That's the crux of the problem - billionaires. Before (and most important - IF) you become a billionaire, you will experience the highest tax rates in the world.
Sorry for︉ intervening late in the conversation. I see you are starting talking SASU, RSA, CMU...
Take it from somebody who went there - DON'T DO IT. DON'T DO BUSINESS IN FRANCE.︊ They will nail you to a pole and start taking turns on you a*s for︋ YEARS.
You will pay 70% tax, you will have to produce countless documents every month,︌ your local tax office will send you "lettres de rappel" by mistake every month, la︍ secu will take money from your corporate account first and ask questions later, you'll get︎ grey hair, and when you throw in the towel and shut down your SASU, you️ will owe them for 3 MORE YEARS.
Don't trust your Stockholm Syndrome friends who own a SASU and tell you you'll do fine - check for yourself. You WILL pay 70% tax. Also, do the simulations: no matter what form of incorporation you choose (microentrepeneur, SASU, SA, whatever) - you will end up paying 70% tax. The system is so rigged, it's ridiculous. Whatever you do (only salary, only dividends, half and half, choose another form of incorporation), you'll come up with the same numbers. Do the calculations yourself, don't ask the accountants, they are prisoners too (they are entrepreneurs) and need more customers just︀ not to drown in the bills of the Fisc.
I'll be glad to show you︁ the numbers if you like.
