Originally paid taxes (ticket column) are compared with the new taxes calculated by the system (Fare Quote column) and the positive difference is shown in the ADC column.
If due to some specific reason you do not want to collect the tax difference, it is possible to switch off the bulb in Collect ADC and the tax difference will not be calculated, but such a decision is always agent's responsibility.
The negative tax difference is not refunded automatically, but it is possible to return the unused tax, or the residual value of the tax already paid by switching on the relevant bulb in the Do refund column.
It is possible to add some tax which is not returned by the system automatically or is calculated on the lower level - see the example below in this chapter.

Originally paid Fare (ticket column) is compared with the new Fare calculated by the system (Fare Quote column) and the positive difference is shown in the ADC column. The negative Fare difference is not refunded automatically but it is possible to return the residual value by switching the relevant bulb in the Do refund column. Such a decision is always agent's responsibility and the appropriate Fare rule (category 16) must always be checked in advance.
Ticket Additional collection = tax plus Fare ADC / Refundable balance = tax plus Fare refund.
