Income Tax Notice Under Section 148

A notice under Section 148 is issued when the Assessing Officer has information suggesting that income chargeable to tax escaped assessment for a past year, and it requires you to file (or re-file) a return for that year so the assessment can be reopened under Section 147. "Income escaping assessment" means income that was taxable but was never assessed, because no return was filed, income was under-reported, or new information (AIS/TIS, third-party data, a survey) surfaced after the original assessment. Section 147 is the reassessment power; Section 148 is the notice that triggers it. A 148 notice reopens a completed or time-elapsed year, not a routine processing intimation.

Often searched as a notice u/s 148, it is one of several types of income tax notice the department can issue, and it is distinct from the notices you meet inside a normal assessment. The difference between Section 147 and Section 148 is power versus paper: Section 147 authorises the reassessment, and Section 148 is the letter that starts it.

Search cases initiated on or after 1 September 2024 are handled separately, under the block-assessment scheme in Chapter XIV-B, and not under Section 147 or 148.

Section 148 notices are issued when the Assessing Officer holds "information suggesting income has escaped assessment" as statutorily defined in Section 148(3): most commonly risk-management (RMS) flags, an audit objection, information under a tax treaty, faceless-scheme (Section 135A) data, a survey under Section 133A, or a Tribunal/Court direction. In practice the triggers a taxpayer sees are unreported capital gains on a property or share sale, income omitted from a filed return, large cash deposits or high-value transactions flagged by AIS/TIS or Form 26AS, undisclosed interest or foreign income, and information passed on by another agency. The officer cannot reopen on a mere change of opinion: there must be tangible "information" within the defined categories.

Six reasons the department issues a Section 148 notice:

1. Return not filed
2. Income under-reported
3. Unreported capital gains
4. High-value transactions / cash deposits
5. AIS / third-party mismatch
6. Information from another agency / survey

"Information" is a defined term, not the officer's hunch: Section 148(3) lists the categories that qualify, so a bare suspicion or a fresh view of the same facts does not support reopening.

Section 148A requires the Assessing Officer to give you a show-cause opportunity before issuing a Section 148 notice: the officer serves a show-cause notice with the information relied on and asks why a reassessment notice should not be issued, and you reply within the time specified (generally 7 to 30 days). The officer must then consider your reply and pass a reasoned order, under the current law an order under Section 148A(3), with the prior approval of the specified authority (a Joint or Additional Commissioner under Section 151), deciding whether it is a "fit case". Only if it is does the Section 148 notice issue, accompanied by a copy of that order. A convincing 148A reply, showing the income was disclosed, already taxed, or below the threshold, can stop the reassessment before any 148 notice is issued.

The sequence answer engines lift runs in four steps:

Section 148A was inserted by the Finance Act 2021 (with effect from 1 April 2021); the Finance (No.2) Act, 2024 (with effect from 1 September 2024) substituted both Section 148 and Section 148A, moving from the earlier lettered structure to a numbered one in which the show-cause is Section 148A(1) and the reasoned order is Section 148A(3). The 148A procedure is skipped where the officer acts on faceless-scheme (Section 135A) information, but approval of the specified authority is still mandatory. This show-cause is the taxpayer's best chance to kill the reassessment before it starts.

Section 148A(d) order vs Section 148A(3) order: is the order stage still there?

The reasoned order deciding whether it is a "fit case" to reopen still exists, but its label changed. Under the pre-1 September 2024 procedure (Section 148A as inserted by the Finance Act 2021) the officer worked through four lettered limbs:

• 148A(a): inquiry
• 148A(b): show-cause notice
• 148A(c): consider the reply
• 148A(d): order

The Finance (No.2) Act, 2024 substituted Section 148A with effect from 1 September 2024, replacing the lettered limbs with numbered sub-sections: the show-cause is now Section 148A(1) and the reasoned "fit case" order is Section 148A(3), passed with the specified authority's approval. So a "Section 148A(d) order" belongs to the old lettered procedure, which still governs reassessments initiated under it, including the older assessment years (2013-14 to 2017-18) revived by the TOLA extensions, while a notice issued today carries a Section 148A(3) order instead. Either way the order is the reasoned decision to reopen, and where the notice is time-barred or the "information" is legally insufficient, that order and the consequent 148 notice can be challenged, including by writ petition.

Two Supreme Court decisions, Union of India v. Ashish Agarwal (May 2022) and Union of India v. Rajeev Bansal (October 2024), set the framework under which notices for AYs 2013-14 to 2017-18 were revalidated. The year-by-year limitation treatment is covered separately on the dedicated time-limit page.

To reply to a Section 148A show-cause notice, submit a written response through the e-Proceedings tab on the income tax e-filing portal within the period the notice specifies (generally 7 to 30 days), first requesting the information and material the Assessing Officer relied on, then rebutting it point by point with documentary proof. Your reply should establish, wherever true, that the income was already disclosed and taxed, that it is below the Rs 50 lakh threshold for the extended window, that the year is time-barred under Section 149, or that the reopening rests on a mere change of opinion rather than defined "information". In some cases you may still be able to file an updated return (ITR-U) instead of contesting, but that route closes once a 148A show-cause has been served beyond the permitted window, so decide fast. Because a convincing 148A reply is the last stage at which reassessment can be stopped before a Section 148 notice is issued, prepare it with a Chartered Accountant.

Before you reply, check and authenticate the notice online to confirm it is genuine. This is your reply to a notice under Section 148A, and it must contain five things:

1. Ask in writing for the recorded information and material relied on.
2. Give a factual rebuttal backed by documents: bank statements, sale deed and computation, earlier ITR / Form 26AS / AIS reconciliation.
3. Raise the legal grounds: change of opinion, time-bar under Section 149, below the Rs 50 lakh threshold, or absence of "information" as defined in Section 148(3).
4. Request a personal hearing.
5. File the reply and save the acknowledgement.

Keep the two responses separate: the 148A reply aims to stop the reopening, while the later 148 reply files the return within 3 months from the end of the month. For example, a 148A notice served 5 March 2027, 15-day window → reply by 20 March 2027.

A Section 148 notice can be issued within 3 years 3 months from the end of the relevant assessment year, extended to 5 years 3 months where the Assessing Officer has books of account, documents or evidence showing that the income escaping assessment (as an asset, expenditure, transaction or entry) is Rs 50 lakh or more (Section 149(1), as substituted by the Finance (No.2) Act, 2024, effective 1 September 2024). The preceding Section 148A show-cause notice has its own, shorter outer limit under Section 149(2): 3 years normally, or 5 years for the Rs 50 lakh-plus cases. The extra three months on the 148 notice is the statutory allowance for completing the 148A step. A notice issued after the applicable window is time-barred and can be quashed. Separately, a notice under Section 150 (u/s 150) carries no time bar where it gives effect to a finding or direction in an appeal, revision or court order.

Worked example A (normal): Rs 9,00,000 of unreported bank/FD interest for AY 2024-25 (year ended 31 March 2025). The 148A show-cause must issue within 3 years, by 31 March 2028; the Section 148 notice must issue within 3 years 3 months, by 30 June 2028. A 148 notice after 30 June 2028 is time-barred.

Worked example B (Rs 50 lakh or more): Rs 60,00,000 of unreported long-term capital gain on a property sale (an "asset") for AY 2021-22 (year ended 31 March 2022). The 148A show-cause must issue within 5 years, by 31 March 2027; the Section 148 notice within 5 years 3 months, by 30 June 2027. A notice after 30 June 2027 is time-barred.

For AYs 2013-14 to 2017-18 the deadlines were shifted by the TOLA (Taxation and Other Laws Act, 2020) extensions and settled by the Supreme Court in Rajeev Bansal (2024), so a specific old-year notice may be valid or time-barred on its own facts that this general table does not capture; see how far back the department can reopen your assessment. A narrow proviso adds 15 days where search or survey information surfaces after 15 March and the window would otherwise end on 31 March.

To respond to a Section 148 notice, file the return of income the notice asks for within 3 months from the end of the month in which the notice was issued, through the e-Proceedings tab on the income tax e-filing portal. In your response you can also request the recorded reasons and information, dispute the reopening if it is time-barred or based on a mere change of opinion, and place the correct facts on record; a return furnished after the specified period is not treated as a valid return under Section 139. Because reassessment turns on legal questions (the validity of the notice, the sufficiency of the information, and the limitation period), engage a Chartered Accountant before you reply.

The portal steps are short:

1. Log in to the e-filing portal and open Pending Actions → e-Proceedings.
2. Open the Section 148 notice and file the return in the exact manner it specifies.
3. Upload your reply and supporting documents: bank statements, earlier ITRs, and evidence for the income in question.
4. e-verify and save the acknowledgement.

Do not confuse this with the Section 148A show-cause reply: that reply aims to stop the reopening, while the Section 148 response files the return the reassessment now requires. For example, a notice issued 12 March 2027 → return due by 30 June 2027. The full step-by-step walkthrough to respond to the notice on the e-filing portal covers each screen.

A Section 143(2) notice starts a scrutiny of a return already filed, within the normal assessment window (3 months from the end of the financial year in which the return is filed); a Section 148 notice reopens a past year in which income is believed to have escaped assessment, often years after the original assessment closed. Scrutiny examines what you filed; reassessment brings in a year or income that was never properly assessed. A 148 notice must be preceded by the Section 148A show-cause step and satisfy the Section 149 time limits, safeguards that do not apply to a 143(2) scrutiny notice.

The 148 vs 143(2) distinction comes down to four things:

A Section 143(2) scrutiny notice examines a return you filed; a notice under Section 142(1) is an inquiry before assessment; a Section 148 notice reopens a closed year.

If you ignore a Section 148 notice and do not file the return it requires, the Assessing Officer can complete a best-judgment assessment under Section 144, estimating your income (usually unfavourably) on the material available, and can add the escaped income with interest and penalty. Non-compliance can also attract a penalty under Section 271(1)(b) and, in under-reporting or misreporting cases, a penalty under Section 270A, plus prosecution in serious concealment cases. Ignoring the earlier Section 148A show-cause notice simply forfeits your best chance to stop the reopening.

Interest under Sections 234A, 234B and 234C runs on the unpaid tax, and you can still contest the assessment through the appeal ladder, from the Commissioner (Appeals) to the Income Tax Appellate Tribunal. The full consequences of ignoring an income tax notice are set out separately.
