Income generated from activities unrelated to the Schools exempt purposes is subject to tax under IRC Section 511. The School had no unrelated business income for the year ended July 31, 2025. Accordingly, no provision has been made for federal income tax. GAAP requires the evaluation of tax positions taken in the course of preparing the Schools tax return and recognition of a tax liability (or asset) if the School has taken an uncertain position that more likely than not would not be sustained upon examination by the Internal Revenue Service. Management has analyzed the tax positions taken by the School, and has concluded that as of July 31, 2025, there are no uncertain tax positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the combined financial statements.
