A price-based tax rule sets the tax rate for one tax class by an item's unit price: the at-or-below rate applies up to and including the threshold, and the above rate applies above it. The price compared is after discounts and before tax; when prices include tax, it is the price without tax at the at-or-below rate. The rule affects item tax only; it does not change tax on shipping, cash-on-delivery charges, or checkout fees.
The at-or-below and above 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. Those rate lines give checkout the jurisdiction and the customer-facing tax-line names. The rule's rate is shared between the lines in proportion to their ordinary rates: with CGST 9% and SGST 9%, a 5% rule charges CGST 2.5% and SGST 2.5%. The rule 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.
