I am explaining here a way to remove the estimated tax block seen in the summary section of cart page
Create a file checkout_cart_index.xml at the location app/design/frontend/Dw/green/Magento_Checkout/layout/ (Dw/green is a custom theme)
Copy the content as seen below in the layout file
<?xml version="1.0"?> <page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd"> <body> <referenceBlock name="checkout.cart.shipping"> <arguments> <argument name="jsLayout" xsi:type="array"> <item name="components" xsi:type="array"> <item name="block-summary" xsi:type="array"> <item name="config" xsi:type="array"> <item name="componentDisabled" xsi:type="boolean">true</item> </item> </item> </item> </argument> </arguments> </referenceBlock> </body> </page>
Also in case you want to remove the heading as well than copy vendor/magento/module-checkout/view/frontend/templates/cart/shipping.phtml file to app/design/frontend/Dw/green/Magento_Checkout/templates/cart and comment/remove the below mentioned part
<div class="title" data-role="title"> <strong id="block-shipping-heading" role="heading" aria-level="2"> <?= /* @escapeNotVerified */ $block->getQuote()->isVirtual() ? __('Estimate Tax') : __('Estimate Shipping and Tax') ?> </strong> </div>
Hope this is helpful
