- This applies to all GST returns, including GSTR‑1, GSTR‑3B, GSTR‑4, GSTR‑5, GSTR‑5A, GSTR‑6, GSTR‑7, GSTR‑8, and GSTR‑9.
- This change particularly affects businesses that usually catch up on older returns at year-end because delayed filing will no longer be possible. Tip: Don’t let old returns pile up file them before the window closes.
- Tip: Don’t let old returns pile up file them before the window closes.
2. GSTR‑3B Is Locked After Filing
- Once you file GSTR‑3B, the liability is locked. Any corrections need to go through GSTR‑1A.

Common Monthly Returns
Before we get to discuss the return filing schedule for each month, let us discuss some common returns you would be filing every month.
– GSTR-1: This return is used to report details of outward supplies (sales) made during the month. The due date for the same is the 11th of the following month.
For detailed return formats and filing process, refer to the official GST return documentation.
– GSTR-3B: This return is a summary return for declaring tax liabilities and claiming input tax credit. The due date for the same is the 20th of the following month.
– GSTR-5: This GST return is for non-resident taxable persons to report their business transactions in India. The due date for the same is the 13th of the following month.
– GSTR-5A: A GST return for reporting outward supplies and tax collected by Online Information and Database Access or Retrieval (OIDAR) services. The due date for this is the 20th of the following month.
– GSTR-6: This one is for Input Service Distributors (ISD) to distribute input tax credits among their branches. The due date for the same is the 13th of the following month.
– GSTR-7: This return is for entities required to deduct tax at source (TDS) under GST. You need to file this on the 10th of every month.
– GSTR-8: GSTR-8 is for e-commerce operators to report the tax collected at source (TCS) from supplies made through their platforms. This is also filed on the 10th of every month.
Common Quarterly Returns
In addition to certain monthly returns, there are also various quarterly returns filed on different dates of different months:
– GSTR-1: For businesses with an aggregate turnover above 5 crore rupees, it is mandatory to file a monthly GSTR-1 return. However, for businesses with turnover up to 5 cr, there is an option to opt for the QRMP scheme and file a quarterly GSTR-1 return. This is done on the 13th of the month following a particular quarter.
– GSTR- 3B: Like GSTR-1, GSTR-3B also has a special provision to file quarterly reports for businesses with turnover up to 5cr. These quarterly returns are filed on the 24th of the month following a particular quarter.
Common Yearly Returns
For annual returns, there is a return specific to composition scheme taxpayers and another one applicable to all with 5cr+ turnover.
– GSTR-4: GSTR-4 replaced GSTR-9A as an annual return to be filed by those under the composition scheme. Now, this is filed on 30th April following every financial year.
– GSTR-9/9C: GSTR 9/9C are annual return and reconciliation statements filed by regular taxpayers. These are a consolidation of all monthly and quarterly returns filed in a financial year. These returns are paid on the 31st of December of the year following the relevant financial year.
