Sales Tax on Services: Navigating the Provincial Maze

A company that sells goods in Pakistan deals with one sales tax authority. A company that sells services can deal with five. The Eighteenth Amendment to the Constitution, passed in 2010, confirmed sales tax on services as a provincial subject, and each province responded by enacting its own statute and building its own revenue authority. The result is a system in which the same invoice can attract claims from two authorities, the definitions of where a service is provided do not match, and there is no binding referee between them. This briefing maps the maze as of July 2026 — without pretending the conflicts at its centre have been resolved, because they have not.

The five regimes

Sindh moved first. The Sindh Sales Tax on Services Act 2011 created the Sindh Revenue Board, which has since become the most litigation-tested of the provincial authorities. Punjab followed with the Punjab Sales Tax on Services Act 2012, administered by the Punjab Revenue Authority. Khyber Pakhtunkhwa established the Khyber Pakhtunkhwa Revenue Authority under its Finance Act 2013, with the regime since restated in dedicated provincial legislation [current KP statute — TO BE VERIFIED BY REVIEWING LAWYER]. Balochistan enacted the Balochistan Sales Tax on Services Act 2015, administered by the Balochistan Revenue Authority. The Islamabad Capital Territory is the odd one out: services there are taxed under the ICT (Tax on Services) Ordinance 2001, administered federally by FBR.

Each statute carries its own schedule of taxable services, its own standard and reduced rates [current rates in each province — TO BE VERIFIED BY REVIEWING LAWYER], its own exemptions, its own registration portal, and its own monthly return. The schedules have converged over the years — telecommunications, banking, insurance, construction, franchises, advertising, professional services, and IT services appear in some form almost everywhere — but the drafting differs, and a service exempt or reduced-rated in one province may be fully taxed next door.

Origin versus destination: the honest problem

The maze has a design flaw, and it is better to state it plainly than to draft around it. The provincial statutes do not agree on what connects a service to a province. Broadly, Punjab's legislation has historically emphasised origin — tax where the service is provided from — while Sindh's has emphasised destination — tax where the service is received. Each statute, read on its own terms, is capable of reaching a cross-border transaction from its own end [current statutory formulations — TO BE VERIFIED BY REVIEWING LAWYER].

Take a Lahore advertising agency running a campaign for a Karachi client. PRA can read the service as provided in Punjab. SRB can read it as received in Sindh. Both positions are arguable under the respective statutes; both authorities have, at various times, taken them; and a taxpayer caught between them faces the same value being taxed twice, with input-credit mechanisms that do not reliably operate across provincial lines [cross-province input adjustment position — TO BE VERIFIED BY REVIEWING LAWYER].

The institutional fix has been discussed for over a decade. The provinces and FBR have negotiated place-of-provision rules and coordination through bodies including the National Tax Council, and agreements have been reported on specific sectors [status of harmonisation measures — TO BE VERIFIED BY REVIEWING LAWYER]. But there is no binding cross-provincial allocation statute, and no tribunal with jurisdiction to decide that a rupee of tax belongs to Punjab rather than Sindh. Disputes are fought province by province, in each authority's own adjudication hierarchy and then the High Courts. Any adviser who tells you the conflict is solved is describing the system as it should be, not as it is.

Withholding: your customers are collectors too

Each provincial regime conscripts service recipients as collectors. Under the provincial withholding rules, prescribed classes of recipients — government departments, companies, and others — must withhold a portion of the tax when paying a service provider, particularly an unregistered one [withholding categories and portions — TO BE VERIFIED BY REVIEWING LAWYER]. Two consequences follow for a services business. Your invoicing must anticipate which province's withholding rules your customer will apply, or your receivables will arrive short and your reconciliations will not close. And your own accounts-payable function is a withholding agent in every province where your vendors' services are taxed, with its own returns to file and its own exposure for failure.

Reverse charge and services from abroad

The maze does not stop at the border. Each provincial statute reaches services received in the province from providers outside Pakistan, typically through a reverse-charge mechanism under which the recipient registers for, self-assesses, and pays the tax [scope and mechanics — TO BE VERIFIED BY REVIEWING LAWYER]. A Karachi company buying cloud services, offshore consultancy, or franchise rights from abroad may owe SRB tax on the payment even though the provider has never set foot in Pakistan. This is among the most commonly missed liabilities we see in due diligence, because nothing in the vendor's invoice signals it.

Registration strategy: deliberate, not defensive

Faced with overlapping claims, businesses drift toward one of two errors. The first is registering nowhere until a notice arrives, which converts a compliance question into a recovery proceeding with penalties and default surcharge attached. The second is registering everywhere out of caution, which multiplies monthly returns, audits, and withholding obligations without resolving the underlying allocation question. The defensible middle course is an analysis, kept in writing: where are our people and premises; where are our customers; what does each relevant statute say about services of our description; which authority's claim is strongest on those facts; and what position do we take on the overlap, disclosed how. That analysis is the core of what a tax advisory practice experienced before the provincial authorities prepares, and the recurring questions it answers are collected in our answers on tax and accounting matters.

Which authority? A first-pass decision table

This table is a triage aid, not an answer — the overlap cases turn on statutory language and current departmental practice.

Your situation	Likely authority	Watch for
Provider and customer both in one province	That province's authority	Nothing structural — check the service schedule and rate
Provider in Punjab, customer in Sindh (or the reverse)	Potentially both PRA and SRB	Double-demand risk; document the position taken [TO BE VERIFIED BY REVIEWING LAWYER]
Provider in ICT, customers nationwide	FBR under the ICT Ordinance 2001	Provincial authorities may still assert destination claims
Branches or offices in multiple provinces	Registration in each province of establishment	Apportioning revenue between registrations
Services received from outside Pakistan	Authority of the recipient's province, by reverse charge	Self-assessment obligation with no vendor prompt [TO BE VERIFIED BY REVIEWING LAWYER]
Customer is a company or government body	The provider's authority, but collection partly via customer withholding	Short receipts; reconciling withholding certificates
Exported services (customer outside Pakistan)	Zero-rating or exemption may apply, province by province [TO BE VERIFIED BY REVIEWING LAWYER]	Documentation and remittance-proof conditions

What this means for you

Map your services to provinces before the authorities do it for you: a one-page matrix of establishments, customer locations, and the statutes that plausibly apply is the cheapest insurance in this field. Where two authorities can claim the same invoice, choose a position on legal analysis, disclose it consistently in returns, and preserve the reasoning — the businesses that fare worst in cross-provincial disputes are those whose filings imply different answers in different provinces. Price the withholding rules into your receivables and build reverse charge into your vendor-payment controls, because both operate silently. Revisit the map every Finance Act season, since provincial schedules and rates move annually [current year's changes — TO BE VERIFIED BY REVIEWING LAWYER]. And treat an inter-provincial demand as a dispute to be managed from the first notice, not a bill to be paid or ignored: the record you build in the first response shapes everything that follows.
