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.
I paid about $50, but it will depend on your state. My total for the 1 TB was $700.36.
