Additional consideration for purchased goods forms part of turnover when post-contract payments are directly linked to supply.

Extra amounts paid by a dealer to sugarcane growers as bonus, freight or lorry charges formed part of the purchase turnover because they were directly linked to the quantity of cane supplied and operated as additional consideration for the goods. Payments made after the original contract are included in turnover where they are not voluntary ex gratia amounts but are in substance part of the price payable for the purchase. The aggregate amount for which the sugarcane was bought was therefore liable to tax under the Karnataka Sales Tax Act, 1957.

Issues: Whether the extra amounts paid by the dealer to sugarcane growers as bonus, freight or lorry charges formed part of the purchase turnover liable to tax under the Karnataka Sales Tax Act, 1957.

Analysis: The governing test was whether the payments were merely voluntary ex gratia amounts or were in substance part of the consideration for the sugarcane purchased. The payments were found to be directly connected with the quantity of sugarcane supplied and were not lump-sum or unrelated payments. The so-called bonus, freight and lorry charges were treated as additional price payable for the sugarcane and therefore as part of the aggregate amount for which the goods were purchased.

Conclusion: The extra payments formed part of the purchase turnover and were liable to tax.

Ratio Decidendi: Payments made after the original contract, if they are directly linked to the goods purchased and represent additional consideration for those goods, form part of turnover under the statutory definition of purchase price.
