Turnover tax on gross sales upheld as a valid state levy, with classification and anti-passing-on rule sustained.

Turnover tax under section 6B of the Bengal Finance (Sales Tax) Act, 1941 and section 4AAA of the West Bengal Sales Tax Act, 1954 is treated as an additional levy on sales within the State taxing field, not as a tax on income. The restriction preventing dealers from passing the tax on to purchasers does not alter its character or invalidate the levy. Classification by gross turnover is upheld as a reasonable fiscal criterion, and challenges based on articles 254, 14, 19(1)(g), 301 and 51A are rejected. Non-taxable or non-leviable sales may also be included in gross turnover for determining liability to the turnover tax.

Issues: (i) Whether turnover tax imposed under section 6B of the Bengal Finance (Sales Tax) Act, 1941 and section 4AAA of the West Bengal Sales Tax Act, 1954 is a tax on sales within legislative competence and not a tax on income, and whether the prohibition against passing it on to purchasers is valid. (ii) Whether the impugned provisions are invalid for repugnancy under article 254 or as violative of articles 14, 19(1)(g), 301 and 51A of the Constitution of India, including the challenge based on the three-year continuance of liability and the classification of dealers by gross turnover. (iii) Whether non-taxable or non-leviable sales are to be included in gross turnover for the purpose of determining liability to turnover tax.

Issue (i): Whether turnover tax imposed under section 6B of the Bengal Finance (Sales Tax) Act, 1941 and section 4AAA of the West Bengal Sales Tax Act, 1954 is a tax on sales within legislative competence and not a tax on income, and whether the prohibition against passing it on to purchasers is valid.

Analysis: The charging provision was construed as an additional levy on the aggregate of sales effected by a dealer and not as a tax on income. The relevant constitutional entry permits a tax on the sale or purchase of goods, and the manner of computation by reference to turnover does not alter the character of the levy. A sales tax does not cease to be a sales tax merely because the dealer is prohibited from recovering it from the purchaser. The Court applied the settled principle that the legal incidence of sales tax falls on the dealer and the power to impose such tax is not conditional on permitting collection from the buyer.

Conclusion: The turnover tax is within legislative competence, is a tax on sales, and the prohibition on passing it on is valid.

Issue (ii): Whether the impugned provisions are invalid for repugnancy under article 254 or as violative of articles 14, 19(1)(g), 301 and 51A of the Constitution of India, including the challenge based on the three-year continuance of liability and the classification of dealers by gross turnover.

Analysis: The Court held that article 254 was not attracted in the manner suggested because the State enactment was essentially within the State taxing field and the ancillary restriction on recovery did not destroy its validity. The classification of dealers by gross turnover was upheld as a reasonable classification based on economic superiority and capacity to pay. The challenge under article 19(1)(g) failed because the levy was not shown to be confiscatory and the inability to pass on the tax did not convert it into a tax on income. The challenge under article 301 also failed because a reasonable taxing measure of this nature does not amount to a prohibition on free trade. The three-year continuation provision was treated as a permissible and pragmatic fiscal classification.

Conclusion: The impugned provisions are not invalid under article 254 or articles 14, 19(1)(g), 301 and 51A of the Constitution of India, and the continuance provision is valid.

Issue (iii): Whether non-taxable or non-leviable sales are to be included in gross turnover for the purpose of determining liability to turnover tax.

Analysis: The Court distinguished the earlier understanding that excluded non-taxable sales for charging purposes and applied the later binding explanation that such transactions may be taken into account for the limited purpose of identifying dealers liable to an additional turnover-based levy. The use of gross turnover for classification and threshold purposes was held to be permissible even though the underlying transactions themselves were not taxed.

Conclusion: Non-taxable or non-leviable sales can be included in gross turnover for determining liability to turnover tax.

Final Conclusion: The statutory scheme imposing turnover tax on dealers crossing the prescribed turnover threshold was upheld in substance, and the challenge to the levy failed in all material respects.

Ratio Decidendi: A turnover-based additional levy on sales is constitutionally valid when it remains within the State taxing entry, uses gross turnover only as a basis for classification and liability, and does not become invalid merely because the dealer is barred from collecting it from purchasers.
