Foreign Branch category income is another income basket added by the TCJA for purposes of the Foreign Tax Credit (Form 1116).
What it includes
This category covers:
- Business income earned through a foreign branch,
- From one or multiple countries,
- That is part of a Qualified Business Unit (QBU) operating outside the U.S.
Simple explanation
A “foreign branch” is simply a business activity operating in another country without forming a separate foreign corporation.
Examples:
- A U.S. sole proprietor running a location overseas
- A partnership with a foreign office treated as a QBU
- A corporation with a registered branch office abroad
This category exists because foreign branch income often faces different tax regimes, so FTC rules keep it separate from passive, general, or GILTI income.
