Receiving a notice under Section 148 of the Income Tax Act is one of the most stressful events for any taxpayer. It means the department wants to reopen your already-completed assessment. But reassessment is not unlimited — there are strict procedural safeguards, and understanding them can be your strongest defense.
The Section 148A Framework
Since the Finance Act 2021 amendments, the AO must follow a four-step process before issuing a Section 148 notice:
- Conduct preliminary inquiry with prior approval from the specified authority
- Issue a show-cause notice providing all information suggesting income escapement (7-30 days reply period)
- Consider the taxpayer's reply
- Pass a reasoned/speaking order deciding whether to proceed
Only after all four steps are completed can the formal Section 148 notice be issued. Any procedural shortcut is a ground for quashing.
Time Limits Under Section 149
- 3 years from end of relevant Assessment Year — general default period
- Up to 5 years — if escaped income is Rs 50 lakh or more AND supported by documentary evidence (assets, expenditures, book entries). Note: the IT Act 2025 has tightened this from the earlier 10-year window under the post-2021 amendments to the 1961 Act
Four Jurisdictional Grounds to Challenge
1. Invalid Notice Format: CBDT has prescribed specific formats for assessment and reassessment notices. Notices deviating from official formats have been quashed by ITAT in multiple cases.
2. Time-Barred Notices: The six-year limitation must be computed carefully, accounting for COVID extensions (March 2020 to June 2021) and the Supreme Court's Ashish Agarwal decision timeline.
3. JAO vs FAO Jurisdiction: The Bombay HC in Hexaware Technologies (May 2024) held that only Faceless Assessing Officers can issue Section 148 notices. The Delhi HC disagrees. This split remains unresolved — use it if you are in Bombay HC jurisdiction.
4. Change of Opinion: The AO cannot reopen assessment by merely reinterpreting facts already examined during original scrutiny. Demand proof of genuinely new information.
Practical Defense Steps
- Stage 148A is critical: A weak reply here limits your options later. Invest time and evidence at the show-cause stage
- Demand full material: Request complete disclosure of all information the AO relied upon — non-supply is a ground for judicial intervention
- Reconcile AIS and TIS: Before filing returns, ensure your Annual Information Statement and Taxpayer Information Summary match your disclosures
- Document high-value transactions: Capital gains, unsecured loans, and large cash transactions are the most common triggers for reassessment
Reassessment is a legitimate power — but it has boundaries. Knowing those boundaries is the difference between compliance and capitulation.

Good practical advice. The demand-full-material step alone has saved multiple cases in my experience.
AIS reconciliation before filing — this is preventive medicine. Wish more professionals did this routinely.
The JAO vs FAO split is the most interesting jurisdictional battle in tax law right now. Waiting for SC to settle it.
Stage 148A being critical — this cannot be stressed enough. I have seen too many casual replies that killed the case later.
The Hexaware ruling is a game changer in Bombay HC jurisdiction. Used it successfully twice already.
