Section 10A computation requires matching exclusions in export and total turnover, and profit-enhancing disallowances do not block deduction.

While computing the section 10A deduction, expenses excluded from export turnover for telecommunication and foreign currency items must also be excluded from total turnover, so the proportionate formula remains consistent; the assessee therefore succeeded on that point. A disallowance under section 40(a)(ia) for alleged non-deduction of tax at source on reimbursements to a foreign associated enterprise was treated as only increasing the undertaking's profits, and those enhanced profits were held to remain eligible for section 10A deduction because the statute contains no contrary exclusion. The revenue's appeal failed and the relief granted to the assessee was sustained.

Issues: (i) Whether, while computing deduction under section 10A, amounts excluded from export turnover for telecommunication and foreign currency expenses must also be excluded from total turnover; (ii) Whether disallowance under section 40(a)(ia) for non-deduction of tax at source on reimbursements to a foreign associated enterprise can be ignored while computing the deduction under section 10A.

Issue (i): Whether, while computing deduction under section 10A, amounts excluded from export turnover for telecommunication and foreign currency expenses must also be excluded from total turnover.

Analysis: Section 10A adopts a proportionate formula based on export turnover and total turnover. The Court applied the jurisdictional High Court ruling that what is excluded from export turnover cannot be retained in total turnover, because total turnover is made up of export turnover and domestic turnover and the formula must operate on a consistent basis. The exclusion of the specified expenses from the numerator therefore requires the same exclusion from the denominator.

Conclusion: The issue was decided in favour of the assessee. The revenue's challenge to the computation under section 10A failed.

Issue (ii): Whether disallowance under section 40(a)(ia) for non-deduction of tax at source on reimbursements to a foreign associated enterprise can be ignored while computing the deduction under section 10A.

Analysis: The Court held that it was unnecessary to finally decide whether the payment was reimbursement, fees for technical services, or otherwise taxable. Even if the amount was disallowed under section 40(a)(ia), that disallowance only enhanced the business profits of the undertaking. Since section 10A allows deduction on profits derived from export business and no provision excludes such enhanced profits from the computation, the deduction had to be granted on the increased profit base. The respondent was permitted to support the order under Rule 27 of the Income-tax (Appellate Tribunal) Rules, 1963.

Conclusion: The issue was decided in favour of the assessee. The disallowance under section 40(a)(ia) did not justify denial of the corresponding section 10A deduction.

Final Conclusion: The revenue's appeal was rejected, and the order granting relief to the assessee was sustained in full.

Ratio Decidendi: For section 10A computation, any amount excluded from export turnover must also be excluded from total turnover, and a disallowance that only increases business profits cannot be ignored while determining the deduction unless the statute so provides.
