Zero-rated or exempt? The distinction that changes your input tax
Zero-rated and exempt are the two most confused terms in Pakistani sales tax, because they look identical on an invoice. Both show no tax. The difference is invisible on the document and decisive in the accounts.
The core difference
| Zero-rated | Exempt | |
|---|---|---|
| Within the charge? | Yes — taxable at a nil rate | No — outside the charge |
| Output tax charged | Nil | Nil |
| Related input tax | Generally recoverable | Generally not recoverable |
| Effect on margin | Broadly neutral | Input tax becomes a cost |
| Refund possible | Yes, in defined circumstances | No, because there is nothing to recover |
| Typical examples | Export of goods; specified supplies | Specified goods and services under the exemption schedule |
The distinction is statutory, not descriptive. Zero-rating is conferred by the Fifth Schedule to the Sales Tax Act 1990, exemption by the Sixth Schedule, and the charging provision for everything else is section 3. Input tax recovery follows section 8, which disallows input attributable to exempt supplies — which is why the two schedules produce such different economics from an identical zero on the customer's invoice.
Classifying correctly
Zero-rated, exempt and standard-rated compared
| Standard-rated | Zero-rated | Exempt | |
|---|---|---|---|
| Output tax charged to the customer | 18% | 0% | None |
| Input tax recoverable on related purchases | Yes | Yes | No |
| Counts toward the registration threshold | Yes | Yes | No |
| Appears in the return | Yes | Yes | Yes, as exempt supplies |
| Effect on the supplier's margin | Neutral | Neutral | Input tax becomes a cost |
Row two is the whole distinction. Both zero-rated and exempt mean the customer pays nothing — which is why they get confused — but only zero-rating preserves input recovery. An exempt supplier absorbs the tax on everything they buy.
Classification is done entry by entry against the schedules, not by industry label:
- Identify the supply precisely — the specific good or service, as it appears on your invoice.
- Check the schedules to the Sales Tax Act 1990 for federal supplies of goods, or the relevant provincial schedule for services.
- Note the conditions. Many entries are conditional — on end use, on the identity of the recipient, on documentation, or on a notification remaining in force.
- Check for amendment. Schedule entries move through Finance Acts and notifications, so a classification correct two years ago may not be correct now.
- Record the basis with the date checked, so the position can be defended without redoing the analysis.
Where your supply does not clearly match an entry, do not choose the reading that suits your pricing. That is the situation for a written clarification, because reclassification during an audit reaches back across periods.

Most businesses in this territory make some taxable, some exempt and sometimes some zero-rated supplies. The consequence is apportionment:
- Input tax wholly attributable to taxable or zero-rated supplies is generally claimable in full.
- Input tax wholly attributable to exempt supplies is generally not claimable.
- Input tax on shared costs requires apportionment on a reasonable, consistently applied basis.
Identify the wholly-attributable inputs first and apportion only the residue — sweeping everything into the apportionment understates your claim. Input versus output tax works through the method.
What this means for pricing
The classification changes your cost base, so it has to reach your pricing:
- Exempt supplies carry embedded input tax. If you price as though inputs were recoverable, you are giving away the input tax. Build the unrecoverable element into the price.
- Zero-rated supplies are broadly neutral but generate a credit position, which is a cash timing issue rather than a cost. Plan working capital around it.
- A change in a schedule entry changes your margin, not just your compliance. Monitor entries relevant to your main lines rather than reviewing them annually.
- Provincial reduced rates behave like exemption for input purposes in several regimes, where recovery is restricted as the trade-off for the lower rate — Punjab services tax.
What each means for whether you register at all
The classification affects the registration decision, not just the return:
| Supply profile | Registration consequence |
|---|---|
| Wholly zero-rated | Registration is generally valuable — it is what unlocks input recovery, and a persistent credit position is normal rather than a problem |
| Wholly exempt | Registration brings obligations with little benefit, since input recovery is generally unavailable |
| Mixed taxable and exempt | Registration is usually required, with apportionment as an ongoing discipline |
| Mixed zero-rated and exempt | The hardest profile — some inputs recoverable, some not, and the apportionment carries real money |
An exempt-only business that registers voluntarily takes on monthly returns, invoicing discipline and audit exposure while gaining little. That is a decision to model rather than to make by default, and it is worth revisiting whenever your supply mix shifts materially.
Evidencing the position
- On the invoice: state that the supply is zero-rated or exempt and reference the basis.
- In the return: report exempt and zero-rated supplies in their own fields rather than merging them with taxable turnover — filing the return.
- In the file: keep the schedule entry relied on, the date checked, and any conditions with the evidence that they were met.
- For zero-rated exports: retain the export documentation for each shipment, because the zero-rating depends on it.
A nil-tax invoice with no stated basis is the weakest position available: neither party can show why no tax was charged, and the default assumption in a review is that it should have been.

Questions people also ask
If both mean no tax charged, why does the distinction matter?
Because of what happens to the tax you paid on your own purchases. Zero-rating generally preserves your right to recover input tax, so the supply chain stays neutral. Exemption generally removes it, so the input tax becomes a cost you absorb or build into your price. Two businesses with identical revenue and identical purchases can have materially different margins depending on which applies.
How do I find out which category my product falls in?
From the schedules to the Sales Tax Act 1990 for federal supplies, and from the relevant provincial schedule for services. Classification is entry by entry against the description in the schedule, not by industry category. If your product does not clearly match an entry, that is a question worth resolving in writing rather than deciding internally.
Can I still register if all my supplies are exempt?
Registration where all supplies are exempt brings obligations without the main benefit, since input recovery is generally unavailable. There can still be reasons to register — a mixed supply profile, a customer requirement, or an expectation that the position will change. Model it before registering voluntarily rather than after.
Do I need to show anything on the invoice for these supplies?
Yes. State that the supply is zero-rated or exempt and, ideally, reference the basis. An invoice showing nil tax with no explanation leaves both parties unable to evidence why no tax was charged, which is exactly the gap a reviewer probes.
Is export of goods zero-rated or exempt?
Export of goods is generally zero-rated rather than exempt, which is why exporters can be in a persistent input tax credit position and why a refund mechanism exists for them. The conditions attached to zero-rating exports — including documentation of the export itself — have to be met and evidenced for each shipment.
