If your company is based in the EU, you can enter your VAT ID on the upgrade page or via Profile Settings - Billing tab. Your subscription may be subject to the appropriate VAT tax rate if you do not provide your VAT ID at the time of the payment,
If you're having problems with your VAT ID, please make sure that it has the two-letter country code in the front (e.g. DE12345678 or FR9238128).
We check the VAT IDs using VIES, which unfortunately has random downtimes. If you're having trouble with getting your VAT ID validated, please check again in ten minutes.
