Yes, whatever your income level or whether a profit is generated or not, every company registered in Hong Kong must perform an audit. The accounting can be set up internally. Nevertheless, the audit should be performed by an independent auditor operating under the Hong Kong company ordinance.
Your bank must be solicited as well in order to get what is called a “bank confirmation”. Once the audit is performed, the tax return can be sent to the IRD to declare your profit and potentially calculated profit tax amount.
