gst audit mandatory ?

As per Sec. 35(5) of the CGST Act, Where an organization or an entity has multiple branches registered under GST in different states/UTs, the total aggregate turnover of all such branches is considered while calculating the threshold limit of Rs. 2 crores.So, if the cumulative turnover of all the branches exceeds Rs. 2 crores, then the GST audit is applicable to each of these branches, irrespective of whether the turnover of a particular branch is less than the threshold.In such cases, one can appoint either one dedicated auditor for all branches or separate auditor for each branch.
