Schedule G-1 (Form 5471): Cost Sharing Arrangement

Schedule G-1 (Form 5471), Cost Sharing Arrangement, is a separate schedule filed with Form 5471. The form says to complete a separate Schedule G-1 for each cost sharing arrangement (CSA) in which the foreign corporation was a participant during the tax year, and to report all amounts in U.S. dollars.

The schedule asks for a short description of the CSA, whether the foreign corporation joined it during the year, whether the CSA was in effect before January 5, 2009, the corporation's share of reasonably anticipated benefits, platform contributions made by a U.S. taxpayer, stock-based compensation and intangible development costs.

The About Form 5471 page says certain U.S. citizens and residents who are officers, directors or shareholders in certain foreign corporations file Form 5471 and its schedules.
