Do i need to pay a developer's fee of 99$ per annum if i want to list my web app on the apple web app store, or any other place for that matter (android etc.)? Can i ask user to come and pay for new features on my site through this web app? will I be breaching some archaic policy by doing that? This web app is complete on its own but user might want to have extra features which come at a price of course! Which merchant is the best for my basic needs. paypal comes to mind but is it my only option? this is my hobby. I have a separate day time job which does not involve software development. what do i need to do as far as paying taxes (if any) is concerned. am i liable to pay taxes? I do not want to create my own company etc. just because im developing this web app. By the way, if you intend to reply on tax-related questions, please understand I reside in England.
