Section 177 - Limitation on interest deduction in certain cases
This is a thin-capitalisation rule. It limits the timing of the interest deduction; it does not necessarily deny the amount forever because eligible excess can be carried forward.
Reviewed by CA Nikhil Gupta · Updated 9 October 2026
Current law and effective date
Section 177 is controlled against the consolidated Income-tax Act, 2025 as amended by the Finance Act, 2026. The Act and Income-tax Rules, 2026 operate from 1 April 2026; earlier years and saved proceedings require the repeal-and-savings framework rather than automatic migration.

Old-law bridge
section 94B
The old-law bridge is navigational, not automatic precedent transfer. Match the 1961 Act wording, saved proceedings, current 2025 Act text and effective date before importing an older interpretation.
Finance Act 2026 / current-law note
No section-specific Finance Act, 2026 textual substitution is separately flagged for section 177; the consolidated post-Finance-Act-2026 text remains the controlling version and must be used instead of pre-1 April 2026 extracts.
Professional alert

Worked application
AE interest is ₹14 crore and 30% of EBITDA is ₹9 crore. The first limb produces ₹5 crore and the AE-interest limb is ₹14 crore; excess interest is ₹5 crore, subject to the statutory exclusions and full computation.
Evidence / compliance checklist
- debt and guarantee agreements (section 177 evidence control 1).
- AE relationship memo (section 177 evidence control 2).
- EBITDA reconciliation (section 177 evidence control 3).
- interest classification (section 177 evidence control 4).
Common mistake
A common section 177 error is to apply the old-law label or headline rate without rebuilding the current statutory conditions. For “Limitation on interest deduction”, the safer control is to test the exact taxpayer/transaction facts, the operative tax year, every linked Rule/Form and the Finance Act 2026 consolidated wording. Application caution Banking, insurance, specified IFSC Finance Companies, notified NBFC classes and certain Indian banking-PE lender debt are excluded under the exact statutory and Rule 126 conditions.
Recommended approach
For section 177, start with the legal trigger in “Limitation on interest deduction”, document the evidence for that trigger, then run the computation or procedural step against the current text. As a cross-check, verify this provision-specific checkpoint: Interest limitation applies where covered annual interest or similar expenditure exceeds Rs 1 crore.
Thresholds, periods and timing checkpoints
- Interest limitation applies where covered annual interest or similar expenditure exceeds Rs 1 crore.
- Excess interest is broadly the lower of interest above 30% of EBITDA and interest payable to associated enterprises under the statutory formula.
- Disallowed interest may be carried forward for up to eight tax years, subject to the annual cap.

FAQs
Does an old Income-tax Act, 1961 case automatically decide section 177?
No. The old-law bridge helps research, but transferability depends on materially matching language, transition rules and any Finance Act 2026 change.
Which text should be quoted in advice or litigation?
Quote the consolidated official statute for the relevant tax year. If this page presents a provision summary rather than complete statutory text, use the official consolidated Act for verbatim legislative language.
