South Korea Weighs BOK Crypto Reporting Plan and Conditional Exchange Tax
South Korea’s central bank has proposed monthly reports on some crypto users’ domestic holdings. A separate tax proposal could leave exchanges liable for a levy on revenue rather than profit. The reporting scope, legal basis and tax treatment remain uncertain in the available reports.
- BOK proposal: Monthly reports could cover users with a record of overseas transfers.
- Potential reach: A lawmaker’s office counted 1, 272, 878 users with relevant transfer histories.
- Possible tax: Exchanges could face a 0.5% to 1.0% levy on gross operating revenue if future rules bring them into the tax’s scope.
What the BOK’s reporting proposal would cover
The Bank of Korea (BOK) sent the Digital Asset eXchange Alliance (DAXA), which represents major South Korean exchanges, a draft reporting manual earlier in October, according to Seoul Economic Daily. The proposal calls for monthly reports on domestic crypto holdings.
Under the initial proposal, exchanges would report monthly on the domestic digital-asset holdings of users with at least one overseas-transfer record since July 19, 2024. The proposal also calls for personal information, but the reported material does not specify the data fields, retention period or access controls.
Chosun reported that the draft included dormant accounts, staked assets and tokens exchanges no longer support for trading. The available details do not say whether self-custodied assets would be included.
The BOK was also reportedly considering a narrower approach, covering transactions made after December 3 instead of using the July 2024 lookback. This was a possible revision, not a confirmed final rule, after exchanges raised concerns about the reporting plan. The reports do not say whether the proposal was later finalized.
Two reporting systems, with different jobs
Mandatory reporting of cross-border digital-asset transfers is scheduled to begin on December 3 under the revised Foreign Exchange Transactions Act. The reports give no year for that date, so it should not be inferred from the surrounding chronology.
The transfer-reporting requirement and the BOK’s proposed monthly balance reports are separate measures. One covers cross-border transfers. The other would provide recurring information about domestic holdings for users identified through records of overseas transfers. The available reports do not explain whether data from one system would feed into the other.
The legal basis and enforcement process for the BOK’s proposed manual are also unclear. Reports describe a draft under discussion, but do not establish whether the manual itself would be binding, which agency would enforce it or how its requirements would fit with existing law.
Rep. Park Soo-young’s office reportedly estimated that 1, 272, 878 users at South Korea’s five largest won-based exchanges had relevant transfer records between July 19, 2024, and September 30, 2026. That is an estimate of users with a transfer history, not a confirmed count of people covered by final rules. A reporting scope that looks forward could produce a different total.
The BOK met with domestic exchange officials on October 16 to discuss implementation. Exchange representatives reportedly said monthly balance reporting would be difficult under the current legal framework. They also said exchanges could not arbitrarily block deposits or withdrawals from customers who refused consent to information-sharing. These are industry concerns. The reports do not establish that the law definitively prevents exchanges from taking any particular action.
A BOK official told Seoul Economic Daily that the bank was consulting with the Ministry of Economy and Finance and might narrow the reporting scope. The official said the details would be finalized during November, as the December 3 start date approached. The reports do not confirm whether that timetable was met.
Oversight versus privacy and practicality
Cross-border crypto transfers can be hard for authorities to monitor. Reporting may help them identify suspicious flows. But collecting recurring balance information and personal details from a potentially large group of users raises questions about privacy, proportionality and implementation.
Park’s office reportedly criticized the scale of the proposed data collection. Exchange representatives warned that burdensome rules could push activity toward overseas platforms. These remain concerns, not proven outcomes. The available reporting offers no evidence that the proposal has driven users away from domestic exchanges or made investigations less effective.
The practical questions are simple but consequential: what information must exchanges submit, how will it be protected, and what happens when a customer refuses consent? The available reports do not answer them.
Why a proposed law could change exchange taxes
South Korea’s Virtual Asset User Protection Act has been in force since July 2024. It requires exchanges to hold customer cash with banks, segregate customer assets, maintain insurance or reserves against hacking losses, and monitor abnormal trading. The law also criminalizes insider trading and market manipulation.
The law does not establish the full licensing and market framework proposed for the next phase of regulation. Exchanges currently operate under an anti-money-laundering registration system. The proposed Digital Asset Basic Act would introduce formal licensing for digital-asset businesses, issuer-disclosure rules and a legal route for won-pegged stablecoins.
How the Act classifies exchanges could also affect their tax status. Digital-asset companies are currently categorized as information and communications businesses. The education tax applies to certain financial and insurance businesses, so exchanges could face it if the new framework classifies them as financial businesses.
Seoul Economic Daily reported that covered businesses pay the education tax at a rate of 0.5% to 1.0% of gross operating revenue. That means revenue before operating costs are deducted, not profit. The report cited a projected combined annual tax burden of more than 13.4 billion won, around $10 million, for Dunamu and Bithumb if the levy applies.
The available reporting does not provide the underlying calculation or revenue figures. It also does not establish whether a financial-business classification alone would trigger the tax or whether tax law would need to change separately. The estimate is conditional, not a bill exchanges have been told to pay.
The Basic Act remains the key uncertainty
The proposed Digital Asset Basic Act has been delayed amid reported disagreements involving the Financial Services Commission (FSC), the BOK and the ruling Democratic Party. Seoul Economic Daily reported disputes over who should be allowed to issue won-pegged stablecoins and a proposed 15% to 20% cap on major shareholders’ stakes in exchanges. These are reported proposals, not confirmed provisions of an enacted law.
On October 22, FSC Chair Lee Eog-weon said discussions were in their final stage and publication was expected “within this year.” The reported update gave no confirmed submission date. The available reports do not establish what happened after that statement.
Key questions and answers
-
What would the BOK’s draft require?
Monthly reports on domestic holdings and personal information for users with overseas-transfer records. The available reports do not establish the final scope, data fields or legal mechanics.
-
How many users could be in scope?
Rep. Park Soo-young’s office estimated that 1, 272, 878 users had relevant transfer histories through September 30, 2026. That is not a confirmed count under any final rule.
-
When does cross-border transfer reporting start?
The reported date is December 3 under the revised Foreign Exchange Transactions Act, but the year is not specified.
-
Is the education tax certain?
No. The reported 0.5% to 1.0% levy on gross operating revenue could apply if exchanges enter the tax’s scope. The required legal steps and final treatment remain unclear.
-
What would the Digital Asset Basic Act add?
The proposal would establish formal licensing, issuer disclosures and a legal route for won-pegged stablecoins. The reported updates do not confirm its final text or status.
South Korea’s next decisions will determine whether the reporting plan becomes a workable oversight tool or a broad demand for user data. They will also determine whether exchanges move into a tax category that could charge them on revenue even when costs leave little profit.
