Super Tax in Pakistan After the Federal Constitutional Court Ruling: Section 4C and the 2026 Rates
On 27 January 2026 the Federal Constitutional Court held that super tax under sections 4B and 4C of the Income Tax Ordinance, 2001 is constitutional, and set aside the High Court judgments that had struck down or read down section 4C. From tax year 2027 the Finance Act, 2026 charges super tax at 8% only where income exceeds Rs 500 million, keeps 10% above Rs 150 million for banking, fertilizer and Fifth Schedule (exploration and production) businesses, and exempts exporters whose realised export proceeds exceed 80% of turnover.
For three years super tax was litigated as a constitutional question. That phase is over. Companies looking for the best tax lawyer in Karachi, Pakistan on super tax now need computation arguments, not vires arguments, because what remains open is how much of a particular taxpayer's income the levy actually reaches.
What super tax is
Pakistan has two super tax provisions in the Income Tax Ordinance, 2001. Section 4B is the older levy, introduced from tax year 2015 for the rehabilitation of temporarily displaced persons. Section 4C was inserted by the Finance Act, 2022 as a tax on high-earning persons and applies from tax year 2022. It is charged on “income” as defined in section 4C itself, which is wider than taxable income: it brings in profit on debt, dividends, capital gains, brokerage and commission, taxable income (before brought-forward depreciation and business losses), imputable income, and income computed under the Fourth, Fifth, Seventh and Eighth Schedules.
Up to tax year 2026 the rates rose in slabs to a top rate of 10% where income exceeded Rs 500 million.
What the Federal Constitutional Court decided
The challenges had produced conflicting results. The Islamabad High Court held that section 4C, as it then stood, was ultra vires; other High Courts upheld it in part or read it down, particularly on its retrospective application to tax year 2022. On 27 January 2026 a three-member bench of the Federal Constitutional Court, headed by Chief Justice Aminuddin Khan, dismissed the taxpayers' petitions, held sections 4B and 4C intra vires, and set aside the judgments of the Islamabad, Lahore and Sindh High Courts that had struck down or read down section 4C.
According to the court's short order and the detailed judgment that followed in April 2026:
- Section 4B applies as enacted from tax year 2015 onwards, at the prescribed rates.
- Section 4C applies as enacted from tax year 2022. Retrospective application was upheld because returns for tax year 2022 had not yet been filed when the levy was introduced.
- For banking companies, section 4C applies from tax year 2023 at the amended rates.
- For exploration and production companies, sections 4B and 4C apply only to the extent that the aggregate tax does not exceed the ceilings in the Fifth Schedule and the company's petroleum concession agreement. Those cases go back to the Commissioner individually.
- Super tax is an additional charge, not a replacement for income tax, and reaches income under separate or final tax regimes. Income that is exempt from tax stays outside it.
The Finance Act, 2026 changes
From tax year 2027 the Finance Act, 2026 restructured section 4C:
- Banking companies, persons covered by the Fifth Schedule (petroleum exploration and production), and persons deriving income from the sale of fertilizer: 10% where income exceeds Rs 150 million.
- All other persons: 8% where income exceeds Rs 500 million. Super tax no longer applies to these persons below that threshold.
- Exporters: super tax does not apply where export proceeds realised for the tax year are more than 80% of total turnover for that year.
The relief is prospective. Demands for tax years 2022 to 2026 are governed by the rates that applied to those years, as the Federal Constitutional Court confirmed.
What is still worth contesting
With the constitutional question settled, disputes now turn on application and computation. The points we see most often are:
- What counts as “income” under section 4C for the particular taxpayer, and whether an item is genuinely exempt rather than merely taxed under a separate regime.
- Sector classification under the Finance Act, 2026, which decides whether the 8% or 10% schedule applies.
- The export proceeds test: whether proceeds were realised in the tax year and how turnover is measured.
- The E&P ceiling under the Fifth Schedule and the concession agreement, which the court expressly left to the Commissioner.
- Credits and adjustments for super tax already paid, and the order in which demands are recovered.
These are fought through the ordinary appeal chain: Commissioner (Appeals) or the Appellate Tribunal Inland Revenue, then a reference to the High Court on a question of law. See our guide to the tax appeal route.
If you have a super tax notice or demand
Check first which tax year it relates to, which rate schedule the department has applied, and whether the computation of “income” includes items that are exempt. Then look at deadlines: appeal periods under the 2024 amendments are short, and recovery is not suspended merely because an appeal has been filed. Our tax and customs practice handles super tax matters from notice stage through the Appellate Tribunal, the High Court of Sindh and the Supreme Court.
Common questions
Is super tax still valid after the Federal Constitutional Court decision?
Yes. On 27 January 2026 the Federal Constitutional Court held sections 4B and 4C of the Income Tax Ordinance, 2001 to be constitutional and set aside the High Court judgments that had struck down or read down section 4C. Challenges now turn on how the levy is computed and applied, not on whether it is valid.
From which tax year does super tax under section 4C apply?
Section 4C applies as enacted from tax year 2022, and the Federal Constitutional Court upheld that retrospective application because returns for tax year 2022 had not been filed when the levy was introduced. For banking companies it applies from tax year 2023 at the amended rates. Section 4B applies from tax year 2015.
What are the super tax rates from tax year 2027?
Under the Finance Act, 2026: 10% where income exceeds Rs 150 million for banking companies, Fifth Schedule (exploration and production) businesses and fertilizer sellers; 8% where income exceeds Rs 500 million for everyone else. Other persons with income up to Rs 500 million no longer pay super tax.
Are exporters exempt from super tax?
From tax year 2027, super tax does not apply to a person whose export proceeds realised for the tax year are more than 80% of total turnover for that year. Earlier tax years are governed by the law as it then stood.
Does super tax apply to income taxed under the final tax regime?
According to the Federal Constitutional Court's detailed judgment, super tax reaches all income, including income under separate tax regimes, but income that is exempt from tax is not subject to it. Whether a particular item is exempt or merely separately taxed is often the real dispute.
