Any apparent mistake that could be rectified under Section 154, an authority from Income Tax may do that by any of the following ways:
1) Any order could be amended that passed under the provisions (any of them) of Income Tax Act, 1961
2) Either a deemed intimation or an intimation that was sent under the Section 143(1), could be amended
3) Any intimation that was sent under the Section 200A (1), could be amended (Note: Section 200A is meant to deal with the processing of ‘Tax Deducted at Source’ cases i.e. TDS Returns). Any correction required for calculation error in TDS form is done or correction of any incorrect claim in TDS statement is processed under Section 200A.
4) Any intimation that are sent under the Section 206CB could be amended (Section 206CB of the Finance Act, 1995 is meant to process the errors in TCS statements)
Please note that after rectification of the mistake(s), if the taxpayer’s tax liability is increased or the amount of refund is reduced, the taxpayer will get an opportunity to express his/her points.
