Poland's Group 0 immediate-family exemption is one of the most generous in Europe — spouse, descendants, ascendants, and siblings can inherit unlimited amounts tax-free, provided the proper notification is filed within six months. That domestic generosity ends at the Spanish border. Spanish IHT applies to Spanish-situs assets and, for Spanish-resident heirs, to worldwide assets, regardless of how Poland treats the same transfer.
Poland has one of the largest expat populations in Spain outside the UK and Germany, and the community continues to grow. Polish professionals working in Madrid and Barcelona, Polish families on extended postings, Polish retirees increasingly choosing the Costa del Sol over traditional Polish destinations — all bring with them a Polish legal and tax framework very different from Spain's.
Polish inheritance tax (podatek od spadków i darowizn) is codified in the Ustawa o podatku od spadków i darowizn of 28 July 1983, with material amendments in 2007 introducing the Group 0 zero-rate category for immediate family. Rates for Group 1 (spouse, descendants, ascendants, siblings, in-laws) are 3%–7% above a €10,434 allowance; Group 2 (further relatives) 7%–12% above €7,878; Group 3 (unrelated) 12%–20% above €5,308. Group 0 — the narrower Group 1 core of spouse, descendants, ascendants, siblings, and stepchildren — is completely exempt, subject to a six-month filing obligation on form SD-Z2.
There is no inheritance tax treaty between Poland and Spain. Spain's only IHT treaties are with France (1963), Italy (1977), and Germany (1966). Relief between Poland and Spain flows through unilateral mechanisms: Poland does not have a foreign-tax credit under its own PSD statute (Poland typically exempts rather than credits), and Spain applies its own unilateral credit under Article 23 Ley 29/1987. For Group 0 Polish heirs, this is rarely relevant — the Polish side collects nothing.
Polish succession law protects descendants, the surviving spouse, and in limited cases parents through zachowek (forced share), codified in Articles 991–1011 of the Kodeks cywilny. Entitled heirs can claim half of what they would have received on intestacy, rising to two-thirds for minors or permanently incapacitated heirs. Unlike Spanish legítima, zachowek is a claim right in cash — the entitled heir cannot demand a specific asset, only the monetary value. Under Brussels IV (EU Regulation 650/2012) a Polish national habitually resident in Spain can elect Polish law to govern succession.
This page explains how Polish and Spanish rules interact, how the Group 0 exemption works in practice, when Brussels IV election of Polish law is the right move, and how Platinum Legal Spain designs Polish-expat estate plans that preserve the Polish domestic position while neutralising Spanish exposure through regional bonificaciones. It covers Polish residents with Spanish holiday homes, Polish professionals in Madrid and Barcelona, mixed Polish–Spanish families, and Polish business owners with cross-border holdings.
Polish estate planning in Spain runs on four pillars: Poland's Group 0 exemption at home, Spanish IHT on Spanish-situs assets, no bilateral treaty, and Spanish regional bonificaciones as the primary relief on the Spanish side.
Article 4a of the Polish PSD Act exempts transfers to spouse, descendants, ascendants, siblings, and stepchildren entirely — unlimited amount — provided form SD-Z2 is filed with the Polish tax office within six months of the notary certificate or court ruling confirming inheritance.
Polish tax positionRelief flows through unilateral Spanish credit only (Article 23 Ley 29/1987), capped at the Spanish IHT attributable to the foreign asset. For Group 0 heirs, there is no Polish tax to credit — Spain collects its full IHT on Spanish assets.
How the unilateral credit worksEU Regulation 650/2012 lets a Polish national habitually resident in Spain elect Polish law to govern succession. Zachowek stays in place; Spanish legítima is displaced. The Polish notarial system (testament notarialny) interacts cleanly with Brussels IV elections.
Polish-law election draftingKodeks cywilny Articles 991–1011 reserve half of the intestate share for descendants, spouse, and parents (two-thirds for minors or permanently incapacitated). Zachowek is a monetary claim, not an asset allocation — different from Spanish legítima's mandatory property distribution.
Forced heirship coordinationSince the 2014 ECJ ruling, Polish EU-national heirs access Spanish regional bonificaciones on the same terms as Spanish residents. Andalusia 99%, Madrid 99%, Valencia 99% Group I/II, Murcia 99%. Plan around the autonomous community of the Spanish asset.
Regional planningPolish marriages default to wspólność majątkowa małżeńska (community of property acquired during marriage) under Article 31 Kodeks rodzinny. On death, the surviving spouse already owns half of community assets — reducing the estate subject to both Polish and Spanish IHT calculations.
Marital property planningThe Polish Group 0 exemption is unique in Europe for its unlimited scope combined with its strict procedural requirement. The exemption is not automatic — it depends on timely filing of form SD-Z2 with the Polish urząd skarbowy within six months of the notarial or court certificate confirming inheritance rights. Missing this deadline pushes the heir into the normal Group 1 bracket (3%–7% above €10,434), with no retrospective restoration of the exemption except through a narrow notariuszowskie (notarised) gift route that has its own requirements.
Wspólność majątkowa małżeńska — the Polish default community of property regime — means that in most Polish marriages without a prenuptial agreement (intercyza), each spouse already owns half of the assets acquired during the marriage. On death, only the deceased's half passes through succession. This halves the Polish podatek od spadków base and, importantly, halves the Spanish IHT base on worldwide assets where the deceased was Spanish-resident. The Spanish notary must recognise the Polish community property characterisation on the inventario — we document this in advance.
Zachowek is a cash claim. If the Polish deceased leaves everything to the surviving spouse, a disinherited descendant can claim half of the intestate share in money — not a specific asset. This makes Polish forced heirship much more flexible for the testator than Spanish legítima, which requires an asset-by-asset allocation. Brussels IV election of Polish law preserves this flexibility, which is often a decisive advantage for Polish business families.
We confirm Polish and Spanish tax residence, map assets by situs, identify community vs separate property under Polish matrimonial rules, and determine which state has primary taxing rights under unilateral rules.
We draft a Polish will (typically testament notarialny at a kancelaria notarialna) with a Brussels IV election of Polish law, and a Spanish will limited to Spanish assets deferring to the Polish-law election. Zachowek calculations are documented in the Polish will.
We model Polish podatek od spadków (usually zero for Group 0), Spanish national IHT, the regional bonificación applicable to the Spanish property, and the Spanish unilateral credit. For Group 0 heirs, Spain collects without Polish offset.
We handle the Polish notarial akt poświadczenia dziedziczenia or court stwierdzenie nabycia spadku, file the Group 0 SD-Z2 within six months, handle Spanish Modelo 650 within six months, and coordinate cross-border bank and property registrations.
Polish inheritance and gift tax is governed by the Ustawa o podatku od spadków i darowizn of 28 July 1983 (with major amendments introducing Group 0 on 1 January 2007 via the Ustawa z dnia 16 listopada 2006 r.). The tax applies to inheritances and gifts received by Polish residents anywhere in the world, and to inheritances of Polish-situs property received by non-residents. The deceased's residence matters for Poland only indirectly — the tax is assessed on the heir, not the estate.
Tax groups: Group 1 (najbliższa rodzina — spouse, descendants, ascendants, siblings, stepchildren, in-laws) allowance €10,434, rates 3%/5%/7% in bands. Group 2 (zstępnych rodzeństwa, dalsze powinowactwo) allowance €7,878, rates 7%/9%/12%. Group 3 (unrelated) allowance €5,308, rates 12%/16%/20%. The allowance is calculated over five years (per heir per donor), meaning cumulative gifts and inheritances from the same donor within a rolling five-year window are aggregated.
Group 0 under Article 4a is a subset of Group 1: spouse (małżonek), descendants (zstępni), ascendants (wstępni), stepchildren (pasierbowie), siblings (rodzeństwo), and stepparents (ojczym, macocha). It does not include in-laws, even though they are Group 1. The exemption is unlimited in amount but conditional on: (a) filing form SD-Z2 within six months of the event (the notarial certificate or court ruling); (b) for cash transfers, documentary evidence of bank transfer or postal order. Missing either condition drops the heir back to Group 1 rates.
Zachowek (Kodeks cywilny Articles 991–1011) is structurally different from Spanish legítima in four respects: (1) it is a cash claim, not an asset allocation; (2) it is triggered only if the entitled heir did not receive their reserved share — there is no automatic allocation; (3) the claim is against the heirs or beneficiaries, not the estate as such; (4) the limitation period is five years from the opening of succession. Descendants, the surviving spouse, and (where there are no descendants) parents are entitled to zachowek equal to half of the intestate share, rising to two-thirds for minors or permanently incapacitated claimants.
Wspólność majątkowa małżeńska (Kodeks rodzinny i opiekuńczy Article 31) is Poland's default marital property regime. Unless couples execute an intercyza (prenuptial contract) before a notary, all assets acquired during the marriage (other than specific excluded categories — inheritances, gifts to one spouse, pre-marriage property) are owned jointly as wspólność łączna (joint community). On death, the community terminates and the surviving spouse is recognised as owner of half of community assets. Only the deceased's half enters the succession.
Polish succession procedure runs through the notariusz (notary public) or the sąd rejonowy (district court). The akt poświadczenia dziedziczenia (notarial certificate of inheritance rights) is the fast route — requires all heirs present, typically 30-60 days. The court stwierdzenie nabycia spadku (court inheritance ruling) is the slower route — 3-12 months depending on the court. Both are valid for Spanish purposes once apostilled under the 1961 Hague Convention and translated by a traductor jurado.
For Polish residents owning Spanish property, the planning stack is: (1) wspólność majątkowa halves the estate base if the asset was acquired during the marriage without intercyza; (2) Polish podatek od spadków is assessed on the deceased's half at Group 0 zero rate (if SD-Z2 filed); (3) Spanish IHT is assessed on the full Spanish-situs value (Spain applies its own régimen económico matrimonial analysis — we argue separation of property or community of property depending on family structure); (4) Spanish regional bonificación reduces the Spanish liability for Group I/II heirs; (5) Spanish unilateral credit offsets any Polish tax paid (usually zero).
Polish pension death treatment: ZUS (Zakład Ubezpieczeń Społecznych) survivor pensions are outside podatek od spadków. Pracownicze plany kapitałowe (PPK) and IKZE (indywidualne konto zabezpieczenia emerytalnego) death benefits paid to nominated beneficiaries are outside podatek od spadków up to specific limits. For Spanish-resident deceased, Spain includes these amounts in the IHT base — Poland does not tax, Spain does.
Polish business succession: Article 4b of the PSD Act provides a zero rate on family business transfers where the heir continues the business for at least two years and is Group 0. The Spanish 95% reduction under Article 20.2.c Ley 29/1987 can apply alongside for Spanish business assets. Polish family businesses often use a zarząd sukcesyjny (succession manager) appointment under the 2018 law to maintain business continuity during inheritance proceedings — a valuable cross-border planning tool.
Polish residents moving to Spain under Beckham Law (Article 93 LIRPF) face the same worldwide-IHT flip as other nationalities. Entry and exit planning, Polish and Spanish will drafting, Brussels IV election, and wspólność majątkowa positioning must be coordinated before Spanish civil residence triggers. Polish-Spanish banking (particularly through Santander's Polish subsidiary network) facilitates asset tracing and AEOI/CRS compliance.
Intercyza use is less common in Poland than in some other EU jurisdictions but is growing among international families. For a Polish–Spanish mixed couple, an intercyza executed before marriage (or supplemented later) can exclude Spanish property from wspólność majątkowa — which reshapes both the Polish and the Spanish succession calculations. This is a drafting question that benefits from coordinated Polish and Spanish input.
Group 0 exemption is unlimited in Poland. Nothing of the kind exists in Spain. Regional bonificaciones fill the gap — but only if the plan captures them.

Polish sp. z o.o. parent, Spanish SL subsidiary. Zarząd sukcesyjny appointed for Polish side; Brussels IV election of Polish law; Spanish 95% family business reduction on SL shares; Article 4b Polish relief on parent shares. Coordinated business continuity.
The Group 0 exemption is lost if SD-Z2 is not filed within six months of the notarial certificate or court ruling. Polish heirs resident abroad frequently miss this because the Spanish Modelo 650 deadline dominates attention. Both deadlines must be tracked.
Polish marriages default to community of property unless an intercyza exists. Skipping the community analysis overstates the estate by up to 100% on both Polish and Spanish sides. Spanish notaries and gestores routinely miss this.
Group 0 under Article 4a includes spouse, descendants, ascendants, siblings, and stepchildren — not in-laws, nor cousins, nor nephews and nieces. These fall under Group 1 or 2 with allowances and rates.
Zachowek is a cash claim against the beneficiaries, not an asset allocation. Spanish legítima is a mandatory property distribution. Brussels IV election of Polish law converts the Spanish mandatory allocation into a Polish cash claim — usually beneficial but must be understood.
Polish allowances are calculated over a five-year rolling window per donor per heir. Multiple gifts or inheritances from the same source aggregate. Group 0 is unlimited so not affected, but Groups 1-3 are materially affected.
ZUS survivor pensions, PPK, IKZE death benefits are outside podatek od spadków but inside Spanish IHT base where the deceased was Spanish-resident. Polish families frequently expect the Polish ring-fencing to carry across.
