Notes
- Monthly TDS deposit dates above assume non-Government deductors. Government deductors (book entries) follow Rule 30(2A) — typically same day for government deductors paying without challan.
- GSTR-3B due dates assume **monthly filing**. QRMP filers (AATO ≤ Rs. 5 cr) follow the quarterly cycle — 22nd / 24th of month following the quarter for Category-X / Y states respectively.
- The Department may extend any due date by notification. Always verify the current position on the respective Government portal before filing.
