Net CFC Tested Income

In more detail

Under the One Big Beautiful Bill Act, the GILTI regime is being relabelled as Net CFC Tested Income (NCTI) and revised for tax years beginning after 31 December 2025. The core idea — current US taxation of a controlled foreign corporation tested income — survives, but some of the calculation changes. Americans with UK companies should plan on current-year inclusion continuing under the new name.
