Spain’s wealth tax has seen a strong increase in compliance, particularly among high-net-worth individuals. Recent data shows that a large majority of individuals with very high net worth are now declaring and paying wealth tax—driven mainly by structural changes introduced in recent years.
This marks a clear shift toward greater enforcement and reduced tax planning gaps.
The key turning point was the introduction of the Solidarity Tax on Large Fortunes (ISGF) in 2022.
This national tax:
Applies to net wealth above €3 million
Operates alongside regional wealth tax systems
Ensures taxation even in regions with significant reductions (such as Madrid)
The result is a more consistent system across Spain, with fewer opportunities to avoid taxation through regional differences.
Strong increase in compliance among high-net-worth individuals
Total wealth declared approaching €1 trillion
Wealth tax revenue close to €2 billion
Significant increase compared to previous years
This reflects both policy changes and improved access to financial data.

Better cross-checking between tax authorities
This means:
High-value assets are easier to detect
Non-compliance is more likely to be identified
Consistency across filings is critical
