GST return due dates depend on the type of taxpayer and filing scheme.
Businesses should distinguish between monthly filing and quarterly filing under QRMP.
For example, the GST Portal's QRMP guidance states that quarterly GSTR-1 is generally due on the 13th of the month following the quarter, while GSTR-3B generally follows different due dates based on the state or category of taxpayer.
Why businesses should track due dates
Missing a return deadline can result in:
- Late fees
- Interest on applicable delayed tax payments
- Compliance complications
- Problems with subsequent filing
Best practice
Don't wait until the due date.
A better monthly GST workflow is:
Sales data → Purchase data → ITC reconciliation → GST review → Return preparation → Filing → Records
Businesses should always verify the current due date displayed on the GST Portal because government notifications can modify deadlines.
