France’s 2026 Finance Act: analysis and implications for your wealth
Analysis and Impacts on Your Wealth
In an economic and political environment marked by uncertainty, the 2026 Finance Act and the Social Security Financing Act introduce a series of tax developments that particularly concern private clients. Understanding these adjustments, assessing their implications, and adapting one’s wealth strategy becomes essential to preserve, secure, and transfer one’s capital under the best legal and tax conditions.
Faced with increasingly complex tax regulations, support from a specialized team is crucial. A technical reading of the measures is only a first step; the challenge is to integrate them into a comprehensive wealth strategy tailored to the personal, professional, and family situation of each client.
Each tax development deserves a personalized analysis.
Our mission is to help you make the right decisions at the right time.

Understanding the Issues of the Finance Act and the Social Security Financing Act
The 2026 Finance Act takes place in a shifting tax environment. Although no major reforms have been announced—apart from the creation of a tax on wealth‑management holding companies—the text contains numerous technical adjustments that may significantly affect wealth structuring and income taxation.
These measures appear in the context of a delicate budgetary balance, where tax stability is a crucial factor for investor confidence.
This law stands out for:
the refocusing of existing tax schemes,
the introduction of new targeted taxation rules,
technical measures that can be complex to understand,
an indirect but real impact on investment and wealth‑transfer strategies.
Key Points to Remember for Private Clients
Below are the main measures that may affect private clients:
Adjustments to the Dutreil Pact
Expected refocusing of the scheme, without undermining its central role in family‑business transfers.
Revision of the income tax scale and extension of the High‑Income Differential Contribution (CDHR)
A mechanical adjustment that may nonetheless influence the overall taxation of high‑income households.
Increase in the CSG rate on certain investment income
A notable rise of 1.4 points, directly affecting the net return of certain financial incomes.
Specific tax on certain “luxury” assets held through holding companies
A new tax targeting “luxury” assets not used for operational activity within wealth‑management structures.
Changes to the private landlord status
A new tax approach aimed at encouraging affordable rental investment, including a tax depreciation mechanism.
Adjustments to PER schemes
Limitation of certain benefits after a given age, along with rebalanced taxation upon exit.
Clarifications on the new tax regime for management packages
Expected clarifications on taxation deferrals, share ownership through a PEA, provisions affecting non‑residents, etc.
A change in the BSPCE regime
Changes to the contribution‑for‑deferment regime
Tightening of eligibility requirements, including a refocusing of eligible reinvestment activities.
