<h1>India Revises Rule 61: Staggered GSTR-3B Filing Starts January 2021 for Monthly and Quarterly Filers Across Regions.</h1> The Government of India has revised Rule 61 of the Central Goods and Services Tax Rules, 2017, to implement staggered filing of Form GSTR-3B starting January 2021. Monthly filers across all states and union territories must submit by the 20th of the following month. Quarterly filers in specific states and union territories, including Chhattisgarh, Maharashtra, and Kerala, have a deadline of the 22nd of the month following the quarter, while others, such as Himachal Pradesh and West Bengal, have until the 24th. This change aims to streamline the filing process for registered businesses.
