I am simplifying a bit. I would have to change from employment to invoicing my employer. That would be somewhat beneficial. The real move is to get a new contract with someone else which is very much doable and not as hard as consulting or contracting in other countries can sometimes be. Then you get paid a bit of a premium and can really use the tax benefits of controlling your personal income tax and give out dividends[0].

The things for me is if I go through the trouble I might just do it properly. But that I want to do even less. So then there are a lot more options on the table. If I'm really going to change things up maybe I change careers, location, study, travel or whatever. Which is probably a fallacy.

But I guess the point is that when I file those easy taxes and even tough I don't really dislike taxes or the Swedish tax system I don't think that is the whole story. If you have decent income, and mostly only income, and can't use those personal income tax deductions your tax rate is high enough (50-60% marginal) that it is quite beneficial to hire yourself through a company and get access to those other tax breaks. And if you do then you do complicated taxes (compared to personal taxes).
