Spain is one of the few European countries that maintains an annual net wealth tax — and one of the fewer still that applies it to non-residents. The *Impuesto sobre el Patrimonio* (IP), governed by Law 19/1991, is assessed annually on the net value of assets located in Spain held by non-residents, regardless of their country of residence. For international investors who own Spanish property, hold shares in Spanish companies or maintain Spanish bank accounts, understanding this tax is not optional: ignorance of it is one of the most common and costly compliance failures encountered by foreign property owners in Spain.
The Real Obligation Basis: What Assets Are in Scope
Non-residents are taxed under the obligación real (real obligation) principle: only assets and rights located, exercisable or enforceable in Spain are subject to IP. The following categories are in scope:
- Spanish real estate, including partial rights such as usufruct or bare ownership.
- Shares in Spanish companies, both listed and unlisted. Unlisted company shares are valued at the greater of: net book value, nominal value, or a capitalised earnings value (profits averaged over three years, capitalised at 20%).
- Bank accounts held at Spanish financial institutions.
- Life insurance policies issued by insurance companies based in Spain.
- Receivables owed by Spanish residents or entities.
- Jewellery, vehicles, boats and private aircraft habitually located in Spain.
Assets used in a business activity carried out directly through a permanent establishment in Spain are generally not subject to IP.
Personal Allowances and Tax Rates
Law 19/1991 grants EU and EEA residents the same €700,000 personal allowance as Spanish residents — a change introduced following European Court of Justice case law that found the exclusion of EU residents from the allowance discriminatory. This means that a French or German resident owning a Spanish holiday home worth €850,000 with no mortgage would have a taxable base of €150,000.
Non-EEA residents — including UK nationals following Brexit, and US, Swiss or other third-country investors — do not benefit from the €700,000 state allowance under the current literal reading of the law. However, subsequent CJEU case law on freedom of capital movement vis-à-vis third countries has created grounds for challenging this differential treatment, and a number of successful administrative and judicial challenges have been brought by non-EEA investors. This remains an active area of litigation.
The state tax scale runs from 0.2% on taxable bases up to €167,129 to 3.5% on amounts exceeding €10,695,996, with eight progressive brackets as set out in Article 30 of the law. Autonomous communities may modify this scale and apply rebates — see below.
The Solidarity Tax: How It Changes the Calculation for High-Value Holdings
Law 38/2022 of 27 December introduced the Impuesto Temporal de Solidaridad de las Grandes Fortunas (ITSGF), which in practice has become a permanent national-level wealth tax on net wealth above €3 million. Rates are: 1.7% (€3-5 million), 2.1% (€5-10 million) and 3.5% (above €10 million).
The ITSGF applies to non-residents on their Spanish-sited assets in the same way as IP. Its most significant practical effect concerns the regional rebate structure:
Several autonomous communities have introduced rebates that effectively zero out IP liability: Madrid offers a 100% rebate, and Andalusia a 99% rebate. These rebates meant that high-net-worth individuals holding Spanish assets in those regions paid near-zero wealth tax. The ITSGF, being a national tax, is not subject to regional rebates, and it operates as a top-up: only the amount by which ITSGF exceeds IP paid is due. The result is that investors relying on Madrid’s 100% rebate are now effectively paying the full ITSGF rate on their Spanish net wealth above €3 million.
This has materially changed the post-tax economics of holding Spanish assets for very high-net-worth individuals and warrants a review of existing structures.
The Fiscal Representative Requirement
Non-residents without a permanent establishment in Spain who hold Spanish assets are required by Article 9 of the Non-Resident Income Tax Law (LIRNR) to appoint a fiscal representative. This representative acts as the interface with the Spanish Tax Agency (AEAT) for IP, Non-Resident Income Tax (IRNR) and other applicable taxes.
The representative bears joint and several liability for the represented person’s tax debts to the extent they fail to fulfil their information and filing obligations. Appointment should be made before any taxable transaction is entered into in Spain and is notified to the AEAT via Form 030 or a census declaration. The appointment of a reliable, professionally qualified representative is not a formality — it is a critical first step in managing Spanish tax exposure effectively.
Planning Strategies for Non-Resident Investors
Several legitimate planning strategies exist to reduce or manage IP exposure for non-resident investors:
Mortgage financing: since IP applies to net wealth (assets minus liabilities), mortgage debt secured against Spanish property reduces the taxable base euro for euro. For a non-resident acquiring a high-value property, leveraged financing serves both a financial and a tax-planning purpose.
Offshore corporate structure: holding Spanish real estate through a non-Spanish company generally eliminates direct IP exposure on the property, though it triggers other considerations: the special levy on Spanish property held by non-resident entities, Non-Resident Income Tax treatment, and the application of the relevant double taxation treaty, some of which include real estate-rich entity look-through provisions.
Asset distribution among family members: spreading asset ownership among spouses and adult children creates multiple personal allowances and lower marginal rate brackets, potentially reducing aggregate IP and ITSGF liability significantly. This planning must be evaluated alongside its Inheritance and Gift Tax implications.
Review of existing structures in light of ITSGF: for investors who structured Spanish holdings to benefit from Madrid’s rebate, the ITSGF has changed the tax arithmetic materially. A structural review — potentially involving a shift from direct real estate holding to a corporate vehicle — may now be warranted for portfolios above €3 million.
All planning decisions must be analysed individually, taking account of the investor’s tax residence, applicable double taxation treaty provisions, and the interaction between IP, ITSGF and Non-Resident Income Tax.
