Hi there,

I’d like to clarify the current situation with an example. Let’s say you’ve added the following products:

• Product A = $100
• Product B = $200
• Product C = $300

If I select “Prices entered with tax” then all products will be added to the cart as is. This option means that the original price entered has already been calculated with the tax. It does not add an additional fee to calculate tax after the fact. Therefore the prices remain as shown above.

However, if I select “Prices entered without tax”, then an additional tax will be added to the checkout process when a customer adds the product to their cart. I can set the taxing levels as my particular needs require. If for example my tax rate is 5% across the board, the final prices for the products listed above (before any additional fees) will be:

• Product A = $105
• Product B = $210
• Product C = $315

This is discussed in more detail here: https://docs.woocommerce.com/document/setting-up-taxes-in-woocommerce/#section-3

I hope this helps to clarify things.
