I have removed tax block from all sales page by adding following code.
layout file is Magento_Sales\layout\default.xml
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>
<referenceBlock name="tax" remove="true"/>
</body>
</page>
How can I make subtotal shows including tax but tax line is removed by <referenceBlock name="tax" remove="true"/>
?
