The government is moving to reform the tax system by increasing the ownership tax burden on ultra-expensive and non-residential homes and changing the long-term ownership special deduction for capital gains tax to focus on actual residence. We are currently looking into the appropriateness of the standards for ultra-high-priced homes whose publicly announced prices exceed KRW 1.2 billion and the system of applying tax credits based solely on ownership period and age. The capital gains tax special deduction system, which has been criticized for encouraging ‘smart one-home owners,’ will be reorganized to focus on actual residence. According to the relevant ministries on the 12th, the Ministry of Finance and Economy recently received an interim report on a research service on tax rationalization measures to normalize the housing market. It is known that comprehensive real estate tax and transfer tax will be mainly dealt with in the research service. The key is how to increase the burden of owning ultra-expensive homes. The government believes that the tax burden on owners of ultra-high-priced homes should be increased to curb real estate speculation. Currently, a household with one home must pay comprehensive real estate tax if the publicly announced price exceeds 1.2 billion won, and those with multiple homes must pay a comprehensive real estate tax if the total price exceeds 900 million won. As housing prices have recently risen, especially in Seoul and the metropolitan area, the number of subjects subject to comprehensive real estate tax has also increased.
