Thanks for answering! Clarifications below:
* The C corp would pay tax on its revenue in the form of federal corporate income tax in the US (15% bracket), and no state corporate income tax (Wyoming).
* The goal would be to only pay the tax on revenue while in Ireland (since I wouldn't pay myself a salary/dividends while abroad), and then pay myself salary/dividends after I return (which would trigger the second part of the double taxation you mentioned).
* That's a good point!
* Another good point, and sage advice. I'll definitely go that route if I decide to move forward with this approach, given how complicated the arrangement could become.
