If you work in the US, and most of your clients will be in the US, most tax agencies (and probably IRS, but I'm not sure) will effectively presume you're a US-based company. It doesn't matter if your company is registered somewhere else, they'll presume it as a US company. The same laws apply in most European countries. Why? Because otherwise all freelancers would simply register in the country with the lowest tax to dodge their national taxes. Obviously governments don't want that. If you have the opportunity to physically relocate to another country though, then it becomes interesting to find places with lower tax rates. Countries like Singapore won't care if you're a foreigner opening a company and are never there. It's mostly about your personal tax residency what matters. An increasingly common construction with people working remotely is a Hong Kong or Singapore company, and either no personal residency anywhere (e.g. traveling around perpetually), or a personal residency in a place with lower personal tax. Think Bulgaria or Panama. If you're a US citizen, there's extra difficulties here. You'll be taxed for any income above $100K/y, even if you're not a US resident anymore. If you don't want to be taxed in the US, you'll have to forego your citizenship (!). P.S. IANAL.
