Final answer:
AA Ltd.'s income from commission and service fees for the sales and after-sale services provided is likely taxable as Hong Kong-sourced income. The German parent company's royalty income is likely offshore-sourced and not subject to Hong Kong tax unless linked to business conducted within Hong Kong. The source of the service fee income received by AA Ltd. for facilitating manufacturer agreements will depend on where the services are rendered.
Step-by-step explanation:
The Hong Kong tax positions of AA Ltd. and its German parent company primarily involve considerations of the source of income, the nature of income, and the application of the territoriality principle of taxation. For AA Ltd., its commission-based income from distributing products in the Far East region would likely be deemed Hong Kong-sourced income, taxable under the Hong Kong Profits Tax regime because the key activities that generate this income (such as appointing sub-agents, negotiating contracts, and rendering after-sale services) are conducted in Hong Kong. Meanwhile, any royalty income collected from manufacturers in Hong Kong and China is likely to be considered offshore-sourced income for the German parent company, as the provision of manufacturing 'know-how' originates overseas. However, the service fee received by AA Ltd. from facilitating this transaction might be taxable as Hong Kong-sourced income.
It's important to note that AA Ltd.'s remittance as commission and service fees would typically be computed on a net-profit basis after allowable deductions under the Inland Revenue Ordinance (IRO). The German parent company would not be subject to Hong Kong Profits Tax on royalties received from the manufacturers in Hong Kong and China unless it carries on a business in Hong Kong, and the royalty income is derived from or arises in Hong Kong. Any training or assistance provided by AA Ltd. to manufacturers will be carefully scrutinized for their nature and whether the actual services are rendered in Hong Kong to determine the source of the service fee income.
