The Post-Finance Act 2021 Regime

The Finance Act, 2021 completely revamped the income tax reassessment framework. Under the new statutory code (Sections 147 through 151), the Assessing Officer can no longer issue a direct reassessment notice without strictly executing the pre-notice inquiry procedure codified under Section 148A and obtaining mandatory statutory sanction under Section 151.

1. Mandatory Procedural Architecture under Section 148A

Section 148A(a) Inquiry The AO conducts a prior inquiry with the approval of specified authority regarding information suggesting escaped income.
Section 148A(b) Notice Mandatory show-cause notice providing assessee between 7 to 30 days to explain why Section 148 notice should not be issued. All adverse material MUST be shared.
Section 148A(d) Order Speaking order deciding whether it is a fit case for reassessment, passed within 1 month from end of month of response.

2. Section 149 Time Limits: 3 Years vs 10 Years

Limitation periods under the new code are strictly defined:

  • Standard 3-Year Window: Notices for any Assessment Year can be issued up to 3 years from the end of the relevant Assessment Year without any minimum monetary threshold.
  • Extended 10-Year Window (§ 149(1)(b)): To reopen beyond 3 years up to 10 years, the AO MUST possess books of account, other documents, or evidence revealing that income escaping assessment amounts to or is likely to amount to ₹50 Lakhs or more represented in the form of an asset, expenditure, or entry.

3. Common Jurisdictional Defects to Challenge

  1. Non-Furnishing of Underlying Material: If the AO fails to supply the actual Insight portal report, investigation wing dossier, or recorded statements alongside the 148A(b) notice, the notice violates principles of natural justice and is liable to be quashed (Delhi High Court in Divya Capital One).
  2. Sanction from Incompetent Authority (§ 151): If the notice is issued after 3 years, sanction MUST be granted by the Principal Chief Commissioner or Principal Director General. Sanction granted by an Additional Commissioner or PCIT for cases beyond 3 years renders the notice invalid.
  3. Below ₹50 Lakh Threshold: Reopening beyond 3 years where the alleged escaped income is even Re. 1 below ₹50 Lakhs is without jurisdiction under Section 149(1)(b).
