An OPCI must maintain a mandatory liquidity pocket of at least 5% of assets. This requirement enables the fund to meet investor redemption requests, thus ensuring a certain level of liquidity despite its predominantly real estate composition.

The FCPR is characterised by a minimum quota of 50% of assets invested in unlisted company securities, which distinguishes it from other funds. This requirement reflects its private equity vocation, covering various stages such as venture capital, growth capital, etc.

For an FCPR, the income tax exemption on capital gains at exit is conditional on a minimum holding period of five years. This rule encourages investors to adopt a long-term perspective, consistent with the typical ten-year lifespan of this type of fund.

FCPI offers a 25% income tax reduction on the amount invested in 2025, capped at €3,000 for a single person and €6,000 for a couple. This tax incentive aims to support innovative SMEs, defined by strict criteria such as R&D expenditure representing at least 10% of total costs.

Unlike OPCI, SCPI have an almost exclusively real estate composition (close to 100%), without a significant financial pocket. This specificity explains why their taxation falls entirely under rental income and real estate capital gains.

The 2025 tax reform eliminated the tax reduction for metropolitan FIP, retaining this advantage only for Corsican and Overseas FIP. This measure aims to direct investments towards specific territories with particular financing needs.

The FIP is distinguished by its regional focus (4 neighbouring regions), while FCPR and FCPI have no specific geographic focus. OPCI may have a national or regional dimension depending on its strategy. This classification illustrates how certain AIFs are designed to meet local needs.
