How the system calculates inc and ex tax

Modified on Fri, 7 Feb, 2020 at 2:30 PM


If you add a negotiated charge line and set the TAX to EX TAX this means the negotiated rate excludes the 20 % TAX


If you add a negotiated charge line and set the TAX to INC TAX this means the negotiated rate includes the 20 % TAX


Therefore the Inc TAX column in the summary of charges will show a higher rate than the Ex Tax column because it's adding the TAX to the negotiated EX TAX charge line.


Please note that you will only see the Ex Tax and Inc TAX column in the summary of charges box within an event booking.

People sometimes get confused about this when looking at the charges in an enquiry because the enquiry doens't show the summary of charges in the same way the event booking does. It will only show the summary of charges as inc TAX


We are often asked why when setting the TAX column to INC TAX we end up with a lower rate that when setting it to EX TAX.


If you add a negotiated charge line and set the TAX to EX TAX this means the negotiated rate excludes the 20 % TAX


If you add a negotiated charge line and set the TAX to INC TAX this means the negotiated rate includes the 20 % TAX
