I am 100% sure long term residents also pay health insurance. Are you an EU citizen?
Perhaps it's indeed different for EU citizens, I'm not sure. I should probably mention it there.
Actually, I _did_ pay some health insurance, but it had nothing to do with the business and it wasn't 8% or anything like that. It's like the same kind of health insurance that even tourists have to get.
I was buying just some bare minimum required insurance, and it was very low, less than 200 BGN per year.
Also, does Bulgaria support interim dividends? The loan set-up, while not an issue, can perhaps be avoided by use of interim dividends.
