ITR Filing FY 2025-26 Checklist: 10 Mistakes to Avoid Before Filing Your Income Tax Return
ITR Filing FY 2025-26 is now underway, and while filing income tax returns online has become faster with pre-filled forms and digital tools, taxpayers should not assume the process is error-free. Even a minor mistake can result in delayed refunds, tax notices, or a defective return. Before submitting your return, it is important to carefully verify every detail, reconcile your tax records, and ensure all income has been reported accurately.
Experts also stress that filing an income tax return is more than just an annual compliance requirement. It is a financial reconciliation exercise that requires careful attention to avoid unnecessary disputes and delays.
Why You Should Review Your ITR Carefully
The Income Tax Department now provides pre-filled return forms using information available through documents such as the Annual Information Statement (AIS) and Form 26AS. While these features simplify the filing process, they do not guarantee complete accuracy.
Taxpayers remain responsible for ensuring that every income source, deduction, and tax payment has been correctly reported. A thorough review before submission can help prevent refund delays, defective returns, and future scrutiny.

Top 10 Mistakes to Avoid During ITR Filing FY 2025-26
1. Selecting the Wrong ITR Form
Choosing an incorrect ITR form is one of the most common filing errors. If the selected form does not match your income sources or residential status, your return may be treated as defective.
For many salaried individuals, the choice is between ITR-1 and ITR-2. Taxpayers with total income exceeding ₹50 lakh must file ITR-2. Similarly, if capital gains are below ₹1.25 lakh and other eligibility conditions are satisfied, ITR-1 can generally be used.
2. Choosing the Wrong Tax Regime
Before filing your return, compare your tax liability under both the old and new tax regimes. Selecting the appropriate regime could significantly reduce your tax outgo.
Those planning to opt for the old tax regime should remember that the choice must be exercised by filing the return within the applicable due date of July 31, 2026. Missing this deadline may affect your ability to choose the old regime, wherever applicable.
3. Trusting Pre-Filled Information Without Verification
Pre-filled returns are meant to assist taxpayers, not replace manual verification.
Always cross-check salary details, interest income, tax deducted at source (TDS), investments, and other financial information before filing. Any missing or incorrect data should be corrected before submission.

Before submitting your return, verify:
Ensuring these details are accurate helps avoid unnecessary processing delays.
5. Skipping Reconciliation of AIS, Form 26AS and Form 16
One of the most important steps before filing is matching the information available in:
Any mismatch between these records and your ITR may trigger notices or delay refund processing.
6. Forgetting to Report All Sources of Income
Many taxpayers mistakenly report only their salary income.
You should disclose every applicable source of income, including:
Income received from multiple employers
Incomplete income reporting can lead to tax demands later.
7. Ignoring Capital Gains
Income earned from selling shares, mutual funds, or property must be reported correctly.
Even if tax has already been deducted at source, capital gains should still be disclosed in the return wherever applicable. Failing to do so can attract scrutiny.
8. Claiming Deductions You Are Not Eligible For
Only claim deductions and exemptions that you genuinely qualify for.
Keep all supporting documents safely, as the Income Tax Department may request proof during verification. Incorrect claims can lead to notices, additional tax liability, and penalties.
9. Not Reporting Foreign Assets or Overseas Income
Resident taxpayers who hold foreign assets or earn income outside India must disclose these details wherever required.
Failure to report overseas assets or foreign income accurately may invite closer examination and financial penalties under tax laws.
10. Forgetting to Verify Your ITR
Submitting the return is not the final step.
Your ITR is considered complete only after it has been successfully e-verified or after the signed ITR-V acknowledgement has been submitted within the prescribed timeline. Without verification, your return may not be treated as valid.
