Filing ITR-1 or ITR-2 incorrectly can trigger automatic notices under Section 143(1) of the Income Tax Act. These notices are often issued when discrepancies appear between the filed return and information available with the tax department, such as TDS, advance tax payments, or salary details. Even small errors, omissions, or incorrect form selection can flag a return for review, creating delays and unnecessary follow-ups. Understanding the common pitfalls in ITR filing is crucial for timely compliance and avoiding stress. Using a reliable platform like TaxBuddy ensures accurate reporting, proper form selection, and a smoother filing experience, minimizing the risk of such notices.

Understanding Common Mistakes in ITR-1 Filing

ITR-1, also known as Sahaj, is primarily designed for salaried individuals and pensioners who have straightforward income sources. Despite its simplicity, taxpayers often make recurring mistakes while filing, which can result in notices, delayed refunds, or the need for corrections.


One of the most common issues is incorrect personal details. Errors in PAN, Aadhaar, or even minor discrepancies in the name or date of birth can trigger notices from the Income Tax Department. It is essential to ensure that all personal information matches official records exactly to avoid unnecessary complications.


Mismatch in TDS is another frequent mistake. Taxpayers sometimes report income or TDS incorrectly compared to Form 26AS, the consolidated tax statement provided by the government. Any mismatch can cause delays in refund processing or even lead to scrutiny notices under Section 143(1).


Omitting certain income sources is also a significant concern. Many taxpayers forget to include interest income from savings accounts or fixed deposits, rental income from properties, or capital gains from the sale of assets. Missing these entries can create discrepancies in the total taxable income and may attract penalties.


Finally, calculation errors are surprisingly common even in ITR-1. Mistakes in computing gross total income, deductions, or total tax liability can result in incorrect filings, delays in refunds, or additional verification requests from the tax authorities.


Even seemingly minor errors in ITR-1 can create substantial delays in processing refunds and may necessitate filing revised returns. Careful verification of all details, cross-checking with official statements like Form 26AS, and using updated ITR utilities can significantly reduce the risk of mistakes.


Understanding Common Mistakes in ITR-2 Filing

ITR-2 is used by individuals and HUFs with more complex income sources, such as capital gains, foreign assets, or multiple house properties. Common mistakes include:


  • Incorrect reporting of capital gains: Misreporting sale proceeds, exemptions, or deductions under Sections 54/54F can raise red flags.

  • Foreign income or assets not disclosed: Non-disclosure of foreign income or accounts triggers automatic notices.

  • Incorrect deductions under Chapter VI-A: Misreporting deductions like 80C, 80D, or 80E can lead to mismatches with TDS or bank statements.

  • Errors in reporting multiple properties: Failing to accurately report rental income or self-occupied property details can result in notices.


These errors are often detected automatically by the IT Department's systems, prompting Section 143(1) notices.


Impact of Mistakes on Tax Processing

Errors in ITR-1 or ITR-2 can have significant consequences for taxpayers, affecting both the timing of refunds and overall compliance status. One of the most immediate impacts of errors in these forms is delayed refunds. When there is a mismatch between the data reported in the ITR and the information available with the Income Tax Department, such as Form 26AS or TDS statements, the system may flag the return for manual verification. This verification process can take time, resulting in a delay in refund issuance. Even minor mistakes, such as incorrect PAN numbers, mismatched bank account details, or misreported income, can trigger this delay.


In addition to delays, errors can also attract penalties or interest. Under Sections 234A, 234B, and 234C of the Income Tax Act, under-reported or late-paid taxes accumulate interest, increasing the taxpayer’s financial burden. For example, if tax liability is understated due to incorrect reporting of salary, capital gains, or deductions, the department charges interest on the shortfall until it is rectified.


Repeated or substantial errors further increase the likelihood of scrutiny under Section 143(3). Such assessments can involve detailed verification of financial statements, supporting documents, and other records, placing an additional compliance burden on the taxpayer.


Correct and accurate reporting in ITR-1 and ITR-2 ensures that refunds are processed promptly, penalties and interest are avoided, and the overall compliance process is smoother, reducing unnecessary stress and administrative work for taxpayers.


How Errors Lead to Section 143(1) Notices

Section 143(1) notices are issued primarily due to:


  • Mismatch in TDS credits: Income reported does not match Form 26AS or Form 16.

  • Arithmetic mistakes: Incorrect summation of taxable income, tax calculations, or deductions.

  • Incomplete or inconsistent information: Missing income, deductions, or reporting multiple sources incorrectly.


The notice essentially informs the taxpayer about these discrepancies and either adjusts the refund or requires a response to rectify errors.


Best Practices to Avoid 143(1) Notices

To minimize the risk of receiving a notice under Section 143(1) of the Income Tax Act, it is essential to follow a few key practices.


Start by verifying your TDS credits before filing your ITR. Cross-check the TDS amounts reflected in Form 26AS against the actual income you have earned. This ensures that all tax deductions claimed by your employer, banks, or other entities are correctly accounted for. Any mismatch in TDS credits is one of the primary reasons for notices under Section 143(1), so resolving discrepancies beforehand can save time and hassle.


Next, ensure you are using the correct ITR form for your income sources. For instance, salaried individuals with no other income should use ITR-1, while those with capital gains or business income may need ITR-2 or ITR-3. Filing under the wrong form often triggers automatic notices, so carefully matching your income profile with the applicable form is crucial.


Double-check all your calculations before submission. Confirm that gross income, deductions, exemptions, and taxable income are computed accurately. Errors in calculations, such as misreporting deductions or incorrectly summing income from multiple sources, are commonly flagged during automated assessments.


Maintain organized supporting documents for all income and deductions claimed. This includes Form 16 from employers, bank statements showing interest income, investment proofs for Section 80C deductions, insurance premiums, and medical bills where applicable. Having these documents ready ensures that you can respond promptly if any query arises.


Finally, use reliable tax filing platforms that offer automated checks and validations. These platforms help detect discrepancies, missing information, and calculation errors before submission. By reducing manual errors, such tools significantly lower the chances of receiving 143(1) notices, making the filing process smoother and more secure.


Importance of Correct Form Selection and Reporting

Choosing the correct ITR form is essential for accurate filing:


  • ITR-1 is suitable for simple salaried individuals with minimal deductions.

  • ITR-2 is required for complex income sources like capital gains, multiple properties, or foreign income. Selecting the wrong form or misreporting income/deductions triggers errors, mismatches, and Section 143(1) notices. Accurate reporting ensures seamless processing, faster refunds, and avoids unnecessary scrutiny.

Q2. How can I avoid receiving a Section 143(1) notice?

A Section 143(1) notice typically arises due to mismatched income, TDS credits, or calculation errors. To avoid this, ensure that your ITR is accurately filed, all TDS and tax credits are correctly reflected, and supporting documents are consistent. Using TaxBuddy’s AI-driven system reduces mismatches by cross-verifying TDS, interest, and other income data automatically.


Q3. Which ITR form should I use if I have multiple income sources?

The choice of ITR form depends on your income type. If you have salary, interest, rental income, ITR-2 may be suitable. For business or professional income, ITR-3 or ITR-4 is applicable. TaxBuddy helps identify the correct form based on your income sources, ensuring compliance with the latest Income Tax rules.


Q4. Can incorrect TDS credits trigger a 143(1) notice even if my income is correct?

Yes, mismatched TDS credits are a common reason for Section 143(1) notices. Even if your declared income is accurate, discrepancies between Form 26AS and your ITR can trigger the notice. Filing through TaxBuddy ensures TDS and other credits are automatically reconciled to minimize this risk.


Q5. How long does it take for refunds to be processed after rectifying errors?

Once errors are corrected and the ITR is updated or revised, refunds are generally processed within 30–60 days, depending on the Income Tax Department’s workload and verification process. TaxBuddy helps ensure corrections are filed promptly and accurately to speed up refund processing.


Q6. Are Section 143(1) notices applicable to both ITR-1 and ITR-2 filers?

Yes, Section 143(1) notices can apply to any ITR form, including ITR-1 and ITR-2, if discrepancies are detected in reported income, TDS, or tax paid. The notice is automated and does not depend on the form you filed.


Q7. What documents should I keep ready to respond to a 143(1) notice?

Q11. How can I track my refund status efficiently?

You can track your refund using the Income Tax Department’s e-filing portal, but TaxBuddy simplifies this by providing a dashboard with real-time refund updates, showing status changes and any actions required on your part, saving time and reducing confusion.
