GSTR-9 is the annual return capturing yearly purchases, sales, ITC, refunds, and demands, while GSTR-9C is a reconciliation statement applicable where aggregate turnover exceeds the prescribed threshold, reconciling books with GST returns. Common reporting mistakes include mismatch of ITC across years, incorrect reversal or reclaim reporting, differences between GSTR-1, GSTR-3B, and books, wrong RCM disclosure, errors in exempt/NIL supplies, and incorrect tax payment reporting.

GSTR-9 is the annual return capturing yearly purchases, sales, ITC, refunds, and demands, while GSTR-9C is a reconciliation statement applicable where aggregate turnover exceeds the prescribed threshold, reconciling books with GST returns. Common reporting mistakes include mismatch of ITC across years, incorrect reversal or reclaim reporting, differences between GSTR-1, GSTR-3B, and books, wrong RCM disclosure, errors in exempt/NIL supplies, and incorrect tax payment reporting. ITC claimed, reversed, and reclaimed in the same financial year must be carefully split across Tables 6, 7, and 6H to avoid duplication caused by auto-population from GSTR-3B. ITC of a previous year claimed in the current year is reported separately in Table 6A1, but ITC reclaimed due to Rule 37/37A follows different reporting logic and should not be mixed with normal reclaims. ITC claimed in a later year for invoices or imports relating to earlier years is reflected in Table 8C or newly inserted import-related rows, ensuring no mismatch between eligible and claimed credit. Reversal of earlier-year ITC made in the current year is not reported in GSTR-9 of the current year, as Table 7 captures only reversals relating to the same financial year. In GSTR-9C, differences in net ITC reconciliation may arise due to timing differences; such mismatches should be properly explained in the reconciliation difference table to avoid audit objections. Table 9 of GSTR-9 reflects only tax actually paid through GSTR-3B during the year; interest, late fees, penalties, and post-annual-return DRC-03 payments must not be included.
