Abstract

Officially assessed land price has been the index of South Korea since 1989 throughout different sectors of tax and welfare. Officially assessed land price is used as a tax valuation for the tax on property holdings, and the equity of such is the most important factor in the fair taxation for the people of South Korea. On this wise, this research analyzed and verified the horizontal and vertical inequity of officially assessed land price in Seoul by using the real transaction data between 2016 and 2018. In fact, Seoul's assessment ratio for the entire three-year period was 60.64% and it showed to increase each year. Horizontal equity was found to be most favorable in 2017, and the horizontal equity of each borough of Seoul appeared to improve each year. Vertical inequity was found to have reverse inequality in most boroughs of Seoul, however, some parts of Gangnam districts such as Gangnam-gu, Seocho-gu, and Gangdong-gu presented progressive inequality. Such example showed the need for improvement in terms of balance by each borough. The use of quantile regression demonstrated reverse inequality in most quantile, but, the differences in the value of the coefficient by each quantile showed the need for improvement of officially assessed land price with the equity of each quantile. Through the equity verification of officially assessed land price, it was analyzed that the lack of equity was found by year, by borough, and by use district. In order to redeem the lack of equity, the government must systematically supplement the real-estate disclosure system by initiating ratio studies to verify horizontal and vertical equity.

우리나라의 공시지가 제도는 1989년 도입되어 각종 조세와 복지 등 여러 분야에 걸쳐 활용되어 왔다. 공시지가는 부동산의 보유세를 대표하는 재산세에 대한 과세평가액으로 활용되고 있으며, 국민 공평과세에 있어서 공시지가의 형평성은 가장 중요한 요소라고 할 수 있다. 이에 본 연구는 서울특별시의 토지의 실거래가격을 활용하여 2016~2018년 공시지가의 형평성을 분석하고 검증하였다. 그 결과 서울특별시의 현실화율은 해마다 점진적으로 상승하는 것으로 나타났으며, 3년 전체 현실화율은 60.64%로 나타났다. 수평적 형평성은 2017년이 가장 양호한 것으로 나타났으며, 해마다 자치구별 수평적 형평성이 개선되는 것으로 나타났다. 수직적 형평성은 대부분 지역에서 역진적 불형평성이 존재하는 것으로 나타났지만 강남구, 서초구, 강동구 등 강남권역에서 누진적 불형평성으로 나타나 자치구별 균형성 측면에서의 개선이 필요한 것으로 확인되었다. 분위 회귀분석 결과는 대부분 분위에서 역진적 불형평성이 나타났지만, 분위별 계수 값에 차이가 존재하여 공시지가 분위별 형평성 개선이 필요한 것으로 확인되었다. 공시지가 형평성 검증 결과 연도별, 자치구별, 용도지역별 형평성이 결여된 것으로 분석되었으며, 이를 보완하기 위해 정부는 비율 연구를 도입하여 수평적·수직적 형평성을 검증하고 부동산 공시 제도를 체계적으로 보완·점검해야 한다.
