Understanding Section 148 Notice of Income Tax

Introduction

A notice under Section 148 of the Income Tax Act, 1961 is one of the most serious communications a taxpayer can receive. It relates to reassessment proceedings initiated when the Assessing Officer believes that income has escaped assessment.

Receiving a Section 148 notice does not automatically mean tax liability; it means the department intends to reassess your case based on specific information. With recent landmark jurisprudence regarding the jurisdiction of Jurisdictional Assessing Officers (JAOs) versus Faceless Assessing Officers (FAOs), the retrospective insertion of Section 147A, and the Supreme Court's September 2026 interim stay order, understanding the jurisdictional validity of your notice is now just as critical as analyzing the merits of escaped income.

Key Takeaways

• Section 148 is governed by strict limitation periods and a mandatory Section 148A process.
• Validity checks must include verifying whether the notice was issued by a local JAO or through the automated faceless mechanism under Section 151A.
• The Punjab & Haryana High Court in Jyoti Sareen struck down Section 147A as unconstitutional, and while the Supreme Court granted an interim stay on September 18, 2026, it also ordered an interim stay on all reassessment proceedings until December 3, 2026.
• A timely, evidence-backed reply preserving legal objections can prevent adverse reassessment outcomes.

1. What is Section 148?

Section 148 empowers the Income Tax Department to reopen completed assessments if it has "information" suggesting that taxable income has escaped assessment.

However, post Finance Act 2021 amendments, reassessment proceedings must follow a structured process under Section 148A before a formal notice can be issued.

The Section 148A Procedure:

1. Verification/Enquiry: The department must conduct an enquiry (if required) regarding the information.
2. Show-Cause Notice: Provide the taxpayer an opportunity of being heard through a notice under Section 148A(b).
3. Final Order: Pass an order under Section 148A(d) deciding whether it is a fit case to issue notice under Section 148.
4. The Notice: Only after the above steps are completed can a formal Section 148 notice be issued.

2. When Can a Notice Be Issued?

A notice under Section 148 can be issued if the Assessing Officer has verifiable "information" suggesting that income chargeable to tax has escaped assessment. This information may arise from:

• Data flagged in the Annual Information Statement (AIS) or TIS.
• Information from other government agencies (GST, ED, SEBI).
• High-value transactions mismatch or audit objections.
• Search or survey proceedings conducted on the taxpayer or related parties.

Note: A mere "change of opinion" by a new officer without fresh material is not a valid ground for reopening an assessment.

3. Time Limits for Issuance

The limitation period for issuing a Section 148 notice depends on the amount of income believed to have escaped assessment:

The clock starts from the end of the relevant Assessment Year. If these strict conditions are not met, the notice may be legally invalid.

4. The JAO vs. FAO Conflict: Section 147A & Supreme Court Stay

In addition to limitation and merits, the jurisdictional validity of Section 148 notices has become the subject of national constitutional litigation:

The Core Jurisdictional Clash

Under Section 151A of the Act read with the e-Assessment of Income Escaping Assessment Scheme, 2022 (notified on 29.03.2022), the Central Government mandated that the issuance of notice under Section 148 must be carried out through randomized automated allocation in a faceless manner.

A majority of constitutional courts—including the Bombay High Court (Hexaware Technologies, Kairos Properties), Telangana High Court (Kankanala Ravindra Reddy), Punjab & Haryana High Court (Jatinder Singh Bhangu, Jasjit Singh), Rajasthan High Court (Sharda Devi Chhajer), and Madras High Court (TVS Credit Services)—held that the scheme gives exclusive jurisdiction to the Faceless Assessing Officer (FAO), rendering notices issued by local Jurisdictional Assessing Officers (JAOs) invalid and void ab initio.

Legislative Overrule: Retrospective Section 147A

To validate JAO notices involving approximately ₹17 Lakh Crore in potential tax demand, Parliament enacted Section 147A via the Finance Act, 2026 with retrospective effect from 01.04.2021. Section 147A declared that the Assessing Officer for Sections 148 and 148A shall always be deemed to mean an officer other than the National Faceless Assessment Centre.

The P&H High Court Verdict & Supreme Court Stay (September 2026)

1. Section 147A Struck Down (10.09.2026): In Jyoti Sareen v. Union of India (CWP No. 15791-2024), the Punjab and Haryana High Court held Section 147A to be unconstitutional. The Division Bench ruled that the legislature cannot simply reverse judicial decisions without amending Section 151A and the underlying faceless schemes, violating the doctrine of separation of powers.
2. Supreme Court Stay Order (18.09.2026): The Union of India approached the Supreme Court (Diary No. 51222/2024 / SLP (C) No. 000950-2025). A bench comprising Justice J.B. Pardiwala and Justice K. Vinod Chandran stayed the operation of the High Court's striking-down order.
3. Critical Protection for Taxpayers: Crucially, the Supreme Court ordered that assessment and reassessment proceedings pursuant to the impugned Section 148 notices shall NOT proceed further until the final hearing scheduled for December 3, 2026.

5. How to Respond Strategically

Step 1: Check Validity & Jurisdiction

• Verify whether the notice was issued within 3 years (or 10 years for amounts exceeding ₹50 Lakh).
• Check whether the mandatory Section 148A show cause notice and order were issued properly.
• Check Issuing Authority: Determine whether the notice was issued by your local JAO or through the automated faceless allocation system. If issued by a JAO, record a formal jurisdictional objection under Section 151A while noting the Supreme Court's stay on reassessment proceedings.

Step 2: Obtain the "Reasons"

You are entitled to the specific reasons and information based on which the case was reopened. Analyze the basis of the allegation carefully.

Step 3: File a Return Under Protest

A fresh income tax return must be filed in response to the Section 148 notice within the specified time (usually 30 days), explicitly noting that the filing is under protest and subject to jurisdictional challenges.

Step 4: Submit a Detailed Rebuttal

Submit a comprehensive factual rebuttal with bank statements, audited accounts, and reconciliation statements countering the alleged income escape.

Common Mistakes to Avoid

• Ignoring the Notice: Failure to respond can lead to a "Best Judgment Assessment" (Section 144) where the officer calculates your tax unilaterally, often leading to maximum liability and penalties.
• Inconsistent Data: Providing information to the Assessing Officer that contradicts your AIS or previous ITR filings without a valid reconciliation.
• Missing Jurisdictional Objections: Failing to raise the Section 151A automated faceless allocation ground at the preliminary stage, which may be treated as acquiescence.

Practical Impact

Early validity checks, jurisdictional objections under Section 151A, and timely replies can protect taxpayers from adverse reassessment orders and maintain parity pending the Supreme Court's final verdict in December 2026.
