Ask HN: US LLC and foreign startup?

I believe others have this question too. If you are a company outside of the US, it can make sense to also create a company in the US. - easier to use Stripe and such. - can send invoices to US clients that are local (= easier) The question is this: if I create a US LLC, and I have about equal revenue/cost, how big of a tax burden will I have in the US? Additional info: the idea is that there is ColombiaCompany ("CC) and USCompany ("US"). US charges clients. US pays US-based providers. US pays CC for services. End of the year, US has close to zero profit. CC has profit, and pays taxes on that locally.
