The genuineness of the excise invoice-cum-gate pass which was considered by the CTO is not in dispute. One of the invoices, i.e., Excise Invoice No.104, dt.31.08.94, raised on M/s. Indian Drugs and Pharmaceuticals Limited, Balanagar, Hyderabad, on a perusal lay bare that the total assessable value is Rs.2,48,720/- and that the basic excise duty and sales tax collections are Rs.24,872/- and Rs.11,408/- respectively. Therefore, the total value for which the invoice was raised is Rs.2,85,000/-. The sale price is also Rs.2,85,000/, which included excise duty as well as sales tax. Had the appellant not collected sales tax, the sale price would have been mentioned as Rs.2,73,592/- after excluding Rs.11,408/- viz., the sales tax collection. It is not in dispute that the corresponding commercial invoice also disclosed the same sale price of Rs.2,85,000/- which is equivalent to the value in the aforementioned excise invoice. Therefore, the contention that the excise invoice–cum-gate pass was raised only for the purpose of paying basic excise duty at the rate of 10% on the assessable value of the bulk drugs and that the central sales tax component and sales tax component are separately shown for the purpose of paying the excise duty and that the appellants have not collected sales tax from the buyers of bulk drugs cannot be countenanced. It is an admitted fact that the appellant in its books of account had not segregated and had not separately posted the sale price and the sales tax. Whether the sales tax is separately shown either in the commercial invoice or books of account is immaterial and what is relevant is the fact that the sales tax was collected from the customers of the appellant. The fact that remains is that the sale price shown in the commercial invoice is inclusive of sales tax. Admittedly, the sales are made by the appellant to the distributors who are its consumers. The appellant, being a small scale industry, which is availing incentive in terms of the G.O.Ms.No.498, is not entitled to collect the sales tax. Section 30B of the APGST Act, which deals with prohibition against collection of tax in certain cases, clearly mandates that no dealer shall collect any sum by way of tax, in respect of sale or purchase of any goods, which are not liable to tax under this Act. Further, Section 30C which deals with imposition of penalty for contravening certain provisions ordains that if any person collects tax in contravention of the provisions of Section 30B, any sum so collected shall be forfeited either wholly or partly to the State Government and in addition he shall be liable to pay a penalty of an amount not exceeding two thousand and five hundred rupees.
