Hong Kong has a territorial basis of taxation. Only local-source trading, property or employment income is taxed, and investment income is not taxed. The corporate profits tax rate is 16.5%; there is no capital gains tax, no withholding tax, no sales taxes, no VAT, no annual net worth taxes and no accumulated earnings taxes on companies which retain earnings rather than distribute them.
There are a number of full or partial exemptions from profits tax:
Personal taxation is among the lowest in the world at around 15% on "assessabel income" after the deductions but before allowances or at progressive rates levied on "assessable income" after the deductions and allowances. From the tax year 2008/2009 these progressive tax rates are:
Nil to HKD40,000 - 2%
HKD40,000 to HKD 80,000 - 7%
HKD80,000 to HKD 120,000 - 12%
HKD120,000 upwards - 17%
Individuals pay no tax on investment income or capital gains, whether resident or not.
There are no special rules for foreign employees of Hong Kong businesses; the territorial principle governs salaries tax with the consequence that salaries tax is only levied on income "arising in or derived from a Hong Kong employment". The definition of income includes wages, salaries, bonuses, commissions, payments by the employer into a pension fund for the employee and gratuities. It does not include either a pension from a source outside Hong Kong or compensation for loss of employment.
The territorial principle of only taxing income arising in or derived from a trade within Hong Kong results in reduced or nil tax being levied in a variety of situations. Thus:
Hong Kong has arrangement with a number of jurisdictions for double taxation relief of shipping or airline income. It has also comprehensive double tax agreements with a number of jurisdictions to relieve taxation on income, for instance dividends, interest and royalties. The Hong Kong Inland Revenue Department allows a deduction for foreign tax paid on a turnover basis in respect of income which is also subject to tax in Hong Kong. Therefore, businesses operating in Hong Kong do not generally have problems with double taxation of income.
