Hong Kong's basis of taxation on profits from businesses
Hong Kong adopts a territorial basis for taxing profits derived from a trade, profession, or business carried on in Hong Kong. Profits Tax is only charged on profits which arise in or are derived from Hong Kong. In simple terms this means that a person who carries on a business in Hong Kong but derives profits from another place is not required to pay tax in Hong Kong on those profits.
Many places levy tax on a different basis. Unlike Hong Kong, they tax the world-wide profits of a business, including profits derived from an offshore source.
