2A & 3B mismatch

This discussion addresses a mismatch between GSTR-3B and GSTR-2A for FY 2018-19, where GSTR-3B exceeds GSTR-2A. The advice given is that if your GSTR-3B and books match, and you have valid invoices for all claimed Input Tax Credit (ITC), including from unregistered dealers, you likely don't need to pay the difference. It's recommended to keep evidence of invoices where amounts don't match GSTR-2A.
