Spain's ordinary Wealth Tax (Patrimonio) is an annual tax on net worldwide assets (residents) or Spanish-sited assets (non-residents) held as of December 31. The state default allowance is €700,000/person plus up to €300,000 for a primary residence (Catalonia/Valencia lower the base allowance to €500,000); rates run 0.2-3.5% depending on the autonomous community. The separate, indefinite Solidarity Tax on Large Fortunes (ITSGF) applies nationwide to individuals with net global assets over €3,000,000, acting as a floor even in regions (Madrid, Andalucía) offering 100% ordinary wealth tax rebates: 1.7% (€3M-5M), 2.1% (€5M-10M), 3.5% (over €10M), with regional wealth tax paid credited dollar-for-dollar against the Solidarity Tax liability, filed via Modelo 718.
