Can AO Open Inquiry Before Finalizing Assessment?

In the complex world of Indian income tax compliance, taxpayers often face uncertainty when dealing with Assessing Officers (AOs). A common question arises: Whether Inquiry can be Opened by Assessment Officer when the Assessment has Not been Finalised? This issue touches on the balance between the AO's investigative powers and the principles of finality in assessments. Understanding this can help businesses and individuals navigate scrutiny effectively.

This blog post delves into the legal framework under the Income Tax Act, 1961, examines key provisions like Sections 147 and 148, and integrates insights from judicial precedents. Note that this is general information and not specific legal advice—consult a tax professional for your situation.

Legal Framework Governing AO Inquiries

Finality of Assessment and Reopening Provisions

Once an assessment is finalized under Section 143(3), it gains finality. The AO cannot casually revisit it. Reopening is permitted only under Sections 147 and 148 if there's reason to believe that income chargeable to tax has escaped assessment. 2015 0 Supreme(Bom) 577

Key conditions include:1. Reason to Believe: The AO must have tangible material indicating escapement of income.2. Time Limits: Beyond four years from the end of the relevant assessment year, the assessee's failure to disclose material facts must be shown. 2015 0 Supreme(Bom) 577

However, inquiries before finalization are standard. The AO can issue notices under Sections 142(1) or 143(2) to gather information during the assessment process. 2018 0 Supreme(Mad) 2948 2010 0 Supreme(Ori) 433

Inquiries During Ongoing Assessments

If the assessment hasn't been finalized, the AO retains broad jurisdiction to conduct inquiries. For instance, The AO can initiate inquiries and re-open assessments if they have reason to believe that income has escaped assessment. This is applicable even if the assessment has not been finalized, provided the AO acts within the legal framework. 1986 0 Supreme(P&H) 398

This ensures thorough scrutiny without violating natural justice principles, as long as the assessee gets opportunities to respond.

The 'Change of Opinion' Doctrine: A Critical Limitation

A pivotal restriction is the prohibition on reopening based on mere change of opinion. It is well settled that, merely on the basis of the change of opinion, an order of assessment which has been finalised cannot be re-opened. 2024 Supreme(Online)(KER) 52668

Courts have consistently held that new information, like audit reports, must form the basis—not a fresh interpretation of existing facts. Reopening assessments under the Income Tax Act cannot be based solely on a change of opinion; substantial new evidence must be presented to justify such actions. 2025 0 Supreme(Cal) 405

In one case, a notice under Section 148 was quashed because it stemmed from previously examined cash transactions dropped for lack of evidence. The court emphasized: The assessment should not be reopened merely on a change of opinion as the earlier decision was based on available evidence and reasonable grounds. 2025 0 Supreme(Cal) 405

Even pre-finalization, inquiries must be purposeful. The Assessing Officer must provide substantial reasons for re-opening an assessment. If the AO lacks sufficient grounds, the re-opening can be challenged. 2018 0 Supreme(Mad) 2948

Role of New Information and Audit Reports

New tangible material can justify action. The AO can use new information, such as audit reports, to justify re-opening assessments. However, this must be based on tangible material and not merely a change of opinion. 2007 0 Supreme(All) 1265 2024 0 Supreme(Ker) 139

For example, in cases involving unexplained bank deposits, courts mandate thorough verification. Tax authorities must conduct thorough inquiries to substantiate claims of unexplained income before imposing penalties. 2025 Supreme(Online)(ITAT) 5585

The AO is directed to call for necessary details from the concerned Branch Manager and carried out a detailed inquiry to ascertain whether it was the assessee who had opened this bank account. Failure to do so leads to remand for de-novo assessment. 2025 Supreme(Online)(ITAT) 5585

Similarly, in revision proceedings under Section 263, inadequate inquiry by the AO cannot justify revision if the Principal Commissioner hasn't conducted necessary checks. The alleged inadequacy of enquiry by the Assessing Officer cannot be used as a basis to revise the assessment. 2025 Supreme(Online)(ITAT) 8007

Procedural Safeguards and Natural Justice

Inquiries must follow due process, especially in faceless assessments under Section 144B. No draft assessment along with show cause notice as required under section 144B(1) and section 144B(7) is given to petitioner... impugned order of assessment passed by respondent under Section 143(3) read with section 144B... are quashed. 2022 0 Supreme(Guj) 1479

Assessees are entitled to personal hearings if variations are proposed. This underscores that even pre-finalization inquiries cannot bypass principles of natural justice.

Post-initiation, proceedings must conclude logically. However, once an inquiry has been initiated by the Assessing Officer, it cannot but result in either the return being accepted... or for an assessment being conducted. Reopening on the same material post-Section 144C proceedings is invalid without new evidence. 2021 0 Supreme(Del) 407

Time Limits and Approvals for Reassessments

For notices under Section 148 beyond four years, higher authority approval is mandatory. Assessment can be re-opened only if the income which has escaped assessment is Rs. 50,000 or more... The central legal point... requirement for approval by higher authorities. 2018 0 Supreme(Del) 373

Courts have quashed notices lacking such sanction, reinforcing procedural rigor.
