VAT depends on what country you’re from, and the purchase option you choose. If you’re going to pay via credit card, select the license tier and the maintenance period you need, and click “Purchase”. You will be forwarded to the MyCommerce website for the payment. The VAT will be calculated and shown there, depending on the country you specify.
If you prefer to pay via wire transfer, there will be no VAT unless you’re from Czechia.
