The Lee family behind Samsung Electronics has finished paying 12 trillion won (roughly $8.7 billion USD, or about 40 billion Brazilian reals) in inheritance taxes, the largest such payment in South Korean history. Lee Jae-yong, the 57-year-old chairman and grandson of Samsung's founder, made the final installment in May 2026 alongside his mother Hong Ra-hee and sisters Lee Boo-jin and Lee Seo-hyun. The six-installment payment stretched across five years following the October 2020 death of his father, Lee Kun-hee, who left behind a 26 trillion won fortune including real estate, Samsung shares, and masterworks by Picasso and Salvador Dalí. South Korea's 50 percent inheritance tax rate ranks among the world's highest, and this particular bill equaled roughly 1.5 times the country's entire inheritance tax revenue for 2024. Investors watched the payment schedule obsessively because selling off Samsung shares to cover the tab could have shattered the family's control over the chaebol, the sprawling conglomerate encompassing everything from semiconductor fabrication to shipbuilding to life insurance. Samsung is South Korea's largest chaebol, and its Electronics division alone makes it one of the planet's dominant smartphone manufacturers and memory chip producers. The AI boom doubled the family's combined net worth past $45 billion in the past year as global demand for Samsung's computer chips exploded. But the tax drama was just the closing act of a far messier succession story. In 2017, Lee Jae-yong landed in prison for his role in a massive corruption scandal that also toppled President Park Geun-hye. Prosecutors accused him of funneling money to foundations run by Park's confidante Choi Soon-sil in exchange for government support of a 2015 merger between Samsung C&T and Cheil Industries. That merger, prosecutors argued, was rigged through accounting fraud and stock manipulation to consolidate Lee's grip on Samsung Electronics, the crown jewel of the empire. Lee denied the fraud charges but was convicted of bribery in 2017. Millions of South Koreans took to the streets of Seoul in 2016 demanding Park's impeachment, and both she and Lee ended up behind bars. The stakes were existential because Samsung's founding family has maintained control through three generations via a Byzantine web of cross-shareholdings among dozens of subsidiaries. When Lee's father suffered a heart attack in 2014, the younger Lee took de facto control, but the complicated ownership transfers needed to cement his position hadn't finished. Critics questioned whether Lee Jae-yong, seen as quieter and more cautious than his aggressive father, had the ruthlessness to run a company that accounts for roughly 20 percent of South Korea's GDP (Gross Domestic Product). His sister Lee Boo-jin, who runs the Hotel Shilla luxury hotel chain, was widely considered more capable. Lee Jae-yong's own pet project, e-Samsung, had flopped during the dot-com crash. The family had already endured one brutal succession fight in 1976 when Lee Kun-hee, the youngest son, was chosen over his older brothers to lead Samsung, sparking a forty-year feud that erupted into lawsuits in 2012. In July 2025, South Korea's Supreme Court finally acquitted Lee Jae-yong of the fraud charges related to the 2015 merger, ending a decade of criminal proceedings. But Lee emerged from the ordeal with a radical promise that broke with chaebol tradition entirely. Standing before the court, he pledged there would be no more succession controversies because he would not pass management rights to his own children. After 87 years of father-to-son control at Samsung, Lee Jae-yong is walking away from the dynasty model. The question now hanging over South Korea's most powerful company is simple and terrifying: who runs Samsung when Lee is done?
