Hi Brenda,

Here is a link to a technical tip on our website, for examples of setting up HST in Adagio:

HST technical tip

If you want to have a tax (transit) added to the tax base for another tax (HST), then first ensure that the transit tax is defined as the first jurisdiction in your Tax Table, followed by HST, reading tabs from left to right. For the transit tax, click the 'Taxable' checkbox and this tax amount will be added to the tax base of all subsequent taxes (ie HST). This applies to both Adagio Invoices and Adagio OrderEntry.
