The Income Tax Department issues notices under various sections to ensure compliance and accuracy in tax filings. One such notice that salaried individuals may receive is under Section 139(9), which indicates that the Income Tax Return (ITR) has been considered defective. This article provides a comprehensive, SEO-optimized guide on understanding, responding to, and preventing errors leading to a Section 139(9) notice.
What is a Notice Under Section 139(9)?
A notice under Section 139(9) is issued when the filed ITR has certain deficiencies, errors, or missing information, making it defective. The taxpayer is required to rectify the issues within the prescribed time to ensure the return is processed correctly. If the errors are not rectified, the return may be deemed invalid, which could result in penalties and legal consequences.
Why Did You Receive a Defective Return Notice?
Understanding the reasons behind a Section 139(9) notice can help taxpayers take corrective action effectively. Here are some common causes:
1. Mismatch Between Form 16 and Filed ITR
Employers issue Form 16, which contains details of your income and tax deductions. If your ITR does not match Form 16, the tax department may classify it as defective.
2. Non-Disclosure of Income
Failing to declare income from sources like fixed deposits, rental income, capital gains, or freelance work may trigger this notice.
3. Incorrectly Claimed Deductions
Deductions under Sections 80C, 80D, HRA, or LTA must match the supporting documents submitted. If deductions exceed eligibility or lack proof, the ITR may be flagged.
4. Use of Wrong ITR Form
Choosing the incorrect ITR form (e.g., using ITR-1 instead of ITR-2 for capital gains or multiple income sources) can make a return defective.
5. Errors in Tax Computation
Discrepancies in tax calculations, exemptions, or missing self-assessment tax payments often lead to an ITR being marked as defective.
6. Missing Financial Statements for Business/Professional Income
Individuals with business or professional income must file a balance sheet and profit & loss statement with their return. Failure to do so results in a Section 139(9) notice.
