What is the use of Schedule F in Form 990?

Schedule F is used by an organization that files IRS Form 990 to provide information on the activities conducted outside the United States by the organization at any time during the tax year.
 
These activities include grants and other assistance, program-related investments, fundraising activities, unrelated trade or business, program services, investments, or maintaining offices, employees, or agents who conduct such activities in regions outside the United States.

If your organization is required to report schedules other than A, B, and G, we recommend choosing our interview-based filing method.
