Scrutiny, Reassessment & Appeals (CIT(A) & ITAT): What Good Looks Like

PNPC Global Content Team·

Key takeaways

  • Scrutiny under Section 143(3) examines a return for the year it was filed, while reassessment under Sections 147 and 148 reopens a year over escaped income.
  • Reassessment requires a mandatory Section 148A show-cause process before a formal notice and is subject to time limits under Section 149.
  • A notice under Section 143(2) does not imply wrongdoing, since many returns are selected by CASS risk parameters or mandatory criteria.
  • A routine Section 143(1) intimation, a TDS mismatch or a lower or nil TDS certificate application is not a dispute and does not call for an appeal.

Scrutiny, Reassessment & Appeals (CIT(A) & ITAT) — What to Get Right Before You Start

A scrutiny notice, a reassessment reopening, or an adverse assessment order is not a paperwork problem — it is a legal proceeding with strict timelines, a burden of proof that sits on the taxpayer, and real financial exposure if handled poorly. At PNPC Global, we represent individuals, businesses, and NRIs at every stage of the income-tax dispute lifecycle — from the first scrutiny notice under Section 143(2), through reassessment proceedings under the reformed Section 147/148 regime, to appeals before the Commissioner of Income Tax (Appeals) or Joint Commissioner (Appeals), the Income Tax Appellate Tribunal, and briefing counsel for High Court and Supreme Court references. We do not simply respond to notices — we build the factual and legal record from the first hearing with an eye on how it will read at the Tribunal, because that is where most genuinely disputed additions are actually won or lost.

What This Actually Covers

Income-tax scrutiny, reassessment, and appeals form a structured, multi-forum dispute resolution system. ) here as they remain the terminology most taxpayers and practitioners recognise — we confirm the precise corresponding provision of the 2025 Act applicable to your specific assessment year at the time of engagement. Scrutiny assessment under (1961-Act) Section 143(3) is a detailed examination of a filed return — triggered by CASS (Computer Assisted Scrutiny Selection) risk parameters, specific information from another agency, or mandatory selection criteria — culminating in an assessment order that may confirm the returned income or make additions.

Is This Relevant to Your Business?

  • You have received a notice under Section 143(2) intimating that your return has been selected for scrutiny assessment
  • You have received a notice under Section 148 (preceded by a Section 148A show-cause notice) alleging that income has escaped assessment in a prior year
  • An assessment order under Section 143(3) or Section 144 has been passed with additions to your returned income that you believe are factually or legally incorrect
  • You have received an order from the CIT(A)/JCIT(A) that you wish to contest further at the Income Tax Appellate Tribunal

When It Isn't the Right Fit

  • Your return has not yet been filed or you have simply received a routine processing intimation under Section 143(1) with no scrutiny notice — this is standard return processing, not a dispute; see our ITR filing service
  • You have a straightforward TDS mismatch or Form 26AS reconciliation issue with no scrutiny notice issued — this is usually resolved through a rectification request or grievance, not a formal appeal
  • You are seeking a lower or nil TDS deduction certificate under Section 197 for the current year — this is a prospective application, not an appeal of a past order

Common Questions

What is the difference between scrutiny assessment and reassessment?

Scrutiny assessment under Section 143(3) examines a return for the year in which it was filed, within the normal assessment timeline, typically triggered by CASS risk parameters or specific information. Reassessment under Section 147/148 reopens a year for which assessment has already been completed or the normal assessment window has closed, on the belief that income has escaped assessment. Reassessment is a more serious proceeding procedurally — it now requires a mandatory Section 148A show-cause process before a formal notice can even be issued, and it is subject to strict time limits under Section 149.

Does the Income-tax Act, 2025 change how scrutiny, reassessment, and appeals work?

The Income-tax Act, 2025 has replaced the Income-tax Act, 1961 with effect from 1 April 2026. It was enacted primarily as a language-simplification and reorganisation exercise, and it renumbers a large share of provisions, but the government's stated intent was to preserve the substance of existing tax policy rather than overhaul it. On this page we continue to reference the long-familiar 1961-Act section numbers (Section 143, 148, 148A, 246A, 253, 260A, and so on) because that is still the terminology most taxpayers, advisors, and even ongoing proceedings for pre-2026-27 assessment years use and recognise. For any notice or order you actually receive, we identify the precise corresponding provision under the Act as currently in force before advising on strategy or deadlines.

I have received a notice under Section 143(2). Does this mean I have done something wrong?

Not necessarily. A large proportion of scrutiny selections happen through CASS on statistical risk parameters — ratio anomalies, large refund claims, high-value transactions reported by third parties — without any specific allegation of wrongdoing. Some cases are selected on 'mandatory' criteria unrelated to any suspicion of error. The notice itself does not indicate guilt; it indicates your return has been picked for a detailed review.
