There are two ways to calculate your taxes:
1. Based on your store address: set up your tax name and tax rate in % according to the tax regulations of you country.
2. Based on customers shipping address: set up tax rules for targeted countries/regions/cities. Leave fields State and City empty if you want a particular tax to be applied to the whole country. Once a customer reaches your checkout page and fills shipping details, the system applies taxes you have set for a particular location automatically.
If you have different cities with different tax rates but with the same city name, add its zip codes separated by comma clicking the Add button:
There are also two ways to display prices:
1. Excluding taxes: in this case you will see a separate line on checkout page with the name of the tax rate. All prices in your store are shown excluding taxes.
2. Including taxes: in this case all prices in your store are shown including taxes. Information about tax rate will be shown on checkout page after the total amount (in brackets).
