Yeah, LLCs don't appear to be the best method unless you can prove to the gov't how things were taxed (or not). That said, I'm not entirely sure things get that bad. First off, it's not a 90% rate, by those (worst case) numbers, it's a 70.08% rate. Still absolutely terrible, but... I'd take advantage of any advice you can find, both on local and US perspectives before committing to any course of action involving this product. Particularly looking forward to additional blog posts and resources on this, along with stories of best practices that are country-specific :)
