Sorry, you have no idea what you are talking about.

1) Here are the corporate taxes https://en.wikipedia.org/wiki/Corporation_tax_in_France

2) The 75% is not a "revenue" tax. You don't even know what revenue is.

>The tax introduced by Francois Hollande as the 75% tax is in fact an additional employer contribution of 50% which when existing social security charges are added reaches 75%. The proposed tax was subsequently modified after being rejected by the Council of State[7] and was implemented in 2014 in its current form and will be discontinued as of January 2015

The discontinued 75% "tax" also included pension and health insurance.

If this not existing tax is not what you were referring to, what is this "revenue tax" you are talking about.

Here is an overview of european taxes https://en.wikipedia.org/wiki/Tax_rates_in_Europe

To be honest I left france several years ago and I was not aware about that tax was transformed to "only" 50% of tax instead of 75%. Anyways that doesn't change the fact that france is still a fiscal hell and that most rich peoples left the country already after this stupid tax was voted. The same year I left there was also thousands of other people's who left france. I heard the peak was in 2015 with more than 10k millionaires who left france that year alone. Stupid taxes and fiscal instability are 2 majors reasons why france is slowly dying.
