Different business under one GST

yes it is poasible u can take gst number for different businesses coz when u regisyer for gst no

gstn portal ask about 5 hsn codes in which u will deal with

so multiple type of business can be done

Yes , you can add all 3 business to one company under One PAN

is it in the law? which section

read sec 25 (2) of registration read with rule 11

explanation- if any business have different business segments but in one state he has two option whether to take one registration for all 3 business segment or take seperate regn for all 3 business

so it depend on u u want to take burden of 3 registration or go with one registration and manage under one regn
