Construction companies and contractors: provincial sales tax

Construction is a major services sector, and its sales tax treatment has features that catch contractors out: it is provincial, it often carries a reduced rate with a catch, and it is frequently subject to withholding. Add materials bought under the federal regime and projects spread across provinces, and a contractor's compliance needs careful handling. This guide lays out the essentials.

A provincial service, with federal materials

Construction and contractor services are services, so they fall under provincial sales tax administered by the authority for the province where the project is located — PRA, SRB, KPRA or BRA — with Islamabad projects under FBR. At the same time, the building materials a contractor buys are goods under the federal regime. So a construction business lives on both sides of the divide: it incurs federal sales tax on cement, steel and other materials it purchases, and it charges provincial sales tax on the construction service it provides. Keeping the two straight is the starting point.

The reduced-rate trade-off

Construction services commonly attract a reduced rate rather than the full standard provincial rate, in several provinces and subject to conditions. This is welcome, but it comes with the familiar catch: reduced-rate services generally do not allow input tax adjustment. A contractor on the reduced construction rate therefore typically cannot reclaim the input tax on its material purchases and other inputs — the reduced rate is offered instead of, not alongside, input recovery. Whether that is favourable depends on how material-heavy the work is, since a contractor with large input tax it cannot reclaim may find the reduced rate less generous than it first appears. The exact reduced rate and its conditions vary by province and change, so they must be confirmed with the relevant authority before pricing a project.

Withholding on construction payments

Construction and contractor payments are also frequently subject to sales tax withholding. Under a withholding arrangement, the client or a designated withholding agent deducts part or all of the sales tax and deposits it directly, rather than paying it over to the contractor to remit. This materially affects the contractor's cash flow and returns — the tax never passes through the contractor's hands, and the returns must reflect the amounts withheld. A contractor therefore needs to know, for each engagement, whether it falls within a withholding regime and how much will be withheld, because being surprised by withholding on a large certified payment can disrupt cash planning. This connects construction to the broader compliance discipline shared with other professional and contractor services.

Common mistakes

• Treating the construction service as federal, or the materials as provincial.
• Claiming input tax on materials while charging the reduced construction rate that blocks it.
• Failing to plan cash flow for sales tax withheld by clients on certified payments.
• Applying one province\'s rate to a project located in another.

Where it fits

Construction spans the federal-versus-provincial divide — provincial service, federal materials — and shares withholding and reduced-rate features with other contractor services. For province detail, see the Punjab (PRA) overview. The service is provincial and often reduced-rate; the materials are federal.

Where the rate actually comes from

Construction is one of the clearest reduced-rate categories, and in Punjab government civil works carry their own treatment without input tax adjustment, alongside legacy rates preserved for older public-sector projects. A contractor bidding public work needs the entry that matches the project, not the general construction line.

The standard rate is 16 per cent in Punjab and 15 per cent in Sindh, Khyber Pakhtunkhwa and Balochistan, with telecommunication services higher at 19.5 per cent and Islamabad Capital Territory administered by FBR. Sindh has also moved from a positive list to a negative list, so a Sindh service is taxable unless it is specifically exempt — if you concluded some years ago that you were outside the net, that conclusion needs re-testing. The full picture is in the rates by province guide; the authoritative figure for your own category is in the current working tariff published by Punjab Revenue Authority or the authority for your province.
