expenditure and working capital requirements. While debt financing offers inherent commercial agility, cross-border related-party debt has historically been vulnerable to base erosion through excessive interest deductions. In alignment with the OECD Base Erosion and Profit Shifting (BEPS) Action 4 recommendations, India enacted Section 94B of the Income-tax Act, 1961, establishing a rigorous thin capitalisation regime that caps allowable interest deductions at 30% of EBITDA.
Update — 28 September 2026: CBDT changed the specified ordinary AY 2026–27 tax-audit report deadline from 30 September to 21 October 2026 and the related audited return deadline from 31 October to 21 November 2026. Section 92E / Form 3CEB cases retain a separate timeline. Official Income Tax Department announcement.
For Chief Financial Officers, tax directors, and statutory auditors, navigating Section 94B requires an integrated approach that harmonizes international transfer pricing benchmarks, Reserve Bank of India (RBI) External Commercial Borrowings (ECB) limits, and mandatory disclosures under Clause 30B of Form 3CD.
Legislative Architecture & Applicability Thresholds
Section 94B applies to an Indian company or a Permanent Establishment (PE) of a foreign company in India that incurs deductible interest or similar consideration in respect of debt issued by a non-resident Associated Enterprise (AE).
#### 1. The ₹1 Crore Statutory De Minimis Threshold
Under Section 94B(1), the interest deduction limitation is triggered only when the total interest or similar consideration paid or payable to non-resident AEs exceeds ₹1 Crore (INR 10,000,000) in the relevant financial year. If aggregate related-party interest remains at or below ₹1 Crore, Section 94B disallowance does not operate, although arm's length pricing under Section 92C remains mandatory.
#### 2. Scope of 'Debt' and 'Associated Enterprise'
The definition of debt under Section 94B(5) is expansive, covering any loan, financial instrument, finance lease, financial derivative, or arrangement that gives rise to interest, discounts, or finance charges. The lender must qualify as an Associated Enterprise within the meaning of Section 92A.
#### 3. Deemed Associated Enterprise Debt (Third-Party Loans)
Crucially, Section 94B(1) contains a sweeping deeming fiction: where an Indian entity borrows funds from an independent, third-party lender (such as an overseas commercial bank), the debt is deemed to be issued by an Associated Enterprise if:
An AE provides an explicit or implicit corporate guarantee to the third-party lender; or
An AE deposits a corresponding and matching amount of funds with the lender (cash-collateralized or back-to-back lending).
Consequently, standard cross-border syndicated bank loans backed by parent guarantees fall directly within the crosshairs of Section 94B.
The Section 94B Computation Matrix: 30% EBITDA Cap
Where Section 94B applies, the allowable deduction for interest paid or payable to non-resident AEs is capped. The quantum of disallowance is mathematically computed as:
Formula: Disallowance = \min(Excess Interest, Total AE Interest)
Where Excess Interest is defined as:
Formula: Excess Interest = Total Interest Paid or Payable to Non-Resident AEs - (30\% × EBITDA)
If EBITDA is negative or zero, the entire amount of interest paid or payable to the non-resident AE is disallowed in the current assessment year.
#### Statutory EBITDA Computation
For the purposes of Section 94B, EBITDA is calculated strictly in accordance with tax principles rather than general financial accounting standards:
Formula: EBITDA = Net Profit Before Tax + Interest Expense + Depreciation + Amortisation
All figures must be derived from the computation of business income under Chapter IV-D of the Income-tax Act, prior to applying Section 94B disallowances.
Carry-Forward & Set-Off Mechanism: 8-Year Window
Recognizing that cyclical business downturns or initial gestation periods can artificially compress EBITDA, Section 94B(4) provides a relief mechanism:
8-Year Carry-Forward: Any interest disallowed under Section 94B can be carried forward to subsequent assessment years up to a maximum of 8 assessment years immediately succeeding the year of initial disallowance.
Subsequent Deduction: In a subsequent assessment year, the carried-forward interest can be claimed as a deduction against business profits, provided total interest deduction (current year AE interest + brought forward disallowed interest) does not breach the 30% EBITDA ceiling.
Hierarchy of Absorption: Current year interest takes statutory precedence; brought forward disallowed interest is absorbed only if headroom remains under the 30% threshold.
Interplay Between Section 92C Transfer Pricing & Section 94B
A critical source of audit friction is the sequence of adjustment between Transfer Pricing and Section 94B:
Step 1: Arm's Length Interest Rate Determination (Section 92C): The primary transfer pricing benchmark must be applied first. If an Indian borrower pays interest at 10% on a foreign currency loan, but the arm's length rate determined under Section 92C is 7%, the 3% difference is permanently disallowed as a primary transfer pricing adjustment under Transfer Pricing Audit Form 3CEB.
Step 2: Secondary Adjustment (Section 92CE): The 3% excess interest must be repatriated to India within 90 days, or subjected to an 18% imputed interest penalty as detailed in Transfer Pricing Secondary Adjustments under Section 92CE.
Step 3: Section 94B EBITDA Limitation: The 30% EBITDA cap is applied strictly on the re-computed arm's length interest (the 7% component). Any interest disallowed under Section 94B is not a permanent disallowance; it enters the 8-year carry-forward pool.
MNEs engaging in long-term debt structuring can secure bilateral certainty on interest spreads and benchmark spreads by entering into an Advance Pricing Agreement (APA) under Section 92CC.
Cross-Border Alignment: FEMA External Commercial Borrowings (ECB)
When structuring inbound shareholder debt, corporate treasuries must ensure dual compliance between Section 94B tax caps and Reserve Bank of India foreign exchange parameters:
All-In-Cost Ceilings: Under the RBI Master Direction, foreign currency ECBs are capped at benchmark SOFR + 500 bps, while INR-denominated ECBs are capped at benchmark yield + 450 bps.
Negative End-Use Restrictions: ECB proceeds cannot be utilized for equity investments, real estate trading, or working capital unless specifically authorized under the 10-year maturity track as examined in FEMA Guidelines on External Commercial Borrowings (ECB).
Tax Audit Disclosures: Form 3CD Clause 30B Checklist
Under Section 44AB, statutory tax auditors must provide detailed disclosures in Clause 30B of Form 3CD:
Expenditure by way of Interest / Similar Consideration: Exact quantitative verification of ledger balances for interest, guarantee fees, and debt arrangement charges paid to non-resident AEs.
EBITDA Computation Schedule: Reconciled schedule of Earnings Before Interest, Tax, Depreciation, and Amortisation based on computed business income.
Disallowed Interest Calculation: Quantitative determination of excess interest exceeding 30% of EBITDA.
Brought Forward and Carried Forward Schedule: Year-wise tracking of unabsorbed interest from prior assessment years, amounts set off during the year, and closing balances available for future carry-forward.
