Is there any remedy available under the act, if a person filed inaccurate or defective statement?
If any person, after filing the statement, comes to know or discovers any inaccuracy in the information provided in the statement, he shall inform such inaccuracy to the prescribed income-tax authority within a period of ten days and furnish the correct information in such manner as may be prescribed. 

On the other hand, the prescribed income-tax authority may also intimate the defect to the person and give him an opportunity of rectifying the defect within a period of thirty days from the date of such intimation or within such extended period as may be allowed by prescribed income-tax authority.

However, if a person fails to rectify the defect within the said period than the provisions of this Act shall apply as if such person had furnished inaccurate information in the statement.​
