Types of Income Tax Assessment in India — Scrutiny, Best Judgment and Summary Assessment

After a taxpayer files an Income Tax Return, the Income Tax Department can process, verify or scrutinize it through different types of assessments. Understanding the different types of assessment helps taxpayers respond appropriately and exercise their rights. Here is the complete guide to income tax assessments in India.

1. Self-Assessment — Section 140A

Not a department-initiated assessment — it's the taxpayer's own tax computation and payment before filing ITR. After computing total income, deducting TDS credits, and paying the balance tax (self-assessment tax via Challan 280), the taxpayer files the return. Section 140A requires this self-assessment before ITR filing — any shortfall in self-assessment tax attracts interest under Section 234A.

2. Summary Assessment / Intimation — Section 143(1)

The most common type — an automated processing of the ITR by the CPC (Central Processing Centre) in Bengaluru:

• Computer system checks mathematical accuracy, verifies TDS credits, and reconciles ITR data
• Issues an Intimation under Section 143(1) within 9 months of end of the assessment year
• Intimation may show: (a) Refund due, (b) Amount payable (with demand), or (c) No tax demand/refund
• NOT a full scrutiny — no detailed examination of claims
• Taxpayer can respond to demand in 143(1) Intimation through the online portal

3. Scrutiny Assessment — Section 143(3)

A detailed examination of the ITR by a tax officer — triggered when the return is selected for scrutiny (random selection, risk-based criteria, or specific transactions flagged):

• Notice under Section 143(2) is issued within 3 months of filing — the taxpayer must respond
• Followed by detailed queries under Section 142(1)
• Taxpayer submits documentation, explanations, books of accounts
• Officer passes final assessment order under Section 143(3) — confirming return or making additions/disallowances
• Now conducted as Faceless Assessment under Section 144B

4. Best Judgment Assessment — Section 144

If a taxpayer: (i) fails to file ITR, (ii) fails to respond to notice under 142(1), or (iii) fails to comply with audit under 142(2A) — the officer makes a "best judgment assessment" based on available information, estimating the taxpayer's income. Typically higher than actual income — a strong incentive to respond to notices.

5. Reassessment — Section 147/148

If the department has "reason to believe" that income has escaped assessment (undisclosed income, hidden assets), they can reopen a filed assessment by issuing notice under Section 148:

• Time limit: Within 3 years from the end of the relevant assessment year (if income escaped ≤ ₹50 lakh)
• Extended to 10 years in cases of serious fraud/tax evasion with prior sanction of PCCIT
• After notice, taxpayer must file a return, and the matter proceeds as fresh scrutiny

Conclusion

Income tax assessments range from the automated 143(1) intimation to detailed scrutiny and reassessment proceedings — each requiring a specific response strategy.
