1. The New Reassessment Regime (Finance Act 2021 onwards)
The Finance Act, 2021 revamped the entire scheme of reassessment under Sections 147 to 151 of the Income-tax Act, 1961. The old concept of 'reason to believe' was substituted with 'information with the Assessing Officer which suggests that the income chargeable to tax has escaped assessment'.
Before issuing a notice under Section 148, the Assessing Officer is statutorily mandated to conduct an inquiry with prior approval under Section 148A(a), serve a show-cause notice under Section 148A(b), consider the reply under Section 148A(c), and pass a speaking order under Section 148A(d).
