I have a company registered in Canada and I have designed and prepared 4 stores to sell various products in 1- Germany in EU 2- Arab countries in the south of the Persian Gulf in Asia 3- USA 4- Turkey I have some good friends in each of the above countries, but I do not have a registered company in those countries and my company is registered in Canada. Now I want to set the tax in my stores. My question is, do I have to set a tax for Canada (where my company is registered)? or does each store have its own country tax? Please give a full explanation.
