This is a good question. I also want to know if there's a way to dissable VAT for the Collected by itch.io mode? I'm in the UK and I'm not VAT registered; I'm not required to be (because I'm nowhere near the income threshold), so I don't have to charge VAT when I sell something.
^ Or, is VAT required because the sale is from itch.io, so they are VAT registered and required to charge VAT?
When I start earning £83,000+ a year, then I'll happily register for VAT as required, but I don't want to.
