The GSTR-3B due date for monthly filers is the 20th of the next month (for example, June 2026 GSTR-3B is due by 20 July 2026) \u2014 this date is the same all over India. For QRMP (quarterly) filers, GSTR-3B is due 22nd or 24th of the month after the quarter, depending on your state \u2014 22nd for most southern\/western states and 24th for most northern\/eastern states. <\/p>\n\n\n\n
If you file GST returns late, you may have to pay a daily late fee and interest on unpaid tax. You also need to clear the previous GSTR-3B before filing the next one. From July 2025, a return cannot be filed after 3 years from its original due date. Always check gst.gov.in<\/a> for the latest filing date. <\/p>\n\n\n\n Do you want to know your exact GSTR-3B due date and avoid late fees?
