This discussion clarifies that it is indeed possible for a GST-registered individual with one GSTIN to operate multiple businesses within the same state, even if they are in different sectors like automotive and electrical. Importantly, you can use different business names for each venture under the same GST number.
Can a GST registered person with one GSTIN can do multiple business in same state. Like: for Ex: He has already a Automobile business and now he is willing to do Electrical business. can it be possible to do both the business on same GST number? if yes should I use the same business name for both?.
