Owning a higher-value home in Sitges or Barcelona can bring you within Spain's annual wealth tax, which Catalonia applies with a €500,000 personal exemption and rates from 0.21% to 3.48%. Non-residents are taxed only on their Spanish assets, mortgage debt reduces the taxable base, and a couple buying jointly doubles the exemptions. In practice, a non-resident couple buying an unencumbered home below roughly €1,400,000.00 usually pays nothing.
What the wealth tax is and who pays it in Catalonia
Spain's Impuesto sobre el Patrimonio is an annual tax on net wealth, assessed on what you own at 31 December each year. It is a state tax whose revenue and key parameters are ceded to the regions, and the regional differences are large: Madrid rebates the tax so heavily that most residents there pay nothing, while Catalonia collects the tax in full with its own scale and a lower personal exemption than the state default. If the property you are buying is in Sitges or Barcelona, it is the Catalan and state rules described here that determine your exposure.
Spanish tax residents are taxed by personal obligation on their worldwide net wealth. Non-residents are taxed by real obligation — only on assets located in Spain, such as a Sitges home, a Spanish bank account or a car registered here. Your investment portfolio, pension and property outside Spain stay out of the Spanish calculation entirely. By default non-residents apply the state rules, but since Ley 11/2021 all non-residents — not only EU or EEA residents — may opt to apply the rules of the autonomous community where the greatest value of their Spanish assets sits, and choose whichever outcome is better.
One route that no longer works is holding the property through a foreign company. Since Ley 38/2022, unlisted shares in a non-resident entity whose assets are at least 50% Spanish real estate, directly or indirectly, are treated as Spanish-situs assets for wealth tax. A Sitges home owned through an overseas holding structure is therefore generally within the net.
Catalonia's exemptions and rates
Catalonia's minimum personal exemption is €500,000 per taxpayer, lower than the €700,000 state default that most other regions use. On top of that, Spanish tax residents benefit from a main-residence exemption of up to €300,000 per owner on their habitual home. That second exemption is resident-only in practice: a non-resident's Sitges house cannot be their habitual residence for Spanish tax purposes, so it does not apply to holiday or investment homes.
Above the exemptions, Catalonia applies a progressive scale, consolidated in Decret legislatiu 1/2024. The first band charges 0.21% on taxable wealth up to €167,129.45, rising through nine brackets to a top marginal rate of 3.48% on taxable wealth above €20,000,000. To give a sense of scale, a taxable base of €1,000,000.00 after exemptions produces a Catalan wealth tax bill of €5,764.89 — material, but far smaller than many buyers fear at that level.
For non-residents the option matters. The state scale runs from 0.2% to 3.5% with the €700,000 exemption, so at moderate wealth levels the state default is usually more favourable than opting into Catalonia's €500,000 exemption. The comparison should be run each year with your adviser, because the answer changes as values, debt and asset mix change.
How your property is valued — and why the mortgage matters
Article 10 of Ley 19/1991 values real estate at the highest of three figures: the cadastral value, the value determined or checked by the tax administration for other taxes, and the acquisition price including the taxes and costs inherent to the purchase. For a recent buyer, the acquisition price is almost always the highest of the three, so what you paid — plus ITP or VAT, notary and registry costs — is effectively your wealth tax value. Cadastral values in Sitges typically sit well below market, which mainly benefits long-held property.
For purchases completed since 2022, the cadastral reference value (valor de referencia) used for transfer tax can enter the comparison as an administratively determined value, so it is worth knowing that figure before you buy. Our due diligence guide covers how to check it for a specific Sitges property.
Wealth tax is charged on net wealth, so deductible debts reduce the base. A mortgage outstanding against the property at 31 December reduces your taxable wealth euro for euro. For non-residents taxed by real obligation, only debts connected with the Spanish assets — in practice, finance genuinely used to acquire or improve the Spanish property — are deductible. This is why financing decisions made at purchase have a lasting wealth tax effect.
Worked example: a €1,500,000.00 Sitges purchase
Take a non-resident couple buying a Sitges home for €1,500,000.00 with a €600,000.00 mortgage, owned 50/50. Each spouse holds a gross Spanish asset of €750,000.00 and a deductible debt share of €300,000.00, giving each a net Spanish base of €450,000.00 (€750,000.00 − €300,000.00).
That €450,000.00 sits below Catalonia's €500,000 minimum exemption, and below the €700,000 state default they would apply unless they opted otherwise. Taxable base: zero. Wealth tax: zero, for both spouses, under either set of rules. Each spouse's gross Spanish assets of €750,000.00 are also below the €2,000,000 gross-assets threshold, so neither has any obligation to file Modelo 714 at all.
Now remove the mortgage. Each spouse holds €750,000.00 net. Under the state default, €50,000.00 each is taxable above the €700,000 exemption, producing €100.00 each at 0.2%. Under Catalan rules, €250,000.00 each would be taxable, producing €612.01 each — so they would simply stay on the state default. The example shows two things: joint ownership doubles the exemptions, and even where tax arises at this level it is measured in hundreds of euros, not thousands.
The solidarity tax (ITSGF) and the 60% income cap
Above the wealth tax sits the state solidarity tax on large fortunes (ITSGF), created by Ley 38/2022 and extended indefinitely by Real Decreto-ley 8/2023. Its scale charges 0% up to €3,000,000, then 1.7% up to €5,347,998.03, 2.1% up to €10,695,996.06 and 3.5% beyond; a €700,000 reduction, which Real Decreto-ley 8/2023 extended to non-residents as well, means liability in practice begins above €3,700,000.00 of net wealth. It covers residents and non-residents alike, and, crucially, wealth tax actually paid is credited against it. Because Catalonia collects its wealth tax in full at comparable rates, Catalan taxpayers rarely pay much additional ITSGF — the tax was designed to bite in regions that rebate the wealth tax, such as Madrid. Where due, it is filed on Modelo 718 between 1 and 31 July.
Residents also benefit from a cap: the combined wealth tax and income tax bills cannot exceed 60% of the income tax taxable bases, with any excess reducing the wealth tax by up to 80% — a minimum 20% of the wealth tax always remains payable. This cuota íntegra limit was historically resident-only, but Spanish Supreme Court judgments of 29 October and 3 November 2025 (STS 1372/2025 and STS 1402/2025) held that excluding non-residents breaches the EU free movement of capital, opening the cap — and refund claims for earlier years — to non-residents. This is a fast-moving area where specific advice is essential.
Beckham-regime holders and filing basics
If you move to Spain under the Beckham regime (Article 93 of the income tax law), you are treated as a non-resident for wealth tax throughout the regime: real obligation, Spanish-situs assets only. Your overseas wealth stays outside both the wealth tax and the ITSGF, although sufficiently large Spanish assets would still trigger the solidarity tax. Our separate guide to the Beckham law for property buyers covers eligibility and the income tax side.
Filing is on Modelo 714, submitted online alongside the annual income tax campaign. For 2025 wealth, the window ran from 8 April to 30 June 2026 under Orden HAC/277/2026; 30 June is the deadline to plan around each year. You must file if any tax is payable, or — even with a zero bill — if your gross assets and rights exceed €2,000,000. Non-residents count only their Spanish assets against that threshold.
Planning points, and the Sitges price levels where this bites
Three practical points recur. First, joint ownership: two owners means two exemptions, so a 50/50 purchase doubles the tax-free headroom — the standard structure for couples. Second, finance at purchase: a mortgage taken to buy the property reduces the base from day one. Re-mortgaging years later mainly to strip wealth tax value is a different matter: Hacienda scrutinises late equity release, and for non-residents debt not invested in the Spanish asset is generally not deductible anyway. Third, take advice before completion — the ownership split, the financing and any regional-rules option are all cheaper to get right at the outset.
As to when this actually matters in Sitges: a non-resident couple buying an unencumbered home below about €1,400,000.00 stays under two €700,000 state exemptions and pays nothing. A resident couple whose Sitges home is their habitual residence can shelter up to €1,600,000.00 under Catalan rules — (€500,000 + €300,000) per owner — before any tax on the home itself, though their other worldwide assets count too.
Bills become meaningful, rather than nominal, once each owner's net taxable wealth runs well past €1,000,000.00 — typically detached homes in Vinyet, Terramar, Levantina or Can Girona at €2,000,000.00 and above, or buyers with substantial other Spanish assets. At those levels, modelling the wealth tax alongside purchase costs and annual income taxes belongs in the pre-offer numbers, not the post-completion surprises.

Frequently asked questions
Do non-residents pay wealth tax on a Sitges home?
Only on Spanish assets, under the real obligation rules. A non-resident owning a Sitges home is assessed on its net value after deducting the mortgage used to buy it, with a €700,000 personal exemption under the default state rules (or €500,000 if they opt into Catalan rules). A couple owning 50/50 gets two exemptions, so most purchases below €1,400,000.00 without a mortgage produce no wealth tax at all.
How is property valued for Spanish wealth tax?
At the highest of three figures under Article 10 of Ley 19/1991: the cadastral value, any value determined or checked by the tax administration, and the acquisition price including purchase taxes and costs. For recent buyers the acquisition price is almost always the highest, so what you paid effectively sets your wealth tax value. Sitges cadastral values usually sit well below market, which mainly benefits long-held homes.
Does a mortgage reduce Spanish wealth tax?
Yes. Wealth tax is charged on net wealth, so a mortgage outstanding at 31 December reduces the taxable base euro for euro. For non-residents, only debt connected with the Spanish asset — in practice, finance used to acquire or improve the property — is deductible. Taking the mortgage at purchase is straightforward; re-mortgaging later purely to reduce wealth tax attracts Hacienda scrutiny and often fails the deductibility test.
At what property price does wealth tax start in Catalonia?
For a non-resident couple owning 50/50 with no mortgage, tax begins once the home exceeds roughly €1,400,000.00 — two €700,000 state exemptions. A resident couple can shelter up to €1,600,000.00 of their habitual home under Catalan rules, combining the €500,000 personal and €300,000 main-residence exemptions each, though their other worldwide assets also count. Even above these lines, initial bills are typically hundreds of euros per year.
What is Modelo 714 and when is it due?
Modelo 714 is Spain's annual wealth tax return, filed online alongside the income tax campaign with a 30 June deadline — the 2025 return window ran from 8 April to 30 June 2026. You must file if any wealth tax is payable, or if your gross assets and rights exceed €2,000,000 even when no tax is due. Non-residents count only their Spanish assets towards that threshold.
