A recent Federal Constitutional Court order in Mirpurkhas Sugar Mills Limited v Province of Sindh has attracted considerable attention over the scope of provincial sales tax on services, particularly where services are supplied by non-residents or involve activities extending beyond one province. The Court declined leave against proceedings requiring the taxpayer to respond to a show-cause notice and also found section 3(2) of the Sindh Sales Tax on Services Act, 2011 to be intra vires in the context before it.
The significance of the order, however, should be understood carefully. The material under discussion argues that the FCC did not comprehensively determine the wider constitutional question of extra-territorial provincial taxation, including where a service is performed, consumed or economically connected with more than one province. Articles 141 and 151 of the Constitution, earlier Supreme Court jurisprudence concerning territorial legislative competence, and the risk of overlapping provincial claims remain important considerations in determining the proper taxing jurisdiction.
For banks, telecom companies, digital platforms and businesses operating nationwide, the issue has major practical implications. Where Sindh, Punjab and other provincial authorities apply different concepts such as origination, receipt, destination or consumption, the same integrated service may potentially face overlapping tax claims. The broader policy requirement is therefore a harmonised place-of-supply framework, clear apportionment principles and an effective reciprocal adjustment mechanism so that legitimate provincial revenue collection does not translate into multiple taxation of the same transaction.
