Does a US LLC owned by a non-resident alien have to pay US taxes if it operates exclusively online?
As you said, in the US LLC is (usually, unless you elect otherwise) not a separate tax entity. As such, the question "Does a US LLC owned by a non-resident alien have to pay US taxes" has no meaning. A US LLC, regardless of who owns it, doesn't pay US income taxes. States are different. Some States do tax LLCs (for example, California), so if you intend to operate in such a State - you need to verify that the extra tax the LLC would pay on top of your personal tax is worth it for you. As I mentioned in the comment, you need to check your decision making very carefully. LLC you create in the US may or may not be recognized as a separate legal/tax entity in your home country. So while you neither gain nor lose anything in the US (since the LLC is transparent tax wise), you may get hit by extra taxes at home if they see the LLC as a non-transparent corporate entity. Also, keep in mind that the liability protection by the LLC usually doesn't cover your own misdeeds. So if you sell products of your own work, the LLC may end up being completely worthless and will only add complexity to your business. I suggest you check all these with a reputable attorney. Not one whose business is to set up LLCs, these are going to tell you anything you want to hear as long as you hire them to do their thing. Talk to one who will not benefit from your decision either way and can provide an unbiased advice.
