I am looking to compare how much tax I would pay if I moved from Montreal to Madrid. For simplicity, assume a canadian salary of $100k - this converts to taxes around 36% in Montreal for federal and provincial taxes (not including local govt taxes such as school tax etc.). What is the Madrid equivalent?

Of course the next question is...how much do you need to earn in Madrid to have a similar standard of living (again, assuming you earn $100k in Canada).
