Gross-turnover audit requirements may stand, but duplicate income-tax audit burden can be read down for compliance efficiency.

Section 10A of the Assam General Sales Tax Act, 1993 is analysed as a regulatory audit requirement based on gross turnover, and its inclusion of particulars relating to Central Sales Tax transactions is treated as information-gathering for compliance and revenue protection, not as a separate levy. The absence of a distinct penal provision is noted as insufficient, by itself, to invalidate the audit scheme. The provision is further read down to avoid duplicative compliance, so an audit already conducted under the Income-tax Act may satisfy the sales tax audit requirement if the prescribed reports under rule 19A are filed.

Issues: (i) whether the audit requirement under section 10A of the Assam General Sales Tax Act, 1993, based on gross turnover and extended to transactions touching the Central Sales Tax Act, was arbitrary or discriminatory; (ii) whether the absence of a separate penal provision for non-compliance with section 10A and rule 19A justified striking down the provisions; (iii) whether the audit requirement should be read consistently with the Income-tax Act so as to avoid duplication of audit.

Issue (i): Whether the audit requirement under section 10A of the Assam General Sales Tax Act, 1993, based on gross turnover and extended to transactions touching the Central Sales Tax Act, was arbitrary or discriminatory.

Analysis: The audit requirement was upheld as a valid classification based on gross turnover and not on taxable turnover alone. The statutory scheme permits regulation of dealers for registration, returns and allied compliance even where some transactions may be exempt or not liable to sales tax. Inclusion of particulars relating to Central Sales Tax transactions in the prescribed form was held to be for information and revenue-protection purposes and not a levy of tax under that Act.

Conclusion: The challenge to section 10A and rule 19A on the ground of arbitrariness and lack of nexus was rejected.

Issue (ii): Whether the absence of a separate penal provision for non-compliance with section 10A and rule 19A justified striking down the provisions.

Analysis: The absence of a distinct penalty mechanism did not render the audit provisions invalid. The Court held that a provision is not liable to be struck down merely because enforcement machinery or penal consequences are incomplete, though the legislature or authority may need to examine the practical working of the provision.

Conclusion: The impugned provisions were not quashed on the ground that no separate penalty was provided.

Issue (iii): Whether the audit requirement should be read consistently with the Income-tax Act so as to avoid duplication of audit.

Analysis: The Court found merit in the grievance that dealers already audited under the Income-tax Act should not be compelled to undergo a second full audit for the sales tax law. To avoid unnecessary burden, the Court read down section 10A and treated an audit conducted under the Income-tax Act as sufficient compliance, provided the prescribed reports under rule 19A were furnished.

Conclusion: Section 10A was read down to the extent that an Income-tax Act audit would satisfy the sales tax audit requirement, subject to filing the requisite reports.

Final Conclusion: The writ petitions succeeded only in part: the audit provision was sustained in principle, the challenge to invalidity failed on most grounds, but the provision was modified by judicial reading down to prevent duplicate audit burden.

Ratio Decidendi: A fiscal compliance provision may be upheld as a valid regulatory measure even if it covers exempt or non-taxable transactions and lacks a separate penalty, but where it imposes an avoidable duplicate audit burden, it may be read down to harmonise with another statutory audit already completed under a cognate law.
