Worked examples

Notice situations in which section 151 does the work, taken from the first line to the last. Each step carries the authority that licenses it.
A s.148 notice for AY 2020-21 arrived in May 2025 alleging Rs 62 lakh escaped Is this notice inside the s.149 window at all, and does the Rs 50 lakh limb actually apply to this year? 7 steps · 11 authorities · s.148, s.149, s.148A, s.151 The department has my exchange data for FY 2023-24 and says my crypto income is a tenth of what it should be Exchange data shows Rs 6.73 crore of receipts against the Rs 11.6 lakh I put in Schedule VDA, and there is now a s.148A show-cause. How do I answer it, and what do I have to concede? 8 steps · 24 authorities · s.148A, s.149, s.115BBH, s.194S The s.148 notice for AY 2021-22 came from our ward officer, not through automated allocation Is a reassessment notice issued by the jurisdictional Assessing Officer rather than the faceless unit still worth challenging? 7 steps · 15 authorities · s.148, s.148A, s.151A, s.144B

"Reason to believe" and the recorded reasons

The reopening is admittedly driven by an audit objection the Assessing Officer himself did not accept. Is that a ground?

Sanction for reopening (section 151)

Who had to approve this reopening, and does a one-line approval count?
