How to Amend B2C Invoice to B2B in GSTR1 :

As we are aware that September 2018 is last month to avail GST credit for F.Y 2017-18A common query from taxpayers is what happens if a B2B Invoice is recorded as B2C. This can happen because of any of the following reasons:

1.) Purchaser has not submitted GSTIN .

2.) Purchaser has submitted GSTIN, but it is not recorded in Accounting System

3.) Purchaser has applied for GST Registration, but has still not received GSTIN.

Let’s Assume in the Month of March 2018 B2B invoice has shown to B2C. Total Invoice value was  1180, Taxable Amount was Rs. 1000 and GST 180. Later on we came to know that invoice shown in March 2018 was Actually B2B invoice but by any reason it has been shown to B2C. Therefore we need to amend that B2C invoice to B2B in coming month GSTR1. We can amend that in Oct Month GSTR-1 as well but it is advisable to Amend in Sep 2018 Return so that your customer can also take credit of the invoice otherwise in Oct’2018 return your customer will  not be able to take credit as it pertains to F.Y 2017-18.
