Method selection comes before arithmetic. The same method is not automatically suitable for every transaction, and a comparable must be adjusted for economically material differences where reliable adjustment is possible.

Old-law bridge
section 92C
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
Finance Act, 2026 amended section 165(7) by removing the former section 144 reference. The arm's-length-price machinery otherwise remains governed by the current methods, tolerance and prescribed Rules.
Professional alert
Application caution An enhancement resulting from section 165 does not support a Chapter VIII deduction on the enhanced income.

Common mistake
A common section 165 error is to apply the old-law label or headline rate without rebuilding the current statutory conditions. For “Determination of arm's length price”, 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 An enhancement resulting from section 165 does not support a Chapter VIII deduction on the enhanced income.
Recommended approach
For section 165, start with the legal trigger in “Determination of arm's length price”, 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: Recognised ALP methods include CUP, resale price, cost plus, profit split, TNMM and the prescribed other method.
Thresholds, periods and timing checkpoints
- Recognised ALP methods include CUP, resale price, cost plus, profit split, TNMM and the prescribed other method.

FAQs

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.
