Transfer pricing and deduction principles clarified on revised returns, R&D approval timing, section 80IA profit computation, and section 10B eligibility.

A notice issued under section 143(2) on the original return remained valid after a revised return, because the assessment had already been validly initiated and no fresh notice was required. Weighted deduction under section 35(2AB) depended on timely initiation of the approval process: it was denied for the year where the application was made after the year ended, but allowed where the application was filed within the relevant year and approval followed later. For section 80IA(5), eligible profits could not be reduced by notional re-set-off of losses already absorbed elsewhere. Interest-free advances to an associated enterprise required arm's length determination under transfer pricing rules. Deduction under section 10B was upheld despite earlier years' losses and a Form 3CD omission.

Issues: (i) Whether a notice under section 143(2) issued on the original return remained valid notwithstanding a subsequent revised return; (ii) whether weighted deduction under section 35(2AB) was allowable for the relevant assessment years where approval of the prescribed authority was obtained during the later year but the application was made during the previous year; (iii) whether allocation of windmill-related expenses and notional carry forward of earlier years' losses for deduction under section 80IA(5) were justified; (iv) whether notional interest on advances to an associated enterprise could be added without determining arm's length price under transfer pricing provisions; and (v) whether deduction under section 10B could be denied on the ground of earlier years' losses and absence of declaration in Form 3CD.

Issue (i): Whether a notice under section 143(2) issued on the original return remained valid notwithstanding a subsequent revised return.

Analysis: The notice under section 143(2) was issued and served within the statutory time limit, thereby validly assuming jurisdiction for assessment. The later revised return did not render the original notice ineffective. Since the revised return was only a correction of the original return and the assessment proceedings were already pending, no fresh notice on the revised return was required.

Conclusion: The issue was decided against the assessee.

Issue (ii): Whether weighted deduction under section 35(2AB) was allowable for the relevant assessment years where approval of the prescribed authority was obtained during the later year but the application was made during the previous year.

Analysis: The deduction under section 35(2AB) depends on the existence of approval for the in-house research and development facility, and the date of approval is not the sole cut-off if the approval process is initiated during the relevant previous year. For the later assessment year, the application for approval had been made within the previous year and the approval was granted during that year. For the earlier assessment year, however, the application itself was made only after the relevant previous year had ended, so the claim could not be allowed for that year.

Conclusion: The claim was rejected for the earlier assessment year and allowed for the later assessment year, partly in favour of the assessee.

Issue (iii): Whether allocation of windmill-related expenses and notional carry forward of earlier years' losses for deduction under section 80IA(5) were justified.

Analysis: The finding on the windmill unit was that the disputed expenses were not shown to be attributable to that unit, and separate books were not decisive where the factual basis for allocation itself was absent. On the computation under section 80IA(5), earlier years' losses and depreciation already set off against other business income could not be notionally brought forward again for the purpose of reducing the eligible profit. The deduction was to be computed on the eligible business profit without such double adjustment.

Conclusion: The revenue's challenge on allocation of expenses failed, and the assessee's claim against notional set-off of earlier years' losses succeeded, substantially in favour of the assessee.

Issue (iv): Whether notional interest on advances to an associated enterprise could be added without determining arm's length price under transfer pricing provisions.

Analysis: Advances to the overseas subsidiary were treated as an international transaction falling within transfer pricing provisions. The question whether commercial expediency could exclude the transaction from scrutiny was not accepted as decisive. The proper course was to determine the arm's length price, including the appropriate rate of interest, in accordance with section 92 and refer the matter to the Transfer Pricing Officer.

Conclusion: The deletion of the addition was not sustained in full and the matter was remanded for arm's length price determination, partly in favour of the revenue.

Issue (v): Whether deduction under section 10B could be denied on the ground of earlier years' losses and absence of declaration in Form 3CD.

Analysis: Once the assessee had opted out of the section 10B regime for the earlier years, the losses and unabsorbed depreciation of those years could not be notionally forced into the computation for the year in which deduction was claimed. The objection based only on non-reflection in Form 3CD was treated as technical and not fatal where the opt-out declarations were otherwise available.

Conclusion: The assessee was held entitled to the deduction, in favour of the assessee.

Final Conclusion: The cross appeals were disposed of with mixed reliefs: the assessee succeeded on the weighted deduction for the later year and on the section 10B claim, while the revenue succeeded only to the limited extent of transfer pricing remand; the remaining issues were decided against the revenue's additions.

Ratio Decidendi: A valid notice under section 143(2) on the original return retains efficacy after a revised return; approval under section 35(2AB) is not defeated by timing where the application is made within the relevant year; section 80IA deductions cannot be reduced by notional re-set-off of losses already absorbed elsewhere; and intra-group interest-free advances to an associated enterprise fall within transfer pricing scrutiny requiring arm's length determination.
