Scratch that is an interesting way to look at it...would be great if some of your questions were answered.
About this contract - is working for TSR as an FA or SA an actual job? Do they pay taxes? If they don't then its part of the informal sector of work and is illegal.
It is and isn't "legal" if for any reason they were caught they could claim to be an independent contractor or Self Employed (if they are here in the US) and claim that they made less than $600.00 per year. This would mean though that they would have to have some sort of print out to prove the dollar amount was $600.00 or less OR Thomass gives them a 1099-Misc. showing the same with the box checked for $600.00 or less.
The tax thing to me is a sticky situation though. When we were thinking about investing in a business in another country we had to look at the tax laws for money earned in another country. For some countries, you actually get a tax break for your investment and the money earned is not taxes as high because you are considered "helping" the country to develop. Sweden was not on the "under developed" country list though. It was mostly Eastern European, former Soviet Block countries for Europe.
It would, for those in the US, boil down to how much an FA/SA actually makes in a year. A good rule of thumb though to be on the safe side, for those FAs/SAs in the US to keep in mind is that any money earned is taxable/reportable if you are over a certain age (whether it be a "legal" job or not). Now whether they claim it as "self employed" or "Independent contractor" is up to them, but they should be claiming one or the other. You still have to "claim" it, it is just if it is $600.00 or less it is not "taxable income."
As far as a resume, I doubt any employer would look at the time they were "self employed" or an Independent contractor" for TSR in very high regard. On that point you are spot on.
