For years, High-Net-Worth (HNW) Americans moving to France enjoyed a relatively simple wealth tax regime: the Impôt sur la Fortune Immobilière (IFI), which targeted only real estate. However, as we move into 2026, the fiscal landscape is shifting beneath our feet. The French government is transitioning to the Impôt sur la Fortune Improductive (IFI 2.0)—a broader levy designed to penalize capital that doesn't actively fuel the "real economy."
Key Insight for 2026
The 2026 French wealth tax pivot marks the end of the 'real estate only' era. If your net wealth exceeds €1.3 million, you must now inventory digital assets, luxury goods, and even certain life insurance cash balances that were previously exempt.
At Blue Door France, we are tracking the legislative ripple effects of the 2026 Finance Act closely. While the transition faced procedural delays in late 2025, the blueprint for the unproductive wealth tax is clear. For Americans, the clock is ticking to audit their global portfolios before the May 2026 reporting season.
⚖️ From Real Estate to 'Idle' Capital: The New Thresholds
The core philosophy of the 2026 reform is to move capital from "passive" to "productive." The historical entry threshold remains at €1.3 million of net taxable assets. However, the calculation has changed significantly.
Old IFI Rules
- • Only real estate assets included
- • Progressive rates: 0.5% to 1.5%
- • Crypto and luxury goods exempt
New 2026 Rules (IFI 2.0)
- • Real estate + "unproductive" assets
- • Flat 1% rate once over €1.3M threshold
- • Includes crypto, yachts, jets, and jewelry
The Trigger Point
Once your total unproductive wealth crosses the €1.3 million mark, you are taxed on everything starting from the first €800,000. It is a 'cliff' threshold that requires careful valuation of global assets.
💎 Inventorying 'Unproductive' Assets
What exactly does the French tax office consider "unproductive"? For the 2026 fiscal year, the definition has expanded to include assets that were formerly excluded under the IFI. If you are a US citizen living in France, your inventory must now include:
🪙 Digital Assets & Crypto
For the first time, Bitcoin, Ethereum, and stablecoins are explicitly categorized as unproductive wealth. The French government views these as speculative stores of value rather than economic investments.
- Value determined on January 1st exchange rates.
- Includes assets held on both US exchanges (Coinbase/Kraken) and private cold wallets.
🚤 Luxury Goods (Sumptuary Assets)
Movable assets are back on the table. This includes items previously excluded since the abolition of the old ISF in 2018.
- Yachts, pleasure boats, and private aircraft.
- Luxury vehicles and high-end jewelry/precious metals.
- Works of art and antiques (unless designated as museum-quality cultural heritage).
📉 "Sleeping" Cash & Euro Funds
Even your savings are scrutinized. There is now a critical distinction between different types of life insurance (Assurance Vie) holdings.
- Taxable: Fonds Euro (guaranteed capital funds) are deemed unproductive.
- Exempt: Unités de Compte (unit-linked funds) are exempt if invested in corporate equity.
🏢 The Holding Company Trap: 20% Tax
Many American expats use holding companies (French or foreign) to shelter assets. The 2026 Finance Act introduces a aggressive measure against "Cash Box" companies. If you own more than 50% of a company with over €5 million in assets, you face a new risk.
🚨 The 'Sumptuary' Asset Penalty
Under the new 2026 rules, holding companies will be taxed at 20% of the market value of "non-professional" luxury assets they own. This targets corporate-owned:

🛡️ The 5-Year Safe Harbor for Americans
There is a critical "shield" for new arrivals. Under Article 964 of the French Tax Code, the Impatriate Exemption provides a five-year grace period for wealth tax purposes.
| Asset Type | Year 1-5 in France | After Year 5 |
|---|---|---|
| French Real Estate | Taxable | Taxable |
| US Real Estate | Exempt | Taxable |
| Global Crypto/Jewelry | Exempt | Taxable |
