I was wondering under what situation might I owe tax in Argentina? If I live less than 6 months at a time do I owe taxes? What if during this time I do something that might be classified as working, for example, if I work on writing a book, and later, months or years later, make money from the book. What if instead of a book I write articles, or do some other online work where I get paid sooner. And finally, what if I get the 3 month extension to the 6 month stay? To be clear, I'm not looking for what I can get away with, but what is the law if I'm totally transparent with the authorities about my activities. As a USA citizen I'm concerned about double taxation, because I heard that wherever I go I have to file for USA taxes, even if I don't reside in USA, unlike most other countries where taxation seems to be residency based. I imagine I have to double check everything with a tax expert, but wanted to get a general sense of what I might expect. Thanks.
