Income Taxes [Abstract] |
Income Taxes | 11. Income Taxes Income tax expense for the six months ended September 30, 2025 and 2024 differs from the U.S. federal statutory rate primarily due to the tax treatment of income attributable to noncontrolling interests in IBG LLC. These noncontrolling interests are held directly through a U.S. partnership. Accordingly, the income attributable to these noncontrolling interests is reported in the condensed consolidated statements of comprehensive income, but the related U.S. income tax expense attributable to these noncontrolling interests is not reported by the Company as it is generally the obligation of the noncontrolling interests. Income tax expense is also affected by the differing effective tax rates in foreign, state and local jurisdictions where certain of the Company’s subsidiaries are subject to corporate taxation. Deferred income taxes arise primarily due to the amortization of the deferred tax assets recognized in connection with the common stock offerings (see Note 4), differences in the valuation of financial assets and liabilities, and for other temporary differences arising from the deductibility of compensation and depreciation expenses in different periods for accounting and income tax return purposes. As of and for the six months ended September 30, 2025 and 2024, the Company had no material valuation allowances on deferred tax assets. The Company is subject to taxation in the U.S. and various states and foreign jurisdictions. As of September 30, 2025, the Company is no longer subject to U.S. Federal and State income tax examinations for tax years before 2016, and, except for India, is no longer subject to non-U.S. income tax examinations for tax years before 2011. On July 4, 2025, H.R. 1, commonly referred to as the “One Big Beautiful Bill Act” (“OBBBA”), was signed into law. The OBBBA makes permanent key elements of the Tax Cuts and Jobs Act of 2017, including 100% bonus depreciation and domestic research cost expensing. Additionally, OBBBA modifies the rules for Global Intangible Low Taxed Income (“GILTI”), renamed as Net CFC Tested Income (“NCTI”) under the OBBBA. ASC Topic 740 requires the effects of changes in tax rates and laws on deferred tax balances be recognized in the period in which the legislation is enacted. The Company is evaluating the impact of the OBBBA, and the results of such evaluations will be reflected on the Company’s Form 10-K for the year ending December 31, 2025. ‎
