IT Reassessment Notice? 1 Flaw Can Void It

If you get an income tax reassessment notice under Section 148, it must have genuine approval under Section 151 — not a rubber stamp. Courts have thrown out such notices when approval was mechanical, meaning you could legally challenge and win.

Here's what happened: Calcutta High Court quashed an income tax reassessment order and notice because the mandatory Section 151 approval was granted mechanically, without genuine scrutiny of the facts.. Under Indian income tax law, reopening an old assessment under Section 148 requires prior approval from a specified senior authority under Section 151 — this approval must reflect actual application of mind.. The court's ruling means taxpayers can legally challenge reassessment notices if the approval process was a formality rather than a substantive review..

What you should do: Check the date and details on any Section 148 reassessment notice you receive — you typically have 15–30 days to file a reply before the department proceeds.. Ask your tax advisor to verify whether the Section 151 approval accompanying your notice was specific to your case or appears templated and generic — this is a valid legal ground to contest.. File a written objection to the reassessment order before it becomes final; once you pay or accept without objection, courts may treat it as voluntary compliance..

Pro tip: Request a copy of the Section 151 sanction order under RTI or in your reply to the notice — if it is identical wording across multiple taxpayers, that is evidence of mechanical approval and strong grounds to challenge.
