How to Optimise Your Wealth in 2026: A Structured Method for Business Owners

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

The most common mistake we see in client files is buying a product before understanding the situation. A life insurance policy is opened because an adviser suggested it. A buy-to-let flat is acquired because it feels tangible. A PER (plan d'épargne retraite) is subscribed to reduce the current year's tax bill without considering what it means at retirement. The result is a layered rather than constructed wealth portfolio — hard to read, expensive 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 set up, but it holds over time.

Direct answer: to optimise your wealth in France in 2026, start with a complete wealth audit, define your objectives by time horizon (liquidity, income, growth, estate planning), then select the right tax wrappers — PEA, PER, life insurance (assurance-vie), dismemberment, or holding company — and finally allocate between direct real estate, SCPI funds and financial assets, factoring in your full tax position including IFI, the 30% flat tax (PFU) and inheritance costs.

A proper wealth audit does three things a simple asset list does not:

It maps sector concentration. A business owner in construction with 80% of net worth tied to the company and a buy-to-let flat is poorly diversified, even if the balance sheet looks healthy. Professional assets (company shares, business premises, trade receivables) and personal assets must be read together.

It surfaces the real tax cost of exit. Gross asset value tells you little without the fiscal cost of disposal, inheritance or policy redemption. A property worth €600,000 may cost €150,000 in capital gains tax and agency fees to sell. That changes the net figure materially.

It identifies deferred liabilities. Outstanding tax reassessments, guaranteed debt, unconstituted pension capital, and potential IFI charges are all liabilities that belong on the audit before any allocation decision is made.

Wealth optimisation is not a single-objective problem. Most directors have three overlapping horizons:

• Short term (0–3 years): liquidity reserve, credit capacity, professional contingency buffer.
• Medium term (3–15 years): complementary income, retirement capital build-up, real estate arbitrage.
• Long term (15+ years): estate transmission, intergenerational transfers, protection of the surviving spouse.

The allocation across tax wrappers and asset classes should reflect all three, not just the one that feels most pressing today.

France offers a well-developed range of fiscal envelopes. Each serves a distinct purpose.

The flat tax (prélèvement forfaitaire unique, PFU) of 30% applies by default to capital income: dividends, interest, and capital gains on securities. Opting for the progressive income tax scale can be more efficient if your marginal rate is below 30% or if you carry forward capital losses.

France's impôt sur la fortune immobilière (IFI) applies once net taxable real estate assets exceed €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, or PER capital.

Three legally sound approaches reduce the IFI base:

1. Mortgage debt deducted from taxable property values, provided it is directly linked to acquisition or construction of taxable assets.
2. Dismemberment: bare ownership (nue-propriété) is not taxable in the IFI of the bare owner. Transferring bare ownership to adult children while retaining the usufruct removes the transferred share from your IFI base while preserving your rental income.
3. Shares in operating companies: assets used in a commercial, industrial, or professional activity are excluded from IFI, subject to conditions.

A director approaching the €1.3 million threshold on real estate alone should factor IFI into every acquisition decision, not as an afterthought at year-end.

Consider a managing director of a SASU structure, age 50:

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

Key observations:

1. IFI position: primary residence benefits from a 30% reduction, giving a taxable value of €385,000. Combined with €480,000 for the rental portfolio, taxable real estate is €865,000 — below the €1.3 million threshold, but the margin is thin if values rise.
2. Real estate concentration: 68% of net worth is in property. Liquidity is constrained; any urgent capital need forces a sale at uncertain timing.
3. Rental income taxation: at a marginal income tax rate of 41%, 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 savings plan contributions. An annual PER contribution of €20,000 would reduce current-year income tax by approximately €8,200 (at 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 holding company adds value when three conditions align: you receive regular dividends from an operating company and want to reinvest them without immediate personal taxation; your investment horizon is long (at least 8–10 years); and you have specific assets — real estate, fund stakes, SCPI units — that the holding can hold at corporate tax rates.

The holding defers personal taxation, allows dividends to compound at the reduced IS rate (15% up to €42,500 in profit), and provides a more flexible framework for future asset transfers.

The risks are real: two sets of accounts and tax filings, regulated conventions to document, and a structure that amplifies both the good and the bad of the underlying strategy. A holding company is not a substitute for a coherent wealth plan — it is an amplifier of one.

Dismemberment (démembrement de propriété) is one of the most efficient tools in French estate planning. The fiscal scale under article 669 of the CGI determines the value of bare ownership based on the usufructuary's age at the time of the donation. A donation of bare ownership at age 55 transfers a significantly larger share of the property's value at a lower gift tax cost than the same operation at age 70.

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

Before each tax year-end, review 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 €1.3 million?
• Is your life insurance beneficiary clause up to date?
• Have you considered a donation if you have adult children?
• Are professional and personal assets clearly separated?
• Is rental income taxed at income tax rate or through a corporate structure — is the current choice still appropriate?
• Do you have a consolidated dashboard showing all assets in a single view?

PER contributions versus immediate dividends. For a director at a 41% marginal income tax rate, contributing to a PER generates a material and immediate tax saving compared to distributing dividends taxed at the 30% flat rate. The trade-off is capital lock-in. The right answer depends on liquidity needs and family situation.

SCI at corporate tax versus direct ownership. For rental portfolios where income is not immediately needed, the IS election allows depreciation and income deferral at the corporate rate. It becomes less attractive if dividends must be drawn regularly, as the double taxation effect erodes the advantage.

Early dismemberment versus waiting. Each year without estate planning has a quantifiable fiscal cost. We recommend initiating a first dismemberment or donation once the situation is stable — without waiting for a triggering event such as illness or sale of the business.
