Commodities transaction tax requires collection by recognized associations with specified deposit, interest and return obligations. Commodities Transaction Tax (CTT) is levied on sales of commodity derivatives (excluding specified agricultural commodities) traded in recognized associations, with collection responsibility placed on the recognized association to collect from the seller. The tax is chargeable at prescribed rates on transaction value and is deductible under income-tax when related income is shown under business profits. Tax collected must be deposited within seven days after the month of collection, interest applies for late or short payment, and returns must be filed in Form No.1 by 30th June following the financial year.
