Spanish wealth tax is a state tax with regional bonifications. The effective burden can range from near-zero (in historically bonified regions) to the full state scale (in non-bonified regions). The large-fortunes levy (ITSGF) overlays in regions that bonify.
Last updated: April 2026. Any figure is pending BOE / AEAT verification before publication.
Wealth tax by region (2026 snapshot)
| Region | Wealth Tax Position | ITSGF Impact | Effective Outcome |
|---|---|---|---|
| Madrid | 100% bonification | ITSGF applies in practice | Low–Medium |
| Andalucía | 100% bonification | ITSGF applies in practice | Low–Medium |
| Catalonia | No bonification | Not needed (full taxation) | High |
| Valencia | No bonification | Not needed (full taxation) | High |
What this means in practice
- “Bonified” regions (Madrid / Andalucía) no longer mean zero tax due to ITSGF
- Non-bonified regions (Catalonia / Valencia) apply full wealth tax scales
- The real outcome depends on your net assets, structure and residency

Frequently asked questions
Which autonomous community has the lowest wealth tax in 2026?
The lowest effective burden is usually found in regions applying substantial wealth-tax bonifications. However, this can change annually and may be affected by the ITSGF. We confirm the current position at assessment stage before giving tax-planning advice.
Does wealth tax apply if I am a non-resident?
Yes. Non-residents may be taxed on Spanish-located assets, with the general exempt allowance of €700,000 applying under obligation real. EU/EEA residents may, in certain cases, opt for the regional rules of the autonomous community where the greatest value of their Spanish assets is located.
Is the ITSGF separate from regular wealth tax?
Yes. The ITSGF is a separate state-level tax that operates alongside wealth tax and is designed to ensure taxation of large fortunes, particularly where regional wealth tax has been substantially bonified.
Can I structure around wealth tax via a holding company?
Sometimes, but this requires careful legal and tax analysis. Spanish anti-avoidance rules, beneficial-ownership tests, CFC rules, substance requirements and income-imputation rules can all affect the result. Structures that worked before the introduction of the ITSGF may no longer produce the same outcome.
What does Costaluz charge for a wealth-tax exposure assessment?
We offer a personalised quote initial wealth-tax exposure assessment based on your residency position, asset location, ownership structure and applicable autonomous community. After reviewing your profile, we confirm whether a full tax-planning report is advisable and quote that work separately.
