How to Optimise Your Wealth in 2026: Method and Trade-offs for Business Owners

Updated 25 May 2026 — Written by Samuel Hayot, chartered accountant (expert-comptable), Paris

The same mistake comes up repeatedly in the client files we manage: buying a product before understanding the situation. A life insurance policy (assurance-vie) is opened because an adviser suggested it. A buy-to-let flat is purchased because it feels tangible. A PER (plan d'épargne retraite — retirement savings plan) is subscribed to cut this year's tax bill without considering what that means at retirement. The result is an accumulated rather than a constructed portfolio — difficult to read, costly to unwind, and frequently misaligned with what the client actually needs.

The method we use is different: diagnosis first, objectives second, product selection last. It takes longer to implement, but it holds over time.

Direct answer: to optimise your wealth in France in 2026, begin with a complete wealth audit, define your objectives by time horizon (liquidity, income, growth, transmission), then select the appropriate tax wrappers — PEA (plan d'épargne en actions), PER, life insurance, dismemberment (démembrement), or a patrimonial holding company — and finally allocate between direct real estate, SCPI funds (sociétés civiles de placement immobilier) and financial assets, factoring in your full tax position: IFI (impôt sur la fortune immobilière), the 30% flat tax (PFU, prélèvement forfaitaire unique), and inheritance costs.

An effective wealth strategy follows four distinct phases:

This sequential logic guards against impulse purchases and contradictions between instruments.

A wealth audit is not simply a list of your assets. It must surface three dimensions that are often overlooked:

• Sector concentration: how much of your net worth is tied to your own business sector (company shares, business premises, trade receivables)? A construction sector director with 80% of net worth in the company and a buy-to-let flat is poorly diversified, even if the overall balance sheet looks comfortable.
• The real cost of exit: gross asset value says little without the tax cost of disposal, inheritance, or policy redemption. A property worth €600,000 may cost €150,000 in tax and fees to exit — that changes the net figure materially.
• Concentration risk: a single life insurance policy of €800,000 with the same insurer simplifies administration but creates a concentration to monitor.

The audit must also incorporate deferred liabilities: potential tax reassessments, guaranteed debts, unconstituted pension capital, and prospective IFI charges.

Selecting the right tax wrappers is the most structurally important decision, separate from asset allocation itself.

The flat tax (PFU) of 30% applies by default to capital income — dividends, interest, and capital gains on securities — since the 2018 Finance Act. Opting for the progressive income tax scale may be preferable if your marginal rate is below 30%, or if you have capital losses to carry forward.

France's impôt sur la fortune immobilière (IFI) applies once the net value of your taxable real estate assets exceeds €1.3 million on 1 January of the tax year (CGI article 964). It applies only to real estate — not to PEA holdings, life insurance units of account invested in equities, the PER, or securities portfolios.

Three legally sound levers reduce the IFI base:

1. Mortgage debt: borrowings used to acquire or construct taxable assets are deductible from the IFI base.
2. Dismemberment: bare ownership (nue-propriété) is not taxable in the IFI of the bare owner. Transferring bare ownership to your children while retaining the usufruct (usufruit) removes the transferred share from your IFI base while preserving your rental income.
3. Shares in operating companies: assets used principally in a commercial, industrial, or professional activity are exempt from IFI, subject to conditions.

Our reading: IFI is not the sole reason to sell or retain a real estate asset. But it must be factored into the overall analysis as soon as taxable real estate net worth approaches the threshold. A director who reaches €1.3 million in taxable real estate without having planned for it faces a double constraint: an annual tax charge and disposal costs if they want to exit.

The trade-off between direct real estate, SCPI funds, and financial assets arises regularly in files involving directors aged 45–55 who have built a first layer of wealth and are looking to rebalance it.

Direct real estate brings control, bank leverage, and a certain discipline of forced saving. In return: management responsibilities, vacancy risk, concentration risk, and heavy taxation on rental income (progressive income tax scale plus 17.2% social charges).

SCPI: simplifies management, spreads geographic and sector risk, and allows progressive entry. The drawback: SCPI income is treated as rental income (same taxation as direct real estate), liquidity is limited, and entry fees remain high (8–12% depending on the product — to be checked against current product terms).

PEA: for listed assets, this is the most tax-efficient wrapper after five years. It supports genuine geographic and sector diversification with near-immediate liquidity.

The right trade-off depends on your marginal tax rate, your IFI base, your liquidity needs, and the share already locked into real estate. There is no universal answer.

Consider a salaried managing director of a SASU (société par actions simplifiée unipersonnelle), aged 50, whose wealth breaks down as follows:

• Primary residence: €550,000 (net value)
• Buy-to-let portfolio (3 units): €480,000
• Multi-support life insurance: €180,000
• Securities account: €90,000
• Cash: €70,000
• SASU shares (estimated market value): €130,000

Analysis:

1. IFI position: the primary residence benefits from a 30% reduction (i.e. €165,000 deducted). The buy-to-let portfolio is fully taxable. Estimated IFI base: (€550,000 × 70%) + €480,000 = €865,000 — below the €1.3 million threshold, but the margin is narrow if values rise.
2. Real estate concentration: 68% of net worth is in property. In the event of a market shock or urgent liquidity need, options are limited.
3. Rental income taxation: at a 41% marginal income tax rate, rental income is taxed at 58.2% (41% + 17.2% social charges). A corporate-rate SCI (IS election) for future acquisitions would allow depreciation and income deferral.
4. PER under-utilised: no retirement plan contributions in place. An annual PER contribution of €20,000 would reduce income tax by approximately €8,200 (at the 41% marginal rate), while building retirement capital.
5. No estate planning in place: no dismemberment structure, no donation. Gradual transfers of bare ownership on the rental portfolio could materially reduce the future taxable estate.

Suggested rebalancing direction: reduce direct real estate exposure to 55–60% over five years, fund the PER consistently, build the PEA, and initiate a first dismemberment operation on the rental portfolio.

A patrimonial holding company is often presented as a universal solution. It is not. It becomes relevant when several conditions are met:

• You receive regular dividends from your operating company and wish to reinvest them without immediate personal taxation.
• Your investment horizon is long (at least 8–10 years) and you can absorb the structure costs.
• You have a planned acquisition of assets — real estate, fund stakes, SCPI units — that the holding company can hold at the corporate tax rate rather than at your personal income tax rate.

The holding company defers personal taxation, allows dividends to compound at the reduced IS rate (15% up to €42,500 in profit, then the standard rate), and provides a more flexible framework for future asset transfers. But it adds complexity: two sets of accounts and tax returns, regulated conventions to document, and governance to formalise.

The under-estimated risk: a poorly structured holding company can become a patrimonial black box — heterogeneous assets, high running costs, difficulty extracting assets without fiscal friction. It does not replace a coherent wealth strategy: it amplifies one, in both directions.

Démembrement de propriété (property dismemberment) is one of the most powerful tools for preparing estate transmission while retaining the income or use of an asset. The value of the bare ownership transferred is calculated using the fiscal scale under article 669 of the CGI, determined by the usufructuary's age at the time of the donation — which significantly reduces the taxable base for gift tax purposes.

For a deeper analysis of these mechanisms, see our dedicated articles:

• Démembrement de propriété : principes et usages
• Nue-propriété et usufruit : optimiser l'immobilier
• Barème du démembrement

For organised family transfers, a donation-partage locks in values at the date of the deed and avoids later disputes between heirs. The donation au dernier vivant is a separate mechanism worth examining to protect the surviving spouse.

In practice: a well-structured dismemberment at age 55 can transfer 40% of a property's value without gift tax, compared with only 20–25% at age 70. Anticipation has a quantifiable value.

Before each tax year-end, check these points:

• Is the PEA ceiling (€150,000) being fully utilised?
• Are PER contributions calibrated against your projected marginal tax rate?
• Is your IFI base approaching or exceeding the €1.3 million threshold?
• Is your life insurance beneficiary clause up to date?
• Has a donation been considered if you have adult children?
• Are professional and personal assets clearly separated?
• Is rental income taxed at the income tax rate or through a corporate structure — is that still the right choice?
• Do you have a dashboard that aggregates all your assets into a single view?

In 2026, three trade-offs come up systematically in the files we advise on:

PER versus immediate dividends: for a director at a 41% marginal income tax rate, contributing to a PER rather than distributing dividends taxed at the 30% PFU generates a significant and immediate tax advantage. The trade-off is capital lock-in. The right choice depends on short-term liquidity needs and matrimonial situation.

SCI at corporate tax rate versus direct ownership: for rental portfolios that do not require immediate income distribution, a corporate-rate SCI allows depreciation and capitalisation at the IS rate. It becomes less advantageous when dividends must be drawn regularly, as the double taxation effect erodes the benefit.

Early dismemberment versus waiting: every year without an estate planning structure in place has a measurable fiscal cost. We recommend initiating a first dismemberment or donation operation once the situation is stable — without waiting for a triggering event.
