Time limits for income tax notices under Sections 143, 148, and 156 determine how long the Income Tax Department can process returns, start scrutiny, reopen assessments, or raise tax demands. These deadlines shape whether a notice is valid or time-barred. Section 143 governs processing and scrutiny assessments, Section 148 deals with reassessments for escaped income, and Section 156 issues payment demands based on earlier orders. Each carries strict statutory timelines to prevent open-ended proceedings. Platforms like TaxBuddy monitor these notice windows, ensuring timely alerts and precise interpretation so taxpayers can respond without missing critical deadlines.

Understanding Time Limits for Income Tax Notices
Time limits for income tax notices determine how long the department can examine a filed return, initiate scrutiny, reopen old assessments, or demand unpaid taxes. These statutory deadlines prevent open-ended proceedings and ensure that assessments stay confined to defined periods. The timelines differ based on whether the department is processing a return, identifying mismatches, reopening an assessment for escaped income, or issuing a tax demand after an order. Each notice—whether under Section 143, 148, or 156—follows a separate schedule that starts from the end of the relevant financial or assessment year. Tracking these dates helps determine whether a notice is valid or time-barred, avoiding unnecessary compliance. Platforms like TaxBuddy simplify this by mapping each notice to the statutory window it belongs to, making timelines easy to follow without technical confusion.
Section 143 Time Limits: Processing and Scrutiny Assessments
Section 143 covers two major processes: return processing under sub-section (1) and scrutiny under sub-section (2). The timelines for each flow from the year in which the return is filed. For Section 143(1), the intimation must be issued within nine months from the end of the financial year when the return was submitted. For example, if a return for FY 2024–25 is filed by July 31, 2025, the outer limit for issuing an intimation ends on December 31, 2026.
For scrutiny, Section 143(2) requires the department to issue the first notice within three months from the end of the financial year in which the return was filed. A return filed by July 31, 2025, can receive a scrutiny notice only till June 30, 2026. The assessment itself must be completed within 12 months from the end of the relevant assessment year. Missing the issuance deadline makes the scrutiny notice invalid, helping taxpayers know when their assessments are conclusively closed.
Key Deadlines Under Section 143(1)
– Intimation must be issued within 9 months from the end of the financial year of filing – Returns for FY 2024–25 filed in 2025 must be processed by December 31, 2026 – Time-barred intimations cannot be acted upon
Scrutiny Notice Timeline Under Section 143(2)
– Notice must be issued within 3 months from end of the financial year of filing – AY 2025–26 scrutiny notices must be issued by June 30, 2026 – Assessment must conclude within 12 months from assessment year-end
How TaxBuddy Tracks Section 143 Notices
TaxBuddy logs the filing date, maps it to statutory deadlines and alerts users if a notice falls outside the permitted window. The system checks whether scrutiny notices meet the three-month issuance rule and whether a 143(1) intimation is still within the valid timeframe. With automatic matching of AIS, TIS, and return data, the platform helps identify mismatches early so scrutiny risk can be addressed proactively.
Section 148 Time Limits: Reassessment and Escaped Income
Reassessment notices under Section 148 are governed by strict limits to prevent reopening past years without cause. The normal time limit allows reassessment up to three years from the end of the relevant assessment year. Older years can be reopened only if escaped income exceeds ₹50 lakhs or involves serious issues such as foreign assets, permitting a 10-year extension.
For example, AY 2023–24 can be reopened under the standard rule until March 31, 2027. High-value cases permit reopening up to March 31, 2034, depending on the assessment year. The assessing officer must also possess information or material suggesting escaped income and cannot issue 148 notices casually. These controls ensure reassessment is evidence-driven rather than speculative.
Standard 3-Year Limit for Section 148
– Reassessment notices permitted within 3 years from end of assessment year – AY 2023–24 reassessment deadline ends March 31, 2027 – Officer must possess valid information indicating escaped income
Extended 10-Year Window for High-Value Cases
– Applies when escaped income exceeds ₹50 lakhs – Includes serious matters like foreign assets and complex financial layers – Cannot be issued beyond 10 years under any circumstance
How TaxBuddy Identifies Section 148 Triggers
TaxBuddy scans AIS, TIS, Form 26AS, broker data, and bank information to identify red flags associated with potential escaped income. The system helps categorize whether the notice falls under the 3-year or 10-year window and checks departmental timelines to determine if the notice is valid or time-barred. Automated reconciliation also reduces the risk of missing discrepancies that could otherwise lead to reassessment.
Section 156 Time Limits: Demand Notices and Payment Deadlines
Section 156 deals with demand notices arising from tax, interest, fees, or penalties determined through an order. Unlike scrutiny and reassessment, Section 156 does not have a direct limit on when the notice may be issued; it depends entirely on the underlying assessment order. However, once issued, a strict 30-day payment rule applies.
Taxpayers must pay within 30 days unless an extended timeline is approved by the assessing officer. Delayed payment attracts interest at 1% per month under Section 220(2), and penalties may apply under Section 221. This section also guides how taxpayers view and respond to demands through the e-filing portal under “Pending Actions”.
Issue Timing for Section 156 Demands
– Issued after an order under Sections 143, 147, 154, etc. – No independent issuance timeline – Validity depends on the order’s chronology
30-Day Payment Rule and Extensions
– Payment due within 30 days of notice – Extensions possible in exceptional cases – Interest and penalties apply for delays
How TaxBuddy Helps in Responding to Demands
TaxBuddy evaluates whether the demand stems from a legitimate assessment order, verifies mismatches, calculates interest exposure, and guides users through online payment or disagreement filings. The platform ensures that deadlines are followed so additional penalties do not accrue unnecessarily.
How TaxBuddy Tracks Sections 143, 148, and 156 Automatically
TaxBuddy’s system synchronizes PAN-linked data with e-filing notices, AIS/TIS information, and order histories. It maps each notice to the corresponding statutory deadline, categorizing them based on urgency and possible escalation. Automated alerts inform users when a notice is approaching a deadline, when additional documents are needed, or when departmental timelines appear incorrect. By analyzing the nature of the notice, the platform identifies if scrutiny is valid, reassessment is permissible, or a demand is prematurely issued.
Common Reasons for Delayed or Time-Barred Notices
– Incorrect mapping of assessment years by the department – Late processing of returns by back-end systems – Reassessment triggered without fresh information – High-volume periods causing procedural delays – Technical issues in the CPC system – Missing jurisdiction transfers causing stalled files
When a notice exceeds statutory deadlines, it becomes time-barred and unenforceable. Identifying such scenarios prevents avoidable compliance efforts.
Steps to Verify Notice Validity Using Timelines
– Check the date of filing the original return – Note the assessment year and map deadlines accordingly – Compare issuance dates against the 143 and 148 statutory windows – Review the order underlying a Section 156 notice – Validate information mismatch through AIS/TIS – Confirm if conditions for extended reassessment apply – Cross-check if the notice is digitally signed within timeline – Use TaxBuddy’s automated validity checker for immediate clarity
Conclusion
Understanding the statutory time limits for Sections 143, 148, and 156 helps avoid unnecessary stress and ensures accurate responses. Each notice carries defined deadlines that decide whether it is valid or time-barred. With automated tracking, expert review, and structured notice categorization, TaxBuddy simplifies the entire process and reduces the risk of missed responses or incorrect interpretations. For anyone looking for assistance in tax filing, it is highly recommended to download the TaxBuddy mobile app for a simplified, secure, and hassle-free experience.
FAQs
Q1. Does TaxBuddy offer both self-filing and expert-assisted plans for ITR filing, or only expert-assisted options?
TaxBuddy provides two distinct filing modes designed to suit different comfort levels. The self-filing option is ideal for users who prefer preparing their returns independently but still want automated data imports, pre-filled figures, mismatch alerts, and smart validation checks. For those who prefer professional oversight, TaxBuddy’s expert-assisted plans assign a qualified tax specialist who reviews documents, corrects discrepancies, prepares the return, and handles submissions. Both options operate on the same secure platform, ensuring compliance with the Income Tax Act and minimizing the chances of errors or notices.
Q2. Which is the best site to file ITR?
A reliable tax-filing platform should offer automation, accuracy, secure data handling, and clear guidance. Platforms like TaxBuddy stand out because they integrate AIS/TIS reconciliation, notice detection, mismatch alerts, and expert support within a simple interface. This reduces manual effort and lowers the risk of errors. While the Income Tax Department’s e-filing portal is the official destination, many individuals choose TaxBuddy for its streamlined workflow, mobile accessibility, and detailed guidance throughout the process.
Q3. Where to file an income tax return?
Income tax returns can be filed directly on the Income Tax Department’s e-filing portal, which is the statutory platform. However, several taxpayers prefer using structured platforms such as TaxBuddy that simplify document imports, categorize income streams, calculate deductions, and verify compliance before submission. After preparing the return on TaxBuddy, the final filing still takes place securely through the department’s system, ensuring full compliance with official requirements.
Q4. Are income tax notice timelines the same for every assessment year?
Time limits for issuing income tax notices vary depending on the section, year of filing, and amendments applicable at that time. For instance, scrutiny timelines under Section 143(2) start from the end of the financial year in which the return was filed, while reassessment limits under Section 148 follow assessment-year-based rules. Finance Act amendments may revise these limits for future years, meaning the timeline for one AY may differ significantly from another. TaxBuddy evaluates each notice against the correct statutory year-specific timeline.
Q5. Can a Section 143(1) intimation be issued after the 9-month timeline?
A Section 143(1) intimation issued after the statutory 9-month window is generally considered time-barred and unenforceable. The system automatically disallows adjustments made through a delayed intimation. However, any previous processing actions taken by the Centralized Processing Centre (CPC) within the timeline remain valid. TaxBuddy helps users identify late intimations by comparing the issuance date with the relevant financial year-end.
Q6. What happens if a Section 148 notice is issued after the 3-year or 10-year limit?
A Section 148 notice issued beyond the permissible limit becomes invalid unless the case qualifies for extraordinary criteria specified under amended Section 149. For standard cases, the limit is three years, while high-value cases may go up to ten. Notices outside these windows cannot be acted upon and are liable to be quashed. TaxBuddy reviews the escaped income category and the department’s timeline to determine whether the notice falls within the legal window.
Q7. How is the time limit for a Section 156 demand calculated?
The Section 156 notice itself does not have an independent issuance timeline. Instead, its validity depends entirely on the underlying order—such as those under Sections 143 or 147. Once issued, the taxpayer must pay the amount within 30 days, unless an extension is granted by the officer. Interest at 1% per month applies for delays. TaxBuddy checks both the order date and notice date to verify whether the demand arises from a valid proceeding.
Q8. Can scrutiny under Section 143(2) continue if the notice was not issued within the 3-month period?
Scrutiny cannot proceed if the original Section 143(2) notice was not issued within the mandatory three-month timeline. The income tax department must issue this notice within that window; otherwise, the proceeding becomes invalid. Any assessment order passed without a valid scrutiny notice is considered defective. TaxBuddy monitors these issuance dates closely, helping users determine whether the scrutiny process was initiated correctly.
Q9. How can a taxpayer confirm whether a notice is time-barred?
A notice can be checked for validity by comparing the issuance date with the statutory timeline applicable to that specific section. For example, Section 143(1) follows a nine-month limit, Section 143(2) follows a three-month limit, and Section 148 follows a three-year or ten-year limit based on escaped income. TaxBuddy automates this verification using recorded filing dates, assessment year logic, and notice timestamps to show instantly whether the notice is valid or time-barred.
Q10. Are delays in issuing notices common due to system errors?
System delays may occur during peak filing seasons or when jurisdiction changes happen between CPC and local officers. However, statutory limits still take precedence. Even if the delay results from back-end processing issues, legally the department cannot exceed the specified timeline. TaxBuddy identifies such inconsistencies when reviewing notices, ensuring taxpayers are aware of potential procedural lapses.
Q11. Does responding late to a valid notice lead to penalties?
Delays in responding to valid notices may result in penalties, interest charges, and escalation to higher proceedings. For instance, missing a 143(2) deadline may lead to best-judgment assessment, while ignoring a 156 demand may attract interest under Section 220(2). TaxBuddy’s alert system helps users avoid missed deadlines by providing continuous updates, reminders, and guided response drafts.
Q12. How does TaxBuddy help manage multiple notices across different sections?
TaxBuddy categorizes every notice based on its section, urgency level, underlying assessment order, and deadline. The platform automatically highlights mismatches and required responses and provides an organized dashboard for tracking each proceeding. With timely alerts and expert review, it ensures that no statutory deadline is missed and helps users handle scrutiny, reassessment, and demand notices smoothly from start to finish.
