Penalties imposed under Sections 182, 184 and 186 of the Income Tax Ordinance 2001 on tax assessments completed on or before 30 June 2002 under the repealed Income Tax Ordinance 1979 are unlawful and legally unsustainable, a five-member larger bench of the Supreme Court ruled on 11 August 2026. The judgment settles a decade-long conflict between two earlier three-member bench rulings and binds all revenue authorities and courts under Article 189 of the Constitution.

The bench and the case

The larger bench was headed by Justice Shahid Waheed and included Justice Naeem Akhter Afghan, Justice Malik Shahzad Ahmad Khan, Justice Aqeel Ahmed Abbasi and Justice Shakeel Ahmad. Justice Abbasi authored the 17-page judgment. The case arose from a tax dispute between taxpayer Khadim Hussain and the Regional Tax Office, Rawalpindi. The Commissioner Inland Revenue (Legal), Rawalpindi, had appealed against an October 2014 ruling of the Lahore High Court's Rawalpindi bench, which had upheld the deletion of penalties by the Commissioner of Inland Revenue (Appeals) and the Appellate Tribunal Inland Revenue. The Supreme Court dismissed the department's appeal.

The legal conflict resolved

The larger bench was constituted because two three-member benches of the Supreme Court had reached opposite conclusions. In Eli Lilly Pakistan (Pvt.) Ltd (2009 PTD 1392), the court held that assessments completed under the repealed Income Tax Ordinance 1979 must be governed strictly by the old law, and that amendments to Sections 122(5) and 122(5A) of the 2001 Ordinance were prospective only. A later bench of equal strength in Islamic Investment Bank Ltd (2016 SCMR 816) departed from that approach. The five-member bench has now declared that the Eli Lilly position was correct and that the Islamic Investment Bank ruling was "erroneous in law." The court also reinforced the principle that a co-equal bench cannot simply issue a conflicting judgment; it must instead refer the matter to the Chief Justice for constitution of a larger bench.

Why penalties cannot apply retrospectively

The court drew a sharp distinction between procedural provisions and those that create or enlarge a taxpayer's liability. While machinery provisions governing assessment, reopening or recovery may in some circumstances operate retrospectively, provisions that impose an additional fiscal or penal burden cannot: unless the legislature has used express language authorising retrospective effect. Sections 182, 184 and 186 of the 2001 Ordinance, the court held, do not merely regulate the mode of determining an existing tax liability. They authorise pecuniary consequences for acts of default, exposing the taxpayer to an additional statutory liability that did not exist under the 1979 Ordinance. The court stated: "It is, therefore, immaterial whether such a burden is described as a 'penalty' or an 'additional tax consequence'; in either event, its operation affects substantive rights and liabilities."

Practical effect for taxpayers and pending revenue cases

The ruling means that the Federal Board of Revenue and its field formations cannot impose or sustain penalties under Sections 182, 184 or 186 of the 2001 Ordinance on any assessment completed on or before 30 June 2002, even where that assessment was later reopened under Sections 122(5) or 122(5A) of the 2001 Ordinance. For affected taxpayers, the immediate next step is:

  • Identify any pending assessment or appeal in which penalties under Sections 182, 184 or 186 of the 2001 Ordinance have been imposed for a pre-July 2002 assessment year.
  • Bring the Supreme Court's larger-bench ruling to the attention of the relevant appellate forum or assessing officer and seek withdrawal or deletion of the penalty.
  • Where a penalty has already been paid under protest, consider filing a restitution or refund claim citing the binding precedent.

For the revenue authorities, the ruling requires a review of all pending penalty proceedings tied to pre-2002 assessments and the withdrawal of those that rely solely on the 2001 Ordinance's penalty provisions.
