§951A Net Cfc Tested Income Included in Gross Income of United States Shareholders

Summary

If you are a U.S. owner of a controlled foreign company, you must add your "net CFC tested income" to your taxable income for the year. Net CFC tested income is your share of the company’s tested income minus your share of the company’s tested loss. Tested income means the company’s gross income after leaving out certain specific kinds of income (for example, income already taxed under subpart F, some foreign‑base company and insurance exceptions, related‑party dividends, and foreign oil and gas income) and then subtracting the deductions that go with that income. A tested loss is when those deductions are larger than that income. Your share is figured the same way the tax rules already figure shares for subpart F income. You count as a U.S. shareholder only if you owned stock in the company on any day of the year. A foreign company counts as a controlled foreign corporation if it was controlled at any time during the year. For many tax rules, this net amount is treated the same as subpart F income. The tax agency will make rules for applying it to other parts of the tax code when a company‑level calculation is needed. If you have net CFC tested income from several companies, a company with no tested income gets no part of the net amount; a company with tested income gets a share based on the ratio of your share of that company’s tested income to the total tested income used in the calculation.
