    Spanish Wealth Tax (Impuesto sobre el Patrimonio) plus ISGF Solidarity Wealth Tax

    Spain levies an annual wealth tax (Impuesto sobre el Patrimonio) on Spanish residents' worldwide net wealth above €700,000 (state allowance), plus a separate primary-residence exemption of up to €300,000. Rates run from 0.2% to 3.5% on a progressive state-level scale. Regional autonomous communities have material variations — Madrid, Andalucía and Galicia have historically applied a 100% bonification (effective zero rate); Catalonia, Valencia, Asturias and others maintain regional schemes that may diverge upward or downward from the state default. In 2022, Ley 38/2022 introduced the ISGF (Impuesto Solidario de las Grandes Fortunas) — a temporary state solidarity wealth tax on net wealth above €3m at 1.7% / 2.1% / 3.5% bands, designed to claw back wealth tax in regions where bonifications had eliminated the regional charge. ISGF offsets against regional wealth tax to avoid double taxation.

    In plain English

    Spain has two parallel wealth taxes. First, the regular Impuesto sobre el Patrimonio (Ley 19/1991) — annual, on worldwide net wealth for residents, with a €700,000 state allowance and a €300,000 primary-residence exemption on top. Rates are progressive up to 3.5%. The headline complexity is REGIONAL: each autonomous community has the legal power to vary the allowance, the rate scale, or the bonification (effective rebate). Madrid and Andalucía have historically applied 100% bonification, eliminating the wealth tax for residents of those regions. Catalonia, Valencia, Asturias, Cantabria, Murcia, Extremadura and others maintain operative regimes that may even exceed the state default. Second, the ISGF (Ley 38/2022) — introduced in 2022 specifically to claw back wealth-tax revenue from residents in regions with 100% bonification. ISGF is STATE level (autonomous communities cannot bonify it away) and applies to net wealth above €3m at 1.7% to 3.5% bands. Crucially, any regional wealth tax paid is credited against the ISGF — so residents in Catalonia (full wealth tax) pay relatively little ISGF, while residents in Madrid (zero regional wealth tax) pay the full ISGF. The political math is deliberate. For UK movers: worldwide assets are in scope from year 1 of Spanish residence (subject to Beckham Law exception — see /moving-abroad/spain/beckham-law-special-regime where wealth tax base is Spanish-situs only during the regime). Modelo 720 disclosures (foreign assets) feed directly into the wealth-tax base.

    How it works

    Scope and valuation

    Spanish residents: worldwide net wealth at 31 December (Spanish-situs only for Beckham Law special-regime taxpayers; see /moving-abroad/spain/beckham-law-special-regime). Non-residents: only Spanish-situs assets. Net wealth = assets minus debts allocable to those assets. Valuation rules: real estate at the higher of cadastral value, AEAT-determined value or acquisition cost; financial assets at year-end market value; insurance policies at surrender value; pension rights generally OUTSIDE the base (a key benefit); business assets meeting the family-business exemption (>5% holding plus management role plus 50%+ personal income from the business) are exempt; primary residence exempt up to €300,000.

    State allowance plus regional variations

    State mínimo exento: €700,000 net wealth. Most autonomous communities adopt this; some vary (Catalonia €500,000; Aragón €400,000 in recent years; check current year). Regional bonifications: Madrid 100% (historical); Andalucía 100% (introduced 2022 in political response to Catalonia); Galicia 100% (recent); some other regions apply partial bonifications. Catalonia, Valencia, Asturias, Cantabria, Extremadura, Murcia, Balearics maintain operative regimes; rates may exceed the state default (Catalonia's top rate is 3.48%; some regions reach 3.75%). Always check current-year regional position — political swings have changed it materially in 2022-2025.

    ISGF — solidarity wealth tax

    Ley 38/2022 introduced ISGF for tax year 2022 onward (initially as a 2-year measure; extended). State-level surcharge on net wealth above €3m: 1.7% (€3m to €5.347m), 2.1% (€5.347m to €10.696m), 3.5% above €10.696m. €700,000 state allowance plus €300,000 primary-residence exemption mirror the regular wealth tax. CRITICAL OFFSET: regional wealth tax paid is credited against ISGF on a euro-for-euro basis — so a Barcelona resident paying full Catalan wealth tax pays minimal ISGF; a Madrid resident paying zero regional wealth tax (100% bonification) pays the full ISGF. The mechanism deliberately neutralises the regional 100% bonification for high-net-worth taxpayers.

    Practical filing — Modelo 714 plus Modelo 718

    Modelo 714: annual wealth-tax return; filing window matches IRPF (typically April to June for the prior calendar year). Obligation to file arises when (a) total gross wealth exceeds €2,000,000 (even where no tax due after exemptions); or (b) tax is due after allowances. Modelo 718: ISGF return, filed July of the year following the tax year. Both filings reconcile against Modelo 720 disclosed assets. Beckham Law taxpayers file Modelo 714 only on Spanish-situs assets during the regime, and ISGF on the same restricted base.

    Common mistakes + traps

    Worked example

    Eleanor, a UK-resident HNW retiree moving to Barcelona in 2026

    Eleanor moves from London to Barcelona on 1 January 2026, becoming Spanish-resident under Art. 9 LIRPF for full calendar 2026. She does not qualify for Beckham Law (no Spanish employment trigger). Her net wealth at 31 December 2026 is €8m, comprising: Barcelona apartment €1.5m (primary residence); UK BTL €0.8m; UK pension drawdown account €1.2m; UK ISA / GIA portfolio €3m; Spanish bank account €0.3m; UK bank account €0.2m; art collection €1m.

    1. Residence: Eleanor is Spanish-resident under Art. 9 LIRPF for full 2026. Worldwide wealth base applies. Catalan autonomous community applies (Barcelona habitual residence on 31 December 2026).
    2. Exemptions: Primary residence €1.5m, exempt up to €300,000 → €1.2m taxable from primary residence. UK pension drawdown account: pension rights are generally outside the base, but the test is whether they are 'consolidated rights in a Spanish-recognised pension plan' — UK pensions are CONTESTED. Conservative practice includes €1.2m. Art collection: typically taxable at insurance value unless of historic/cultural protected status.
    3. Net taxable wealth: €8m total – €300,000 primary-residence exemption – €700,000 state allowance = approximately €7m taxable base. Catalan rate scale applies; computation runs through progressive brackets, with effective combined rate around 1.5% to 2% on this base. Catalan regional wealth tax 2026: illustrative roughly €110,000-€140,000 depending on exact bracket allocation.
    4. ISGF (Modelo 718): net wealth €8m – €300,000 primary-residence exemption – €700,000 state allowance = roughly €7m. Falls into 1.7% (€3m-€5.347m) and 2.1% (€5.347m-€10.696m) brackets. Gross ISGF illustrative roughly €110,000-€130,000. CREDIT: Catalan regional wealth tax paid (≈€110,000-€140,000) credits against ISGF on euro-for-euro basis. Net ISGF likely near zero or low residual.
    5. Net annual cost: ~€110,000-€140,000 Catalan wealth tax; ISGF largely neutralised by the credit. If Eleanor were instead resident in Madrid (100% bonification): Catalan/Madrid regional wealth tax = €0; ISGF = full ~€110,000-€130,000. Net cost similar — the system deliberately equalises HNW residents across regions.
    6. Modelo 720 (mandatory): Eleanor discloses UK BTL, UK pension, UK ISA/GIA, UK bank account (above category thresholds) by 31 March 2027. The disclosed values must reconcile with Modelo 714 wealth-tax valuations.
    7. Modelo 714 (wealth tax return) and Modelo 718 (ISGF) filed during 2027 calendar year for tax year 2026.

    Outcome: Eleanor faces ~€110,000-€140,000 annual Spanish wealth-tax burden as a HNW Barcelona resident, regardless of whether the headline is wealth tax (Catalonia) or ISGF (Madrid scenario). Pre-move planning should consider (a) Beckham Law eligibility if a qualifying activity exists; (b) family-business exemption if holdings can be structured; (c) primary-residence valuation strategy; (d) timing of UK asset disposals before becoming Spanish-resident.

    Frequently asked questions

    What happens if I miss the Self Assessment deadline?+
    The Self Assessment deadline is 31 January (online filing) for the previous tax year. Miss it and HMRC apply an automatic £100 penalty. Beyond that: £10 per day from 3 months late (capped at £900), 5% of tax due at 6 months late, and another 5% at 12 months late, under Schedule 55 of the Taxes Management Act 1970. If you have a genuine reason (serious illness, bereavement, technical issue with HMRC's systems) you can appeal with evidence; HMRC accepts reasonable excuse appeals in most genuine cases.
    Do I need an accountant or can I file Self Assessment myself?+
    Legally you can file Self Assessment yourself via gov.uk for free, most simple sole-trader returns (single income source, basic expenses) are realistic to self-file. An accountant adds real value when: your trading profit is above £40,000 (extraction-strategy decisions matter), you have multiple income streams (PAYE + self-employment + property + dividends), you've crossed the £90,000 VAT threshold, you're considering incorporation, or you have an HMRC enquiry. Expect to pay £400-£1,500/year for a typical sole-trader accountant; the cost is itself a deductible expense.
    How do payments on account work?+
    When your Self Assessment tax bill exceeds £1,000 for the first time, HMRC requires payments on account toward NEXT year's tax. Half the current bill is due 31 January (alongside the current bill); the other half is due 31 July. So your first January after crossing the threshold can hit with a double-bill: last year's balance + first payment on account. Adjust via Form SA303 if you expect next year's income to drop substantially. Payments on account don't apply if more than 80% of your tax is collected via PAYE.
    Can I avoid Spanish wealth tax by moving to Madrid?+
    Partly — Madrid's 100% regional bonification removes the regional wealth tax (Impuesto sobre el Patrimonio), but ISGF (Impuesto Solidario de las Grandes Fortunas) was deliberately introduced in 2022 to neutralise this for net wealth above €3m. A Madrid resident with €5m net wealth pays ~€60,000 ISGF where a Catalan resident pays ~€60,000 regional wealth tax (with ISGF largely credited away). Below the €3m ISGF threshold, Madrid genuinely escapes wealth tax. Above it, the system deliberately equalises.
    Are UK pensions really in the Spanish wealth-tax base?+
    Contested. Art. 4.5 Ley 19/1991 IP excludes 'consolidated rights in pension plans' — but the legislative language anchors to Spanish-style 'planes de pensiones' under Spanish pension law. UK personal pensions (SIPPs, drawdown accounts), UK occupational schemes and UK State Pension entitlements are not Spanish-law pension plans. AEAT practice and successive Constitutional Court analyses have evolved. Conservative practice: include UK pension drawdown account capital values in the base; consider excluding UK State Pension uprating-equivalent capitalised value pending clarity. Specialist advice essential for HNW positions.
    Does Modelo 720 disclosure trigger wealth tax automatically?+
    Modelo 720 is disclosure only — it does not impose tax. But the disclosed asset values feed directly into the Modelo 714 wealth tax base where Spanish residence and threshold conditions are met. AEAT reconciles Modelo 720 disclosures with Modelo 714 filings — material discrepancies trigger review. The 2022 CJEU ruling killed the disproportionate Modelo 720 penalty regime but did not change the substantive wealth-tax exposure on the disclosed assets.
    What's the family-business exemption?+
    Art. 4.8 Ley 19/1991 IP exempts holdings in a 'family business' from the wealth tax base where conditions are met: the holder owns 5% individually (or 20% together with spouse, ascendants, descendants and second-degree relatives); the holder or a relative within the group performs effective management functions; and personal income from the management role exceeds 50% of the holder's total earned and business income. Properly-structured business shareholdings can be wholly exempt — a significant planning lever for HNW residents with active business interests.
