Two company forms, two social regimes, two cost logics

Inès is choosing between a single-shareholder simplified company and a limited company with majority-owner management. Same activity, same projected profit of 60 000 €, yet two social regimes with different rates, different protection and different payment timetables. The company form settles the question before it is even asked: the arbitrage is not the same one depending on which regime applies.

Employee-treated: the general regime's protection

The company form is not chosen for governance or investor entry alone. It mechanically determines the director's social regime, and therefore the cost of every euro they draw for the whole life of the business.

The president of a simplified joint-stock company belongs to the general social security regime without being an employee in labour-law terms. They contribute like a senior manager, earn the same health and pension rights, and remain outside unemployment insurance.

Contributions are high and fall as payments are made, with a monthly payslip. Paying no remuneration means owing no contributions, but it also means acquiring no rights for the period concerned.

That status carries one plain virtue: the social charge tracks activity exactly. A year with no payment costs nothing in contributions, which shelters a young company whose result stays uncertain from one year to the next.

Self-employed: cheaper, less covered

A majority-owner manager of a limited company falls under the self-employed regime. Contributions, computed on net remuneration, run appreciably below those of an employee-treated director for the same income, with narrower cover.

The cost gap is real, but it is paid in entitlements: stricter access to daily sickness benefits, a less generous supplementary pension, and an income protection need that many directors discover only when they need it. The cheaper regime leaves the director to arrange that protection privately, at their own cost.

That deferred reconciliation is the main cash trap of the status. A strong year produces a demand the following year, often just as activity slows: setting the money aside is basic hygiene rather than caution.

• Health cover: broadly comparable across both regimes for routine care.
• Daily sickness benefits: stricter eligibility for the self-employed, but a higher daily cap (65,84 € against 42,97 € for the employee-equivalent director).
• Basic and supplementary pension: faster accrual for the employee-treated director.
• Unemployment insurance: absent in both cases, unless private cover is bought.
• Income protection and disability: private cover needed, especially for the self-employed.

None of those lines shows up in a gross cost comparison. They are exactly where the difference is felt during a long absence from work, and a purely tax-driven calculation says nothing about them. The two regimes are therefore a trade, not a ranking.

The remedy is a monthly provision set aside from the first euro collected. It turns an unexpected demand into an anticipated cost, and removes the leading cause of cash strain in young majority-managed companies.

What the form changes in the arbitrage

For an employee-treated director, dividends escape social contributions and bear only the levies on investment income. The arbitrage there is purely financial, between high social charges and the taxation of a distribution.

For a majority-owner manager, the share of dividends above a threshold linked to share capital is brought back into the contribution base. Distribution then stops being a way round, and the arbitrage changes nature entirely.

The calculator linked here models the employee-treated case and uses average contribution rates that can be edited. A majority-owner manager must substitute their own rates before drawing any conclusion from it. Its result is a starting point, not a verdict.

The form is chosen at incorporation and changes awkwardly afterwards: converting a limited company into a joint-stock one requires a collective decision, sometimes an appointed auditor, and carries tax consequences worth pricing beforehand. Decide it with a five-year view: the cheaper regime on day one is often the costlier one later.
