Types of GST Returns and Due dates

GSTR-1 is the return to be furnished for reporting details of all outward supplies of goods and services made. In other words, it contains the invoices and debit-credit notes raised on the sales transactions for a tax period. GSTR-1 is to be filed by all normal taxpayers who are registered under GST, including casual taxable persons.
Any amendments to sales invoices made, even pertaining to previous tax periods, should be reported in the GSTR-1 return by all the suppliers or sellers.
The filing frequency of GSTR-1 is currently as follows:
(a) Monthly, by 11th of every month- If the business either has an annual aggregate turnover of more than Rs.5 crore or has not opted into the QRMP scheme.
(b) Quarterly, by 13th of the month following every quarter- If the business has opted into the QRMP scheme.

GSTR-2A is a view-only dynamic GST return relevant for the recipient or buyer of goods and services. It contains the details of all inward supplies of goods and services i.e., purchases made from GST registered suppliers during a tax period. The data is auto-populated based on data filed by the corresponding suppliers in their GSTR-1 returns. Further, data filed in the Invoice Furnishing Facility (IFF) by the QRMP taxpayer, also get auto-filled.
Since GSTR-2A is a read-only return, no action can be taken in it. However, it is referred by the buyers to claim an accurate Input Tax Credit (ITC) for every financial year, across multiple tax periods. In case any invoice is missing, the buyer can communicate with the seller to upload it in their GSTR-1 on a timely basis.
It was used frequently for claiming ITC for every tax period until August 2020. Thereafter, the buyers must mostly refer to GSTR-2B, static return, to claim the input tax credit for every tax period.

GSTR-2B is again a view-only static GST return important for the recipient or buyer of goods and services. It is available every month, starting in August 2020 and contains constant ITC data for a period whenever checked back.
ITC details will be covered from the date of filing GSTR-1 for the preceding month (M-1) up to the date of filing GSTR-1 for the current month (M). The return is made available on the 12th of every month, giving sufficient time before filing GSTR-3B, where the ITC is declared. GSTR-2B provides action to be taken against every invoice reported, such as to be reversed, ineligible, subject to reverse charge, references to the table numbers in GSTR-3B.

GSTR-2 is currently a suspended GST return, that applied to registered buyers to report the inward supplies of goods and services, i.e. the purchases made during a tax period.
The details in the GSTR-2 return had to be auto-populated from the GSTR-2A. Unlike GSTR-2A, the GSTR-2 return can be edited. GSTR-2 is to be filed by all normal taxpayers registered under GST. However, the filing of the same has been suspended ever since September 2017.

GSTR-3 is again currently a suspended GST return. It was a monthly summary return for furnishing summarized details of all outward supplies made, inward supplies received and input tax credit claimed, along with details of the tax liability and taxes paid.
This return would have got auto-generated on the basis of the GSTR-1 and GSTR-2 returns filed. GSTR-3 is to be filed by all normal taxpayers registered under GST, however, the filing of the same has been suspended ever since September 2017.

GSTR-3B is a monthly self-declaration to be filed, for furnishing summarised details of all outward supplies made, input tax credit claimed, tax liability ascertained and taxes paid.
GSTR-3B is to be filed by all normal taxpayers registered under GST. The sales and input tax credit details must be reconciled with GSTR-1 and GSTR-2B every tax period before filing GSTR-3B. GST reconciliation is crucial to identify mismatches in data, that may lead to GST notices in future or suspension of GST registration as well.
The filing frequency of GSTR-3B is currently as follows:
(a) Monthly, 20th* of every month- For taxpayers with an aggregate turnover in the previous financial year of more than Rs.5 crore or have been otherwise eligible but still opted out of the QRMP scheme.
(b) Quarterly, 22nd of the month following the quarter for ‘X’** category of States and 24th of the month following the quarter for ‘Y’** category of States- For the taxpayers with aggregate turnover equal to or below Rs 5 crore, eligible and remain opted into the QRMP scheme.

(ii) Was 20th of every month till December 2019.

GSTR-4 is the annual return that was to be filed by the composition taxable persons under GST, by 30th April of the year following the relevant financial year. It has replaced the erstwhile GSTR-9A (annual return) from FY 2019-20 onwards.
Prior to FY 2019-20, this return had to be filed on a quarterly basis. Thereafter, a simple challan in form CMP-08 filed by 18th of the month succeeding every quarter replaced it.
The composition scheme is a system in which taxpayers dealing with goods and having a turnover up to Rs.1.5 crores can opt into and pay taxes at a fixed rate on the turnover declared. Further, the service providers can avail a similar scheme CGST (Rate) Notification 2/2019 dated 7th March 2019 if turnover is up to Rs.50 lakh.

GSTR-5 is the return to be filed by non-resident foreign taxpayers, who are registered under GST and carry out business transactions in India.

GSTR-5A refers to a summary return for reporting the outward taxable supplies and tax payable by Online Information and Database Access or Retrieval Services (OIDAR) provider under GST.

It contains the details of all outward supplies made, inward supplies received during the relevant financial year under different tax heads i.e. CGST, SGST & IGST and a summary value of supplies reported under every HSN code, along with details of taxes payable and paid.
It is a consolidation of all the monthly or quarterly returns (GSTR-1, GSTR-2A, GSTR-3B) filed during that financial year. GSTR-9 is required to be filed by all taxpayers registered under GST.
However, there are few exceptions such as taxpayers who have opted for the composition scheme, casual taxable persons, input service distributors, non-resident taxable persons and persons paying TDS under section 51 of the CGST Act.
Note:  As per the CGST notification no. 47/2019, later amended, the annual return under GST for taxpayers having an aggregate turnover that does not exceed Rs.2 crore has been made optional for FY 2017-18, FY 2018-19 and FY 2019-20.

GSTR-9A is currently a suspended annual return earlier required to be filed by composition taxpayers. It had a consolidation of all the quarterly returns filed during that financial year.
Ever since GSTR-4 (annual return) was introduced from FY 2019-20, this return stands scrapped. Prior to that, GSTR-9A filing for composition taxpayers had been waived off for FY 2017-18 and FY 2018-19.

GSTR-9C is the reconciliation statement to be filed by all taxpayers registered under GST whose turnover exceeds Rs.2 crore in a financial year, as per the GST law.
It must be certified by a Chartered Accountant/Cost & Management Accountant after conducting a thorough GST audit of the books of accounts and comparing the figures with the GSTR-9.
The deadline to file this statement is the same as the due date prescribed for GSTR-9, i.e., 31st December of the year following the relevant financial year.
GSTR-9C is to be filed for every GSTIN, hence, one PAN can have multiple GSTR-9C forms being filed.
As per the Union Budget 2021 outcome, the GST audit requirement by professionals such as CAs and CMAs has been removed from the GST law. Sections 35 and 44 were amended for this but yet to be notified by CBIC. Accordingly, GSTR-9 needs to be filed on the GST portal by taxpayers on a self-certification basis, completely removing the requirement for GSTR-9C. However, the financial year and date of applicability of this removal are yet to be clarified by the government.
Note:As per the CBIC notification 16/2020, which was further amended, GSTR-9C is waived off for the taxpayers with an aggregate turnover of more than Rs.5 crore for the financial year 2018-19 and 2019-20.
