The US Generation-Skipping Transfer Tax is the world's most aggressive GST regime — designed explicitly to prevent dynasties from skipping inheritance tax
The US federal GSTT imposes a flat 40% tax on transfers to persons more than one generation below the transferor (grandchildren, great-grandchildren) — on top of any estate or gift tax already paid. The lifetime GSTT exemption is $13.61m in 2026 (indexed to inflation, doubled by 2017 TCJA, scheduled to revert to ~$7m in 2026 unless extended). The GSTT is designed to prevent wealthy families from using trusts spanning multiple generations (dynasty trusts) to avoid estate tax at each generational transfer. For US persons with European assets or US citizens living in Europe, the GSTT adds a layer of complexity to estate planning that European advisers must understand.

Netherlands penalises generation-skipping with higher rates for grandchildren (18-36%) versus children (10-20%)
Dutch inheritance tax (erfbelasting) applies higher rates to grandchildren than children for the same estate value: children pay 10% (up to €138.642 above exemption) and 20% above; grandchildren pay 18% and 36% respectively — nearly double. This is a direct disincentive to skip a generation in Netherlands succession. The exemption is the same (€23.223) for both. The policy rationale: grandchildren may have already received wealth from their parents; skipping to grandchildren while children are alive implies deliberate tax planning. The practical result: most Dutch families pass wealth to children first, then from children to grandchildren in a later succession.

Italy and Germany provide the most efficient multi-generation transfer in the EU — per-beneficiary exemptions benefit generation-skipping
Italy's €1m per-beneficiary exemption and 4% rate applies equally to children and grandchildren — making direct grandparent-to-grandchild transfer highly efficient for large families. A grandparent with 4 grandchildren can transfer €4m entirely tax-free. Germany provides €200.000 per grandchild (vs €400.000 per child) — but the same progressive rates. In a three-generation family, German planning often involves: grandparent gifts to children (using €400k/10yr), children gift to grandchildren (using €400k/10yr from children), and direct grandparent-to-grandchild gifts (€200k/10yr). The cumulative tax-free transfer across three generations is very substantial.

|---|---|---|---|---|---|
| Italy | €1.000.000 | 4% above | €1.000.000 | 4% above | None — same treatment |
| Germany | €400.000 | 7-30% | €200.000 | 7-30% (same bands) | Moderate — lower exemption |
| Switzerland (Zug) | 0% | 0% | 0% | 0% | None — zero both |
| Spain (Madrid) | €998k equiv 99% bonif | ~0% | Variable by community | Variable | Low in Madrid |
| France | €100.000 | 5-45% | €31.865 | Different schedule | Yes — lower exemption + different rates |
| Netherlands | €23.223 | 10-20% | €23.223 | 18-36% | Yes — double rate bands |
| UK | £325k NRB (estate-level) | 40% | £325k NRB | 40% | None separate — same 40% |
| Belgium (Brussels) | €12.500 | 3-30% | €12.500 | Variable | Moderate |
| USA (federal) | $13.61m lifetime (all) | 40% estate | GSTT €13.61m (shared) | 40% GSTT on top | Major — double 40% possible |
ⓘ Generation-skipping in the Netherlands is the most explicitly penalised in Europe — grandchildren pay 18-36% versus children's 10-20%. Italy treats all direct descendants identically. The US GSTT is a separate additional 40% tax on top of estate/gift tax — making multi-generational US transfers highly expensive without careful trust planning.
Dynasty Trust Planning — Multi-Generation Transfer Strategies
STEP + national tax advisers
| Strategy | Jurisdiction | How It Works | Tax Efficiency | Risk/Limitation |
|---|---|---|---|---|
| Successive wills — G1→G2→G3 | All EU | Standard inheritance at each generation | Each generation pays inheritance tax | Normal — no special planning |
| Direct skip G1→G3 | Netherlands | Grandparent wills directly to grandchildren | Avoids one Dutch inheritance event but higher rate | 18-36% vs 10-20% — depends on timing |
| 10-year gift cycling (Germany) | Germany | Grandparent gifts €200k to each grandchild every 10 years | Systematic tax-free transfer | Must survive 10 years; gifts must be genuine |
| Dynasty trust (US/Channel Islands) | US + offshore | Trust spans multiple generations — no inheritance tax at each generation | Very efficient for large estates | GSTT applies for US persons; offshore jurisdictions may limit duration |
| Life insurance trust (all EU) | UK, Germany, NL, etc. | Policy written in trust skips estate entirely | No inheritance tax on life insurance proceeds in trust | Sum assured only; requires premiums |
| Assurance-vie (France) | France | €152.500 per beneficiary outside estate — includes grandchildren | Better than succession for large amounts | Post-70 premiums less efficient; must name beneficiaries |
| BOR business to grandchildren (Germany) | Germany | Business transferred directly to grandchild-successor | 85-100% BOR exemption + €200k personal | 5-year continuation requirement; lower personal exemption vs child |
ⓘ Dynasty trust planning is primarily a US and Anglo-Saxon concept — most EU civil law jurisdictions restrict trusts spanning more than 2-3 generations. For EU residents, the most efficient multi-generation planning typically involves systematic lifetime gifting (using annual/10-15 year reset exemptions), life insurance, and business succession reliefs — rather than perpetual trusts.

❓ Frequently Asked Questions
A generation-skipping transfer (GST) tax is imposed when wealth passes directly to grandchildren or more remote descendants, bypassing the children's generation. The US has a dedicated federal GSTT at 40% flat rate with a $13.61m lifetime exemption (2026). Most European countries don't have a dedicated GST tax — instead, they handle it through differential rates (Netherlands charges grandchildren double the rate of children) or reduced exemptions (Germany gives grandchildren €200k vs children €400k). Italy treats all direct descendants identically — the most generation-skip-neutral system in Europe.
It depends on the country. In Italy: yes — same €1m exemption and 4% rate for all direct descendants — no penalty for skipping. In Netherlands: no — grandchildren pay 18-36% versus children's 10-20% — skipping is penalised. In Germany: the lower €200k grandchild exemption means it's usually better to pass to children (using €400k exemption), then children pass to grandchildren later (using their own €400k exemption). In the UK: there's no direct benefit to skipping — all beneficiaries pay 40% above the estate-level NRB. Get country-specific advice before structuring a skip.
The US GSTT (Internal Revenue Code §§ 2601-2663) is a 40% federal tax on transfers to persons more than one generation below the transferor (grandchildren, great-grandchildren, or unrelated persons more than 37.5 years younger). It applies in addition to estate and gift taxes — so a large transfer to a grandchild could face both a 40% estate tax AND a 40% GSTT. The lifetime GSTT exemption is $13.61m in 2026 (shared with the lifetime gift tax exemption). US persons with European assets, and non-US persons with US assets, must consider GSTT in their estate planning.
A dynasty trust is a long-duration trust designed to hold assets across multiple generations without triggering inheritance/estate tax at each generational transfer. In the US, some states (South Dakota, Nevada, Delaware) allow perpetual trusts — assets held in trust permanently, with benefits flowing to descendants, without estate tax on each generation's death. The GSTT exemption shelters transfers into these trusts. In Europe, trust law in civil law countries generally limits trust duration, and most EU countries tax trust distributions as they occur. Liechtenstein and Channel Islands foundations/trusts are used as European dynasty-equivalent structures.
France doesn't have a dedicated GST tax, but grandchildren receive a lower personal allowance (€31.865) than children (€100.000) and are subject to a different rate schedule. France's réserve héréditaire protects children — if a grandparent tries to skip a generation entirely, the living children can claim their forced réserve first. Only the quotité disponible (free portion — 25-50% depending on number of children) can be given directly to grandchildren. For French estates, skipping to grandchildren is largely inefficient: lower allowances, potential forced heirship challenges, and a still-living generation of children with legal rights.
