Firstly, you’ll must check in with Her Majesty’s Revenue and Customs HMRC, that’s the Tax Office to let them know you are now self hired. HMRC are aware that a large number of people at the moment are working online, in online affiliate marketing, promoting on eay, etc and even use a application programme called Xenon that plays numerous searches, connecting people in combination. E. g.
in eBay Xenon will scan and find those that are making a large number of transactions; software and programs equivalent to this turns into ever more normal in the arriving years as they refine how it works and as more data is available online and electronically.
