Spain’s wealth tax has seen a significant increase in recent years. The latest available data (2023 filings) shows that over 192,000 taxpayers declared wealth, with total declared assets approaching €1 trillion.
This reflects a major shift in how wealth tax is applied and enforced in Spain.
The increase in taxpayers is largely linked to the introduction of the Solidarity Tax on Large Fortunes (ISGF) in 2022.
This national tax applies to high-net-worth individuals and effectively:
Overrides regional reductions in some cases
Ensures taxation of large fortunes across Spain
In response, some regions adjusted their approach to wealth tax to retain tax revenue locally.
Total taxpayers: ~192,000
Total declared wealth: ~€930+ billion
Average wealth per taxpayer: ~€4 million
Total tax collected: close to €2 billion
Around 75% in financial assets (shares, funds, deposits)
Around 18–20% in real estate
Smaller portions in other assets (business interests, luxury assets, etc.)
Spain remains one of the few European countries with an active wealth tax system.
For taxpayers, this means:
Greater transparency
Increased reporting requirements
More consistent enforcement across regions
Non-residents are only taxed on Spanish-based assets, but this still includes:
Real estate
Spanish bank accounts
Investments located in Spain
If your assets exceed certain thresholds, you may need to file wealth tax.
