Korea's wealth tax was divided into property tax and comprehensive real estate tax when the comprehensive real estate tax was introduced in 2005, and since then, it has developed into a complex system with various burden enhancement and relief systems for each tax category. This study examines the dual burden and restriction structure of Korea's wealth tax system and examines how to rationalize the wealth tax burden according to the taxpayer's ability to pay through the example of the United States.
 The holding tax system tries to moderate the tax burden by operating the tax burden ceiling, fair market value ratio, tax credit, and overstatement limit for property tax and comprehensive real estate tax, respectively.

It is also necessary to consider introducing a monthly payment system for property taxes for taxpayers' convenience.
