Growing Concerns Over Tax Blind Spots in South Korea’s Upcoming Virtual-Asset Taxation: The Rise of Crypto Cards and Potential for Tax Evasion

Concerns Mount Over Blind Spots in South Korea’s Virtual-Asset Taxation

As South Korea gears up for the full implementation of virtual-asset taxation next year, experts and investors are raising alarms about potential blind spots in the system, particularly concerning the use of crypto cards. These cards allow users to spend virtual assets earned overseas directly within South Korea, creating challenges for tax authorities aiming to track income generated from decentralized exchanges (DEXs) and personal wallets.

The Rise of Crypto Cards

Recent industry data reveals that the number of crypto card users in South Korea is approaching 40,000, with cumulative downloads of major crypto card applications reaching approximately 38,000 in the first half of this year. Crypto cards enable users to load assets like Bitcoin and Tether through dedicated apps, allowing them to make purchases at both online and offline merchants linked to global payment networks such as Visa and Mastercard. Payments can be made by converting crypto holdings into fiat currency at the time of purchase or by using pre-converted balances.

Taxation Framework and Challenges

Starting January 2027, income generated from the transfer or lending of virtual assets will be classified as miscellaneous income and taxed at a rate of 22% for profits exceeding the annual basic deduction of 2.5 million won ($1,800). However, the challenge lies in tracking income derived from overseas crypto markets, especially as South Korean investors transferred approximately 47 trillion won ($34 billion) in virtual assets to overseas exchanges and wallets in the first half of this year alone.

The Organization for Economic Cooperation and Development’s Crypto-Asset Reporting Framework (CARF) aims to bolster data collection and facilitate the exchange of crypto transaction data with 55 countries starting next year. Yet, DEXs, which operate without intermediaries, complicate the identification of user-level transaction data, making it difficult for tax authorities to capture every transaction.

The Blind Spot Dilemma

Experts warn that the ability to spend investment income earned overseas directly in South Korea could create a significant blind spot for tax enforcement. Crypto cards, often issued by overseas businesses, allow users to bypass domestic financial institutions, making it challenging for authorities to track transactions. Unlike traditional credit or debit cards, where spending patterns can signal unreported income, crypto card transactions may not provide sufficient data to identify South Korean users.

Cho Jae-woo, head of the Blockchain Research Institute at Hansung University, emphasized that user-level data for DEX transactions may not exist, complicating efforts to trace the flow of funds. “If assets accumulated through wallet addresses are used for living expenses via crypto cards, those transactions could easily escape the tax net,” he said.

Growing Demand Amid Tax Concerns

As the government prepares to enforce virtual-asset taxation, industry officials predict that demand for crypto cards may surge. Some investors express concerns about fairness, arguing that the current taxation framework disproportionately affects those using domestic exchanges. “If the government pushes ahead with crypto taxation without a broader consensus, more investors may turn to overseas exchanges and DEXs to avoid taxes,” warned one industry official.

Investor sentiment reflects this growing trend. One anonymous investor noted, “I support taxing income from virtual assets, but the same standards should apply to all investors.” Another investor shared that obtaining a crypto card was driven by fairness concerns rather than tax avoidance.

The Road Ahead

Experts caution that implementing taxation in an environment with significant blind spots could incentivize tax avoidance. “If taxation is introduced while areas remain easy to conceal, fair taxation may be difficult,” Cho stated. As the landscape evolves, the potential for a major boom in crypto card usage in South Korea looms large, raising questions about the effectiveness of the forthcoming tax regime.

As authorities work to tighten regulations and improve tracking mechanisms, the intersection of innovation and taxation in the crypto space remains a critical area of focus for both investors and regulators alike.
