Registered persons must maintain extensive records under the GST Act and draft record rules, including records of production, supply of goods and services, input tax credit, output tax, stock, and financial accounts. Records must be maintained separately for each business activity and place of registration. Additional requirements apply to transporters, warehouse owners, agents, manufacturers, service providers, and contractors. Persons with over Rs. 1 crore annual turnover must also submit audited accounts. Electronic records require digital authentication and backup, and taxpayers must provide an audit trail on demand. Non-compliance could harm a business's GST compliance rating.
