Works contract taxation upheld in substance, but restrictive provisos and rules were struck down or read down to preserve validity.

After the constitutional amendment permitting taxation of works contracts, the State could levy tax on the transfer of property in goods involved in execution of such contracts. Section 5F was therefore upheld in substance, but provisos requiring transfer in the same form, excluding protected interstate purchases, and imposing an unreasonable burden to prove sub-contractor turnover were struck down or read down. Section 5G, providing composition as an alternative mode of tax payment, was upheld subject to deletion of the same unreasonable proof requirement. Section 5H, authorising tax deduction at source, was also upheld as a valid advance collection mechanism. Rule 6(2) was upheld with deletions, rule 6(3)(i) was read down, and rule 6(3)(ii) was upheld.

Issues: (i) Whether section 5F of the Andhra Pradesh General Sales Tax Act, 1957, imposing tax on transfer of property in goods involved in the execution of works contracts, was constitutionally valid and whether the restrictive words in its provisos could stand; (ii) whether section 5G providing for composition of tax was valid; (iii) whether section 5H providing for deduction of tax at source was valid; and (iv) whether rule 6(2) and rule 6(3) of the Andhra Pradesh General Sales Tax Rules, as amended, were valid.

Issue (i): Whether section 5F of the Andhra Pradesh General Sales Tax Act, 1957, imposing tax on transfer of property in goods involved in the execution of works contracts, was constitutionally valid and whether the restrictive words in its provisos could stand.

Analysis: The charging provision was upheld on the footing that after article 366(29A)(b) and the governing principles on works contracts, the State Legislature could levy tax on the transfer of property in goods involved in execution of works contracts. The Court held that the levy was not invalid merely because it departed from a single-point pattern, because the Legislature could create a separate taxable class for works contracts and prescribe a uniform rate for goods involved therein. However, the provisos could not control the charging part in a manner inconsistent with the constitutional and statutory scheme. The words requiring the goods to be transferred in the same form as purchased were found inconsistent with the main provision and with section 15 of the Central Sales Tax Act, 1956. The exclusion in the third proviso relating to goods purchased from other States could not be applied to transactions protected by Central sales tax principles and covered by C forms. The burden placed by the last proviso on the contractor to prove that the sub-contractor's turnover was included in the sub-contractor's return was held unreasonable.

Conclusion: Section 5F was upheld, but the offending words in the first and second provisos were struck down, the restrictive words in the third proviso were read down, and the challenged words in the last proviso were struck down.

Issue (ii): Whether section 5G providing for composition of tax was valid.

Analysis: The Court held that composition was only an alternative mode of payment for works contract turnover and did not impose tax beyond the charging section when read in context. The reference to total turnover was construed as referring to the turnover of the works contract itself and not to all turnover of the dealer. The objection based on inclusion of non-taxable components was rejected because the assessee voluntarily opted for composition in lieu of detailed assessment. The same unreasonable burden concerning proof of inclusion of the sub-contractor's turnover was held unsustainable, and the provision had to be read consistently with the charging section and the rules.

Conclusion: Section 5G was upheld, subject to deletion of the unreasonable requirement regarding proof of inclusion of the sub-contractor's turnover.

Issue (iii): Whether section 5H providing for deduction of tax at source was valid.

Analysis: The Court held that tax deduction at source under section 5H was not unconstitutional merely because it was an advance collection mechanism. The provision was capable of being worked in harmony with the charging section and the assessment rules, particularly if provisional assessment was communicated so that deduction would not exceed the ultimate liability. The absence of any mechanism was not accepted as a ground for invalidity because the rules supplied the machinery for return, provisional assessment and adjustment. The burden on the dealer to prove deduction and remittance was also not accepted as oppressive, since the statute itself required the deductor to issue a certificate containing the necessary particulars.

Conclusion: Section 5H was held valid.

Issue (iv): Whether rule 6(2) and rule 6(3) of the Andhra Pradesh General Sales Tax Rules, as amended, were valid.

Analysis: Rule 6(2) was upheld because the deductions it provided were broadly in line with the constitutional principles governing works contract taxation, but the offensive parts relating to proof of sub-contractor turnover and the stipulation that exempted goods must be transferred in the same form were required to be omitted. Rule 6(3)(i) was not struck down; instead, it was read down so that, in the case of contracts extending beyond one year, tax could attach only to goods actually supplied or used during the year and not to stock in hand. Rule 6(3)(ii), prescribing percentage deductions where actual valuation was not ascertainable, was upheld because estimation was permissible where accounts were not available or reliable and the assessees had not shown the prescribed percentages to be arbitrary.

Conclusion: Rule 6(2) was upheld with deletions, rule 6(3)(i) was read down, and rule 6(3)(ii) was upheld.

Final Conclusion: The works-contract levy was sustained in substance, but the Court neutralised the unreasonable and inconsistent restrictions in the provisos and rules by striking them down or reading them down, resulting in partial relief to the writ petitioners.

Ratio Decidendi: After the constitutional amendment permitting taxation of works contracts, the State may levy tax on the transfer of property in goods involved in execution of works contracts, but any proviso or rule that conflicts with the charging section, extends the levy to non-taxable components, or imposes an unreasonable burden on the assessee must be struck down or read down to preserve constitutional validity.
