A price-based tax rule changes the effective rate for one tax class when an item's final unit price crosses a threshold. Discounts are applied first. The rule affects item tax only; it does not change tax on shipping, cash-on-delivery charges, or checkout fees.
The below-threshold and at-or-above-threshold rates must be different, otherwise the rule would have no effect. Either rate may be higher so the rule can represent jurisdictions where tax rises or falls at the threshold.
Why one country and one currency
A threshold is both jurisdiction-specific and currency-specific. The current rule belongs to a market and tax class, not to separate countries or currencies, so it is available only when the market has exactly one country and one currency. This prevents one country's rule or one currency amount from being applied as though it meant the same thing elsewhere.
Rate coverage still matters
The tax class must still have an ordinary tax rate in every zone where the rule should apply. That rate gives checkout the jurisdiction and the customer-facing tax-line name. The price rule replaces the class's effective percentage for the item; it does not create a missing zone-and-class combination.
Changing market countries or currencies
A market with price-based tax rules cannot add a second country or currency. Delete the rules first, change the market, and then configure ordinary zone rates for the new setup.
On mobile
In the Tringify app, open Markets, choose the market, and then go to Tax > Price rules. You can create, edit, and delete price-based tax rules when the market is eligible.
