Some blends of tax-related options might be confusing to customers and activate a warning. These conditions might happen when the tax calculation method is set to Total or Row, and the prices that both exclude and include tax are presented to the customer or a tax on an item basis in the cart. Because the tax calculation is rounded, the price that displays in the cart might differ from the price that customers think they have to pay.
If your tax calculation is based on a problematic configuration, the following warnings appear:
- Warning. Tax discount configuration might result in different discounts than a customer might expect for store(s); Europe Website (French), Europe Website (German). Please see source for more details.
- Warning. Tax configuration can result in rounding errors for store(s): Europe Websites (French), Europe Websites (German).
