Hello all, I'm just joining this discussion as I've been researching how to register for IOSS as well. I understand that IOSS registration is not mandatory until you reach a distance selling threshold of £8800 of goods sold to ALL EU countries combined. I will register in any case as I don't want my customers to bear the burden of paying VAT and customs handling/ admin charges on receipt (those charges are obscene and seem completely arbitrary). So I'd rather charge the EU VAT rate through my online shop and remit to EU - otherwise I expect to lose all my EU business. Regarding zero-rated VAT for exports - that's just the government trying to trick you! All it means is you pay no VAT for your goods to *leave* the UK. It has no bearing on what VAT is charged in the receiving country. It's that simple, but the language used makes you think you're sending for free!! Also I believe there is a clear reason why we are not able to register for IOSS right now, and that's because EU countries (and probably UK too) are simply not prepared to implement it. I expect the changes due on 1st July will be postponed until 2022. See this article which explains my reasoning (Sorry, as a new user I can't post the link): on the Avalara website article headline "Germany to miss postal operators IOSS July 2021 launch" So we languish for longer in limbo... Thanks for having this discussion as it's the only place I've encountered such diligent people actually trying to move forward with IOSS - likely because most small businesses, at least, are completely unaware of upcoming changes to the low value threshold.
