The Court of Tax Appeals ruled that the Revised Makati Revenue Code's taxation of holding companies was ultra vires and invalid. Specifically, the Code taxed holding companies at the same rates as banks and other financial institutions, which exceeded Makati City's authority under the Local Government Code. The Court also noted that dividends received by domestic corporations are not taxable under the National Internal Revenue Code. As a result, the tax assessment issued by Makati City against Michigan Holdings was cancelled. The ruling establishes that local tax ordinances must conform to limitations set by national law.
