The point of origin is used to calculate the charge for shipments made from your store or warehouse, and also determines the tax rate for products sold. When calculating EU taxes, make sure that the Default Tax Destination Calculation for each store view corresponds to the Shipping Settings point of origin.

In the left panel, expand Sales and choose Shipping Settings.
