1. Based on the facts provided, do not rely solely on the technical ground that the notice under section 148 is invalid. Instead, challenge the reassessment on both jurisdictional and factual grounds.
If the notice under section 148 was issued after 1 April 2021, the Assessing Officer is ordinarily required to follow the procedure under section 148A before issuing a notice under section 148, unless the case falls within one of the statutory exceptions (such as specified search/requisition cases). A reassessment based solely on SFT information relating to purchase of immovable property would, prima facie, not fall within those exceptions. Therefore, if no notice under section 148A(b) and no order under section 148A(d) were issued, the validity of the reassessment can be challenged.
However, first verify the assessment records. It is possible that notices under section 148A were uploaded on the Income-tax portal and treated as electronically served. Download the complete notice history, DIN-wise communications, and assessment records before taking this ground. Also verify the mode of service and whether statutory requirements for service were complied with. The fact that the registered email ID and mobile number had become inactive may support a plea of lack of effective opportunity, but it does not automatically invalidate service if the Department has complied with the prescribed procedure.
Irrespective of the jurisdictional challenge, do not ignore the merits. Explain the complete source of investment in the property with supporting evidence such as bank statements, savings, sale proceeds, loans, gifts, inheritance, or other documentary proof. If the jurisdictional ground fails, a well-supported explanation on merits may still succeed.
Accordingly, the recommended strategy is to:
- Verify whether proceedings under section 148A were actually conducted.
- Challenge the validity of the reassessment if section 148A was not followed (where applicable).
- Simultaneously contest the addition on merits by substantiating the source of investment.
- Raise both jurisdictional and factual grounds in appeal rather than relying exclusively on a procedural defect.
