I want to be boss of a studio that I make.
What are responsibilties of a studio boss?
And how do i make it legal?
I mean I cant just say my studio name is AWESOM STUDIO and then think I own this studio I just made up..
Do I have to register it somewhere? Is there any fees?
and when is a good time to start the studio when you are making a game?
Should I make it before i recruit someone onto a team?
IIRC you were from sweden so...
Those two links should help you, for a single owner business you don't have to register your business, you must however report to skatteverket that you have a business since you will have to pay taxes.
Other businessforms you have to register with bolagsverket and in the case of aktiebolag you have to push in 50.000 SEK in own capital aswell. (aktiebolag has some pretty big tax advantages though as money payed out to shareholders are taxed far less than salary payed out to employees)
a game studio is no different from other businesses, you run it the same way and pay salaries to your employees the same way. (If you plan on not paying people you're far better off making them co-owners of the business)
