ISLAMABAD, April 29: In a landmark ruling with far-reaching fiscal implications, the Federal Constitutional Court of Pakistan has upheld the constitutionality of the super tax imposed under Sections 4B and 4C of the Income Tax Ordinance, 2001, reinforcing the government’s authority to levy income-based taxes and bringing an end to years of legal uncertainty.
The judgment, delivered in the case of M/s DG Khan Cement Company Limited & Others v. Federation of Pakistan along with connected appeals, validates the Federal Board of Revenue’s (FBR) long-standing position and overturns contrary findings by some High Courts.
Spanning nearly 300 pages, the detailed verdict addresses complex constitutional and taxation issues. The Court ruled that the super tax under Section 4B—introduced through the Finance Act 2015 to support the rehabilitation of temporarily displaced persons for tax years 2015 to 2022—constitutes a valid tax on income under Entry 47 of the Federal Legislative List. It rejected arguments that the levy was a fee, clarifying that the stated purpose of a tax does not change its nature unless directly tied to a specific service.
The Court also upheld Section 4C, introduced via the Finance Act 2022, which imposes a super tax on high-earning individuals and certain sectors from tax year 2022 onwards. It declared the provision a self-contained taxation mechanism with its own framework for assessment and collection.
Importantly, the Court ruled that there is no constitutional prohibition on double taxation and affirmed that retrospective taxation is permissible in fiscal legislation unless explicitly restricted. It further observed that income may be defined differently under various tax provisions.
Addressing sector-specific taxation, the Court endorsed higher tax rates applied to 15 identified industries, noting that the classification was justified due to super-normal profits recorded by these sectors in tax year 2022. This finding reversed earlier High Court decisions that had challenged the differential treatment.
The ruling also reinforced the principle of judicial restraint in fiscal matters, stating that tax policy falls within the domain of Parliament. Judicial review, the Court emphasized, is limited to assessing legislative competence, constitutional compliance, and the absence of arbitrariness.
On procedural grounds, the Court confirmed that the FBR and Commissioner Inland Revenue—when duly authorized—are competent to initiate and defend legal proceedings in tax-related constitutional matters.
Legal proceedings saw representation from some of the country’s most prominent lawyers. The Federation and FBR were led by senior advocate Ms. Asma Hamid, alongside Raza Rabbani, Syed Ashtar Ausaf Ali, and Dr. Shahnawaz Memon. Taxpayers were represented by eminent counsels including Makhdoom Ali Khan, Khalid Javed Khan, Dr. Firogh Naseem, Rashid Anwar, Salman Akram Raja, Shahzad Elahi, and Mehmood Mirza.
Legal experts describe the verdict as one of the most significant developments in Pakistan’s tax jurisprudence in recent years. By settling key constitutional questions surrounding Parliament’s taxation powers and sector-specific levies, the decision is expected to enhance fiscal certainty and strengthen revenue collection for the national exchequer.
