Greetings to all: I have decided to promote my services and make my income as an independent contractor (teaching a language, translations, etc), but do not know how to start. These are my questions: 1. What kind of money do I have to make before I have to start paying taxes? 2. Who (and how) is going to know that I have reached that income if I am paid through PayPal or personal checks? 3. If I do have to declare taxes, how do I do that? Do I admit to every penny I have made? When and how do I pay the taxes? 3. Do I have to establish a new bank account to link a PayPal to and deposit the checks? 4. Is there a point when I should register myself as a business (I am in the process of creating my own website)? Why? 5. Is there a comprehensive guide/book I could get to help me answer these questions? (With a two year old son constantly at my side I simply cannot stop and browse the bookshelves and read extracts...) Thank you in advance for your time and input.
