Income Tax Notice: Scrutiny vs Summary Assessment Differences

The core difference lies in the depth of review. A summary assessment (under Section 143(1)) is a preliminary, computer-driven check of your return for basic errors, mismatches, or arithmetical mistakes. A scrutiny assessment (under Section 143(3)) is a detailed, officer-led examination of your entire return, where the Assessing Officer (AO) can ask for books of accounts, bills, and supporting documents.

In a summary assessment, the Income Tax Department processes your return and sends an intimation if there is a mismatch between your reported income and the data available with them (e.g., from TDS returns, Form 26AS, or AIS). No personal hearing is involved. In a scrutiny assessment, the AO selects your case for a thorough review, typically through a notice under Section 143(2). The AO can examine every claim, deduction, and expense you have reported.

The legal framework is clear: Section 143(1) governs summary assessments, while Section 143(3) governs scrutiny assessments. The selection for scrutiny can be random or based on specific risk parameters set by the Central Board of Direct Taxes (CBDT). For example, cases with large refund claims or high-value transactions are more likely to be selected for scrutiny.

You can identify the type of notice by its section number and the language used. A summary assessment notice is called an "Intimation" under Section 143(1). It is usually sent electronically through the Income Tax e-filing portal and states that your return has been processed with adjustments. The intimation will show the tax demand or refund due after adjustments.

A scrutiny notice is issued under Section 143(2). It will explicitly state that your case has been selected for scrutiny assessment. The notice will ask you to produce evidence in support of your income, deductions, and claims. It will also mention a date for hearing or submission of documents. The notice is typically sent within six months from the end of the financial year in which the return was filed.

If you receive a notice under Section 142(1), it is a general notice calling for information, which can be part of either a summary or scrutiny process. However, a Section 143(2) notice is the definitive marker of a scrutiny assessment. Always check the section number and the subject line of the notice on the e-filing portal.

For a summary assessment intimation under Section 143(1), you have 30 days from the date of receipt to file a rectification request if you disagree with the adjustments. You can do this online through the e-filing portal. If you do not respond, the intimation becomes final, and the tax demand becomes payable. You can also file a revised return within the prescribed time limit (usually before the end of the relevant assessment year or before the completion of assessment, whichever is earlier) to correct errors.

For a scrutiny assessment under Section 143(2), the procedure is more formal. You must respond to the notice within the time specified (usually 15-30 days). The AO will schedule hearings, and you must attend personally or through an authorised representative. You need to produce books of accounts, bills, vouchers, and any other documents requested. The AO can also ask for explanations on specific transactions or claims. The assessment must be completed within nine months from the end of the assessment year in which the return was filed (e.g., for AY 2024-25, by 31 December 2025).

If you fail to respond to a scrutiny notice, the AO can pass an ex-parte assessment order under Section 144, which is generally unfavourable. You can appeal such an order before the Commissioner of Income Tax (Appeals).

A summary assessment notice (Section 143(1) intimation) is triggered by data mismatches. Common reasons include: (a) mismatch between income reported in your return and TDS/TCS data in Form 26AS or AIS; (b) arithmetical errors in your return; (c) incorrect claim of deductions (e.g., claiming Section 80C deduction without supporting investment); (d) mismatch in PAN or other demographic details.

A scrutiny notice (Section 143(2)) is issued for more serious reasons. The CBDT publishes annual guidelines for scrutiny selection. Common triggers include: (a) large refund claims; (b) high-value transactions (e.g., property purchase, stock market trades) that are not fully explained; (c) cases where the return shows a loss but the taxpayer has other income; (d) cases flagged by the Computer Assisted Scrutiny Selection (CASS) system based on risk parameters; (e) specific industry or profession-based selection (e.g., doctors, real estate agents); (f) cases where the taxpayer has claimed exemptions under Section 10 or Section 54.

The key point is that a summary assessment is automated and data-driven, while a scrutiny assessment involves human judgment and detailed examination.

For a summary assessment intimation (Section 143(1)), if you do not respond within 30 days, the intimation becomes final. The tax demand, if any, becomes payable. You can still file a rectification request later, but it may be subject to additional scrutiny. If you do not pay the demand, the department can initiate recovery proceedings, including attachment of bank accounts or salary.

For a scrutiny notice (Section 143(2)), the consequences are more severe. If you do not respond, the AO will pass an ex-parte assessment order under Section 144. This order is typically adverse, disallowing most of your claims and adding a high income. The tax demand can be substantial. You will also face a penalty under Section 271(1)(b) for non-compliance with the notice. The penalty can be up to ₹10,000 for each failure. Additionally, the AO can initiate prosecution proceedings in cases of wilful non-compliance.

In both cases, you have the right to appeal the final order. For a summary assessment, you can file a rectification under Section 154 or an appeal before the CIT(A). For a scrutiny assessment, you must file an appeal before the CIT(A) within 30 days of receiving the assessment order.

If you receive any income tax notice, first identify its type by checking the section number and subject line. For a summary assessment intimation, respond within 30 days through the e-filing portal. For a scrutiny notice, consult a qualified chartered accountant or tax lawyer immediately to prepare your response and represent you before the Assessing Officer.
