We are Rajasthan Based Pvt Ltd Company, And providing services by way of Installation, erection and commissioning in various states of the India and having centralized office in Rajasthan from where all important decisions are taken and billing and payment are done. Further we also provide some services to other companies in rajsthan by renting them machinery and equipments and those companies are not registered in rajasthan .

My questions are,

1. Are we liable to take GST registration in each state or not ?

2. Should we show IGST or CGST & SGST for service provided to other state's companies in Rajsthan ?

3. We also provided services to Jammu and Kashmir, whether GST is applicable or not ?
