Wealth Tax in France 2026: M&A Exit Planning for Founders & Investors

Wealth tax france remains one of the most misunderstood areas of French fiscal law for founders and investors preparing to sell a business in 2026. Many assume the country still imposes a broad tax on total net worth, when in fact the historic impôt de solidarité sur la fortune (ISF) was abolished and replaced in 2018 by a narrower real‑estate levy. For anyone planning an M&A exit, whether a founder selling a majority stake, a private equity manager unwinding a position, or a family office rebalancing after a liquidity event, the practical question is not simply whether the tax exists, but how it interacts with capital gains on share disposals, reinvestment choices, and post‑deal holding structures.

Quick answer, does France still have a wealth tax?

Yes, but not in the form most people imagine. The impôt de solidarité sur la fortune (ISF), which taxed a household’s entire net worth above a threshold, was repealed with effect from 2018. In its place, France introduced the impôt sur la fortune immobilière (IFI), the real‑estate wealth tax. The IFI applies only to real‑estate assets, whether held directly or indirectly through companies and funds. Movable wealth, cash, listed and unlisted shares, bonds, investment portfolios, business equity, is generally outside the IFI base.

For founders, this distinction is decisive. The shares you hold in your operating company are not, in themselves, subject to wealth tax france rules under the IFI. But the moment you sell those shares and convert equity into cash, and then deploy that cash, the character of your wealth can change. If proceeds are channelled into French real estate, an IFI exposure can crystallise where none existed before. The exit therefore does not merely trigger capital gains tax; it can reshape your long‑term wealth‑tax profile. That is why exit planning and wealth‑tax planning must be considered together rather than in sequence.

Wealth tax framework in France 2026, IFI vs historic ISF

Understanding the current wealth tax france regime requires separating what the IFI covers today from what the ISF covered before 2018. The change is not cosmetic: it fundamentally narrowed the tax base and altered the planning calculus for business owners.

What IFI covers (scope and thresholds)

The IFI is a tax on net real‑estate wealth. It captures residential and commercial property, land, and, importantly, the real‑estate value embedded in companies and investment vehicles in which the taxpayer holds an interest. A household becomes liable when the net taxable real‑estate value exceeds the entry threshold set by the Code général des impôts, with the tax calculated on a progressive scale above that threshold. Certain assets qualify for exemption, most notably real estate used for a genuine professional or operating business activity, which can be excluded from the base where the statutory conditions are met.

Reporting is integrated with the income‑tax return for most taxpayers, and the valuation of indirectly held real estate, property owned through holding companies, SCIs (sociétés civiles immobilières) or funds, is where much of the technical complexity lies. The official scope, thresholds and reporting rules are published and periodically updated by the Direction générale des finances publiques, and any numerical figure used in planning should be verified against the current impots.gouv.fr guidance at the time of the transaction.

What ISF covered historically and why the change matters for founders and PE

The ISF was far broader. It taxed the aggregate net worth of a household, real estate, financial investments, business shareholdings not otherwise exempt, and other valuables, above its threshold. For founders and investors, the ISF created a recurring annual charge on illiquid business equity, even where no cash had been realised. The “business asset” (biens professionnels) exemption mitigated this for active founders, but passive investors and family holdings frequently sat within the net.

The switch to the IFI removed movable financial wealth, including shares, whether listed or unlisted, from the wealth‑tax base entirely. For a founder holding a large unrealised stake, this is significant: the equity itself no longer attracts an annual wealth tax. The planning focus has consequently shifted from “how do I shelter my shares” to “what happens to my wealth‑tax position after I sell and reinvest”. For private equity managers and family offices, legacy structures created to manage ISF exposure may now be sub‑optimal, and a review of pre‑2018 holding arrangements is often overdue.

Residence rules and global vs French real estate exposure

Residence governs the geographic reach of the IFI. French tax residents are, in principle, liable on their worldwide real estate, including property held abroad and the real‑estate component of foreign investment vehicles. Non‑residents are liable only on real estate situated in France, including French property held indirectly. Double‑tax treaties and foreign property credits can modify this outcome, so cross‑border founders, and French residents holding overseas assets, must map their global real‑estate footprint carefully. In addition, individuals who become French tax resident after a period of non‑residence abroad may benefit from temporary relief on foreign assets under conditions set by the Code général des impôts.

For anyone contemplating a change of residence around an exit, the interaction between residence timing, treaty protection and the IFI base deserves early, specialist attention.

How wealth tax considerations affect founders and majority shareholders

The wealth tax france analysis changes character on either side of a sale. Before the deal, a founder’s wealth is typically concentrated in illiquid shares; after the deal, it is cash seeking a home. Each state carries different wealth‑tax consequences, and the transition is where planning opportunities, and traps, concentrate.

Pre‑exit wealth profile: unrealised shareholdings, family holdings and real estate exposure

Before an exit, a typical founder’s balance sheet is dominated by operating‑company equity that falls outside the IFI base. Any existing IFI liability usually stems from the family home, investment properties, or real estate held through an SCI or holding company. Family holdings add nuance: shares passed to the next generation, interests held through a holding structure, and property co‑owned across a family group can each carry distinct valuation and reporting consequences.

The key pre‑exit exercise is to produce a clear picture of current real‑estate exposure, separating business‑use property (potentially exempt) from passive investment property (within the base). This baseline matters because it tells you how much of your post‑sale wealth tax france position is already “baked in” versus how much is a function of what you choose to do with the proceeds.

Post‑sale wealth composition and IFI exposures

After a share sale, the proceeds are cash, and cash is outside the IFI base. If a founder simply holds the net proceeds in bank deposits or financial investments, the sale creates no new wealth‑tax liability. The exposure arises from reinvestment decisions. A founder who deploys proceeds into a Paris apartment, a portfolio of rental properties, or a real‑estate fund converts movable wealth into taxable real‑estate wealth, and may cross the IFI threshold for the first time.

This is the central practical insight for business owners weighing a wealth tax france exposure: the sale itself is a capital‑gains event, not a wealth‑tax event; the wealth‑tax consequence is a downstream function of reinvestment. A founder who intends to buy significant French property after exit should model that acquisition into the exit plan, not treat it as a separate, later decision.

Tax on sale of shares, capital gains, PFU, social contributions and interplay with wealth tax france rules

The dominant tax at exit is not the IFI but the taxation of plus‑values mobilières, capital gains on the disposal of shares. Understanding this regime, and how it interacts with the wealth‑tax position, is essential to any exit model.

Capital gains tax basics, PFU vs progressive scale

Gains on the sale of shares by an individual French resident are, by default, subject to the prélèvement forfaitaire unique (PFU), the “flat tax”. The PFU combines a 12.8% income‑tax component and 18.6% in social contributions, for a headline combined rate of 31.4%. The 31.4% flat rate applies to the gross gain without the benefit of certain holding‑period allowances.

Alternatively, eligible taxpayers may elect to be taxed under the progressive income‑tax scale instead of the flat 12.8% component. This option is global, it applies to all of the taxpayer’s investment income for the year, not selectively, and can be advantageous for some taxpayers, particularly where legacy allowances (for securities acquired before 1 January 2018) or a lower marginal rate apply. The choice between the PFU and the progressive scale should be modelled on the specific facts, and the current rules and any transitional allowances should be confirmed against the impots.gouv.fr guidance on plus‑values mobilières.

Social contributions (CSG, CRDS) on share disposals

Regardless of whether the PFU or the progressive scale applies to the income‑tax element, social contributions apply to the gain at the prélèvements sociaux rate, currently 18.6%. These contributions, which include the CSG and CRDS, are a fixed component of the 31.4% flat tax and are also levied where the progressive option is chosen. For high earners, an additional exceptional contribution on high incomes (contribution exceptionnelle sur les hauts revenus) may also apply above the applicable income thresholds. Because social contributions represent more than half of the combined 31.4% charge, they are not a rounding item: they materially affect net exit proceeds and therefore the capital available for any subsequent real‑estate reinvestment that might trigger a wealth tax france liability.

Interaction with the wealth‑tax base, why reinvestment matters

The capital‑gains charge and the IFI operate independently, but they are linked through the net cash a founder retains and how it is deployed. A higher effective capital‑gains rate leaves less to reinvest; a decision to reinvest into real estate converts untaxed movable proceeds into IFI‑taxable wealth. The two taxes should therefore be modelled together: the after‑tax exit figure drives the reinvestment capacity, and the reinvestment mix drives the recurring wealth‑tax france exposure for years afterwards.

M&A exit planning techniques to mitigate wealth tax france impact

Effective exit planning sequences capital‑gains efficiency with long‑term wealth‑tax positioning. The techniques below are options to discuss with counsel, not off‑the‑shelf solutions; each carries conditions, timing requirements and anti‑avoidance considerations.

Pre‑exit restructuring: holding companies, rollovers and reorganisations

Interposing a holding company (a société holding) between the founder and the operating company is a long‑established structuring tool. Where a founder contributes operating shares to a controlled holding company before a sale, French law provides mechanisms, subject to strict conditions, under which the gain on the contribution can be deferred rather than taxed immediately (the apport‑cession regime set out in the Code général des impôts). The proceeds then sit inside the holding company, where financial reinvestment does not create a personal IFI exposure. This can be attractive where the founder wishes to retain and redeploy capital for further investment rather than extract it personally.

The deferral is conditional. The regime typically requires the holding company either to retain the contributed shares for a minimum period, or, where the holding company sells within that period, to reinvest a defined proportion of the proceeds into qualifying economic activity within a prescribed time limit, failing which the deferred gain becomes payable. The statutory tests are set out in the Code général des impôts and must be followed precisely; a holding company created purely to warehouse cash without genuine reinvestment risks losing the benefit of deferral.

Share sales with reinvestment and rollover reliefs

Beyond apport‑cession, certain reinvestment regimes allow all or part of a gain to be deferred where proceeds are reinvested into qualifying assets or activities within a set window. These reliefs reward capital that is recycled into productive investment rather than consumed. The conditions, the proportion that must be reinvested, the qualifying asset classes, and the holding period thereafter, are exacting, and premature disposal of the reinvestment asset can claw back the relief. For founders intending to build a second venture or a portfolio of operating investments, these regimes can align tax deferral with commercial strategy.

Debt, escrow and structured consideration

The structure of the consideration itself affects both cash flow and wealth‑tax timing. Deferred consideration, earn‑outs and escrow arrangements spread the receipt of proceeds over time, which can affect the timing of the capital‑gains charge and delay the point at which cash becomes available for real‑estate reinvestment. Where part of the consideration is held in escrow pending warranty claims, the founder’s realised wealth, and therefore any downstream wealth tax france exposure, may be correspondingly delayed. Vendor financing and rollover equity in the buyer’s structure can likewise keep value in movable, non‑IFI form rather than converting it to taxable property.

The precise tax treatment of earn‑outs and deferred elements should be confirmed with counsel, as the timing of taxation depends on how the consideration is characterised.

Cross‑border considerations for non‑residents and French residents with foreign assets

Cross‑border founders face additional layers. A French resident selling shares and holding property abroad must account for worldwide real estate in the IFI base, subject to treaty relief. A non‑resident founder is taxed only on French‑situs real estate, which can make the location of post‑exit property acquisitions a planning variable. Where a founder contemplates emigration before or after an exit, the interaction between residence timing, the French exit‑tax rules on latent gains (exit tax under the Code général des impôts), and treaty protection must be examined well in advance. Residence planning executed too close to signing rarely achieves its intended effect and can attract scrutiny.

Practical cautions: anti‑avoidance, substance and timing

Every technique above is subject to French anti‑abuse rules, including the abus de droit and the mini‑abus de droit provisions. Arrangements whose principal purpose (or, under the mini‑abus de droit, one of whose principal purposes) is to obtain a tax advantage contrary to the intent of the legislation can be disregarded. Holding companies must have genuine substance; reinvestment commitments must be real and documented; and residence changes must reflect an actual change of circumstances. Timing is equally critical, several reliefs depend on steps taken before the sale is legally committed, so planning initiated after a signed letter of intent may already be too late.

The overriding caution is that these are structuring options to be implemented with specialist advice, not self‑service devices.

Key takeaways and recommended next steps

• France’s wealth tax france regime is the IFI, a real‑estate wealth tax, and movable financial wealth, including shares, sits outside its base.
• A share sale is a capital‑gains event taxed under the PFU (31.4%) or an optional progressive scale; the IFI consequence depends on how proceeds are reinvested.
• Reinvestment into French real estate can create an IFI liability where none existed; financial reinvestment generally does not.
• Rollover and deferral regimes exist but carry strict conditions, substance requirements and timing deadlines.
• Engage specialist tax counsel 6–12 months before an exit, run PFU‑versus‑progressive simulations, and review legacy holding structures.
