Mismatch in GST of 2018-19

Hi Dhruv,

Thanks for your prompt response. But what about Clause (d) of Sec 16(2) of CGST Act. It puts up a condition that "he has furnished the return under section 39 [every taxable person is required to file electronic return every month as per section 39 of CGST Act]."

Isn't the intention of the act here was that supplier should upload the invoice in his GSTR1? 

What's your opinion?

Even if the time is passed, Y can amend the invoice with X1 GSTIN. Since X1 has already taken ITC no action required from X1 side. For X2 what you have done is correct so no action required from X2 too

Hi Bhavika,

Thanks for your response. Yes, X1 & X2 both are correct on their part. But How Y can amend it with X1's GSTIN now?

Because when Y tries to amend the details in his current GSTR -1, the drop-down shows only two options, 2019-20 & 2020-21, and not 2018-19.
