Some WooCommerce store owners like to display the prices of their variable products with and without tax. For example, you might want to display the price at the top of a variable product page as “From $100 excl. tax / $120 inc. tax”. This can be done with Variation Prices!
When you configure the product, choose a “Custom format” for your variation prices. You can then use the following merge tags to show prices exclusive or inclusive of tax or VAT:
{min_inc_tax}
{min_exc_tax}
{max_inc_tax}
{max_exc_tax}
