Dunamu Loses Lawsuit Seeking $19M in Corporate Tax Refunds After Venture Status Removal
Dunamu, the operator of South Korea’s largest cryptocurrency exchange Upbit, lost a 24.8-billion-won (approximately $18.7 million) corporate tax lawsuit, according to local news outlet The Korea Economic Daily. This legal action emerged after Dunamu was removed from the list of registered venture firms in December 2018. The Seoul Administrative Court ruled that since Dunamu was no longer a venture, it was not eligible for the associated tax benefits.

Losing venture status
In September 2017, Dunamu obtained certification as a venture company from the Ministry of SMEs and Startups. However, this certification was revoked in December of the following year. This revocation was due to an amendment to the Enforcement Decree of the Venture Businesses Act in October 2018, which resulted in the exclusion of “blockchain-based crypto asset trading and brokerage” from the venture business classification. Consequently, the withdrawal of this certification rendered the company ineligible for government tax incentives.
Tax refund request denied
In August 2020, Dunamu took action by formally requesting a refund of KRW 24.8 billion in taxes previously paid to the tax office. The foundation of its claim rested on its entitlement to venture company tax benefits up until the corporate tax period of 2018. However, its request was turned down, leading Dunamu to escalate the matter by initiating an administrative case against the tax authorities, following an unfavorable decision by the Korean Tax Tribunal.
Meanwhile, an amended version of the Act on Special Cases Concerning Taxation Restrictions, which excluded cryptocurrency-related industries from benefiting from tax reductions, went into effect in January 2019. Pointing to the effective date of this act, Dunamu argued that the company should be entitled to benefits applicable up until the corporate tax cycle of 2018. Furthermore, Dunamu highlighted its legal action, which had led the administrative court to suspend the effects of the venture company certification revocation from December 31, 2018, to January 18, 2019.
Court’s stance
Despite these arguments, the court rejected Dunamu’s argument and upheld that tax relief could not be granted for the tax year encompassing the date of the removal of its venture status. Additionally, the court affirmed that the tax authorities’ decision was valid since the venture status had been revoked in 2018, regardless of the amended Taxation Act’s implementation.
In disagreement with the court’s ruling, Dunamu has filed an appeal against the decision.
