I bought a game for the first time (from my new account/US account) and I paid $0.50 for a $4.99 game. So I’m not sure how much to expect taxes for the steam deck, to plan savings etc.
I never paid taxes in my old account though (not US account), so excuse my ignorance. I live in Michigan though.
So your question has nothing to do with the steam deck.
You have a tax and borderline economics question.
This is a steam deck forum, you are seeking Tax knowledge. And you didnt even drill down to a specific region, because again, taxes vary WILDLY. In the USA you could be taxed 3-6 times on a transaction on varying levels of government.
