Works contract deductions: declared-goods identity, registered-dealer purchase proof, labour-related profit exclusion, and consumables treated as deductible.

The note examines deductions in works contract taxation under section 3-B, focusing on declared goods, proof of purchase from registered dealers, and exclusion of labour and service components. It explains that declared goods may be taxed again only when they are converted into a commercially distinct commodity under a different sub-item of section 14, while a registered-dealer purchase condition operates as an evidentiary safeguard rather than a fresh levy. It also records that transfer value in a works contract includes profit relatable to labour and services, and that consumables consumed without transfer of property are deductible, subject to factual assessment in each case.

Issues: (i) Whether the requirement that declared goods must be used in the same form in which they were purchased, for deduction under section 3-B(2)(b), violates the prohibition against taxation at more than one stage. (ii) Whether the condition that the goods must be purchased from registered dealers liable to pay tax under the Act results in multiple taxation. (iii) Whether section 3-B(2)(b) and 3-B(2)(e) are invalid for not allowing deduction of the profit margin and transfer value relatable to goods and labour in works contracts. (iv) Whether cost of consumables not involving transfer of property in goods is deductible under section 3-B(2)(e) in computing taxable turnover.

Issue (i): Whether the requirement that declared goods must be used in the same form in which they were purchased, for deduction under section 3-B(2)(b), violates the prohibition against taxation at more than one stage.

Analysis: The deduction condition was examined in the context of declared goods under section 14 of the Central Sales Tax Act and the restriction in section 15(a) against taxation at more than one stage. The decisive principle applied was that where a commodity is converted into a distinct commercial commodity falling under a different sub-item of section 14, the later levy is not a second levy on the same commodity. The Court treated goods within the same sub-item as one taxable commodity, but held that conversion into a different sub-item breaks identity and permits taxation. Applying that principle, the condition in section 3-B(2)(b) was read as consistent with the statutory scheme.

Conclusion: The condition does not violate section 15(a) of the Central Sales Tax Act or article 286(3) of the Constitution and the challenge fails.

Issue (ii): Whether the condition that the goods must be purchased from registered dealers liable to pay tax under the Act results in multiple taxation.

Analysis: The Court treated this requirement as a machinery and evidentiary condition for claiming deduction, intended to ensure proof of antecedent taxable purchase and to prevent fraud and evasion. Failure to prove purchase from a registered dealer was held not to shift the point of taxation, but only to affect entitlement to deduction. The requirement was contrasted with a charging provision and was upheld as a legitimate rule of proof in fiscal legislation.

Conclusion: The condition is valid and does not amount to taxation at more than one stage.

Issue (iii): Whether section 3-B(2)(b) and 3-B(2)(e) are invalid for not allowing deduction of the profit margin and transfer value relatable to goods and labour in works contracts.

Analysis: The Court applied the constitutional measure of tax on works contracts as settled in the leading decisions on article 366(29-A)(b). It held that the value of goods involved in a works contract is arrived at by taking the value of the entire contract and excluding the labour and service components, including profit relatable to labour and services. On that basis, the phrase used in section 3-B(2)(b) was construed as covering transfer value and not merely cost price. Likewise, the expression in section 3-B(2)(e) was read as wide enough to exclude labour charges and other like charges, including profit attributable to labour and services.

Conclusion: Sections 3-B(2)(b) and 3-B(2)(e) are valid, and the deduction provisions are not unconstitutional for excluding or limiting profit margin relatable to labour and services.

Issue (iv): Whether cost of consumables not involving transfer of property in goods is deductible under section 3-B(2)(e) in computing taxable turnover.

Analysis: The Court held, as a matter of principle, that consumables such as water, electricity, fuel and similar items, to the extent they are consumed in execution of the works contract without transfer of property, fall within the class of labour and service-related deductions. It further observed that the specific question whether ink or dyes used in printing or dyeing are such consumables depended on factual assessment and should be decided by the assessing authorities on the evidence in each case.

Conclusion: Cost of consumables not involving transfer of property in goods is deductible, but the classification of ink or dyes as consumables was left to assessment proceedings.

Final Conclusion: The constitutional challenge to section 3-B failed in substance, and the provision was upheld as valid, though the application of the consumables deduction was left to be determined case by case in assessment.

Ratio Decidendi: In works contract taxation, declared goods may be taxed again only when the goods used are commercially distinct from the goods purchased under a different sub-item of section 14 of the Central Sales Tax Act, and deductible turnover must exclude the labour, service, and profit elements relatable to labour and services.
