Ack, I started selling games for the first time a month ago and I have 0 idea what I'm supposed to do about the taxes at the moment, hahah. . . e.g. I'm selling soundtracks via Bandcamp, and according to the polices, we are supposed to handle all the taxes including VAT ourselves. Apparently different places have different rates too; do I just use the US's rate since Bandcamp's there? And are there any other vendor taxes to worry about? Many thanks in advance!
