The Tax Troubles of South Korea's Crypto King: The Story Behind Do Kwon's Trillion-Won Tax Bill
This article will discuss the former cryptocurrency tycoon, the once-glorious empire of Terraform Labs, and the massive tax penalties Do Kwon faces.
By: TaxDAO
Do Kwon was once hailed as South Korea's "Crypto King." But with the collapse of UST and the ensuing legal charges, his name has become synonymous with tax evasion and fraud. In May 2022, South Korea's National Tax Service (NTS) issued a tax bill of 1 trillion Korean won (approximately $78 million USD) to Do Kwon, co-founder and CEO of Terraform Labs. As early as June 2021, Terraform Labs had already drawn scrutiny from South Korean tax authorities over suspected tax evasion. Since his arrest in Montenegro, Do Kwon has been awaiting a final extradition decision. This article by FinTax explores the rise and fall of this former crypto tycoon and the once-mighty Terraform Labs empire, along with the massive tax penalties weighing on Do Kwon.

1. The Rise and Fall of Do Kwon
1.1 Do Kwon’s Rise and the Growth of Terraform Labs
Born in Seoul, South Korea in 1991, Do Kwon earned a bachelor's degree in computer science from Stanford University in 2015 and briefly worked as a software engineer at Microsoft and Apple. However, disillusioned by the lack of ambition he perceived in large corporations, he soon decided to strike out on his own. In January 2016, Kwon returned to South Korea to launch his first startup, Anyfi. While Anyfi itself is not central to our story today, the real crypto legend began when he teamed up with his university friend Nicholas Platias to explore blockchain technology, eventually founding Terraform Labs. Their vision was to create a new kind of monetary system—a decentralized stablecoin called TerraUSD (UST). The birth of UST marked the ascent of Do Kwon’s Terra empire, though at its foundation was a simple idea: to create the “most useful dollar possible.”
UST and LUNA were the core components of the Terra ecosystem. UST was an algorithmic stablecoin pegged to the US dollar. To mint UST, users had to burn an equivalent value of LUNA (a 1:1 swap); similarly, redeeming LUNA required burning an equal amount of UST. This created an arbitrage opportunity: traders could profit by burning or minting tokens whenever UST or LUNA deviated from $1, thus leveraging market supply and demand to maintain UST’s price stability. Crucially, UST was not backed by external assets but instead relied solely on market dynamics and incentive mechanisms—this key difference set UST apart from collateralized stablecoins like Tether, USDC, or DAI, which are backed by fiat or on-chain assets.
1.2 The Collapse of UST and Do Kwon’s Flight
In theory, the mechanism between LUNA and UST should have weathered various market fluctuations. But reality proved far more complex and unforgiving. In 2022, the Terra ecosystem collapsed because this mechanism failed to stabilize UST’s price amid market panic. When whales dumped UST and demand plummeted, UST began to de-peg. The system couldn’t adjust LUNA’s supply quickly enough, causing LUNA’s price to crash as well—so severely that it became impossible to buy back sufficient UST to maintain the dollar peg. Ultimately, both LUNA and UST spiraled into a dual collapse, triggering a broader downturn across the cryptocurrency market. LUNA plunged from a high of $119.51 to nearly zero, losing about $45 billion in market cap within a week. In South Korea alone, approximately 200,000 investors suffered massive losses, many losing their life savings. This unforeseen collapse didn’t just destroy the thriving UST—it shattered Do Kwon’s entire empire.
In the aftermath, Do Kwon fled and spent ten months on the run. In September 2022, South Korean prosecutors issued an arrest warrant, followed by a Red Notice from Interpol. On March 23, 2023, Montenegrin police detained Do Kwon at an airport for using forged documents. Upon learning of his capture, federal prosecutors in New York swiftly charged him with multiple counts including conspiracy to commit fraud, commodities fraud, securities fraud, wire fraud, and conspiracy to manipulate markets. The U.S. Department of Justice requested his extradition from Montenegro. Meanwhile, both South Korea and Singapore—jurisdictions with legal claims—also filed extradition requests. Although Montenegro’s courts have yet to issue a final ruling, the most likely outcome appears to be Do Kwon standing trial in South Korea.
2. Tax Evasion Charges and Legal Liability Facing Do Kwon
Beyond fraud allegations, Do Kwon and Terraform Labs face massive tax evasion charges. In June 2021, South Korea’s NTS launched a special tax investigation into Terraform Labs and its parent company, The Ancore Company, over suspected tax avoidance. During the probe, authorities discovered that Do Kwon held 92% of the shares in Terra Singapore, the Singapore-based legal entity of Terraform Labs. It was revealed that this Singaporean entity had secretly funneled substantial profits to shell companies in the British Virgin Islands (BVI), aiming to exploit BVI’s lenient tax regime. As the largest shareholder, Do Kwon stood to benefit the most from this tax-avoidance scheme. Such offshore tax strategies are not uncommon; for example, Samsung Electronics Vice Chairman Jay Y. Lee was questioned by South Korean prosecutors in 2021 over similar BVI profit-shifting activities. Offshore tax evasion remains a key enforcement target for the South Korean government.
The first step in determining tax evasion is establishing jurisdiction. Although Do Kwon structured his corporate holdings to shift most crypto-related profits to BVI entities—thereby minimizing actual tax liability—South Korea applies an “effective management” principle. Under this doctrine, even if a company is registered overseas, if its core operations are conducted from within South Korea, it must pay taxes there. Given that Do Kwon managed and operated his business primarily from South Korea, the country maintains strong grounds for asserting tax jurisdiction.
South Korea’s criteria for tax evasion closely align with international standards: First, there must be an act of evasion—such as underreporting or failing to report income, assets, or other taxable items. Second, the taxpayer must knowingly engage in such conduct with intent; negligence or misunderstanding does not constitute evasion. Third, the amount involved must meet certain thresholds. According to official case details, Do Kwon was fully aware of the corporate structure and tax arrangements. While South Korea does not specify exact monetary thresholds for tax evasion, the scale of the alleged evasion is undeniably significant. If the prosecution presents legally sound and sufficient evidence, a conviction for tax evasion is highly probable. This would mean lengthy imprisonment and a penalty of around 1 trillion Korean won. Should additional charges related to financial fraud also hold, Do Kwon risks not only financial ruin but spending the prime years of his life behind bars.
3. Reflections on Do Kwon’s Tax Case: From Crypto King to Prisoner
In the world of cryptocurrency, the Do Kwon saga exploded like a bombshell, prompting deep reflection across the industry—especially regarding regulatory oversight, and particularly tax compliance. A growing tension exists: on one hand, the crypto sector is vibrant and resilient, having grown geometrically through multiple boom-and-bust cycles, generating unprecedented levels of wealth. On the other hand, governments and regulators operate under relatively mature but traditional frameworks, seeking to bring the crypto space under control. While efforts to regulate crypto assets often aim to preserve financial order and economic stability, they risk stifling innovation and normal industry development. As Donald Trump criticized former SEC Chair Gary Gensler, the SEC’s strict regulatory stance may have weakened America’s global competitiveness in cryptocurrency and blockchain. Perhaps the best approach toward emerging technologies is cautious observation rather than heavy-handed intervention.
From a tax administration perspective, existing rules governing crypto assets remain unclear and inconsistent. Rapid innovation continually challenges the applicability of current regulations, effectively increasing the tax burden on the crypto industry. There is an urgent need for a transparent, stable, and industry-appropriate tax framework. Indeed, Do Kwon reportedly expressed dissatisfaction with South Korea’s tax system, believing it imposed excessive burdens. In comparison, shifting profits and wealth to zero-tax jurisdictions like BVI appeared economically rational. Yet, Do Kwon overestimated both his ability to evade taxes and the limitations of national tax authorities’ investigative capabilities. In truth, regardless of whether UST collapsed, Do Kwon would likely have faced tax investigations eventually—the collapse merely accelerated the timeline. In this sense, crypto assets are not just symbols of wealth and status for Do Kwon and countless other crypto millionaires—they can also become invisible chains. Once individuals choose to evade taxes or violate regulatory norms, those chains turn into real handcuffs.
Even though crypto tax regulations remain imperfect, until comprehensive reforms take place, stakeholders must prioritize compliance under current laws to avoid unnecessary penalties and losses. To ensure transactional compliance and mitigate tax risks, participants in the crypto space should consider the following:
First, strengthen internal tax governance. For crypto enterprises, establishing a comprehensive, systematic, and rigorous tax management framework is essential. From token issuance and distribution, to revenue accounting and cross-border capital flow monitoring, every stage must incorporate tax compliance considerations. Robust internal controls and audit mechanisms help ensure accuracy and completeness of tax reporting, effectively preventing potential liabilities.
Second, stay alert to policy developments and adapt strategies accordingly. The crypto industry remains in its early stages, with frequent changes in tax policies and significant regional variations. Investors and businesses must closely monitor policy trends from national governments and international organizations, staying informed about evolving regulations and supervisory directions.
Third, leverage professional expertise to enhance compliance. Given the high complexity and technical nature of crypto taxation, collaborating with legal, accounting, or tax advisory professionals experienced in digital assets is a prudent move. These experts can provide accurate guidance, develop customized compliance plans based on individual or corporate circumstances, identify potential risk areas in advance, and offer effective mitigation strategies. Additionally, specialized crypto tax reporting software can assist in processing vast volumes of complex transaction data efficiently and accurately, significantly improving filing precision while reducing human error-related risks.
