Magento does not provide any configuration to include and exclude tax prices on the product detail page, so I will show how to do that technically.
Magento 2 default displays the original product price as configured from the admin panel. It does not include the tax amount that a customer has to pay. The benefit of tax prices on the product detail page has the customer can see the tax price of the product and is not conceiving off guard at the end of the purchase.
Excluding Tax: Prices that appear on the storefront do not include tax.
Including Tax: Prices that appear on the storefront include tax.
We are already learned how to create a basic module in Magento 2. We need to create module.xml and registration.php files. You can create module.xml and registration.php from this tutorial.
Here we are using Dolphin as Vendor name and Price as the name of the module. You can change this according to your Vendor and Module name.
Create dependency injection file di.xml in the app/code/Dolphin/Price/etc folder with the following code.
<?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd"> <type name="Magento\Catalog\Helper\Data"> <plugin name="Dolphin_Catalog_Helper_Data" type="Dolphin\Price\Plugin\Catalog\Helper\Data" sortOrder="10" disabled="false" /> </type> <type name="Magento\Tax\Pricing\Render\Adjustment"> <plugin name="Dolphin_Tax_Pricing_Render_Adjustment" type="Dolphin\Price\Plugin\Tax\Pricing\Render\Adjustment" sortOrder="10" disabled="false" /> </type> <type name="Magento\Framework\Pricing\Adjustment\Calculator"> <plugin name="Dolphin_Framework_Pricing_Adjustment_Calculator" type="Dolphin\Price\Plugin\Framework\Pricing\Adjustment\Calculator" sortOrder="10" disabled="false" /> </type> </config>
Create the plugin class file View.php in the app/code/Dolphin/Price/Plugin/Catalog/Helper folder with the following code.
<?php namespace Dolphin\Price\Plugin\Catalog\Helper; use Magento\Tax\Api\Data\TaxClassKeyInterface; class Data extends \Magento\Catalog\Helper\Data { public function aroundGetTaxPrice( \Magento\Catalog\Helper\Data $subject, callable $proceed, $product, $price, $includingTax = null, $shippingAddress = null, $billingAddress = null, $ctc = null, $store = null, $priceIncludesTax = null, $roundPrice = true ) { if (!$price) { return $price; } $store = $this->_storeManager->getStore($store); if (1) { if ($priceIncludesTax === null) { $priceIncludesTax = $this->_taxConfig->priceIncludesTax($store); } $shippingAddressDataObject = null; if ($shippingAddress === null) { $shippingAddressDataObject = $this->convertDefaultTaxAddress($this->_customerSession->getDefaultTaxShippingAddress()); } elseif ($shippingAddress instanceof \Magento\Customer\Model\Address\AbstractAddress) { $shippingAddressDataObject = $shippingAddress->getDataModel(); } $billingAddressDataObject = null; if ($billingAddress === null) { $billingAddressDataObject = $this->convertDefaultTaxAddress($this->_customerSession->getDefaultTaxBillingAddress()); } elseif ($billingAddress instanceof \Magento\Customer\Model\Address\AbstractAddress) { $billingAddressDataObject = $billingAddress->getDataModel(); } $taxClassKey = $this->_taxClassKeyFactory->create(); $taxClassKey->setType(TaxClassKeyInterface::TYPE_ID) ->setValue($product->getTaxClassId()); if ($ctc === null && $this->_customerSession->getCustomerGroupId() != null) { $ctc = $this->customerGroupRepository->getById($this->_customerSession->getCustomerGroupId()) ->getTaxClassId(); } $customerTaxClassKey = $this->_taxClassKeyFactory->create(); $customerTaxClassKey->setType(TaxClassKeyInterface::TYPE_ID) ->setValue($ctc); $item = $this->_quoteDetailsItemFactory->create(); $item->setQuantity(1) ->setCode($product->getSku()) ->setShortDescription($product->getShortDescription()) ->setTaxClassKey($taxClassKey) ->setIsTaxIncluded($priceIncludesTax) ->setType('product') ->setUnitPrice($price); $quoteDetails = $this->_quoteDetailsFactory->create(); $quoteDetails->setShippingAddress($shippingAddressDataObject) ->setBillingAddress($billingAddressDataObject) ->setCustomerTaxClassKey($customerTaxClassKey) ->setItems([$item]) ->setCustomerId($this->_customerSession->getCustomerId()); $storeId = null; if ($store) { $storeId = $store->getId(); } $taxDetails = $this->_taxCalculationService->calculateTax($quoteDetails, $storeId, $roundPrice); $items = $taxDetails->getItems(); $taxDetailsItem = array_shift($items); if ($includingTax !== null) { if ($includingTax) { $price = $taxDetailsItem->getPriceInclTax(); } else { $price = $taxDetailsItem->getPrice(); } } else { switch ($this->_taxConfig->getPriceDisplayType($store)) { case Config::DISPLAY_TYPE_EXCLUDING_TAX: case Config::DISPLAY_TYPE_BOTH: $price = $taxDetailsItem->getPrice(); break; case Config::DISPLAY_TYPE_INCLUDING_TAX: $price = $taxDetailsItem->getPriceInclTax(); break; default: break; } } } if ($roundPrice) { return $this->priceCurrency->round($price); } else { return $price; }; } private function convertDefaultTaxAddress(array $taxAddress = null) { if (empty($taxAddress)) { return null; } $addressDataObject = $this->addressFactory->create() ->setCountryId($taxAddress['country_id']) ->setPostcode($taxAddress['postcode']); if (isset($taxAddress['region_id'])) { $addressDataObject->setRegion($this->regionFactory->create()->setRegionId($taxAddress['region_id'])); } return $addressDataObject; } }
Create the plugin class file Calculator.php in the app/code/Dolphin/Price/Plugin/Framework/Pricing/Adjustment folder with the following code.
<?php namespace Dolphin\Price\Plugin\Framework\Pricing\Adjustment; use Magento\Framework\Pricing\SaleableInterface; class Calculator extends \Magento\Framework\Pricing\Adjustment\Calculator { public function aroundGetAmount( \Magento\Framework\Pricing\Adjustment\Calculator $subject, callable $proceed, $amount, SaleableInterface $saleableItem, $exclude = null, $context = [] ) { $baseAmount = $fullAmount = $amount; $previousAdjustments = 0; $adjustments = []; foreach ($saleableItem->getPriceInfo()->getAdjustments() as $adjustment) { $code = $adjustment->getAdjustmentCode(); $toExclude = false; if (!is_array($exclude)) { if ($exclude === true || ($exclude !== null && $code === $exclude)) { $toExclude = true; } } else { if (in_array($code, $exclude)) { $toExclude = true; } } if ($adjustment->isIncludedInBasePrice()) { $adjust = $adjustment->extractAdjustment($baseAmount, $saleableItem, $context); $baseAmount -= $adjust; $fullAmount = $adjustment->applyAdjustment($fullAmount, $saleableItem, $context); $adjust = $fullAmount - $baseAmount - $previousAdjustments; if (!$toExclude) { $adjustments[$code] = $adjust; } } elseif (1) { if ($toExclude) { continue; } $newAmount = $adjustment->applyAdjustment($fullAmount, $saleableItem, $context); $adjust = $newAmount - $fullAmount; $adjustments[$code] = $adjust; $fullAmount = $newAmount; $previousAdjustments += $adjust; } } return $this->amountFactory->create($fullAmount, $adjustments); } }
Create the plugin class file Adjustment.php in the app/code/Dolphin/Price/Plugin/Tax/Pricing/Render folder with the following code.
<?php0 namespace Dolphin\Price\Plugin\Tax\Pricing\Render; class Adjustment { protected $request; public function __construct(\Magento\Framework\App\Action\Context $request) { $this->request = $request; } public function aroundDisplayBothPrices( \Magento\Tax\Pricing\Render\Adjustment $subject, callable $proceed ) { $objectManager = \Magento\Framework\App\ObjectManager::getInstance(); $request = $this->request->getRequest(); if ($request->getFullActionName() == 'catalog_product_view') { return 1; } else { $result = $proceed(); } } }
Result:-
After you implement the above code, check the output on the product page. The tax prices will be displayed on the product page.
