South Korea Fiscal & Treaty Framework
1. Bilateral Tax Accord & Jurisdictional Allocation (South Korea)
Relocating from South Korea to Spain activates the provisions of the Convention between the Republic of Korea and the Kingdom of Spain for the Avoidance of Double Taxation (1994). Under Article 15 of this bilateral accord, employment income is strictly allocated based on physical presence. If you move your tax residency from South Korea without electing the 24% Beckham Law regime via Form 149, the Spanish Tax Authority (AEAT) will subject your worldwide earnings to progressive Spanish income tax (IRPF) reaching up to 47% (and up to 54% in autonomous regions like Valencia).
By contrast, electing the Special Regime for Inbound Workers (Article 93 LIRPF) caps your Spanish employment tax at a flat 24% for active labor income up to €600,000 per year. Furthermore, foreign-sourced passive income (such as dividends, interest, or rental yield originating in South Korea) remains 100% EXEMPT from Spanish income tax.
2. Taxation of Korean Stock Option Plans (Venture Business Act tax deferrals), RSUs, and Severance Pay (Toejikgeum).
A critical area of divergence for executives from South Korea involves Korean Stock Option Plans (Venture Business Act tax deferrals), RSUs, and Severance Pay (Toejikgeum).. Under DGT Binding Ruling V0813-23, unvested equity grants are time-sliced across the vesting grant period: only the fraction of workdays physically performed on Spanish soil is added to your Spanish 24% taxable base.
Regarding corporate distributions, 10% Korean NTS dividend withholding rate under Treaty Article 10. This provides significant cash flow protection compared to standard non-resident rates.
3. Statutory Departure & Compliance Requirements
Prior to relocating from South Korea, you must address local departure formalities: National Tax Service (NTS) Overseas Relocation Tax Clearance & Article 118-9 Exit Tax. Submit Resident Tax final declaration to local ward office before departure. National Pension Scheme (Kukmin Yeongum) lump-sum refund evaluated under DTA Article 18.
