If you're new to Shoplazza, then before you start selling, you need to determine whether you should charge tax. You might need to register with various tax agencies. After that, you can set up your taxes in Shoplazza to help ensure that you charge the correct rates wherever you sell. Sometimes the base tax rates don't apply to certain products. For example, certain types of children's clothing might be exempt from tax or have a lower tax rate. If the default rates don't apply, then you need to create an override profile.
