1. Overview of Assessment Procedure
Income tax assessment is the process by which the Income Tax Department examines a taxpayer return and determines the correct amount of tax payable. The Income Tax Act, 2025 has a structured assessment procedure under Chapter XVI with multiple types of assessments — from the simple automatic processing of the ITR to detailed scrutiny assessments. Understanding the process helps taxpayers respond correctly and protect their rights.
2. Types of Assessments Under ITA 2025
| Type | Section (ITA 2025) | Description |
|---|
| Self-Assessment | Section 257 | Taxpayer computes and pays tax before filing ITR. No AO involvement initially. |
| Summary Processing (143(1) equivalent) | Section 257A | Automated processing of ITR by CPC — checks arithmetic, TDS mismatch, deduction limits. Issues intimation (refund/demand). |
| Limited Scrutiny | Section 268 | Specific query on one or more limited issues identified by the system. Faceless. |
| Complete Scrutiny | Section 270 | Full examination of all aspects of the ITR. Faceless. Triggered for risk-based or compulsory selection. |
| Best Judgment Assessment | Section 271 | Where taxpayer fails to respond to notices — AO assesses to the best of their judgment. |
| Reassessment | Section 279 | Reopening of completed assessment when escaped income is discovered. 3/5-year limit. |
3. Summary Processing: The Intimation (Section 257A)
After filing an ITR, the Centralised Processing Centre (CPC) processes it automatically and issues an intimation under Section 257A (143(1) equivalent):
- If CPC computation matches ITR: intimation showing nil demand/refund issued
- If CPC finds discrepancy (TDS not matched, deduction above limit): demand intimation issued
- Response: Taxpayer can agree and pay, or disagree and file a rectification request
- Intimation must be issued within 1 year from the end of the assessment year of filing
4. Scrutiny Assessment: Timeline
| Stage | Timeline |
|---|
| Notice for scrutiny | Within 6 months from end of assessment year |
| Opportunity to be heard | Minimum 15 days notice |
| Draft order issued | Minimum 30 days before final order |
| Final assessment order | Within 12 months from end of assessment year (18 months for complex cases) |
| Demand payment | 30 days from date of order |
5. Taxpayer Rights During Assessment
- Right to be heard before any addition is made to income
- Right to request personal hearing (video conference) in faceless assessment
- Right to submit evidence, documentation, and explanations
- Right to request more time to respond (extension of response deadline)
- Right to appeal final assessment order to Commissioner (Appeals) within 30 days
6. Assessment of Search Cases
Search and seizure cases under Section 247 have a different assessment timeline — the AO can assess the searched person and any other person connected to the search for 6 years from the Tax Year in which the search was conducted. Search assessments are not faceless — they are handled by jurisdictional AOs with direct interaction.

❓ Frequently Asked Questions
What are the types of income tax assessments?
Under Chapter XVI of ITA 2025, there are multiple types: Self-assessment (taxpayer pays and files ITR); Summary processing Section 257A (automatic CPC processing — issues intimation with demand/refund); Limited scrutiny Section 268 (specific query on limited issues, faceless); Complete scrutiny Section 270 (full examination, faceless); Best judgment assessment Section 271 (when taxpayer doesn not respond); and Reassessment Section 279 (reopening completed assessment when income escaped).
What is the summary processing intimation?
The Summary Processing intimation under Section 257A is the automated processing of every filed ITR by the Centralised Processing Centre (CPC). It checks for arithmetic errors, verifies TDS credits against Form 26AS, and checks that claimed deductions are within statutory limits. If the CPC computation matches the ITR, a nil-demand intimation is issued. If there is a discrepancy, a demand intimation is issued. The taxpayer can either pay the demand or file a rectification if the demand is wrong.
What are the taxpayer rights during scrutiny assessment?
During scrutiny assessment, taxpayers have: the right to be heard before any income addition; the right to submit documents, evidence, and explanations; the right to request personal hearing (video conference) in faceless proceedings; the right to request extension of response deadlines; and the right to appeal the final order to Commissioner (Appeals) within 30 days. An AO cannot pass an order with additions without giving the taxpayer a meaningful opportunity to respond.
What is the time limit for completing scrutiny assessment?
The AO must complete a scrutiny assessment within 12 months from the end of the assessment year (18 months for complex cases). For example, for Tax Year 2026-27 (Assessment Year 2027-28), the scrutiny assessment must be completed by 31 March 2029 (or September 2029 for complex cases). If the order is not passed within the time limit, the assessment is time-barred and the ITR as filed by the taxpayer is deemed correct.
What happens if I don't respond to a scrutiny notice?
If a taxpayer fails to respond to scrutiny notices and opportunities given by the AO, the AO can pass a best judgment assessment under Section 271 — computing income to the best of their judgment based on available information. This can result in very high additions and demands without the taxpayer input. Non-response to assessment notices is one of the most common and avoidable reasons for large tax demands. Always respond within the deadline.
