There is "zákon 235/2004 Sb. § 92" which defines investment gold and frees the investment gold from value added tax when sold in Czech republic, from EU to Czech republic and when iimporting from other states. There are no restrictions.
Such conditions should be equal in whole European Union, as far as I know.
Actually that's not absolutely correct. Gold is free from VAT in Czech, but for that reason there're many additional restrictions in trading and only registered companies are allowed to trade gold. I think this is the core of a problem, because I think this is a Czech speciality and these laws doesn't apply to whole EU. And Coinabul expected that we here in Bananastan have reasonable laws, which was huge mistake.
