Understanding Scrutiny Assessment Under Section 143(3) of Income Tax
Scrutiny Assessment Under Section 143(3): A Complete Guide
Scrutiny assessment under Section 143(3) of the Income Tax Act is an in-depth review conducted by the Assessing Officer (AO) to verify the accuracy of the income, deductions, and claims made in an income tax return. Its objective is to ensure taxpayers are compliant and not underreporting income or overstating losses.
When Does Scrutiny Assessment Apply?
A scrutiny assessment may be initiated in the following cases:
- A return is filed under Section 139, or in response to a notice under Section 142(1).
- The AO deems it necessary to scrutinize the return for accuracy or completeness.
Selection of Cases
Scrutiny cases are chosen through:
- Computer-Assisted Scrutiny Selection (CASS): Based on AI-driven risk criteria.
- Manual Selection: For cases flagged due to specific indicators.
- Compulsory Scrutiny Guidelines: Issued periodically by the Central Board of Direct Taxes (CBDT).
How Is Scrutiny Initiated?
The process begins only when a notice under Section 143(2) is served to the taxpayer. Key points:
-
The notice may require submission of additional documents or a personal hearing.
-
It must be issued within 3 months from the end of the financial year in which the return was filed.
- Example: If the return is filed in June 2025, the 143(2) notice must be issued by 30th September 2025.
-
Notices are issued electronically, and responses are submitted via the Income Tax e-filing portal.
Common Triggers for Scrutiny
Scrutiny may be initiated for various reasons, including:
- Survey or Search Operations (Sections 133A, 132, 132A)
- High-risk ITR-7 filings (charitable institutions claiming exemption without valid registration)
- Recurring high-value disputes in earlier assessments
- Third-party alerts or enforcement data suggesting possible evasion
- Technical mismatches (TDS, income, GST, Form 26AS, AIS, etc.)
Key Documents You May Need
Be prepared with:
- Books of accounts (cash/bank books, ledgers, trial balance)
- Financial statements (Balance Sheet, P&L, audit report)
- Proof of income (Form 16, salary slips, contracts, bank statements)
- Deduction claims (e.g., 80C, 80D, HRA receipts)
- Tax payment evidence (advance tax, TDS certificates, previous ITRs)
- Business records (invoices, GST returns, inventory)
- Digital compliance proof (DSC usage logs, payment acknowledgements)
