In order to add TAX / VAT with your WooCommerce products into Google Merchant, you have two different ways to follow depending on which region you want to make the feed.
1. VAT with Regular Price for the USA
2. VAT with Regular Price for Outside of USA
1. TAX for the USA:
If your eCommerce shop is based on the United States of America then you have to configure your TAX/VAT settings into Google Merchant Center. Google Merchant will associate the product Price with your VAT/TAX.
2. TAX for the Outside of USA:
When you are making feed for any region outside of the USA you have to select the Google Attribute, Regular Price and set the Value to Price with TAX. Our plugin will automatically add the TAX with your regular price according to your region. And you don’t need to configure any TAX information in Google Merchant.
