On the left-hand side of your Weebly dashboard, click Setup → Taxes

Repeat for all European Union member states.
Under Tax Calculations, click “Charge tax on shipping rates.” If you've inputted all of your shipping addresses and are using Weebly's automatic tax calculator, it'll automatically override charging tax on shipping to states where it's not necessary.
