GST Applicability in case of 2 seperate business on proprietor

This discussion clarifies GST applicability when a proprietor runs two separate businesses, IT services and cleaning services, with a combined annual turnover below the threshold. Although GST registration was voluntarily taken for the cleaning business, the proprietor questioned whether GST should be charged on IT services. The consensus is that if the combined turnover across all businesses under the same PAN does not exceed the Rs. 20 lakh threshold and inter-state supplies are not made, separate GST registration for each business might not be mandatory. However, once GST registration is taken for one business, all services under that PAN may be subject to GST if the aggregate turnover exceeds the limit.
