You're asking about tax residency which is a hassle depending on where you are or where you're from. I am not a lawyer, just personal thoughts :) A not bad idea however, is to incorporate a small limited company that can bill your clients around the world. Clients tend to like this as it is simple to declare expenses. Don't take a $50 Cayman-ish Internet registrar; take a reputable one that will act as named company secretary, $200-$500 should be fine depending on where you are. Gives you a registered address and a professional to call if you freak out. You need to keep books and file tax reports, but is not a hassle and can save a lot of hassle. Pay yourself from that company and when incorporating it (less than 30 minutes), wherever you are, ask your accountant/company secretary how the company should pay taxes. For your case (wherever you are) they will have heard the question a thousand times before and give you frank advice; this non-charged advice saves them time during busy periods in the year. You still need to do the books and keep necessary paperwork, or send it to them. Do not do the above and work as a Nomad while receiving income from a client in the same country (unless you're incorporated in that country, or on a business visa but we're getting really case-by-case in this, ahem, case). You'll be treated as an illegal worker, opposed to a cash-injector. A bit of a ramble. How something in there was useful.
