Section 178 - Applicability of General Anti-Avoidance Rule
GAAR can operate despite other provisions of the Act. The authority may examine the whole arrangement, a single step, or only a part. This section opens the gateway; it does not itself establish that the arrangement is impermissible.

Current law and effective date
Section 178 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.

GAAR can operate despite other provisions of the Act. The authority may examine the whole arrangement, a single step, or only a part. This section opens the gateway; it does not itself establish that the arrangement is impermissible.
Who should use this section
Taxpayers and advisers assessing whether Chapter XI GAAR can be invoked for an arrangement or a step in an arrangement.
Old-law bridge
section 95
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 178; the consolidated post-Finance-Act-2026 text remains the controlling version and must be used instead of pre-1 April 2026 extracts.
Professional alert
Identify the arrangement and each step separately. Quantify the tax benefit by tax year and for all parties. Do not treat the existence of a tax benefit as conclusive. Apply section 179 and Rule 128.

Worked application
A commercially genuine acquisition contains one circular financing step inserted only to create an artificial deduction. Section 178 permits examination of that step without automatically condemning the entire acquisition.
Evidence / compliance checklist
- Identify the arrangement and each step separately (section 178 evidence control 1).
- Quantify the tax benefit by tax year and for all parties (section 178 evidence control 2).
- Do not treat the existence of a tax benefit as conclusive. Apply section 179 and Rule 128 (section 178 evidence control 3).
- Archive the prescribed Rule/Form output for section 178 together with the acknowledgement, filing date and underlying computation.
Common mistake
A common section 178 error is to apply the old-law label or headline rate without rebuilding the current statutory conditions. For “Applicability of General Anti-Avoidance Rule”, 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. Identify the arrangement and each step separately. Quantify the tax benefit by tax year and for all parties. Do not treat the existence of a tax benefit as conclusive. Apply section 179 and Rule 128.
Recommended approach
For section 178, start with the legal trigger in “Applicability of General Anti-Avoidance Rule”, 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: GAAR is a gateway Chapter and does not itself prove that an arrangement is impermissible.

FAQs
Does an old Income-tax Act, 1961 case automatically decide section 178?
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.
