Section 153B: Time Limit for Search Assessment under Section 153A

Section 153B prescribes the deadline for completing assessment or reassessment under the earlier search-assessment framework of Section 153A, including cases involving another person under Section 153C. Its operation is restricted to searches initiated or requisitions made before 1 April 2021.

1. What is Section 153B of the Income-tax Act, 1961?

Section 153B, headed Time limit for completion of assessment under section 153A, governs the outer time limit for passing orders in qualifying search and requisition cases. It operates notwithstanding the ordinary assessment limitation in Section 153.

Section 132 concerns authorised searches; Section 132A concerns requisition of books, documents or assets; Section 153A governed assessment of the searched person; and Section 153C concerns qualifying material relating to a person other than the searched person. The scope and year-wise reach of each provision depend on the statutory version governing the search.

2. Section 153B(1): Time limits by financial year

The statute introduced a 21-month general period and later shortened it for specified years. The starting point is ordinarily the end of the financial year in which the last search or requisition authorisation was executed, not necessarily the date the search began.

These are the ordinary statutory periods, before any applicable exclusions, extensions, special provisos, court orders or later legislative relaxations. For earlier searches, confirm the precise version in force and the dates of the relevant proceedings.

Special rule for assessment year 2021-22

A specific proviso deals with certain cases in which the last authorisation was executed, or material was handed over under Section 153C, during financial year 2020-21. It prescribed 30 September 2022 for the assessment relating to assessment year 2021-22. This is a historical transitional deadline, not a generally applicable 2026 deadline.

3. Section 153C: Time limit for another person

Where seized or requisitioned material is lawfully handed over to the Assessing Officer of a person other than the searched person, the statute compares the search-related deadline with the additional period measured from the financial year of handover. The later deadline applies under the relevant proviso. The date and documentary proof of handover may therefore be decisive.

4. Section 153B(2): When is an authorisation executed?

• Search: The authorisation is deemed executed on conclusion of the search as recorded in the last panchnama drawn in relation to the person for whom the warrant was issued.
• Requisition: The authorisation is deemed executed when the authorised officer actually receives the books, documents or assets requisitioned under Section 132A.

The last panchnama, requisition receipt, relevant authorisation and financial-year boundary should be checked before calculating limitation.

5. Exclusions and extensions under Section 153B

The Explanation to Section 153B requires exclusion of specified periods when computing limitation. Depending on the facts and statutory version, these include:

• The duration of a court-ordered stay or injunction affecting the assessment.
• Specified periods relating to special audit under Section 142(2A), including certain court challenges.
• The prescribed interval for a reference to the Valuation Officer under Section 142A.
• Time taken to reopen proceedings or afford rehearing under the proviso to Section 129.
• Specified periods connected with historic Settlement Commission proceedings and applications for advance rulings.
• Specified intervals associated with annulment and revival under Section 153A(2).
• Time for international exchange-of-information requests under Sections 90 or 90A, subject to the statutory cap.
• Specified proceedings concerning impermissible avoidance arrangements under Section 144BA.

Where a valid reference to the Transfer Pricing Officer under Section 92CA(1) is made during qualifying proceedings, Section 153B provides for a 12-month extension in the circumstances stated in its provisos. The Explanation also provides minimum remaining periods in certain situations, including a 60-day safeguard after specified exclusions, and special rules for abated Settlement Commission proceedings.

Section 153B(3) preserves the pre-Finance Act, 2016 version for specified earlier orders and proceedings. Historical cases must therefore be assessed under the relevant text rather than automatically under the latest consolidation.

6. Position after 2021 and under the Income-tax Act, 2025

Searches from 1 April 2021

Section 153B(4) states that the section does not apply where the search is initiated under Section 132 or requisition is made under Section 132A on or after 1 April 2021. Such cases fall to be examined under the reassessment or special search regime applicable to their initiation date, including any relevant saving provisions.

Block assessment from 1 September 2024

The Finance (No. 2) Act, 2024 reintroduced a separate Chapter XIV-B block-assessment framework for qualifying searches or requisitions initiated on or after 1 September 2024. Under the 1961 Act, Section 158BE addresses the time limit for completing block assessment; Section 153B is not its substitute.

Income-tax Act, 2025: Section 296

For the new statute effective 1 April 2026, Section 296 deals with the time limit for completion of block assessment under Section 294. As amended by the Finance Act, 2026, its principal rule provides 18 months from the end of the quarter in which the search was initiated or requisition was made, subject to the section's extensions, exclusions and other-person rules. A qualifying transfer-pricing reference may extend the period by 12 months; an exclusion of up to 180 days is provided for the specified handover period. Transitional application must be checked against the commencement and savings provisions.

Unlike the older Section 153B method, the amended Section 296 rule uses the quarter of initiation of search or requisition as its starting reference. The relevant statutory regime must be identified before comparing deadlines.

7. Practical checklist for limitation disputes

• Identify the date the search was initiated or requisition made to determine which regime applies.
• For a legacy Section 153B case, obtain the last panchnama or requisition receipt and establish the financial year of execution.
• Determine whether the case concerns the searched person or another person under Section 153C, and document any handover date.
• Confirm the assessment years covered, including any relevant earlier-year provisions under Section 153A.
• Check all legally supported exclusions, extensions, transfer-pricing references and court orders.
• Compare the resulting limitation date with the actual date of the assessment order and applicable service requirements.
