I'm a sole proprietorship whose income is 100% derived from iPhone app sales and ad revenue (AdMob, and a few other ad networks). I'm currently paying substantial state taxes (6 figures anually), so I'd like to relocate as soon as possible. In particular, I'd like to move to one of the following: {Florida, Nevada, New Hampshire, Texas, Washington}, so if any of you guys who live or have lived in one of these states could let me know what taxes I need to be aware of, that would be really helpful. For example, I've read something about a "B&O" tax for Washington. If this tax is required for app sales/online ad revenue, Washington is a no-go. Thank you for the help!
Drop me a line. I can help you with this. We have just gone through the process with a company of ours.
