Under Pakistani law, there is no universal “turnover only” threshold that automatically exempts all businesses from sales tax (GST) registration. For many categories (manufacturers, importers, wholesalers, distributors, large retailers), registration is mandatory regardless of turnover
Some small businesses — e.g. “cottage industry” manufacturers or small retailers — may be exempt from mandatory registration if they meet specific criteria (turnover below a certain level, low utility bills, noncommercial scale).
In addition, any importer, wholesaler/distributor, large retailer (“Tier1” retailer), exporter, or business supplying taxable goods/services under provincial/federal laws must register.
