How to remove “Estimate shipping costs and tax” block from cart page in magento 2

To remove the “Estimate shipping costs and tax” block from the cart page:

#1 Add the following code to checkout_cart_index.xml in your theme (create a new file if it doesn’t exist). The file should be in app/code/design/frontend/<Theme_Vendor>/<Theme_Name>/Magento_Checkout/layout/.

#File: app/code/design/frontend/<Theme_Vendor>/<Theme_Name>/Magento_Checkout/layout/checkout_cart_index.xml

<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>

#2 Override the template file cart/shipping.phtml in your theme (or module) and remove the following lines

<div class="title" data-role="title">
	<strong id="block-shipping-heading" role="heading" aria-level="2">
		<?= $block->getQuote()->isVirtual()
			? $block->escapeHtml(__('Estimate Tax'))
			: $block->escapeHtml(__('Estimate Shipping and Tax'))
		?>
	</strong>
</div>

Then clear your cache and you are good to go 🙂
