Tax concession confined to basic sales tax; separate additional sales tax levy remained payable under the statute.

A notification reducing the rate of tax under the Kerala General Sales Tax Act applied only to the basic tax expressly covered by it and did not extend to additional sales tax levied separately under section 5D. Section 5D created an independent levy computed as an extra charge on the tax payable under sections 5 and 5A, so the concessional rate could not be used to reduce that additional component unless the notification expressly so provided. The Commissioner's clarification was therefore legally correct, and the challenge failed on merits.

Issues: Whether the reduction in rate of tax granted under the notification issued under section 10 of the Kerala General Sales Tax Act, 1963 extended to the additional sales tax levied under section 5D of the same Act.

Analysis: The notification granted a concession only in respect of the rate of tax otherwise payable on sales covered by the notification. Section 5D created a separate and independent levy by increasing the tax payable under sections 5 and 5A by an additional sales tax at the rate of fifteen per cent. The reduced rate under the notification could therefore operate only on the basic tax liability and not on the additional sales tax, which was not itself a rate of tax but a distinct levy calculated after determining the tax under sections 5 and 5A. The clarification issued by the Commissioner accordingly reflected the correct legal position.

Conclusion: The notification did not exempt or reduce additional sales tax under section 5D, and the clarification was upheld against the assessee.

Final Conclusion: The challenge failed on merits, and the petition was dismissed with the Commissioner's view sustained.

Ratio Decidendi: A notification granting reduction in the rate of tax applies only to the basic tax rate it expressly covers and does not, unless expressly provided, extend to a separate statutory levy calculated as an additional tax on the tax already payable.
