50% effective or marginal? During discussions, only effective is useful. According to the PWC page:
https://taxsummaries.pwc.com/germany/individual/taxes-on-per...
Marginal tax rate is 42% on the first EUR after 278K. That would astonishingly high total income in Germany. There might be some remaining solidarity tax from the reunification, but I cannot see how you get to an effective tax rate of 50% on 100K income, which is considered excellent in Germany.
Can you share a worked example how effective tax rate can be above 50%?
