Revise the defective ITR within 15 days of notice addressing the defects
If you make any mistake in filing income tax return (ITR), then you will get a defective return notice as per Section 139(9) of Income Tax Act to rectify defects within 15 days from the date of receiving such intimation. The assessing officer can also allow extended period on the application. If you do not rectify the defects within this period then it would be deemed that you have not filled any return of income.
Reasons for notice
An intimation from the Income Tax Department is sent to a taxpayer when the assessing officer has found error in the tax return filed.
(a) When return is not submitted in the prescribed form with all annexures and statements duly filled.
(b) ITR should be accompanied by proof of tax, if any claimed to have been deducted or collected at source and the advance tax and self assessment tax, if any claimed.
(c) In case the entity is maintaining regular books of accounts, ensure that copies of trading, profit & loss account, income and expenditure account, personal account of the partners (partnership firms), personal accounts (proprietary concern) and balance sheet are submitted.
