Procedure to be followed by the assessing authority

(1) Every dealer who is liable to pay tax under this Act shall submit such return or returns relating to his turnover in such manner and within such period as may be prescribed. (2) If the assessing authority is satisfied that any return submitted under sub-section (1) is correct and complete, it shall assess the dealer on the basis thereof. (3) If no return is submitted by the dealer under sub-section (1) within the prescribed period, or if the return submitted by him appears to the assessing authority to be incorrect or incomplete, the assessing authority shall, after making such enquiry as it may consider necessary and after taking into account all relevant materials gathered by it, assess the dealer to the best of its judgment: Provided that before taking action under this sub-section the dealer shall be given a reasonable opportunity of being heard and, where a return has been submitted, to prove the correctness or completeness of such return.
