A change was added to how the system handles orders/estimates with a zero percent (0%) tax group assigned. To help avoid confusion, any order/estimate with a zero percent tax group assigned will now be treated as if it was tax exempt. This will automatically mark all income on the order to be non-taxable. Previously, even if the assigned tax group had a zero percent rate, it was possible for income on the order to still be marked as taxable. Even though this didn't affect the actual tax charged amount, it was causing confusion on the Sales Tax Liability report. An information message detailing this has also been added when creating or editing tax groups that result in a zero percent rate.
