Spain Keeps Its Wealth Tax: Practical Effects Compared with France, Italy, Portugal, Belgium, Switzerland and Norway
Spain, together with Norway and Switzerland, is one of the few European countries that continues to tax the net wealth of individuals on a recurring basis. Unlike jurisdictions that have abolished or limited this form of taxation, Spain retains the Wealth Tax (Impuesto sobre el Patrimonio, IP) and, in addition, the Temporary Solidarity Tax on Large Fortunes (Impuesto Temporal de Solidaridad de las Grandes Fortunas, ISGF), the latter designed as a state-level surcharge to harmonise taxation. This framework directly affects the tax burden on high-net-worth individuals, wealth mobility and planning (residence, asset structure and borrowing).
How it works in Spain (current framework)
- IP: An annual tax on net wealth, governed by state legislation with regional latitude (exempt thresholds, rates and reliefs). The Spanish Tax Agency (AEAT) provides the procedures and manuals for each tax year. AEAT: Wealth Tax
- ISGF: A complementary state surcharge on the IP for wealth above €3 million. Its stated purposes are revenue raising and harmonisation in response to regional IP reliefs (for example, in regions with broad IP exemptions). The Constitutional Court upheld the basic design’s constitutionality in November 2023, and regional appeals have been dismissed over time. Debates and pending decisions remain, but the tax continues to apply in 2025. Official State Gazette ruling
Key implication: For high-net-worth individuals resident in Spain, the ISGF’s state-level “ceiling” neutralises strategies based solely on regional IP reliefs. Tax optimisation requires more sophisticated asset structures (family businesses, qualifying shareholdings, properly substantiated debt, the main home, and so on) and governance—not merely “regional tax arbitrage.”
At a glance: Spain compared with other countries
| Country / tax | General wealth tax? | Typical tax base | Indicative thresholds | Indicative rates* | Planning points |
|---|---|---|---|---|---|
| Spain (IP + ISGF) | Yes (IP) + state surcharge (ISGF) | Resident’s worldwide net wealth | IP: varies by autonomous community; ISGF: from about €3m | Progressive bands (IP varies by region; ISGF has its own scale) | Family business exemption; main home; optimise genuine debt; consistent valuations |
| France (IFI) | No (real estate tax only under IFI) | Real estate and related rights only | From about €1.3m of net real estate assets | Approx. 0.5%–1.5% | Diversify into non-real-estate assets; take care with real-estate structures (SCI, usufructs) |
| Italy (IVIE/IVAFE) | No (taxes on assets held abroad) | Real estate and financial assets abroad | No general minimum wealth threshold | IVIE: approx. 1.06% on foreign real estate; IVAFE: rates vary by instrument | Foreign real estate and portfolios matter; comply with RW foreign-asset reporting (monitoraggio) |
| Portugal (AIMI) | No (real-estate surcharge) | High-value urban real estate | Specific thresholds and deductions | Approx. 0.7%–1.5% | Relevant to prime real-estate portfolios; coordinate with IMI and consider whether assets are used in a business |
| Belgium (securities accounts) | No (limited tax) | Securities accounts (high threshold) | From about €1m (annual average) | Approx. 0.15% | Moderate burden on financial custody; monitor anti-fragmentation rules and future reforms |
| Norway (national + municipal) | Yes | Net wealth with valuation discounts | National and municipal bands | Approx. 0.85%–1.1% effective | Sensitive to valuations; the mix of business and non-business assets is critical |
| Switzerland (cantonal/communal) | Yes (not federal) | Net wealth, by canton | Cantonal thresholds | Approx. 0.1%–1% marginal | Choice of canton; wide variation in tax burden; legal certainty |
* These ranges are indicative and depend on annual rules, bands, valuations and location (autonomous community, canton or municipality). Any planning should be modelled on a case-by-case basis.
The continued existence of the Wealth Tax and the Solidarity Tax on Large Fortunes makes Spain one of the more demanding European countries for high-net-worth individuals. Unlike France, Italy or Portugal, which have opted for partial or specific levies—such as France’s IFI or Portugal’s AIMI—Spain retains a two-layer system that applies to net wealth as a whole, without distinguishing between financial and real-estate assets. This requires high-net-worth individuals to reconsider their asset structures with a strategic, long-term perspective.
The first step is to prepare a complete picture of the assets, identifying assets used in business activities, genuine liabilities and any applicable exemptions. Secondly, it is essential to diversify and professionalise wealth management, reducing exposure to illiquid assets and introducing financial or business instruments that can provide returns and tax flexibility.
The family business remains a preferred tax-planning tool where there is genuine substance, effective management and appropriate remuneration. It is also advisable to maintain up-to-date, documented valuations consistent with personal income tax and corporate tax returns, to avoid discrepancies in future audits.
From an international perspective, changing tax residence only makes sense when it reflects a genuine relocation of one’s life. European tax authorities are tightening residence tests, and cooperation between countries is becoming closer. Any move should therefore be supported by robust evidence and coherent succession planning.
Ultimately, high-net-worth individuals should replace an outdated focus on evasion or simple tax savings with comprehensive, transparent and efficient planning, combining tax, liquidity, asset protection and intergenerational transfers. Legal certainty, forward planning and professional governance are now essential pillars for protecting wealth amid increasing global tax scrutiny.
I had a really urgent problem in the middle of the summer that I needed to get fixed. I tried contacting a bunch of agencies but they were either unavailable, slow, had terrible service or were crazy expensive (one company quoted me 1000€!). Josep replied to me within 10 minutes and managed to submit my forms on the deadline and all for a great price. He saved my life - 100% recommend!
