C-corps are their own ‘beings’, and they’re not disregarded. Hence, your income will get taxed twice. First, at the corporate level, and second, when you ‘get paid’, as salary, or dividends.
If you’re a solopreneur, I suggest a LLC. Taxed once, since it’s passed-through, and you won’t have to pay taxes (last time I checked, which was a couple of months ago) when you take money out.
But, you should weigh the pros and cons of both, and choose one.
Atlas is good, since they give you a bank account as well, because it’s much harder to get one in USA, without visiting.
