Mexico Fiscal & Treaty Framework
1. Bilateral Tax Accord & Jurisdictional Allocation (Mexico)
Relocating from Mexico to Spain activates the provisions of the Convenio entre los Estados Unidos Mexicanos y el Reino de España para Evitar la Doble Imposición (1992). Under Article 15 of this bilateral accord, employment income is strictly allocated based on physical presence. If you move your tax residency from Mexico 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 Mexico) remains 100% EXEMPT from Spanish income tax.
2. Taxation of Mexican Stock Option Plans, RSUs, and Employee Profit Sharing (PTU - Participación en las Utilidades).
A critical area of divergence for executives from Mexico involves Mexican Stock Option Plans, RSUs, and Employee Profit Sharing (PTU - Participación en las Utilidades).. 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, 5% capped withholding tax on corporate dividends 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 Mexico, you must address local departure formalities: SAT Formulario 39 (Aviso de cambio de residencia fiscal) submitted to Servicio de Administración Tributaria. Tax Residency Certificate from AEAT required to prove non-residency in Mexico under Article 9 CFF. AFORE (Administradora de Fondos para el Retiro) lump sum withdrawals evaluated under Article 18.
