A Study on The Effectiveness of Tax Assistance System

조세지원체계의 유효성에 관한 연구

Tax assistance system in Korea is a one that is designed by the central government to achieve specific policy objectives through the tax relief for economic activities or specific industries, leading to the development of the industries, Thus, the purpose of this study is to see if the government's direct tax assistance system for small and medium manufacturing firms is effective and then to contribute to establishing necessary policies for an effective tax assistance system based on the identification of a direct assistance system that is substantially useful to those firms. T- test was performed to see if there was a difference in tax burden between small and medium manufacturing firms and small and medium non-manufacturing firms and also to see whether the direct assistance system was effective. The results obtained from the statistical analyses are as follows: (1) The tax reduction rule applied to small and medium firms was turned out to be effective based on the fact that the effective tax rates of the small and medium firms to which the rule was applied were, on the average, significantly lower than those of the Listing large corporation which did not receive the tax benefit and also on the fact that the tax savings rates of the small and medium firms which could apply the rule were, on the average, significantly higher than those of the Listing large corporation to which the rule was not applied. (2) The tax credit rule applied to small and medium manufacturing firms was also turned out effective based on the same fact as described in the case of the application of the tax reduction rule.

본 연구는 우리나라 법인세제 하에서 기업규모와 기업특성 및 조세지원제도에 따라 발생하는 조세부담의 차이에 대한 실증적인 점증을 하고자, 상장 대기업과 중소기업을 대상으로 유효법인세율로 측정되는 조세부담의 차이가 기업의 규모 및 업종별로 어떤 차이가 있는지를 분석하였다. 선행연구를 검토하면서 우리나라 조세지원제도를 설명하였으며, 조세지원제도의 효과와 기업특성에 대한 가설을 설정한 다음 T-검정을 실시하였다. 연구결과를 요약하면 첫째, 조세지원에 따른 세액공제가 법인의 조세부담율에 실질적 영향을 미쳤으며 이는 조세지원제도의 유효성을 입증한 결과이며, 둘째, 중소기업에 대한 조세지원제도가 어느 정도 유효하다고 판단되었으며, 셋째, 제조업에 대한 조세지원제도도 어느 정도 유효한 것으로 나타나 종합적으로 조세지원제도는 그 목적을 어느 정도 달성하고 있는 것으로 나타난다. 하지만 법인세부담율에 영향을 주는 기타 요인(수출, 투자, 증자 등)을 반영하지 못하였고, 익금산입이나 손금산입등의 세무조정 내용을 반영하지 못한 점, 또한 단일연도의 자료만을 이용한 점등을 그 한계로 지적할 수 있다.
