I have simple product name is "Test Product" with Price = 100$ Also, I assign the tax class name "Default" with 7% Tax Rate

So how can I Calculate the product price including tax?


$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$ProductId = 1;
$product = $objectManager->create('Magento\Catalog\Model\Product')->load($ProductId);    
$taxCalculation = $objectManager->create('\Magento\Tax\Api\TaxCalculationInterface');
$scopeConfig = $objectManager->create('\Magento\Framework\App\Config\ScopeConfigInterface');    

if ($taxAttribute = $product->getCustomAttribute('tax_class_id')) {
    $productRateId = $taxAttribute->getValue();        
    $taxCalculation = $objectManager->create('Magento\Tax\Model\Calculation\Rate')->load($productRateId);
    $rate = $taxCalculation->getRate();

    if ((int) $scopeConfig->getValue('tax/calculation/price_includes_tax', \Magento\Store\Model\ScopeInterface::SCOPE_STORE) === 1) {
        $priceExcludingTax = $product->getPrice() / (1 + ($rate / 100));
    } else {
        $priceExcludingTax = $product->getPrice();
$priceIncludingTax = $priceExcludingTax + ($priceExcludingTax * ($rate / 100));

Thanks in Advance!

Simply use Magento\Catalog\Helper\Data::getTaxPrice($product, $product->getFinalPrice(), true)

EDIT with code example:

In your constructor, inject like this:

public function __construct(\Magento\Catalog\Helper\Data $taxHelper) {
    $this->taxHelper = $taxHelper;

...and use it in your code like this:

public function doSomething($product) {
    $price = $this->taxHelper->getTaxPrice($product, $product->getFinalPrice(), true);
    // do something with the price

  • This gave me price with excluding tax. How to get including VAT? Nov 19, 2018 at 6:46
  • Then your tax settings are wrong, or your code is called incorrectly, for example it is not executed inside the correct store view. The method is defined in vendor/magento/module-catalog/Helper/Data.php and the 3rd parameter is * @param bool $includingTax return price include tax flag, which is set to true in my example; using Magento 2.1.14 Nov 19, 2018 at 8:22

    Magento 2.3.x \Magento\Catalog\Helper\Data::getTaxPrice() can work. In this function there is if ($this->_taxConfig->needPriceConversion($store)) {. If conversion isn't need by store configuration than the same price is returned. I guess we can use own helper class with same function without needPriceConversion. The function should be called only for display and only once to display price in a particular zone. Avoid adding twice tax. Apr 22, 2019 at 14:41
  • @obscure true, need to some how ignore that to make it work. Also, i used this code instead of @simonthesorcerer code: $price = $this->taxHelper->getTaxPrice($product, $product->getFinalPrice(), true, null, null, null, null, true, true);

  • This is surprisingly the only way I could calculate the correct prices using the checkout session quote object in Magento 2.4.5. Dec 7, 2022 at 8:18
