Hi. I am owner of a browser based game Hero Town. I receive payments via Paypal. Users purchase credits and V.I.Ps via Paypal. Currently it does not earn more than £100 a week but I believe that it will start earning me more than that. Since I am getting payments via Paypal and my Paypal account is premiere so it deducts a percentage from anything I get. Do I need to pay tax when I earn via Paypal? What paper work do I need to do so I could have everything in legit way? Thanks in advance.
