South Korea tax agency audits 50 firms over corporate home misuse, ₩1.9 trillion at stake
Synopsis
South Korea's National Tax Service has launched audits of 50 firms after finding that 42 percent of surveyed corporate-owned luxury homes were being used privately by owners and their families. With ₩1.9 trillion in suspected irregularities and the probe now extending to overseas properties, this is one of Seoul's sharpest corporate tax crackdowns in recent memory.

An earlier review found 1,097 of 2,639 surveyed corporate homes — 42 percent — had been privately used by owners or family members.
Suspected tax irregularities across the 50 firms total ₩1.9 trillion .
One company spent over ₩30 billion in corporate funds to buy and renovate a luxury home in central Seoul for private use.
The NTS plans to expand the probe to corporate-owned homes abroad , including properties provided to owners' children studying overseas, as well as corporate payments for tuition and living expenses.
South Korea's National Tax Service (NTS) announced on Tuesday, 25 August that it has launched tax audits of 50 companies suspected of allowing owners and their family members to use corporate-owned luxury homes for personal purposes as part of alleged tax evasion schemes. The combined suspected tax irregularities across the firms amount to ₩1.9 trillion.
What Triggered the Audits
The crackdown follows an earlier NTS review of 2,639 corporate-owned homes across the country. That survey found that 1,097 properties — or 42 percent of those examined — had been privately used by company owners or their family members, raising red flags about systematic misuse of corporate assets to circumvent tax obligations.
The review focused on homes larger than 85 square metres with an officially assessed value exceeding ₩900 million (approximately $651,000), the threshold that makes them subject to South Korea's comprehensive real estate holding tax.
Key Allegations Against the Firms
According to the NTS, the suspect companies allegedly used corporate funds to provide private residences to owners' families, helped them sidestep multiple-home ownership and lending regulations, and maintained vacation properties for their exclusive personal use.
In one cited case, a company purchased a luxury home in central Seoul for more than ₩20 billion and spent an additional ₩10 billion in corporate funds on expansion and interior renovation — expenditures that would ordinarily be impermissible personal benefits.
A second company acquired a high-end property worth approximately ₩4 billion in a premium district of southern Seoul and allowed its owner to occupy it as a private residence without registering his residency there, according to the NTS.
A third company, based in the southeastern port city of Busan, purchased an apartment worth around ₩4 billion in Seoul for its owner's family and provided it rent-free.
Scope Set to Expand Overseas
The NTS said it plans to widen its investigation beyond domestic properties. Authorities intend to examine corporate-owned homes abroad that have reportedly been made available free of charge to owners' children studying overseas. The probe will also look into whether companies covered tuition fees and living expenses for these family members — potentially another layer of undisclosed personal benefits disguised as business costs.
Notably, this is part of a broader tightening of corporate tax compliance in South Korea, where regulators have signalled increased scrutiny of arrangements that blur the line between business assets and personal wealth.
What Comes Next
The audits are ongoing, and the NTS has not yet disclosed how many of the 50 companies may face formal penalties or prosecution referrals. The expansion of the probe to overseas assets suggests the investigation could grow significantly in scope. Analysts expect the findings to inform future regulatory guidance on how corporate real estate holdings are classified and taxed.
Point of View
Embedded in how South Korean conglomerates manage family wealth through corporate balance sheets. The extension of the probe to overseas properties and education expenses is a significant escalation: it signals that authorities are tracing the full lifecycle of alleged benefit, not just the asset purchase. What mainstream coverage may underplay is the regulatory arbitrage at work — corporate ownership of high-value real estate sidesteps both personal income tax and multiple-home ownership restrictions simultaneously. If the NTS findings hold up, the case for tighter beneficial-ownership disclosure rules in South Korea becomes hard to ignore.
