Section 148 Notice — What It Means and How to Respond
A Section 148 notice from the Income Tax Department is not a routine processing communication — it is a formal income tax notice for reassessment. It signals that the Income Tax Department has received specific information suggesting that your income for a past assessment year was not fully declared or was incorrectly assessed. A Section 148 notice under the Income Tax Act, 1961 has serious implications: it initiates the reassessment process under Section 147, requires you to file a return of income for the year under reassessment, and can result in an income tax demand for tax on the escaped income along with interest under Section 234A, 234B, and 234C, and penalty for under-reporting or misreporting of income under Section 270A.
N D Savla & Associates, Chartered Accountants based in Mumbai, has successfully represented individuals, businesses, companies, and trusts in Section 148 reassessment proceedings across all stages — from the mandatory Section 148A preliminary inquiry to the formal reassessment notice, assessment hearings, and appeals before the Commissioner (Appeals) and the Income Tax Appellate Tribunal. We also provide proactive Income Tax Audit support and compliance review that helps clients avoid the triggers that lead to a Section 148 notice in the first place.
A Section 148 notice requires you to file a return of income for the assessment year specified in the notice. The time given — typically shown in the notice itself — must be strictly adhered to. Unlike a Section 143(1)(a) notice which is limited to prima facie adjustments in a recently filed return, a Section 148 reassessment notice can reach back up to 3 years, or in certain cases up to 10 years, into your income tax filing history. The stakes are therefore significantly higher.
Warning: A Section 148 notice is one of the most serious income tax notices an individual or business can receive. Engage a Chartered Accountant immediately. A wrong response — or no response — leads to an ex parte assessment with arbitrary income additions, heavy interest, and penalties.
What Is a Section 148 Notice Under the Income Tax Act?
A Section 148 notice is issued by a jurisdictional Assessing Officer when he has information suggesting that income chargeable to tax has escaped assessment for a particular assessment year. The legal basis for such reassessment comes from Section 147 of the Income Tax Act, 1961, which empowers the Assessing Officer to assess or reassess income that was not taxed in the original assessment — either because it was not disclosed in the income tax return, because the original assessment was based on incorrect information, or because income escaped assessment on account of an omission or failure to file a return.
Unlike a Section 143(2) scrutiny assessment relating to the current filing year, a Section 148 reassessment notice pertains to a past assessment year — the year for which income is believed to have escaped assessment. This year could be 1, 3, or even 10 years in the past, depending on the category of information the Income Tax Department has received. This backward reach makes the Section 148 notice qualitatively different from all other income tax notices.
What Is "Income Escaping Assessment" Under Section 147?
Under Section 147 of the Income Tax Act, income is treated as having escaped assessment when:
- Income chargeable to tax was not assessed at all in the original assessment
- Income was assessed at a figure lower than it should have been
- Excessive loss, deduction, allowance, or relief was claimed and granted in the original assessment
- A tax was not charged on a transaction, investment, or asset that should have been taxed
- Income was assessed under the wrong head or at the wrong rate
Note: Under the new reassessment regime introduced by the Finance Act, 2021, the old standard of "reason to believe" has been replaced by "information suggesting income has escaped assessment" — a more objective, data-driven threshold that ties AO jurisdiction directly to specific information received from verified sources.
The New Reassessment Framework — Section 148A and Section 148
The Finance Act, 2021 completely overhauled the reassessment provisions of the Income Tax Act by introducing Section 148A as a mandatory pre-notice procedure. A Section 148 notice can now only be issued after the Assessing Officer completes the Section 148A process in full. The new framework operates in three sequential stages:
Stage 1 — Information Triggering Section 147
A Section 148 reassessment proceeding can only be initiated if the Assessing Officer has received specific information within the meaning of Explanation 1 to Section 148. The prescribed information sources include: data flagged by the CBDT's Risk Management Strategy, information from a survey under Section 133A, information from a search or seizure under Section 132, income or transaction data in the Annual Information Statement (AIS), information received from foreign tax authorities under double taxation avoidance agreements and tax information exchange agreements (TIEA), information from the Statement of Financial Transactions (SFT) filed by banks, sub-registrars, and other reporting entities, and DGIT Investigation reports. The income tax portal at incometax.gov.in now makes most of this data visible to the taxpayer through the AIS.
Stage 2 — Section 148A Mandatory Preliminary Inquiry
Before issuing a Section 148 notice, the Assessing Officer must now compulsorily complete the following Section 148A procedure:
- Section 148A(a): Conduct a preliminary enquiry with prior approval of a specified authority (Joint Commissioner or higher rank)
- Section 148A(b): Issue a show-cause notice to the taxpayer, providing a minimum of 7 days (extendable to 30 days on taxpayer's request) to respond and explain why reassessment should not be initiated
- Section 148A(c): Consider the taxpayer's reply and evaluate the material available
- Section 148A(d): Pass a speaking order with prior approval of the specified authority, stating whether this is a fit case for issuing a Section 148 notice
Note: The Section 148A(b) show-cause notice stage is your most important opportunity in the entire reassessment process. A well-argued, well-documented response at this stage can result in the Assessing Officer concluding that this is not a fit case for reassessment and dropping the proceedings — before any Section 148 notice is formally issued.
Stage 3 — Section 148 Formal Reassessment Notice
Only after passing the Section 148A(d) order can the Assessing Officer issue the formal Section 148 notice requiring the taxpayer to file a return of income for the relevant assessment year. Once a Section 148 notice is received, the taxpayer must file a return within the time period specified in the notice. The reassessment then proceeds as a fresh assessment under Section 143(3) read with Section 147, with all the procedural requirements of a regular scrutiny assessment applying.
Who Receives a Section 148 Notice from the Income Tax Department?
Any category of taxpayer can receive a Section 148 reassessment notice — provided the Income Tax Department has specific information suggesting income has escaped assessment. In practice, Section 148 notices are concentrated in specific categories of taxpayers and transactions.
Individual Taxpayers and HUFs
Individuals and HUFs most frequently receive Section 148 notices for undisclosed property purchases reported by sub-registrars in SFT, high-value bank deposits not matching declared income, capital gains on property or shares not declared in the income tax return, foreign investments and remittances reported through FATCA/CRS data exchange, and cash transactions during demonetisation (November–December 2016). Our ITR-6 filing and ITR preparation service ensures complete AIS reconciliation before submission to prevent these triggers.
Business Entities, Companies, and LLPs
Business entities receive Section 148 reassessment notices for unexplained cash credits under Section 68, unexplained investments under Section 69, bogus purchase entries or accommodation entries identified through GSTN data cross-referencing, off-books transactions flagged in survey reports under Section 133A, and large-value director loans not properly documented. Our Business Tax Filing service includes complete transactional documentation review to ensure all entries are properly supported before the income tax return is filed.
Trusts and NGOs
Charitable trusts and NGOs receiving Section 148 notices most commonly face queries about corpus donations declared but not properly evidenced, non-permissible application of trust income for non-charitable purposes, foreign contributions received without proper FCRA compliance declared as exempt income, and income accumulations beyond permissible limits under Section 11(2). The Income Tax Department increasingly scrutinises Section 80G-registered trusts through AIS data and FCRA records.
Non-Resident Taxpayers and NRIs
NRIs and foreign companies receive Section 148 reassessment notices with an extended 10-year time limit for income sourced in India but not disclosed — rental income from Indian properties, capital gains on Indian investments, dividend income, or income received through a permanent establishment arrangement. Foreign account information received through FATCA and CRS automatic exchange increasingly drives NRI reassessment notices.
What Information Sources Trigger a Section 148 Reassessment Notice?
Under the new reassessment regime, the Income Tax Department must have specific information before initiating Section 148 proceedings. The most common trigger sources for Section 148 notices today are:
- Annual Information Statement (AIS) — property purchases, securities transactions, high-value bank deposits, mutual fund investments, insurance policies, and foreign remittances reported by financial institutions
- Statement of Financial Transactions (SFT) — filed by banks (deposits > Rs. 10 lakh), sub-registrars (property registrations), stockbrokers, mutual fund houses, and NBFCs
- CBDT Risk Management Strategy (RMS) — algorithmic matching of ITR data with AIS and SFT to flag cases for reassessment
- Search and seizure operations under Section 132 — information discovered about third parties during searches of other taxpayers
- Survey under Section 133A — information gathered about the taxpayer or related business parties
- FATCA and CRS data — foreign financial account information received from partner tax jurisdictions automatically
- DGIT (Investigation) field intelligence reports — tip-offs, verification reports, and field inspection findings
- Other government department data — customs declarations, FEMA remittances, SEBI filings, and MCA incorporation filings
Note: Since AIS now captures data from dozens of financial institution categories, the single most effective way to prevent a Section 148 reassessment notice is to review your AIS data thoroughly before every income tax return filing and ensure every transaction reflected in AIS is correctly accounted for in your return.
Time Limits for Issuing a Section 148 Reassessment Notice
The Finance Act, 2021 significantly tightened the time limits within which the Income Tax Department can issue a Section 148 notice. Understanding these limits is critical because a Section 148 notice issued beyond the applicable time limit is void and can be challenged and quashed:
General Time Limit — 3 Years
A Section 148 notice cannot ordinarily be issued after 3 years have elapsed from the end of the relevant assessment year. For example, for Assessment Year 2021-22 (financial year 2020-21), the general time limit expired on 31 March 2025. Within this 3-year window, the trigger information can be any of the prescribed sources — AIS mismatch, SFT data, RMS flag, survey information, etc.
Extended Time Limit — 10 Years
A Section 148 notice can be issued up to 10 years after the end of the relevant assessment year, but only if two conditions are simultaneously satisfied: (a) the information suggesting escaped assessment comes specifically from a search under Section 132 or a survey under Section 133A (not AIS or SFT alone); AND (b) the income likely to have escaped assessment is Rs. 50 lakh or more for that assessment year. Both conditions must be satisfied — meeting only one is not sufficient for the extended 10-year limit.
Cases Under the Old Regime — Supreme Court Ruling
Thousands of Section 148 notices issued between 1 April 2021 and 30 June 2021 under the old procedure were challenged across the country. In the landmark Supreme Court decision in Union of India v. Ashish Agarwal (2022), the Supreme Court directed that all such notices be treated as show-cause notices under the new Section 148A(b) procedure and handled accordingly. This judgment continues to have relevance for pending reassessment cases from that period.
How Has Section 147–148 Evolved in India? — Historical Background
Pre-2021 Regime — Broad AO Discretion and Frequent Abuse
Under the pre-Finance Act, 2021 regime, a Section 148 reassessment notice could be issued based on a largely subjective "reason to believe" that income had escaped assessment. No mandatory prior approval was required below the Commissioner level for cases less than 4 years old, no show-cause notice was required before issuing the Section 148 notice, time limits were 4 years (income escaped assessment < Rs. 1 lakh) or 6 years (> Rs. 1 lakh), and the courts were flooded with writ petitions challenging arbitrary Section 148 notices. The old regime generated more income tax litigation than almost any other provision.
Finance Act, 2021 — A Landmark Overhaul of Reassessment Law
The Finance Act, 2021 replaced the old reassessment framework entirely. The new regime introduced: mandatory information-based triggers (replacing subjective "reason to believe"), mandatory Section 148A preliminary inquiry procedure, mandatory show-cause notice to the taxpayer before any Section 148 notice, mandatory prior approval by a senior specified authority at every stage, and reduced time limits (3 years general, 10 years only for large cases involving search/survey). This overhaul was the most significant pro-taxpayer reform in Indian reassessment law in decades.
Supreme Court — Ashish Agarwal (2022) and Its Aftermath
The transition from old to new regime was itself contested extensively. The Supreme Court's 2022 judgment in Union of India v. Ashish Agarwal settled the transition by directing that notices issued under the old procedure during the changeover period be treated as Section 148A(b) notices and handled under the new procedure. This judgment protected thousands of taxpayers and established the new framework's primacy. Several High Courts, including Allahabad, Bombay, Delhi, and Gujarat, have since passed additional judgments refining the procedural requirements under Section 148A.
Present — AIS-Driven, Data-Centric Reassessment
Today, the overwhelming majority of Section 148 notices originate from Annual Information Statement (AIS) data mismatches and CBDT Risk Management System flags. The government's integration of banking, sub-registrar, stockbroker, mutual fund, insurance, and foreign institution data into the AIS has made the Income Tax Department's information base far richer than at any earlier point. Proactive AIS review and full income disclosure in every income tax return is the only reliable defence against a Section 148 reassessment notice.
How to Respond to a Section 148 Notice — 7-Step Process
Responding to a Section 148 reassessment notice requires both procedural awareness and substantive preparation. A wrong step at any stage — or inaction — can result in an ex parte assessment with arbitrary income additions, heavy interest, and penalties. Follow this process:
- Identify the Stage of Proceedings. First determine whether you have received a Section 148A(b) show-cause notice (Stage 2 — preliminary inquiry) or the formal Section 148 notice (Stage 3 — reassessment ordered). These are different documents with different time windows. A Section 148A(b) notice provides the best opportunity to prevent the reassessment from proceeding at all. If you have received a formal Section 148 notice, the Section 148A(d) order has already been passed and you must file a return immediately while raising legal objections in parallel.
- Obtain the Trigger Information. Under the new reassessment framework, the taxpayer is entitled to know the specific information that triggered the Section 148 proceedings. Download your Annual Information Statement (AIS) from the income tax portal at incometax.gov.in and compare it with your original income tax return for the reassessment year. Also request the AO to provide copies of all information forming the basis of the reassessment. Understanding the trigger is essential to structuring an accurate and targeted response.
- Gather Documentation for the Reassessment Year. The Section 148 notice pertains to a past assessment year. Retrieve your original income tax return for that year along with all supporting documents — books of accounts, bank statements, investment records, property documents, capital gain calculations, share certificates, fixed deposit receipts, loan documentation, and any evidence of the transactions in question. Thorough documentation at this stage is the foundation of a successful defence in reassessment proceedings.
- Respond to the Section 148A(b) Show-Cause Notice. If you are at the Section 148A(b) stage, file a detailed, documented response within the prescribed time (minimum 7 days — request an extension to 30 days if the matter is complex). Address every point raised in the show-cause notice, demonstrate that the income in question was already declared in your income tax return or is not taxable, and attach all relevant supporting documents. A well-argued Section 148A(b) response can result in the Assessing Officer dropping the proceedings at the Section 148A(d) order stage, saving you the entire reassessment proceeding. Our Scrutiny Assessment team handles all Section 148A responses with the same rigour as a full assessment proceeding.
- Challenge the Section 148A(d) Order if Legally Unsustainable. If the Assessing Officer passes a Section 148A(d) order directing the issuance of a Section 148 notice despite an adequate response, evaluate the legal sustainability of the order. Orders that do not properly address the taxpayer's reply, are based on information that does not qualify as "information suggesting escaped assessment" under Explanation 1 to Section 148, or violate procedural requirements of Section 148A can be challenged by way of writ petition before the respective High Court under Article 226 of the Constitution of India. Many such orders have been quashed by courts across India.
- File Return in Response to the Section 148 Notice. On receiving the formal Section 148 reassessment notice, file a return of income for the relevant assessment year within the time specified. File the return as you believe it to be correct — you are not required to admit to any additional income in this return. Simultaneously, raise formal written objections to the AO about jurisdiction, procedural compliance with Section 148A, the legal validity of the trigger information, and the time limit. The AO must dispose of your objections before proceeding with the reassessment, as held by the Supreme Court in G.K.N. Driveshafts (India) Ltd. v. ITO (2003). Proper TDS Return Filing and TDS reconciliation records should be included where TDS compliance is in question.
- Participate Fully in Reassessment Proceedings and Appeal if Required. Once the AO disposes of your objections and proceeds with reassessment, participate fully in the proceedings under Section 143(3) read with Section 147. Submit detailed written replies to all questionnaires, provide all documentation, and attend all hearings. If the reassessment order is adverse, appeal to the Commissioner (Appeals) under Section 246A within 30 days of the order. N D Savla & Associates provides complete end-to-end representation in Section 148 reassessment proceedings and appeal matters. We also assist growing businesses through our Virtual CFO service in maintaining year-round documentation standards that make the reassessment defence much stronger.
Warning: Never ignore a Section 148A(b) show-cause notice or a Section 148 reassessment notice. Non-response to a Section 148A(b) notice results in a Section 148A(d) order against you without your side being heard. Non-filing of return in response to a Section 148 notice results in an ex parte assessment by the Assessing Officer on best-judgment basis with adverse consequences.
How Section 148 Reassessment Notices Arise Across Different Sectors
Real Estate Buyers and Sellers
Property sellers and buyers are among the most frequent recipients of Section 148 reassessment notices. Sub-registrar data reported in SFT captures all property registrations above prescribed thresholds. Sellers who received sale consideration but declared lower capital gains in their income tax return, or buyers who made purchases at values significantly above their declared income, receive Section 148 notices. Complete documentation of indexed cost of acquisition, cost of improvement, capital gain computation, and exemptions under Sections 54, 54F, and 54EC is essential for a successful response.
High-Value Cash Depositors — Including Demonetisation Cases
Individuals who made high-value cash deposits — particularly during the November–December 2016 demonetisation period — continue to receive Section 148 reassessment notices where their AIS shows deposits not adequately explained in their income tax return. The Income Tax Department treats unexplained cash deposits as income from undisclosed sources under Section 68 of the Income Tax Act. Cash deposit cases require careful documentation of the source of cash — prior withdrawals, loan receipts, agricultural income, or sales proceeds from exempt assets.
Manufacturing Companies with Unexplained Credits
Manufacturing and trading companies receive Section 148 notices for unexplained cash credits under Section 68, bogus purchase entries or accommodation entries identified through GST invoice matching, large-value inter-corporate loans not supported by proper documentation, and high-value director loans treated as deemed dividends under Section 2(22)(e). Companies filing ITR-6 must maintain complete documentation for all entries in their books to defend successfully in reassessment proceedings.
NRIs and Foreign Asset Holders
Non-resident Indians holding foreign assets or receiving foreign income that was not disclosed to the Income Tax Department face Section 148 notices with the extended 10-year time limit. India's exchange of financial account information with 100+ partner jurisdictions under CRS means that foreign bank accounts, investment portfolios, trust beneficiary interests, and insurance policies held abroad are now visible to the Indian Income Tax Department. Proper disclosure of foreign assets in Schedule FA of the income tax return and foreign income in Schedule FSI is essential for NRI taxpayers.

Frequently Asked Questions About Section 148 Reassessment Notices
What is the difference between a Section 148A notice and a Section 148 notice?
Section 148A(b) is the show-cause notice issued at the preliminary inquiry stage — before any reassessment is ordered. It gives the taxpayer an opportunity to demonstrate that there is no escaped income and that a Section 148 notice should not be issued. Section 148 is the formal reassessment notice issued after the Assessing Officer has completed the Section 148A procedure and passed a Section 148A(d) order concluding this is a fit case for reassessment. The Section 148A(b) stage is your best opportunity to prevent reassessment from proceeding at all. Both are income tax notices, but they operate at different stages of the reassessment process.
Can I challenge a Section 148 reassessment notice in court?
Yes. A Section 148 notice can be challenged before the respective High Court by way of a writ petition under Article 226 of the Constitution of India if it is legally infirm — for example, if it is issued beyond the applicable time limit, if the Assessing Officer did not follow the mandatory Section 148A procedure, if the trigger information does not constitute "information suggesting escaped assessment" under Explanation 1 to Section 148, or if the specified authority did not actually apply its mind before granting approval. Many such writ petitions have succeeded. N D Savla & Associates evaluates all legal challenges available before recommending the appropriate response strategy.
What happens if I do not respond to a Section 148 notice?
If you do not file a return of income in response to a Section 148 reassessment notice within the time specified, the Assessing Officer has the authority to pass a best-judgment assessment under Section 144 read with Section 147. A best-judgment assessment is made ex parte — without the benefit of your books of accounts or explanation — resulting in arbitrary income additions based on the AO's best judgment, which is invariably unfavourable to the taxpayer. Additionally, failure to file the return attracts interest under Section 234A and may attract a penalty. Never ignore a Section 148 income tax notice.
What is the time limit for issuing a Section 148 reassessment notice?
Under the Finance Act, 2021 framework, the general time limit for issuing a Section 148 notice is 3 years from the end of the relevant assessment year. An extended time limit of 10 years applies only where: (i) the information suggesting escaped assessment arises from a search under Section 132 or survey under Section 133A; AND (ii) the income likely to have escaped assessment is Rs. 50 lakh or more. A Section 148 notice issued beyond the applicable time limit is without jurisdiction and liable to be quashed by the High Court.
What are the penalties if income is found to have escaped assessment under Section 148?
If the reassessment under Section 148 results in an income addition, the following consequences apply: tax on the additional income at applicable rates; interest under Section 234A (late filing), 234B (advance tax shortfall), and 234C (deferral of advance tax); and penalty for under-reporting or misreporting of income under Section 270A at 50% of the tax on under-reported income, which rises to 200% in cases of misreporting. In cases where the original return was not filed for the reassessment year, an additional penalty under Section 271F may apply. Section 271(1)(c) concealment penalty can also be levied in cases where income is deliberately concealed.
