Zero-Rated vs Exempt Supplies Under Pakistani Sales Tax

In Pakistan's sales tax system, not every supply is taxed at the standard rate. Two categories often cause confusion: zero-rated supplies and exempt supplies. On the surface they look the same — the buyer pays no sales tax either way. But the difference matters a great deal for your business, because they treat input tax very differently.

Getting this right affects how much tax you can recover and how you complete your return. This guide explains both terms in plain language.

What is a zero-rated supply?

A zero-rated supply is still a taxable supply — it is just taxed at a rate of 0%. The buyer pays no sales tax, but because the supply is within the tax system, you can generally still reclaim the input tax you paid on the purchases and expenses used to make that supply.

The classic example is exports. When you export goods, you charge 0% GST, yet you can still recover the input tax on the raw materials and costs that went into producing them. This keeps exports competitive by ensuring tax does not get stuck in the supply chain.

What is an exempt supply?

An exempt supply is outside the scope of sales tax altogether. No sales tax is charged to the buyer — but crucially, you generally cannot reclaim the input tax on purchases relating to that exempt supply. That input tax becomes a cost to your business.

So while both zero-rated and exempt supplies mean the customer pays no tax, the exempt route can leave you out of pocket on the tax embedded in your costs.

The key difference at a glance

Why the input tax point matters so much

Imagine two businesses that both sell to customers without charging sales tax. The one making zero-rated supplies can recover the tax it paid on its inputs, keeping its true cost down. The one making exempt supplies cannot, so that input tax quietly increases its cost base. For understanding how input and output tax interact, see our guide on input tax vs output tax adjustment.

Key point: "no tax charged" does not tell the whole story. Whether you can recover your input tax is what really separates zero-rated from exempt.

Which supplies fall into each category?

The specific goods and supplies that are zero-rated or exempt are set out in the sales tax law and its schedules, and they are reviewed in the annual budget. Categories can be added or removed, and conditions often apply. Because of this, you should not rely on an old list. Instead:

• Check the current schedules and notifications that apply to your goods;
• Confirm any conditions attached to the treatment;
• Ask FBR or a tax adviser if your specific product is unclear.

Mixed supplies: a common complication

Many businesses make a mix of taxable, zero-rated and exempt supplies. In that situation you may only be able to reclaim part of your input tax — the portion relating to your taxable and zero-rated activity. Apportioning input tax correctly is fiddly and easy to get wrong by hand, which is where proper accounting software helps.

Frequently asked questions

Is exporting zero-rated or exempt?

Exports are generally treated as zero-rated, which is why exporters can typically reclaim input tax on their costs. Always confirm the current treatment and any conditions for your particular goods with FBR.

If both mean no tax to the customer, why does the difference matter?

Because of input tax. Zero-rating usually lets you recover the tax on your purchases; exemption usually does not, turning that tax into a cost you absorb.

How do I know which category my product is in?

The classification comes from the sales tax law and its schedules, which change over time. Check the current position for your specific goods with FBR or a qualified adviser rather than relying on memory.

Iris Accounts lets you flag each item as standard, zero-rated or exempt and handles the input-tax treatment for you, so your returns stay accurate even when your supplies are mixed.
