Key Takeaways
- Form 8992 is the main IRS form used to compute GILTI inclusions for U.S. shareholders of CFCs.
- GILTI can arise even when the CFC made no cash distributions.
- The computation relies on accurate CFC-level information.
- A weak Form 5471 file often creates a weak GILTI file.
Form 8992 is the GILTI computation form for U.S. shareholders
The IRS says U.S. shareholders of controlled foreign corporations use Form 8992 and Schedule A to figure their global intangible low-taxed income inclusions under section 951A. That makes Form 8992 the bridge between CFC information and a current-year GILTI inclusion. It is not simply an optional analysis worksheet.
No distribution is required for the inclusion problem to appear
GILTI is an inclusion regime, not a dividend regime. A founder may receive no cash from the CFC and still face a U.S. inclusion through the Form 8992 process. This is one of the most important mindset shifts for first-time CFC owners.
The form depends on CFC-level data flowing in correctly
The Form 8992 instructions say the U.S. shareholder uses information from each CFC, including data from Schedule I-1 of Form 5471. That means a weak 5471 file usually becomes a weak 8992 file. The GILTI computation is only as good as the corporation-level reporting feeding it.
