CFC rules vary from country to country, however, it is common in most CFC rules that:
Shareholders of foreign companies may have to tax the entire foreign company as domestic and hence all CFC income becomes local income
The reportable income generally includes income received by the controlled foreign corporation (CFC), like income from passive sources, including interest, dividends and royalties from unrelated parties; from purchasing and selling goods to related parties; or from non-operating, insubstantial, or passive businesses.
CFC rules may have a certain threshold for shareholding.
