Hello! I'm a 13 years indie games developer and I'd like to sell my game
I don't need to have a company...?
If you're going to sell your game, you're going to earn money. If you earn money, taxes must be paid
to the government(s) where you live. You don't have to form a company, but a minor can't enter into
legal agreements, and may not be able to pay taxes.
Legal agreements must be entered into in order to sell your game on Steam. You'll need an adult
(parent or guardian) to perform those legal agreements for you.
And your income may have to be added to your parent's taxable income for tax purposes (this I'm not
certain about, and it likely depends on the tax laws in your country and region and city).
