Why am I unable to charge customers tax at checkout?

Topic summary

Main issue: A merchant cannot get sales tax to charge customers at checkout. Selecting the product option “include taxes” shows a tax amount that reduces their profit, but the customer is not charged any tax. If the box is unchecked, no tax information appears at all.

Current behavior observed:

  • With “include taxes” checked: a tax amount displays, but it is treated as included in the price, effectively lowering profit rather than adding a separate charge at checkout.
  • With “include taxes” unchecked: no tax line or tax charge appears for the customer during checkout.

Desired outcome: The tax amount should appear at checkout alongside shipping and be added on top of the product price so the customer pays it.

Status: No solution or settings changes were provided in the discussion. The question remains unresolved and seeks guidance on correct tax configuration.

I am trying to have taxes taken out at check out and under the products I am clicking the box that says “ include taxes”. However, it is showing the amount of taxes and taking it out of my profits but it is not actually charging the customer. When I unclick this box it doesn’t say anything about taxes at all. Either way I go it is not charging my customers taxes. I want tax amount to show up at check out with shipping cost and be added to the price. What am I doing wrong?
