How do I update tax table in legacy tax

AI generated answer (using internal Slack threads):

To update the tax table in legacy tax, it seems that you cannot directly do it via CSV import. However, you can design your own import tool to achieve this. For updating tax code/tax rate for multiple lines on a sales order, you can do this via CSV import. You just need to get the line number or line sequence number in a saved search. Also, if you change the shipping address, then change it back, the tax will recalculate. Please note that these methods are based on the discussions in the Slack threads and may require further testing in your specific environment. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
