My supplementary tax calculation is not posting the actual VAT value to the correct nominal

****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ****** Based on the conversations, it seems that your issue with the supplementary tax calculation not posting the actual VAT value to the correct nominal could be due to a few reasons. One possibility is that there might be a configuration issue with your tax codes or tax setup. In NetSuite, tax codes are used to calculate the tax amount on transactions and these tax codes need to be correctly set up for accurate tax calculations. Another possibility could be related to the use of the Supplementary Tax Calculation SuiteApp. While this SuiteApp can be used to calculate supplementary taxes, it might not be correctly configured or there might be some limitations or quirks with its use that are causing the issue. A potential solution could be to use a Custom GL line plugin. This plugin can be deployed for every transaction type where non-deductible TAX is possible to be entered, and it can add two GL impact lines - one to credit the expense and another to debit the TAX. However, please note that these are just potential solutions and the actual solution might vary depending on the specific details of your issue. If you continue to face issues, you might need to further investigate the issue by pulling reports for the tax codes and trying to identify what is missing or wrong. Please note that this is a complex issue and might require a deep understanding of NetSuite's tax setup and configuration. If you are not comfortable with this, you might need to seek help from a NetSuite professional or consultant.
