Access to business premises enables authorised tax officers to inspect records and compel production to safeguard revenue. Officers authorised by the proper officer not below Joint Commissioner may access any registered person's business premises to inspect books, documents, computers, programs and other things for audit, scrutiny and revenue safeguards, and may deploy an audit party or nominated chartered/cost accountant. The person in charge must produce declared accounting records, trial balance, audited annual accounts where required, cost audit reports, income tax audit reports and other relevant records for scrutiny within fifteen working days of demand, unless an extension is permitted by the inspecting authority.
