Cha Eunwoo Is Appealing His ₩13 Billion Tax Bill — Even Though He Already Paid It

Cha Eunwoo has paid a ₩13.0 billion KRW tax bill. He is also trying to get it cancelled.

Those two things sound like they contradict each other. They don't, and the reason why is the clearest way into this whole story.

What did Fantagio announce on August 2?

That Cha Eunwoo has filed a formal appeal with the Tax Tribunal, asking for the ₩13.0 billion assessment to be overturned.

The agency's statement was short: "Cha Eunwoo has filed an appeal in accordance with legally prescribed procedures in order to receive a proper tax determination. As this is a matter currently in progress, we are unable to share specific details."

Why appeal a bill he already paid?

Because in the Korean tax system these are separate steps, not alternatives.

Paying a disputed assessment stops interest and penalties from building up while the case is argued. It is not an admission that the assessment was correct. If the Tax Tribunal rules in his favour, the money is refunded.

So "I paid it" and "I think it's wrong" can both be true at once. That's what's happening here.

What was the National Tax Service actually investigating?

The National Tax Service did not accept that the company did anything.

What is a "one-person agency"?

This is the part worth slowing down on, because the same structure has come up in several recent Korean celebrity tax cases.

The setup works like this. A celebrity is already signed to a proper agency. Separately, that celebrity or a family member registers a company. The main agency then signs a service contract with the new company, and income gets routed through it.

Why does that matter? Tax rates. Top-bracket personal income tax in Korea reaches 45%. Corporate tax is more than 20 percentage points lower. Moving income from the personal side to the corporate side reduces the total bill.

That structure is not automatically illegal. It becomes a problem when the tax office decides the company is not really doing anything — that it exists only to lower the tax rate.

Why did investigators call it a paper company?

Three reasons came out of the audit, reported by Edaily on 22 January 2026.

• The registered address was in a remote part of Ganghwa Island, which investigators did not consider a plausible office for entertainment work
• Several imported cars were registered to the company and various expenses were run through it
• Investigators found no service the company provided that Fantagio was not already providing

On that basis, the National Tax Service concluded the company was not a real operating business, and that the financial benefit it generated ended up back with Cha Eunwoo. It determined he had underpaid income tax as a result.

What does Cha Eunwoo's side say?

That the company was legitimate and the reason for setting it up was practical.

His representatives have said that frequent changes in Fantagio's leadership left his mother wanting to protect her son's career, so she established a company to run management work directly. Their position is that it is "not a paper company, but a legally registered cultural and entertainment management agency."

Was Fantagio affected too?

Yes. Once the tax office refused to recognise the company as a real business, the paperwork between them became a problem.

In August 2025, the Seoul Regional Tax Office assessed Fantagio ₩8.20 billion KRW (about $5.60 million USD) in additional taxes, having concluded the agency processed false tax invoices issued by the mother's company. Value-added tax was included in that figure. Fantagio filed its own objection. It was rejected.

What did Cha Eunwoo say publicly?

He posted a second apology on Instagram — his first update to the platform since his initial statement, and one written while he is serving in the military.

The main points: he said he respects the National Tax Service's procedures and decisions, and that he has "paid all relevant taxes" to prevent further confusion.

He also took personal responsibility rather than directing it elsewhere. "Any part that I failed to fully check is entirely my responsibility. I will not try to avoid responsibility by saying I 'didn't know' or that it was 'someone else's decision' for any reason."

On the company itself, he said he set up a corporation during "a period of change and uncertainty" in his career, as preparation for continuing his activities more steadily, and that "there were areas I did not sufficiently oversee in that process." He stated the responsibility was his, not his family's or his company's.

He apologised to fans and to Aroha, and said he would review all aspects of his future activities to prevent a repeat.

How did the timeline unfold?

• Spring 2025 — Cha Eunwoo is audited by the Seoul Regional Tax Office's Investigation Division 4, the unit that handles major tax cases
• July 2025 — He enlists in the military. Tax authorities reportedly held the official audit notice until his enlistment was complete, at his request
• August 2025 — Fantagio is assessed ₩8.20 billion KRW
• 22 January 2026 — Edaily reports the case exclusively. He has been notified of over ₩20.0 billion KRW and his side has filed a pre-assessment objection
• Later — He apologises publicly and says he has paid all relevant taxes
• 2 August 2026 — Fantagio confirms an appeal to the Tax Tribunal over a ₩13.0 billion KRW assessment

What happens next?

The Tax Tribunal reviews the case and decides whether the assessment stands.

If it rules for Cha Eunwoo, the assessment is repealed and the money he has already paid comes back. If it rules against him, the payment stands — and he still has further routes available, including the Board of Audit and Inspection or the courts.

Fantagio has said it will not comment on specifics while the case is open, so there is unlikely to be much public movement until a decision comes down. Tribunal cases of this size are not quick.
