CMP-08 must be filed by all taxpayers registered under the GST composition scheme, including service providers. It is used to declare and pay self-assessed tax every quarter and must be submitted by the 18th of the month following each quarter.
The GSTN enabled the CMP-08 filing facility on 29 July 2019. This form replaced the earlier quarterly GSTR-4 from FY 2019-20 onwards. Instead, composition taxpayers are now required to file GSTR-4 annually, starting from April 2020 for the financial year 2019-20. (as per Central Tax (Rate) Notification No. 2/2019 dated 7 March 2019).
