I have the problem that for a custom new product type there are no taxes getting calculated and are always 0.

I found a solution here. It says there is a dropdown in the product details called Tax Class:

But there is no such field for me (on any product type). The attribute set is set to default.

Attribute Set "Default":

As you can see an attribute with name "tax_class_id" already exist in this attribute set, but why is it not showing?

  • Hi Black, usually the 'tax_class_id' is inside the advanced_pricing options. I don't know if your custom product has that. But just in case...

If you just create a new Product Type, admin product form does not contain some standard fields like Price and Tax Class. You need to associate this standard common attributes with your new Product Type via InstallData/UpgradeData scripts. Example:

$productEntityTypeId = $eavSetup->getEntityTypeId(\Magento\Catalog\Model\Product::ENTITY);
$fieldsCommon = [ // list of fields you need
foreach ($fieldsCommon as $field) {
    $applyTo = explode(
        $eavSetup->getAttribute($productEntityTypeId, $field, 'apply_to')
    if (!in_array('<new-type-code>', $applyTo)) {
        $applyTo[] = '<new-type-code>';
            implode(',', $applyTo)

I have faced the same issue so you need to change the catalog_eav_attribute table so connect step connect PHPMyAdmin and follow the below step given :

Step 1: Select the database are you using and run the below command

SELECT * FROM eav_attribute WHERE attribute_code LIKE '%tax_class_id%'

enter image description here

Step 2: run the below query

SELECT * FROM catalog_eav_attribute WHERE attribute_id = 136

enter image description here

Step 3 : change the value of apply_to filed like "simple,virtual,downloadable,configurable,bundle"

enter image description here

I am 100% sure your issue resolve after apply the above solution.

Happy coding....

After Vishals suggested solution (which worked for me, thank you): Do not forget to run bin/magento setup:di:compile command.
