Filing your Income Tax Return (ITR) can be a straightforward process if done correctly, but for many taxpayers, navigating the complexities of tax laws can lead to confusion and mistakes. One of the common issues that arises during the filing process is receiving aSection 143(1) notice from the Income Tax Department. This notice is an automatic communication that is sent when there are discrepancies or errors in the tax return submitted. While it’s often associated with self-filing or DIY tax returns, understanding why and how this notice is triggered is key to avoiding potential issues.

What Is a Section 143(1) Notice?
A Section 143(1) notice is a notice sent by the Income Tax Department to a taxpayer after the initial processing of their tax return. This section of the Income Tax Act allows the tax authorities to perform a summary assessment of the return filed, which means they review the return against the tax data provided. The notice can be issued for several reasons, most notably when there are discrepancies or errors in the taxpayer’s return.
The notice typically contains details such as the calculation of the taxpayer’s income, the tax liability, and any discrepancies found during the assessment. The notice also specifies whether the tax refund will be issued or if additional tax payments are required. The tax department issues these notices to ensure that the taxpayer’s information is correct and aligned with the official records, such as TDS (Tax Deducted at Source) and income tax paid.
Why Does DIY Filing Trigger Section 143(1) Notices?
Filing taxes independently, without the guidance of tax professionals, can be convenient for many, but it often leads to errors that may trigger a Section 143(1) notice from the Income Tax Department. Section 143(1) notices are issued for the purpose of preliminary scrutiny of the return. These notices are typically sent when the department identifies discrepancies or errors in a taxpayer’s filed return. For those who opt for Do-It-Yourself (DIY) filing, several common mistakes are often made, leading to such notices. DIY filers may overlook essential details due to lack of experience or knowledge of the complexities of the Income Tax Act, which can result in triggering such notices.
Below are the main reasons whyDIY filing often leads to Section 143(1) notices:
1. Mismatch of TDS Details One of the most common reasons for receiving a Section 143(1) notice is a mismatch in the TDS (Tax Deducted at Source) details reported in the taxpayer’s ITR and the records submitted by employers or other deductors. TDS is typically reflected in Form 26AS, and discrepancies between the TDS amount filed in the return and what is reported in the Form 26AS are often flagged by the Income Tax Department. DIY filers, especially those who are not familiar with the tax reporting process, might fail to cross-check the TDS data fromForm 26ASwith their filed return, leading to such mismatches.
2. Incorrect Income Reporting Another critical reason DIY filers may trigger a Section 143(1) notice is the incorrect reporting of income. Taxpayers may unintentionally omit certain sources of income, report income under the wrong categories, or misclassify income as exempt when it should have been taxed. For example, failing to report interest income from a savings account or omitting capital gains can lead to significant discrepancies in the data, which the Income Tax Department will quickly identify during its processing of the return. Similarly, reporting income under incorrect sections, such as mixing up income from other sources and income from business or profession, can also lead to an automatic notice.
3. Excess or Insufficient Tax Credits DIY filers often claim tax-saving deductions and credits, such as those under Sections 80C, 80D, 80G, and others, but might miscalculate or incorrectly apply them. Incorrect claims of tax credits are a common cause of scrutiny. For instance, many taxpayers fail to verify their actual investment amounts or may claim deductions for expenses that do not qualify under the respective sections. These discrepancies, if not corrected, can result in additional tax liabilities and trigger a Section 143(1) notice. While tax-saving deductions are beneficial, they must be carefully claimed and substantiated with supporting documents, something that DIY filers may overlook.
4. Incorrectly Filed Claims Under Different Tax Regimes A significant change introduced in recent years was the choice between the old and new tax regimes, with different deductions and exemptions available under each. DIY filers, particularly those not familiar with the new tax regime’s details, might inadvertently choose the wrong one or incorrectly calculate their eligibility for certain exemptions. For instance, while the old regime allows for deductions such as HRA (House Rent Allowance) and interest on home loans, the new regime provides lower tax rates but removes many exemptions. Making the wrong choice or miscalculating the claims under either regime can lead to mismatches, and the tax department might issue a Section 143(1) notice to clarify the errors.
5. Missing or Incorrect Details for Exemptions and Deductions Exemptions, such as those under Section 10 (like HRA or Leave Travel Allowance), and deductions under Sections 80C, 80D, and other sections, are often claimed by taxpayers to reduce their taxable income. DIY filers might miss out on necessary documentation to substantiate these claims or enter incorrect details regarding eligible amounts. For example, in the case of Section 80C deductions, if a taxpayer claims deductions for investments in instruments like PPF, LIC premiums, or tax-saving fixed deposits, but fails to provide the necessary proof or enters wrong figures, the tax authorities may issue a notice. Similarly, not providing proper proof for medical expenses or insurance premiums under Section 80D could also trigger a Section 143(1) notice.
6. Errors in the Filing Process Even small errors in the filing process can trigger a Section 143(1) notice. For example, incorrectly filling out certain fields or missing out on mandatory sections in the ITR forms can cause discrepancies between the filed return and the department's records. DIY filers might overlook these technicalities, leading to errors in data entry, which are then flagged by the system. Additionally, there may be issues in the calculation of taxes or the application of rebates, such as the Rebate under Section 87A, leading to incorrect tax liability reporting.
Why DIY Filing Increases the Likelihood of Section 143(1) Notices DIY filing increases the likelihood of triggering a Section 143(1) notice because taxpayers may not fully understand the nuances of tax laws and the filing process. The complexities of the Income Tax Act require attention to detail, and without the expertise of a tax professional, DIY filers often overlook critical aspects that can lead to errors. Professional tax preparers are trained to understand the tax laws, identify potential issues, and file returns accurately. On the other hand, DIY filers, especially those with limited knowledge of the tax code, may make unintentional mistakes that are flagged by the system during the preliminary processing.
While Section 143(1) notices are often routine and meant to verify discrepancies, they can cause stress and delays for DIY filers. They may also lead to the need for further clarifications, potentially prolonging the filing process and delaying refunds.
Real-World Insights from Recent News & Articles
Recent discussions and articles in the media have shed light on how Section 143(1) notices are becoming more prevalent, especially among taxpayers opting for DIY tax filing platforms. The rise of e-filing and online tax portals has made it easier for individuals to file their returns without professional help, but it has also increased the risk of errors. Many of these errors, once detected by the Income Tax Department, lead to the issuance of Section 143(1) notices.
According to a recent article in The Economic Times, a significant portion of taxpayers receiving notices under Section 143(1) are those who filed their returns without professional help. For example, in the case of salaried individuals, many DIY filers report TDS inaccurately or fail to reconcile the amounts correctly with the tax department’s records. This mismatch triggers a notice, which often leads to further complications like delayed refunds or additional tax liabilities.
Additionally, the Indian Express reported that even small errors, such as incorrectly claiming deductions under Section 80C, can trigger notices. These notices are often perceived as a hassle, but they serve as a check to ensure that taxpayers comply with the regulations. However, resolving these issues requires additional paperwork, sometimes leading to delays in the filing process.

Q2: How do I resolve a Section 143(1) notice? To resolve a Section 143(1) notice, you should carefully review the discrepancies mentioned in the notice. If the department has identified errors, correct those errors and, if necessary, file a revised return.

Q3: Is a Section 143(1) notice the same as a tax audit? No, a Section 143(1) notice is not the same as a tax audit.

Failure to respond to the notice within the stipulated period can result in penalties, interest on any unpaid taxes, and further scrutiny of your returns.

You can do this through the Income Tax Department’s e-filing portal, and in some cases, you may need to approach the Commissioner of Income Tax for further resolution.
Q7: Does DIY tax filing increase the chances of a Section 143(1) notice? Yes, filing your taxes independently (DIY) can increase the chances of errors, especially if you're not fully familiar with tax laws and regulations. Incorrectly filled forms, mismatched TDS data, and missing deductions can trigger a Section 143(1) notice. Using professional platforms like TaxBuddy reduces the risk of such errors, as they help guide you through the filing process and offer error-checking features to ensure everything is accurate.
Q8: How long do I have to respond to a Section 143(1) notice? Typically, you have 30 days from the date of receipt of the Section 143(1) notice to respond. The Income Tax Department allows this period for taxpayers to correct any discrepancies and submit supporting documents. If you do not respond within the specified time, further actions, such as additional penalties or delays in processing, could occur.
Q9: Can I revise my return after receiving a Section 143(1) notice? Yes, if you receive a Section 143(1) notice and notice discrepancies in your return, you can file a revised return. This allows you to correct any errors or omissions that triggered the notice, and the revised return will be processed by the Income Tax Department. Filing a revised return ensures that the issues are corrected and helps to avoid any further penalties or legal complications.
Q10: Will a Section 143(1) notice affect my tax refund? Yes, a Section 143(1) notice can affect your tax refund. If discrepancies in your return, such as mismatched TDS credits or incorrect income details, are identified, the processing of your refund may be delayed. In some cases, the refund will only be processed after the discrepancies are resolved, and the necessary corrections are made. Responding promptly and filing a revised return can help ensure that your refund is processed as quickly as possible.
Q11: Can I make corrections in my ITR after receiving a Section 143(1) notice? Yes, you can make corrections to your ITR even after receiving a Section 143(1) notice by filing a revised return. This allows you to address any errors pointed out in the notice, such as mismatches in TDS details or income reporting. Once the revised return is filed, the department will reassess your return, and the refund process can proceed if the issues are resolved.
Q12: Does a Section 143(1) notice mean I will be audited? No, a Section 143(1) notice does not automatically lead to a full tax audit. It is a summary assessment aimed at identifying discrepancies and errors in the filed return. While it can lead to further scrutiny or a tax audit if significant issues are found, the notice itself is just a preliminary check and does not imply an in-depth investigation into your financial records.
