Super Tax under Section 4C stacks on top of the standard 29% corporate rate, and it only bites once a company's taxable income crosses Rs. 150 million. Since being introduced through the Finance Act 2022, it has been renewed every year rather than phased out — so if your business is anywhere near that threshold, it's worth planning for as a permanent fixture rather than a one-off.
Who Falls Into the Super Tax Net
- Any company — banking or non-banking — with taxable income above Rs. 150 million.
- Individuals and AOPs, in the rare cases where personal income exceeds Rs. 150 million.
- Banking companies specifically, which face the levy regardless of the income tier they fall into.
Super Tax is calculated on the same taxable income figure used for ordinary corporate tax — it's added on top of the 29% rate, not charged instead of it.
2026 Rate Table by Sector and Income Band
- Banks — 10% super tax at every income level, bringing their total effective rate to 39%.
- High-impact sectors (cement, steel, sugar, fertilizer, oil & gas, LNG) — 10% once income passes Rs. 300 million, also a 39% total rate.
- Other companies, Rs. 150M–200M income — 1% super tax, 30% total.
- Rs. 200M–250M — 2% super tax, 31% total.
- Rs. 250M–300M — 3% super tax, 32% total.
- Above Rs. 300M (general sectors) — 4% super tax, 33% total.
The gap between a bank's 39% and a typical company's 33% adds up quickly at scale — on a billion rupees of taxable income, that 6-point difference is Rs. 60 million.
Working Through a Calculation
Manufacturing company example: taxable income of Rs. 350 million, general sector (not high-impact).
- Normal corporate tax: Rs. 350M × 29% = Rs. 101.5M
- Super tax (above Rs. 300M threshold): Rs. 350M × 4% = Rs. 14M
- Total tax bill: Rs. 115.5M — an effective rate of 33%
Bank example: taxable income of Rs. 500 million.
- Normal corporate tax: Rs. 500M × 29% = Rs. 145M
- Super tax (banking rate): Rs. 500M × 10% = Rs. 50M
- Total: Rs. 195M — an effective rate of 39%
Building It Into Advance Tax
Super tax has to be factored into the quarterly advance tax instalments required under Section 147. If a company crosses the Rs. 150 million threshold for the first time during the year, IRIS may initially base advance tax estimates on last year's figures — which won't reflect a new super tax liability. Companies expecting to cross the threshold should top up their own advance payments proactively, since underpayment triggers a default surcharge on the shortfall.
What It Means for Tax Planning
- Dividend timing — distributing profit before year-end can lower the taxable income base that super tax is calculated on.
- Capital expenditure — bringing forward asset purchases in a super-tax-triggering year uses depreciation to shrink the taxable base.
- Loss carry-forward — unused losses from prior years reduce both the normal tax base and the super tax base simultaneously.
- Group structuring — some corporate groups look at keeping individual legal entities below the Rs. 150 million mark, though anti-avoidance rules can disallow artificial splitting designed purely to dodge the threshold.
Who Is Exempt
- Approved non-profit and charitable organisations.
- FBR-recognised educational institutions and hospitals operating on a non-profit basis.
- Companies inside Special Economic Zones during their tax holiday window.
- Any entity whose taxable income stays under Rs. 150 million for the year.
Exemption status should be reconfirmed each year rather than assumed — a SEZ tax holiday expiring, for instance, can bring a previously exempt company into the super tax net without warning.
