Tax implementation in woocommerce can be activated from the settings so as to view the customers the tax charges involved with their purchase.
S1: Go to woocommerce settings and click on the Tax tab.
There select the option saying “No, I will enter price excluding tax”. This means that the prices that you allot to the products does not include tax. The tax that is set by you is charged to the customer during the checkout.
S2: Click on the standard tax rates section at the top to create a tax based on the country/state your store is in.
Setting and saving the changes results in tax implementation. Thus when a customer adds the product and glances at the final total, it comes with the tax.
