74B Rectification of mistakes and Review

(1)  Notwithstanding anything contained to the contrary in section 34, the Commissioner may, at any time within four years from the end of the year in which any order passed by him has been served, on his own motion, rectify any mistake apparent on record and shall within the said period or thereafter rectify any such mistake which has been brought to his notice within the said period, by any person affected by such order.

(2) The provisions of sub-section (1) shall apply to the rectification of a mistake by the appellate authority or an objection hearing authority as they apply to the rectification of mistake by the Commissioner:

PROVIDED that where any matter has been considered and decided in any proceedings by way of objection or appeal or review in relation to any order or part of an order, the authority passing the order on objection, appeal or review, may, notwithstanding anything contained in this Act, rectify the order or part of the order on any matter other than the matter which has been so considered and decided.

(3) Where any such rectification has the effect of reducing the amount of the tax or penalty or interest, the Commissioner shall refund any amount due to such person in accordance with the provisions of this Act.

(4) Where any such rectification has the effect of enhancing the amount of the tax or penalty or interest or reducing the amount of refund, the Commissioner shall recover the amount due from such person in accordance with the provisions of this Act.

(5) Save as provided in the foregoing sub-sections, and subject to such rules as may be prescribed, any assessment or re-assessment made or order passed under this Act or the rules made thereunder by any person appointed under section 66 may be reviewed by such person suo motu or upon an application made in that behalf.
