It doesn't cost anything to create a simple limited company in Norway but you do have to declare the initial capital and say which bank account holds it and submit annual accounts with quarterly estimates. But that can be as little as 30 kNOK, about 3 kUSD. You can also register as a sole trader which has neither of those requirements but you are then personally liable for any debts.
