Two returns carry almost all the work. GSTR-1 reports what you sold and is due on the 11th of the following month. GSTR-3B carries the tax payment and is due on the 20th.
The common misreading is treating GSTR-1 as optional when there is no tax to pay. It is not optional, and it is the return that decides whether your customer gets their input tax credit. Miss it and you damage them, not just yourself.
Which GST return do you file, and when?
| Form | Who files it | Frequency | Due date | Rule or section |
|---|---|---|---|---|
| GSTR-1 | Normal taxpayers | Monthly | 11th of the following month | Section 37, rule 59 |
| GSTR-1 (quarterly) | QRMP taxpayers | Quarterly | 13th of the month after the quarter | Section 37, rule 59 |
| Invoice Furnishing Facility | QRMP taxpayers, optional | First two months of a quarter | Up to ₹50,00,000 of value each month | Rule 59(2) |
| GSTR-3B | Normal taxpayers | Monthly | 20th of the following month | Rule 61(1)(i) |
| GSTR-3B (quarterly) | QRMP taxpayers | Quarterly | 22nd or 24th, depending on your state | Rule 61(1)(ii) |
| GST PMT-06 | QRMP taxpayers | First two months of a quarter | 25th of the following month | Rule 61(3) |
| GST CMP-08 | Composition taxpayers | Quarterly | 18th of the month after the quarter | Rule 62(1)(i) |
| GSTR-4 | Composition taxpayers | Annual | 30 June following the financial year | Rule 62, proviso |
| GSTR-5 | Non-resident taxable persons | Monthly | As prescribed for the form | Section 39(5) |
| GSTR-5A | OIDAR service providers outside India | Monthly | As prescribed for the form | Section 39 |
| GSTR-6 | Input service distributors | Monthly | As prescribed for the form | Section 39(4) |
| GSTR-7 | Persons deducting tax at source | Monthly | As prescribed for the form | Section 39(3) |
| GSTR-8 | E-commerce operators collecting tax | Monthly | As prescribed for the form | Section 52 |
| GSTR-9 | Normal taxpayers | Annual | 31 December following the financial year | Section 44, rule 80(1) |
| GSTR-9C | Turnover above ₹5,00,00,000 | Annual | 31 December, with GSTR-9 | Rule 80(3) |
Is your quarterly GSTR-3B due on the 22nd or the 24th?
It depends on where your principal place of business is. Rule 61 splits the country into two groups.
| Due date | States and union territories |
|---|---|
| 22nd of the month after the quarter | Chhattisgarh, Madhya Pradesh, Gujarat, Maharashtra, Karnataka, Goa, Kerala, Tamil Nadu, Telangana, Andhra Pradesh, Daman and Diu, Dadra and Nagar Haveli, Puducherry, Andaman and Nicobar Islands, Lakshadweep |
| 24th of the month after the quarter | Himachal Pradesh, Punjab, Uttarakhand, Haryana, Rajasthan, Uttar Pradesh, Bihar, Sikkim, Arunachal Pradesh, Nagaland, Manipur, Mizoram, Tripura, Meghalaya, Assam, West Bengal, Jharkhand, Odisha, Jammu and Kashmir, Ladakh, Chandigarh, Delhi |
Note the trap in the QRMP scheme. The return is quarterly, but the tax is not. You still deposit tax in GST PMT-06 by the 25th for each of the first two months of the quarter.
What happens if you file late?
Section 47 sets a late fee of ₹100 a day under the CGST Act, up to ₹5,000. State GST law mirrors it, so the practical figure is double that.
The annual return is treated differently. The late fee there is ₹100 a day, capped at a quarter of one per cent of your turnover in the state or union territory.
Interest on unpaid tax runs separately from the late fee. The two are not alternatives.
Can you file an old return you missed?
Not indefinitely. A registered person cannot furnish the annual return for a financial year after three years from its due date. Section 44(2) says so plainly.
The government can relax that by notification for a class of taxpayers, but you should not plan around a relaxation that may never come.
The practical rule is simple. A return more than three years overdue may be permanently closed to you, along with any credit that depended on it.
How do you keep this manageable?
Reconcile monthly, not annually. Your purchase register against GSTR-2B, every month, is what protects your input tax credit.
Let the books generate the return rather than the other way round. Our page on accounting software covers what to look for. If you are not yet registered, start with GST registration.

Common questions
What is the due date for GSTR-1 and GSTR-3B?
For monthly filers, GSTR-1 is due on the 11th of the succeeding month and GSTR-3B on the 20th. Quarterly filers under QRMP file GSTR-1 by the 13th of the month after the quarter, and GSTR-3B by the 22nd or 24th depending on the state where their principal place of business is.
Who has to file GSTR-9C?
Rule 80(3) requires a self-certified reconciliation statement in GSTR-9C from every registered person whose aggregate turnover in the financial year exceeds ₹5,00,00,000. It is filed along with the annual return in GSTR-9, on or before 31 December following the end of that financial year.
What is the late fee for filing GST returns late?
Section 47 provides ₹100 a day under the CGST Act, subject to a maximum of ₹5,000. State GST law imposes a matching amount, so the effective fee is twice the CGST figure. For the annual return the cap is a quarter of one per cent of your turnover in that state or union territory.
Can I still file a GST return from three years ago?
Probably not. Section 44(2) bars furnishing an annual return more than three years after its due date. The government retains a power to allow it by notification, but that is a concession, not a right. Treat the three-year mark as a hard deadline.
Do I have to file GST returns if I had no sales?
Yes. A nil return is still a return. Skipping it attracts the late fee under section 47 and can block your next filing, because returns must generally be filed in order. Nil filing is quick and can be done by SMS for eligible taxpayers.
