You can develop an option to include the country and the taxe affiliated. But it will be a an important development.
Like @Eolia said, you can manage and display the product with or without taxes but in your case, you have another element, it's the country.
If you are in B2B only, you can manage that and all the people make a subscription inside your site, you can add this people inside a group.
For example you can create a group called France, with taxes, and another group Switzerland without taxes.
it can solve a part of your problem.
