Spanish wealth tax applies to individuals who own taxable assets in Spain, including many non-resident property owners. For non-residents, the tax is generally assessed only on Spanish assets, such as Spanish property, Spanish bank balances and certain assets or rights located in Spain.

For international buyers, Spanish wealth tax matters before completion, not after. The way a property is valued, financed and owned can affect the taxable base, available deductions and filing position. This guide explains how Spanish wealth tax works in 2026, using the current 2025 tax year rules filed in 2026, and what non-resident property buyers should review before purchasing in Spain.

• Spanish wealth tax applies to net assets: the tax is calculated on the value of taxable assets after certain allowable debts and deductions.
• Non-residents are generally taxed only on Spanish assets: a non-resident does not usually declare worldwide wealth for Spanish wealth tax.
• Rates are progressive and filing is annual: the state scale runs from 0.2% to 3.5%, and the 2025 tax year is filed using Modelo 714 between 8 April and 30 June 2026.
• The general non-resident allowance is €700,000 per person: married couples and joint owners may each have their own allowance, depending on ownership and circumstances.
• Regional rules can affect the final liability: non-residents may be able to apply the rules of the autonomous community where the highest value of their Spanish assets is located.
• High-value estates may also fall within the solidarity tax: the Temporary Solidarity Tax on Large Fortunes applies to net wealth above €3 million and is filed separately.
• Equity release may reduce the taxable value of Spanish property: for higher-value properties, properly structured borrowing may be relevant to the net wealth tax calculation, but only with commercial substance, careful structuring and specialist tax and legal advice.

Spanish wealth tax, known as Impuesto sobre el Patrimonio, is an annual tax on the net wealth of individuals. Net wealth means the value of taxable assets and rights after deducting qualifying liabilities, charges and debts.

For Spanish residents, wealth tax can apply to worldwide assets. For non-residents, it generally applies only to assets located in Spain, rights that can be exercised in Spain, or obligations that must be fulfilled in Spain. For a non-resident property buyer, the main asset is usually Spanish real estate.

Spanish wealth tax is assessed on 31 December each year. The relevant question is what taxable assets and deductible liabilities you hold on that date. The Spanish Tax Agency confirms that non-residents subject to real obligation are taxed on Spanish assets, with deductions generally limited to charges, encumbrances and debts connected with those Spanish assets.

Spanish wealth tax can apply to residents and non-residents, but the scope is different for each group.

Non-residents are taxed by real obligation, which means Spanish wealth tax applies only to Spanish assets. For most overseas property owners, this includes Spanish real estate, Spanish bank accounts, certain investments held in Spain and other Spanish-situs assets.

A non-resident is generally required to file if either the tax calculation produces a payment due, or the gross value of their assets and rights exceeds €2 million before deducting debts.

Spanish tax residents are taxed by personal obligation, which means they may need to declare worldwide assets. Spanish residents may also be able to apply certain additional reliefs, including the main home exemption where the property qualifies as the taxpayer’s habitual residence.

For internationally mobile buyers, residence status should be reviewed carefully. Moving to Spain, spending more time in Spain, or changing where your centre of economic interests is located may affect your tax position.

The general Spanish wealth tax allowance for non-residents is €700,000 per person. This means a non-resident is typically only taxed on the taxable base above the allowance, after allowable deductions have been applied. The Spanish Tax Agency confirms that the €700,000 minimum exemption applies to non-residents subject to real obligation.

For example, if a non-resident owns a Spanish property and has a qualifying mortgage secured against that property, the outstanding debt may reduce the net Spanish asset value before the personal allowance is applied. The final calculation depends on valuation rules, ownership percentages, deductible debt, regional rules and any relevant reliefs.

The Spanish state wealth tax scale for the 2025 tax year filed in 2026 runs from 0.2% to 3.5%. The state scale applies where no different regional scale is available or selected. The Spanish Tax Agency’s 2025 Wealth Tax Manual sets out the state scale applicable for the 2025 tax year. View the state wealth tax scale.

For non-residents, Spanish wealth tax generally applies to assets located in Spain or rights that can be exercised in Spain. The most common taxable asset for overseas buyers is Spanish property.

• Spanish real estate, including apartments, villas, plots and land
• Spanish bank deposits and cash balances
• Certain shares, investments or financial rights connected with Spain
• Vehicles, boats, jewellery, art or high-value personal assets located in Spain
• Business or professional assets located in Spain, unless a specific exemption applies
• Certain insurance policies or annuity rights connected with Spain

For real estate, the taxable value is not always simply the purchase price. Spanish property valuation rules can consider cadastral value, acquisition value and other tax reference values. A Spanish tax adviser should confirm the correct figure for filing.

Spanish wealth tax is charged on net wealth, so qualifying debts can reduce the taxable base. For non-residents, deductible liabilities are generally limited to debts that are directly connected with Spanish assets.

A Spanish mortgage can therefore be relevant. If a non-resident buyer finances a property with a mortgage secured against the Spanish property, the outstanding qualifying debt may reduce the net taxable value used for wealth tax.

• Mortgage debt used to acquire or invest in the Spanish property
• Charges or encumbrances that directly reduce the value of Spanish assets
• The general €700,000 allowance for non-residents
• Regional rules where the taxpayer can apply the autonomous community’s legislation
• Business asset exemptions, where strict conditions are met
• Specific exemptions for certain assets, depending on the facts

Equity release on a high-value Spanish property may, in the right circumstances, form part of legitimate wealth tax planning. It should not be viewed as a simple way to reduce or avoid Spanish wealth tax. The structure must have commercial substance, such as a genuine financing or investment rationale, and should be reviewed by Spanish tax and legal advisers before implementation.

Where borrowing is properly structured, debt secured against a Spanish property may be relevant to the net taxable value of that asset. However, the released funds may need to be held outside Spain, potentially through an international private bank, for the planning to work as intended. If the funds remain in a Spanish bank account, or are otherwise treated as Spanish assets, the debt may reduce the property value but the cash may still be included in the Spanish wealth tax calculation.

This approach is usually more relevant for higher-value properties, particularly from around €2 million upwards. WPC has access to a network of international private banks and can help clients explore whether equity release may be commercially appropriate alongside Spanish tax, legal and cross-border advice.

Spanish wealth tax is calculated by identifying taxable Spanish assets, deducting qualifying liabilities, applying the relevant allowance, and then applying the correct progressive tax scale.

1. Identify all Spanish assets held on 31 December.
2. Value each asset under the Spanish wealth tax rules.
3. Deduct qualifying debts directly connected with those assets.
4. Apply the relevant personal allowance, usually €700,000 for non-residents.
5. Apply the applicable state or regional tax scale.
6. Deduct any applicable reliefs, credits or regional deductions.
7. Check whether the solidarity tax also applies.

The calculation is progressive. This means each slice of taxable wealth is taxed at the rate for that band, rather than the full taxable base being taxed at the highest rate.

Spanish wealth tax planning depends on ownership, finance, asset location and residence status. The following use cases show the types of issues non-resident buyers should review before completion.

A non-resident buyer who uses a Spanish mortgage may be able to deduct qualifying debt connected with the Spanish property. This can reduce the net taxable value of the asset for Spanish wealth tax purposes. The mortgage should be reviewed before completion so the buyer understands both the lending position and the possible tax effect.

A non-resident couple buying a Spanish property jointly may each have their own ownership percentage and personal allowance. This can materially affect the final calculation. Ownership shares should be reviewed alongside succession planning, mortgage eligibility and tax advice before contracts are signed.

An owner of a higher-value Spanish property may consider releasing equity for liquidity, investment or wider financial planning reasons. The borrowing needs a commercial rationale and careful structuring. Where the released funds are held is critical, because funds retained in Spain may still be treated as Spanish assets.

A non-resident with assets in more than one autonomous community should review which regional rules apply. The relevant region can affect rates, allowances, deductions and bonuses. This is particularly important for owners with property in areas such as the Balearic Islands, Costa del Sol, Madrid, Catalonia, Valencia or the Canary Islands.

Spanish wealth tax is partly regional. Autonomous communities can set different allowances, rates, deductions and bonuses. This is why the same asset value can produce different outcomes depending on where the property is located.

For non-residents, regional rules can be especially important because non-residents may have the right to apply the legislation of the autonomous community where the highest value of their Spanish assets is located.

This matters for buyers considering areas such as the Balearic Islands, Costa del Sol, Madrid, Catalonia, Valencia and the Canary Islands. A buyer purchasing in Mallorca may face a different calculation from a buyer purchasing in Marbella or Valencia, even if the purchase price is similar.

Regional rules should be checked each year before filing, especially where a buyer owns assets in more than one Spanish region.

The Comunidad Valenciana has its own wealth tax scale. The Spanish Tax Agency’s 2025 manual shows the following rates for taxpayers resident in the region during that year. Non-resident application of regional rules should be confirmed with a Spanish tax adviser, particularly because the applicable allowance can differ depending on the taxpayer’s position.

The Comunidad Valenciana also increased its general exempt minimum to €1,000,000 for 2025, but the Spanish Tax Agency manual states that the €700,000 minimum remains applicable to taxpayers subject to real obligation, which is the usual position for non-residents.

The Temporary Solidarity Tax on Large Fortunes, known in Spain as Impuesto Temporal de Solidaridad de las Grandes Fortunas, applies to individuals whose net wealth exceeds €3 million.

This tax was introduced as a state-level complement to wealth tax. It is particularly relevant where regional wealth tax reductions or bonuses would otherwise reduce the amount payable. It can affect both residents and non-residents, depending on the taxpayer’s assets and filing position.

For non-resident property buyers, the solidarity tax becomes relevant where Spanish net assets are sufficiently high. It should be reviewed alongside wealth tax, not separately, because wealth tax paid may affect the final solidarity tax position.

Spanish wealth tax is filed using Modelo 714. For the 2025 tax year, the filing period runs from 8 April to 30 June 2026. If payment is made by direct debit, the direct debit window is shorter. The Spanish Tax Agency states that non-resident wealth tax returns must be submitted electronically.

The Temporary Solidarity Tax on Large Fortunes is filed separately using Modelo 718. The Spanish Tax Agency confirms that the 2025 Modelo 718 filing period begins from 1 July 2026, following the update to the form for the 2025 exercise.

Missing a filing deadline can lead to penalties, interest and administrative issues. International buyers should prepare valuation, ownership and mortgage information before the filing period opens.

Spanish wealth tax planning should be part of the purchase strategy. It should not be treated as an annual filing issue only.

• Whether the property will be owned personally, jointly, through a company or another structure
• Whether mortgage finance is appropriate and commercially suitable
• How the property will be valued for wealth tax purposes
• Which autonomous community’s rules may apply
• Whether the solidarity tax could apply now or in future
• Whether Spanish residence could arise from time spent in Spain
• How Spanish tax interacts with the buyer’s home country tax position
• Whether succession, inheritance or gift tax planning should be considered at the same time
• Whether any equity release strategy has genuine commercial substance and appropriate cross-border advice

For many buyers, the right ownership and finance structure depends on more than tax. It should also support family use, succession planning, lending criteria, cash flow and long-term ownership plans.

Spanish wealth tax can affect the true cost of owning property in Spain, particularly for higher-value purchases and non-resident buyers with assets in multiple jurisdictions.
