    What is a Defective Return Notice Under Section 139(9)? – Complete Guide by My Startup Solution

    It is mandatory to file an Income Tax Return (ITR) by every taxpayer in India. While filing the return, there are some common minor mistakes committed by most taxpayers which include entering incorrect data, omission of sources of income, selecting the wrong ITR form, etc. Upon finding any errors in your return filing, the income tax department issues a Defective Return Notice Under Section 139(9). This means that your filed return suffers from some defects which must be rectified by you in the required time period. Knowing about what is a Defective Return Notice Under Section 139(9) is very crucial as it may render your income tax return invalid. My Startup Solution assists you in comprehending notices and rectifying errors.

    Understanding Defective Return Notice Under Section 139(9)

    A Defective Return Notice is issued by the Income Tax Department in case there are any errors or defects in the return filed by the taxpayer. In such cases, the Income Tax Department allows the taxpayer to rectify the error(s) and re-submit the return within the specified period of time. This is not to penalize but to ensure that all the details provided by the taxpayer are correct. This Defective Return Notice needs to be taken care of by the taxpayer at the earliest.

    Why Does the Income Tax Department Issue a Defective Return Notice?

    The Income Tax Department issues this notice when the information provided in the return is not sufficient for processing. This exercise is meant to enable taxpayers to rectify any errors before considering the return to be invalid. It involves the review of the return by the Income Tax Department in comparison with data available on Form 26AS, AIS, and TDS accounts among others. In case of any discrepancies, a notice under section 139(9) could be issued.

    Common Reasons for Receiving a Notice Under Section 139(9)

    Many taxpayers receive defective return notices due to simple filing mistakes. Here is some common reasons include:

    • Filing the wrong ITR form
    • Incorrect PAN or name details
    • Missing mandatory fields in the return
    • Tax paid but income schedules left blank
    • Claiming TDS credit without reporting related income
    • Mismatch between Form 26AS and reported income
    • Incorrect reporting of deductions and exemptions
    • Failure to mention the details of Profit & Loss Account/Balance Sheet in relation to Business Income

    These errors might lead the department to send an automatic notification.

    Time Limit to Respond to a Defective Return Notice

    The Income Tax Department generally allows taxpayers 15 days from the date of receiving the notice to rectify the defects. The period may vary if the department grants an extension upon request. It would not be wise to leave everything till the last day since there may be the need for more time to collect papers and make sure that all information provided is accurate. This way, the return will remain valid throughout the process.

    Important Documents Required for Rectification

    Before responding to the notice, taxpayers should gather all necessary documents. These may include:

    • Form 26AS
    • Annual Information Statement (AIS)
    • Salary slips
    • Bank statements
    • TDS certificates
    • Profit and Loss Account
    • Balance Sheet
