The Federal Constitutional Court’s long-awaited detailed judgment released on April 29, 2026 (short order was announced on January 27, 2026) upholding super tax imposed under sections 4B and 4C of the Income Tax Ordinance, 2001, does not merely settle a tax dispute. It unsettles settled constitutional jurisprudence on taxing powers of Parliament. The judgment proceeds on a set of core findings. Each, when examined against constitutional structure, doctrine, and comparative jurisprudence, fails to withstand scrutiny. If multiplicity alone is accepted as constitutional justification, then no limiting principle survives. The Court’s foundational finding is that Parliament is competent under Entry 47, Part I, Federal Legislative List (FLL), Fourth Schedule to the Constitution of Islamic Republic of Pakistan [“the Constitution”] to impose multiple taxes on income, and that super tax is simply another such levy. This conclusion collapses the distinction between power to tax income and power to tax the same taxable event repeatedly. Entry 47 is not a revenue maximisation clause. It is a field allocation provision. The phrase “taxes on income” identifies the subject-matter of taxation, not the number of times that subject may be taxed. If multiplicity alone is accepted as constitutional justification, then no limiting principle survives. At the centre of the judgment lies a proposition that is deceptively simple yet profoundly consequential: Parliament may impose multiple taxes on income under Entry 47 of the Federal Legislative List. Super tax, according to the Court, is just another such levy—independent, self-contained and constitutionally valid. This conclusion, once examined beyond its formal language, transforms a constitutional boundary into an open-ended fiscal licence. The Constitution does not confer an unlimited power to tax. It allocates fields of taxation between the federation and the provinces under a carefully structured scheme. Entry 47 authorises “taxes on income”. It identifies a subject—income—not a permission to tax that subject repeatedly under different statutory devices. If the same income can be subjected to multiple levies merely because each is placed in a separate charging provision, the entry ceases to operate as a constitutional limit. It becomes a fiscal vacuum. The Court’s reasoning rests almost entirely on legislative form. Section 4C of the Income Tax Ordinance, 2001 [“the Ordinance”], it observes, is a distinct charging provision; it defines its own base and contains its own machinery for collection and recovery. From this, it concludes that the levy is constitutionally separate from income tax under Section 4 of the Ordinance. This is a familiar but flawed approach. Constitutional validity does not depend on how a tax is drafted but on what it taxes. The doctrine of taxable event remains the governing test. Income tax under Section 4 attaches to the earning of income within a tax year. Super tax under Section 4C attaches to precisely the same event. It does not arise from a separate activity or transaction. It does not identify a new economic occurrence. It simply takes the same income and imposes an additional burden upon it. Calling it “independent” does not alter its character. A second tax on the same taxable event, disguised through computational manipulation, cannot be legitimised by describing it as additional. The danger of the Court’s reasoning lies in the precedent it creates. If a separate charging provision is sufficient to establish a separate tax, there is no logical limit to fiscal multiplication. Income may be taxed repeatedly—through super tax, additional super tax, or any future levy—each justified by its formal independence. Legislative ingenuity replaces constitutional discipline. The additional note goes even further. It holds that super tax, being an “additional levy”, does not amount to constitutionally prohibited double taxation and that even onerous taxation does not infringe fundamental rights. This proposition, though superficially appealing, collapses upon closer scrutiny. An “additional” levy, in constitutional and fiscal jurisprudence, operates upon an already determined tax liability. It enhances; it does not reconstruct. Section 4C of the Ordinance does not merely add to income tax. It recalibrates income itself by excluding losses, depreciation, and other recognised adjustments, and then imposes a fresh burden on that altered base. This is not an increment; it is a re-computation followed by re-taxation. Once the base is altered, the levy ceases to be additional and becomes duplicative in substance. The distinction is not academic. It goes to the heart of constitutional competence. A second tax on the same taxable event, disguised through computational manipulation, cannot be legitimised by describing it as “additional”. The observation that onerous taxation does not violate fundamental rights is correct in the abstract but misplaced in this context. The issue is not whether taxation is heavy or light. It is whether it is constitutionally authorised. Articles 23 and 24 of the Constitution protect property against deprivation except in accordance with law. A tax imposed beyond constitutional limits is not merely burdensome; it is without lawful authority. The Constitution protects against unlawful exaction, not merely excessive exaction. The judgment’s interpretation of Entry 47 has consequences that extend far beyond this case. By accepting that multiple levies on income are permissible, it transforms a defined taxing field into an unlimited fiscal space. Once this door is opened, there is no principled basis to close it. The same income may be taxed repeatedly, each time under a new statutory formulation. Equally, troubling is the treatment—or rather the absence of treatment—of Entry 52, Part I of FLL. The Constitution permits certain capacity-based taxes only where they operate “in lieu of” other taxes. This phrase is not incidental; it is restrictive. It embodies a constitutional compromise: departure from normal income taxation is permissible only where substitution occurs. Super tax does not substitute income tax; it is imposed in addition to it. By validating such a levy without addressing this limitation, the judgment effectively renders Entry 52 redundant. The historical analogies relied upon to justify multiplicity are equally misplaced. Super tax, excess profits tax and business profits tax, as developed in earlier regimes, were imposed in exceptional circumstances and targeted extraordinary gains. The taxable event was not ordinary income but excess or abnormal profit. Their coexistence with income tax was justified because they addressed a different economic phenomenon. Super tax under Sections 4B and 4C does no such thing. It taxes ordinary income again, albeit on a distorted base. Comparative jurisprudence does not support the Court’s approach. Across common law jurisdictions, courts have consistently examined the substance of a levy rather than its label. Where the same economic base is targeted, repetition of tax is scrutinised, not presumed permissible. The doctrine of pith and substance exists precisely to prevent such circumvention. The cumulative effect of the judgment is to weaken the constitutional safeguards that restrain fiscal power. Once the same income can be taxed repeatedly, the taxpayer is left without an effective constitutional defence. Each levy may be presented as distinct, even though its incidence is identical. The burden may become confiscatory, yet the Constitution offers no remedy because formal requirements are satisfied. This shift has broader implications. It enlarges the executive’s fiscal space in a system already characterised by limited parliamentary scrutiny. It disturbs the federal balance by expanding the scope of federal taxing powers. Most importantly, it alters the conceptual foundation of constitutional taxation by replacing substance with form. The Constitution does not forbid taxation. It forbids unbounded taxation. That distinction must not be allowed to disappear. The question is not whether the State requires revenue. It does. The question is whether constitutional limits on taxation are to be preserved or diluted in the process. A constitution is not merely a grant of power; it is a restraint upon it. When those restraints are interpreted away, the structure itself begins to erode. The super tax judgment is therefore not the end of the matter. It is the beginning of a deeper constitutional reckoning. Does Entry 47 permit repeated taxation of the same income? Can legislative drafting override the doctrine of taxable event? What remains of Entry 52 if “in lieu of” is read as “in addition to”? These are not abstract questions. They go to the integrity of the constitutional order. Many other violations and controversies relating to super tax vis-à-vis Constitution and other provisions of the Income Tax Ordinance, 2001 have already been discussed in ‘ Deeping super tax controversy ’, Business Recorder, April 17, 202 and ‘ Fallacies behind super tax validatio n’, Business Recorder, February 10, 2026. The Constitution does not forbid taxation. It forbids unbounded taxation. That distinction must not be allowed to disappear. Income can be taxed again and again by altering nomenclature—income tax, super tax, solidarity tax, reconstruction tax—each targeting the same taxable event. That interpretation renders the constitutional scheme otiose. The doctrine of pith and substance requires identification of the true taxable event. Here, the event remains the same: income. Merely creating another charging section does not create another constitutional field. The article does not necessarily reflect the opinion of Business Recorder or its owners.
