Use this page to specify which GST and PST taxes to turn off and which HST (Harmonized Sales Tax) taxes to turn on before an HST implementation upgrade runs.
Go to Administration > Web Admin > HST Mapping.
Select Enable HST Conversion.
Using the calendar button, select the HST Implementation Date (the date the HST takes effect). The HST implementation upgrade runs automatically on this day.
In the GST Tax #1 dropdown list, select the number corresponding to the tax in your system that is set as GST.
Tip: To find the corresponding numbers for your taxes, go to the Tax Tables page (Administration > Financial Settings > Tax Tables). Right-click and select View Source. Search for the following code: tax_table_id=.
(Optional) If you have a tax set as PST, select it in the Corresponding PST Tax #1 dropdown list.
In the Corresponding HST Tax #1 dropdown list, select the number corresponding to the tax which will replace the GST and PST. This number must be different from both GST Tax #1 and Corresponding PST Tax #1.
(Optional) If you have a second GST tax set in your system, repeat steps (3) to (5) to map it, using the second row of dropdown lists.
Click Save.
Next, complete HST Adjustments.
