Works contract turnover deductions include plant depreciation and labour-related establishment expenses, with revenue challenge rejected.

In a works contract valuation, deductions from taxable turnover extend to labour and service components, including proportionate depreciation on plant and machinery used exclusively for execution of the contract. The absence of an express statutory reference to depreciation did not bar the deduction where it followed the settled principle governing works contract computation. Expenses such as bank interest, postage, telephone, fuel and lubricants, and allied establishment costs were also deductible to the extent they were relatable to labour and services. The Tribunal's allowance of these deductions was upheld and the revenue challenge failed.

Issues: (i) Whether depreciation on plant and machinery used in execution of a works contract was deductible while computing taxable turnover; (ii) whether expenses such as bank interest, postage, telephone, fuel and lubricants, and allied establishment expenses were deductible as relatable to labour and services in the works contract.

Issue (i): Whether depreciation on plant and machinery used in execution of a works contract was deductible while computing taxable turnover.

Analysis: The value of goods involved in a works contract is determined by deducting from the value of the contract the charges relatable to labour and services, including charges for obtaining on hire or otherwise machinery and tools used for execution of the contract. The earlier principles governing works contract valuation were read to include proportionate depreciation of plant and machinery used exclusively for execution of the contract, even though the word "depreciation" was not expressly stated. The absence of an express provision in the State enactment did not prevent such deduction where the deduction was covered by the underlying principle laid down for works contract valuation.

Conclusion: The deduction on account of depreciation of plant and machinery was allowable and the challenge to that deduction failed.

Issue (ii): Whether expenses such as bank interest, postage, telephone, fuel and lubricants, and allied establishment expenses were deductible as relatable to labour and services in the works contract.

Analysis: Expenses of this nature, when incurred in relation to the execution of the works contract, fall within the scope of the contractor's establishment cost to the extent relatable to supply of labour and services. Such expenses are covered by the settled principles governing deduction of labour and service components from the contract value and do not warrant interference when already accepted by the Tribunal on the facts of the case.

Conclusion: The deductions allowed on these heads were upheld and the revenue's challenge failed.

Final Conclusion: The common legal questions were answered against the revenue, the Tribunal's orders were sustained, and the appeals were dismissed.

Ratio Decidendi: In computing taxable turnover under a works contract, deductions extend to all amounts falling within the labour and service components of the contract value, including proportionate depreciation of plant and machinery used for execution and establishment expenses relatable to such labour and services.
