Reconstruction associations and residents are challenging South Korea’s reinstated excess-profit recapture system as Seoul projects levies totaling 2.169 trillion won across 46 complexes. Seocho District plans to impose charges sequentially on five complexes, beginning with Banpo Hyundai, now Banpo Centreville Asterium, whose levy is expected to be completed this year before the district’s authority expires at the end of 2026. The complex was completed in July 2021. Other projects in the sequence are Shinsung Villa, now Bangbae Centreville in the Forest; Shinbanpo 18, now Hautere Shinbanpo; Shinbanpo 21, now Hautere Banpo; and Banpo Jugong 1 Complex District 3, now Raemian Trinity One. Associations say they may seek injunctions and file administrative lawsuits over charges calculated on unrealized gains and based on housing-price estimates that do not reflect actual transaction prices. Raemian Trinity One faces a projected 514.94 billion won levy, or about 320 million won per member, while Hangang Mansion faces 472.26 billion won, or about 680 million won per member. The average projected burden across the 46 complexes is 121.74 million won per member. Uncertainty over final assessments is affecting resale prices, with buyers and sellers negotiating who will bear the future levy. Disputes have also emerged in Songpa District, where the assessed end-point value for Hillstate e-Pyeonhansesang Munjeong remained at 1.0444 trillion won after the association objected to the figure. Critics warn the system could delay reconstruction and reduce housing supply through postponed projects or smaller general-sale programs, including one-for-one rebuilding. Three National Assembly bills seek to abolish or reduce the levy, while officials and experts are debating changes to its calculation, scope and maximum rate of 50%.
