why does the use state sales tax add tax codes with 0 rates

AI generated answer (using internal Slack threads):

The use state sales tax adds tax codes with 0 rates because it is a way to handle tax exceptions for certain regions or situations. In NetSuite, tax codes are used to define the taxability of items and transactions. Even if the tax rate is 0%, a tax code is still required to indicate that the item or transaction is taxable, but at a 0% rate. This is particularly useful in situations where an item is taxable in one region but not in another, or if a certain type of transaction is exempt from tax. For example, if you sell an item in a state where you have nexus, the item is generally taxable. However, if you sell the same item to a customer in a state where you do not have nexus, the item is not taxable. In this case, you would use a tax code with a 0% rate to indicate that the item is not taxable in the non-nexus state. In addition, tax codes with 0% rates can be used to handle tax-exempt customers. For example, if a customer is tax-exempt, you would assign a tax code with a 0% rate to their transactions to indicate that they are not subject to tax. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
