(Death) and Taxes!

[Sarnia]

I wonder if someone could possibly answer me a quick question.  We seem to be unable to get a "straight" answer from anyone!

Hypothetical income of £30k p/a

What sort of taxes would be taken out of this i.e. social security/income tax/health tax etc.

A "friend" suggested that upwards of 75% of any income would go straight to the State - and I cannot help wondering how other people manage to live in France if that is that case?

 

Thanks for any advice!
