  • Wrong basic details, like name, PAN, or address.

The notice will be sent to your registered email ID and can also be accessed through the Income Tax e-filing portal. After receiving the notice, you need to make the necessary corrections in the return within 15 days. In case you fail to rectify the errors on the ITR on time, you might face some consequences in the future. 

Let's now discuss the reasons for receiving a defective notice 139 (9) in detail. 

Did You Know

Section 139(9) of the Income Tax Act helps NRIs understand when their income tax return (ITR) may be considered defective due to errors or omissions. It explains common causes such as mismatches in income and tax details, missing audit reports, or incomplete disclosure of income. NRIs get a 15-day window to correct these defects after receiving the notice, allowing them to avoid penalties and ensure accurate tax compliance in India. This knowledge empowers NRIs to promptly address errors in their tax returns and safeguard their refunds and benefits.

What is the Reason for the Defective Notice u/s 139(9) of the Income Tax Act? 

The assessing officer may consider the following reasons, mistakes, or omissions while issuing an income tax defective return notice under Section 139(9):

  • Discrepancy in Name: When your name stated in the ITR doesn't match the name on the PAN card. 
  • Incomplete ITR: You must file the annexure, statements, and columns in the ITR. The ITR must be duly filed whenever needed. For instance, when you claim deductions u/s 80G. You are required to file the details in the relevant schedule correctly. 
  • Income Tax Audit: Suppose an audit is required from your side under Section 44AB. Then, the entire audit report, including profit and loss account, balance sheet, and auditors' report, must be provided. When these documents are not submitted or if you submit an incomplete audit report, you may receive a defective return notice.
  • Not Complying with Cost-Audit: If you fail to submit the "Cost Audit" as required by the Companies Act 2013. Then, you might receive a defective return notice. 
  • TDS and Income Mismatch: You have claimed the TDS as a refund. However, the corresponding income is not offered for tax in the return.
  • Not Maintaining Books of Accounts: You need to maintain regular books of account. It includes balance sheets, trading accounts, profit and loss accounts, etc. However, incomplete or non-submission of these may incur a defective return notice. 
  • Inaccuracies in the Presumptive Taxation Scheme: In case of presumptive taxation, furnishing a wrong calculation of presumptive income, not disclosing accurate details, or a discrepancy in gross receipts can lead to a defective return notice. For instance, if gross receipts are not stated in the profit and loss account, or the mentioned amount exceeds Rs. 2 crore in ITR 4, it may trigger a defective return notice. 
  • Missing Tax Information: It means that if taxes have been paid along with interest before filing the return. Also, if the details related to it are omitted in the ITR. It includes the BSR code, the Date of the Challan, and the Challan serial number. 

What Should You Do After Receiving a Notice Under Section 139(9)? 

Upon receiving a notice of an income tax defective return notice u/s 139(9), you need to revise your return within 15 days of the notice's receipt by the Income Tax Department. Alternatively, you can request an extension by submitting a written application to the Assessing Officer (A.O.). You can ask for more time to file a revised return.

It is often observed that even if a taxpayer rectifies the defect after the 15-day duration, the AO may still condone the delay and treat the return as valid. It applies if it is done before the assessment is finalized. 

However, if you don't respond within 15 days, you can request an additional extension to make the revisions. If your extension request is denied, the original return will be considered invalid. This situation could lead to consequences like accruing interest, not being able to carry forward losses, facing penalties, and losing specific exemptions. 

What Happens if You Don't Respond After Receiving a Notice for a Defective Return Under Section 139(9)? 

If you fail to respond to a defective return notice under Section 139(9) or to revise your income tax return (ITR) within the specified timeframe. Then, it will result in your defective return being classified as a non-filed or invalid return. The Income Tax Department will view this as if you have not submitted a return for that year. Consequently, it means that any potential refund you are due will not be processed. 

If your original ITR is deemed invalid, you can still file a belated return. However, this will incur a penalty fee to minimize further repercussions. 

How Will You Receive a Notice Under Section 139(9)?

You will get the notice u/s139(9) from the Income Tax Department via the email address you provided while filing your ITR. These notices typically come from the CPC. Also, the subject line will read "Communication u/s 139(9) for PAN AWZXXXXXXX for the A.Y. 2024-25". 

The notice is attached to the email and is password-protected. To open it, the password is your PAN in lower case, and your birth date in the format DD/MM/YYYY. 

For example, 

If your PAN is ABCDE1234F and your birth date is 01/01/2001, then the password to open the defective return notice will be abcde1234f01012001.
