Provincial Sales Tax on Services: PRA, SRB and KPRA Explained

Pakistan operates a federal system in which the taxation of goods and services is split between the federal government and the provinces. While the Federal Board of Revenue collects sales tax on goods under federal law, sales tax on services falls under the jurisdiction of the provinces following the eighteenth constitutional amendment. Each province has established its own revenue authority to collect this tax, and businesses that provide services must understand which authority applies to them based on where the service is rendered or consumed.

The Punjab Revenue Authority, commonly known as PRA, administers sales tax on services in Punjab. It covers a broad range of services including telecommunications, advertising, franchise services, construction, consultancy, and many professional services. Businesses providing taxable services within Punjab must register with PRA, charge sales tax on their invoices at the applicable rate, and file monthly returns detailing their output tax collected and any input tax adjustments they are entitled to claim.

The Sindh Revenue Board, known as SRB, performs a similar function in Sindh and was in fact the first provincial authority established after the constitutional changes. SRB has its own list of taxable services, its own registration process, and its own e-portal for filing returns. Businesses operating in Karachi and other parts of Sindh that provide services such as banking, insurance, courier, restaurants, and various professional services generally need to register with SRB rather than the federal board.

The Khyber Pakhtunkhwa Revenue Authority, or KPRA, handles services taxation in Khyber Pakhtunkhwa. Its scope and rates may differ from PRA and SRB, and it maintains its own schedule of taxable services along with specific exemptions relevant to the province. Balochistan similarly has its own revenue authority for services, so a business operating across multiple provinces may need to register with more than one authority depending on where it delivers services.

A common point of confusion for businesses is determining which province has the right to tax a particular transaction, especially when the service provider is based in one province but the client or the place of service delivery is in another. Each authority has its own rules on the place of provision of service, and these rules are not always perfectly harmonised across provinces, which can occasionally lead to overlapping claims or double taxation concerns. Businesses operating nationally should review the specific place-of-supply rules of each relevant authority carefully, ideally with professional advice, to avoid registering incorrectly or under-declaring tax.

Registration with a provincial revenue authority typically requires the business to already hold a National Tax Number from FBR, along with basic documents such as CNIC copies, proof of business address, and bank account details. Once registered, the business receives a registration number specific to that authority and is expected to file periodic returns, usually monthly, declaring the value of services rendered and the tax charged to customers.

Rates of sales tax on services vary by authority and by category of service, and they are revised from time to time through provincial finance acts, so businesses should not assume a rate remains constant year after year. Some services attract reduced rates, others are subject to fixed tax regimes, and certain services may be exempt altogether depending on the province. It is important to check the current schedule of rates published by the relevant authority before invoicing clients.

Input tax adjustment rules also differ from the federal sales tax regime in some respects. A service provider registered with a provincial authority may be able to adjust input tax paid on certain purchases against its output tax liability, but the conditions for such adjustments, including invoice requirements and restrictions on specific categories of input tax, are set out in each authority's own rules. Keeping proper records of both sales and purchase invoices is essential to support any input tax claims during an audit.

Non-compliance with provincial sales tax obligations can lead to penalties, default surcharge, and in serious cases suspension of registration or legal proceedings. Businesses that fail to register despite being liable, or that under-report their taxable services, risk facing assessments and penalties from the relevant authority. Regular monthly filing, even when there is no tax liability for a particular period in some cases, helps maintain good compliance standing and keeps the business in a position to claim any refunds or adjustments it may be entitled to.

Given the complexity of dealing with multiple provincial authorities, especially for businesses that operate across more than one province, many companies choose to engage a tax consultant familiar with PRA, SRB, KPRA, and the Balochistan Revenue Authority. A consultant can help determine correct registration obligations, ensure invoices are compliant, and manage the filing calendar across different authorities, reducing the risk of missed deadlines or incorrect tax treatment that could otherwise expose the business to unnecessary penalties.
