Resolving Incorrect Tax Rates in NetSuite Connector

Incorrect tax rates on orders can lead to discrepancies in tax totals between NetSuite and your marketplace or cart. By default, NetSuite Connector transmits the tax rate from the marketplace or cart at the time of order creation. If mismatches occur, it's crucial to investigate the following areas within NetSuite:

• Customer Tax Default Setting: Ensure customers are set as taxable by default (this is particularly relevant for US customers). If a non-taxable customer is assigned to an order, it consequently becomes non-taxable, as there is no tax rate for NetSuite Connector to apply.
• Item Tax Schedule: Verify that each item has an appropriate taxable tax schedule assigned. If a non-taxable item is included in an order, it will similarly prevent NetSuite from applying a tax rate. Refer to the Taxable Items section for details on tax schedule assignment.
• Tax Plug-ins: Confirm whether a tax plug-in is installed and appropriately configured. Certain tax plug-ins require specific settings in NetSuite Connector, such as the Avalara plug-in, which necessitates setting a checkbox to prevent the connector from overwriting the designated tax rate.
• Automation Adjustments: Check for any automation within NetSuite that might alter tax rates, customer details, addresses, or other factors that could trigger a recalculate of taxes on orders.
• Line Item Taxes Setting: Ensure that line item taxes are enabled in NetSuite Connector. This can be verified by navigating to Settings > General and ensuring that the box for Line-Item Taxes Are Enabled In Your NetSuite is checked.
• Tax Setting Conflicts: Review for any conflicts between the tax settings configured in NetSuite and those set in the storefront.
• Return Transactions: If incorrect tax rates appear on return transactions, it may stem from sales orders that did not have the correct tax rates applied. To correct this issue, you can enable the Allow Sales Order Tax Rate Correction setting in NetSuite under Connector > Configuration > Setup.

By systematically checking these areas, you can align the tax rates between NetSuite and your marketplace to ensure consistency and accuracy in tax calculations.

Key Points to Remember

• Ensure customer defaults are set correctly to taxable.
• Verify items are assigned the appropriate tax schedules.
• Configure any applicable tax plug-ins accurately.
• Check for automation that could affect tax calculations.
• Enable line item taxes in NetSuite Connector.

Combining these best practices can significantly reduce tax discrepancies, ensuring the integrity of your financial reporting.
