A taxpayer (recipient) has an invoice of oct 2017 which was claimed in GSTR-3B during the FY 2017-18. But the supplier filed GSTR-1 of that tax period of FY 2017-18 in June 2019. The due date to claim ITC for FY 2017-18 is Apr 2019. Will the taxpayer (recipient) have to reverse the ITC of that invoice now ???
