GST audits include tax authority audits, special audits by chartered/cost accountants with commissioner approval, and turnover-based audits.

Three audit mechanisms exist under GST: audit by tax authorities by an authorized officer (no turnover limit), special audit by a chartered/cost accountant appointed by the Commissioner after prior approval and requisite officer order, and turnover-based audit by a chartered/cost accountant when aggregate turnover exceeds the prescribed quantum, with the statutory turnover provision omitted effective 1 August 2021.
