Mostly, I think this discussion is an exercise in premature optimization. If you don't have significant income, you're also not going to pay large sums in taxes, so it doesn't matter. If you do have significant revenue, you can afford to hire an accountant/corporate lawyer to work this out for you. As far as I know it's not a big deal to relocate later.

And you're probably just setting yourself up to get robbed, anyway, by some offshore crook - who'd be hard to go after once they took your money, because they likely know all about offshore shell company games and tangled layers of ownership.

Really, wait until the company has enough money that it can get dependable advice and representation.
