GST return is a form that which the Tax payer registered under GST is required to file with Authorities which will contain all the details of your sales, purchases, tax collected on sales (output tax), and tax paid on purchases (input tax). Once you file GST returns, you will need to pay the resulting tax liability (money that you owe the government).
Regular businesses with an annual aggregate revenue of more than Rs. 5 crore (as well as taxpayers who did not choose the QRMP plan) are required to file two monthly returns and one yearly return under the GST system. Each year, this results in 25 returns.
The QRMP plan allows taxpayers with a revenue of up to Rs. 5 crore to file returns. Each year, QRMP filers must submit nine GSTR files, which include four GSTR-1 and three GSTR-3B forms as well as an annual return. It should be noted that even if QRMP filers submit their returns on a quarterly basis, they must pay tax on a monthly basis.
There are also separate statements/returns required to be filed in special cases such as composition dealers where the number of GSTR filings is 5 each year (4 statement-cum-challans in CMP-08 and 1 annual return GSTR-4).
