Hong Kong Shipping & Maritime Tax — Expert Advisory

Under s.23B of the IRO, profits from the operation of ships outside Hong Kong waters are exempt from profits tax, provided the ship is registered under the Merchant Shipping (Registration) Ordinance or the operator is carrying on business in HK. Income from ships operating exclusively within HK waters (e.g., harbour ferries) is taxable. The key is the distinction between HK-waters and international operations.

Hong Kong seafarers are subject to salaries tax on their total income, but they can claim a time-apportionment deduction for days spent outside HK on sea service. If a seafarer spends 200 days at sea outside HK in a 365-day year, approximately 54.8% of their income is excluded from HK salaries tax. Proper voyage logs and sea service certificates are essential documentation.

Ship management fees received by a Hong Kong management company for providing technical or crew management services are taxable in HK as the services are rendered from HK. These are distinct from shipping income and do not qualify for the s.23B exemption. Careful structuring is needed if both management and shipping operations are conducted from HK.

Yes, vessels registered in HK and used in a qualifying trade are plant & machinery for capital allowance purposes under Part VI of the IRO. Initial allowances (60%) and annual allowances (10-30% reducing balance) are available. However, for vessels whose income is exempt under s.23B, the capital allowances can only be offset against taxable shipping income, not exempt shipping income.

Yes. Commissions earned by HK ship agents for arranging port calls, cargo handling, and husbandry services for vessels in HK waters are Hong Kong-source income and fully taxable under profits tax. This applies even if the ship owner is non-resident. Port agency income cannot benefit from the s.23B shipping income exemption.
