The authors examine whether the 2023 amendment to Section 151, aligning sanctioning authorities with Section 149’s extended time limits, applies retrospectively. For reassessment notices issued beyond three years between 2021 and 2023, the Ahmedabad Tribunal deemed the proviso clarificatory, validating sanctions by the Principal Commissioner. Conversely, the Mumbai Tribunal and Bombay High Court ruled the amendment prospective, finding such sanctions invalid without Principal Chief Commissioner approval. They emphasize that Section 149(2) subordinates limitation periods to Section 151’s mandates. Although the Finance Act 2023 resolved this for subsequent notices, earlier cases remain contested.
ISSUE FOR CONSIDERATION
The time limit for issue of notices for reassessment under section 148 are contained in section 149(1) of the Income Tax Act, 1961 (“the Act”). This time limit (as it stood on 1st April 2022) was 3 years from the end of the relevant assessment year, unless an asset, expenditure in respect of a transaction, event or occasion or entry in books of account, of a value of more than Rs.50 lakh, had escaped assessment, in which case the time limit was 10 years from the end of the relevant assessment year.
This time limit stood extended by the third and fourth provisos to section 149(1) (applicable from 1st April 2021 till 1st September 2024), which read as under:
“…Provided also that for the purposes of computing the period of limitation as per this section, the time or extended time allowed to the assessee, as per show-cause notice issued under clause (b) of section 148A or the period during which the proceeding under section 148A is stayed by an order or injunction of any court, shall be excluded:
Provided also that where immediately after the exclusion of the period referred to in the immediately preceding proviso, the period of limitation available to the Assessing Officer for passing an order under clause (d) of section 148A is less than seven days, such remaining period shall be extended to seven days and the period of limitation under this sub-section shall be deemed to be extended accordingly…”
Section 151 of the Act stipulates the authority who is required to grant sanction for issue of notice under section 148. From 1st April 2021 till 31st March 2023, section 151 read as under:
“Specified authority for the purposes of section 148 and section 148A shall be,—
(i) Principal Commissioner or Principal Director or Commissioner or Director, if three years or less than three years have elapsed from the end of the relevant assessment year;
(ii) Principal Chief Commissioner or Principal Director General or Chief Commissioner or Director General, if more than three years have elapsed from the end of the relevant assessment year:”
This section 151 was amended with effect from 1st April 2023, by insertion of a proviso to this section, which read as under:
“Provided that the period of three years for the purposes of Clause (i) shall be computed after taking into account, the period of limitation as excluded by the third, fourth and fifth provisos or extended by the sixth proviso to sub section (1) of Section 149 of the Act.”
An issue has arisen before the Tribunal as to whether the insertion of the above proviso to section 151 with effect from 1st April 2023 is clarificatory in nature and therefore retrospective in operation. In particular, for the period from 1st April 2021 to 31st March 2023, where a notice was issued under section 148 on any date subsequent to the expiry of the relevant time limit of 3 years for issue of such notice (i.e. beyond the period of 3 years), by applying the third or fourth proviso to section 149(1), which was the relevant authority for grant of sanction for issue of notice – the Principal Commissioner of Income Tax (“Pr CIT”) or Principal Chief Commissioner of Income Tax (“Pr CCIT”)? In other words, could there be different time limits for issue of notice and for sanctioning of such a notice? Once the time limit for issue of notice is extended, will it also be extended to the power of the Pr. CIT to sanction such a notice, which otherwise was required to be sanctioned by Pr. CCIT only?

While the Ahmedabad bench of the Tribunal has taken a view that the insertion of the above proviso, extending the date for sanction of issue of notice, is clarificatory in nature and therefore applies retrospectively, and that the sanction by the Pr. CIT in such a case was valid, the Mumbai bench of the Tribunal has held that the proviso operated prospectively, and therefore sanction by the Pr. CIT was invalid in such a case. In other words, the issue is about the authority who should have sanctioned the notice within the extended time; the Pr. CIT or the Pr. CCIT. The amendment by the Finance Act, 2023 seeks to settle this conflict for notices issued and sanctioned on or after 1st April, 2023.
PINKIBEN RIDDHESHKUMAR BHANDARI’S CASE
The issue recently came up before the Ahmedabad Bench of the Tribunal in the case of DCIT vs Pinkiben Riddheshkumar Bhandari, TS-954-ITAT-2026 (AHD).
This was a case pertaining to AY 2018-19, where a notice under section 148A, asking the assessee to show cause as to why proceedings under section 148 should not be initiated, was issued on 11th March 2022, to which the assessee filed a reply on 19th March 2022. A notice under section 148 was subsequently issued on 7th April 2022, after obtaining the approval of the Pr. CIT, alleging that income of Rs.44.19 lakh had escaped assessment.
The reassessment proceedings were completed by making the addition of Rs.44.19 lakh on account of bogus long-term capital gains, based on information obtained from the Insight Portal.
In first appeal, the Commissioner (Appeals) deleted the addition made by the AO both on legal grounds as well as on merits. The Commissioner (Appeals) noted that the income alleged to have escaped assessment was less than Rs.50 lakhs. He observed that as per the provisions of section 149 as in force during the relevant period, no notice under section 148 could have been issued for the relevant assessment year if three years had elapsed from the end of the relevant assessment year, unless the case fell under clause (b). As the case of the assessee was clearly covered under section 149(1)(a), the three years’ time period from the end of the relevant year expired on 31 March 2022. Since the notice was issued on 7 April 2022, the same was held to be time barred by the Commissioner (Appeals).
The Commissioner (Appeals) also noted that no notice under section 148 could be issued without the prior approval of the specified authority. As per the provisions of section 151 as in force during the relevant period, the specified authority for the purpose of section 148 and section 148A was the Pr. CIT if three years or less than three years had elapsed from the end of the relevant assessment year. In other cases, it was the Pr. CCIT where more than three years had elapsed from the end of the relevant assessment year.
The Commissioner (Appeals) observed that the relevant assessment year in this case was AY 2018-19, and the three-year time period had elapsed on 31 March 2022, and also that the notice under section 148 was issued on 7 April 2022 after obtaining the prior approval of the Pr. CIT. Since, as per the provisions of section 151(ii), the competent authority to give approval after the lapse of three years from the end of the relevant assessment year was the Pr. CCIT, therefore the notice issued under section 148 was liable to be quashed.
In further appeal, the Tribunal examined the third and fourth provisos to section 149(1) as they then stood for the relevant period. It observed that these provisos had escaped the attention of the Commissioner (Appeals). The notice under section 148A(b) was issued by the AO on 11 March 2022, and the reply to that was filed by the assessee on 19 March 2022. As per the third proviso to section 149(1), the limitation period stopped running on 11 March 2022 and restarted on 19 March 2022. Further, as per the fourth proviso, if, after exclusion of the time period allowed to the assessee for filing reply to the notice under section 148A(b), the period of limitation available to the AO for passing order under section 148A(d) was less than seven days, the remaining period was extended to seven days. The Tribunal accordingly held that after excluding the time period of eight days from the date of issue of notice under section 148A(b) till the date of filing of reply by the assessee to this notice, the order under section 148A(d) was passed in time and the notice under section 148 had been issued well within the limitation period.
The Tribunal held that, for the purposes of section 151, the limitation period as provided under section 149, including the extended period under the third and fourth provisos for calculating the time period of three years, would also apply. Therefore, in the view of the tribunal, the three years from the end of the relevant year had to be counted as per the provisions of section 149 for obtaining approval of the specified authority.
The Tribunal observed that it would be an implausible, far-fetched and unconvincing interpretation of the relevant provisions of Sections 149 read with Section 151, to interpret that the three years’ limitation period for issuing of notice u/s 148 as prescribed u/s 149 and that for obtaining approval of the specified authority u/s 151, were different. Both the provisions of Sections 149 and 151, as held by the Tribunal, were required to be read in consonance and in harmony with each other as they operated collectively and not in isolation to each other. Therefore, the three-year period from the relevant assessment year for issuing notice under section 148 and for obtaining section under section 151 had to be counted after excluding the extended period as provided under the third and fourth provisos to section 149.
The Tribunal further noted that this anomaly stood removed by the insertion of the proviso to section 151 by the Finance Act, 2023 with effect from 1 April 2023, which read as under:
“… Provided that the period of three years for the purposes of clause (1) shall be computed after taking into account the period of limitation as excluded by the third or fourth or fifth provisos or extended by the sixth proviso to sub-section (1) of section 149.”
The Tribunal was of the view that this proviso was clarificatory in nature, and supported the view taken by it. Merely because this proviso had been inserted with effect from 1 April 2023, in the view of the tribunal, that would not lead to any conclusion that, before such insertion, the provisions of section 151 were to be read on a standalone basis and in isolation from the provisions of section 149. As per the view taken by the tribunal, even before the insertion of the proviso to section 151, the provisions of sections 149 and 151 had to be read together to arrive at a harmonious view. Hence the period of three years could not be different for the purpose of computing limitation for the issuance of notice under section 148 and for obtaining approval of the specified authority under section 151.
The Tribunal therefore decided this issue against the assessee and in favour of the revenue, holding that the sanction by the Pr. CIT (instead of the Pr. CCIT), during the extended period, was valid.
SHABBIR TAHERI’S CASE
The issue had come up earlier before the Mumbai bench of the tribunal in the case of Shabbir Taheri v ITO, ITA No 1574/Mum/2025, adjudicated by the order dated 15 October 2025.
In this case, the AO had issued show cause notice under section 148A(b) on 20 March 2022. In response to this notice, the assessee furnished his reply on 30 March 2022. After considering the reply of the assessee, the AO passed an order under section 148A(d) on 6 April 2022. Simultaneously, the AO issued notice under section 148 on 6 April 2022, proposing to reassess the income for AY 2018-2019, after obtaining the prior approval of the Pr. CIT on the same day.
The issue of sanction by the Pr. CIT was contested in appeal by the assessee but the appeal was dismissed by the Commissioner (Appeals).
Before the Tribunal, it was argued on behalf of the assessee, that after the expiry of three years from the end of the assessment year under dispute, as per section 151(ii), the specified authority who could grant sanction/approval under section 148A and 148 was only the Pr. CCIT. Since the approval/sanction in the case had been obtained from the Pr. CIT, it was invalid. Hence, all actions taken by the AO pursuant to such approval were also invalid.
On behalf of the revenue, reliance was placed upon a decision of the Mumbai bench of the tribunal in the case of Albert Joseph Rosario v ITO, ITA No 1168/Mum/2025, order dated 22nd July 2025. In this case, a view had been taken that the limitation prescribed under section 149(1) for issuance of notice under section 148 would authorise the Pr. CIT to grant sanction for issue of notice as provided under section 151. As per the reasoning of the bench in that decision, applying the provisions contained in third and fourth proviso to section 149(1) as it then stood, the three year period in terms with section 151(i) was to be determined after excluding the time allowed to the assessee as per show cause notice issued under section 148(b); and further additional time of seven days thereafter to the AO to issue the notice under section 148. The Tribunal chose not to follow the ratio of this decision in view of the other decisions referred to by it in the order.
In adjudicating the appeal in the case under consideration, i.e. Shabbir Taheri’s case, the bench, including the Vice-President of the Tribunal, analyzed the provisions relating to reassessment prior to 1 April 2021, and those as amended by the Finance Act, 2021 with effect from 1 April 2021. The Tribunal noted that section 149(2) provided that the limitation prescribed under section 149(1) for issuance of notice shall be subject to the provisions of Section 151. As per the Tribunal, the use of the word ‘shall’ in section 149(2) made it clear that the limitation prescribed u/s. 149 for issuance of notice u/s. 148 was subject to the timeline prescribed u/s. 151. In other words, the limitation prescribed u/s. 149(1) would not override the timeline prescribed for grant of approval by the specified authority u/s. 151.
The Tribunal noted that the specified authority for grant of sanction before expiry of 3 years from the end of the assessment year was the Pr. CIT, while if more than three years had elapsed, the specified authority was the Pr. CCIT. It found it noteworthy that while the third and fourth provisos were added to section 149(1) effective from 1st April 2021, no corresponding amendment was made to section 151. The proviso to section 151 was added only by the Finance Act, 2023 effective from 1st April 2023. Therefore, as per section 151, as it stood prior to the 2023 amendment, the limitation prescribed under clause (i) of section 151 was three years from the end of the relevant assessment year, without the benefit of further extension as under third, fourth or fifth proviso to section 149(1).
Therefore, according to the Tribunal, keeping in view the provision contained under sub section (2) of section 149 (which made the limitation provided u/s. 149(1) subject to the timeline provided u/s. 151) the limitation provided u/s. 149(1) (including the provisos), could not get imported for the purpose of extending the limitation u/s. 151(i), prior to the amendment of section 151 by Finance Act, 2023. That being the case, the timeline for sanction by specified authority fixed u/s. 151 of the Act had to be scrupulously followed.
The Tribunal relied upon the following decisions of the Bombay High Court, where it had been held that the sanctioning authority for notices issued after expiry of three years was the Pr. CCIT and that the proviso to section 151 would not be applicable in such cases:
Vodafone India Limited, WP No 2678 of 2022
Mystique Media Pvt Ltd v ITO, WP(L) No 12562 of 2024
Punrima Jitendra Navsariwala v ITO, WP No 7 of 2024
Agnello Oswin Dias v ACIT 161 taxmann.com 16 (Bom)
The Tribunal also noted that the Mumbai bench of the Tribunal, after considering the Bombay High Court decision in the case of Vodafone India, had considered the identical issue in the following cases, and decided the matter in favour of the assessee:
Davos International Fund v ACIT, ITA No 1190/Mum/2024
Asha P Kedia 174 taxmann.com 99 (Mum)
The Tribunal also observed that sections 149 and 151 had been enacted for different purposes and operated in different situations. While section 149 prescribed limitation for issuance of notice u/s. 148 and 148A, section 151 prescribed the timeline for the specified authority to grant sanction for sections 148 and 148A. It reiterated that in absence of any enabling provision u/s. 151, the third, fourth, fifth or sixth provisos of section 149(1) could not be read into section 151 to authorise the Pr. CIT to grant sanction for issue of notice under section 148 during the extended time limit u/s. 151(i).
The Tribunal therefore set aside the notice under section 148 for want of sanction from the appropriate authority, and therefore quashed the resultant reassessment order.
OBSERVATIONS
At the outset it is relevant to note that the Tribunal, in holding that the sanction by the Pr. CIT for issue of notice u/s 148 in extended time, was valid in cases of both Pinkiben Riddeshkumar Bhandari (supra) as well as Albert Joseph Rosario (supra), the Bombay High Court decisions on the subject, as well as the earlier decision of Mumbai bench of the Tribunal in Davos International Fund’s case (supra), had not been cited nor considered by the Tribunal.
In Vodafone India’s case (supra), the Bombay High Court held as under:
“3. The impugned order and the impugned notice both dated 7% April 2022 state that the Authority that has accorded the sanction is the PCIT, Mumbai 5. The matter pertains to Assessment Year (“AY”) 2018-19 and since the impugned order as well as the notice are issued on 7th April 2022, both have been issued beyond a period of three years. Therefore, the sanctioning authority has to be the PCCIT as provided under Section 151 (ii) of the Act. The proviso to Section 151 has been inserted only with effect from 1 April 2023 and, therefore, shall not be applicable to the matter at hand.
4. In this circumstances, as held by this Court in Siemens Financial Services Private Limited Vs. Deputy Commissioner of Income Tax & Ors.,’ the sanction is invalid and consequently, the impugned order and impugned notice both dated 7th April 2022 under section 148A(d) and 148 of the Act are hereby quashed and set aside.”
In Mystique Media’s case (supra), the Bombay High Court’s order reads as under:
“4. The impugned order and the impugned notice both dated 5th April 2022 state that the Authority that has accorded the sanction is the PCIT, Mumbai. The matter pertains to Assessment Year (“AY”) 2018-2019 and since the impugned order as well as the notice are issued on 5th April 2022, both have been issued beyond a period of three years. Therefore, the sanctioning authority has to be the PCCIT as provided under Section 151(ii) of the Act. The proviso to Section 151 of the Act has been inserted only with effect from 1 April 2023 and, therefore, shall not be applicable to the matter at hand.
5. In the circumstances, as held by this Court in Siemens Financial Services Private Limited Vs. Deputy Commissioner of Income Tax & Ors, the sanction is invalid and consequently, the impugned order and impugned notice both dated 5 April 2022 under Sections 148A(d) and 148 of the Act are hereby quashed and set aside.”
In Purnima Navsariwala’s case (supra), the conclusion of the Bombay High Court is as under:
“4…..The matter pertains to Assessment Year (“AY”) 2018-2019. Since the impugned order as well as the notice are both issued on 7th April 2022, both have been issued beyond a period of three years, therefore, the sanctioning authority has to be the PCCIT as provided under Section 151(iii) of the Act. The proviso to Section 151 of the Act has been inserted only with effect from 1 April 2023 and, therefore, shall not be applicable to the matter at hand.
5. In these circumstances, Mr. Shah submits that as held by this Court in Siemens Financial Services Private Limited v. Deputy Commissioner of Income Tax & Ors, the sanction is invalid. Mr. Rattesar agrees. Consequently, the impugned order passed under Sections 148A(d) of the Act and impugned notice issued under Section 148 of the Act, both dated 7″ April 2022, are hereby quashed and set aside.”
A similar view has been taken by the Bombay High Court in Alag Property Construction Pvt. Ltd. v. ACIT(2025) 179 taxmann.com 578 (Bom) and in Skypak Travels (P.) Ltd. vs. Income-tax Officer [2026] 185 taxmann.com 963 (Bombay). The Court held that where the period of three years from the end of the relevant assessment year has expired, sanction under section 151(i) could not have been accorded by the Principal Commissioner, and such sanction renders the reassessment proceedings void ab initio.
In Davos International Fund’s case (supra), the Tribunal, after considering the ratio of the Bombay High Court decision in the case of Vodafone India (supra), observed as under:
“8….In the decision of the Vodafone Idea (supra), the Hon’ble High Court has given a specific finding that the proviso to section 151 extending the time limit as per the third, fourth or fifth proviso to section 149 is not applicable for AY 2018-19 as the same is inserted only w.e.f. 01.04.2023. When we apply the said ratio to assessee’s case, in our considered view, the claim of the revenue that the period of 3 years expires only on 09.04.2022 is not correct and that revenue cannot take shelter under the proviso to section 151 which came into effect only from 01.04.2023. Accordingly, the notice issued on 04.04.2022 by the AO is issued beyond three years and therefore the approval should have been obtained by the authorities as specified under section 151(ii) Principal Chief Commissioner. As already stated the approval in assessee’s case is obtained from CIT(IT) and therefore we are inclined to agree with the contention of the assessee that the notice under section 148 has been issued without obtaining the approval from the correct authority as specified under section 151. Respectfully following the above decisions of the Hon’ble Bombay High Court we hold that the notice issued by the AO under section 148 without obtaining approval from correct appropriate authority is invalid and the assessment done under section 147 r.w.s. 144(13) of the Act is liable to be quashed.”
A similar view has been taken by the Mumbai bench of the Tribunal, following the decision in the case of Shabbir Taheri (supra), in the cases of Sanjay Shantilal Dave v Asst Unit 186 taxmann.com 138 (Mum), and Shailesh Asalaraj Jain v Pr CIT, 184 taxmann.com 745 (Mum).
Judicial propriety would have required both benches of the Tribunal to follow the ratio of these decisions. Had these decisions been considered, the view taken by the Tribunal in the cases of Pinkiben Riddeshkumar Bhandari (supra) as well as Albert Joseph Rosario (supra) would have been different.
Further, both these decisions did not consider the impact of section 149(2), as considered by the Tribunal in Shabbir Taheri’s case (supra), which states that the limitation prescribed under section 149(1) shall be subject to the provisions of section 151, and that therefore the provisions of section 151 would override that of section 149(1).
Therefore, the view taken by the Mumbai bench of the Tribunal in Shabbir Taheri’s case (supra), is evidently the better view of the matter, that the extension of time limit under the third and fourth provisos to section 149(1) does not apply to section 151 so as to authorise the Pr. CIT to grant sanction for issue of notice under section 148 during the period extended by third and fourth provisos to section 149. Of course, this controversy no longer survives for notices issued on or after 1st April 2023 by the Finance Act 2023, given the insertion of the proviso to section 151 from that date. After the amendment, the issue of notice u/s 148 on or after 1st April, 2023 during the extended period on sanction by the Pr. CIT is valid in law.
