California Tax Appeals Office Rejects Automatic Unitary Treatment for Related Companies
A California Office of Tax Appeals decision addressed whether a holding company and an operating subsidiary were a unitary business for tax apportionment. The OTA found the Franchise Tax Board did not show sufficient dependency, contribution, or integration between the entities. The ruling confirms that common ownership alone does not make related companies unitary.
In Appeals of Watts, a nonprecedential California Office of Tax Appeals ruling issued Feb. 28, 2025, the dispute concerned a holding company and an operating subsidiary. The subsidiary was sold in stages, with the remaining stake—under half—transferred in 2012. The taxpayer treated the resulting gain as nonunitary on that year’s California return, while the Franchise Tax Board concluded on audit that the entities were unitary.
The OTA applied California’s dependency-or-contribution and three-unities tests. It found no meaningful intercompany financing, shared tax benefits, creditworthiness benefit, or significant day-to-day administrative integration; partial officer overlap was not enough. Prior unitary filings also failed to control because each tax year is assessed separately.
The ruling may affect California taxpayers with holding-company structures and their advisers by reinforcing that unitary status requires year-specific factual support, not merely common ownership. It could lead to more detailed documentation of intercompany dealings and may influence audit disputes over apportionment. Tax authorities and courts may also face clearer expectations about proving integration. The broader public impact is indirect, through how state corporate tax revenue and compliance costs are allocated among businesses.
