Resolution
Create new tax zone under
Top > Billing Director > Taxation Manager > Tax Zones
Create tax rates to be applied within the tax zone created earlier under
Top > Billing Director > Taxation Manager > Tax Rates
Populate the new tax zone with the tax rates created on Step 2 and assign it to a country/state or to account(s)
- Consider the tax zone with id 1 (see screenshot from Step 1) to be a default one, which applies if no other tax zone can be applied. Configure it according to the desired taxation model.
