Spanish Wealth Tax 2026: What Every Costa Blanca Property Owner Must Know
6 June 2026 · Hansson & Hertzell
Spain's Impuesto sobre el Patrimonio applies to non-residents owning Spanish property above €700,000. Here's who pays, how it's calculated, and how the Valencian exemption works.
Spain's wealth tax (Impuesto sobre el Patrimonio, IP) is one of the most misunderstood taxes among international property buyers. Many buyers don't realise it exists until they receive a demand; others worry unnecessarily because they're well below the threshold. This guide cuts through the confusion and tells you exactly where you stand.
What Is the Spanish Wealth Tax?
The Spanish wealth tax is an annual tax on net assets — the total value of all your assets in Spain minus any Spanish liabilities (like a Spanish mortgage). It's paid annually and applies to both residents and non-residents, though with very different thresholds.
Non-residents pay wealth tax on their Spanish assets only — primarily Spanish property.
Residents pay wealth tax on their worldwide assets (subject to any double taxation treaties).
For most Costa Blanca buyers — non-residents owning property in the Valencian Community — the key question is simply: does the value of my Spanish property exceed the threshold?
Who Actually Pays It?
The honest answer: relatively few international buyers.
Here's why. The threshold for non-residents is €700,000 net of Spanish assets. This is the national minimum exemption. In practice, for a husband-and-wife purchase of a property jointly owned, each person's share is assessed separately — meaning a jointly owned property worth €1.2m gives each person a €600,000 exposure, below the €700,000 threshold.
Additionally, the Valencian Community — which covers all Costa Blanca properties — has historically applied a 100% bonus on wealth tax, meaning Valencia-region residents and property owners paid zero. However, this regional bonus has been subject to political uncertainty. Check the current year's rules with your gestor, as the bonus is applied at the autonomous community level and can change.
There is also a separate national "Solidarity Tax" (Impuesto Temporal de Solidaridad de las Grandes Fortunas), introduced in 2022, which applies to net assets above €3,000,000. This backstops the wealth tax in regions (like Madrid) that previously set it to zero. For most buyers, this is irrelevant.
How Is Wealth Tax Calculated?
The tax base for wealth tax is the highest of three values for your Spanish property:
- The official catastral value
- The ITP/AJD assessed value (from your purchase deed)
- The actual purchase price paid
For most buyers who purchased at market value, the purchase price is the relevant figure.
The tax base is reduced by any Spanish mortgage outstanding. So a property purchased for €500,000 with a €200,000 Spanish mortgage has a net taxable base of €300,000 — below the threshold.
The wealth tax rates are progressive:
- Up to €167,129: 0.2%
- €167,129–€334,253: 0.3%
- €334,253–€668,500: 0.5%
- €668,500–€1,337,000: 0.9%
- €1,337,000–€2,673,999: 1.3%
- €2,673,999–€5,347,998: 1.7%
- €5,347,998–€10,695,996: 2.1%
- Above €10,695,996: 2.5%
These are national rates — autonomous communities can modify them.
Worked example: Non-resident owns a €900,000 villa in Moraira outright (no mortgage). Net taxable base: €900,000. Subtract the €700,000 exemption: €200,000 taxable. Tax at 0.2–0.3% on this amount: approximately €540–€600 per year.
When and How Is It Filed?
Wealth tax is an annual self-assessment declaration (Modelo 714). The deadline runs from April to June, coinciding with income tax season. Non-residents file through the Agencia Tributaria online or through a gestor.
Non-residents with assets above the threshold who fail to file face penalties. The common mistake is not realising you have an obligation — particularly if your property has appreciated significantly since purchase.
Is Wealth Tax Relevant for Most Costa Blanca Buyers?
Practically speaking, the vast majority of H&H clients are not affected:
- Properties purchased for under €700,000 individually (or under €1.4m jointly) are below the threshold
- The Valencian Community bonus (when active) eliminates the liability entirely for residents
- Spanish mortgages reduce the taxable base significantly
For buyers of high-value properties (above €1m+ sole ownership, or €2m+ joint), wealth tax is a real consideration and should be factored into running costs.
Planning Considerations
Mortgage offset: Financing part of the purchase with a Spanish mortgage reduces the net taxable base. A €500,000 mortgage on a €1.5m villa brings the net taxable base down to €800,000 (vs the €700,000 threshold) — a significant reduction.
Joint ownership: Registering property in both partners' names splits the taxable base between two individuals, each with their own €700,000 exemption.
Company ownership: Some high-net-worth buyers consider Spanish or non-Spanish company structures. This is a complex area with significant tax and legal implications — specialist advice is essential.
Declarations even at zero: Some gestos recommend filing a zero-value wealth tax declaration even when you're below the threshold, to establish a paper trail with the tax authority. Discuss with your gestor.
Double Taxation Treaties
The UK and Sweden both have double taxation treaties with Spain. These treaties generally prevent you from being taxed on the same wealth in both countries. However, Spain's wealth tax is not always covered by these treaties — the specifics depend on the treaty and the asset class. UK residents in particular should take specialist cross-border tax advice.
