To comply with Place of Supply requirements, you can use the VAT Rules table to define when not to charge VAT tax. You do not need these rules unless your organization faces one of these situations:
■ You hold online (virtual) events.
■ You hold in-person events in another EU country.
■ Your tax advisor determines that charging VAT on all non-exempt registrants is incorrect.
You can create as many rule sets as you need to handle the situations you must support. When you define a VAT-enabled event, you select which of your rule sets you want to apply, and your registrants — whether registered in Desktop, Web, or Public views — see confirmation that their fees include the required VAT taxes.
