GST returns must be filed monthly or quarterly depending on the taxpayer category.
Key monthly returns include GSTR-1 (outward supplies) due by the 11th of the next month and GSTR-3B (summary return) due by the 20th of the next month.
Quarterly return filers must file GSTR-1 by the 13th and GSTR-3B by the 22nd of the month following the quarter.
Late filing attracts interest and penalties, affecting compliance status.
Non-filing beyond a specified period can lead to cancellation of GST registration, but reinstatement procedures are available.
Stay compliant by noting deadlines and filing timely to avoid penalties or disruptions in business.
