Super tax under section 4C: what changed for Tax Year 2027

Super tax was introduced from Tax Year 2022 as an additional charge on high-earning persons, and it grew into one of the more resented features of the Pakistani corporate tax landscape. The Finance Act 2026 narrowed it substantially. Understanding exactly how far the relief goes matters, because the shorthand circulating — that super tax has been abolished — is not accurate.

What the Finance Act 2026 did

The Act abolished super tax for persons whose income does not exceed Rs 500 million, other than three excluded categories. The intermediate slabs that previously applied between the lower threshold and Rs 500 million — running from 1% up to 7.5% — were removed.

For the great majority of Pakistani companies this is a genuine removal of a real cost. For large corporates, banks and the named sectors, it is not. See the Finance Act 2026 register for the wider set of changes.

The rate that survives, and the two that did not

The charge sits in section 4C of the Income Tax Ordinance 2001, with the rates in Division IIB, Part I of the First Schedule. Naming the numbers matters here because the relief is a rate cut as well as a threshold change.

What the change is worth

Two companies, both outside the excluded sectors, on the corporate rate of 29%.

Company A's entire charge disappears; Company B keeps a charge but pays two percentage points less, worth Rs 18,000,000 on this income. Note the shape of the relief: it is largest in absolute terms for the company just under Rs 500 million, and a company at Rs 505 million pays 8% on the whole Rs 505 million rather than on the excess — so the Rs 500 million line is a cliff, not a slab boundary. Income measured at Rs 495 million versus Rs 505 million is a difference of roughly Rs 40 million in tax on Rs 10 million of income, which makes the year-end income computation worth getting exactly right.

The export exemption in practice

The new provision excludes a person from super tax where export proceeds realised for the tax year represent more than 80% of income. Three operational points follow, and they mirror the conditions attached to the IT export concession:

• Realised, not invoiced. The test refers to proceeds realised, so receipts still sitting with a foreign customer or in a platform balance do not count toward the percentage.
• The banking trail is the evidence. Proceeds realisation certificates and bank credit advice are what establish the numerator — see remittance evidence.
• Timing across the year end matters. A large receipt landing days after 30 June can move you from above the threshold to below it for that year.

An exporter close to the 80% line should manage collection timing deliberately rather than discovering the position after the year has closed.

Where super tax sits in the total burden

Super tax is an additional charge, not a substitute and not a credit. For a company within the charge, the layers stack:

1. Corporate tax on taxable income at 29%, or a concessionary rate where applicable — corporate tax basics.
2. Minimum tax on turnover under section 113 where regular tax falls below 1.25% of turnover — minimum tax.
3. Super tax under section 4C where the income threshold is met.
4. A further layer when profit is distributed to shareholders.

Why the change matters more than it looks

Super tax was introduced from Tax Year 2022 as a temporary measure and then persisted, which is the specific reason businesses stopped treating it as temporary and started building it into pricing. Its narrowing is therefore a planning event rather than a windfall:

• Pricing built around it can be revisited. A business that priced contracts to absorb a super tax charge it no longer bears has recovered margin it may choose to keep or compete with.
• Advance tax instalments need revising, because instalments calculated on a prior-year liability that included super tax will now overfund the position and tie up cash recoverable only through the return.
• Deferred tax positions change where the rate applied to temporary differences included a super tax component.
• The threshold is now the whole question. With the intermediate slabs gone, the charge is effectively binary around Rs 500 million for most persons — which makes income near that figure worth computing carefully rather than approximately.

Because the relief was delivered by removing slabs rather than by repealing the section, the mechanism remains on the statute book and can be re-expanded by a future Finance Act. Treat the current position as the law for this year rather than as a settled state.

What to do this year

1. Test your income against Rs 500 million on the correct statutory basis, not on accounting profit.
2. Confirm you are not in an excluded sector. Banking, oil and gas exploration and fertilizer sales remain within the charge.
3. If you export, compute the realised-proceeds percentage and keep the banking evidence supporting it.
4. Revise advance tax instalments where you are now outside the charge. Continuing to fund a liability that no longer applies ties up cash you can recover only through the return.
5. Document the basis for your position in the tax year file, because a change from paying to not paying invites the question of why.

Because super tax operates at thresholds, the taxpayers most affected by this change are precisely those for whom the numbers are largest. If your income is near Rs 500 million or your export percentage is near 80%, have the position reviewed before the instalments are set.
