Introduction
ITR filing season has started, and many taxpayers still make small but very common mistakes while filing their Income Tax Return. The problem is that these mistakes may look minor initially, but practically they can result in defective returns, notices from the Income Tax Department, refund delays, penalties, and unnecessary compliance issues.
The good thing is that most of these mistakes can be avoided very easily if taxpayers follow a few simple practical steps before filing the return.
One of the biggest practical realities is that many taxpayers focus only on filing ITR quickly but do not properly verify income details, applicable ITR forms, deductions, TDS entries, or e-verification requirements.
Main Discussion
1. Selecting the Wrong ITR Form
One of the most common mistakes people make while filing ITR is selecting the wrong ITR form.
Commonly Applicable ITR Forms
| ITR Form | Generally Applicable For |
| ITR-1 | Salary income and limited capital gains |
| ITR-2 | Multiple house properties and capital gains |
| ITR-3 | Business or professional income |
| ITR-4 | Presumptive business/professional income |
Practically, many taxpayers do not properly check which ITR is applicable and directly select the wrong form.
Practical Impact
| Mistake | Possible Consequence |
| Wrong ITR Selection | Defective return |
| Incorrect filing | Return revision |
| Serious mismatch | Departmental notice |
2. Income Mismatch with AIS and Form 26AS
AIS and Form 26AS practically work like master data available with the Income Tax Department.
Commonly Reflected Transactions
| Transaction Type | Common Reporting Source |
| Bank Interest | Banks |

| Business Receipts | GST / Other systems |
3. Not Reporting All Income
Income Commonly Missed

4. Wrong or Fake Deduction Claims
Examples of Wrong Claims

| Unsupported deductions | Penalty risk |
Under-reporting may attract penalty up to 50%, while misreporting with fake documents may attract penalty up to 200%.
5. Filing Near Deadline and Forgetting E-Verification
Practical Risks of Last-Minute Filing
| Issue | Practical Impact |

Conclusion
ITR filing is not just about submitting the return quickly. Correct reporting, proper reconciliation, genuine deduction claims, and timely e-verification are equally important for smooth processing and timely refunds.
Taxpayers should avoid rushing the filing process and instead focus on proper compliance, document verification, and correct reporting to reduce future notice and penalty risks.
