Trade discount and first-point taxation principles protect deductible discounts and prevent double taxation on later sales.

Trade discount forming part of the commercial sale arrangement is deductible from taxable turnover when supported by the relevant records, and omission to disclose it in the original monthly return does not by itself defeat an otherwise admissible claim if revised returns are filed. Goods that have already suffered tax at the first point of sale cannot be subjected to tax again on later sales within the same series merely because the resale price is higher. The Tribunal's order was set aside to the extent it upheld the disallowance and additional levy, and the assessee's revision succeeded.

Issues: (i) Whether trade discount was a permissible deduction from the taxable turnover when not disclosed in the original monthly returns; (ii) Whether first-point tax paid goods could again be subjected to tax on subsequent sales merely because the later sale price exceeded the first-point purchase price.

Issue (i): Whether trade discount was a permissible deduction from the taxable turnover when not disclosed in the original monthly returns.

Analysis: Trade discount is deductible from gross taxable turnover where it is part of the sale arrangement and is supported by the relevant commercial arrangement and credit notes. The omission to show the deduction in the original return does not, by itself, justify disallowance where the claim is otherwise legally admissible and revised returns have been filed. The earlier binding and persuasive authorities on sales tax treatment of trade discount support this position.

Conclusion: The issue was answered in the negative and in favour of the assessee.

Issue (ii): Whether first-point tax paid goods could again be subjected to tax on subsequent sales merely because the later sale price exceeded the first-point purchase price.

Analysis: Once goods have suffered tax at the first point of sale under the applicable sales tax regime, they are not liable to be taxed again on subsequent sales within the same series merely because of a higher resale price. The earlier assessment and appellate orders in the assessee's own case for connected periods were relied upon to apply the same principle consistently.

Conclusion: The issue was answered in the negative and in favour of the assessee.

Final Conclusion: The Tribunal's order was set aside to the extent it upheld the disallowance and the additional levy, and the assessee's revision succeeded.

Ratio Decidendi: Trade discount forming part of the commercial sale arrangement is deductible from taxable turnover, and goods already taxed at the first point cannot be taxed again in subsequent sales within the same series.
