What Is a Defective Return?
A defective return is not a penalty notice, but a flag from the Income Tax Department indicating that your filed return is incomplete or has inconsistencies. Under Section 139(9) of the Income Tax Act, a notice is sent to your registered email ID if errors
are found, giving you an opportunity to correct them. Typically, you have 15 days to respond and rectify the defects. If you fail to do so, your ITR will be treated as invalid, as if you never filed it at all, which can lead to penalties, loss of refund eligibility, and inability to carry forward losses.
Mistake 1: Mismatching Income with Form 26AS and AIS
One of the most common triggers for a defective return notice is a mismatch between the income you declare and the data available with the tax department in your Form 26AS and Annual Information Statement (AIS). Your Form 26AS contains details of all tax deducted at source (TDS) on your behalf, while the AIS provides a comprehensive view of your financial transactions. Claiming TDS credit for an income you forgot to report is a major red flag for the system. Before filing, always reconcile your income details with these documents to ensure consistency.
Mistake 2: Choosing the Incorrect ITR Form
The Income Tax Department has different ITR forms for different categories of taxpayers and income sources. For instance, a salaried individual with no capital gains files ITR-1, but if they have income from capital gains, they must use ITR-2. Using the wrong form is a frequent error made in a last-minute rush. If you have business income, freelance earnings, or foreign assets, your form requirement changes. Filing with an incorrect form will likely result in your return being flagged as defective.
Mistake 3: Forgetting to Report All Income Sources
Many taxpayers meticulously report their salary but forget to include income from other sources, assuming small amounts don't matter. However, interest from savings accounts, fixed deposits, rental income, or dividends must all be declared. Since these are linked to your PAN, the tax department's systems can easily spot the omission through your AIS. Failing to disclose all income can lead to a defective notice and potential scrutiny for income concealment.
Mistake 4: Incorrect Personal and Bank Details
A simple typo in your personal information can cause significant issues. An incorrect name, PAN, or date of birth can delay processing. More critically, providing the wrong bank account number or an invalid IFSC code will inevitably delay or prevent you from receiving a refund. It is also mandatory to pre-validate the bank account in which you wish to receive your refund. Double-checking these seemingly minor details is a crucial step before submission.
Mistake 5: Not Filling Mandatory Schedules
Certain ITR forms require you to fill out specific schedules depending on your income profile. For example, if you have business income, you must fill out the Balance Sheet and Profit & Loss account sections. Likewise, if you have capital gains or foreign assets, the relevant schedules (like Schedule CG or Schedule FA) must be completed. Leaving these mandatory sections blank is a surefire way to have your return declared defective.
