Issue

When are reassessment notices issued after 1 April 2021 within limitation under §149? Practitioners face these key determinations:

  • Elapsed time from AY-end to “issue” date (not service date)
  • Whether alleged escaped income meets the ₹50-lakh threshold
  • Whether escaped income is “represented” in asset/expenditure/entry form
  • Compliance with §148A gateway procedure and approval requirements
  • Applicability of transition provisions and deeming fictions

Rule

Statutory Framework: §149 (Post-2021)

The Finance Act, 2021 fundamentally restructured the reassessment regime by substituting Sections 147, 148, 149, and 151 with effect from 1 April 2021. The new regime introduces stringent limitation periods and threshold-based gatekeeping mechanisms.[1]

Section 149(1)Income-tax Act, 1961

“149. (1) No notice under section 148 shall be issued for the relevant assessment year,—

(a) if three years have elapsed from the end of the relevant assessment year, unless the case falls under clause (b);

(b) if three years, but not more than ten years, have elapsed from the end of the relevant assessment year, unless the income chargeable to tax which has escaped assessment amounts to or is likely to amount to fifty lakh rupees or morefor that year and such income is represented in the form of an asset orexpenditure in respect of a transaction or in relation to an event or occasionor an entry or entries in the books of account…”

Key elements for §149 limitation analysis

Judicial Guardrails: Key Supreme Court Authorities

The following judgments establish the interpretive framework for §149 limitation — critical for any automated analysis that may form part of legal proceedings.

Union of India v. Ashish Agarwal

2022 SCC OnLine SC 543Supreme Court of India2022

Substituted §149 'reduced the permissible time limit … to three years and only in exceptional cases ten years.' SC deemed old-regime §148 notices (issued after 1-4-2021) as §148A(b) show-cause, preserving all §149 defences for assessees and mandating new-scheme compliance.

R.K. Upadhyaya v. Shanabhai P. Patel

(1987) 3 SCC 96Supreme Court of India1987

'A clear distinction has been made … between 'issue of notice' and 'service of notice' under the 1961 Act.' Limitation under §149 runs to 'issue' — once issued within limitation, jurisdiction vests. Service is a condition precedent to assessment, not to reopening jurisdiction.

J.P. Jani v. Induprasad D. Bhatt

(1969) 72 ITR 595 (SC)Supreme Court of India1969

Transition provisions cannot revive a right to reopen that was already time-barred under the old Act — 'unless express language or necessary implication.' Analogous principle applies to §149 transition provisos.

The Ashish Agarwal Deeming Fiction

The Supreme Court's deeming fiction (old §148 → §148A(b)) is a lifeline for assessees: it preserves all §149 defences under the new scheme and requires AOs to re-commence under §148A with information sharing, reply opportunity, and fresh approval. Any notice issued after 1-4-2021 must comply with the substituted scheme.[1]

Application

Application: Automated Limitation Review Workflow

Here's how jhana Suit operationalises the §149 framework — from document upload to CREAC-structured memo output:

1

Extract AY and AY-End Date

Parse assessment year from notice header; compute AY-end as 31 March of that AY. Example: AY 2017-18 → AY-end = 31-03-2018.

2

Identify Issue Date (Not Service)

Extract “issue” date from postal docket, dispatch log, or portal timestamp — per R.K. Upadhyaya, limitation runs to issue, not service.[3]

3

Compute Elapsed Time

Calculate days/years from AY-end to issue date. Classify as: ≤3 years (general) or >3 and ≤10 years (extended) or >10 years (absolute bar).

4

Test ₹50-Lakh Threshold

If >3 years: extract alleged escaped income quantum from annexures. Test against ₹50,00,000 threshold — must be met for that specific AY (no aggregation across AYs).[2]

5

Classify 'Representation' Type

If threshold met: classify whether escaped income is “represented” as (i) asset, (ii) expenditure re: transaction/event, or (iii) book entry.

6

Verify §148A Gateway Compliance

Check: §148A(b) notice issued? Material/information disclosed? Reply window given? §148A(d) order passed within time? Approvals obtained?[1]

7

Select Applicable Clause & Generate Memo

Output: §149(1)(a) vs §149(1)(b); limitation verdict (within/time-barred); CREAC memo with pinpoint footnotes to each cited paragraph, page, and provision.

Worked Example: Step-by-Step Analysis

Hypothetical Illustration

The following is a fictional example for educational purposes. Actual limitation analysis requires careful review of the specific facts and documents in each case.

Consider a reassessment notice issued on 15 February 2025 for Assessment Year 2019-20 (Financial Year 2018-19), alleging escaped income of ₹48,75,000 on account of unexplained cash credits under Section 68 of the Act.

TIME-BARRED

Elapsed: 4y 10m 15d • Threshold: ₹48.75L < ₹50L • Clause: §149(1)(a) exceeded; §149(1)(b) unavailable

Conclusion: The notice is time-barred. It was issued beyond the 3-year limit under §149(1)(a) but fails to meet the ₹50-lakh threshold required for the extended 10-year period under §149(1)(b). The limitation defence is available to the assessee.

Contrast: A Notice Within Limitation

Now consider a notice issued on 29 March 2024 for AY 2017-18, alleging escaped income of ₹1.10 crore represented in the form of a capital asset acquisition.

Instant §149 Analysis: Elapsed time from AY-end, ₹50-lakh threshold tests, representation classification, and clause selection — all with page-linked citations. Polished memos ready to attach to the client's response. Reviews that once required a team now finish in minutes.

Common Pitfalls in §149 Analysis

Practitioners and assessing officers alike must avoid these common errors in §149 limitation analysis:

Confusing “Issue” vs “Service” Dates

Limitation runs to “issue” (not “service”) of notice. Service is a condition precedent to making the assessment order, not to vesting jurisdiction.[3]

Aggregating Across Assessment Years

The ₹50-lakh threshold must be met for the specific assessment year. Income cannot be aggregated across multiple AYs. Delhi HC has categorically held this in multiple decisions.[2]

Overlooking the “Represented” Requirement

For the extended 10-year period, escaped income must be “represented in the form of an asset, expenditure, or entry in books.” Mere suspicion or conjecture is insufficient — the AO must possess “credible material.”[4]

Assuming Transition Revives Time-Barred Years

Transition provisions cannot revive a right to reopen that was already time-barred under the old Act — J.P. Jani principle. New §149 does not resurrect dead claims.[5]

Ignoring §148A Gateway Compliance

Post-Ashish Agarwal, all notices (including “old” ones deemed as §148A(b)) must comply with the new gateway: information disclosure, opportunity to respond, reasoned §148A(d) order, and proper approvals. Non-compliance is fatal.[1]

§149 Limitation Analysis Checklist

Extract AY from notice header; compute AY-end (31 March of that AY).

Identify “issue” date (not service) from postal docket, dispatch log, or portal timestamp. [3]

Compute elapsed time from AY-end to issue date; classify as ≤3, 3–10, or >10 years.

If >3 years: extract alleged escaped income quantum; test against ₹50L threshold for that specific AY (no aggregation). [2]

If threshold met: classify “representation” type — asset, expenditure, or book entry. [4]

Verify §148A gateway compliance: §148A(b) notice, information disclosure, reply window, §148A(d) order, approvals. [1]

Check transition provisions: new §149 applies; J.P. Jani non-revival principle. [5]

Select applicable clause: §149(1)(a) vs §149(1)(b); record outcome with pinpoint footnotes.

Appendix: Key Statutory & Judicial Excerpts

(2022) SCC OnLine SC 543 (per Shah, J.)Union of India v. Ashish Agarwal

“Substituted section 149 is the provision governing the time limit for issuance of notice under section 148… reduced the permissible time limit … to three yearsand only in exceptional cases ten years. It also provides further additional safeguards…”

¶6.1 (quoting Finance Act, 2021 text)CBDT Instruction 01/2022

“149. (1) No notice under section 148 shall be issued for the relevant assessment year,— (a) if three years have elapsed from the end of the relevant assessment year, unless the case falls under clause (b); (b) if three years, but not more than ten years, have elapsed … unless the income chargeable to tax … amounts to or is likely to amount to Rs. 50 lakh or more…”

(1987) 3 SCC 96R.K. Upadhyaya v. Shanabhai P. Patel

“A clear distinction has been made … between 'issue of notice' and 'service of notice' under the 1961 Act. Section 149 prescribes limitation … Once a notice is issued within the period of limitation, jurisdiction becomes vested … Service … is a condition precedent to making the order of assessment.”

(1969) 72 ITR 595 (SC)J.P. Jani v. Induprasad D. Bhatt

“It is not permissible to construe [transition provisions] as reviving the right … already barred under the old Act … unless express language or necessary implication.”
