I did the math and it is pretty much what we are supposed to pay in italy, except that we have ways to legally trick it.

Eg. if you use the right combination of taxcode and profession, the state will require you to not pay taxes on a % of your income due to it being considered expenses, while your actual expenses are much lower, giving you a defacto taxcut. This is 100% legal, the catch is that you need to have some favorable conditions to benefit from it and close but not more than 85k yr income (the closer you get to the limit the more favorable it is).

If you don't have a way to do this in spain, things look very bad.
