Firstly, thanks for the response.
The reasons I specifically asked about the US is because Itch.io is a US company and I'm not from the US. I'm actually from the UK. When it comes to doing taxes over here I'm pretty confident however when it comes to the US I have no clue. I have a feeling that I might have to file a 1040NR tax return, however it all depends on whether or not selling on Itch.io, for US tax purposes, is classed as "being engaged with a trade or business".
From what I can gather from your reply, selling things on Itch is classed as "being engaged with a trade or business" for US tax purposes?
Thanks. :)
