Hi, thanks for your response! Well, actually, I am in EU, so I will definitely have to deal with VAT)) But as for other countries, I asked the tax specialist on global taxes, and I was told that since it is not a digital service (where your student just streams pre-recorded videos or download a ready-made course - with that you have to be really careful especially for EU sales) and it is not physical goods, I don't have to think about sales taxes in other countries. Well, except for EU. This is a service and it doesn't physically cross the border.

I mean I am still not a 100% sure that this is all true, because that tax specialist was from EU... but she works remotely as a consultant herself for clients from various countries, so at least she knows the rules better than I do And as I understand, no one bothers with this on a regular basis

If I find out something else, I'll post here.
