How do I update legacy tax values

AI generated answer (using internal Slack threads):

To update legacy tax values in NetSuite, you would typically need to adjust the tax items associated with the relevant transactions. However, it's important to note that the tax calculation is often determined by the Nexus, which is triggered by the 'ship to' address for sales and by the Vendor Default ship address for purchases. If you're experiencing issues with incorrect tax calculations, one workaround could be to manually adjust the address record to your liking, but use the override to adjust the text. This could potentially correct the tax calculation without needing to upgrade to SuiteTax. However, please be aware that this is a workaround and may not be suitable for all situations. It's always recommended to thoroughly test any changes in a sandbox environment before implementing them in a live instance. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
