see as per section 13(3) of cgst act time of supply in case of URD is earliest of Date of making payment or 60 days from date of issue of invoice. So, if payment was made by GST dealer in months when service is received i.e in month of August and September then GST is required to be paid under reverse charge because notification of removal of reverse charge on URD is applicable from 13th October 2017 and if no payment was made earlier then there is no applicability of GST.
