Jin Air (LJ, Jeju) is challenging plans by South Korea's National Tax Service to tax pilots' take-off and landing allowances retrospectively, with the airline estimating the potential tax burden at KRW10 billion won (USD7.4 million). It has appointed law firm Kim & Chang and has requested a review before the tax is formally assessed. The authority intends to collect five years of income tax, treating the allowances as earnings, whereas Jin Air argues that they reimburse expenses incurred during pilots' stays away from base. The proposed taxation is on hold pending the review, which is expected in November 2026.
