Quote From Critchley:
Be wary regarding Netherlands. I looked into it and thought ooh that looks like a lot of money, and then you realise that on that salary you will be taxed roughly 52% (so basically cut the stipend in half). The Nordic countries consider it a job as well, but again you appear to get a large stipend but Sweden's tax rate is about 60% (I think) and the others are high as well. When they are considered a job, look at the tax rates as you may end up getting a lot less than you think you will. I believe it is treated like a job in Switzerland as well.
