This field is accessible only if the Post Taxes on Payments check box is selected in AR Company Parameters.
The field defaults a tax amount based on the tax code and the tax basis (which may differ from the line’s amount).
The line’s Amount must reflex the pre-tax amount. For example, if the Total Amount to apply is 1060.00, and the Tax Amount is 60.00, enter 1000.00 as the line’s Amount. If you override the tax amount calculation, adjust the line’s Amount to ensure the Total Amount to be applied is accurate.
