You called me dim as you challenged my point that SE cannot claim unemployment in Finland and be boss of MS and used your mate being a pensioner to prove it. Oh an don't wory I didn't take offence

As I already wrote and you agree upon, the head of Nokia is an expert role. Your argument scores 10 / 10 for innovation but 0/10 for practicality! Tax authorites grant people this tax regime before they start their job. I sort of think it'd be anarchy if they can change someone's tax rate based on how well the tax authority think that they do the job!! Nice thought though and would like to be a fly on the wall when the tax inspctor told SE that he has been downgraded to a non expert!!
Also whilst I went along with your 90k, I think the income is higher in practical terms. You do not get any ability to set off anything against tax. So it is 35% + 6% (pension /unemployment) on everything. So no tax relief on mortgage interest, student or other loans, home improvements / cleaners etc + no travel to work allowances etc. Just plugged in for Kaunienen, a mortgage, child care expenses and 100k income (to make calculating the tax % easier!) - it came to 29%. I repeated at 10k / month and even thatcame about at 39% so 4k a year better off (it cost me this in flights to take my family to see their grandparents for Xmas last year)
Maybe someone else has seen a recent income distribution table, but while not unheard of, incomes over 100k and 120k (if you but my point that expats have some higher costs) are extremely rare....
