Access to business premises requires authorized officers and mandates production of specified business records within a fixed time limit. An authorized officer appointed by the proper officer not below Joint Commissioner may inspect a registered person's business premises to examine books, documents, computers, programs, software and other relevant items for audit, scrutiny and verification. The person in charge must produce declared records, trial balance or equivalent, audited financial statements where required, cost audit and income tax audit reports if any, and other relevant records within fifteen working days or an extended period allowed; documents may be called by the authorized officer, audit party, or nominated accountants.
