Sir,
In 2018 July We have filed the GSTR -1 and GSTRB ,we didn't showed 2 out put sales invoices in GSTR-1 (Mistakenly we didn't showed) but In GSTRB-3B we have calculated 2 invoices and paid tax to Government against same invoices. we have not uploaded the 2 invoices of Party ,but Party claimed the input against invoice.
In this case what should we do for that invoice , Is this possible to amend the 2018 July invoice in March 2021.
We paid tax to against invoice for same invoices.
