Exemptions: Many specific tables in GSTR-9 and GSTR-9C (notably HSN summaries in GSTR-9 and turnover/ITC reconciliation tables in GSTR-9C) were made optional for FY 2020-21 to simplify the filing process.
Certification: CA/CMA certification is no longer required for GSTR-9C. The return must be self-certified by the taxpayer.
