Product pages – wrong tax calculation

Hello everyone,

I got a problem with WooCommerce: For whatever reason WooCommerce displays the wrong price due to using the wrong tax rate.
I entered the tax rates for all EU countries and left the rest blank. When I access the website from an EU country the prices are shown correctly including VAT. When I access the site from another country or with a device set to another country or with an account having a non-EU country set as billing address, I see the price without VAT, which is correct in the cart and checkout, but by law the prices on the product pages must be displayed including VAT at all times. How do I achieve that?

Please excuse my bad English, I hope it’s understandable.
