Works-contract tax deduction scheme upheld as constitutionally valid because statutory exclusions and certification machinery made the levy workable.

Section 41 of the Bihar Value Added Tax Act and Rule 29 of the Rules were treated as a valid deduction-at-source scheme for works contractors because the levy was confined by the opening words "subject to the provisions of section 6", which exclude inter-State sales, outside-State sales, and import-export transactions. Rule 29 was read to provide the operative machinery by excluding labour and service components, sub-contractor payments, specified charges, and exempt goods or transactions. The availability of certificates from the prescribed authorities, along with adjustment of the deducted amount against final assessment and refund of excess, supplied workable guidance and prevented arbitrary operation. The provisions were therefore held intra vires and beyond the challenge based on legislative competence and Article 14.

Issues: Whether Section 41 of the Bihar Value Added Tax Act, 2005 and Rule 29 of the Bihar Value Added Tax Rules, 2005 are constitutionally valid; whether the deduction at source mechanism for works contractors lacks a workable machinery or violates Article 14; and whether the provisions travel beyond the State's legislative competence by permitting deduction on transactions outside the taxing power of the State.

Analysis: Section 41 was construed as a deduction-at-source provision confined by the opening words "subject to the provisions of section 6", which exclude inter-State sales, outside-State sales, and import/export transactions from the levy. Rule 29 was read as supplying the detailed procedure and as expressly excluding labour charges, sub-contractor payments, planning and design charges, hire charges, consumables not transferred, establishment expenses relatable to labour and services, profits relatable to labour and services, and exempt goods or transactions. The availability of certificates from the prescribed tax authorities, together with adjustment of the deducted amount against the final assessment and refund of excess, was treated as adequate machinery and guidance. The Court held that the impugned provisions were materially different from the earlier struck-down recovery provisions because they contained express exclusions and a workable certification mechanism, and therefore did not impose tax beyond legislative competence or suffer from arbitrary and uncanalised operation.

Conclusion: The impugned provisions were held valid and intra vires, and the challenge to the deduction-at-source scheme failed.

Final Conclusion: The writ petitions were dismissed because the Court upheld the constitutionality and operation of the works-contract tax deduction framework under the VAT Act and the Rules.

Ratio Decidendi: A works-contract tax deduction provision is constitutionally sustainable if it is confined by express statutory exclusions for non-taxable transactions and is supported by a workable certification and adjustment mechanism that prevents levy on matters beyond the State's taxing power.
