This article will give information of a tax setting where the sales tax credit for trade ins will not exceed the sales tax for the unit/s being purchased by the customer


For example:

  • Mr. Smith is buying a new unit and the Sales Tax payable on that new unit is $250


  • Mr. Smith is trading in a unit and the Sales Tax credit on that unit is $275


  • The Dealership cannot have the Sales Tax credit from the Trade In ($275) exceed the Sale Tax payable from the new Unit purchase ($250) and in this example, it will exceed it by $25


To stop the above scenario then you will need to enable the relevant Tax Setting


How to enable Trade In Tax Credit cannot exceed Unit Tax


  • From the Blackpurl Header > click and then select



  • Go to Settings tab > General Settings > Trade tax credit cannot exceed unit tax


When disabled (as above) -  there will be no limit on the amount of sales tax calculated for trade-in

To enable, move the toggle and there will now be a limit on the amount of sales tax calculated for trade-in

The sale tax credit for trade-ins will now not exceed the sales tax for the new units being sold

Please note:  If your Dealership has Tax included Pricing (our Dealerships in Australia and New Zealand) then this feature will not be available to you
