The short order of the Federal Constitutional Court (FCC) of Pakistan of January 27, 2026 on super tax, imposed under sections 4B and 4C of the Income Tax Ordinance, 2001 [“the Ordinance”], stirred intense constitutional debates and generated multiple controversies.

Now, the detailed judgment released on the website of FCC on April 29, 2026, exposes the real fault line. The Court holds:
“Section 4C is a distinct charge on a distinctly defined base of income, taking nothing away from the charge of tax under Section 4 or from the final, minimum, or separate regimes elsewhere in the statute. It contains its own machinery for collection and recovery, distinguishable from taxable income and other regimes under the Ordinance” [Para 58].
The additional note authored by Mr. Justice Syed Hasan Azhar Rizvi, while endorsing this reasoning, attempts to provide doctrinal legitimacy to what is, in substance, an unprecedented expansion of the State’s taxing power. The note declares that section 4C, being an “additional duty” of income tax, does not amount to constitutionally prohibited double taxation, and that even if taxation is onerous, it does not infringe Articles 4, 18, 23 or 24 of the Constitution of the Islamic Republic of Pakistan [“the Constitution”]. This formulation appears, at first glance, to be anchored in settled principles. A closer reading reveals that it unsettles those very principles.
This is not the first time such reasoning has been advanced. In earlier writings on this subject, it was repeatedly argued that the controversy surrounding super tax is not about fiscal necessity or revenue mobilisation; it is about constitutional limits. The Constitution permits taxation, but it does not permit taxation without boundaries or beyond legislative competence. Once those limits are blurred, the entire structure of supreme law of the land begins to erode.
The starting point of the additional note is the characterisation of super tax as an “additional levy” on income. That characterisation is the core of the problem. In fiscal jurisprudence, an additional levy presupposes an existing and properly computed tax liability. It operates as a surcharge or enhancement upon that liability. It does not alter the base itself.
Section 4C does not merely add to the tax determined under section 4 of the Ordinance. It reconstructs the very concept of income by excluding losses, depreciation and other recognised adjustments, and then imposes a fresh burden on that reconstructed figure. This is not an addition in any meaningful legal sense; it is a re-computation followed by re-taxation. The distinction is not semantic; it is constitutional.
The High Courts, as noted by the FCC, have “repeatedly observed in the section 4B litigation, [that super tax has] been recognised as a settled feature of the tax regime since the Super Tax Act, 1917; the phrase ‘in addition to’, in that context, would be a surplusage rather than a requirement”. Interestingly, the Court has not traced and/or reproduced the text or history of the Super Tax Act, 1917.
The Super Tax Act, 1917, properly understood in its historical context, did not emerge as an ordinary extension of income taxation. It was conceived as an extraordinary wartime fiscal instrument, fundamentally different in character, purpose and justification from modern “super taxes” like sections 4B and 4C of the Ordinance. It targeted either higher income classes through progressive rates or abnormal gains arising from exceptional circumstances. It did not recompute income by denying legitimate deductions nor impose repeated taxation on the same taxable event.
The Super Tax framework of 1917 was born out of necessity but shaped by principle. It recognised that taxation must remain anchored in distinct taxable events or justified differentiation. Its purpose was not to multiply taxes, but to ensure fairness in extraordinary circumstances. Any attempt to equate that historical model with contemporary levies that re-compute and re-tax the same income ignores both its text and its philosophy.
This historical omission dismantles the reasoning of the FCC. It is not merely incomplete; it is factually inaccurate. If accepted, the implications are far-reaching. The legislature can impose successive layers of taxation by simply redefining income each time. Today it is super tax; tomorrow it may be another levy under a different name. The taxable event remains unchanged, yet the burden multiplies.
In earlier articles mentioned above, it was cautioned that such an approach would convert Entry 47, Part I of the Federal Legislative List into a fiscal vacuum, permitting repeated taxation of the same income without constitutional restraint. The additional note does not address this concern; it reinforces it.
The assertion that there is no constitutional prohibition on multiple taxes under Entry 47 is equally problematic. The issue has never been whether double taxation is absolutely barred. The real question is whether the same taxable event can be subjected to repeated taxation without constitutional justification.
Courts have consistently distinguished between taxes operating on different aspects of a transaction and those that merely replicate the same burden. That distinction is fundamental. By treating the absence of an express prohibition as a licence for multiplicity, the additional note overlooks the structural limits inherent in constitutional entries. A Constitution does not enumerate every prohibition; it defines boundaries. To ignore those boundaries is to expand power beyond its intended scope.
The treatment of fundamental rights in the additional note reflects a similar simplification. It is observed that taxation, even if onerous, does not infringe Articles 4, 18, 23 or 24. No serious argument has ever suggested that taxation must be light to be constitutional. The issue is not the quantum of tax; it is the authority to impose it.
Articles 23 and 24 protect property against deprivation except in accordance with law. When a tax is imposed beyond constitutional competence, it is not merely burdensome; it is without lawful authority. In earlier writings, it was emphasised that retention of tax collected on an artificially recalibrated base amounts to compulsory exaction.
The additional note reduces this to a question of reasonableness, thereby missing the essential constitutional point. The Constitution protects against unlawful taxation, not merely against excessive taxation.
The interpretation of Entry 47 in the main order and additional note has the most profound consequences. By accepting that multiple levies on income are permissible, it transforms a defined taxing field into an open-ended fiscal power. Entry 47 authorises taxes on income; it does not authorise repeated taxation of the same income under different statutory forms. If multiplicity alone is treated as constitutionally permissible, there is no logical limit to fiscal layering.
Income may be taxed repeatedly, each time justified by a separate provision. In earlier critiques published in these pages, it was warned that such an interpretation would destroy the doctrine of taxable event and render constitutional limitations meaningless. The additional note effectively adopts that interpretation without confronting its implications.
Equally striking is the silence on Entry 52. The Constitution permits certain capacity-based taxes only where they operate “in lieu of” other taxes. This phrase is restrictive. It embodies a constitutional compromise that allows departure from normal income taxation only where substitution takes place. Super tax does not substitute income tax; it is imposed in addition to it. This distinction was central to earlier analyses, yet the additional note bypasses it entirely. By validating a tax that is plainly cumulative, the constitutional safeguard embedded in Entry 52 is rendered ineffective. The difference between substitution and addition, which is central to the scheme of taxation, is collapsed.
The historical justification often invoked for multiple taxation also fails to support the reasoning of the additional note. Excess profits tax, super tax and business profits tax were imposed in exceptional circumstances and targeted extraordinary gains. The taxable event was not ordinary income but excess or abnormal profit arising from specific conditions. Their coexistence with income tax was justified because they addressed a different economic phenomenon.
Super tax under sections 4B and 4C does not operate in that space. It targets ordinary income, albeit through a distorted base. The analogy, therefore, is misplaced. Earlier writings had already pointed out this distinction, yet the additional note adopts the historical comparison without examining its substance.
The cumulative effect of the reasoning in the main order and additional note is deeply unsettling. It legitimises repeated taxation of the same income, allows the taxable base to be manipulated to increase burden, expands Entry 47 beyond its constitutional limits, and weakens the safeguards embedded in Entry 52. This is not a minor doctrinal shift; it is a reconfiguration of constitutional limits on taxation.
The consequences extend beyond the immediate case. Once the same income can be taxed repeatedly, the taxpayer is left without a meaningful constitutional defence. Each levy can be presented as distinct, even though its incidence is identical.
The burden may become confiscatory, yet the formal requirements of separate enactment provide a shield against challenge. This is precisely the scenario that constitutional jurisprudence sought to prevent.
The additional note, in attempting to justify super tax as merely an “additional duty” of income tax, removes the conceptual boundary between lawful taxation and unconstitutional duplication. In earlier articles, it was warned that such reasoning would lead to taxation without limits, disguised as legality. That warning now stands vindicated. The Constitution does not prohibit taxation; it prohibits taxation beyond defined limits. Once those limits are diluted, the distinction between taxation and expropriation begins to fade.
The debate on super tax is, therefore, no longer confined to a single provision. It has become a test of whether constitutional boundaries on fiscal power will be preserved or eroded. The judgment of FCC, by treating multiplicity as permissible, shifts the balance decisively in favour of the State. Whether that shift will endure remains to be seen. What is clear, however, is that the constitutional questions raised by super tax are far from settled. The review petitions pending against FCC’s verdict have strong prospects of success, as the detailed judgment contains errors of law apparent on the face of the record.
