PUMA Tax France 2026: Calculation, Thresholds and Reduction Strategies

France's PUMA tax — formally the Cotisation Subsidiaire Maladie (CSM, subsidiary health contribution) — is among the most frequently overlooked social charges in French tax planning for company directors and investors. Introduced under the Protection Universelle Maladie (PUMa) reform in 2016, it applies to individuals who benefit from French health insurance coverage without contributing sufficiently through professional income. The result: a targeted levy on passive and investment income when earned by those who draw little or no salary.

In 2026, the calculation parameters are anchored to the revalued PASS (Plafond Annuel de la Sécurité Sociale, annual social security ceiling), set at €48,060. The maximum CSM liability reaches €3,123.90 per year. For SASU directors, property investors with SCI structures, and expatriates returning to France, understanding this mechanism is a prerequisite for sound remuneration planning.

Short answer: The PUMA tax (CSM) is levied at 6.5% on the portion of investment and passive income (dividends, rental income, capital gains) that exceeds professional income, capped at the PASS (€48,060 in 2026). It falls to zero automatically when professional income reaches 50% of the PASS (€24,030).

The CSM is a social contribution, not a tax. Its legal basis is Article L. 380-2 of the French Social Security Code (Code de la sécurité sociale), as clarified by Decree no. 2019-349 of 23 April 2019. It is collected by URSSAF, France's social security collection body, and finances the universal health insurance coverage extended to all French residents regardless of employment status.

The logic is straightforward: anyone residing stably in France is covered for healthcare. Those who generate sufficient professional income already contribute through payroll or self-employment contributions. Those who do not — but who receive significant investment income — are asked to contribute via the CSM.

Three profiles account for the vast majority of CSM liabilities seen in practice:

SASU company directors who pay themselves a minimal or zero salary while extracting value through dividends. A SASU director on €3,000 gross annual salary receiving €40,000 in dividends is a textbook CSM case.

Property investors and SCI shareholders whose rental income (revenus fonciers) is significant but who lack substantial professional income to offset it. An SCI managed on an IR (income tax transparency) basis generates rental income that feeds directly into the CSM base.

Returning expatriates who re-establish French residency and receive investment income — dividends, foreign pensions, rental proceeds — before resuming a professional activity. The date of stable residency for CSM purposes does not always align with the date of return for income tax purposes, which creates exposure in transition years.

The formula is:

CSM = 6.5% × (Investment income − Professional income)

The result is capped at 6.5% of the PASS.

Worked example — SASU director:

A SASU president pays himself an annual net salary of €3,000. He also receives €40,000 in dividends and €8,000 in net rental income in 2025.

• Investment income: €40,000 + €8,000 = €48,000
• Professional income: €3,000
• CSM base: €48,000 − €3,000 = €45,000
• CSM due: 6.5% × €45,000 = €2,925

This CSM of €2,925 is charged in addition to the PFU (flat tax on capital income), the prélèvement forfaitaire unique (PFU), which in 2026 stands at 31.4% (12.8% income tax + 18.6% social levies, after the 1.4-point CSG increase effective 1 January 2026). The CSM is a separate levy on top of the PFU; total charges on dividends can therefore exceed 31.4% significantly for low-salary directors.

Alternative scenario — salary raised to €25,000:

• Professional income: €25,000 → exceeds 50% of PASS (€24,030)
• CSM = €0: automatic full exemption

This single threshold is the pivot point for remuneration vs. dividend arbitrage decisions in French holding and operating structures.

One common error: assuming the PFU covers the CSM. It does not. The PFU (flat tax) — 31.4% in 2026, i.e. 12.8% income tax plus 18.6% social levies — applies to dividends and capital gains at the income tax level; the CSM is a separate social contribution administered by URSSAF. See our note on the 2026 flat tax framework for a full breakdown of the layering.

Exemption is automatic — no application required — in the following situations:

• Professional income at or above 50% of the PASS (€24,030 in 2026).
• Recipients of the AAH (disability allowance) or ASPA (solidarity allowance for the elderly).
• Students under 28 enrolled in an accredited institution.
• Cross-border workers covered by another EU member state's social security regime.
• Individuals affiliated with another mandatory French insurance scheme (agricultural regime MSA, energy sector IEG, etc.).
• Non-residents: the CSM applies only to individuals with stable, regular residence in France.

For returning expatriates, the transition period is particularly sensitive. French residence for CSM purposes may be established before the individual has resumed professional activity, creating a window of exposure that can last one to two years.

1. Exceed the 50% PASS threshold — set annual gross salary at or above €24,030 (approximately €2,000 gross per month). This is the cleanest, most reliable solution. The additional payroll contributions must be modelled against the CSM saving, but for most SASU structures the break-even is reached quickly. Our analysis of SASU social charges provides the underlying numbers.

2. Rebalance the salary/dividend mix incrementally — if the €24,030 threshold is not immediately achievable due to cash-flow constraints, every additional euro of salary reduces the CSM base by one euro. A partial increase from €3,000 to €15,000 salary cuts the CSM base by €12,000 and saves €780 in CSM.

3. Analyse the holding structure — in some configurations, interposing a holding company modifies the nature or timing of income flows. This is technically complex and depends on whether dividends are genuinely distributed to you personally or retained at holding level. Engage your specialist in French holding tax structures before implementing.

4. Time dividend distributions strategically — in years when professional income is higher (due to a consultancy contract, sale of a business asset, or performance bonus), distributions generate a lower CSM base. In years when professional income is low, defer distributions where possible.

5. Redirect savings toward CSM-exempt instruments — Livret A, LEP, and LDDS interest is excluded from the CSM base. The contribution ceilings are modest, but every euro channelled there reduces taxable investment income. For wealth management strategy as a company director, this is part of a broader asset allocation review.

The CSM operates on a one-year lag:

• Income earned in year N is reported to the tax authority (DGFiP) via the annual income declaration in spring N+1.
• The DGFiP forwards the relevant data to URSSAF.
• URSSAF issues the CSM demand in Q2 of year N+1 (spring/summer).
• Payment is due within 30 days of notification.

For 2025 income, the CSM demand will arrive in spring/summer 2026. Directors who distributed large dividends in 2025 without provisioning the CSM face an unplanned cash call at an inconvenient moment. Provisioning the estimated CSM at year-end, alongside the year-end accounts, is standard practice.

Directors and investors unfamiliar with the CSM mechanism regularly make the following errors:

Failing to provision the CSM at year-end. The demand arrives six to nine months after the year closes. By then, cash may have been distributed or reinvested.

Assuming the PFU is all-inclusive. The 31.4% flat tax on dividends in 2026 does not cover the CSM. These are two distinct levies collected by two different bodies (DGFiP and URSSAF).

Including exempt income in the declared base. Capital gains on a primary residence are excluded. Including them inflates the declared base and the resulting liability.

Overlooking rental income from SCI structures. Net rental income flowing through an SCI held at IR level feeds directly into the personal CSM base, even without a formal dividend distribution.

Missing the two-month contestation window. If the URSSAF assessment contains errors — wrong income year, misclassified income, or failure to apply an exemption — the challenge must be filed within two months. Late challenges are inadmissible.

If you believe the URSSAF calculation is incorrect or that an exemption applies:

• File within two months of receiving the demand.
• Submit a written challenge to the Commission de Recours Amiable (CRA) at your regional URSSAF, with supporting documentation (income tax returns, proof of affiliation to another regime, proof of professional income).
• If the CRA rejects the challenge or does not respond within the statutory period, appeal to the Tribunal Judiciaire (social division).
• If the error originates from the data transmitted by the DGFiP, simultaneously submit a correction request to your local tax office.
