Can you claim input tax the supplier never deposited?

You hold a valid tax invoice, you paid your supplier the price plus sales tax, and you claim that tax as input credit. Then FBR disallows it — because your supplier never declared or paid the tax. This is one of the most consequential features of Pakistan's sales tax system: your input credit depends not just on your own invoice, but on your supplier's compliance. Understanding it protects your cash and your exposure.

Input tax follows the supplier's compliance

The Sales Tax Act makes input tax not admissible where, at the time the buyer files its return, the supplier has not declared the supply in its own return, or has not paid the tax shown as due on it. The significance is hard to overstate: a valid-looking tax invoice is not enough on its own. If the supplier who issued it never accounts for the tax to FBR, your input claim on that purchase can be disallowed — leaving you having paid the tax to the supplier but unable to recover it as credit. The credit is, in effect, conditional on the supplier's behaviour downstream, not only on the paperwork in your hands.

Cross-matching finds the gap

FBR enforces this through cross-matching. Buyer and supplier sales tax returns are matched against each other, so a purchase on which you claim input tax is checked against whether the corresponding supplier declared and paid it. A mismatch — you claiming input, the supplier not declaring or not paying output — is precisely what the system is built to surface. So claims against non-compliant suppliers do not stay hidden; they are flagged by the matching process. On top of disallowance, joint-and-several liability rules can extend exposure to the buyer where a supplier has not paid, meaning the buyer can be pursued for tax the supplier failed to deposit. The risk is therefore not only losing the credit but potentially being chased for the shortfall.

Protecting your claims

Because the risk sits partly outside your control, the defence is in who you buy from and how you document it. Deal with compliant, active registered suppliers; check a supplier's active taxpayer status before relying on its invoices; keep proper tax invoices; and make payments through banking channels as the rules require. None of this guarantees that a given supplier will actually pay — but buying from suppliers with a good compliance record and documenting every purchase substantially reduces the chance of a disallowed claim and of joint-liability exposure. In practice, supplier due diligence is not an optional nicety in Pakistan's system; it is part of protecting your own input tax.

Common mistakes

• Assuming a valid tax invoice alone secures the input tax claim, regardless of the supplier.
• Not checking whether suppliers are active and compliant before relying on their invoices.
• Paying outside banking channels and weakening the claim.
• Overlooking that joint-and-several liability can extend to the buyer for a supplier\'s unpaid tax.

Where it fits

This is the hard edge of the input-versus-output tax mechanism and a direct reason the active taxpayer list matters so much. It works alongside the ordinary input-tax adjustment rules and applies to every registered buyer. Your invoice is necessary but not sufficient; your supplier has to pay.
