An Individual Mr. X has a proprietorship M/s ABC. this firm is registered under service tax. now Mr. X is going to start another proprietorship M/s XYZ. question is that whether Mr. X has to add this new proprietorship with old service tax registration no. or apply for new registration no.? because the PAN no. is same for both the firms.
