"This is all very confusing for us as well. We are speaking with professionals to make sure that we fully understand VATMOSS rules and we will build out a process that makes it easy for creators and patrons as well!"
Basically "we don't know lol"
I wrote to vatlive.com too, and according to them - since we (creators) on Patreon are only taking donations and WE don't charge for the service, nor we provide a service - VAT MOSS doesn't apply to us.
The third new piece of info is this pdf chart I came across: www.gov.uk/government/uploads/…
Again, we are not providing service of any sort, the new rules don't apply to us.
So, based on these my initial panic is more or less gone now, and I'm quite (if still not 100%) sure that I can continue things the way they were before. Tough I'd like my patrons to send their e-mail addresses to me, so I can further eliminate the 'automatic' and 'service' parts of the whole process. I'd like to e-mail their drawings directly to them.
