How to fix wrong tax being applied on a sale

Web Updated Aug 2026

If tax is wrong on a sale, it’s a tax setting: the product’s assigned tax, the rate, or whether your prices are tax-inclusive. Check these and new sales will be correct.

Step by step

  1. Check the product’s taxConfirm the product is assigned the correct tax (or none, if exempt).
  2. Check the rateConfirm the tax rate itself is set correctly in your tax settings.
  3. Check inclusive vs exclusiveConfirm whether your prices already include tax — a mismatch here makes the tax look wrong.
