GST audit is a reconciliation statement of GSTR9 with an audited annual account. This statement includes sale, purchase, input, output, total tax paid, demand, and refund of the whole financial year.
In the GST audit, certification required by a CA/CMA has been removed from FY 2020-21 onwards.
A taxpayer whose total turnover exceeds RS 5 Crore will require self-certification in form 9C from financial 2020-21 onwards.
So GSTR 9C was modified according to applicable changes from the GST council meeting.
Also, the GSTR 9C Turnover limit increased from RS 2 Crore to RS 5 Crore.
GSTR9 is an annual return filed by assessment before 31st December 2022. This return includes a summary of the financial year of GSTR1 and GSTR3B, and GSTR2B details, with books of accounts. If any difference occurs with books of accounts, then this difference adjusts by GSTR9.
