As the Income Tax Return (ITR) filing season approaches, taxpayers often rush to complete compliance without giving adequate attention to accuracy and completeness. While the online filing process has become relatively convenient, even minor mistakes may result in notices, refund delays, additional tax liability, or defective returns.
Many taxpayers rely entirely on prefilled data or limited documentation, assuming the filing process is straightforward. However, careful review and proper reconciliation remain essential for accurate return filing.
Below are the top five mistakes taxpayers commonly make while filing their Income Tax Return and how these errors can be avoided.
1. Choosing the Wrong ITR Form
Selecting an incorrect ITR form is one of the most common yet significant mistakes made by taxpayers. The Income Tax Department has prescribed different ITR forms based on the nature and source of income, residential status, and other financial disclosures.
Many salaried individuals mistakenly assume that ITR-1 (Sahaj) is applicable in all cases. However, a taxpayer having capital gains, foreign assets, directorship in a company, income from more than one house property, or certain other specified incomes may not be eligible to file ITR-1.
For example, a salaried employee earning salary income but also having capital gains from mutual funds or equity shares may incorrectly file ITR-1 instead of the appropriate form such as ITR-2. Such incorrect filing may result in a defective return notice and unnecessary compliance burden.
Before filing, taxpayers should carefully review the eligibility criteria of the applicable ITR form and ensure that the selected return form aligns with their financial profile.
2. Ignoring Reconciliation of AIS, TIS, and Form 26AS
Another major mistake taxpayers make is relying solely on Form 16 while filing returns and ignoring reconciliation with Annual Information Statement (AIS), Tax Information Statement (TIS), and Form 26AS.
The Income Tax Department now captures a wide range of financial transactions, including:
- Interest earned on savings accounts and fixed deposits
- Dividend income
- Mutual fund redemption transactions
- Share trading transactions
- High-value financial transactions
- Tax deducted at source (TDS) details
Many taxpayers fail to review these records before filing, resulting in omitted income or mismatches between disclosed income and departmental data.
For instance, interest income from fixed deposits or savings bank accounts is often overlooked because it may not appear in Form 16 on account on non-deduction of TDS. Similarly, taxpayers may unintentionally omit stock market transactions or dividend income, assuming small amounts are immaterial.
Such mismatches can increase the possibility of notices, scrutiny, or refund delays. Therefore, reconciliation of AIS, TIS, and Form 26AS should be treated as an essential step before final submission of the return.
3. Selecting the Wrong Tax Regime Without Proper Comparison
With the availability of both the old tax regime and the new tax regime, taxpayers often make the mistake of selecting the default option without performing a comparative tax calculation.
The new tax regime offers lower slab rates but restricts several deductions and exemptions. On the other hand, the old regime allows deductions under various provisions such as Section 80C, Section 80D, House Rent Allowance (HRA), housing loan interest, and others.
Many taxpayers unknowingly opt for a regime that is less beneficial from a tax-saving perspective. This usually happens due to lack of comparison or insufficient understanding of deduction eligibility.
For example, a salaried employee making substantial investments under Section 80C, paying medical insurance premium, and claiming HRA may benefit more under the old regime. Conversely, taxpayers with minimal deductions may find the new regime more advantageous.
A comparative tax calculation under both regimes should always be performed before finalizing the return to ensure optimal tax efficiency.
4. Incorrect Claim of Deductions and Exemptions, Non-Reporting of Exempt Income, and Missing Small Sources of Income
Many taxpayers either overclaim deductions without proper documentation or fail to report income that appears insignificant.
Incorrect deduction claims commonly arise under provisions such as:
- Section 80C investments
- Section 80D medical insurance premium
- House Rent Allowance (HRA) exemption
- Home loan interest deduction
- Education loan interest
At the same time, taxpayers often neglect to disclose exempt income such as Public Provident Fund (PPF) interest, agricultural income (where applicable), or tax-free income, assuming that exempt income does not require reporting.
Another common issue is omission of smaller income sources, including:
- Savings bank interest
- Fixed deposit interest
- Dividend income
- Freelance or side income
- Rental income
Taxpayers frequently ignore these amounts believing them to be immaterial. However, such income often reflects in AIS or departmental records, leading to inconsistencies in return filing.
A comprehensive review of all income sources, deductions, and exemptions is essential to avoid discrepancies and future complications.
5. Not Verifying the Return After Filing
One of the most overlooked mistakes is assuming that ITR filing is complete immediately after submission.
Merely uploading the return does not complete the filing process. The return must also be verified through prescribed methods such as Aadhaar OTP, net banking, bank account validation, or demat account verification within the prescribed time limit.
Failure to e-verify the return may render it invalid, effectively treating the return as not filed at all. This may expose taxpayers to consequences such as late filing fees, loss of certain benefits, and unnecessary procedural complications.
Therefore, taxpayers should always confirm successful verification after filing and preserve acknowledgement records for future reference.
Conclusion
Income Tax Return filing is not merely a compliance exercise but an important financial responsibility requiring accuracy, proper disclosure, and informed decision-making. Small errors such as selecting the wrong ITR form, ignoring AIS reconciliation, choosing an unsuitable tax regime, omitting income, or failing to verify the return may result in refund delays, defective return notices, or additional tax liability.
Taxpayers should approach ITR filing with due care, review all financial information thoroughly, and avoid last-minute filing to ensure a smooth and error-free compliance experience.
