K-pop Star Cha Eun-woo Appeals 13 Billion Won Tax Bill Amid 'Paper Company' Dispute

The initial reassessment exceeded 20 billion won and was described as the largest celebrity tax bill in Korea, with Cha Eun-woo eventually paying about 13 billion won in back taxes.
The income routed through a one-person agency reportedly tied to Cha’s mother was labeled a 'paper company' by the National Tax Service, while Fantagio contends the firm is formally registered as a public arts and culture planning business.
Cha Eun-woo filed a Tax Tribunal appeal in accordance with legally prescribed procedures to obtain a legal determination, and his agency said the case is ongoing with no further details available.
Cha Eun-woo is currently serving in the military while the tax case continues to unfold.
The investigation into possible tax evasion included a July last-year intensive audit by the Seoul Regional Tax Office’s Investigation Division 4, which preceded the subsequent reassessment.
K-pop star and actor Cha Eun-woo has filed an appeal against a 13 billion won (about USD 9.5 million) tax bill — even after paying it in full. His agency Fantagio confirmed the appeal was submitted to South Korea's Tax Tribunal last month, calling it a move to get a formal legal ruling, according to Allkpop and Soompi.
The case stems from a National Tax Service reassessment that originally exceeded 20 billion won — described as the largest celebrity tax bill in Korean history. Cha paid the disputed amount earlier this year to avoid further confusion, but he is now challenging whether the assessment was fair, per Soompi.
The trouble began when the Seoul Regional Tax Office's Investigation Division 4 launched an intensive audit in July of last year. Investigators found that income had been routed through a one-person agency linked to Cha's mother. The National Tax Service labeled it a 'paper company' — a shell used to move money and pay lower corporate tax rates instead of higher personal income tax rates, according to Allkpop.
Fantagio pushed back on that label. The agency said the company is formally registered as a public arts and culture planning business — not a shell. The disagreement over the firm's status is at the heart of the dispute, per Soompi.
Cha Eun-woo is currently serving his mandatory military duty in South Korea. He filed the Tax Tribunal appeal from his base, according to Newsy Today and Yahoo News Malaysia. Fantagio said the filing followed all legally required steps and that the case is ongoing with no further details to share.
Cha had earlier stated he paid the full 13 billion won to stop further public confusion. He also said he respected the National Tax Service's process. But paying first does not mean giving up the right to challenge — Korean law allows taxpayers to appeal and claim a refund if the tribunal rules in their favor, per Head Topics.
If the Tax Tribunal sides with Cha, the government would refund some or all of the 13 billion won he already paid. If the tribunal rules against him, Cha can still take the case to civil court, according to Allkpop. Either way, the process could take months or longer to resolve.
The core legal question is simple: was the one-person agency a real business or just a tool to cut taxes? The answer will determine whether Cha's income should have been taxed at the lower corporate rate or the higher personal rate. The gap between those two rates is what drove the original bill past 20 billion won, per Soompi.
Cha Eun-woo's case is part of a broader push by South Korean tax authorities to crack down on celebrity tax strategies. Routing income through small personal companies to lower tax burdens is a common practice in the entertainment industry. The NTS has increasingly targeted these structures, according to Head Topics.
The original reassessment of more than 20 billion won made headlines as the single largest such bill handed to a Korean celebrity. Even after negotiations brought the final amount down to 13 billion won, the case drew wide attention across South Korea's entertainment world, per Newsy Today.
