4 Use this skill whenever an individual asks about annual net wealth tax exposure. Trigger on phrases like "wealth tax", "net worth tax", "ISP (impôt sur la fortune immobilière)", "IFI", "patrimoine", "patrimonio", "Vermögensteuer", "Solidaritetsskatt", "formueskatt", "förmögenhetsskatt", "Swiss wealth tax", "Norway wealth tax", "Spain wealth tax", "Spain solidarity tax", "patrimonio extraordinaria", "Madrid wealth tax exemption", "Argentinian bienes personales", "Colombian impuesto al patrimonio", "Uruguay impuesto al patrimonio", or any request to compute net wealth tax. Maps in-force annual net wealth tax regimes as of mid-2025 in Switzerland (cantonal), Norway, Spain (national IP + regional + Impuesto Temporal de Solidaridad), Argentina, Colombia, Uruguay, the Netherlands (Box 3 fictitious yield as wealth-tax-equivalent), and France (IFI on real estate only). Identifies regimes recently repealed (Italy IVAFE/IVIE remain narrow asset-specific; full wealth tax repealed long ago) and proposed wealth taxes (UK, US §2901 proposals, Brazil). Does NOT cover: inheritance / estate / gift tax (see inheritance-estate-gift-matrix), property transfer tax (see property-transfer-tax-matrix), wealth-related taxes on specific assets (Italy IVIE/IVAFE — see Italian skill). ALWAYS read this skill before computing net wealth tax in an in-force jurisdiction.

16## What this file is
17 
18**This file is a content skill that loads on top of `cross-border-workflow-base`.** It maps every in-force annual net wealth tax as of mid-2025.
19 
20**Tax year coverage.** Current for **calendar 2025**, reflecting:
21- **Spain Impuesto Temporal de Solidaridad** extended into 2025 as a temporary national surcharge on net wealth ≥ EUR 3m, neutralising regional rebates (Madrid, Andalucía)
22- **Norwegian wealth tax** rates updated; municipal portion 0.7% + state portion graduated 0.4%/0.6%/1.0%
23- **Swiss cantonal wealth tax** rates by canton with substantial variation (Geneva ~1% top; Schwyz, Nidwalden ~0.2%)
24- **Argentina Bienes Personales** with the new "Plan Aporte Especial" and PPP/Mileiomy-era reductions through Law 27.743
25- **Colombia Impuesto al Patrimonio** as restructured under Law 2277 of 2022
26- **Netherlands Box 3** in transition (constitutional challenge: HR 6 June 2024 effectively forces actual-return based system; transitional law in force 2025 with calculation methods)
27- **France IFI** unchanged (real-estate-only since 2018 replacement of the ISF)
28 
29**The reviewer is the customer of this output.** Wealth tax valuation and exemptions are highly fact-specific. Every output must be reviewed by a credentialed local tax practitioner.

52## Section 2 — Spain
53 
54### 2.1 Three-layer wealth tax stack
55 
56**[T1] Layer 1 — Impuesto sobre el Patrimonio (IP) — national framework + autonomous community administration:**
57- Ley 19/1991 — national law
58- Each Comunidad Autónoma sets rates, brackets, and rebates
59- Effective rates: Catalonia ~0.21-2.75%; Madrid 100% rebate (effectively 0%); Andalucía 100% rebate (effectively 0%); Galicia ~0.2-2.5%; others vary
60- Tax-free minimum (national default): EUR 700,000 (autonomous communities may modify)
61- Habitual residence exemption: EUR 300,000 per taxpayer
62 
63**[T1] Layer 2 — Impuesto Temporal de Solidaridad de las Grandes Fortunas:**
64- Introduced 28 December 2022 (Ley 38/2022) as "temporary" with sunset at end of 2024; **extended through 2025 by RDL 9/2024**
65- National tax on net wealth ≥ EUR 3 million; effectively neutralises regional rebates
66- Rates: 0% to EUR 3m; 1.7% from EUR 3m-5.347m; 2.1% from EUR 5.347m-10.696m; 3.5% above EUR 10.696m
67- Credit for IP paid in the autonomous community
68 
69**[T1] Layer 3 — Combined cap:** total of personal income tax (IRPF) + IP + Solidaridad cannot exceed 60% of IRPF taxable base; cap excluded if assets are mostly non-productive
70 
71### 2.2 Computation example
72 
73A Madrid resident with EUR 8m net wealth:
74- IP at Madrid 100% rebate → EUR 0
75- Solidaridad: (5.347m − 3m) × 1.7% + (8m − 5.347m) × 2.1% = EUR 39,899 + EUR 55,713 = **EUR 95,612**
76- IRPF + Solidaridad capped at 60% of IRPF base
77 
78A Catalonia resident with EUR 8m net wealth:
79- IP at Catalonia top rate ~2.75% above EUR 10.7m (sub-cap brackets apply); estimate IP ≈ EUR 130,000
80- Solidaridad: gross EUR 95,612 − IP paid EUR 130,000 = floor at 0; **net Solidaridad EUR 0**
81- The Solidaridad cancels regional rebate effects
82 
83### 2.3 Exemptions

236 
237## Section 9 — Netherlands — Box 3 (de facto wealth tax via fictitious yield)
238 
239**[T1] Netherlands Box 3 — wealth taxed via deemed yield rather than rate on capital:**
240 
241The **Hoge Raad** judgment of 6 June 2024 confirmed the existing fictitious-yield system unconstitutional where it exceeds actual return. The transitional Box 3 system in force from 2023 onwards (with retroactive cures) computes a deemed yield:
242 
243```
244Deemed yield = (allocated % × yield rate per asset class) − allocated debt × debt yield rate
245Box 3 tax = Deemed yield × 36% (2024/2025 rate, up from 32% in 2023)
246```
247 
248**[T1] Asset class yields (2025 illustrative):**
249- Bank deposits: ~1.03%
250- Other assets (real estate, shares, crypto, foreign accounts): ~6.04%
251- Debt yield: ~2.47%
252 
253**[T1] Tax-free allowance:** EUR 57,000 per taxpayer / EUR 114,000 fiscal partners
254 
255**[T1]** Effective wealth tax rate on "other assets":
2566.04% × 36% = **2.17%** (top range; on actual return-bearing assets that perform below the deemed yield, effective rate is higher)
257 
258**[T2]** Taxpayers can elect actual-yield computation (counter-proof) from 2025; complex documentation required. Permanent reform expected 2027-2028 to align with actual yield.
259

261 
262## Section 10 — Recently changed / proposed
263 
264| Jurisdiction | Status |
265|---|---|
266| **Italy** | No general wealth tax. IVIE (0.76% on foreign real estate) and IVAFE (0.2% on foreign financial assets) remain asset-specific. Long-term ISA proposals for super-rich resurface periodically. |
267| **Germany** | Wealth tax (Vermögensteuer) suspended since 1997 (BVerfG ruling). Periodic SPD/Greens proposals; not in force as of 2025. |
268| **United Kingdom** | No annual wealth tax. Wealth Tax Commission 2020 recommended a one-off 5% wealth tax above £500k; no enactment. 2024 Labour government rejected an annual wealth tax. |
269| **United States** | No federal annual wealth tax. State-level proposals (California AB 259, New York AB 6010); proposed federal Warren/Sanders bills (§2901-2902 ITA) have not advanced. Senator Wyden's billionaire tax (proposed mark-to-market on unrealised gains) is conceptually distinct but related. |
270| **Brazil** | No general wealth tax. CSLL on net profits applies to companies. Proposed Imposto sobre Grandes Fortunas (CF Art. 153 §VII) authorised by Constitution but never enacted. PEC 162/2022 proposal pending. |
271| **Belgium** | No general wealth tax. **Securities Account Tax (Taxe sur les comptes-titres / TCT)** at 0.15% above EUR 1m per holder per account introduced 2021. |
272| **Hungary** | No general wealth tax. Property tax (építményadó) and similar local taxes only. |
273| **Iceland** | Wealth tax (auðlegðarskattur) abolished 2014. |
274| **Sweden** | Wealth tax abolished 2007. |
275| **Denmark** | Wealth tax abolished 1997. |
276| **Finland** | Wealth tax abolished 2006. |
277

279 
280## Section 11 — Cross-border issues
281 
282### 11.1 Worldwide vs territorial scope
283 
284- **Spain, France IFI**: worldwide for residents; Spanish-/French-situs only for non-residents
285- **Norway**: worldwide for residents; Norwegian-situs only for non-residents (limited)
286- **Switzerland (cantonal)**: worldwide for residents (rate determination); cantonal-situs only for non-residents
287- **Argentina Bienes Personales**: worldwide for residents (with foreign-asset surcharge); Argentine-situs only for non-residents
288- **Netherlands Box 3**: worldwide for residents; Dutch-situs only for non-residents
289 
290### 11.2 Double taxation relief
291 
292Few tax treaties contain wealth tax articles. Where present (e.g., OECD Model Article 22):
293- Real estate taxed in the situs state
294- Business property of a PE taxed in the PE state
295- Ships and aircraft taxed in the residence state of the operator
296- All other property taxed in the residence state of the holder
297 
298**[T2]** In practice, double wealth taxation often results because neither state cedes primary right. Foreign tax credits available where bilateral treaty includes Article 22 (e.g., Norway-Switzerland).
299 
300### 11.3 Lex Beckham / impatriate regimes
301 
302- **Spain — Régimen Beckham**: impatriates may opt for non-resident taxation for 6 years; **IP and Solidaridad** still apply on Spanish-situs assets only during election
303- **Italy — Impatriate regime**: income tax preferential; no wealth tax in Italy (n/a)
304- **Portugal — NHR (closed to new applicants 2024)**: no wealth tax
305 
306---
307 
308## Section 12 — Output specification
309 
310The reviewer brief must include:
311 
3121. **Tax base computation** at reference date with asset class valuation methodology
3132. **Debt deduction schedule** with documentation status
3143. **Exemption schedule** per regime
3154. **Rate application** and tax due per regime
3165. **Cap computations** (Spain 60%/income cap; France IFI 75%/income cap)
3176. **Filing schedule** and form references per regime
3187. **Cross-border tax credits** where applicable
3198. **Reviewer questions** — open items flagged as [T2] or [T3]
320 
321---
322 
323## Section 13 — Self-checks
324 
325- [ ] Reference date applied (31 December typical)
326- [ ] All assets valued per regime methodology (FMV vs official assessed value)
327- [ ] Debts only deducted where regime allows
328- [ ] Exemptions for family business / habitual home / pension applied
329- [ ] Rate schedule applied to net taxable wealth (not gross)
330- [ ] Caps applied (Spain 60%; France 75%)
331- [ ] Foreign tax credits considered for double taxation
332- [ ] Filing form and deadline per regime
333- [ ] Output flags every [T2]/[T3] item for reviewer judgement
334 
335---
336 
337## Section 14 — Prohibitions
338 
339- **Do not** assume an asset is exempt because the country generally exempts family businesses — specific tests (≥5% ownership, active role) apply.
340- **Do not** deduct foreign-bank debt against Uruguayan or Spanish wealth tax bases — restrictions apply.
341- **Do not** treat the Madrid 100% IP rebate as eliminating all Spanish wealth tax — the Solidaridad surcharge applies.
342- **Do not** ignore the December 31 reference date — wealth tax is a snapshot, not an average.
343- **Do not** apply ISF rules to French clients — ISF was repealed in 2018; only IFI (real estate only) remains.

About

Use this skill whenever an individual asks about annual net wealth tax exposure. Trigger on phrases like "wealth tax", "net worth tax", "ISP (impôt sur la fortune immobilière)", "IFI", "patrimoine", "patrimonio", "Vermögensteuer", "Solidaritetsskatt", "formueskatt", "förmögenhetsskatt", "Swiss wealth tax", "Norway wealth tax", "Spain wealth tax", "Spain solidarity tax", "patrimonio extraordinaria", "Madrid wealth tax exemption", "Argentinian bienes personales", "Colombian impuesto al patrimonio", "Uruguay impuesto al patrimonio", or any request to compute net wealth tax. Maps in-force annual net wealth tax regimes as of mid-2025 in Switzerland (cantonal), Norway, Spain (national IP + regional + Impuesto Temporal de Solidaridad), Argentina, Colombia, Uruguay, the Netherlands (Box 3 fictitious yield as wealth-tax-equivalent), and France (IFI on real estate only). Identifies regimes recently repealed (Italy IVAFE/IVIE remain narrow asset-specific; full wealth tax repealed long ago) and proposed wealth taxes (UK, US §2901 proposals, Brazil). Does NOT cover: inheritance / estate / gift tax (see inheritance-estate-gift-matrix), property transfer tax (see property-transfer-tax-matrix), wealth-related taxes on specific assets (Italy IVIE/IVAFE — see Italian skill). ALWAYS read this skill before computing net wealth tax in an in-force jurisdiction.
