<h1>GST Council Introduces New Return System; Large Taxpayers Start Monthly FORM GST ANX-1 from October 2019, Small Taxpayers Quarterly in 2020.</h1> The GST Council has introduced a new GST return system to aid taxpayers, with a transition plan starting in 2019. A prototype offline tool was shared in May 2019, allowing users to familiarize themselves with the system. From July to September 2019, taxpayers could trial the new system without affecting tax liabilities. From October 2019, large taxpayers must upload monthly FORM GST ANX-1, while small taxpayers will do so quarterly starting January 2020. FORM GSTR-1 will be replaced by FORM GST ANX-1, and FORM GSTR-3B will be phased out by January 2020, with all taxpayers filing FORM GST RET-01.
