department issued notice and asking to reverse or pay the ITC claimed for the months falling in FY 2018-19, filed after 21.10.2019 is there any way to come out of this situation using any other section or rules or notification references
Yes you can claim ...... but there are few cases in which supplier is found to be defaulter or done fraud , in such situation the Receptient is liable to reverse the ITC . Refer Section 155 of CGST Act
