Approximated historic exchange rates: SEK / euro-dollar-franc: ca 0.1 - 0.12
Gross salary income at 90th percentile: 567 600
Actual sales cost for a small-medium company: 1 084 050
Included: VAT ca 25%, social fees ca 31%, other misc ca 10%
Net income after taxes: 420 492
So, about 61% is lost in taxes from gross billing to net income after tax, for someone earning at 90th percentile. "The world's highest taxes" is misleading. It really depends on your family situation and lifestyle:
For those 61% you get quite a lot when the system works. Free health care, education, child care, work-life balance, freedom, nature, social life, etc. I do not recommend living in Sweden without a good private medical insurance. The public health care is top notch when it works, but without private insurance odds are it will not work well in your case. If you are willing to put in 10-15MSEK for a house/apartment you can choose areas with very good schools, but it will take you many years to find a decent rental below 30k/m.
Society is generally very nice, open, liberal, clean. Nature is wonderful. 6 month winter is made for working, 4 month summer is made for swimming. I generally expect to get ca 1500h efficient time on target from the people I had in Sweden, and I expect to pay around 1kSEK/h effective.
I used to hire people and place them in Sweden. I have sadly not done that for several years. Slowness of immigration, severe lack of rental housing, etc. A good gemeinde+canton in Switzerland is much faster and smoother.
