GST Return Filling
A GST return is a document containing details of all income/sales and/or expenses/purchases that a GST-registered taxpayer (every GSTIN) is required to file with the tax administrative authorities. This is used by tax authorities to calculate net tax liability.

Under GST, a registered dealer has to file GST returns that broadly include:

Purchases
Sales
Output GST (On sales)
Input tax credit (GST paid on purchases)
How many returns are there under GST?

There are 13 returns under GST. They are the GSTR-1, GSTR-3B, GSTR-4, GSTR-5, GSTR-5A, GSTR-6, GSTR-7, GSTR-8, GSTR-9, GSTR-10, GSTR-11, CMP-08, and ITC-04. However, all returns do not apply to all taxpayers. Taxpayers file returns based on the type of taxpayer/type of registration obtained. Eligible taxpayers, i.e. with a turnover exceeding Rs.5 crore are also required to also file a self-certified reconciliation statement in Form GSTR-9C.Besides the GST returns that are required to be filed, there are statements of input tax credit available to taxpayers, namely GSTR-2A (dynamic) and GSTR-2B (static). There is also an Invoice Furnishing Facility (IFF) available to small taxpayers who are registered under the QRMP scheme to furnish their Business to Business (B2B) sales for the first two months of the quarter. These small taxpayers will still need to pay taxes on a monthly basis using Form PMT-06
