The situation: A foreigner working in China thinks his income from abroad is irrelevant to Chinese tax, but he stayed over 183 days a year for several consecutive years.
Applicable law: Someone without a domicile in China who stays 183 days or more in a tax year is a 'tax resident' subject to individual income tax. China-sourced income is taxable regardless. Foreign-sourced income depends on residence and its length (with a 'six-year' rule that may exempt foreign income under conditions of broken residence and filing). Salaries are withheld monthly with an annual reconciliation.
Outcome: The foreigner was classified a tax resident and settled up via annual filing; planning his days of stay in advance would have clarified his duties early.
