Rebate and taxable turnover limits under sales tax law must follow the exact scope of the statutory proviso.

Rebate under section 15 was treated as available where tax was paid in time and the return, though filed one day late, was accepted without best judgment assessment, supporting an implied extension of the filing period. The filing deadline was viewed as relevant to rebate administration, not as an absolute bar destroying substantive entitlement. The proviso to section 7(2)(b) was confined to sales of goods purchased for resale or packing without manufacture, and did not extend to the sale price of bran manufactured from tax-free raw wheat. Manufactured product proceeds could not be added to taxable turnover under that proviso.

Issues: (i) Whether the assessee was entitled to rebate under section 15 despite filing the return one day after the prescribed period, where the tax had been paid in time; (ii) Whether the sale price of bran manufactured from tax-free raw wheat could be added to the assessee's taxable turnover under the second proviso to section 7(2)(b) of the Bihar Sales Tax Act, 1959.

Issue (i): Whether the assessee was entitled to rebate under section 15 despite filing the return one day after the prescribed period, where the tax had been paid in time.

Analysis: Section 15 allowed rebate on the amount of tax admitted to be due in the return furnished within the prescribed or extended period and paid under section 20(2). The return was accepted and assessment was not made on best judgment, which supported the inference that the period for filing the return had been impliedly extended. The filing of the return was treated as relevant to the allowance of the rebate, not as a rigid condition destroying the substantive entitlement where tax had already been paid within time.

Conclusion: The rejection of rebate was not justified and the answer was in favour of the assessee.

Issue (ii): Whether the sale price of bran manufactured from tax-free raw wheat could be added to the assessee's taxable turnover under the second proviso to section 7(2)(b) of the Bihar Sales Tax Act, 1959.

Analysis: The second proviso to section 7(2)(b) applied only to sales covered by clause (b), namely goods purchased for resale or packing without undergoing manufacture. Purchases of raw materials for processing or manufacture under the exemption notification fell within section 7(2)(a) and outside the proviso. In any event, the proviso dealt with the sale price of the goods purchased, not the sale price of manufactured products such as bran. The assessee's contravention, if any, might attract other consequences, but not inclusion of the bran sale proceeds in taxable turnover under that proviso.

Conclusion: The addition of the sale price of bran to taxable turnover was unlawful and the answer was in favour of the assessee.

Final Conclusion: Both reference questions were answered against the taxing authority, and the assessee obtained the relief claimed on the two substantive points decided.

Ratio Decidendi: A proviso must be confined to the class of transactions and goods to which its language clearly applies, and a dealer's taxable turnover cannot be enlarged by adding the sale price of manufactured products when the provision speaks only of the goods originally purchased.
