The Supreme Court of Pakistan has ruled that penalties imposed under the Income Tax Ordinance 2001 cannot be applied retrospectively to tax assessments completed under the repealed Income Tax Ordinance 1979, declaring such penalties unlawful and legally unsustainable.
A five-judge larger bench headed by Justice Shahid Waheed delivered the judgment, which also settled a long-standing conflict between two earlier Supreme Court rulings on whether amendments to tax laws could apply to assessments governed by previous legislation.
The court held that the 2009 ruling in the Eli Lilly Pakistan case represented the correct legal position, while the contrary view taken in the 2016 Islamic Investment Bank case was erroneous. Assessments completed under the repealed law, the court said, must remain governed by that law unless Parliament has clearly provided otherwise.
The case before the court involved a taxpayer, Khadim Hussain, who had purchased a property in 1999 but had not filed a corresponding tax return. Tax authorities later initiated proceedings and issued an ex parte assessment under the repealed 1979 Ordinance, adding Rs. 300,000 to his taxable income for the assessment years 2000-2001 through 2002-2003.
The tax department also imposed penalties under the 2001 Ordinance. However, the Commissioner of Income Tax Appeals subsequently deleted the penalties while maintaining the income addition — a position upheld by both the Income Tax Appellate Tribunal and the Lahore High Court.
The tax department then approached the Supreme Court, arguing that penalties under the 2001 Ordinance could be imposed. The larger bench rejected that position and dismissed the department’s appeal.
In its judgment, the court emphasised that in the absence of clear legislative language giving a tax provision retrospective effect, provisions of the 2001 Ordinance could not be applied to assessments governed by the 1979 law. Substantive rights and liabilities of taxpayers, the court said, crystallise under the law applicable to the relevant assessment year and cannot later be increased through subsequent legislation.
The ruling further held that penal amendments or provisions increasing a taxpayer’s liability must generally apply prospectively unless Parliament expressly provides for retrospective application.
The judgment effectively resolves the legal conflict between the two earlier Supreme Court rulings and establishes a clear precedent: later tax penalties cannot be imposed on assessments governed by an earlier tax law unless the legislation expressly provides for retrospective application.
