TAX ZONE AND RATES
I have set 0% for active union vat and 19% for non-active union vat https://prnt.sc/ssiam3
TAX RULES: here I add a rule: https://prnt.sc/ssibau
Now I create customer group: Wholesaler Active Union VAT and here I assigned tax classes Active Union VAT 0%: https://prnt.sc/ssibpr
Now I created a new user and assign it to this group with VAT 0%.
Now when I try to place order still Magento add tax 19% https://prnt.sc/ssickm
