I am a service tax assessee having a partnership firm providing HR consultancy. My last revenue generation had happened in 2015-16 and the amount was Rs 10000/-. After that I have stopped doing my business as I have taken a job. Though I have stopped doing my business I have been dilligently filing my ST3 till H1 2016-17 as I have a service tax liability of more than a lac rupees which I could not deposit. My question is that do I have to migrate to GST or keep filing my zero returns under service tax until I clear my service tax liability.
