I'm going to integrate with stripe to build an alternative to itch.io for multiplayer games, it seems "digital services" are VAT free in the entire world. Edit; I was wrong, nothing is VAT free, but my government offers a "automatic" help tool to pay all the tax offices around the world: https://www.skatteverket.se/foretagochorganisationer/moms/deklareramoms/mossredovisningavmomspadigitalatjanster/tekniskbeskrivningminionestopshop.4.1c68351d170ce5545273f83.html (in Swedish but you can see the file format)
Adding to this: Indonesia, Mexico, Chile och Colombia added VAT this summer!
Still itch.io needs to fix the tax interview, otherwise nobody can use this service.
