The most frequently asked questions from our clients
A SASU is a single-member SAS whose chairman is treated as an employee (social contributions ~60-65% of net salary, i.e. employer cost 1.55-1.70× net, general social security coverage). An EURL is a single-member SARL whose manager is self-employed (contributions ~45%, SSI). In a SASU, dividends are still subject to corporation tax first and then the 31.4% flat tax. In an EURL, extra social contributions can apply to dividends above the 10% capital threshold.
A holding company becomes relevant when you have several subsidiaries, want to optimise dividend flows (parent-subsidiary regime: 95% exempt), finance new investments from the holding, or plan an estate transfer. It is particularly well-suited to real estate investors with multiple SCIs.
Generally yes, once your rental income exceeds €15,000/year. The real-expenses regime allows you to deduct actual costs plus depreciation (property and furnishings), which often reduces taxable income to zero. It requires an accountant, but the tax saving is very significant.
The optimal mix depends on your goals: if you need immediate liquidity, a combination of salary and dividends is often best. If retirement savings are a priority, salary maximises pension contributions. Use our simulator to test different splits. A meeting with our team refines the analysis based on your personal tax bracket.
