부동산 양도소득세에 대한 연구 -장기보유특별공제를 중심으로-

Whenever the real estate policy was changed, the capital gains tax in Korea had been revised. And it made the tax regulations more complicated and difficult. In particular, various provisions on tax deduction and exemption can be pointed out as the main reason for increasing the complexity of the system. the scheme of special deduction for long-term holing is complicated to contain many kinds of policies against real-estate speculation in addition to the inflation adjustment to the increase in tax base. The purpose of this study is to examine the current problems and to present some improvements based on the special long-term deduction system of capital gains tax. We raise three issues. First, the current system includes too many provisions to achieve both economic and policy goals simultaneously, resulting in institutional irrationalities. Second, our simulation results using quantitative data suggest that the rational basis for deduction rate by holding period is insufficient and the adjustment for actual inflation is insufficient. Third, We point out that the application of tax exemption to a house for a family is applied irrespective of the size of capital gains, so it is difficult to expect the policy effect of detering speculators. This study gives some suggestions as follow: First, it is possible to increase the clarity and stability of the system by dividing the current capital gains tax system into long-term holding adjustment clauses for inflation indexing and special clauses that reflect policy objectives according to market conditions. Second, the deduction rate for each holding period can be replaced with the indexing for inflation(with GDP Deflator). Third, It could be effective in suppressing real estate speculation by reflecting residence period in the tax deduction condition of a house for a family.
