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.
