Section 179 - Impermissible avoidance arrangement
Two limbs are required: the main-purpose tax-benefit test and at least one of four tainted-element tests. A tax-motivated step can trigger a rebuttable presumption even when the wider transaction has a commercial objective.

Current law and effective date
Section 179 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.

Who should use this section
Parties to an arrangement where the main purpose and statutory tainted-element tests may produce an impermissible-avoidance finding.
Old-law bridge
section 96
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 179; the consolidated post-Finance-Act-2026 text remains the controlling version and must be used instead of pre-1 April 2026 extracts.
Professional alert
Document the non-tax commercial objective before execution. Test all four tainted elements; one is enough after the main-purpose test. Preserve evidence capable of rebutting the step-level presumption.

Worked application
A group establishes a genuine regional business, but inserts a one-day conduit solely to access a treaty rate. The commercial purpose of the wider expansion does not by itself displace the step-level presumption.
Evidence / compliance checklist
- Document the non-tax commercial objective before execution (section 179 evidence control 1).
- Test all four tainted elements; one is enough after the main-purpose test (section 179 evidence control 2).
- Preserve evidence capable of rebutting the step-level presumption (section 179 evidence control 3).
- Archive the prescribed Rule/Form output for section 179 together with the acknowledgement, filing date and underlying computation.
Common mistake
A common section 179 error is to apply the old-law label or headline rate without rebuilding the current statutory conditions. For “Impermissible avoidance arrangement”, 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. Document the non-tax commercial objective before execution. Test all four tainted elements; one is enough after the main-purpose test. Preserve evidence capable of rebutting the step-level presumption.
Recommended approach
For section 179, start with the legal trigger in “Impermissible avoidance arrangement”, 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: Impermissible-avoidance analysis requires the main-purpose tax-benefit limb plus at least one statutory tainted-element condition.

FAQs
Does an old Income-tax Act, 1961 case automatically decide section 179?
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?
