Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes AB Holding is a publicly-traded partnership (“PTP”) for federal tax purposes and, accordingly, is not subject to federal or state corporate income taxes. However, AB Holding is subject to the 4.0% New York City unincorporated business tax (“UBT”), net of credits for UBT paid by AB, and to a 3.5% federal tax on partnership gross income from the active conduct of a trade or business. AB Holding’s partnership gross income is derived from its interest in AB. AB Holding’s federal income tax is computed by multiplying AB qualifying revenues by AB Holding’s ownership interest in AB, multiplied by the 3.5% tax rate. AB qualifying revenues are primarily U.S. investment advisory fees. AB Holding Units in AB’s consolidated rabbi trust are not considered outstanding for purposes of calculating AB Holding’s ownership interest in AB.

In order to preserve AB Holding’s status as a PTP for federal income tax purposes, management ensures that AB Holding does not directly or indirectly (through AB) engage in a substantial new line of business. If AB Holding were to lose its status as a PTP, it would be subject to corporate income tax, which would reduce materially AB Holding’s net income and its quarterly distributions to AB Holding Unitholders.
