Frequently asked questions
What we are being asked to do.
Are the simulators up-to-date with the 2026 rules?
Yes: social security contributions of 18.6% on capital income and 17.2% on assurance-vie, FCPI and FIP eligible in 2026, PER ceiling calculated on the annual social security ceiling. Each page indicates the applicable rule.
Is my data being recorded?
No: the calculation is done in your browser. If you request to receive a calculation by email, your address and this calculation are transmitted to us, and nothing else, in accordance with the General Data Protection Regulation (Regulation No. 2016/679).
Is a simulator enough to make a decision?
It gives a rough idea. The decision depends on your overall situation: this is the purpose of a fixed-price wealth assessment, or a 10-minute call to determine if your case warrants one.
