CMP-08 filing must be done by all composition taxpayers (including service providers opting for composition scheme under Central Tax (Rate) Notification number 2/2019 dated 7 March 2019). The GSTN has, after much delay, opened the facility to declare and submit GST liability in CMP-08 (payment of self-assessed tax) for all the composition dealers on 29 July 2019. The composition dealers have to pay tax in CMP-08 challan-cum-statement every quarter by the 18th of the month following the quarter. The form replaces GSTR-4 with effect from FY 2019-2020. In turn, composition dealers must file GSTR-4 annually from April 2020 for the annual year 2019-2020.
