Hi all. I'm looking to start properly selling figurines for Warhammer and other games online. I already do so on a small scale and they're selling well, but I'm looking at expanding as buyers always seem happy with them and come back often. I was wondering how taxes apply to online sales because I can't get my head around it. I've looked at sites like this [URL="https://www.income-tax.co.uk/"]tax tool[/URL] but can't find much about sales, but my income is very close to the higher tax band so I'm getting a little stressed about it.

Thanks!
