Security requirement: Commissioner may demand or adjust security for VAT registration, refunds, de sealing and tax compliance. The Commissioner may require a person or prescribed class to furnish security as a condition of registration, continuance, tax realisation, refunds or de-sealing, in the prescribed amount, manner and time, including liabilities under this Act and the Central Sales Tax Act. The Commissioner may vary, increase, reduce or waive security based on business nature and size, likely liability, creditworthiness, nature of security and other relevant matters. Surety bonds must be replaced if a surety dies, becomes insolvent, or the surety-dealer's registration is cancelled or business closed. The Commissioner may forfeit security and require replenishment or fresh security where it is forfeited or insufficient.
