Why GFIs Are Attracting High-Net-Worth Investors in 2026

In a French fiscal environment characterised by relentless pressure on high earners — the new CDHR surcharge at 20% above €250,000 in reference taxable income, social contributions on investment income rising to 18.6%, and increasing taxation on holding structures — wealth managers are systematically searching for real assets capable of simultaneously reducing current taxation, IFI wealth tax exposure and succession costs.

The Groupement Forestier d’Investissement (GFI) addresses all three objectives at once. Created by the 2014 Agricultural Future Act and regulated by the AMF as an Alternative Investment Fund (AIF), the GFI gives retail investors collective access to French forest ownership, while benefiting from the same exceptional tax treatment historically reserved for family-owned Groupements Fonciers Forestiers (GFF). France’s forests — the third largest in Europe at 17 million hectares — represent a tangible, inflation-resilient asset class that is largely uncorrelated with financial markets.

In 2026, growing demand for ecological niches (carbon credit markets, the Climate and Resilience Act), sustained forest land appreciation (+4% per year on average over a decade according to the French Silviculturists Group), and intensifying domestic tax pressure all reinforce the strategic relevance of this vehicle for portfolios above €1.3M.

The 18% Income Tax Reduction at Subscription

Subscribing to units of an AMF-regulated GFI qualifies for an 18% income tax reduction on the amount invested, under the “IR-PME” scheme applicable to eligible alternative investment funds (Article 199 terdecies-0 A of the General Tax Code). This reduction applies directly against tax owed, with no sector-specific cap for GFIs, within the general annual cap on tax niches (€10,000 per year).

Separately, contributions under the DEFI Forêt scheme (forestry works, insurance, association dues, land acquisitions) also attract an 18% reduction within a dedicated envelope: €5,700 for a single taxpayer, €11,400 for a couple. A couple investing €60,000 in GFI units therefore realises an immediate tax saving of €10,800 — an 18% “dry return” from year one, before any appreciation of the underlying forest assets.

Holding condition: units must be retained for a minimum of five years from subscription to preserve the tax reduction. In practice, given the illiquid nature of the asset, managers recommend a 10 to 15-year horizon to maximise overall returns.

IFI and Succession: 75% Abatements With No Cap

This is arguably the most powerful argument for substantial estates: GFI units benefit from a 75% exemption on the IFI wealth tax base, provided the fund holds a sustainable management plan (Plan Simple de Gestion or equivalent). For a forest portfolio worth €500,000, only €125,000 enters the taxable base, saving up to €875 per year for a taxpayer at the 0.70% marginal IFI rate. Over twenty years, this cumulative saving represents a meaningful contribution to the overall return calculation.

For succession, the Monichon regime (Article 793 of the General Tax Code) applies automatically to forests, woodlands and forestry fund units: heirs benefit from a 75% abatement on inheritance duties, with no cap on value. Unlike the Dutreil Pact — which is limited to operating companies and subject to strict professional activity and retention conditions — the Monichon regime applies automatically to GFI units as long as the beneficiaries commit to 30 years of sustainable management, formalised through a simple notarial declaration.

A concrete example: a couple transferring €600,000 in GFI units to two children reduces the taxable succession base to €150,000 after the Monichon abatement. Applying standard allowances (€100,000 per child per parent), inheritance duties are nearly zero — compared with nearly €60,000 for a comparable conventional property asset.

Forestry Income: A 76% Flat-Rate Deduction

Income from timber harvesting and sales falls under a specific, highly favourable tax regime: by opting for the flat-rate forestry regime, GFI unit holders benefit from a 76% deduction on timber sale proceeds. Only 24% of revenues are included in the income tax base, with social contributions applying to the same reduced figure.

For a taxpayer in the 41% income tax bracket, the effective tax rate on forestry income falls to approximately 14.3% (41% × 24% = 9.8% income tax + 4.5% reduced social contributions) — less than half the 31.4% flat tax applicable to conventional investment income. This differential is particularly significant in 2026, as social contributions on capital income have been raised to 18.6%.

In terms of gross yield, GFIs produce moderate returns: between 1.5% and 3% per year from current income (timber, rural leases, cork), complemented by forest land appreciation (estimated at +3% to +5% per year over a decade, in hedonic pricing terms). The case for GFIs rests not on current yield but on capital preservation, tax efficiency and optimised succession.

Due Diligence and Key Risks

GFI investing is not without risk, and manager selection largely determines long-term outcomes. Three areas of vigilance should guide the due diligence process.
