SME Investment: Invest and reduce your taxes

SME investment involves placing savings into the capital of unlisted small and medium-sized enterprises to finance their development and, in some cases, benefit from an income tax reduction. Supporting the real economy while optimizing one's tax situation appeals to an increasing number of investors, but the topic involves precise tax rules, various investment vehicles, and a high level of risk. Here is a comprehensive guide to understanding the IR-PME scheme, its conditions, the different ways to invest in SMEs, and the role of private equity in this asset class.

‍

What is SME Investment?

‍

Investing in an SME means providing equity to an unlisted small or medium-sized enterprise in exchange for a stake in its capital. The investor becomes a partner or shareholder of the beneficiary company and, if successful, benefits from value creation (capital gains on the resale of securities, sometimes dividends). In return, they accept high risk and a long-term commitment of their funds.

This investment serves a dual purpose. On one hand, it finances companies that often struggle to secure funding from banks, particularly young innovative companies and high-growth businesses. On the other hand, it offers investors diversification away from listed markets and, for certain vehicles, a tax advantage in the form of an income tax reduction.

Investment in an SME's capital refers to a cash subscription, meaning a monetary contribution made during the company's formation or a capital increase. It is this cash subscription that, under certain conditions, grants eligibility for the IR-PME tax scheme.

The IR-PME Scheme: Income Tax Reduction

‍

The IR-PME scheme, formerly known as the Madelin reduction, allows taxpayers to deduct a portion of the amounts invested in the capital of eligible SMEs from their income tax. It is one of the main tax incentives linked to business financing, codified in Article 199 terdecies-0 A of the General Tax Code.

‍

‍

In 2026, the standard reduction rate is 18% of contributions for subscriptions to the capital of a classic SME. This rate is increased in specific cases: 25% for subscriptions to the capital of social utility solidarity enterprises (ESUS) and solidarity real estate companies, 30% for Corsican and Overseas FIPs, and up to 30% or 50% for investments in young innovative companies (JEI) depending on their category.

The framework was significantly altered by the 2025 and 2026 Finance Acts. Classic FCPIs and FIPs no longer qualify for the IR-PME reduction; only Corsican and Overseas FIPs, and FCPIs invested in young innovative companies, remain eligible. This change refocuses the scheme on direct financing for SMEs and the most innovative companies. The reduction is declared the year following the investment, by reporting the subscribed amount in the dedicated box on the income tax return.

Conditions for benefiting from the IR-PME reduction

‍

To benefit from the tax reduction requires meeting several conditions, relating to the investor, the beneficiary company, and the holding period.

For the beneficiary company, the SME must notably employ fewer than 250 employees, have an annual turnover of less than 50 million euros (or a total balance sheet of less than 43 million euros), be headquartered in a European Economic Area (EEA) country, and carry out commercial, industrial, craft, or professional activities. The subscribed securities must be shares or units not listed on a regulated market.

For the investor, the reduction applies to cash payments, capped at 50,000 euros for a single person and 100,000 euros for a couple filing jointly. The reduction obtained is subject to the overall cap on tax breaks, set at 10,000 euros per year; the portion of the reduction exceeding this cap can be carried forward for the next five years.

One final key condition: the investor must hold the shares for at least 5 years. Early resale, except in certain cases, leads to the invalidation of the tax benefit, i.e., the clawback of the tax reduction obtained. This tax holding period should not be confused with the actual lifespan of a fund, which is often longer.

Vehicles for investing in SMEs

‍

Several avenues allow for investment in SME equity, with varying levels of diversification and support.

Direct investment involves subscribing to the capital of one or more companies yourself, either as a business angel or through specialized platforms. This is the most hands-on approach: the investor chooses their holdings and can obtain voting rights, but they concentrate their risk on a few companies.

Conversely, investment funds allow for risk diversification across a portfolio of companies. Historically, two types of funds have structured this market for individual investors: FIPs (local investment funds), focused on regional SMEs, and FCPIs (innovation investment funds), which must invest at least 50% of their assets in innovative SMEs (article L.214-30 of the CMF). Since the reform, only certain of these funds remain eligible for IR-PME, as mentioned above.

Beyond tax benefits, private equity is the broadest avenue for investing in unlisted companies, from startups in venture capital to mature SMEs acquired through growth equity. These strategies aim for long-term performance rather than tax reduction.

‍

Why invest in SME equity?

‍

The first benefit is the tax reduction for eligible vehicles, which improves the net return on investment from the moment of subscription. The second is diversification: unlisted investments tend to move partially independently of stock markets, which can reduce the overall volatility of a portfolio. The third is the performance potential: growing SMEs and innovative companies, if successful, offer prospects for capital gains superior to those of traditional investments.

Investing in SMEs also means giving purpose to your savings by financing the real economy, employment, and innovation in a region. Contrary to popular belief, not all SMEs disappear quickly: according to INSEE, approximately 69% of businesses created in 2018 (excluding micro-entrepreneurs) were still active five years later. Nevertheless, the risk remains real and must be thoroughly understood before any commitment.

‍

Risks and limitations of SME investment

‍

Investing in SME equity is among the riskiest investments, and past performance is no guarantee of future results.

The first risk is capital loss: an SME can fail, and the investor may lose all or part of their investment. The second is illiquidity: unlisted securities are not easily resold, and the money is tied up for several years, at least the 5-year tax period, often longer for a fund. The third relates to the management of the company itself, over which a minority investor has little control.

Finally, it's important to remember that tax benefits should never be the sole criterion for making a decision. A tax reduction on an investment that loses value is still a bad deal. The rule is to allocate only a measured portion of one's assets to unlisted investments, consistent with one's investment horizon and risk tolerance.

Private equity: investing in unlisted companies beyond IR-PME

‍

The IR-PME scheme is merely an entry point into the world of unlisted assets. For investors primarily seeking performance and broad diversification, private equity offers a much wider spectrum than tax-advantaged vehicles alone.

French private equity shows a net IRR of 12.4% per year over ten years (France Invest/EY, data as of 12/31/2024), making it the best-performing asset class in the long term, ahead of listed markets. However, this performance is accompanied by significant dispersion among funds and a long capital lock-up period. To learn more, consult our analysis of private equity returns.

Private equity encompasses several strategies: venture capital (startup financing), growth equity, leveraged buyout (LBO) and secondary investments. These strategies invest in SMEs and unlisted companies at different stages of maturity, without relying on the IR-PME scheme. Historically reserved for institutional investors with tickets of several hundred thousand euros, they are now accessible to individual investors through pooling structures.

Fundora: Accessing private equity through discretionary management

‍

Fundora identifies and offers private equity strategies selected for their institutional quality (venture capital, growth equity, LBO, secondary, private debt), structured as FPCI (professional private equity funds) with an SPV (Special Purpose Vehicle) mechanism that pools subscriptions from several individual investors within the same structure. The institutional ticket is thus pooled, and access to unlisted assets is democratized.

Effective management is provided by Kyoseil Asset Management, a portfolio management company approved by the AMF under number GP-99040, within the framework of the mandate. This structure makes leading strategies accessible to individual investors, with multiple objectives that vary according to risk profile (as an objective, without guarantee, past performance is not indicative of future results, and there is a real risk of capital loss).

An important point: the FPCI funds offered by Fundora are not eligible for the IR-PME scheme. They are aimed at informed investors and target performance and diversification, not tax reduction. The IR-PME reduction, on the other hand, concerns direct subscription to the capital of SMEs, FIP Corse and Outre-mer funds, and FCPIs invested in young innovative companies.
