it is not 40%, it depends on your civil status and your tax credits. For single person your annual salary will be taxed at 20% until €36,400 and taxed at 40% the rest. You have to pay also the Universal Social Charge.

And that's why I said "around 40%" but you're right, civil status changes it significantly

Well, effective final % as taxes/gross pay relation is more like around 30% unless you have a very high salary.

There are some online calculators that make it easier to calculate
