Section 148A Reassessment: Time Limits & Valid Notice Rules
A reassessment notice under Section 148A is only valid if it follows strict procedural rules and falls within legal time limits. The 2026 ITAT ruling in Elegance Reality confirms: notices issued after the 3-year or 10-year window has closed are void from inception. Here's how to spot a time-barred notice and respond correctly.

Every ITR season, thousands of Indian taxpayers receive a Section 148A notice—often years after the original return was filed—asking them to explain why their income should not be reassessed. For many, the letter arrives as a shock. A landmark 2026 ITAT ruling has confirmed what tax practitioners have long argued: not all reassessment notices are legally valid. Some are time-barred from the moment they are issued.
What Is Reassessment Under Section 147?
Section 147 of the Income-tax Act, 1961 gives the Assessing Officer (AO) power to reopen a completed assessment if the AO has "reason to believe" that income has "escaped assessment"—income that was not declared or incorrectly computed in the original return. Reassessment is not routine audit; it is a specific legal proceeding triggered by new information or documentary evidence.
The Section 148A Procedural Safeguard (Effective 1 April 2021)
The Finance Act 2021 introduced a mandatory four-step process. Before issuing a formal reassessment notice under Section 148, the AO must now follow Section 148A:
- Show-cause notice: AO issues a notice with a summary of information suggesting escaped income, allowing the taxpayer 7 to 30 days to respond.
- Taxpayer's opportunity: Taxpayer submits documents and explanations.
- Reasoned written order: AO passes an order—with prior approval from specified authority—stating whether reassessment is warranted.
- Section 148 notice: Only after this order is issued, the formal reassessment notice follows.
Any notice under Section 148 issued without completing the Section 148A procedure is invalid on its face.
Key point: The Section 148A process is a mandatory taxpayer protection; a reassessment notice issued without it is void ab initio.
Time Limits: When Can the Department Reopen? (Section 149)
Section 149 of the Income-tax Act, 1961 (as substituted by Finance Act 2021) imposes strict time limits based on the amount of alleged escaped income:
The 10-year window is not automatic. It applies only where the AO possesses documentary evidence establishing escaped income of ₹50 lakh or more from specific sources (search/survey findings, intelligence agency input, or foreign tax authority communication).
Practical Example: Priya, a Delhi-based professional, received a Section 148A notice in August 2026 for Assessment Year 2020-21. The alleged escaped income is ₹18 lakh. The end of AY 2020-21 was 31 March 2021. The 3-year time window (applicable since escaped income is below ₹50 lakh) expired on 31 March 2024. The notice issued in August 2026 is time-barred and legally untenable. Priya's response should lead with this limitation objection.
The ITAT's 2026 Confirmation: Elegance Reality vs ACIT
In Elegance Reality vs ACIT (Ahmedabad ITAT, 2026 Taxscan (ITAT) 269), the Ahmedabad bench of the Income Tax Appellate Tribunal quashed a reassessment notice issued after 1 April 2021 for Assessment Year 2015-16. The alleged escaped income fell below ₹50 lakh, so only the 3-year window under Section 149(1)(a) applied. That window had expired long before the notice was issued.
The tribunal held the notice void ab initio—meaning it had no legal existence from the moment of issue. This ruling signals that tribunals are strictly enforcing the Finance Act 2021 time-limit reform. A notice that does not satisfy the ₹50 lakh jurisdictional threshold for the 10-year window cannot survive legal challenge simply because time has run out.
What Happens After a Section 148A Order?
If the AO passes an order under Section 148A concluding that reassessment is warranted, a formal Section 148 notice is issued requiring you to file a return for that Assessment Year. After you file, the AO assesses the case. If you disagree with the assessment, appeal lies first to the Commissioner of Income-tax (Appeals), and thereafter to the Income Tax Appellate Tribunal.
How to Respond to a Section 148A Notice
- Identify the Assessment Year — calculate the end date of that AY and whether the 3-year or 10-year window has expired from that date.
- Review the alleged escaped income — is it stated as below or above ₹50 lakh?
- Verify procedural compliance — confirm that a proper Section 148A inquiry was completed before any Section 148 notice was issued.
- Respond within the prescribed time — usually 15 to 30 days. Non-response can lead to an ex-parte order against you.
- Address both procedure and time limits — your response must challenge both any procedural defect and, if applicable, assert that the notice is time-barred.
- Engage a Chartered Accountant — Section 148A responses demand precise technical drafting and understanding of case law.

Frequently Asked Questions
What is the time limit for issuing a Section 148 reassessment notice?+
Under Section 149, the time limit depends on the alleged escaped income. If it is below ₹50 lakh, reassessment can only be initiated within 3 years from the end of the relevant Assessment Year. If it is ₹50 lakh or more and the AO holds documentary evidence (from search, survey, intelligence agency, or foreign tax authority), the limit is 10 years from the end of that AY. The Finance Act 2021 (effective 1 April 2021) introduced these strict limits.
Can I ignore a Section 148A notice if I believe it is time-barred?+
No. Even if you believe the notice is time-barred, you must formally respond and raise the time-limit objection in writing. Silence or non-response can result in an ex-parte order against you. Formally asserting the time-bar defence creates a record for appeal.
What makes a Section 148A notice invalid?+
A Section 148A notice is invalid if the AO issues a formal Section 148 reassessment notice without first completing the four-step Section 148A procedure (show-cause notice, taxpayer response, reasoned written order, and only then Section 148). It is also invalid if issued after the applicable time limit under Section 149 has expired. The 2026 ITAT ruling in Elegance Reality confirms such notices are void ab initio.
What is the difference between a Section 148A notice and a scrutiny notice under Section 143(2)?+
A Section 143(2) scrutiny notice is issued during the original assessment process, typically within 3 months of filing an ITR. A Section 148A notice is part of a reassessment procedure to reopen an already-completed assessment based on reason to believe income has escaped assessment. They are entirely separate processes with different timelines and procedures.
What commonly triggers a reassessment notice?+
Common triggers include AIS (Annual Information Statement) or TIS (Transaction Information System) mismatches, high-value transactions reported by banks and stock brokers, information from foreign tax authorities under FATCA or CRS, survey operations, or data from the Directorate of Intelligence and Criminal Investigation. Simply receiving information is not enough; the AO must follow the Section 148A procedure.
Do I have to file a return if the AO issues a Section 148 notice after a Section 148A order?+
Yes. The Section 148 notice requires you to file a return of income for that Assessment Year within the specified time. After you file, the AO will proceed with the reassessment. You can then challenge the assessment through the appellate process if you disagree.
Can a Section 148A notice be issued for Assessment Years before 1 April 2021?+
Yes. The Section 148A procedure applies to all reassessment proceedings initiated on or after 1 April 2021, regardless of the Assessment Year in question. However, the time limits under Section 149 apply based on when the notice is issued and the end date of that earlier Assessment Year. Courts have held that notices issued after the window expires are time-barred.
What should I do if the AO approves a Section 148 notice despite my Section 148A objection?+
You can challenge the notice at every level: raise a preliminary legal objection before the AO, appeal to the Commissioner of Income-tax (Appeals), and thereafter to the Income Tax Appellate Tribunal. If the notice is time-barred or issued in breach of Section 148A procedure, courts have consistently quashed such notices as void ab initio.
