VAT should not be applied to companies purchasing from other companies within the EU. This rule will apply to your purchase if you own a professional company located within the EU.

At the checkout page, you can enter your VAT number in a specific field of the purchase order form. When you send in your VAT number, it will be remotely checked and validated with the official European database of VAT numbers.

You can manually check if your VAT number is validated
