Introduction

Filing your Income Tax Return (ITR) accurately is crucial to avoid penalties and ensure compliance with the tax laws. For the Assessment Year (AY) 2026-27, taxpayers eligible to file ITR-1 must be cautious of common mistakes that could lead to discrepancies or notices from the Income Tax Department.

Eligibility for Filing ITR-1

ITR-1, also known as Sahaj, is designed for individual residents (other than not ordinarily resident) with a total income up to Rs 50 lakh. This form is suitable for those with income from:

• Salary or pension
• One house property (excluding cases where loss is brought forward from previous years)
• Other sources such as interest

It is crucial to note that ITR-1 is not applicable for individuals with income from more than one house property, capital gains, or income from business and profession. For instance, if you own two residential properties, even if one is vacant, you must opt for ITR-2 or ITR-3, depending on other income sources.

Common Mistakes to Avoid

While filing ITR-1, taxpayers often make errors that can lead to notices or penalties. Here are some common mistakes to avoid:

• Incorrect Personal Information: Ensure that your PAN, name, and address are correctly entered. Mismatches can lead to processing delays and potential notices.
• Mismatch in Income Details: Cross-verify your Form 16 and Form 26AS to ensure that the income details match. Discrepancies can trigger notices from the Income Tax Department.
• Not Reporting Exempt Income: Even though certain incomes are exempt, they must be reported in the ITR. For instance, agricultural income exceeding Rs 5,000 needs to be disclosed, as failing to do so could raise red flags.
• Ignoring AIS and TIS: The Annual Information Statement (AIS) and Taxpayer Information Summary (TIS) provide comprehensive details of your financial transactions. Ensure all reported transactions are accounted for in your ITR to avoid discrepancies.
• Skipping Deductions: Ensure you claim all eligible deductions under Section 80C, 80D, etc., to reduce your taxable income. Missing out on these can lead to higher tax liability.

Filing Process and Compliance Steps

Filing ITR-1 can be done online through the Income Tax e-filing portal. Here are the steps:

1. Log in to the e-filing portal using your credentials.
2. Select 'File Income Tax Return' and choose the appropriate assessment year and ITR form.
3. Fill in the required details, ensuring accuracy in income and deduction entries.
4. Validate the form and calculate the tax payable or refund due.
5. Submit the ITR and verify it using Aadhaar OTP, EVC, or by sending a signed ITR-V to CPC, Bengaluru.

Ensure that all steps are completed accurately and within the deadline to avoid any late fees or interest charges.

Consequences of Incorrect Filing

Filing an incorrect ITR can lead to several consequences, including:

• Receiving a notice from the Income Tax Department for discrepancies, which can be both time-consuming and stressful to resolve.
• Paying interest under Section 234A/B/C for delayed or insufficient tax payments, which can increase your financial burden.
• Facing penalties under Section 270A for under-reporting or misreporting of income, which can be substantial and affect your financial standing.

Conclusion and Checklist

To ensure a smooth filing process, follow this checklist:

• Verify all personal and income details against official documents to avoid mismatches.
• Cross-check Form 16, Form 26AS, AIS, and TIS for consistency to prevent discrepancies.
• Report all exempt income and claim eligible deductions to minimize tax liability.
• File by the due date of 31 July 2026 to avoid late fees and interest charges.
• Keep a copy of the filed ITR and acknowledgment for future reference and potential audits.

By adhering to these guidelines, taxpayers can ensure compliance and avoid unnecessary complications during the ITR filing process.
